Embodiment Construction

[0027] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] figure 1 A gas circuit diagram of a ventilator system according to a preferred embodiment of the present invention is shown in , which uses compressed gas from a gas source 100 (O 2 ) as the mechanical power source of the entire air circuit system, and in particular, the ventilator system can complete various operations in a pneumatically controlled manner through various mechanical components and a specially designed air circuit system, such as breathing air supply, air pressure monitoring , alarm display, etc., without external power supply, so that the ventilator system can be used in occasions where external power supply cannot be provided, such as hyperbaric oxygen chambers, airplanes, submarines, and MRI environments. At the same time, since the external power supply and the corresponding control circuit are eliminated, the electro...

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...
