Technical field
This utility model relates to the switching device at medical oxygen terminal, and relating in particular to a kind of moral mark oxygen terminal changes the switching device at GB oxygen terminal.
Background technology
Respirator is that a kind of ability replaces, controls or change human body normal physiological is breathed, increased pulmonary ventilation volume, improves respiratory function and practice thrift the device of heart reservation ability; In medical treatment, be used to rescue and treat the acute and chronic respiratory failure that a variety of causes causes, to obtain clinical practice widely.Hospital adopts central oxygen supply system that respirator is carried out oxygen supply usually at present; For respirator is connected with central oxygen supply system easily; The oxygen terminal is installed on the body of wall of hospital ward, when using respirator, oxygen plug on the respirator and the oxygen terminal on the body of wall is connected.The oxygen plug of respirator in the market and center support the oxygen terminal of system that two kinds of specifications are arranged; It is respectively GB oxygen terminal; And the GB oxygen plug that matches with GB oxygen terminal, moral mark oxygen terminal, and the moral mark oxygen plug that matches with moral mark oxygen terminal; The GB oxygen terminal moral mark oxygen plug of can not pegging graft, the moral mark oxygen terminal GB oxygen plug of can not pegging graft.If the respirator specification standards of buying before and after many hospitals are different, and are not only expensive bigger with the also unified replacing in oxygen terminal owing to the oxygen terminal is installed within the walls, and trouble.
In order to solve the moral mark oxygen terminal GB oxygen plug of can pegging graft; Chinese patent 201020221560.7 discloses a kind of moral mark oxygen terminal changes GB oxygen terminal converting interface; Comprise oxygen terminal and oxygen plug; It is characterized in that: said oxygen terminal is GB oxygen terminal, and its socket is shaped as circle, and the socket below is the nut fastener; Said oxygen plug is a moral mark oxygen plug, and the plug top has projection; Said oxygen terminal is connected through welding manner with the oxygen plug.GB oxygen terminal converting interface is changeed at existing this moral mark oxygen terminal; Not enough below existing: directly welding between GB oxygen terminal and the moral mark oxygen plug; Must process GB oxygen terminal and moral mark oxygen plug again; Processed complex, processing cost is higher, and has destroyed the internal structure of GB oxygen terminal and moral mark oxygen plug; Owing to fixing through welding between GB oxygen terminal and the moral mark oxygen plug, can't dismantle simultaneously, hospital must integral body buy GB oxygen terminal and the moral mark oxygen plug that is fixed together, and has improved the use cost of hospital.
The utility model content
The technical problem that this utility model solves is: the switching device that provides a kind of moral mark oxygen terminal to convert GB oxygen terminal to, and not only can realize of the switching of moral mark oxygen terminal, and can reduce the use cost of hospital to GB oxygen terminal.
The technical scheme of this utility model is: a kind of moral mark oxygen terminal converts the switching device at GB oxygen terminal to; Comprise a moral mark oxygen plug and a GB oxygen terminal, it is characterized in that, also comprise first adapter and second adapter that are docked and connected each other; Between said moral mark oxygen plug and said first adapter through being threaded; Through being threaded, wherein, have first airway of perforation on the axis of said first adapter between said GB oxygen terminal and said second adapter; One end of this first airway is provided with female thread; The bottom of this female thread is provided with interior stepped hole, and the outer wall of the first airway other end is provided with first ring flange, and an end of said moral mark oxygen plug is provided with the external screw thread that matches with the female thread of said first airway; Have second airway of perforation on the axis of said second adapter; One end of this second airway is provided with the external screw thread pipe that extends axially out; The outer wall of the second airway other end is provided with second ring flange, and said GB oxygen terminal is provided with the female thread that matches with the external screw thread pipe of said second airway; Be connected through bolt between said first ring flange and said second ring flange, first airway and second airway are interconnected.
Be provided with first seal washer between said first ring flange and said second ring flange.
Be provided with annular groove in first airway of first adapter, this annular groove is positioned at the bottom of the first airway female thread, is embedded with second seal washer in the annular groove, and an end face of this second seal washer is close to the hole shoulder of said interior stepped hole.
The endoporus of the center hole of said second seal washer and said interior stepped hole is positioned on the heart line of same hole.
The center hole diameter of said second seal washer equates with the diameter of bore of said interior stepped hole.
The beneficial effect of this utility model is: the female end of first adapter is communicated with through screw thread with an end of moral mark oxygen plug; The other end of the moral mark oxygen plug moral mark oxygen terminal that is used to peg graft; Second adapter and GB oxygen terminal are through being threaded; Be docked and connected each other between first adapter and second adapter, thereby realize that moral oxygen terminal changes the purpose at GB oxygen terminal, this use is novel only need mark the end threading that the oxygen plug is used to connect first adapter with moral and get final product; For Chinese patent 201020221560.7; Need not change the internal structure at moral mark oxygen plug and GB oxygen terminal, process simpler, from having reduced the use cost of processing cost and hospital.
