Description

Technical Field

[0001] The utility model relates to the technical field of gas connector devices, in particular to a multi-style quick gas connector. Background Art

[0002] In order to facilitate the connection between the ventilator and the central oxygen supply station, common hospital wards will provide patients with a wall-mounted fixed oxygen inhalation interface device, which consists of an oxygen terminal connected to an oxygen socket. In this case, the oxygen socket connected to the ventilator end gas tube can be conveniently plugged directly into the central oxygen supply bedside terminal to achieve timely and convenient oxygen supply. At the same time, the ward will become neat, orderly and easy to manage.

[0003] In Chinese patent CN205307526U, an oxygen terminal converter is introduced, which describes in detail the oxygen terminal converter for converting three types of oxygen terminal plugs, namely British, German and national standards, to British, German and national standards. This method removes the terminal conversion itself, namely British to British, German to German and national to national, and still has 6 conversion connection methods. If a hospital has these three types of terminals at the same time, that is, oxygen needs to be equipped with 6 converters, which are very inconvenient to carry and store. If the converter is needed urgently, it takes a long time to find it and it is easy to take the wrong one. However, all 6 converters may be used, and the purchase cost is high. Utility Model Content

Therefore, when different types of butt joint structures are connected to the air outlet end, they can be directly connected and installed through the connecting seat and the connecting port. Therefore, when in use, different butt joint structures can be installed according to different requirements. The redundant connecting ports can be blocked to reduce the conversion frequency and also reduce the purchase cost. BRIEF DESCRIPTION OF THE DRAWINGS
