Description

An isolation device used to isolate droplet transmission during oral treatment

technical field

The invention belongs to the technical field of dental medical instruments, in particular to an isolation device used to isolate the spread of droplets during oral treatment.

Background technique

During the dental treatment, the high-speed turbine cuts the teeth after cooling by spraying water in the mouth, but at the same time, the splashing liquid mixes with the patient's saliva, which will produce a large amount of droplets and aerosols. However, during the treatment, the patient's mouth and nose are always kept open. state, direct exposure to the clinic environment, these constitute possible routes for the spread of infectious diseases, especially during outbreaks of respiratory infectious diseases, a device is needed that can effectively isolate patients from exposure to splashing liquids.

In addition, various disinfectant solutions are often used in dental treatment. Some high-concentration disinfectant solutions, such as the commonly used 5% sodium hypochlorite solution, are highly irritating to tissues. If they accidentally touch the skin or mucous membranes of patients, especially the eyes conjunctiva, can cause serious injury.

In the existing dental treatment process, rubber dam isolation is often used. A piece of elastic rubber membrane is used to isolate the position of the tooth as needed. Small holes are punched in the membrane to cover the affected tooth, and the elastic neck of the rubber dam is used to tighten the neck of the tooth. , to isolate it from the oral environment. However, the facebow used in rubber dam isolation is smaller, only the oral cavity is isolated, and the patient's nose and face are still exposed to the outside. A large number of droplets and aerosols in the clinic can still be inhaled during breathing. In addition, the patient's face and face have not been effectively isolated, all of which pose potential safety hazards.

SUMMARY OF THE INVENTION

In order to solve the above problems existing in the prior art, the purpose of the present invention is to provide an isolation device for preventing the spread of droplets during oral treatment, providing comprehensive protection and helping the patient's nasal cavity and conjunctiva to avoid exposure to dental treatment surroundings.

To achieve the above object, the present invention provides the following technical solutions:

An isolation device for preventing the spread of droplets during oral treatment, comprising an inner ring facebow that fits on the outer periphery of the oral cavity and an outer ring facebow that shields the face, the inner ring facebow and the outer ring facebow are closed by a blanket The connection forms a trumpet-shaped structure; the upper part of the outer ring face bow is connected with a bracket assembly that supports the nose space.

Further, the inner ring facebow is used for placing the finished rubber dam facebow, and the diameter of the inner ring facebow is smaller than that of the finished rubber dam facebow.

Further, the bracket components are two headband strips respectively arranged on both ends of the outer ring face bow.

Further, a plurality of anti-skid protrusions are densely distributed on the inner wall of the headband strip.

Further, the bracket components are two bendable metal wires respectively arranged on both ends of the outer ring face bow.

Further, the outer periphery of the bendable metal wire is wrapped with a non-slip casing.

Beneficial effect: The present invention provides an isolation device for preventing the spread of droplets during oral treatment. The device can ensure that the affected teeth in dental treatment are completely isolated from the oral cavity and face of the patient, and effectively prevent the liquid during the treatment from contacting the patient. At the same time, the patient breathes through the nose during the treatment process, instead of directly inhaling the droplets splashed during the treatment process. Under the condition of cooperating with the fresh air system, the inhalation of the aerosol contaminated by the treatment in the clinic can also be avoided. . Even during the outbreak of respiratory infectious diseases, the effective isolation and protection of patients can be guaranteed without hindering the treatment of oral diseases. Therefore, the device is suitable for general use in dental treatment.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The present invention will be further described below with reference to the accompanying drawings.

An isolation device for isolating droplet transmission during oral treatment, comprising an inner ring facebow 1 that fits on the periphery of the oral cavity and an outer ring facebow 2 that shields the face, the inner ring facebow 1 and the outer ring facebow 2 A trumpet-shaped structure is formed by closed connection of the blanket 3; the upper part of the outer ring facebow 2 is connected with a bracket assembly that supports the nasal space, so as to ensure smooth breathing of the patient.

The inner ring facebow 1 is used to place the finished rubber dam facebow, and the diameter of the inner ring facebow 1 is smaller than that of the finished rubber dam facebow, and the elasticity of the rubber dam 3 is utilized to make the finished rubber dam facebow adhere to the rubber. On the cloth to make it close to the inner ring face bow 1.

As an embodiment, the bracket components are two headband strips 4 respectively disposed on both ends of the outer ring face bow 2. The inner wall of the headband strips 4 is densely covered with a plurality of anti-skid protrusions. By adjusting the headband strips 4. The nose space can be supported at the front and rear positions of the head, and the anti-slip bumps make the headband more firmly fixed on the head.

As another embodiment, the bracket components are two bendable metal wires 5 respectively disposed at both ends of the outer ring face bow 2. The bendable metal wires can use their toughness to support the nose space and use its The bendability is convenient for fixing on the head, adjusting the wearing position, and wrapping and locking the ends of the two bendable wires 5 to fix the device. The outer periphery of the bendable metal wire 5 can be wrapped with a non-slip casing to make the fixing more firm, and the material of the anti-skid casing can be rubber, plastic or cloth.

The working principle of the device is as follows: the inner ring facebow of the device is placed outside the patient's mouth, and the finished rubber dam facebow is placed on the inner ring facebow to isolate the affected teeth, and the finished rubber dam facebow and the inner ring are separated by the elasticity of the blanket. The facebow is kept close, and the device is worn on the patient's head through the bracket assembly. By adjusting the wearing position, the nasal space is propped up to ensure the patient's breathing is smooth. The blanket between the inner and outer rings covers the patient's face to isolate it from the treatment space, so as to achieve the effect of isolating the spread of droplets during oral treatment.
