Medical breathing machine with humidifying and warming functions and working method thereof

Abstract

The invention relates to a medical breathing machine with humidifying and warming functions. The medical breathing machine comprises a controller, a humidifying and warming mechanism, an air and oxygen mixing mechanism, a frequency coordination device, an oxygen tank, an air compressor and a mask. Gas is heated through hot water in the spiral pipe, so that the heating uniformity of the gas to be introduced is improved, and the use experience of a respirator user is improved; the air-oxygen mixing proportion can be conveniently adjusted by adjusting the opening degrees of the first flow adjusting valve and the second flow adjusting valve, and the convenience of debugging and using the breathing machine is improved; reciprocating sliding of the sliding block can be simply controlled through the motor, the breathing frequency can be controlled by controlling the positive and negative rotation switching frequency of the motor, the pressure of gas to be introduced can be adjusted according to the lung pressure of a user by controlling the sliding block pushing amount, and the use convenience degree of the breathing machine is improved. And by arranging the waterproof breathable film, the use safety and reliability are improved under the condition that the gas humidification effect is guaranteed.
