Individual water storage tanks for dental units

Abstract

The invention provides an independent water storage tank of a dental unit. The independent water storage tank of the dental unit comprises a tank body and a detachable quantitative liquid extraction assembly. The quantitative liquid extraction assembly comprises an outer cover, a liquid extraction pump, an electric push rod and a quantitative liquid containing tank, the liquid extraction pump, the electric push rod and the quantitative liquid containing tank are all arranged inside the outer cover, the outer cover is made of barrel-shaped plastics, an upper threaded port connected with the dental unit is formed in the top of the outer cover, and a lower threaded port connected with the tank body is formed in the bottom of the outer cover; the liquid extraction pump comprises a liquid extraction tank, wherein the liquid extraction tank is internally provided with a lower valve, a piston, an upper valve, a push-pull rod and a connecting rod sequentially from bottom to top. The independent water storage tank of the dental unit can conveniently and rapidly realize quantitative extraction of liquid in the tank on the premise of a low cost, is designed in a detachable mode, is convenient to mount and dismount, and does not affect normal liquid extraction use when dismounted even though the quantitative extraction function is not used.

Description

technical field [0001] The invention relates to an independent water storage tank of a comprehensive dental treatment unit. Background technique [0002] The comprehensive dental treatment table is a necessary medical equipment for dental treatment. It is suitable for the examination, diagnosis and treatment of various dental diseases. It has a complex structure and contains three integrated equipment systems of water, electricity and gas. The waterway system of the dental comprehensive treatment table is composed of a set of narrow and complicated pipes with a diameter of 2~3mm, which are connected to each other. Unique problems such as "back suction", the waterway system is prone to high-density microbial and biofilm pollution during the water supply process (10 5 cfu / ml), if not disinfected regularly, there is a risk of cross-infection. As one of the important parts of the dental unit, the independent water storage tank is mainly used to contain the disinfectant, and to...

AI Technical Summary

Problems solved by technology

During disinfection, the extraction of disinfectant solution is controlled by air pressure, which cannot achieve quantitative extraction of disinfectant solution. When disinfecting pipelines, the staff can only roughly judge the amount of disinfectant solution extracted

Therefore, there is a problem that when the staff judges that the amount of disinfectant is too small, the complete disinfection of the pipeline cannot be realized; when it is judged that the amount of disinfectant is too large, it is not only wasteful, but too much disinfectant may cause corrosion to the pipeline or enter the patient's mouth , there is an iatrogenic risk
