Omron Blood Pressure Monitor Maintenance Cause Analysis and Solutions

When measuring human blood pressure, the most common thing we see is the Omron blood pressure monitor. Although there are many types of blood pressure monitors, the most accurate one is the mercury-type Omron blood pressure monitor. However, this mercury-type Omron blood pressure monitor is a bit difficult to maintain because it requires very high accuracy. Therefore, we must carefully learn how to repair Omron blood pressure monitors. Then even if this Omron blood pressure monitor fails in the future, we can easily solve it. Next, I will explain in detail the analysis and solutions to the maintenance reasons of Omron blood pressure monitors. I hope it can help friends who have needs in this regard!

How about the Omron electronic blood pressure monitor

In general, the electronic blood pressure monitor produced by Omron is indeed good, but it is a little expensive, but this is also because this brand is relatively Fire, the reason for its large global market share.

The Omron electronic sphygmomanometer is compact and easy to self-measure. It can check daily blood pressure status at all times, so it is especially suitable for home health care and is also very convenient to carry when traveling. Traditional sphygmomanometers require professional medical staff to operate and are inconvenient for home use. The Omron sphygmomanometer allows you to measure blood pressure at home, in the office, etc., without the need for professional medical staff, as long as you follow the Omron sphygmomanometer's product instructions. With correct use, you can measure your accurate blood pressure index and pulse rate, and understand your health problems anytime and anywhere.

Its measurement method is similar to the traditional mercury sphygmomanometer. It measures the brachial artery. Because the arm band is placed on the upper arm, its measurement stability is better than that of the wrist sphygmomanometer, and it is more suitable for older people and higher heart rate. It is used by patients with uneven blood pressure and aging of peripheral blood vessels caused by diabetes, but it is not as convenient as the wrist-type electronic blood pressure monitor.

Is the Omron electronic sphygmomanometer accurate?

The blood pressure measurement error of a genuine electronic sphygmomanometer should be within a reasonable range. Even medical ones will have positive and negative errors. The quality of the Omron electronic sphygmomanometer is Top-notch, measurements you can trust.

It should be noted that most people who use electronic blood pressure monitors do not read the instruction manual carefully and do not really understand how to use it, resulting in measurement errors.

1. First of all, it must be worn in the correct position. Whether it is the upper arm or wrist, it must be worn in the designated position as required.

2. There is a difference between left and right wearing. Most blood pressure monitors can measure on the left and right arms. However, in the measurement mode of the machine, the left and right are separated. For left arm measurement, choose left and for right arm, choose right. Otherwise, the corresponding The sensor has no output.

3. Wearing angle. Due to the different sensor positions of the product, you must follow the usage requirements when wearing it. Whether the display should be parallel to the palm of your hand or 90°, you must read the instructions clearly.

4. Height, this is very important. This is the main indicator that affects accuracy. Generally, when measuring, the electronic sphygmomanometer should try to keep the height at the level of the heart. Do not move during the measurement, and keep your mind relaxed. calm. Some high-end ones have automatic detection functions, such as Omron's HEM-637. If the machine does not reach the level of the heart, it will not pressurize. Whether it is for medical use or home use, the two measurement results may not be the same. This is because your sitting posture, angle, environment, mood changes and other factors will directly affect the measurement results, so the interval between two measurements is generally required to be more than 5 minutes.

1. Mercury leakage failure

1. Reasons for mercury leakage failure

Generally, blood pressure monitors often leak internal mercury. This situation may eventually lead to a certain error in the measurement value of the blood pressure monitor device. This kind of failure usually occurs when the switch of the sphygmomanometer device is turned on, and the mercury column in the tube does not reach the zero scale level, and bubbles and broken columns occur during the pressurization process of the sphygmomanometer device. situation occurs. During the verification process of the sphygmomanometer device, if the mercury in the sphygmomanometer device reaches 38kpa, then the sphygmomanometer needs to be placed in a still state, and observation for two minutes or more is required to finally understand The cause of mercury leakage is mainly due to component failure of the blood pressure monitor device, and there are also some human factors.

