Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of an anesthesia ventilation system provided by an embodiment of the present application.

As shown in FIG. 1, the anesthesia ventilation system includes an anesthesia vaporizer, a vaporizer connection seat 110, an air inlet interface 120, and an air outlet interface 130.

In some embodiments, the anesthesia ventilation system includes an anesthesia machine main body, and the evaporator connection seat 110, the air inlet interface 120, and the air outlet interface 130 are all located in the anesthesia machine main body.

In some embodiments, as shown in FIG. 1, the anesthesia ventilation system further includes an anesthesia vaporizer 200. In other implementations, the anesthesia ventilation system may not include the anesthesia vaporizer 200. The anesthesia vaporizer 200 can be detachably connected to the vaporizer connecting seat 110.

Wherein, the air inlet interface 120 and the air outlet interface 130 of the anesthesia ventilation system are arranged on the fresh gas branch, and are connected to the anesthesia vaporizer 200 when the anesthesia vaporizer 200 is connected to the vaporizer connecting seat 110.

Specifically, as shown in FIG. 2 and FIG. 3, the anesthesia ventilation system further includes an in-position detection device 141 and a controller 142, and the in-position detection device 141 can be connected to the controller 142.

The in-position detection device 141 is used to detect whether the anesthesia vaporizer 200 is connected to the vaporizer connector 110. Exemplarily, when the in-position detection device 141 detects that the anesthesia vaporizer 200 is connected to the vaporizer connector 110, it sends corresponding information to the controller 142 to notify the controller 142 that the anesthesia vaporizer 200 is connected to the vaporizer connector 110 .

If it is not detected that the anesthesia vaporizer 200 is connected to the vaporizer connection seat 110, the anesthesia vaporizer 200 may not be supplied with air. Thus, gas leakage can be prevented.

When the anesthesia vaporizer 200 is not connected to the vaporizer connector 110 and the in-position detection device 141 cannot detect the vaporizer circuit 230, the controller 142 may determine that the anesthesia vaporizer 200 is not connected to the vaporizer connector 110.
