Description

technical field

[0001] The invention relates to a sampling tool, in particular to a dental handpiece waterway sampler, which is used for sampling the water in the handpiece pipeline of a dental comprehensive treatment table. Background technique

[0002] Dental chair tubing consists of narrow, slender pipes that are prone to contamination, leading to biofilm formation. In this way, the pathogenic bacteria in the pipeline of the dental chair can enter the patient's mouth with the water flow, or the aerosol generated by the mobile phone can be inhaled by the patient or medical staff into the respiratory tract, thereby increasing the risk of infection in dental treatment. In addition, there are dead corners in the valve body of dental equipment, which is easy to breed bacteria and form biofilm. If it is not operated for a long time on weekends and holidays, it will lead to the accumulation of biofilm. When it is reused, bacteria and viruses will be released into the water again...

Embodiment Construction

[0018] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0019] As shown in the figure: the dental handpiece waterway sampler includes a handle part 6 and a connecting part 5 which are integrally arranged. The connecting part 5 is provided with an external thread consistent with the thread parameters of the dental handpiece, and the outer end surface of the connecting part 5 is provided with an air inlet 1, a cooling water port 2, a cooling air port 3 and a return air port 4, wherein the air inlet 1 and the cooling air port 3 And air return port 4 are blind holes. A sampling port 7 is provided on the outer end surface of the handle part 6 , and the sampling port 7 communicates with the cooling water port 2 .

[0020] Specifically, for the convenience of operation, an anti-slip surface or anti-slip convex lines are provided outside the handle portion 6, and the anti-slip surface can be in the form of a p...
