Technical Field

[0001] This utility model relates to the field of oral medical devices, and in particular to a dental aerosol suction device. Background Technology

[0002] In routine dental treatments, such as fillings, extractions, and root canals, high-speed turbine drills are typically used to drill and polish teeth. This process generates a significant amount of aerosols, sprayed droplets, and contaminants such as blood because the high-pressure gas used for power and the cooling water mist required to cool the drill bit. These contaminants can splash outside the oral cavity, polluting the air for medical staff and the dental clinic, increasing the risk of infectious disease infection and transmission.

[0003] Currently, there are few devices on the market that can collect and treat contaminants such as aerosols, droplets, and bodily fluids generated during oral treatment. Most existing devices are simply placed next to the patient's mouth for suction, which has a small coverage area and limited suction effect, making it difficult to effectively prevent the splashing and spread of contaminants. Therefore, this utility model proposes a dental aerosol suction device to solve the above problems. Utility Model Content
