Abstract
A kind of flexibility is exempted to inflate laryngeal mask, including a tool, there are one the airways of rear end and a front end, the front end of the airway is surround by the laryngeal pouch of a non-inflatable, the laryngeal pouch is pre-formed a shape, the front of the laryngeal pouch is equipped with flexible deformable material layer, and the positive end face of the flexible deformable material layer is round slip surface.The front of the laryngeal pouch of the utility model is equipped with flexible deformable material layer, the positive end face of the flexible deformable material layer is round slip surface, sealing is reached by the deformation of flexible deformable material layer, the throat of patient will not be damaged, and then it is equally applicable to child.
Description
Technical field
The utility model is related to a kind of laryngeal masks.
Background technology
Currently known laryngeal mask is divided into two classes, and one kind is inflatable laryngeal mask, and one kind is to exempt to inflate laryngeal mask.Inflatable laryngeal mask is adopted
With air bag, laryngeal mask is put into after patient throat, air bag is inflated, reached after airbag aeration and dissected at the atrium of larynx with patient
Structure forms sealing, and inflatable laryngeal mask has the shortcomings of for example troublesome in poeration, sealing performance is poor, therefore a new generation occurs
Exempt to inflate laryngeal mask（Such as SLIPA laryngeal masks）, however the hardness of this laryngeal mask is larger, may be only available for being grown up, and larger due to rising
Hardness, it is possible to can to the throat of patient formed injure.
Invention content
In order to overcome the above-mentioned deficiency of existing laryngeal mask, the utility model provides a kind of flexibility and exempts to inflate laryngeal mask.
The technical scheme in the invention for solving the technical problem is：A kind of flexibility is exempted to inflate laryngeal mask, has including one
One rear end and the airway of a front end, the front end of the airway are surround by the laryngeal pouch of a non-inflatable, the larynx
Capsule is pre-formed a shape, and the front of the laryngeal pouch is equipped with flexible deformable material layer, the flexible deformable material layer
Positive end face is round slip surface.
Further, the rear portion of the positive end face of the flexible deformable material layer is formed with coherent lug boss, so as to be somebody's turn to do
It is protruded compared with the forepart of the positive end face of flexible deformable material layer at the rear portion of the positive end face of flexible deformable material layer.
Further, the front end of the laryngeal pouch offers deflector hole, has diversion pipe in the laryngeal pouch and airway, described
The front end of diversion pipe connected with the deflector hole.
The utility model operates very simple when in use, it is only necessary to which the laryngeal pouch portion of the utility model is filled in the larynx of patient
Inlet, after laryngeal pouch is reached at the atrium of larynx of patient, positive flexible deformable material layer is by the atrium of larynx of patient
Structure squeezes, and so as to deform, and then reaches the sealing between flexible deformable material layer and patient's atrium of larynx.
The beneficial effects of the utility model are：The front of the laryngeal pouch is equipped with flexible deformable material layer, the flexible variable
The positive end face of shape material layer is round slip surface, reaches sealing by the deformation of flexible deformable material layer, to the throat of patient
It will not damage, and then it is equally applicable to child.
Description of the drawings
Fig. 1 is the structure diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
With reference to Fig. 1, a kind of flexibility is exempted to inflate laryngeal mask, the airway 1 having including one there are one rear end and a front end,
The front end of the airway 1 is surround by the laryngeal pouch 2 of a non-inflatable and the laryngeal pouch 2 does not need to be inflated, itself is
One solid, the laryngeal pouch 2 are pre-formed a shape, the shape cause the shape of laryngeal pouch 2 substantially at the atrium of larynx of human body
Shape be adapted, the front of the laryngeal pouch 2 is equipped with flexible deformable material layer 3, the front of the flexible deformable material layer 3
End face 4 is round slip surface, and the back side of flexible deformable material layer 3 is connect with laryngeal pouch 2.The flexible deformable material layer 3 is preferably by Xiao
The material of A grades of hardness of family name between 0 and 40 is made.Preferably, flexible deformable material layer 3 by Shore A grade hardness 0 to 20
Between material be made.It is further preferred that for material of the flexible deformable material layer 3 by Shore A grade hardness between 0 to 5
The generation type that another flexible deformable material layer 3 is made is that fluid is filled in plastic deformation material layer 3 so as to make it
With certain flexibility and deformability.
The utility model operates very simple when in use, it is only necessary to which the laryngeal pouch portion of the utility model is filled in the larynx of patient
Inlet, after laryngeal pouch 3 is reached at the atrium of larynx of patient, positive flexible deformable material layer is by the atrium of larynx of patient
Structure squeezes, and so as to deform, and then reaches the sealing between flexible deformable material layer and patient's atrium of larynx.
In in the present embodiment, the rear portion of the positive end face 4 of the flexible deformable material layer is formed with coherent lug boss,
So as to which the rear portion of the positive end face 4 of the flexible deformable material layer is convex compared with the forepart of the positive end face 4 of flexible deformable material layer
Go out, so as to reach and the better seal at patient's atrium of larynx by the lug boss when in use.
In the present embodiment, the front end of the laryngeal pouch offers deflector hole 5, has water conservancy diversion in the laryngeal pouch and airway
Pipe, the front end of the diversion pipe are connected with the deflector hole 5, and the diversion pipe and deflector hole cooperation can be used for water conservancy diversion.
Claims (3)
