The Utility Model Relates to a Branch Salivary Suction Device for Oral Cavity

Background: In the process of dental diagnosis and treatment, a large number of pathogenic microorganisms and aerosols in the mouth of patients are easy to spread into the office, resulting in microbial contamination of the office air. In order to reduce the formation of droplets and aerosols and reduce the dissemination of blood and saliva, negative pressure suction is usually used to reduce most of the aerosols. Objective: In order to reduce the formation of droplets and aerosols and the dissemination of blood and saliva, a branch saliva suction device with both strong and weak suction functions is needed. Methods: A branch saliva suction device with both strong and weak suction functions was designed. Including grip, extension rod, bending pipe, strong straw, pressure sensor, hard pipe, weak straw, sliding block. By inserting a weak straw at the outside of the extension rod, and setting a strong straw at the end of the extension rod, the strong straw and weak straw are combined, so as to improve the applicability of the device and facilitate the user to operate with one hand. By setting a sliding block on the outside of the extension rod, the sliding block can be connected with the outside of the weak straw, and the length of the weak straw can be freely adjusted according to the need, which is convenient to adjust the weak straw, and at the same time, the weak straw can be collected. Results: A branch oral salivary suction device was designed to improve the efficiency of diagnosis and treatment and the comfort of patients. Conclusion: To design a branch saliva suction device for oral use.
