Negative pressure isolation operating device for oral diagnosis and treatment

Abstract

The invention provides a negative pressure isolation operating device for oral diagnosis and treatment. The device comprises: a negative pressure air sterilization machine, a supporting connecting pipe and an isolation protective cover, wherein the isolation protective cover includes a transparent observation cover and a protective enclosing curtain, the supporting connecting pipe has a hollow structure, one end of the supporting connecting pipe is connected with the negative pressure air sterilization machine, the other end of the supporting connecting pipe is connected with the transparent observation cover, an upper end of the protective enclosing curtain is connected with the transparent observation cover, a lower end of the protective enclosing curtain is used for allowing a patient to enter, and the lower end is sealed after the patient enters the isolation protective cover, then an enclosed space is formed in the isolation protective cover, an operating part, an instrument inletand an air inlet are arranged on the protective enclosing curtain, and an arm of an operator enters the interior of the isolation protective cover through the operating part to carry out diagnosis and treatment operation. The invention can perform negative pressure isolation on a local diagnosis and treatment area during oral medical treatment, prevent spread of droplets, water mist and aerosol generated during the oral diagnosis and treatment, prevent the diagnosis and treatment environment and related personnel from being polluted, and prevent cross infection.

Description

technical field [0001] The invention relates to a negative pressure isolation operation device for oral cavity diagnosis and treatment, in particular to a negative pressure isolation operation device for oral cavity diagnosis and treatment used for dental diagnosis and treatment, and belongs to the technical field of medical equipment and disinfection products. Background technique [0002] During dental diagnosis and treatment operations, high-speed turbine dental drills, ultrasonic dental scalers and other equipment will produce a large number of droplets, water mist and aerosols, which are easy to spread in the consulting room and the entire treatment institution, resulting in cross-cutting. Infection, in the past, only doctors did protection, and the protection level was low, such as wearing masks and goggles, etc., but there was no protection for other patients and the diagnosis and treatment environment, and the spread of droplets, water mist and aerosols was easy caus...

AI Technical Summary

Problems solved by technology

[0003] The existing aerosol suction device only puts the suction device close to the mouth of the patient. The suction efficiency of droplets, water mist and aerosol is very low, and only part of it is attracted, and the diagnosis and treatment area is not isolated. The transmission of aerosol still exists. Contamination of doctors, clinical environment and other personnel in dental clinics still exists

At the same time, the previous aerosol suction device only filtered the suctioned air without disinfection.
