A dental chair waterway disinfection system and method

technical field

The present application relates to the field of dental equipment, in particular to a waterway disinfection system and method for a dental chair.

Background technique

The full name of the dental chair is the comprehensive dental treatment table, which is the equipment and operating table for the dentist to carry out examination and treatment. The waterway of the dental comprehensive treatment table is an important part of the dental chair, which includes the dental handpiece on the dental chair, the three-purpose gun, the three-purpose gun in the assistant's position, the treatment water for equipment such as dental scalers, and the patient's mouthwash water.

After long-term use, the water pipes of the dental unit are easily polluted by bacteria, and bacteria colonize and form biofilms in it. During the treatment process, the bacteria colonized in the pipeline are often washed down by the water flow. These bacteria can enter the patient's mouth with the water flow, and can also be inhaled by the patient or dental staff through the aerosol generated by the ultrasonic scaler and high-speed turbine handpiece. respiratory tract, leading to infection. Therefore, the waterway of the dental chair needs to be independently and regularly disinfected to control the pollution in the waterway pipeline.

In view of the above-mentioned related technologies, the inventor found that the water supply pipe network of dental chairs in many hospitals is unreasonably set up. Some use municipal tap water sources for direct water supply, and some are connected to the central pure water treatment system for centralized water supply. However, this is necessary for independent regular water supply. It is quite inconvenient to sterilize the dental chair waterway; at the same time, if the water supply network is changed, it involves not only the dental water supply, but also the water supply network of the entire hospital, which requires a lot of time, energy and expense, so many Hospitals have not found an effective and convenient waterway disinfection method for dental chairs.