2. Repair of mercury leakage faults

When mercury leaks at the lowermost end of the glass tube of the sphygmomanometer device, it means that the sealing rubber gasket at the lower end has broken down. Due to aging, the rubber pad should be replaced. If the spring force of the upper pressure plate of the glass tube of the sphygmomanometer device itself is relatively weak and the glass tube is relatively loose, the internal spring needs to be replaced in time so that the elastic force of the spring can be effective. Increase. When mercury leakage occurs in the switch gap of a mercury kettle, the switch shaft and the screw device above it should usually be tightened in time, and a certain amount of powerful glue can be dripped around the switch shaft device. When the pressure reaches 38kpa, it needs to stay for about one minute. If there is still mercury leakage from the gap of the switch, then it is necessary to replace the internal mercury bottle with a new one in time. When the pressure further rises to 38kpa, if the mercury column at the bottom of the sphygmomanometer device is broken, it can indicate that the internal mercury content is obviously insufficient, and air will enter the glass tube, and it is necessary to immediately Take effective measures to reduce blood pressure, otherwise the internal mercury will emerge from the top of the sphygmomanometer device.

2. The sphygmomanometer cannot be inflated

1. The reason why the sphygmomanometer cannot be inflated

During the measurement and verification process of the sphygmomanometer device, it is easy for the sphygmomanometer to fail to inflate. The phenomenon that the device cannot be inflated usually occurs when the exhaust valve is closed and the pressure cannot really rise when using a rubber ball for pressurization, or the pressure will rise significantly when the internal rubber ball is pinched, but when the rubber ball is let go, the pressure will rise significantly. The mercury column will drop immediately after that. These phenomena can indicate that there is an air leak in the air circuit of the sphygmomanometer device.

2. Analysis of the failure of the sphygmomanometer to inflate

A common strategy in the process of fault repair is to pressurize the sphygmomanometer device, and then separate the mercury storage bottle to the rubber ball. Fold and compress the rubber tube inside the wall strip, and then find out the specific location of the leak based on the drop in mercury. For the screw-buckle type sphygmomanometer device, you can clearly see the rubber tube after opening it. For the pull-out type device, after removing the ball, you can also take out a section of rubber tube from the exhaust valve and continue to If you rub it, you will see cracks on both sides. Cleaning up the debris in the internal cracks in time can effectively solve the air leakage problem of the blood pressure monitor device.

3. The glass tube is not vertical

1. The reason why the glass tube is not vertical

If the glass tube in the sphygmomanometer does not appear vertical, the blood pressure The error of the display value calibrated by the meter device will increase significantly as its internal pressure gradually increases. The positive error value of the error value of the display value should be 38kpa.

2. The glass tube is not repaired vertically

The glass tube inside the sphygmomanometer device can be tilted forward first, and then the spring leaf screw in the casing can be further loosened to remove it. Move the spring piece forward gradually, and then tighten the screw on the spring piece of the sphygmomanometer device.

And you can also tilt the glass tube to the rear, loosen the screw on the spring leaf in the blood pressure monitor, move the spring toward the back, and then tighten the screw effectively. If the material of the casing is aluminum alloy, then Do not tighten the screws too tightly.

4. Large errors in measurement results

1. Reasons for large errors in measurement results

Generally, staff performing measurement verification of sphygmomanometer devices have Mistakes occurred during the operation or the operation methods were unreasonable. A common symptom is that the switch of the sphygmomanometer device is not turned off in time after use. After the upper cover is completely closed, a part of the mercury will leak out from the upper end of the sphygmomanometer glass tube. Or the switch is turned off without tilting to a certain extent, which may eventually cause the part of the mercury column below the zero scale to be blocked from the mercury storage bottle, and be retained by it and the indication value of the glass tube. Among them, the above-mentioned mercury leakage phenomenon will occur after closing the lid. There are also some cases where if the lid is opened during the next operation, the remaining mercury will not return to the zero mark in time, and this part of the mercury will be removed from the scale. The upper part of the glass tube flows out. Usually, parts such as the mercury storage bottle holder and the axis of the switch are prone to leakage of mercury. When these two parts do not form a good fit, they will leak during the pressurization operation of the sphygmomanometer. Causes mercury to erupt.

2. Maintenance of large error in measurement results

When the above fault occurs, the above two parts usually need to be replaced in time, and during the actual work process, There are also some more convenient methods of mercury replenishment. You can use the needle of a syringe to inhale a scientific and appropriate amount of mercury liquid from the spare mercury, then open the upper cover of the sphygmomanometer device and the mercury storage bottle, and remove the top of the glass tube. Use a needle to insert into the small hole of the tablet pressing position, and slowly inject mercury into it, then use the sphygmomanometer device to gently vibrate, and fuse the mercury sprayed out of the mercury storage bottle with the newly injected mercury liquid. . The final amount of mercury liquid injected should meet the basic standards of zero error, and a smaller diameter needle device should be used as much as possible, so that it is easier to prevent the filter from being damaged by the outside world.
