In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1

As shown in fig. 1 to 7, the oral cavity miniature dam 2 is a new concept proposed by the prior art of a square-shaped oral cavity covering dam, and in the present embodiment, the miniature dam only shields the teeth to be treated, thereby playing a role of shielding.

The miniature rubber dam comprises a fixing part and a sealing part. The fixing portion includes a dam 21 and an A-ring 22, and the sealing portion includes a B-ring 23 and a C-ring 24. The rubber barrier film 21 is arc-shaped, the edge of the rubber barrier film 21 is fixedly connected with the ring A22 in a circle, and specifically, the ring A22 and the rubber barrier film 21 are integrally formed and made of the same material and are the neck of the rubber barrier film 21. The detachable connection of the fixing part and the sealing part is realized through the detachable connection of the A ring 22 and the B ring 23. The size of the ring A is slightly smaller than that of the ring B, so that the ring A can be conveniently and tightly sleeved on the ring B, and the neck part is expanded after being supported by the ring B.

The B ring 23 and the C ring 24 are connected in a foldable manner, the B ring 23 and the C ring 24 are made of magnetic materials, and the B ring 23 and the C ring 24 can be stably folded and overlapped together through the magnetic action. But the magnetic force between them should ensure that it can be opened under the intervention of external force from human hand.

A downward extending sleeving table 231 is arranged on one side of the B ring 23 for connecting with the A ring 22, so that the A ring 22 is sleeved on the downward extending sleeving table. The B-ring 23 is provided with a safety tape 25 crossing the radial line of the B-ring 23, and the B-ring 23 is further provided with a tape hook 26 for hanging the mounting tape crossing the radial line of the B-ring 23 to the edge of the B-ring 23 so as not to interfere with the central part of the B-ring 23. A transparent film 27 is arranged in the C ring 24 to shield the central hollow part of the C ring 24.

Further, the side of the B ring 23 folded and overlapped with the C ring 24 and the side of the C ring 24 folded and overlapped with the B ring 23 are respectively provided with a mutually matched ring groove 232 and a ring protrusion 241 for positioning.

The use method of the miniature rubber dam is as follows:

firstly, marking a position on the rubber barrier film 21 by using special perforating pliers to perforate (generally perforating at the center of the rubber barrier film), then perforating a small hole by using butterfly pliers, clamping the hole on the neck of a patient tooth to be treated, sleeving the rubber barrier film 21 on the rubber barrier film, and taking off the butterfly pliers, wherein the rubber barrier film 21 is sleeved on the patient tooth at the moment (if the patient is not filled with the medicine, only the step is needed);

secondly, the A ring 22 on the rubber barrier film 21 is sleeved on the B ring 23, so that the fixed part and the sealing part are connected together in the oral cavity;

thirdly, the safety adhesive tape 25 can penetrate through the safety belt to insert the needle when the myelination nerve of the tooth is manually extracted or various needles are manually operated, so that the medical accident caused by the fact that the needle falls into the throat in the mouth is prevented (if the needle is not required to be inserted, the safety adhesive tape 25 is hung on the adhesive tape hook 26);

fourthly, when the situations of medicine application, mouth rinsing and the like are needed and the affected tooth needs to be sealed, the C ring 24 is folded, so that the B ring 23 is connected with the C ring 24 by magnetic force to form sealing, and the C ring 24 is provided with a transparent film 27 to ensure that the liquid medicine of the affected tooth does not leak out, and prevent the liquid medicine from flowing into the mouth and burning the gum; during the treatment process, when a patient needs to spit or gargle, the affected teeth which are washed or applied with the liquid medicine can be sealed to prevent bacteria from entering the root canal to cause infection; the most easily occurring situation in dental filling or aesthetic restoration is that the teeth being restored are wetted by the saliva of the patient, and water is introduced, thus directly influencing the restoration or treatment effect; in order to prevent the condition that the mouth water wets the working teeth in the prior art, the cotton sand ball is used for moisture insulation, and the micro rubber dam is used for processing to directly seal the affected teeth, so that the cost is saved, the working efficiency is improved, and the repairing or curing rate is high.

Example 2

The difference between this embodiment and embodiment 1 is that the size of the oral cavity miniature dam 2 is increased, that is, the size is designed to be slightly larger, so that the auxiliary treatment of several adjacent affected teeth can be realized, and the installation method is still as described above.

According to the above embodiment, alright realize the utility model discloses well. It is worth to say that, on the premise of the above structural design, in order to solve the same technical problem, even if some insubstantial changes or retouching are made in the utility model, the essence of the adopted technical scheme is still the same as the utility model, so it should be in the protection scope of the utility model.
