Technical Field
The embodiment of the invention relates to the field of medical auxiliary tools, in particular to a grinding device beside an oral chair with a function of preventing cross infection.
Background
The hospital environment infection prevention and control is an important link of 2019-nCov infection prevention and control, in the special oral treatment process, due to the use of splashing instruments such as a turbine and the like, secretion, saliva or blood of a patient and dust generated by a polished restoration body can splash to the surrounding environment, and if no protection device is provided, large-particle spray and dust can directly splash to pollute eye conjunctiva and oral and nasal mucosa of medical staff to cause infection; after the spray is stopped for a certain time, the droplet nuclei containing the microorganisms remain suspended in the air, and the atomized secretions, saliva, blood form aerosol particles of smaller diameter to form bioaerosols, which in certain cases can cause diseases by airborne transmission.
In the clinical work of the oral cavity, a large amount of dust is generated by polishing and repairing the oral cavity, so that aerosol suspended in air is formed, the method is an important way for causing cross infection in a consulting room, and especially during the outbreak of the epidemic situation of the novel coronavirus, the prevention and control of the air infection in the consulting room are very important during the operation of diagnosing and treating the oral cavity. In the prior art, only the prior art strictly screens the epidemic history of a patient before operation, selects a relatively closed diagnosis room, strengthens the protection measures of doctors, and reduces the risk of cross infection by performing operations such as timely disinfection treatment after splashing; or a simple dustproof grinding device in a mechanic's room is adopted for operation.
At present, no special device is arranged beside a chair for controlling dust generated during grinding and polishing of a restoration body, and dust diffusion is reduced only through an open negative pressure suction device. The polishing dustproof device in the laboratory of the technician has the defects of openness, incapability of performing chair-side operation and the like; the simple dustproof grinding device for the technicians designed by the scholars does not have a negative pressure suction function, absorbs dust through water on the bottom surface of the box body, is only suitable for the oral cavity mechanic grinding machine, and is inconvenient to operate.
