Double-pressure-protection system and method for medical equipment

Abstract

The invention discloses a double-pressure-protection system for medical equipment. The system comprises a single-chip microcomputer. The single-chip microcomputer generates a signal source and transmits the signal source to a pneumatic control circuit; and the pneumatic control circuit outputs a voltage control source. The voltage control source is divided into two paths: one path of circuit is connected to a pneumatic control device by a pneumatic control switch; and the other path of circuit is connected to a circuit detection unit. When the pneumatic control circuit becomes abnormal, the circuit detection unit outputs a trigger control signal to trigger the pneumatic control switch to turn off the voltage control source, thereby cutting off the pneumatic control device; ; and when the single-chip microcomputer determines that the pressure of an air pressure output device becomes abnormal by a pressure sensor and a pressure collection circuit, a protection signal is outputted to control the pneumatic control switch to be turned off, thereby cutting off the pneumatic control device. Therefore, defects of slow pneumatic control reaction, and poor reliability of the existing medical equipment can be overcome. The system has the dual pressure protection function; and the reaction speed of the first protection measure is far faster than that of the traditional pressure 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...
