Modified nano titanium dioxide photocatalyst oral cavity consulting room spray and aerosol suction device

Abstract

The invention discloses a modified nano titanium dioxide photocatalyst oral cavity consulting room spray and aerosol suction device which comprises an air suction mask, a box body, a spray and aerosolfiltering and pathogen killing device, a negative pressure suction system and a liquid discharging system. A separation mechanism is arranged in the box body, a spray and aerosol filtering and pathogen killing device is installed in an upper cavity, and a negative pressure suction system and a liquid discharging system are installed in a lower cavity. The air suction mask is connected with an airinlet located in the upper cavity of the box body through a connecting pipe. Spray and aerosol are strongly sucked into the upper cavity in the box body through the air suction mask and enter the spray and aerosol filtering and pathogen killing device through the negative pressure suction system to be used for killing bacteria or virus microorganisms contained in the spray and the aerosol. And liquid pollutants generated by condensation of the spray and the aerosol in the filtering process are collected through the liquid discharging system. The defects that a traditional oral cavity suctionmachine is single in function, simple in structure and incapable of achieving sterilization and disinfection are overcome.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a modified nano-titanium dioxide photocatalyst oral clinic droplet and aerosol suction device. Background technique [0002] During the clinical operation in the dental clinic, there are many patients for diagnosis and treatment, and power equipment such as ultrasonic equipment, high-speed mobile phones, turbines, and three-purpose guns are frequently used. Since the vast majority of oral clinical operations are carried out in the patient's mouth, oral power instruments directly contact the patient's saliva and blood, so these power instruments will generate a large number of droplets and aerosols that may contain microorganisms such as bacteria or viruses when they are rotated at high speeds. in the air. Some studies have found that the pollution range of aerosol in a closed dental clinic can almost spread to the entire clinic. Aerosol is a dispersion system in which solid or l...

AI Technical Summary

Problems solved by technology

[0007] The present invention overcomes the disadvantages of the above-mentioned traditional extraoral suction machine, and provides a modified nano-titanium dioxide photocatalyst suction device for dental office droplets and aerosols with sterilizing and disinfecting functions. The droplets and aerosols containing pathogenic microorganisms can be collected powerfully and immediately to effectively prevent the spread of droplets and aerosols, and the inhaled droplets and aerosols can be sterilized and disinfected through the modified nano-titanium dioxide photocatalyst microbial filtration device , greatly improving the sterilization efficiency and sterilization effect of the oral air suction device, effectively controlling the pathogen content in the air of the dental clinic, effectively blocking the transmission of infectious diseases through droplets and aerosols, and reducing the transmission through droplets and aerosols Air pollution caused by pathogenic microorganisms, ensuring the cleanliness of the dental clinic, maintaining the health of medical staff and patients, avoiding the shortcomings of the traditional oral suction machine, which has a single function and simple structure and cannot be sterilized, thus ensuring oral diagnosis and treatment activities during the epidemic normal progress
