Description

Technical Field

[0001] This utility model relates to the field of comfortable oral treatment technology, and in particular to an automatic saliva-absorbing rubber dam. Background Technology

[0002] In recent years, with the development of oral medicine and the public's increasing attention to oral health, comfort-oriented oral treatment has been widely used. Through effective sedation and pain control, it alleviates the anxiety and discomfort of oral treatment, allowing patients to have a better "three senses" of medical treatment.

[0003] Deep sedation during anesthesia is a central nervous system depression induced by medication, allowing patients to fall asleep peacefully and reducing their responsiveness to external stimuli, thus facilitating various diagnostic and treatment procedures. Sedation includes four levels: mild, moderate, severe, and general anesthesia, each meeting the sedation requirements of different procedures. Among these, moderate to deep sedation is more suitable for adults with fewer teeth in the mouth, shorter treatment cycles, severe tension, anxiety, and fear, as well as children whose parents do not accept general anesthesia. It is the most widely used in clinical practice, allowing patients to truly immerse themselves in a "semi-sleep" dental treatment experience.

[0004] Nevertheless, unlike risk-free sleep, moderate to deep sedation carries risks. However, due to differences in the skill level of dentists and the level of nursing cooperation, as well as incomplete suctioning, the existing oral rubber dam isolation technology may cause oral treatment under moderate to deep sedation to change without any warning, leading to aspiration, respiratory and circulatory depression, and tracheal spasm. Therefore, oral procedures under moderate to deep sedation currently face many challenges, but also a rare opportunity for development. Disposable automatic suction rubber dams can greatly reduce the inflow of blood, water, and material debris into the oral cavity during oral treatment, thus reducing the occurrence of aspiration, respiratory and circulatory depression, and tracheal spasm.

[0005] At the same time, due to the different skill levels and suction abilities of the oral surgery nurses, coupled with the large number of devices operating at the same time, the field of vision is obstructed, which does not allow for a good exposure of the oral surgery field, affecting the oral surgeon's treatment operation and reducing work efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic saliva-absorbing rubber barrier.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a device comprising a rubber barrier body, a filter screen, and a negative pressure suction tube. The rubber barrier body includes an upper cover, a lower cover, a funnel, a rubber barrier, and a rubber hose. The rubber barrier is located at the upper end of the rubber barrier body and has a shape that is high around the edges and low in the center. The lower end of the rubber barrier is connected to the upper cover. Four supporting protrusions symmetrically distributed about the center are connected to the inner side of the upper cover. The filter screen includes a circle, a net bag, and a crossbar. The diameter of the circle is the same as the inner diameter of the lower cover. The filter screen is fixed to the lower cover by the supporting protrusions. A funnel is connected below the lower cover. A rubber hose is provided at the bottom of the funnel, and the end of the rubber hose can be tightly connected to the negative pressure suction tube.

[0008] Preferably, the upper ring cover is provided with a plurality of fixing members B, and the lower ring cover is provided with a plurality of fixing members A.

[0009] Preferably, the fastener A corresponds to the fastener B.

[0010] Preferably, the inner side of the lower ring cover is connected to four support protrusions that are symmetrically distributed about the center.

[0011] Preferably, a rubber hose is provided at the lower end of the funnel.

[0012] Preferably, the filter screen can be placed in the funnel.

[0013] Preferably, the filter screen is provided with a crossbar with weak magnetism.

[0014] Compared with existing technologies, the advantages of this invention are as follows: This invention has a simple structure, requires fewer operating devices, and can effectively expose the oral cavity operating field, improving the efficiency of oral diagnosis and treatment. Furthermore, it eliminates the need for nursing assistance and saliva suction, reducing manual operation. It can automatically collect blood, water, and material debris generated during oral treatment, preventing these substances from entering the patient's mouth and causing aspiration, respiratory or circulatory depression, or bronchospasm.

Detailed Implementation

[0021] To provide a better understanding of the purpose, structure, features, and functions of this utility model, detailed descriptions are provided below with reference to specific embodiments.

[0022] Please see Figure 1-5 One embodiment of this utility model includes a rubber barrier body 1, a filter screen 2, and a negative pressure suction tube 3. The rubber barrier body 1 includes an upper ring cover 108, a lower ring cover 101, a funnel 103, a rubber barrier 107, and a rubber hose 104. The rubber barrier 107 is located at the upper end of the rubber barrier body 1 and has a shape that is high around the edges and low in the center. The lower end of the rubber barrier 107 is connected to the upper ring cover 108. The inner side of the upper ring cover 108 is connected to four support protrusions 102 that are symmetrically distributed about the center. The filter screen 2 includes a circle 203, a net bag 202, and a crossbar 201. The diameter of the circle 203 is the same as the inner diameter of the lower ring cover 101. The filter screen 2 is fixed to the lower ring cover 101 by the support protrusions 102. A funnel 103 is connected to the lower ring cover 101. A rubber hose 104 is provided at the bottom of the funnel 103. The end of the rubber hose 104 can be tightly connected to the negative pressure suction tube 3.

[0023] Preferably, the upper ring cover 108 is provided with a plurality of fixing members B106, and the lower ring cover 101 is provided with a plurality of fixing members A105.

[0024] Preferably, the fastener A105 corresponds to the fastener B106.

[0025] Preferably, the inner side of the lower ring cover 101 is connected to four support protrusions 102 that are symmetrically distributed about the center.

[0026] Preferably, a rubber hose 104 is provided at the lower end of the funnel 103.

[0027] Preferably, the filter screen 2 is placed in the funnel 103.

[0028] Preferably, the filter screen 2 is provided with a crossbar 201 with weak magnetism.

[0029] In use, remove the original automatic saliva-absorbing rubber dam. Secure the lower cover 101 and upper cover 108 to the dam using fasteners A105 and B106. Fix the filter 2 in the funnel 103 using the support protrusion 102. The crossbar 201, being weakly magnetic, not only helps secure the filter 2 to the funnel but also allows the doctor to easily remove it with tweezers, thus removing the collected material debris without clogging the rubber tubing 104. After the dental treatment is completed, open the negative pressure suction tube 3 to collect the saliva, blood, and water from the funnel 103 into a dedicated container. This invention is also reusable; it only requires high-pressure sterilization.

[0030] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
