We are selling the automatic table in the out of the cabinet is generally in a stopped state

Test method is very simple, need to give the table first full of the hair, and then a standard time to be tested when the watch, minutes, seconds, so that they are synchronized, and then placed in the plane position to go 24 hours, then standard Time alignment error and record it. Repeat the above process, respectively, on the watch under the face, the next, the left, the position on the actual error test, and recorded.
In the case of
For example: static test results are: surface +20 seconds / day, face +20 seconds / day, the next -5 seconds / day, the left +25 seconds / day, the +10 seconds / day, the results Watch the actual wear time error of +15 seconds / day.
In the case of
Take the above example, it is clear that the table should be placed at night to put Cartier love bracelet replica down, in order to help reduce the cumulative error when the watch travel time. Only the reasons for the error of the watch and their own watch error characteristics have an accurate understanding, it can better serve you.
Automatic mechanical movement
Automatic mechanical movement is in the general hand-linked list on the basis of an automatic component: automatic Tuo and automatic wheel. Rely on automatic Tuo any direction of rotation can tighten the winding.
We are selling the automatic table in the out of the cabinet is generally in a stopped state, you receive the table, the first need to foot on the winding (clockwise rotation of the watch 25 laps), then as long as you wear enough time every day, To the source of the source to add energy, so that the automatic table normal travel time.
General automatic watch should be worn in the hands of more than 8 hours a day to make up the winding energy, but not absolute. Recommended holidays should wear a table, only to wear in the hands of the clock to add energy, the watch will not stop. Now there is widespread work in the office, watches often appear to stop phenomenon, in addition to the movement of the reasons, because the wearer’s lack of exercise, can not add enough energy to the winding, for such reasons, Winding method to make up.
We advocate the automatic table as little as possible to use the hand on the winding, because the hand on the winding, need to drive a lot of automatic wheel rotation, automatic parts are very easy to wear, so that customers increase the unnecessary maintenance costs.
Mechanical table allows the error range of ± 30 seconds / day, after the Observatory certification movement of the average error range of -4 seconds to +6 seconds / day, the specific error according to the movement used by the watch may not be in accordance with the The higher the price the smaller the error the principle. Automatic mechanical watch the power of the wrist of the wrist to produce energy to the winding winding, a fully automatic mechanical watch on the continuous operation of 36 hours or so: to ensure that the normal daily wear case, can operate about 15 hours, such as More than the above time do not wear or swing (less wear of the wearer) will cause the watch to stop, before wearing the watch should be given the first foot winding.
The number of vibrations per second, calculated in HZ (HZ), 1 Hz = one per second vibration – 32780 Hz = 32780 vibrations per second (common vibration frequency of quartz watch). Oscillator: the watch to make regular vibration of the components to ensure that the time boundaries Cartier love ring replica and measurement (pendulum, hairspring balance wheel or quartz). A complete swing (a total of two vibrations) of a vibrator. Vibration: Oscillator Pendulum One swing between two ends.
High hardness, wear resistance, the appearance of clear lines, bright and clean, known as “wear-resistant material.” Can be used in combination with steel, made of case ring or strap, grain, increase the shell, with surface abrasion resistance and decorative.
Usually the mechanical table daily error is 15 seconds, the Observatory table pay attention to movement, material and manual technology, the daily error requirements significantly reduced to five seconds. Observatory table is a high precision precision timepieces, so also known as precision timepieces. The Observatory is a highly accurate watch that has been tested by the C. O.S.C .: Controle officiel suisse des chronometres. In order to obtain the Swiss official Chronometer Control, each watch must be tested for different thermometer positions for fifteen consecutive days. As the smaller the area of the table, the production of the higher the difficulty, so according to the table diameter and surface area size, can be divided into shell diameter greater than twenty millimeters or surface area greater than three hundred and fourteen square centimeters and the value is less than or equal to the former Two standards. The items evaluated by the Observatory table include: average daily speed, average speed change, maximum speed change, speed difference at different positions, maximum speed difference, temperature impact value, continuous speed and so on.
