Description
Technical Field
The invention relates to the technical field of bacterial biofilm incubation systems, in particular to a device for simulating a waterway of an oral comprehensive treatment table and a biofilm formation method.
Background
The waterway pollution problem of the oral cavity comprehensive treatment table is ubiquitous in the world, and the health safety of patients and medical staff is seriously threatened. Years of research prove that the waterway of the oral comprehensive treatment table is seriously polluted, the waterway is not treated, and microorganisms in a water sample per milliliter are high up to 108CFU contains conditional pathogenic bacteria such as Pseudomonas aeruginosa, Legionella pneumophila, etc. When the pathogenic microorganisms are used for oral treatment, the pathogenic microorganisms can enter wounds of patients along with the rotation of the mobile phone and water mist sprayed by the three-purpose gun, and hospital infection is caused. The medicine has great influence on people with low immunity, such as pregnant women, children, patients with malignant tumor chemotherapy, people taking immunosuppressive agent and people with immunity deficiency, such as patients with acquired immunodeficiency syndrome. Researches find that the problem of waterway pollution of the oral comprehensive treatment table is difficult to effectively solve and is mainly influenced by a biological film in a waterway pipeline. The biomembrane in the waterway is different from the growth mode of free bacteria, is a complex thallus combination, is a microorganism membranous polymer adhered to the surface of a certain living or non-living carrier, and the main components of the polymer comprise protein, carbohydrate, lipid, extracellular DNA and the like. Because the diameter of the waterway pipeline of the dental chair is small, the liquid flows slowly and stops intermittently, and the pollution is caused by instantaneous negative pressure suck-back of a high-speed mobile phone, a biological film is very easily generated in the pipeline. Once the biofilm is formed, the anchorage cells secrete polysaccharide-protein complex with high viscoelasticity, so that the polysaccharide-protein complex is formedDifficult to remove in the waterway of the dental chair, and has the capacities of resisting dryness and self-protection. In the dental treatment process, the biomembrane adhered to the surface of the pipeline can continuously release conditional pathogenic bacteria to the water path, and the conditional pathogenic bacteria enter a treatment part along with water flow to cause cross infection of dental treatment, so that a serious person can cause shock. Therefore, effective removal of biofilm, particularly biofilm formation in the prevention and control waterway pipes, is critical to controlling the occurrence of infection caused by the waterway of the dental chair. However, the research on the biomembrane is limited due to the high cost and the inconvenience of disassembling the dental chair. The method for simulating the waterway of the oral cavity comprehensive treatment table to form the biofilm mainly takes a static culture method as a main method at present, the waterway of the oral cavity comprehensive treatment table is in a dynamic and static state and is continuously changed, and is influenced by the suck-back of a high-speed mobile phone, and the existing static culture method cannot be close to a real growth environment, so that the judgment is influenced.
At present, the research on the dynamic simulation device and method for the waterway biofilm formation of the oral comprehensive treatment table is almost not available, and the only patent about the waterway pipeline biofilm formation mainly focuses on the aspect of tap water supply.
1. The invention discloses a long water pipeline pipe wall biofilm growth simulation experiment device and an experiment method (application number: 202010691936.9). The invention discloses the long water pipeline pipe wall biofilm growth simulation experiment device, although the method can simulate a multi-stage water pipeline network; the method can effectively simulate the growth process of the biomembrane on the wall of the long-distance water pipeline under the conditions of different lengths and different residence times, but because the conditions in the dental treatment process are complex, the method cannot consider the conditions of waterway circulation working time, high-speed handset suck-back and the like, cannot well approach the clinical use conditions, and is different from the research object of the research.
2. The invention discloses a biofilm growth simulation device of a hanging-piece type water supply pipeline in an outer cylinder (application number: 202110108547.3). The device has good stability, more hanging-piece positions and capability of simulating pipeline flow state, but is different from the research in aspects of biofilm formation methods, research objects and the like.
3. The invention discloses a reactor for in-situ culturing a pipeline biological membrane and a method thereof (application number: 202110231901.1). The reactor for in-situ culturing the pipeline biological membrane and the method thereof are disclosed, and the device has short membrane culturing period and high efficiency, but is different from the research on the aspects of a biological membrane forming method, a research object and the like.
Therefore, the invention provides a device for simulating the waterway biofilm formation of an oral comprehensive treatment table and a method for forming the biofilm, aiming at obtaining the biofilm through the construction of the device for simulating the waterway biofilm formation of the oral comprehensive treatment table and the exploration of the method for forming the biofilm, and facilitating the subsequent biofilm formation characteristic research and the removal effect research of different disinfectants on the biofilm.
