An emergency transport ventilator

Abstract

The present invention discloses an emergency transport ventilator, which belongs to the technical field of medical devices. The air-oxygen mixing component in the emergency transport ventilator of the present invention includes a first accommodating chamber and a second accommodating chamber opened along a first direction, a first pipe fitting is provided in the first accommodating chamber, a first flow channel is formed in the first pipe fitting, and the output end of the venturi valve is arranged in the first flow channel, a second flow channel is formed between the outer wall of the first pipe fitting and the inner wall of the first accommodating chamber, a third flow channel is formed in the second accommodating chamber, and the third flow channel is connected to one end of the second flow channel close to the valve group assembly. The above-mentioned emergency transport ventilator is provided with the first flow channel, the second flow channel and the third flow channel in the air-oxygen mixing component, while ensuring that the emergency transport ventilator still has the characteristics of miniaturization, and extending the flow channel of the air-oxygen mixed gas flow, so that air and oxygen can be fully mixed, thereby improving the accuracy of the oxygen concentration of the output gas of the emergency transport ventilator.
