In detail: do-it-yourself repair of the omron tonometer from a real master for the site my.housecope.com.
Doesn't pump air. Two masters watched - they were resting. What to do?
Any item that has been assembled is disassembled. Accordingly, it should be repaired. Such things as a blood pressure monitor are subject to mandatory certification and an established guarantee. In the event of a breakdown, you should not resort to self-repair or the help of omniscient self-made people.
There are only two ways out - to carry it to a specialized repair (if any) or to acquire a new one.
Without a doubt, you can, and do it yourself!
To repair the equipment, it is necessary to purchase a failed unit in a medical equipment store and replace it with a new one purchased. If your tonometer “does not pump air” then most likely the check valve in the pear-compressor is out of order. The valve itself for the pear-compressor is unlikely to be purchased, but assembled the entire unit is easy. Their unification is based on the diameter of the connecting pipes. Perhaps you will like a node of a different, more modern design (there are a lot of them).
The tonometer can be repaired, but depending on the reason for which it failed. Only a few can do this. And, if there is a tonometer in the house, then it’s not casual, but it’s used and there is a sick person.
Therefore, my opinion is that it is better to go and buy a new one. After all, until you wait for the master, until he fixes, and will he fix it ?! And then, it is not known whether it will give exactly what is needed on the display, because they have already been digging into it.
Tonometers are inexpensive now, we bought a new one for 1,000, and they work fine. And the old children played and threw out.
Don't skimp on your health. Good health to all!

It is no secret that blood pressure is an important indicator for the functioning of the heart, blood vessels, the entire body system and human vitality. There is always at least one person in the family suffering from hypertension. Therefore, the house should have a tonometer for regular monitoring of the main indicator of health. Especially the device is required for the elderly and those who are engaged in heavy physical labor. As a rule, devices are prone to breakdowns, especially mechanical types of tonometers break down. Therefore, the problem of how to repair a tonometer with your own hands is quite relevant.
As a rule, the repair of devices consists in changing the component assembly. Why you need to buy a new mechanism and replace the broken one with it. For example, it is not possible to inflate the cuff with air. This means that the pumping check valve in the bag has broken. It is pointless to change only the valve, you need to replace the entire assembly, along with the tubes.
Electronic and semi-automatic machines are several times higher than a mechanical device. For these types of device, not too frequent malfunctions are noted. Often happen:
- malfunctions in the mechanism itself;
- absence or delay in displaying indicators on the display;
Display problems
It is better to eliminate serious breakdowns in a service center, because a warranty card is issued for repairs, and before its expiration, it is prohibited to carry out repairs on your own. You can change the bulb, cuff, batteries yourself, they are not covered by the warranty card.
If you decide to save time and money and fix the tonometer yourself, then you must first find the malfunction in the device. If a person uses it often, then it will not be difficult to identify the broken part. If the problem is air leaking from the system, then it must be detected. Having found a place for the passage of air, you just need to replace this element with a new one. If after that the pressure measurement went well, then everything worked out.
What breakdowns can a mechanical device have and how to fix them yourself:
-
The cause of the breakdown lies in the falling out of the gauge needle. Here you cannot fix the breakdown on your own. It is recommended to buy a new gauge and replace the broken one with it.

When unrealistic indicators are displayed on the board, it is required first of all to replace the battery. If this does not help, you need to look for air leaks in the cuff, pear and the pipe connecting them. Here, repairs are carried out according to the circumstances: replacement with new parts or elimination of a leak.
A quick solution to the problem - changing the battery
It is not so easy to disable automatic devices. If the tonometer is not dropped, struck or shaken with force, then it will serve for many years. The electronics inside the camera are quite fragile and require delicate and careful handling.
If the problem is bleeding air, then you need to find the place of the gap. When it is located directly on the cuff, it is not necessary to replace it, it can be repaired. How to repair a vented tonometer cuff:
- If the hole is small and the cuff is strong and not worn, then it can be sealed with a hot melt gun.
- You can glue a piece of rubber patch or other suitable material onto the gap with rubber glue.
- Take a strip of thick aluminum and fold it in half. Put the damaged area between them and clamp it with metal, help yourself with pliers. Cover this place with glue.
When the air escapes at the factory soldering site, it can be vulcanized with a soldering iron at 180 degrees. It is important to remember that repairing the cuff is cheaper than replacing it, but it will not last too long after the intervention. Therefore, be prepared to replace this element.
Tonometer model AND UB 201
The AND UB 201 tonometer is a bracelet-type device for measuring pressure indicators. Most often, this model fails the cuff. To repair or replace it, you must remove it correctly. This is done in sequence:
- The batteries are removed from the camera.
- Remove the clamps that secure the cuff (they are located on both sides of the case) by prying them off with a screwdriver.
- Pulling the cuff towards you, release it from the tonometer body, to which it is attached with two more latches.
- The housing cover is attached with two screws at the back, they need to be unscrewed with a screwdriver. Open the cover carefully and remove it.
- To completely disassemble the tonometer, press in the recesses at the top of the case with the same screwdriver, and it will easily fall apart.
Disassembling the device case
The body is assembled in the reverse order. It is important to put all its parts in place and fix them on special "pins".
The question is considered in detail, if the tonometer does not work, what to do. You can contact the service center and hand it over for repair, but it will take a lot of time, extra money will be spent. The breakdown associated with the replacement of an element can be eliminated by yourself - you can buy a new part in a medical equipment store and put it in place of the faulty one.
I welcome everyone! I continue to summarize and lay out in a concise form my experience in electronics repair. Here are my Top 10 most frequent malfunctions of tonometers, which was born as a result of accidental repairs of medical equipment and communication with other Masters. I will not say that I am a great specialist in this area, but I came across something and successfully repaired it. Let's start the rating. The places of malfunction of tonometers and blood pressure meters are sorted by the frequency of occurrence of the malfunction.
If there is a loss of tightness of the pressure supply circuit in your tonometer, then the error "Err Cuf" will most likely be displayed on the screen of the automatic tonometer. Translated from English, cuff is a cuff, so it is logical that the Err Cuf error is a cuff tightness error.
If your tonometer gives such an error, then first of all you need to check the connection between the cuff and the compressor. To do this, you need to remove the cuff. Let's see how to do this using the AND UB-403 wrist tonometer as an example.
How to disassemble an automatic wrist blood pressure monitor AND UB-403
When turned on, this blood pressure meter shows zero.
Then the cuff is pumped, but it is interrupted and the error Err Cuf appears on the display.
We unfold the AND UB-403 tonometer sideways and see a plug that needs to be removed by prying it with a thin slotted screwdriver or an awl.
On the other side of the case, remove the same plug.
This is what these cuff plugs look like.
After that, we remove the cuff of the AND UB-403 tonometer and see the connection points of the nozzles from the compressor to the cuff - there are two of them.
In these places, loosening and air leakage can occur, therefore we carefully inspect and clean the sealing rubber bands of the tonometer pipes and the cuff.
We are trying to put everything together in the reverse order.
If the cuff error persists, check the cuff itself for cracks. This is usually done visually.
The rubber cuff of the tonometer can be repaired by gluing a patch over the air leak. About, how to patch and repair the cuff, see the video below using the Microlife tonometer cuff as an example.
