Air pressure double protection system and method for medical equipment

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.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a system and method for dual air pressure protection of medical equipment. Background technique [0002] With the continuous progress and development of society and the change of population structure, medical rehabilitation has gradually gained the attention and attention of the world. Medical equipment is a very important part of medical rehabilitation, and medical equipment is inseparable from many medical and rehabilitation activities today. In medical equipment, many devices use air pressure control. In order to ensure the safe use of equipment, basically all equipment has certain air circuit protection measures. [0003] At present, the existing air pressure protection measures are generally that the controller monitors the signal of the pressure sensor in real time. When the gas circuit is abnormal, the signal collected by the pressure sensor is transmitted to the single-c...
