Abstract

An opener. Relates to a medical appliance, in particular to an improvement of a mouth gag for oral clinical treatment. Provides a mouth gag which can synchronously remove spray and aerosol in the process of diagnosis and treatment. The suction tube comprises arc-shaped lips and a suction tube, the arc-shaped lips are arranged on a base in a bilateral symmetry mode, a buckle is arranged on the lower end face of the base, the buckle is clamped on the suction tube, and the suction tube is connected with a suction device. The arc-shaped lips are sent into the oral cavity, the suction apparatus is started, negative pressure is formed in the suction tube, so that negative pressure can be formed in the oral cavity in the operation process of a doctor, aerial fog, spray and the like can be sucked in real time in the dental operation process, particularly, the oral cavity is flushed by using clean water in real time when the dental washing process is needed, water mist can be sucked in real time by using the suction tube with the negative pressure, and pollution caused by splashing of the water mist is prevented.

Description

Mouth gag

Technical Field

The utility model relates to a medical appliance, in particular to an improvement of a mouth gag for oral cavity clinical treatment.

Background

At present, in the oral clinical treatment, in order to facilitate the treatment, an mouth gag is often adopted to help a patient to open the lips. The mouth gag generally comprises arc-shaped oral lip embedded grooves which are arranged in bilateral symmetry and an elastic frame which is connected between the two arc-shaped oral lip embedded grooves in a supporting manner, the elastic frame can force the distance between the two arc-shaped grooves to be reduced, the two arc-shaped grooves can conveniently extend into the oral lip, and then the elastic frame is used for enabling the two arc-shaped grooves to support the oral lip, so that the oral cavity of a patient is in an open state. The existing structure is simpler, and the use is more convenient. However, the individual condition of different patients is different, especially the individual difference between adults and children is more obvious, but the opening angle of the existing opening device can not be adjusted, the opening angle can only be adjusted by the small amplitude of the elasticity of the material, and the opening device can not be used for patients of various ages. In addition, for the department of stomatology, a large amount of aerosol and spray can be formed in the process of diagnosis and treatment, and cross infection is easily caused by close contact between doctors and patients in the process of diagnosis and treatment, so that the spray and the aerosol generated in the process of oral treatment and flushing need to be removed synchronously in the treatment process.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a mouth gag which can synchronously remove spray and aerial fog in the diagnosis and treatment process.

The utility model discloses a following technical scheme realizes: the utility model provides an opener, includes the arc lip and attracts the pipe that bilateral symmetry set up, and is a pair of the arc lip is located on the base, be equipped with the buckle on the lower terminal surface of base, the buckle block is in attract on the pipe, attract pipe and aspirator connection.

The front part of the suction tube is a square tube, and the buckle is clamped on the square tube.

Attract the pipe with the one end of base laminating is equipped with and is used for blockking the spacing platform of buckle, work as the base cover is located when attracting on the pipe, the lateral wall laminating of buckle spacing platform.

One end of the suction tube, which is attached to the base, is provided with a limit groove, and the buckle is clamped in the limit groove.

The back part of the suction tube is a circular tube, and the sectional area of the end part of the square tube extending into the oral cavity is larger than that of the circular tube.

Compared with the prior art, the utility model discloses just starting the aspirator after sending into the oral cavity with arc lip, sub-suction tube forms the negative pressure, like this in doctor operation process, can form the negative pressure in the oral cavity, can absorb aerial fog, droplet etc. in real time at the dental surgery in-process, especially need utilize the water purification to wash the oral cavity often at the tooth washing in-process, utilize the suction tube of negative pressure can absorb water smoke in real time, prevent that water smoke from splashing and causing the pollution.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a side view of FIG. 1;

in the figure: 1. an arc-shaped lip; 2. a suction tube; 3. buckling; 4. a limiting groove.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-2, the mouth gag comprises an arc-shaped mouth lip 1 and a suction tube 2 which are arranged in bilateral symmetry, a pair of the arc-shaped mouth lips 1 are arranged on a base, a buckle 3 is arranged on the lower end surface of the base, the buckle 3 is buckled on the suction tube 2, the suction tube 2 is connected with the suction device, so that when the mouth gag is opened in actual use, negative pressure is generated in the suction tube 2 which is arranged in the mouth, and spray and the like in the flushing process are sucked into the suction tube 2, so that the spray and the like can not splash, and the infection risk is reduced.

The front part of the suction tube 2 is a square tube, and the buckle 3 is clamped on the square tube. The square pipe has the vertically face, and the buckle 3 attracts pipe 2 difficult pine to take off when the block is on square pipe and rotates, and stability is better.

Attract pipe 2 with the one end of base laminating is equipped with and is used for blockking buckle 3's spacing platform, works as the base cover is located when attracting on the pipe 2, buckle 3's lateral wall laminating spacing platform, perhaps attract pipe 2 with the one end of base laminating is equipped with spacing groove 4, buckle 3 block is in the spacing groove 4. Attract pipe 2 to pass through 3 cards of buckle in spacing platform or spacing groove 4, make attract pipe 2 and arc lip 1 can separately produce and pack, the amalgamation is carried forward during the use again, one of them can only need change the pollution part and need not whole set of change when using because of the accident, therefore, the cost is saved, and attract pipe 2 to be able to regard as operating handle at the in-process that arc lip 1 was put into the oral cavity, the doctor does not need the direct contact patient oral cavity when sending into the oral cavity with arc lip 1, but directly send into the oral cavity with arc lip 1 through attracting pipe 2 of cover on the base, consequently, cross infection's risk has been reduced, make whole process of diagnosing more sanitary, safety.

The back part of the suction tube 2 is a circular tube, and the sectional area of the end part of the square tube extending into the oral cavity is larger than that of the circular tube. This makes the partial cross-sectional area of the suction tube 2 in the oral cavity larger, and the efficiency of sucking the droplets higher.

The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention cannot be limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are all within the protection scope of the present invention.