Quartz table allows the error range of ± 15 seconds / month. Quartz watch travel time by the battery energy-driven, the general battery life is based on the movement used by the watch may be from 12 to 24 months. If your watch has a weak display function, when the battery near consumption, the second hand will be beat every four seconds, if this happens, you should immediately replace the battery. Overdue may cause damage to the parts, if found to go slow, there may be due to Cartier nail bracelet replica lack of electricity, to the authorized service center to detect electricity.
Quartz watch according to the use of the movement and the use of different battery life of 1-2 years. High-grade three-pin quartz watch batteries will run out of the prompt function, the second hand beating abnormalities, that is, every four seconds jump, then remind you to replace the battery, if not promptly replace the battery, may cause the battery leakage and damage the internal parts of the watch The Some customers have a few watches, usually do not wear in order to save power out of the crown to stop the watch, the surface to see the table stopped, in fact, the battery continues to discharge, if not replaced in time, will cause the battery over discharge, So that the battery leakage, the same will corrode the movement, resulting in maintenance costs far more than the replacement of battery costs.

Light kinetic energy wave table as long as there is light energy as long as they can receive radio

Light kinetic energy wave table, as long as there is light energy, as long as they can receive radio waves will never have errors. Citizen wave watches all use light kinetic energy technology, using any visible light source as energy-driven. Long-term power, automatic management, for the wearer to provide a full range of convenience. Citizen is Japan’s first company dedicated to the development of radio watches, and is always the leader in this field.
Functional principle
Radio table through the watch built-in radio receiver and antenna, received by the tower issued by the “standard time” radio, access time calendar and other data,
Automatically correct the time and date of the watch. Standard time imitation Cartier love bracelet radio waves using high-precision cesium atomic watch theory, one hundred thousand years error of one second.
National Time Service Center civilian standard time radio tower is located in Henan Shangqiu, the signal coverage in addition to Xinjiang, Tibet, most of China outside the region. In North Korea, South Korea and Japan in the western region can also receive the tower launched radio signals. At present in the United States, Germany, Japan and other countries also have radio tower. [1]
Have to receive the global multi-channel radio function of the radio table, can receive radio waves from different countries to launch radio signals to achieve automatic time difference conversion. Whether the wearer is in China, the United States, Europe or Japan, as long as the choice of time zone on behalf of the city name, the watch can automatically receive the local standard time of the radio signal, and proofreading time, so that the wearer feel at ease.
Light energy saving function
After the watch is placed in a dark environment, the power saving function can be activated, the drive circuit and the pointer are stopped to save power and reduce the wear of gears and parts. According to the movement of different models, full of electricity in the dark can be kept running for several months to 10 years, when the watch again touch the light, the time to catch up to the current normal time.
The birth of a good table, not just a high-precision mechanical process. In today’s, people need fashion, design and many other elements of the harmonious interpretation of the boutique. Watch strap is no longer a simple watch accessories, and watch manufacturers to leather manufacturing standards require this detail. They made a package of effort in the production of your wrist strap.
Only the perfect combination of mechanical and fashion watches in line with the needs of this era, coupled with the growing global customer demand for personalized, custom demand continues to emerge. Watch the production process as a group of artisans through the hands Replica Cartier jewelry of the warm weaving out of the wonderful ballet, is a life of the leather production process. In the watch industry, few people know this process. It’s like a wonderful ballet. Overture, leather is stored in a closed, to maintain a certain temperature of the thermostat warehouse, the leather and leather making the same leather, leather is not the manufacture of leather scrap. Stock contains a variety of materials: goatskin, calfskin, buffalo leather, ostrich skin, and short crocodile skin and so on. Now, we will open a ballet prelude to your exquisite watch strap.
Look, this wonderful feast of the ballet, it is a strap of the birth process. Fine, manual, repetitive labor. To pay the effort is not better than to do a bag, the price of money from Needless to say. The key, wear in the hands of your high and complex, beautiful mechanical objects are matched, but also let you really feel a good table to bring the comfort and honor.
