Medical compressed air supplying device and control method thereof

Abstract

The invention discloses a medical compressed air supplying device and a control method thereof. The device comprises a first air compressor, a second air compressor, an air storage tank, a first filter, a second filter, an air drier, a sterilizing filter and a controller, wherein the first air compressor and the second air compressor are arranged in parallel; the air storing tank, the first filter, the second filter, the air drier and the sterilizing filter are sequentially connected; a first pressure transformer and a first solenoid valve are arranged on an outlet pipeline of the first air compressor; a second pressure transformer and a second solenoid valve are arranged on the outlet pipeline of the second air compressor. According to the device, the controller is used for acquiring the outlet air pressure of the first air compressor or the second air compressor and determining, and then timely switching the use and standby states of the first air compressor and the second air compressor, so that either of the two air compressors keeps running stably all the time to continuously supply stable air pressure, and ensure the life safety of a patient using respirator.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical compressed air supply device and a control method thereof. Background technique [0002] Ventilators have become an indispensable routine medical equipment in medical institutions and are widely used in various clinical departments, especially emergency and intensive care units. The gas supply device of the ventilator includes a compressed air supply device and an oxygen supply device. The compressed air provided by the compressed air supply device and the oxygen provided by the oxygen supply device are mixed in a certain proportion and delivered to the breathing mask for the patient to use. [0003] In the prior art, almost all the air compressors (air compressors) used in medical ventilators have no backup, or are equipped with backup air compressors. When an air compressor fails, the operator will manually switch to Another compressor, however, if there is...

Problems solved by technology

[0003] In the prior art, almost all the air compressors (air compressors) used in medical ventilators have no backup, or are equipped with backup air compressors. When an air compressor fails, the operator will manually switch to Another compressor, however, if there is no backup air compressor or the backup air compressor is not switched in time, it will cause life danger to the patient who needs to use the breathing air in time; A long process of manual switching will cause the pressure of the provided air to be too high or too low, which will have different effects on the patient
