Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical supplies technology, and in particular to a water-absorbing oral rubber dam. Background Technology
[0002] During oral surgery, a rubber dam is often used. Its main purpose is to isolate the treatment area, prevent oral fluids from interfering with dental procedures, and protect the patient's airway. This device is typically made of soft rubber and is fixed inside the patient's mouth in a specific way to effectively cover the treatment area.
[0003] A typical oral rubber dam consists of a rubber dam membrane, a connecting frame, and drainage holes. By firmly fixing the rubber dam membrane inside the patient's mouth, the oral rubber dam can effectively isolate the treatment area and prevent saliva and other liquids from interfering with the doctor's operation.
[0004] However, during surgery, some procedures often lack effective fluid drainage mechanisms, leading to fluid accumulation in the oral cavity and affecting the surgeon's field of vision and treatment outcomes. When fluid is not drained in time, it not only increases patient discomfort but also leads to accidental aspiration, thus compromising treatment safety. Therefore, a water-absorbing oral rubber dam is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this invention provides a water-absorbing oral rubber barrier, which aims to improve the problem of liquid accumulation in the oral cavity during operation of some existing devices.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A water-absorbing oral rubber dam includes a frame, a bottom rubber dam fixedly connected to the bottom of the frame, a plurality of tooth positioning sleeves fixedly connected to the bottom of the bottom rubber dam, a top rubber dam fixedly connected to the top of the frame, a plurality of drainage holes opened on the top of the top rubber dam, a drainage tube fixedly connected inside the bottom rubber dam, and a suction tube fixedly connected outside the drainage tube.
[0008] As a further description of the above technical solution:
[0009] The tooth positioning sleeve is evenly distributed on both sides of multiple bottom rubber barriers. It is cone-shaped and hollow inside, with its bottom opening at the top of the top rubber barrier.
[0010] As a further description of the above technical solution:
[0011] The external of the flow guide holes is distributed on the top of the top layer rubber barrier, and the external of the multiple flow guide holes is distributed around the multiple top layer rubber barriers.
[0012] As a further description of the above technical solution:
[0013] The outside of the suction tube is between the bottom rubber barrier and the top rubber barrier;
[0014] As a further description of the above technical solution:
[0015] The exterior of the plurality of flow guide holes is at the top of the bottom rubber barrier, while the exterior of the suction tube is at the bottom of the plurality of flow guide holes;
[0016] As a further description of the above technical solution:
[0017] Multiple drainage holes guide all the liquid from the top of the top rubber barrier into the inner bottom wall of the bottom rubber barrier, allowing the drainage tube to draw it out.
[0018] This utility model has the following beneficial effects:
[0019] In this invention, the combination of a double-layered rubber dam and a drainage hole facilitates the suction of fluids from inside the oral cavity through a drainage tube during treatment. This design improves the dryness and operational visibility during oral treatment, reduces patient discomfort, and helps enhance the safety and efficiency of dental treatment, ensuring that doctors can operate in a clear and comfortable environment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figures 1 to 4 This utility model provides an embodiment of a water-absorbing oral rubber dam, including a fixation frame 1, whose main support structure is a bottom rubber dam 2 fixedly connected to the bottom of the fixation frame 1, which directly contacts the patient's oral cavity. Multiple tooth positioning sleeves 3 are fixedly connected to the bottom of the bottom rubber dam 2. By shortening the tip of the tooth positioning sleeve 3, it can be fitted onto the outside of the teeth. A top rubber dam 4 is fixedly connected to the top of the fixation frame 1. Multiple drainage holes 5 are opened on the top of the top rubber dam 4. Its design allows saliva and other liquids to be effectively drained through the drainage holes 5 in various dental treatments, keeping the operating area dry. A drainage tube 6 is fixedly connected inside the bottom rubber dam 2, allowing liquids to flow into the inner bottom wall of the bottom rubber dam 2. The bottom rubber dam 2 allows all liquids to flow to the drainage tube 6. A suction tube 7 is fixedly connected to the outside of the drainage tube 6. The design of the suction tube 7 can conveniently prevent blockage of the hollow opening when pressure is applied.
[0028] The tooth positioning sleeve 3 is evenly distributed on both sides of multiple bottom rubber barriers 2. It is conical in shape and hollow inside. Its bottom is opened on the top of the top rubber barrier 4. The external of the drainage holes 5 is distributed on the top of the top rubber barrier 4. The external of the multiple drainage holes 5 is distributed around the multiple top rubber barriers 4. The external of the suction tube 7 is between the bottom rubber barriers 2 and the top rubber barriers 4. The external of the suction tube 7 is at the bottom of the multiple drainage holes 5. The multiple drainage holes 5 guide the liquid remaining on the top of the top rubber barrier 4 into the inner bottom wall of the bottom rubber barrier 2, so that the drainage tube 6 can suck it out.
[0029] Working Principle: First, an absorbent oral rubber dam is placed in the patient's mouth. The bottom rubber dam 2 is then secured tightly to the teeth and soft tissues using a fixation frame 1, ensuring a good seal. Multiple conical tooth positioning sleeves 3 beneath the bottom rubber dam 2 can be trimmed to the appropriate point to effectively cover specific teeth, further increasing the seal and support. At this time, the patient's saliva and other biological fluids accumulate on the surface of the top rubber dam 4 due to gravity. To keep the treatment area dry, multiple drainage holes 5 at the top of the top rubber dam 4 begin to function, quickly guiding the fluid into the dam's interior. The fluid flows into the bottom rubber dam 2 through the drainage holes 5 and is then drawn into the internal suction tube 7 through the hollow structure between the bottom and top rubber dams, ensuring all fluid flows along the appropriate drainage path. The drainage tube 6 connects to the suction tube 7, effectively draining the fluid through negative pressure, preventing blockage of the hollow opening under pressure, thus improving the safety and comfort of dental treatment.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