Production of leather strap
Strict selection of skin, specifications cut
The first act: the process of cutting the leather in advance according to the fixed size, and the combination of the two pieces of leather to the leather strap: the longer paragraph of the paragraph, installed in the case of six o’clock position, and its other head It was cut into a sharp, the strap on the hole in the cut at the same time also played. Strap short section, installed in the case of twelve o’clock position, the other end of it is fitted with clasp. The process of selecting the skin is very strict, with wrinkles, cracks or scratches of leather can not be used. In addition to ensure that the length of the two leather strap appearance is the same pattern, such as crocodile skin pattern and appearance should be consistent.
Production of leather strap
To be retrofitted and modified
Act II: to carry out the whole decoration and modification. Gradually peeling evenly until the center is full, the edge is like a paper-like thickness ratio. Eliminate too thick leather.
Production of leather strap
The third act: bonding.
First put Viledon cloth and leather together, and then glue the glass fiber lining. Exquisite workmanship, as well as the use of precision tools, as in the creation of a work of art.
Production of leather strap
The fourth act: first accurately cut, and marked the needle of each placement.
At this stage, the leather craftsmen to complete the steps, like a rotating ballet scene. Every artisan is used like a variety of instrumental performers, such as stitches, oblique cutting tools, conical drills or peeling knives, which are properly and finely used for leather

Automatic mechanical watch internal movement components are composed of mechanical parts

Structure and composition
Automatic mechanical watch internal movement components are composed of mechanical parts, is based on the clockwork as the driving force of the balance of wrist watches. Mechanical watch is composed of movement and appearance components. The movement includes the drive train, the original movement system, the upper part of the needle system, the escapement speed control system, the pointer system, the movement parts are clamped by the screws to combine them; the appearance parts from the case, dial, Strap and other parts.
Automatic watch structure type more, but the working principle is roughly the same. Automatic winding device installed in the back of the movement, open the back cover that can see. Automatic Swiss watch movement is generally thicker. General reversing wheel structure of the automatic imitation Cartier love bracelet table by the automatic hammer (heavy hammer), reversing wheel, automatic transmission wheel, automatic wheel and other components. Automatic hammer with screws fixed on the center of the automatic shaft. In the role of external force, it revolves around the center, driving the direction of the wheel, the direction of the axle teeth and promote the automatic transmission wheel rotation, automatic transmission wheel to promote automatic wheel, automatic wheel and large steel wheel teeth, so that a large steel wheel A tooth rotates on a tooth. Automatic table is automatically Tuo any direction of rotation can be on the article. Different from the one-way commutation device, bidirectional commutation device or ratchet pawl device. Now more than automatic watches. ETA2892 movement, double lion 46941 movement is the two-way automatic winding is the vast majority of eccentric pendulum (automatic Tuo or automatic hammer), its shape like a semicircular disk, the choice of more heavy quality of the metal And the edge is relatively thick, so most of the quality are on the edge of Tuo, the use of gravity and human arm swing and rotation, and drive a set of gear to tighten the winding to the winding.
Principle of operation
The movement of the watch is driven by the elasticity of the winding, and when it is full of the winding, its torque is large, and as the watch moves away, the winding is loose and its torque is gradually reduced. Watch from the tightening of the clock to 24 hours this time, its torque output is smooth, then travel is also more accurate, the error is small. And more than 24 hours later, the winding torque will drop sharply, travel time error increases. In order to ensure that the watch travel time more accurate, so every day on the regular winding.
Mechanical watch on how to use the fingers back and forth on the bar is better, because back and forth on the article, with a finger to bring back the big wheel, so play a rebound slowdown, to prevent the collision of the gear, and back and forth is also very effort. If you always move forward, the more close the spring when the full, its rebound is also greater, each time the article will appear rebound once, and each rebound will increase the chord gear collision, so that the tip easily broken.
