Abstract

The utility model discloses a bite block, which comprises a main body and a support wall that extends from the main body, wherein the main body is provided with a slot, convex tubes positioned at two sides of the slot and an exit; the support wall is positioned at the circumambience of the slot; and the convex tubes are provided with through holes lengthways. The bite block can facilitate penetration of endoscopes into human bodies, and the bite block is also provided with through holes and an exit for drainage of spittle and vomit, thus can prevent secretion of the patients from spoiling clothes of medical workers and their own; besides, support wall of the bite block can bear the teeth and the lip to keep the mouth open so that the teeth and the lip are kept away from the endoscope; a rope tied on the hook can also be used to fix the bite block in mouth more firmly.

Description

Bite-block

Technical field

This utility model relates to a kind of bite-block, relates in particular to the bite-block of a kind of auxiliary endoscopic observation, treatment.

Background technology

Along with the progress of medical apparatus and instruments, endoscope has been used for auxiliary observation, treatment various diseases, and is applied in the surgical operations such as beauty treatment, body shaping.But because endoscope need enter inside of human body, endoscope in particular for gastrointestinal examination, can help the doctor to observe esophagus, stomach and duodenum etc., but these endoscopies all need to enter human body from oral area, and this just needs the patient to keep the open posture of face so that endoscope enters, and after in endoscope enters body, face need keep open posture equally, handles pathological changes situation in the endoscopic observation body to make things convenient for the medical worker.But because needs of patients remains the face open configuration, the patient is felt fatigue, and because the stimulation of endoscope easily secretes saliva in the oral cavity, and gather and flow out the oral cavity, in addition because endoscope's stimulating intestine and stomach, make patient's regurgitation vomiting easily, vomitus and saliva all pollute endoscope from meeting can't operate the medical worker, and general vomitus can spue with spurting, also pollute the medical worker easily, make the checking process unhappiness.

Therefore be necessary to provide a kind of promptly convenient patient of support the oral cavity, it is the effusive device of routing that saliva, vomitus are controlled.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of simple structure, makes things convenient for endoscope to enter intravital bite-block.

For solving the problems of the technologies described above, this utility model adopts following technical scheme: this utility model bite-block, comprise the supporting walls that main body, autonomous agent extend, described main body is provided with insertion groove, is positioned at the protruding pipe and the outlet of insertion groove both sides, described supporting walls be located in insertion groove around, described protruding pipe vertically is provided with through hole.

Described supporting walls comprises first, second supporting walls and separates the block wall of first, second supporting walls.

Described supporting walls also is provided with respectively first, second delivery line that connects with outlet, through hole.

Described supporting walls both sides are respectively arranged with expansion arm.

Described main body both sides are respectively arranged with side arm, and the side arm end is provided with hook.

Compared with prior art, the utlity model has following advantage: this utility model bite-block is provided with the insertion groove that inserts for endoscope, and being respectively arranged with the through hole and the outlet of discharging for saliva and vomitus, the medical worker reaches the medicated clothing of oneself thereby the secretions that prevents the patient is made dirty; The supporting walls of bite-block can make tooth and lip support thereon respectively, thereby helps keeping the open configuration in oral cavity, prevents that patient's tooth and lip from touching endoscope; The block wall that the block bite-block moves in the oral cavity is set on the supporting walls, prevents that lip is subjected to the extruding of bite-block; The main body both sides also are provided with hook, come more stably bite-block to be fixed in the oral cavity by means of the binding yarn of tying up on hook during use.

Description of drawings

Fig. 1 is this utility model schematic perspective view

The schematic perspective view of Fig. 2 for seeing from other direction.

The specific embodiment

Please refer to Fig. 1, shown in Figure 2, this utility model bite-block (not label) comprises the supporting walls 2 that main body 1, autonomous agent 1 extend back.

It is tabular that described main body 1 is roughly arc, and its transverse ends extends outward side arm 11 respectively, the curved respectively hook 111 that is provided with of the free end of described side arm 11, and in the illustrated embodiment, hook 111 is two, certain described hook 111 also can be 1 or more a plurality of.About lateral mid-point of main body 1 offers insertion groove 12, and the both sides of insertion groove 12 offer outlet 13 respectively and protruded out protruding pipe 14, and described protruding pipe 14 longitudinally offers through hole 141.

Please refer to shown in Figure 2, it is a square groove similar to the insertion groove 12 of main body 1 that described supporting walls 2 encloses, and supporting walls 2 is for extending back perpendicular to main body 1 around insertion groove 12, described supporting walls 2 extends the block wall 21 that is provided with main body 1 almost parallel up and down respectively, described block wall 21 is divided into first supporting walls 22, second supporting walls 23 with supporting walls 2, and described second supporting walls 23 is between block wall 21 and main body 1.The both sides of described supporting walls 2 are respectively arranged with first, second delivery line 24,25, and the opening of described first delivery line 24 links to each other with the outlet 13 of main body 1, and the opening of described second delivery line 25 communicates with the through hole 141 of the protruding pipe 14 of main body 1.The both sides of described supporting walls 2 also are respectively arranged with expansion arm 26, and the expansion arm 26 of each side is all extended in opposite directions and be curved.

During use, this utility model bite-block is put into the patient oral cavity, fix binding yarn (not shown) on 111 to increase fixing to bite-block at hook, described binding yarn preferably adopts is with elastic binding yarn.Upper and lower row's tooth is stung at the upper and lower sides of first supporting walls 22 to keep oral cavity opening all the time, upper and lower lip then lays respectively at the upper and lower side of second supporting walls 23, described block wall 21 retainings are in the place ahead of tooth, prevent that endoscope (not shown) from making bite-block go deep in the oral cavity when inserting, expansion arm 26 stretches between the tooth and the cheek.Endoscope by insertion groove 12 within the bite-block interpolation entrance cavity, excretory saliva is gathered and is discharged in the through hole 141 of protruding pipe 14 behind the irriate of oral cavity, the vomitus that the intestines and stomach stimulate is produced by endoscope then flows out from exporting 13, thereby prevents vomitus from spraying in the spurting mode and produce pollution.

The above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from this utility model principle; can also carry out some improvement and modification to this utility model, these improvement and modification also fall in the protection domain of this utility model claim.
