Problems solved by technology

[0002] For example, the patent number is CN201820054587.8, a ventilator for emergency department, which includes a ventilator body and an elastic oxygen delivery tube. A liquid crystal display is fixedly installed in the middle of the front outer surface of the ventilator body, and the bottom of the liquid crystal display is close to the breathing apparatus. An oxygen concentration adjustment knob is movably installed on one end of the outer surface of the ventilator body, and a circuit board is fixedly installed inside the ventilator body. One end is fixedly equipped with an oxygen delivery hole, and one end of the ventilator body near the oxygen delivery hole is provided with an oxygen bottle connection, but the disadvantage of this technical solution is that the ventilation volume cannot be adjusted

Abstract

The invention relates to the field of medical treatment, in particular to a breathing machine with a return air treatment function. And the maximum ventilation amount can be adjusted according to actual conditions. The breathing machine comprises a breathing cylinder assembly, a communicating assembly, an exchange driving assembly and a power assembly; the breathing cylinder assembly is connected with the communicating assembly; the communicating assembly is connected with the exchange driving assembly; the exchange driving assembly is connected with the power assembly; the breathing cylinder assembly is connected with the power assembly; and the communicating assembly is connected with the power assembly. An inner-end sleeve and an inner-end expansion sleeve can be relatively rotated and driven, so that a second screw rod slides along a first screw rod, the use length of the first screw rod is expanded, the total stroke of reciprocating motion of a piston cylinder body is changed, and the maximum amount of gas capable of being contained in the piston cylinder body is changed.
