Mini Micro DC Motor Diaphragm Electric Pump Price

With the continuous advancement of medical technology, sphygmomanometers, as an important medical equipment, are attracting increasing attention. As the core component of the sphygmomanometer, the electric air pump has increasingly attracted the attention of scientific researchers. Today let’s discuss the application of DYX mini air pump in blood pressure monitors.

The function of the micro air pump in the sphygmomanometer is to generate a certain pressure to measure blood pressure. The sphygmomanometer uses a dc pump to inflate and pressurize the cuff so that the pressure in the cuff is higher than the systolic pressure, thus preventing the flow of blood. The sphygmomanometer then gradually reduces the pressure in the cuff by deflating it until the pressure in the cuff is below the systolic pressure and blood begins to flow. At this time, the sphygmomanometer can measure systolic blood pressure and diastolic blood pressure to obtain accurate blood pressure values.

When choosing a dc air pump for a blood pressure monitor, you need to consider the following factors:

1. Performance: Choose a dc air pump with stable performance, high precision and strong reliability. It should be able to provide sufficient pressure and maintain a stable pressure output to avoid errors in measurement results.

2. Size and weight: Considering the portability and ease of use of the blood pressure monitor, choose a micro air pump that is small in size and light in weight. This can make the blood pressure monitor lighter

Convenient, easy to carry and use.

3. Noise: Low-noise micro air pump can provide a better use experience. When selecting, attention should be paid to whether the operating noise of the air pump is within an acceptable range.

4. Durability and reliability: Choose a miniature air pump with good durability and reliability to ensure long-term use and stable measurement of the blood pressure monitor.

How does a portable electric air pump control the pressure within the cuff by adjusting the exhaust port?

There is a piston or diaphragm inside the micro air pump, which reciprocates driven by the motor. When a piston or diaphragm moves in one direction, they suck in gas; when they move in the other direction, they compress it and push it out.

During this process, a micropump compresses and expels gas into the cuff, causing the force within the cuff to gradually increase. When the pressure within the cuff is higher than the systolic pressure, blood cannot pass through the cuff, blocking blood flow. At this point, the micropump will stop inflating and the pressure within the cuff will remain stable.

The sphygmomanometer then gradually reduces the pressure in the cuff by deflating it. This process is achieved by controlling the exhaust port of the micro air pump. When the vent is open, the air in the cuff will be exhausted through the vent, causing the pressure in the cuff to gradually decrease. When the pressure within the cuff drops below the systolic pressure, blood will begin to flow through the cuff. At this time, the sphygmomanometer can measure systolic blood pressure and diastolic blood pressure to obtain accurate blood pressure values.
