When both the first air passage 61 (i.e., the oxygen passage) and the second air passage 66 (i.e., the air passage) are in the on state, the switch 1 is in the conductive state, and the anesthesia host can be supplied with power by the mains or the battery or the like through the switch 1; when both the first air passage 61 (i.e., the oxygen passage) and the second air passage 66 (i.e., the air passage) are in the blocking state, the switch 1 is in the power-off state, and the anesthesia host cannot be supplied with power by the mains or the battery or the like through the switch 1; the operation steps of the anesthesia machine are reduced, the user experience is improved, the air channel and the oxygen channel are both in a conducting state when the anesthesia machine is started, and the air channel and the oxygen channel are both in a blocking state when the anesthesia machine is started, so that the safety of the anesthesia machine is improved.
The gas-electricity integrated valve can be applied to a breathing machine, the first air passage is communicated with an oxygen passage of the breathing machine, the second air passage is communicated with an air passage of the breathing machine, and the switch is a main switch of the breathing machine.
The above embodiments of the electro-pneumatic valve of the present utility model are only examples, and are not intended to limit the present utility model, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the scope of the present utility model.
