Abstract

The utility model discloses an oral wet-proof device, which is mainly applicable to preventing the affected part from being wet in oral and dentistry treatment as well as expanding the oral operation space. The wet-proof device is formed by a cheek holder and a wet-proof card; the cheek holder is sleeved on the handle of the wet-proof card, and the upper part of the wet-proof card is connected with a wet-proof fork; any of the left fork arm and the right fork arm forms upwards a ridge for blocking the tongue and expanding the curative operation space; moreover, the fork arm is further provided with two pressing reeds which are mainly for clamping wet-proof antiseptic cotton or feeding medicine to the teeth. The utility model has such advantages as perfect wet-proof effect, large oral operation space and long service life as well as being high temperature and high voltage resistant.

Description

The Oral wet-proof device

Technical field: this utility model relates to oral cavity medical apparatus, when particularly relating to dental treatment, is used to prevent that tooth from being got wet by saliva and influence the Oral wet-proof device of therapeutic quality.

Background technology: during at present domestic traditional dental treatment damp proof method be directly with the cotton balls plug in the both sides of being cured the disease tooth, to absorb saliva, also useful gag struts mouth, treats the space to expand; Above-mentioned prior art has following shortcoming: at first be to stop tongue, make the cacodontia can not be well damp proof, influence therapeutic effect; Next is to use gag for a long time, easily makes patient's oral cavity produce tired, very uncomfortable; The 3rd what be that gag adopts is plastics, can not be high temperature resistant, autoclave sterilization, service life be short; The 4th be safety relatively poor, injure tongue easily.

Technology contents: goal of the invention of the present utility model is intended to overcome above-mentioned prior art shortcoming, provide a kind of damp proof effective, working place, oral cavity big, can high temperature high voltage resistant, the Oral wet-proof device of long service life.

Goal of the invention of the present utility model is achieved in that the Oral wet-proof device partly is made up of damp proof card and holder cheek piece two, wherein ask cheek piece to be ligule, be enclosed within damp proof card shank, damp proof card shank bottom is connected with an anti-slip bolt opposite with damp proof card direction, damp proof card handle top is connected with damp proof fork, about also be provided with making leaf spring on two damp proof yokes, making leaf spring is connected on the damp proof yoke that relies on holder cheek piece one side, about in two damp proof yokes any one protuberance is upwards arranged.

Have a strip opening on two yokes about above-mentioned Oral wet-proof device, the position of this opening and making leaf spring is complementary.

The Oral wet-proof device is made by rustless steel.

This utility model compared with prior art has the following advantages:

1, damp proof effective, the dental care working place is big: the Oral wet-proof device blocks dental bed, and the cotton sliver that making leaf spring is being pressed is near cacodontia, and is damp proof effective, and the protuberance side keeping off tongue, and the intraoral therapy working place is increased;

2, owing to use stainless steel material, this Oral wet-proof device high temperature high voltage resistant, long service life.

Description of drawings: Fig. 1 is a structural representation of the present utility model;

The specific embodiment: the Oral wet-proof device partly is made up of for 2 liang damp proof card 1 and holder cheek piece, wherein ask cheek piece 2 to be ligule, be enclosed within 3 ones of damp proof card handles, 3 bottoms of damp proof card handle be connected with one with the opposite anti-slip bolt 5 of damp proof card 1 direction, damp proof card handle 3 tops are connected with damp proof fork 4, about also be provided with making leaf spring 7 on two yokes 6, making leaf spring 7 is connected on the damp proof yoke 6 that relies on holder cheek piece 2 one sides, any one about the Oral wet-proof device in two damp proof yokes 6 upwards has a protuberance 8, have a strip opening 9 on two yokes 6 about above-mentioned Oral wet-proof device, this opening 9 is complementary with the position of making leaf spring 7.
