Description

A waterway disinfection device for a comprehensive dental treatment table

technical field

The invention relates to the technical field of medical instruments, in particular to a waterway disinfection device for a comprehensive dental treatment table.

Background technique

Dental comprehensive treatment table is the basic equipment for oral diagnosis and treatment. Its modern features are machine chair linkage, complete functions, easy operation, comfortable and beautiful appearance. Early dental chairs were mainly composed of simple wooden seats, while modern dental chairs are composed of hydraulic oil pump chairs and turbines. Its interior includes air system, water system, circuit system and suction system. Due to the small diameter of the water supply pipe and the slow flow of liquid in the water system, exogenous microorganisms are easy to attach to the surface of objects soaked in water, forming a layer of water. Biofilm, which is commonly found on the inner walls of dental chair hoses. However, the water flow in the oral comprehensive treatment table is slow and sometimes in a static state, which provides a good place for the formation of biofilm, and continuously pollutes the waterway environment with the water flow. Even if the dental chair uses distilled water, there is still a risk of biofilm contamination of the pipes. In addition, when the dental handpiece stops, the high-speed turbine handpiece cannot stop immediately under the action of inertia, so an instant negative pressure is generated, and the sewage in the oral cavity is sucked back into the duct of the comprehensive treatment table, causing pollution again.

The existing disinfection method for dental treatment units is to put the configured disinfectant in an independent water storage bucket, connect it to the treatment unit, switch the switch to "water supply from the water tank", then place the pipeline in the bucket or spittoon, and turn it on. Switch to make the disinfectant flow out from each pipeline and rinse the pipeline thoroughly. When the pipeline is full of disinfectant, let the disinfectant stay in each pipeline for 10-20 minutes for disinfection, and finally empty the disinfectant, rinse the pipeline twice with clean water until the clean water flows out of each pipeline for 2-3 minutes. However, the current disinfectant configuration requires staff to pre-configure and adjust manually if the concentration does not meet the needs, which is time-consuming and laborious, and the residual liquid after the disinfectant flushes the pipeline provides a humid growth environment for biofilm. Therefore, there is a potential risk of infection in the waterway system of the comprehensive treatment table, which has become a difficulty in infection control in the process of oral diagnosis and treatment.
