Respirator system

Abstract

The invention provides a respirator system adopting compressed gas as power and a pneumatic-control operation mode without needing an external power source. The respirator system comprises a mechanical gas-feeding passage which assists a patient in breathing through a plurality of pneumatic control mechanical elements, a manual gas-feeding passage which assists the patient in breathing in a manual mode; a synchronous triggering passage which triggers the mechanical gas-feeding passage to operate so as to assist the patient in breathing when the patient is capable of spontaneous respiration; a gas source low pressure alarm passage which gives out visual and audible alarm when gas source pressure is lower than a gas source critical pressure value; and a gas duct high pressure alarm passage which gives out visual and audible alarm when gas duct pressure is higher than a gas duct critical pressure value. The respirator system adopting a pneumatic and pneumatic-control operation mode can be used in places incapable of providing electric energy such as hyperbaric oxygen chambers, airplanes, submarines and MPI environments, thereby having excellent practicability.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a ventilator system. Background technique [0002] At present, the existing ventilators on the market are mainly divided into two types: pneumatic electronically controlled ventilator and electric electronically controlled ventilator. These two ventilators must rely on external power supply for normal work. Occasions (such as hyperbaric oxygen chambers, aircraft, submarines, and MPI environments, etc.), the above two ventilators cannot be used. And because these two ventilators use external power supply and electrical control methods, there must be a certain amount of electromagnetic interference, which will adversely affect the operation accuracy of the entire ventilator system (breathing air supply, air pressure monitoring, alarm display, etc.), so It also has high requirements for the working environment. [0003] Therefore, there is a need to provide a ventilator system tha...
