Description

Technical Field

[0001] The utility model relates to oral medical equipment, in particular to a comprehensive oral treatment equipment with a water supply and drainage pipe flushing structure. Background Art

[0002] As an essential device and instrument for oral diagnosis and treatment, the internal pipes of the comprehensive oral treatment table are very small and complex. The water used for oral diagnosis and treatment passes through the internal water circuit of the comprehensive oral treatment table, and enters the patient's mouth through the dental handpiece, three-way gun, dental scaler and water cup filler, and directly contacts the patient's oral mucosa and wounds. Therefore, once there are microorganisms such as bacteria and fungi in the water for diagnosis and treatment, it is very easy to cause infection in the elderly, the weak and the immune-compromised people. In addition, the splashes and aerosols generated during the operation may pollute the air and the surrounding environment, increasing the risk of hospital infection.

[0003] Microbial contamination of the water system of comprehensive oral treatment tables has brought tremendous pressure to the infection control of oral diagnosis and treatment activities, and the problem of water system contamination has attracted widespread attention. Many cases of Legionella pneumophila infection among dentists or patients have been reported abroad, and it has been confirmed that it is related to Legionella pneumophila contamination of water system of comprehensive oral treatment tables. In China, the sanitary condition of the water system of comprehensive oral treatment tables has gradually received attention, and relevant local standards have been issued in many places. The standards propose that the water pipes for oral diagnosis and treatment should be flushed for 3 minutes before opening the clinic every day, and regular monitoring should be carried out to ensure that the total number of water colonies meets the requirements.

[0004] The comprehensive oral treatment table includes water supply pipes and drainage pipes. The water supply pipes enter the patient's mouth through dental handpieces, three-way guns and mouthwashes, and directly contact the patient's oral mucosa and wounds. If the water used for diagnosis and treatment is contaminated, it is very easy to cause hospital infection. The drainage pipes include spittoons, strong suction devices and weak suction devices. The suction device uses negative pressure to timely suck out the patient's blood, saliva, microorganisms, tooth tissue debris, and coolant of the dental drill bit during the diagnosis and treatment process. If the saliva suction pipe is not thoroughly cleaned and disinfected, bacteria will remain. The negative pressure generated when the saliva suction pipe is started again can cause aerosols containing microorganisms to spread to the surrounding areas of the diagnosis and treatment unit, which can cause environmental pollution and surgical wound infection.

[0005] To solve the above problems, there are several commonly used methods:

[0006] 1. Chemical disinfection: Install slightly acidic hypochlorous acid water, hydrogen peroxide silver ions, etc. at the oral treatment water terminal to continuously disinfect the pipeline;

[0007] 2. Physical disinfection: Install iodine resin and brominated hydantoin resin physical filters at the water inlet of the oral comprehensive treatment table to disinfect the pipeline;

[0008] 3. Pipeline flushing: Use a foot switch to flush the dental handpiece pipeline, and press the corresponding button to flush the three-purpose gun and mouthwash pipeline. For example, patent document CN213821836U discloses a pipeline flushing bucket for a comprehensive oral treatment table, which includes a barrel body and a barrel cover, a three-gun pipeline clamping hole is opened in the center of the barrel cover, and a plurality of handpiece pipeline clamping holes are also opened on the barrel cover. The edge of the handpiece pipeline clamping hole is sleeved with a sealed rubber ring, and the barrel cover is provided with two self-locking nylon tie clamping holes. The self-locking nylon tie passes through a self-locking nylon tie clamping hole and the three-gun pipeline clamping hole to form a self-locking nylon tie ring with adjustable ring size.

[0009] There are many disadvantages in the current methods for treating the water pipeline problem in oral diagnosis and treatment:

[0010] 1. Chemical disinfection: high cost and high energy consumption. It is necessary to renovate the pipelines of the whole hospital and add large equipment. It is necessary to consider factors such as the renovation situation, equipment floor space, equipment maintenance, storage of disinfectants, and budget.

[0011] 2. Physical disinfection: Each comprehensive oral treatment table needs to be installed with a physical filter device, which requires regular maintenance and replacement, and requires a high budget expenditure.

[0012] 3. Pipeline flushing: The existing pipeline flushing bucket of the oral comprehensive treatment table only involves the dental handpiece and three-way gun in the water supply pipeline, and does not cover the mouthwash pipeline and drainage pipeline in the water supply pipeline; there is no automatic or semi-automatic device, and a dedicated person is required to step on the dental handpiece foot switch to complete the operation. It takes a long time to complete a certain number of treatment tables, which increases the workload of the staff; it is dumped and disinfected after each use and kept dry for standby use, which increases the workload of the staff; during the use of the conventional automatic flushing oral comprehensive treatment table, the staff is required to regularly add a certain concentration of disinfectant solution. The effectiveness of the disinfectant solution is related to its concentration and needs to be accurately prepared and added. At the same time, if the disinfectant is not rinsed properly, there may be a safety hazard of accidentally entering the patient's body. Utility Model Content
