Abstract

The invention provides a one-way valve which comprises a valve boy, an adapter, a second end air inlet C, a second end air outlet B, a seal ring, a seal gasket and an elastic part, wherein a first internal channel communicated with the outside is arranged inside the valve body, and the end of the valve body is provided with a first end air inlet A of the first internal channel; the adapter is arranged in the first internal channel and comprises a second internal channel communicated with the first internal channel and a side air inlet D arranged on the side of the adapter; the second end air inlet C and the second end air outlet B are respectively located on both ends of the second internal channel; the seal ring is sheathed outside the adaptor and is arranged between the valve body and the adaptor; the seal gasket is arranged between the first end air inlet A and the second end air inlet C and has a shape applicable to sealing the shape of the first end air inlet A, and the edge of the seal gasket is provided with an air outlet opening; and the elastic part is abutted and pressed between the seal gasket and the adaptor. The invention also provides an anaesthesia machine which comprises the one-way valve, and the one-way valve is arranged on an air inlet of the anaesthesia machine.

Description

technical field [0001] The invention relates to the field of valves, in particular to a one-way valve and anesthesia machine. Background technique [0002] After the anesthesia machine is cut off, the anesthesia gas in the anesthesia machine is easy to flow back and leak, causing pollution to the operating room, so the anesthesia machine is generally equipped with a one-way valve to prevent gas backflow. [0003] During the process of realizing the present invention, the inventor found that the one-way sealing effect of the existing one-way valve is not stable. Contents of the invention [0004] The present invention aims to provide a one-way valve, which can solve the problem of unstable one-way sealing effect of the existing one-way valve. [0005] In an embodiment of the present invention, a check valve is provided, which includes: a valve body, which is provided with a first internal channel communicating with the outside world, and the end of the valve body has a fir...
