Dental high-speed turbine handpiece anti-back-suction effect detection device and detection method

Abstract

The invention discloses a dental high-speed turbine handpiece anti-back-suction effect detection device and detection method.The dental high-speed turbine handpiece anti-back-suction effect detection device comprises a supporting mechanism, a handpiece power mechanism, an environment simulation mechanism and a sample collection device used for collecting back-suction gas, the supporting mechanism comprises a base table and a supporting rod, and the supporting rod is fixedly connected to the upper surface of the base table; and the mobile phone power mechanism comprises an air pump and an electronic valve capable of automatically controlling an air flow switch according to a preset condition. Tooth debris and the like exist in the working environment in the form of aerosol, the environment simulation mechanism is arranged to simulate the environment containing ground tooth powder in the oral cavity of the working environment, the stirring mechanism is arranged in the cavity, and the stirring mechanism rotates to drive air in the cavity to flow, so that the tooth debris can be ground in the working environment. Particle powder, microorganisms and water vapor in the cavity are uniformly suspended in the cavity, and the working environment of the dental high-speed turbine handpiece in the oral cavity can be simulated.

Description

technical field [0001] The invention relates to the technical field of equipment detection, in particular to a device and a detection method for the anti-suction effect of a dental high-speed turbine handpiece. Background technique [0002] Dental high-speed turbine handpieces are in close contact with patients' saliva, blood, gingival crevicular fluid and plaque during dental treatment. The surface of the handpiece and the turbine components and pipes inside the handpiece may be exposed to different degrees of pathogenic microorganisms after use. In the process of dental diagnosis and treatment, mucous membrane and skin damage are generally caused. Many blood-borne and infectious diseases are transmitted through contact with wounds of dental high-speed turbine handpieces that are not strictly sterilized. The dental high-speed turbine handpiece is precisely manufactured and has a complex structure. The turbine cavity, water and air passages and other accessories in the handp...

AI Technical Summary

Problems solved by technology

[0004] Existing dental high-speed turbine handpieces generally have anti-suckback functions. However, it is generally difficult for dentists to detect the anti-suckback effect of handpieces clinically. The head of the mobile phone is immersed in the bacterial culture solution, and it is repeatedly rotated and stopped. Finally, it is found that the number of bacterial CFUs in the air pipe port of the anti-suckback mobile phone and inside the mobile phone is significantly lower than that of ordinary turbine mobile phones. However, in the evaluation methods of the existing technology, The mobile phone is completely immersed in the bacterial culture solution or other solutions, which is far from the real environment when the mobile phone is working. The evaluation is not objective and lacks accuracy.

[0005] However, other existing dental high-speed turbine handpiece anti-suckback effect evaluation devices and methods can only simulate the suckback process, but cannot simulate the environment inside the oral cavity, resulting in inaccurate detection and evaluation, and the inability to strictly control the suckback pollution.