In accordance with the transmission ratio projections, handle head turn 18 laps more, you can meet Replica Cartier jewelry the watch travel time for 36 hours. However, due to the strength of each person is not the same as the winding, and the handle of the water jacket apron frictional force of different sizes, therefore, when the spring is completely relaxed, the handle is best to rotate more than 20 laps. Winding all tight, in theory, can continue to travel 40 hours (except special watches), but after 24 hours can not guarantee the accuracy of the watch travel time.
When the balance of the ball in the static state, to the hairspring to impose a certain moment, that is, on a string, this time do not shake the watch, and balance wheel can automatically swing, then the watch has a high sensitivity. If the need to shake the watch after the move to move, indicating that the watch sensitivity is low. This phenomenon is generally caused by the balance of the balance wheel is too large.
Maintenance attention
Maintenance principle of mechanical watch:
1, automatic watch in the course of the use of its winding can often maintain a certain degree of tightness, so it removed from the wrist, placed immobile, still able to keep more than twenty-four hours of walking time.
2, automatic table used for many years, due to automatic parts wear, its flexibility will be reduced, so every night before going to sleep should also swing the table for a certain time to make up for lack of power
3, automatic table automatic device if the failure, but also by hand tightening the winding, but not on the full Hand winding feel more strenuous, because the automatic part of the gear and automatic hammer will rotate with the rotation of the big wheel.
Mechanical watch adjustment time principle:
Mechanical watch for a long time without standing, mechanical watch winding will be relaxed to the watch stand still, this time, if you want to re-wear, you must first start the new winding, after the calibration time, universal mechanical watch In the winding of the most loose moment, will reveal the hour hand, minute hand slow down or become fast, because this should be on the full winding, so that no calibration time, there is no standard power to drive the pointer, even semi-automatic on the refining table Section, should also be manually used to refining to eight full, and then the implementation of time calibration.

As long as the watch is the name of the watch on the head there will be an icon, this and the car

As long as the watch is the name of the watch on the head there will be an icon, this and the car, watch the logo LOGO must play in the face of the eye, LOGO are generally graphics, but also English letters, such as the full name of the watch Or abbreviation or prefix. Table head of the icon can be considered a beautiful watch “landscape”, on behalf of the original original, Seiko secret agents; counterfeit false watch is often in this subtle place to do bad, fuzzy rough is a common problem.
Rolex watches watch the head of the icon and meaning
Oyster case with Rolex watches, excellent waterproof performance, this is also the structure of the watch table, because only watch the watch is a moving parts, it needs to be often operated, so this place is particularly important seal. Rolex watches are equipped with a screw lock lock structure, tighten the seal will be like a stopper; and here the waterproof seal apron at least two; like the green water ghost (16610LV model) and Dieton series of imitation Cartier love bracelet watches , Waterproof seal apron up to 3 heavy, an increase in the watch case on the outside of the handle tube, pull out the table can see. In the Rolex watch table head, there will be some logo, logo on the Rolex crown GOLO below, with a dot or dash line that there are two, there are two, there are three, these signs represent Watch the case of the material, but also represents the watch case and the handle of the structure. (See photo)
The specific meaning of the logo
Rolex watches watch the head of the icon and meaning
1, a dot on behalf of the watch is PT950 platinum case, the proportion of this precious metal, watch up to compare the pressure hand;
2, two representative of the origin of the watch with 18K white gold or gold case;
3, the three origin can also be understood as a triple waterproof, with such a table of the watch, handle the head tube visible waterproof seal ring. On the basis of triple waterproofing, if the watch case material uses platinum, then the middle of its three origin which will be smaller (see the relevant photos of the first six); if the watch case material using 18K white gold, then its 3 sides of the origin will be relatively small (see the relevant photo of the first five). When the three origin is generally large (see the relevant photo of the first four), the situation is equivalent to the use of dash, usually case material for the 18K gold, 18K gold + stainless steel or pure stainless steel.
4, there is a short line of the most, dash as if it is a “wildcard”, on behalf of the watch is a double waterproof, table for the material for the 18K gold, 18K gold + stainless steel, or pure stainless steel, , This configuration is the most common.
