Description

Disposable gag

Technical field

This utility model relates to medical apparatus field, relates to a kind of disposable gag specifically.

Background technology

At present, run into epilepsy clonus client need clinically when rescuing and prevent its tongue from biting, first use spatula to pry open mandibular joint, then stretch into traditional gag, consuming time longer.Existing traditional gag comprises back seat, the two ends of back seat have " L " shape to stretch foot respectively by chain connection, structure is comparatively complicated, and it is convenient not when placing various conduit and carrying out mouthful transluminal operation, rapidly, and its gag can not be effectively fixing usually, also be unfavorable for placing head lateral position, thus incur loss through delay rescue time.

Summary of the invention

In order to overcome above-mentioned defect, this utility model provides a kind of disposable gag, simple to operate, easy to use, quick, and can be effectively fixing.

This utility model in order to the technical scheme solving its technical problem and adopt is: a kind of disposable gag, comprise gag body, the hollow cavity that one runs through this gag body is formed in described gag body, one end of the hollow cavity of this gag body forms internal orifice end, and its relative other end forms collar extension end, this gag body becomes large gradually from its internal orifice end to the external diameter of collar extension end; The upper and lower two sides of the hollow cavity of this gag body form occlusal surface and lower occlusal surface respectively, on this upper and lower occlusal surface, correspondence is provided with upper teeth draw-in groove and the lower teeth draw-in groove of arc shape respectively, and the convex arc of this upper and lower tooth draw-in groove is all towards the collar extension end of described gag body.

As further improvement of the utility model, described gag body is along the ellipsoidal cross section of its hollow cavity place straight line vertical.

As further improvement of the utility model, described gag body adopts high-molecular polythene material to make.

The beneficial effects of the utility model are: first, this disposable gag can quick insertion and fixing, use procedure is quick, and the rescue for various burst epileptic patient provides more valuable rescue time, thus advantageously in the life security of protection patient; Secondly, this disposable gag by the fixation of upper and lower tooth draw-in groove, difficult drop-off; Thirdly, this disposable gag adopts high-molecular polythene material to make, and nontoxic, be conducive to stopping cross infection, relatively traditional gag also has the effect of compensator or trimmer pressure, reduces the damage to tooth; Finally, this disposable gag is applied widely, is applicable to all kinds of epileptic patient.

Fig. 2 is another viewing angle constructions schematic diagram of Fig. 1.

By reference to the accompanying drawings, make the following instructions:

1---gag body 2---hollow cavity

3---internal orifice end 4---collar extension end

5---upper occlusal surface 6---lower occlusal surface

7---upper teeth draw-in groove 8---lower teeth draw-in groove

Detailed description of the invention

By reference to the accompanying drawings; this utility model is elaborated; but protection domain of the present utility model is not limited to following embodiment, the simple equivalence namely in every case done with this utility model claim and description changes and modifies, and all still belongs within this utility model patent covering scope.

As shown in Figure 1, 2, a kind of disposable gag, comprise gag body 1, the hollow cavity 2 that one runs through this gag body is formed in this gag body 1, one end of the hollow cavity of this gag body forms internal orifice end 3, and its relative other end forms collar extension end 4, this gag body becomes large gradually from its internal orifice end to the external diameter of collar extension end; The upper and lower two sides of the hollow cavity of this gag body form occlusal surface 5 and lower occlusal surface 6 respectively, on this upper and lower occlusal surface, correspondence is provided with upper teeth draw-in groove 7 and the lower teeth draw-in groove 8 of arc shape respectively, and the convex arc of this upper and lower tooth draw-in groove is all towards the collar extension end of gag body.

Described gag body is along the ellipsoidal cross section of its hollow cavity place straight line vertical.

Described gag body adopts high-molecular polythene material to make.

When needs use gag, can the internal orifice end of this disposable gag be inserted in disease population, directly strut the upper and lower mandibular joint of patient, this gag is fixed by the upper and lower tooth draw-in groove of the upper and lower dental articulation of patient, and carrying out suction sputum operation by the hollow cavity of gag body, this gag also possesses the function of bite-block simultaneously.Therefore, the use of this gag, first can conveniently insert and fix, and reduces operating process, increases work efficiency; Secondly, by the fixation of upper and lower tooth draw-in groove, difficult drop-off; Finally, adopt high-molecular polythene material to make, nontoxic, be conducive to stopping cross infection, relatively traditional gag also has the effect of compensator or trimmer pressure, reduces the damage to tooth.This gag is applicable to all kinds of epileptic patient.
