Diaphragm air pump for medical equipment

What medical devices can micro air pumps be used for?

Micro air pumps have a wide range of applications in medical equipment. The following are some of the main uses of micro air pumps in medical equipment:

1. Ventilator: A miniature air pump can be used in the oxygen delivery system of a ventilator to provide stable oxygen flow for patients in need of respiratory support.

2. Infusion pump: During the infusion process, the micro air pump can ensure that the liquid is delivered to the patient's body at a constant speed and pressure.

3. Blood pressure monitor: In a blood pressure monitor, a miniature air pump is used to generate and maintain sufficient pressure to accurately measure the patient's blood pressure.

4. Artificial heart support system: In the treatment of cardiovascular diseases, micro air pumps can be used to assist or replace heart function, helping patients maintain their lives.

Technical Specification

What is the working principle of a micro diaphragm air pump in an air wave therapy device?

The micro diaphragm air pump contains a high-speed rotating diaphragm inside. When the diaphragm rotates, it compresses the gas inside the pump and pushes it out

Mouth. The high-speed rotation of the diaphragm generates continuous gas pressure, which drives the flow of gas. The working principle of this diaphragm type enables

Micro pumps have advantages such as low noise, low power consumption, and long lifespan.

The working mode of the air wave therapy device:

The air wave therapy device uses high-frequency air waves to treat human tissues. These high-frequency air waves are generated by a miniature diaphragm air pump

It is generated by gas pressure. When the micro pump delivers gas to the air wave generator of the therapy device, the generator produces high-frequency air

Fluctuations, these fluctuations will act on human tissues in the form of pressure and friction.

What is the working process of a micro diaphragm air pump in an air wave therapy device?

1. Start up and preparation stage: When the air wave therapy device starts up, the micro diaphragm air pump also starts working. At this stage, the diaphragm inside the air pump begins to rotate at high speed. The rotating diaphragm will create a low-pressure area, allowing external air to be drawn into the pump.

2. Compression and delivery stage: Once air is sucked into the pump, the diaphragm continues to rotate and compresses the air. This compression process generates gas pressure, causing air to be pushed towards the air wave generator of the therapy device.

3. Air wave generation stage: When compressed air reaches the air wave generator, the generator utilizes the pressure of these gases to generate high-frequency air waves. These fluctuations act on the human body through specific therapeutic heads or contact surfaces.

4. Stage of therapeutic effect: High frequency air fluctuations act on human tissues in the form of pressure and friction. This effect helps promote blood circulation, relieve muscle tension and pain, and may also help reduce inflammation and improve tissue nutrition supply.

5. Cycle and Continuous Stage: The above process continues during the operation of the therapy device, forming a cycle. The micro diaphragm air pump continuously compresses and delivers air to the air wave generator, ensuring a sustained therapeutic effect.

Performance Test

How does a micro diaphragm air pump provide stable gas pressure and flow rate?

1. Internal structure design: The internal structure of a micro diaphragm air pump has been carefully designed, usually including one or more diaphragms, which will undergo reciprocating motion during the pump's operation. This design allows the pump to inhale and expel the same amount of gas during each reciprocating motion, ensuring the stability of gas flow.

2. High speed rotation mechanism: The diaphragm usually rotates at high speed in micro air pumps. This high-speed rotation enables the pump to complete multiple gas suction and discharge processes in a short period of time, providing continuous and stable gas flow.

3. Gas compression and release: When the diaphragm moves back and forth inside the pump, it compresses the gas inside the pump and pushes it out of the pump. This compression and release process ensures that gas can flow out of the pump body at a constant pressure. In addition, by adjusting the working speed of the pump or controlling the movement stroke of the diaphragm, the pressure and flow rate of the gas can be further adjusted.

4. Valves and Seals: The micro diaphragm air pump is also equipped with components such as valves and seals, which are used to control the inflow and outflow of gas and ensure that the pump does not experience gas leakage during operation. The design and performance of these valves and seals play a crucial role in ensuring the stability of gas flow.

5. Control System: Some advanced micro diaphragm air pumps are also equipped with a control system that electronically controls the pump's working speed and output. This control system can precisely adjust the pressure and flow rate of gas as needed to meet the requirements of specific applications.

How can the intelligent control system of a micro diaphragm air pump achieve automatic adjustment?

The intelligent control system for micro diaphragm air pumps usually involves the following key steps to achieve automatic adjustment:

1. Sensor monitoring: Firstly, the intelligent control system will use sensors to monitor the working status and environmental conditions of the micro diaphragm air pump in real time. These sensors may include pressure sensors, flow sensors, temperature sensors, etc., which can provide real-time data on key parameters such as gas pressure, flow rate, and temperature.

2. Data processing: The collected sensor data is transmitted to the core processing unit of the control system (usually a microprocessor or controller) for processing and analysis. The control system will calculate these data and compare them with the preset set or target values to determine whether it is necessary to adjust the working state of the micro diaphragm air pump.

3. Output control signal: Based on the results of the decision algorithm, the control system will generate corresponding control signals, such as voltage, current, or PWM signals, to drive the micro

The operation of diaphragm air pump. These control signals will be transmitted to the pump through electronic interfaces or drivers to adjust its operating speed and output.

4. Closed loop feedback: The intelligent control system of micro diaphragm air pumps usually adopts a closed-loop feedback mechanism. This means that the system will continuously adjust the control signal based on real-time monitoring data and control results to maintain the stability and accuracy of gas pressure and flow rate. This closed-loop feedback mechanism helps to reduce errors and biases, and improve the robustness and adaptability of the system.

5. User interface and communication: The intelligent control system may also include user interface and communication interface, so that users can set and monitor the working parameters of the micro diaphragm air pump, and interact with external devices or systems. Through the user interface, users can input set values, view real-time data, or perform other control operations. through