How to buy a good mechanical watch? Watch is a sophisticated timing instrument, the price is higher, the use of time is also long. Watch the quality of good or bad, the user is very concerned about the problem. Therefore, people in the purchase of watches is always better, so good in the selection. But how can we pick a satisfactory quality watch? Usually, people only listen to the machine when the sound of the size of the sound to determine the quality of the watch is good or bad, it is unscientific. Because the quality of the watch is good or bad, mainly to see the actual travel time accuracy. When the machine moves, the sound is balanced, clear and no noise, only that the table machine is not faulty, and can not explain the quality of the watch is good or bad as the only way to pick the watch. It must also be selected from the following:
First, check the watch appearance parts
Watch the appearance from the shell, table mirror, dial and minutes and seconds and other Replica Cartier jewelry aspects of inspection. The case should be no trachoma and obvious scratches, angular symmetry; back cover and the shell of the rotation should be tight; two watch rings and the case of the same distance, the installation of the hole should be in the foot of the shell position The needle is not easy to fall off; table mirror should be no defects and scratches, transparent and bright; three-pin installation is correct, the needle and the needle, between the mirror and the dial should have the correct safety gap; dial and Pointer coating finish is good, no mark, dial scale line or luminous point integrity; head and case between about 0.1-0.3mm gap.
Second, check the sensitivity of the watch
The sensitivity of the watch is the flexibility of its balance wheel. Check the method is:
(1) will not have been on the winding has been moving around the watch gently shake, with the power to shake to observe the second hand moving situation: If the second hand in a very short period of time to stop walking, then the watch on the hair If the second hand to continue to move for a long time, then the watch can not be fully finished foot on the foot (that is, the winding also stored torque), the sensitivity is not high Or the table is faulty.
(2) will not have to stop the clockwork on the watch, slowly turn the head, observe the second hand to start the situation: the less the rotation of the article, the second hand to start the earlier the higher the sensitivity of the table; Or table machine has other failures. But pay attention to the wings of the watch because of the greater the stiffness of the hairspring than the traditional frequency (18000 times / hour) of the table machine to a little more winding on the swing. High sensitivity of the watch, on the foot after a winding time to move longer.
Third, check the pointer pointer spacing and location
Between the table and the table mirror, between the dial and between the three pins should maintain a certain spacing, or mutual collision caused by the normal operation of the table. Inspection can be observed by dialing. The position of the hour hand and the minute hand and the mutual check is normal check method is: the minute hand and hour hand to 3:00, 9:00, observe whether the two needle at right angles; dial to 6 points, whether the needle is a straight line; dial 12 points, Whether the two fingers coincide.
Fourth, check the watch on the body
Normal watch on the article should be easy . Turn the head of the article, the first feel more loose, gradually more tight, when you can not continue to turn forward the head, indicating that the winding has been completely full and the work of the normal work. If you turn the handle when the head of the article, the occurrence of “Cha Cha abnormal sound, or produce teeth and other teeth and other phenomena, then the above mechanism is faulty.
5, check the dialing machine
Watch the needle should be flexible, reliable and pointer rotation evenly. Inspection should focus on check the wheel and the central wheel friction with the tightness. In the dial, if there is no loose or tight feeling, indicating the sub-wheel friction normal and refueling amount, on the contrary, dial machine parts are faulty. The above method of buying a new watch, for the old watch or repair the quality of the inspection can also refer to, but according to the use of the watch as appropriate to reduce the standard.

