Description

Self-induction medical gas terminal with gas maintenance function

Technical Field

The utility model relates to the technical field of medical gas terminals, in particular to a self-induction medical gas terminal with gas maintenance function.

Background

Medical gas refers to gas used in medical applications. Some are used directly in therapy; some are used for anesthesia; some are used to drive medical devices and tools; and can be used for medical test, bacteria culture, embryo culture, etc. The common medical gas system with oxygen, nitrous oxide, carbon dioxide, argon, helium, nitrogen and compressed air is a complete set of device for providing medical gas or exhausting waste gas and waste liquid to patients and medical equipment. Common medical gas systems include oxygen systems, nitrogen systems, laughing gas systems, argon systems, carbon dioxide systems, compressed air systems, negative pressure suction systems, anesthesia waste gas discharge systems, and the like. Wherein the negative pressure suction system is used for sucking sputum and purulence, blood and ascites in operation for patients. The anesthesia waste gas discharge system is used for discharging mixed waste gas exhaled by a patient in an anesthesia process. The main components of the anesthetic waste gas are nitrous oxide, carbon dioxide, air, defluoroether, isofluroether and other ether gases. At present, a central gas supply system is generally adopted for supplying medical gas indoors such as hospital wards, operating rooms, monitoring rooms and the like, namely, a gas terminal interface of the central gas supply system is quickly connected with a gas plug to output various required medical gases, and the gas terminal equipment is usually installed on the walls of the wards, the operating rooms or the rescue rooms.

Medical gas terminals typically take the form of a plug-in self-sealing connector. It is composed of a gas self-sealing socket and a gas plug. When the gas plug is used, the hollow gas plug is inserted into the gas socket to push open the valve therein, so that gas in the pipeline can pass through the inner cavities of the socket and the plug. Upon withdrawal of the gas plug, the resilient element in the valve seat closes the flap, prohibiting the passage of gas. Some existing medical gas terminals are exposed in indoor environment for a long time, and germs and dust are easily accumulated at the splicing sleeves, so that the cleanliness requirements of patients on medical gas are not facilitated.
