Abstract

The utility model discloses a convenient mouth gag including a fixing frame, an arm hinged on the fixing frame, a rotating handle arranged on the fixing frame to make the arm open. The fixing frame has a cross shape, four arms which can attach mutually together are hinged under the cross shaped fixing frame, and the rotating handle is rotatably mounted in the middle of cross shaped fixing frame, and forced parts which can be stretched by the lower part of the rotating handle are arranged on the four arms respectively. The utility model has good effect of pulling off; uneasily tooth damage; the mouth gag can prevent the mouth from hurting and entering the mouth too deep, has good fixity and is hard to slip-off, the pain of the patient is eased, and the application is suitable to all hospitals.

Description

Make things convenient for gag

Technical field

This utility model relates to a kind of medical apparatus and instruments, especially a kind of gag of convenient fixing.

Background technology

Clinical widely used gag is made of 1, two support arm, 2, fixed mounts, 3, threaded turning handles three parts at present.Thereby turning turning handle clockwise can push two support arms and open, to reach the purpose of forcing opening, in use there is a lot of weak points in the gag of this design, because present employed support arm is two, though the oral cavity can be strutted, but because will be on tooth with arm supports, so easy damage tooth when strutting, and the gag of two support arms causes gag to move in the oral cavity easily, can not play well secured effect, so in the oral cavity, come off easily, cause inefficiency, also increased the weight of patient's misery, and open behind the oral cavity because patient's mismatching in the gastric lavage process, cause gag to come off, perhaps need the professional to be responsible for having increased labor intensity, and be difficult for during intubate fixing with hands permanent opening device and stomach tube, in the oral cavity, rock easily etc., incur loss through delay rescue opportunity easily.

Summary of the invention

Technical problem to be solved in the utility model is: for solving above-mentioned weak point, provide a kind of stationarity good, can not damage tooth, and can increase work efficiency make things convenient for gag.

For achieving the above object, the technical solution of the utility model is: make things convenient for gag, comprise fixed mount, be hinged on the support arm on the described fixed mount, be installed on the described fixed mount and can make the open turning handle of support arm, described fixed mount is " cross " shape, the below symmetry of described " cross " shape fixed mount is hinged with four support arms that can fit together mutually, rotatable " cross " center that is installed in fixed mount of described turning handle is respectively equipped with the forced section that can be backed down by described turning handle bottom on described four support arms.

Owing to adopted technique scheme, make things convenient for gag, comprise fixed mount, be hinged on the support arm on the described fixed mount, support arm can rotate around the pin joint of fixed mount, be installed on the described fixed mount and can make the open turning handle of support arm, described fixed mount is " cross " shape, the below symmetry of described " cross " shape fixed mount is hinged with four support arms that can fit together mutually, jointed shaft is symmetrically distributed, and four support arms make fixing more firm to tooth, are difficult for coming off from tooth, rotatable " cross " center that is installed in fixed mount of described turning handle, to strut the oral cavity, be respectively equipped with the forced section that can be backed down by described turning handle bottom on described four support arms, the rotation turning handle can back down four support arms, strutting the oral cavity, thereby make things convenient for intubate etc.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further specified.

Fig. 1 is the structural representation of this utility model embodiment, and is the A-A cutaway view of Fig. 2;

Fig. 2 is the vertical view of this utility model example structure sketch map;

Fig. 3 is the structural perspective of this utility model embodiment.

The specific embodiment

As shown in the figure, make things convenient for gag, comprise fixed mount 3, be hinged on the support arm 1 on the described fixed mount 3, be installed on the described fixed mount 3 and can make support arm 1 open turning handle 2, described fixed mount 3 is " cross " shape, the below symmetry of described " cross " shape fixed mount 3 is hinged with four support arms that can fit together mutually 1, described turning handle 2 rotatable " cross " centers that are installed in fixed mount 3, because turning handle 2 is threaded with fixed mount 3, and be respectively equipped with the forced section 11 that can be backed down by described turning handle 2 bottoms on described four support arms 1, just can four support arms that can fit together mutually 1 be opened by rotation turning handle 2 like this passing fixed mount 3, rotate around pin joint thereby reach four support arms 1, the forced section 11 on the support arm 1 is stressed, to reach the purpose that struts the oral cavity.The described tooth support face 4 and the upper teeth of adjacent two support arms 1 in described four support arms 1 adapt, the described tooth support face 4 and the lower teeth of adjacent in addition two support arms 1 adapt, strutting by two support arms 1 so in use, make tooth support face 4 places be fixed on the upper teeth place, the tooth support face 4 of two support arms 1 is fixed on the lower teeth place in addition, to reach better fixing; And the upper end of described tooth support face 4 is provided with and prevents that described support arm 1 from inserting dark stopping means 7, promptly protruding, can stop gag to cause the lower end of support arm 1 to stretch into the dark excessively problem in oral cavity when intubate easily, projection can be stuck in and play collaborative fixed effect on the flank of tooth.The lower end of described support arm 1 is provided with tooth support face 4, described support arm 1 is provided with gag fixture 5 stomach function regulating pipe fixing devices 6, gag fixture 5 can be restraining, and stomach tube fixture 6 can be elastic fixing clip, restraining plays the effect of permanent opening device, it is tied up to can prevent on the neck that gag from coming off, and the numerous inconvenience that cause; Resilient clip plays the fixedly effect of stomach tube, thereby guarantee in the gastric lavage process, the stomach tube that can cause easily because of mismatching of patient situation such as come off has not only alleviated medical personnel's working strength, and has alleviated patient's misery to a certain extent in treatment.

This utility model struts the good fixing effect in oral cavity, has guaranteed the fixing of stomach tube and gag when strutting, and has not damaged tooth, has also alleviated patient's misery simultaneously.