Watch the meaning of people now is no longer a simple timing tool

Watch the meaning of people now is no longer a simple timing tool. More as a decoration, to highlight the wearing of temperament. But the watch wearing a long time, the color will inevitably look bleak. This is what you need for your love table to do a polishing! Here the watch home to talk about how much money polished it!What is the watch polished    Watch polishing is the surface of the oxidized metal wear off a layer. It is not important to be polished, the question is whether the equipment is good or bad and the operator’s level. If you do not meet the requirements of the watch will cause harm. Because the watch polishing on the technical imitation Cartier love bracelet parameters of the request is very high, so polished watch is a very fine job, professional cleaning (polishing) usually takes 5 days to complete. While the old watch after such a complex professional cleaning, the general can turn to Bacheng newWatch polished method    Case or strap on the local depth of scratches, to focus on the local first use of stone to do grinding. This need to be carried out under the magnifying glass, the purpose is to scrape evenly polished, when the scratches are basically grinding to grinding, select the appropriate size of the sandpaper, along the original pull sand lines to wear, usually the lines are To the dial as the center was radial, so this is a careful living, to a little bit, the effect of grinding out will be so realistic.How much money the watch is polished    Polishing table certainly need a certain cost, but according to the grade of the table and different. So the specific price can not give! For example, on the million watches, maintenance costs are more expensive. According to the provisions of the watch industry associations, tens of thousands of watches, in addition to demolition costs, but also according to the grade of the watch price of one thousandth of the inspection fee. So the price of the watch polished is related to the price of your watch.Magnetic field is a natural “killer” watch, it is easy to be affected by the watch, to the use of serious impact (such as serious stop phenomenon, etc.). At this point the watch must be degaussing “surgery”, the following watch home to tell you how to degenerate the watch, how much money to despise the watch it!    If the watch by the magnetic, and under normal circumstances is to go fast, (serious will stop) If the walk together between the walks, then watch the faster, about 2 hours / day or so, Steel parts are most likely to be magnetized, covering the escapement wheel and escapement fork, as well as gossamer, magnetic energy will affect Replica Cartier jewelry and interfere with the balance wheel vibration cycle. Now live, strong magnetic field can be seen everywhere, the most typical is the handbag of the magnetic buckle, which is a material made of aluminum iron boron, the magnetic force of the big, there are a variety of electrical appliances, so the watch is easy to be not aware of Magnetized.    The easiest way to judge is to use a sharp compass, flat. And then close the watch quickly and repeatedly read the top of the compass, this action also need to change the table several directions, and then repeat the implementation. As long as the needles needles, it means that the watch has been magnetic.Disassembly method of watch    First, with the finished watch degausser, about tens of dollars a (internal is a coil, the middle with a core, then 50HZ AC, alternating magnetic field degaussing), but also homemade.    Second, the watch on a non-magnetic iron on a few days, the magnetic will be transmitted to the iron plate, of course, the greater the volume of iron, by the magnetic capacity is greater, the effect is better.    Third, the watch slowly through a no iron ring, magnetic will stay on the ring.    In general, the quartz watch itself is on the battery does not exist by the magnetization of the argument, if the mechanical watch magnetization is degaussing, if your watch within the warranty can be free demagnetization, if not, you can go to a little Shopping malls, the general name of the shopping malls will watch the watch can help the table degaussing. The price is the master watch the final say, there is no price tag, generally less than 50 yuan.Tissot table as a well-known Swiss watch brand, wearing a lot of people. In the daily use of the watch maintenance work is also necessary to do a good job. A watch that is properly maintained can be used to extend the life of the watch. So how long is the maintenance of the Tissot watch?    From the daily maintenance, the Tissot table should stay a few days to do something simple cleaning. Especially the belt watch, it is best to clean the strap from time to time. So as to avoid odor or stains. From a professional point of view, the best 2-3 years to do a professional maintenance. This will not only keep the watch in a good running state, but also effectively extend its life!Tissot watch watch case maintenance    Tissot watch case, watch table to be often clean, washable with warm water. Sweat, dirt, etc. will corrode the appearance of the material, and can cause individual skin allergies. Buy a new Tissot watch to tear off the protective cover on the back cover, otherwise the sweat will remain in the middle of the corrosion after the cover. Tissot watches to avoid contact with a variety of chemicals, once encountered, to be promptly cleaned, so as not to cause the coating discoloration, loss or other losses.Tissot watch strap maintenance    One day shuttle table strap to avoid contact with moisture and moisture to prevent discoloration and deformation.    Two Tissot watch straps to avoid long exposure to sunlight, to prevent fading.    Three due to Tissot watch strap cortex easy to penetrate, avoid contact with the oil-based substances or cosmetics.

