Medical gas connector device

Abstract

The invention relates to a medical gas connector device. The medical gas connector device comprises a body connected with a medical device, a base connected with the body, an air inlet part connected with the base and an air outlet part arranged in the body. The air inlet part is movably connected to the base. The air inlet part can rotate by 360 degrees at will relative to the base. According to the medical gas connector device, a locking ring is arranged between a connector of the air inlet part and the base, the air inlet part is connected with the base through the locking ring and can rotate by 360 degrees at will relative to the base, installing is flexible, and using is convenient. The functions that ventilation is unavailable when a secondary connector is not connected, and ventilation is immediately conducted when the secondary connector is installed can be effectively achieved by simplifying and optimizing a mechanical structure, opening and closing can be achieved at any time, and the using safety and real-time performance are ensured. Barbs are arranged on an air inlet pipe of the air inlet part and can prevent the air inlet pipe and a hose of an air supply system from disengaging. A clamping ring is arranged at the joint of the air inlet pipe and the connector and can lock the hose of the air supply system, air leakage is prevented, and the air tightness during air inflow is guaranteed.

Description

Technical field [0001] The invention belongs to the technical field of medical gas equipment, and particularly relates to a medical gas interface device. Background technique [0002] At present, many areas of hospitals have air supply ports to provide different gases, such as oxygen, nitrous oxide, carbon dioxide, compressed air, etc., to facilitate treatment. There are different gas supply systems for different gases. For example, when supplying oxygen to hypoxic patients, it needs to be connected to the oxygen supply system; when giving patients anesthesia and pain relief, it needs to be connected to the nitrous oxide (laughing gas) supply system; to deliver oral surgical instruments, orthopedic instruments, ventilators, etc. When powering, it needs to be connected to the compressed air supply system. Because the gas ejected by the gas supply system has a certain pressure, it is necessary to set up a gas connection device between the gas supply port of the gas supply system ...

Problems solved by technology

However, the rotation angle is only 45°, and its adjustable range is small, and it is only used for adjustment during installation. Although it is aware of the problem of adjusting the angle, it cannot be adjusted at any angle during use.
