Title:
AIR-PRESSURE DOUBLE-PROTECTION SYSTEM AND METHOD FOR MEDICAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/184398
Kind Code:
A1
Abstract:
Disclosed is an air-pressure double-protection system for a medical device. The system comprises a single chip microprocessor. The single chip microprocessor generates a signal source and transmits the same to an air-pressure control circuit, and the air-pressure control circuit outputs a voltage control source. The voltage control source is divided into two paths, wherein one path is connected to an air-pressure control device through an air-pressure control switch, and the other path is connected to a circuit detection unit. When the air-pressure control circuit becomes abnormal, the circuit detection unit outputs a trigger control signal to trigger the air-pressure control switch to turn off the voltage control source, thereby cutting off the air-pressure control device. Further, when the single chip microprocessor determines, by means of a pressure sensor and a pressure acquisition circuit, that the pressure of an air-pressure output device becomes abnormal, a protection signal is outputted to control the air-pressure control switch to turn off, thereby cutting off the air-pressure control device. The present invention can overcome defects of an existing medical device, such as slow air-pressure control response and poor reliability, has an air-pressure double-protection function, and provides a first protection with a response speed that is far more rapid than the response speed of a traditional air-pressure protection measure.