The sphygmomanometer watch is designed by a Singapore doctor and can be used

The sphygmomanometer watch is designed by a Singapore doctor and can be used for 24 hours to monitor blood pressure watch blood pressure monitor BPro. This new type of sphygmomanometer is particularly suitable for people who are not aware of their own symptoms of hypertension. The watch-type sphygmomanometer will not only reduce heart attack rate and stroke rate, but also collect a lot of data.
Introduction to Blood Pressure Meter
This can be the same as the watch, wrist on the continuous wear a few hours or even days, at any time to monitor human blood pressure.
People in the hospital to measure blood pressure, the tension may lead to abnormal blood pressure. In addition, the body’s blood pressure changes at any time, even if a single measurement can be accurate results, it is difficult to reflect the whole picture of the operation of the cardiovascular system.
Scientists say that with the traditional sphygmomanometer that needs to imitation Cartier love bracelet temporarily block arterial blood flow and then deflate to measure blood pressure, the new sphygmomanometer calculates blood pressure by monitoring the velocity of the pulse wave along the velocity of the hand artery. This sphygmomanometer is much lighter than the average portable sphygmomanometer and can be worn like a watch.
Through continuous measurement of blood pressure, this sphygmomanometer allows doctors to understand in detail the wearer’s blood pressure changes, the timely detection of abnormal conditions, and ultimately will be able to use these data to predict the onset of heart disease.
One in every four American adults is suffering from high blood pressure, and one in three do not know that they are suffering from high blood pressure. As the stroke often occurs within 3 hours of awakening, and during this period.
Blood pressure monitor can be divided into two kinds of direct and indirect. The operating principle of the two sphygmomanometers is not the same, the direct type is the pressure sensor to directly measure the pressure change; indirect principle is to control the externally applied to the measured parts of the pressure, and control the results associated with it The information of the generation and disappearance of the Kochian sound is judged. The former regardless of the arteries or veins can be continuous test, which can only measure the arterial systolic and diastolic blood pressure.
The principle of measurement of blood pressure meter is accurate, and its clinical validation is based on auscultation method as a standard, the use of statistical methods to design, in modern blood pressure indirect measurement method, divided into auscultation method Auscultatory method and oscillometric method.
Auscultation method has its inherent shortcomings: First, in the diastolic blood pressure corresponding to the fourth phase or the fifth phase of the problem has been controversial, resulting in a large discrimination error. Second, by listening to Kirsley to determine the systolic blood pressure, diastolic blood pressure, the reading by the doctor’s mood, hearing, environmental noise, the tension of the subjects and a series of factors, easy to introduce subjective errors, it is difficult to standardize.
The principle of auscultation made electronic sphygmomanometer, although the realization of the automatic detection, but still did not completely solve its inherent shortcomings, namely, large error, poor repeatability, susceptible to noise interference.
At present, the vast majority of blood pressure monitors and automatic electronic Replica Cartier jewelry sphygmomanometer using the oscillographic method to indirectly measure blood pressure. The blood pressure was measured by establishing the relationship between systolic blood pressure, diastolic blood pressure, mean pressure and cuff pressure sonic wave.
Because pulse shock wave and blood pressure have a more stable correlation, so the actual application of self-test blood pressure, the use of oscillographic principles of blood pressure measurement than the auscultation method is more accurate. And the wave method to measure blood pressure when the sleeve without sound device, simple operation, anti-external noise interference ability, but also measured the average pressure.
It must be pointed out that from the measurement principle, the two indirect measurement method does not exist which a more accurate problem, it does not mean that the use of mercury pressure meter auscultation method measured by the results than the electronic sphygmomanometer measurement results accurate. Of course, it is considered that the measurement results of the electronic sphygmomanometer are more accurate and erroneous than the results of the auscultation method using a mercury pressure gauge.
