Description

Technical Field

[0001] The invention relates to the technical field of medical instruments, and in particular to an external dental handpiece water supply system. Background Art

[0002] The dental comprehensive treatment table is an indispensable device in dental diagnosis and treatment. Its built-in water system provides water for dental handpieces, three-way guns and other instruments. However, the pollution problem of the water system of the dental comprehensive treatment table has always been a focus of attention at home and abroad. Existing studies have shown that the main reason for water pollution is that the input water source itself may contain planktonic microorganisms. At the same time, during the diagnosis and treatment process, when the dental handpiece stops rotating, it will negatively suck back the saliva and blood in the patient's mouth, sucking the microorganisms into the water pipe. These microorganisms are deposited and attached to the inner wall of the water pipe lumen, quickly forming a biofilm, causing serious pollution of the water system. The contaminated water system may directly enter the patient's mouth through the treatment water, or indirectly spread through aerosols, bringing potential infection risks to patients and medical staff. Especially in surgical operations such as surgical tooth extraction that require the use of high-speed handpieces, the water quality of the treatment water is directly related to the risk of postoperative infection in patients. Therefore, for operations such as surgical tooth extraction that have high water quality requirements, it is recommended to use treatment water that meets the standards of drinking water, or even sterile water. However, the water quality of the built-in water system of the comprehensive oral treatment unit is often difficult to meet the above standards in a long-term and stable manner, and long-term and frequent disinfection must be carried out to reduce the risk of contamination.

[0003] In the prior art, independent water sources, filtration devices or regular disinfection are usually used to address the problem of water contamination in comprehensive oral treatment tables, but these methods have obvious shortcomings. Although frequent disinfection of built-in water channels can reduce the risk of contamination, long-term use may cause microorganisms in the water channels to develop drug resistance, which is not conducive to hospital infection control. At the same time, the maintenance and disinfection of built-in water channels require a lot of time and energy, which increases the workload of medical staff and is difficult to completely avoid contamination problems. In addition, it is difficult for the built-in water channel system to meet the needs of different diagnosis and treatment scenarios at the same time. Ordinary diagnosis and treatment operations have relatively low requirements for water quality, while surgical operations such as tooth extraction have high requirements for water quality. The existing built-in water channel system cannot flexibly switch between ordinary operations and operations with high water quality requirements, resulting in an increased risk of postoperative infection in patients in operations such as tooth extraction. Based on this, in order to meet the high water quality requirements of surgical tooth extraction and other operations, while avoiding the drug resistance problems caused by long-term disinfection of built-in water channels, it is particularly necessary to design an external dental handpiece water supply system. The system is designed for high-speed mobile phones. Through the "one person one change" method, the pollution problem of the built-in water channel is completely isolated to ensure the high quality of water for diagnosis and treatment. For common diagnosis and treatment operations, the built-in water system of the comprehensive oral treatment table can still be used, while for operations with high water quality requirements such as surgical tooth extraction, high-quality diagnosis and treatment water can be provided through an external water supply system, thereby effectively reducing the risk of postoperative infection for patients and improving the safety of diagnosis and treatment. This design can not only meet the needs of different diagnosis and treatment scenarios, but also significantly improve the safety of diagnosis and treatment water, and help implement hospital infection control.
