Description

Mouth isolation set

technical field

The utility model relates to an oral cavity isolation sleeve, which belongs to the technical field of medical instruments.

Background technique

The saliva suction device that is widely used in oral cavity clinics can not effectively absorb the waste and waste liquid produced in the treatment process. The above waste and waste liquid will cause discomfort in the patient's throat and cause retching and other reactions in the patient, which not only brings pain to the patient, Moreover, the operation is often interrupted because of the patient's retching reaction, resulting in prolonged treatment time. With the emphasis on this problem, the rubber dam technology has recently emerged. This technology uses a rubber membrane of a special material to attach to the oral cavity, and the part that needs to be treated is opened in the corresponding part of the rubber membrane to facilitate the operation. Other parts are covered by the rubber membrane. Covered, so the waste and liquid generated during the operation will not flow into the throat of the patient, and will not cause discomfort in the throat of the patient, but because it is made of special materials, the cost is high, and the use process is cumbersome, so it cannot be widely popularized .

Contents of the invention

The utility model aims at the deficiencies of the prior art, and provides an oral isolation sleeve with low cost and easy operation.

The oral isolation sleeve is composed of an inner isolation surface, an outer isolation surface, an inner attachment ring and an outer attachment ring; the inner isolation surface is a membranous structure, and the edge of the inner isolation surface is fixedly connected with the inner attachment ring; the outer isolation surface is provided with a non-membrane The membrane structure of the area, the inner membrane edge of the outer isolation surface is fixed with the outer attachment ring; the inner attachment ring and the outer attachment ring are folded and opened along the horizontal line where the center of the ring is located, and the folding and bending between the inner attachment ring and the outer attachment ring There is a gap between the inner attachment ring and the outer attachment ring. When the attachment ring joint is used, it is located in the edentulous area behind the gums. It can keep the inner attachment ring and the outer attachment ring open and closed to a certain extent, so that the patient can maintain a passive mouth opening during the treatment process, and reduce the fatigue of the patient's active mouth opening during the operation. degree.

An occlusal block is arranged at the gap 1-4cm away from the attachment ring joint.

A lip supporter is arranged on the outer attachment ring.

The lip support is a sheet-like structure extending outside the attachment ring. The lip supporter is attached to the outer attachment ring by incomplete riveting, which can prevent the lip supporter from rotating around the outer attachment ring, and can adjust its position change according to the needs of the treatment position. The lip supporter can move the upper and lower lips Separation from teeth and gums.

Adhesive lining A is arranged on the outer side of the inner attachment ring, and adhesive lining B is arranged on the inner side of the outer attachment ring. The adhesive lining is made of soft oral material, and after being squeezed, it can fill the gap between the inner attachment ring, the outer attachment ring and the teeth, so as to ensure the isolation effect of the isolation sleeve.

The outer side of the outer isolation surface at the folding and bending part of the outer attachment ring is connected with a buccal isolation surface.

The inner attachment ring and the outer attachment ring can be made of organic polymers such as resin and have certain hardness. The functions are: (1) provide attachments for the isolation surface; (2) the outer attachment ring acts as an attachment for the lip supporter; (3) can disperse the pressure of the contact point of the lip supporter; (4) better adhere to the oral tissue Fit, well fixed in the oral cavity and smooth edges, comfortable and safe.

During the operation, only the upper and lower teeth are exposed outside the isolation sleeve through the use of the oral isolation sleeve, providing a relatively independent space for the operation. The inner isolation surface can effectively protect the oral mucosa, avoid damage to the oral mucosa during dental treatment, and waste generated during the treatment (such substances may be harmful to the body and may be a source of allergies for some patients) in the oral mucosa The attachment on the upper surface makes the patient feel uncomfortable; in addition, the oral cavity isolation sleeve can also reduce the secretion of some salivary glands in the oral cavity. The waste and waste liquid generated during the operation is directly stored in the bag formed by the inner isolation surface, the teeth and the outer isolation surface, avoiding the throat discomfort caused by the above waste and waste liquid, and preventing them from entering the digestive tract, reducing the removal during treatment The frequency and effect of solid and liquid waste, while speeding up the surgical process. The use of the occlusal block can reduce the fatigue of the patient's active mouth opening for a long time, and make the patient more comfortable during the treatment process. The device can make the whole operation process more safe, convenient, comfortable and humanized.

Detailed ways

The utility model will be further described below in conjunction with the embodiments, but the protection scope of the utility model is not limited thereto.

Example 1

The oral cavity isolation sleeve is composed of an inner isolation surface 1, an outer isolation surface 2, an inner attachment ring 3 and an outer attachment ring 4; the inner isolation surface 1 is a membrane structure, and the edge of the inner isolation surface 1 is fixedly connected with the inner attachment ring 3; The isolation surface 2 is a membranous structure provided with a membrane-free area, and the inner membrane edge of the outer isolation surface 2 is fixed with an outer attachment ring 4; the inner attachment ring 3 and the outer attachment ring 4 are folded and opened along the horizontal line where the center of the ring is located, and the inner attachment ring 4 is folded and opened. The folds and bends between the attachment ring 3 and the outer attachment ring 4 are fixedly connected by the attachment ring joint 5 , and there is a gap 6 between the inner attachment ring 3 and the outer attachment ring 4 . There are occlusal blocks 7 that are flexibly connected at 6 places of gaps in the range of 5 1-4cm from the attachment ring joint. A buccal isolation surface 11 is connected to the outer side of the outer isolation surface 2 at the folding and bending part of the outer attachment ring 4 .

When in use, the teeth are first inserted into the gap between the inner attachment ring and the outer attachment ring, and then the inner isolation surface and the outer isolation surface are attached to the corresponding mucous membranes of each part of the oral cavity.

According to the actual clinical test, using the product of the utility model for surgery does not require saliva suction operation, which greatly shortens the treatment time, and the cost of using this product is significantly lower than that of the rubber dam technique. Due to the use of ordinary medical materials, the cost can be controlled within ten The rubber dam technology uses special materials, and the production cost is much higher than this product.
