Problems solved by technology

At present, there is no special sampling tool on the market. Sampling is done by directly taking water from the dental handpiece or removing the handpiece to take water from the interface. Because there are water and gas paths at the same time, it will first cause water splashing, resulting in inaccurate sampling and sample contamination. Secondly, the sampling time is very long and the work efficiency is low. At the same time, it may also cause pollution to the working environment.

Abstract

The invention relates to a sampling tool, in particular to a dental handpiece waterway sampler. The sampler comprises a handle part and a connecting part which are integrally arranged, the connectingpart is provided with external threads, the outer end face of the connecting part is provided with an air inlet, a cooling water port, a cooling air port and an air return port, the air inlet, the cooling air port and the air return port are all blind holes, a sampling opening is formed in the outer end surface of the handle part, and the sampling opening is communicated with the cooling water port. According to the invention, splashing of water during sampling can be avoided, so that inaccurate sampling and sample pollution are avoided; the sampling time is reduced, and the working efficiencyis improved; and a safe and pollution-free working environment is provided for sampling personnel.

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...
