Description
Technical Field
The invention belongs to the field of medical disinfection, relates to the concentration of acid electrolysis water in dentistry, and particularly relates to a water supply system and a water supply method for a dentistry comprehensive treatment table.
Background
A dental unit water channel (DUW L) is an important component of a dental unit, and has the main function of providing a water source and providing treatment water for treatment equipment such as a mobile phone, a three-way gun and the like in the treatment process so as to play roles of cooling and flushing.
The DUW L is composed of narrow and long pipes, is easily polluted by bacteria and colonizes and forms a biofilm in the pipes, during treatment, bacterial colonies colonized in the DUW L are often washed away by water flow, the bacteria can enter the oral cavity of a patient along with the water flow, and can also be inhaled into the respiratory tract of the patient or dental medical staff through aerosol generated by an ultrasonic dental scaler and a high-speed turbine handpiece, so that infection occurs, and therefore, the DUW L pollution is considered to be one of important ways to cause dental cross-infection.
In 1963, the pollution of DUW L was first reported by Blake in British dentist, and a great amount of bacteria was found in DUW L. the research shows that the bacteria concentration in the water supply pipeline can reach 2 × 10 after the new oral cavity comprehensive treatment table is connected with the water supply pipeline for one week5CFU/m L, after long-term use, the maximum bacterial concentration can reach 1.0 × 106CFU/mL。
According to the available data, China pays attention to the pollution problem of DUW L s in 2006, and in more than ten years, 28 province/city/district units investigate the waterway pollution condition of the comprehensive dental unit, wherein the investigation range covers 11 provinces of nearly 300 hospitals and more than 1000 dental chairs.
At present, the main reasons for water pollution of the oral cavity comprehensive diagnosis and treatment table are acknowledged, firstly, water source of the oral cavity comprehensive diagnosis and treatment table is not effectively disinfected, secondly, a biomembrane polluted pipeline is easily formed on the waterway wall of the oral cavity comprehensive diagnosis and treatment table, and thirdly, pollution caused by back suction of diagnosis and treatment instruments such as a turbine (a mobile phone) and the like in the operation process is caused. Therefore, solve the key that dentistry integrated treatment platform water route pollutes, firstly get rid of the inside biomembrane of pipeline, secondly last antibacterial to the pipeline.
