In modern clinical medicine, ventilator, as an effective means to artificially replace the function of spontaneous ventilation, has been widely used in respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. A ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong patients' lives.
In a ventilator, power supplies are used to control capacitors, solenoid valves, and electrical switches that regulate inspiratory and expiratory phases, and monitor gas flow rates. Electricity controls the interior of the ventilator, but does not provide the energy to deliver the breath. The power source operates the ventilator mechanically or pneumatically. The internal hardware converts electrical energy or gas source into mechanical energy to complete the delivery of primary gas as a power transmission and conversion system. Including drive mechanism and output control mechanism. The drive mechanism is a mechanical device that generates airflow to the patient. A typical example of a drive mechanism is a piston powered by an electric motor. The output control includes one or more valves to determine the flow rate of gas to the patient. From an engineering perspective, power transmission and conversion systems can be classified as either capacity controllers or flow controllers. A microprocessor, that is, a single-chip microcomputer composed of an integrated circuit, can sequentially control the above functions.
What are the heart parts of a ventilator?
The motor of the ventilator is the heart part of the ventilator and a device that converts electrical energy into mechanical energy. The high-precision motor used on the ventilator not only has a small body and strong power, but also responds quickly according to the patient's breathing rhythm during operation, providing strong power supply when the patient inhales, and stopping in time when the patient exhales. Turn so that the patient does not feel labored when exhaling. The product application range involves medical equipment, smart home, personal care, hotel bathroom and other fields. In terms of product stability, the brushless motor manufactured by silicon-based power is stable, with large starting torque and low starting current; in terms of noise, the product runs without electromagnetic noise and has little interference, which can be used in environments with high mute requirements; energy consumption , The product is small in size, high in efficiency and low in power consumption, which helps to achieve equipment miniaturization and energy saving.
