Abstract

The invention relates to the technical field of medical instruments, in particular to a blowing and sucking type wind exhausting device for a dental chair. Round holes are formed in the two ends of sleeves on two sides so that a wind supplementing pipeline and a wind exhausting pipeline can penetrate through the round holes, and flexible pipelines are arranged outside the wind supplementing pipeline and the wind exhausting pipeline at the tail ends for fixing and protecting. A strip-seam-shaped wind exhausting hood and a strip-seam-shaped wind supplying hood are arranged at the tail ends of the flexible pipelines on the two sides respectively. The two ends of the wind supplementing pipeline are connected with the strip-seam-shaped wind supplying hood and the wind supplementing device respectively, a wind supplementing fan and a particulate matter filtering device are arranged in the wind supplementing device, an air inlet of the fan is connected with the particulate matter filtering device, and the particulate matter filtering device is connected outdoors through a hose. A wind exhausting fan, an air sterilization filter and a particulate matter filtering device are arranged in thewind exhausting device, an air exhaust port of the fan is connected with the air sterilization filter, and aerosol diffusion in the mouth of a patient during an oral surgery can be effectively isolated through a blowing and sucking type wind exhausting system formed by combining strip-seam-shaped wind exhausting hood and the strip-seam-shaped wind supplementing hood, so that the safety of dentists is protected, and indoor pollution diffusion is prevented.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a blow-suction air exhaust device for a dental chair. Background technique [0002] With the rapid development of social economy, the requirements of the contemporary public for high-quality indoor environment are gradually increasing. In recent years, indoor microbial aerosol pollution and related infectious diseases have attracted widespread attention from scholars at home and abroad, especially after the outbreak of the new crown pneumonia epidemic. Among them, the problem of microbial aerosol pollution in the dental clinic due to the oral treatment process has gradually attracted everyone's attention. [0003] Dental office bioaerosols can be produced in a variety of ways. The use of common surgical treatment instruments such as turbine handpieces and three-purpose air guns will produce a large amount of aerosols. Ultrasonic tooth cleaning, ultrasonic bone knife, ...
