Description
Technical field
The present invention relates to field of mechanical technique, and in particular to ventilator mask.
Background technique
Breathing mask provides the method that the oxygen that breathing needs can be transferred to human lung from storage tank, right
For the weak patient of lung functions, breathing mask is then which solve maintain lung functions and keep body normal to oxygen
The problem of demand.
Be directed to need insert nose catheter patient, have at present offer nose catheter socket ventilator mask (such as specially
Benefit number is a kind of breathing mask of pluggable nose catheter of 201721597794.X), however this face mask structure, it is not suitable for having
It needs to suspend respirator treatment halfway a bit but there is still a need for the patients that nose catheter plugs.This kind of patient without being breathed for a long time
Machine treatment, and needs long-term nose catheter treat, is directed to this kind of patient and needs to cease breathing machine when treating, staff just needs
By ventilator and nose catheter synchronize separate after, be placed in nose catheter again, relatively complicated, the setting of nose catheter will necessarily be interfered
To the convenience of the dismounting of mask.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of cover or so detachable ventilator mask, with
Solve existing ventilator mask integral structure is not easy to the technical issues of removing.
The technical scheme is that the ventilator mask that a kind of cover or so is detachable, including cover and breathing
Machine pipe joint offers a corrugated hose interface and nose catheter interface on the cover, which is characterized in that institute
It states the sub- cover that cover is two left and right settings and is detachably connected composition, the junction of two sub- covers is equipped with sealing structure；
Semicircular indentations there are two being opened up on two sub- covers；
When two sub- cover connections, two semicircular indentations splits constitute the nose catheter interface and corrugated hose is inserted
Interface；
One is rotatably connected to for covering the nose catheter interface on any one sub- cover in two sub- covers
Flip lid；
