Problems solved by technology

[0003] However, in the existing anesthesia machines, the gas circuit switching device has an opening, and the handle part extends into the opening for switching operation. Generally, the handle closes the opening only in the manual and machine-controlled states. In the middle, there is a gap between the opening and the handle, that is, the inside and outside are connected, which affects the overall appearance of the gas circuit switching device

Abstract

The invention discloses a gas course switching device for an anaesthesia machine and the anaesthesia machine with the gas course switching device. The gas course switching device comprises a valve body, a separator and a handle. One side of the valve body is opened to form an opening, a first gas course channel, a second gas course channel and a third gas course channel are arranged on the valve body, a moving part is movably arranged in the valve body, the separator is arranged on the moving part, and the separator synchronously moves along with the moving part so that the first gas course channel can be communicated with the second gas course channel or the third gas course channel. The handle comprises a handle body and a handle rod arranged on the handle body, the handle body stretches into the valve body and seals the opening constantly, the handle body is connected with the moving part, and the handle body can swing around the rotating axis of the handle body to drive the moving part to move. The handle of the gas course switching device can seal the opening of the gas course switching device all the time, and thus the appearance of the gas course switching device is beautified.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a gas circuit switching device for an anesthesia machine and an anesthesia machine equipped with it. Background technique [0002] In the anesthesia machine, the skin bag and the bellows are two essential gas storage devices for providing gas to the patient. The skin bag needs to be manually squeezed to supply air, while the bellows is supplied with air through the intelligent control of the anesthesia machine. In order to realize the switch between the two air supply modes of the bladder and the bellows, an air circuit switching device is often installed in the connected air circuit. [0003] However, in the existing anesthesia machines, the gas circuit switching device has an opening, and the handle part extends into the opening for switching operation. Generally, the handle closes the opening only in the manual and machine-controlled states, and during the moving proce...
