Abstract

The utility model relates to the technical field of medical instruments, in particular to a gasbag-type mouth cushion, which consists of a gasbag (1), a mouth cushion plate (2), an inflation tube (3) and an inflation valve (4). The gasbag (1) after inflation is in a tubular shape, and a tube cavity of the gasbag is similar to an inner cavity of a mouth cushion body of the prior mouth cushion; the mouth cushion plate (2) is attached to the upper and lower walls of an inner cavity of the gasbag, so as to play a role in fixing form and protecting the wall of the gasbag; the outer wall of the inflated gasbag is in a dumbbell shape, but a front gasbag (1.1) is bigger than a back gasbag (1.2); the front gasbag (1.1) is equivalent to a fixed wing of the prior mouth cushion, and covers lips to play a role in fixing; the back gasbag is placed into a mouth, and teeth or gums bite a sunken part between the front gasbag and the back gasbag, which can prevent the mouth cushion from sliding into or out from an oral cavity; and the inflation tube (3) and the inflation valve (4) are used for inflating or deflating the gasbag. The mouth cushion has the advantages that the mouth cushion can be folded, and is convenient to store, carry and insert into the mouth; the wall of the gasbag is smooth and soft without causing injury to the gums; and the mouth cushion is especially suitable for the old, children, people with exposed gums or people in unconsciousness.

Description

A kind of inflated type mouth pad

Technical field

This utility model relates to technical field of medical instruments, is a kind of inflated type mouth pad that patient such as oral intubation uses.

Background technology

Clinically, use a mouthful pad to make patient's the open-shaped attitude in oral cavity check or treat very general.As in inserting scope and whole checking process, need face to be strutted and make the front tooth can not interlock scope shank, and in art, need to suffocate to avoid the patient with sputum aspirator tube sucking-off secretions in the patient oral cavity continuously with the mouth pad; And for example the tracheal intubation patient for preventing that endotracheal tube is snapped flat reaching and carries out pars oralis pharyngis suction expectorant at any time, also need place a mouthful pad.Common mouth pad is made by duroplasts, divides mouthful pad and fixed-wing two parts, mouthful pad in a tubular form, the cross section be an ellipse, an end and fixed-wing join, the other end mouth of pipe has an edge, in case slippage during the front tooth interlock; Fixed-wing is the dome shape depression, middle opening, and this opening docks at concave face with the mouth of pipe of mouthful pad, and it covers on lip and plays fixation outward.Yet because the mouth pad quality of using at present is harder, volume is relatively large, acquire a certain degree of difficulty when inserting, and particularly old man, child or obnubilation person, they can not cooperate with on one's own initiative face is opened enough greatly; Also often have sense of discomfort, particularly old man, child or gingiva to expose the person after inserting, the harder mouth pad of quality might cause damage to gingiva.

Summary of the invention

The purpose of this utility model provide a kind of easy to use, to insert the back comfortable and can not cause the inflated type mouth pad of damage to gingiva.

This utility model is made up of mouth backing plate, air bag, gas tube and charge valve.Behind the airbag aeration in a tubular form, inner chamber is identical with the mouth pad inner chamber of existing mouthful of pad, be flat tubulose, the cross section is like rectangle or ellipse, and mouthful backing plate matter is hard, is attached at two walls up and down of air bag inner chamber, its shape sizableness is two walls about existing mouthful pad, the mouth backing plate works to support setting and protection airbag wall, prevents the wearing and tearing of intubate to airbag wall, and the airbag wall height of the air bag left and right sides is equivalent to the left and right sides of existing mouth pad; Gasbag ektexine after the inflation is dumbbell shaped, but preceding air bag is greater than rear gasbag, and preceding air cell covering plays fixation outside lip, the fixed-wing that is equivalent to existing mouthful of pad, in the rear gasbag posting port, tooth or gingiva are stung the recess between the pro-rear gasbag, can prevent that the seam pad slips into or skid off the oral cavity; Gas tube one end is connected in preceding air bag, and the other end is connected in charge valve, is used for to airbag aeration or venting.

During use, gas in the air bag is discharged, this utility model is folded state, utilize the hardness of mouthful backing plate rear gasbag one end to be inserted in slight open mouthful earlier, the reuse charge valve is given airbag aeration by gas tube, and the oral cavity is gradually strutted, fully open until air bag and to reach reservation shape, before air cell covering outside lip, tooth or gingiva are stung the recess between the pro-rear gasbag, then just can be routinely tube chamber by air bag carry out operations such as intubate.With finishing, the gas in the air bag is bled off, extraction gets final product.

This utility model is easy to use, and the airbag wall smooth pliable is pleasant in the posting port, is specially adapted to old man, child, the exposed person of gingiva or obnubilation person.This utility model can fold, and both has been convenient to insert in the mouth, also is convenient to store and carry.
