Embodiment 1

[0037] The negative pressure suction device next to the oral cavity chair includes a safety cover and a negative pressure suction power source, the safety cover is connected to the negative pressure suction power source, the safety cover includes a cover body 2 and a top cover 1, and the cover The top of the body 2 is provided with an opening, and the top cover 1 is rotatably installed on the top of the cover body 2 to seal the opening. One side of the safety cover is provided with a transparent window 12 on the same side as the transparent window 12 The safety cover is provided with an opening, and the safety cover is also provided with a suction port 23. After the top cover 1 is closed, the safety cover is a relatively airtight device. The material used for the safety cover is corrosion-resistant and portable light material such as stainless steel, and the surface can be sterilized with a disinfectant wet tissue; It is convenient to disinfect the inner wall; the transparent ...

Embodiment 2

[0058] The difference between embodiment 2 and embodiment 1 is that, in embodiment 2, the straight tube part is a tube with a rectangular cross-section, and the inclined side wall part is a plurality of slantingly extending upwards on the top edge of the straight tube part to form a platform shape. There are two plates connected to each other, and a window is arranged on the plate of one side of the inclined side, and glass is installed in the window, that is, the transparent window 12.

Embodiment 3

[0060] The difference between embodiment 3 and embodiment 1 is that in embodiment 3, the number of openings is more than 2, so as to facilitate the collaboration of multiple people.

Abstract

The invention discloses a negative pressure suction device beside an oral chair. The negative pressure suction device comprises a safety cover and a negative pressure suction power source, the safetycover is connected with the negative pressure suction power source, the safety cover comprises a cover body and a top cover; an opening is formed in the top of the cover body, the top cover is rotatably arranged at the top of the cover body and is used for sealing the opening, a transparent window is formed in one side of the safety cover, so that the internal situation can be observed conveniently, the safety cover at the same side of the transparent window is provided with an opening, and the safety cover is further provided with a suction opening. According to the negative pressure suctiondevice, the safety cover and the suction device are used, the diffusion of the powder in the safety cover is limited, and meanwhile, the mobility of the internal powder is increased, the problem thatthe repair materials such as denture powder and the like easily pollute the indoor air during denture repair is solved.

Description

technical field [0001] The invention belongs to the field of dental auxiliary appliances, and in particular relates to a negative pressure suction device next to an oral cavity chair. Background technique [0002] Although more and more people choose dental implants in recent years, most elderly people cannot accept implant surgery due to personal economic or physical tolerance. Therefore, removable partial dentures are still the main method for the restoration and treatment of dentition defects in elderly patients. Way. At present, the number of clinical patients is relatively large, and the proportion of the elderly group is also relatively large. There are many cases where removable denture repairs and denture relining, trimming and adjustment are required. However, the treatment process of the above situation has great disadvantages. For example, the self-setting plastic used in denture relining will produce a lot of irritating odor during the blending process. In addit...
