Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0029] figure 1 One embodiment of the invention is shown.

[0030] see figure 1As shown, in this embodiment, the pneumatic air-controlled ventilator includes: a pipeline 11 through which an air source gas with an input pressure greater than 2.8 bar is communicated through an air inlet port, and the pipeline 11 is respectively connected to a gas with an air pressure greater than 2.8 bar. Non-alarm low-pressure alarm valve 2, the first decompression valve 31, the rear end of the first decompression valve 31 is respectively connected to the normally closed valve 4 and the second decompression valve connected in sequence through a three-way pipe (not shown in the figure). Valve 32, normally open valve 5, the normally open valve 5 is connected to the normally closed valve 4 of the control gas cavity through the pipeline 11, and the pipeline 11 between the normally op...

Abstract

The invention relates to a pneumatic gas-controlled breathing machine which takes gas as a power source. High-pressure gas forms periodic operation through a pneumatic valve so as to supply a proper tidal volume and breathing frequency for a patient. The pneumatic gas-controlled breathing machine only needs to be connected with the gas source so as to supply the proper tidal volume and breathing frequency for the patient through a reducing valve and a control valve of the pneumatic gas-controlled breathing machine self, and the control valve of the pneumatic gas-controlled breathing machine can adjust the breathing frequency and the tidal volume. A normally open valve is closed when the normally open valve controls the pressure of a gas cavity body to rise to a set value, control gas in the gas cavity body is controlled by a normally closed valve and is discharged from an air-resistor simultaneously when the normally open valve is closed, and the normally closed valve recovers to be in the closed state, so that gas supply at the rear end of the normally closed valve is stopped, the time slot from the moment to the next time of ventilation of the normally closed valve is the time for the patient to breathe, and then the process from inhaling to exhaling of the patient is finished. The pneumatic gas-controlled breathing machine works repeatedly in the way.

Description

technical field [0001] The invention relates to a medical device, in particular to a pneumatic air-controlled ventilator. Background technique [0002] CN94111392.2 announced a single-air source palm-type emergency ventilator, its purpose is to provide a single air source that is small in size, light in weight, can work normally with only one air source, easy to carry, easy to operate, and suitable for on-site first aid. Air source palm type emergency ventilator. The technical solution is: the single air source palm-type emergency ventilator is specially designed for respiratory rescue in various emergency situations, mainly including air source input port, air flow output port, output flow air resistance, safety valve, air flow Control devices and air-controlled amplifiers, etc., have the advantages of small size, light weight, only one air source can work normally, easy to carry, easy to operate, and low in price. Its shortcoming is: the patient's respiratory rate and ti...
