Negative pressure isolation cabin laser disinfection device

Abstract

The invention discloses a negative pressure isolation cabin laser disinfection device, which adopts a high-energy ultraviolet laser to rapidly disinfect viruses and bacteria in air discharged from a negative pressure isolation cabin, an ultraviolet laser module drives an ultraviolet laser tube to emit high-intensity ultraviolet light by a driving plate, a concave lens converts divergent ultraviolet laser into straight high-intensity ultraviolet laser, and the ultraviolet laser is irradiated by the high-intensity ultraviolet laser. The exhaust pipe can be filled with straight ultraviolet laser, so that pathogenic bacteria such as new coronavirus, staphylococcus aureus, tritirachium album and escherichia coli can be efficiently inactivated. The whole device is simple in structure, the disinfection process is rapid and sufficient, and bacteria and viruses in the isolation cabin can be effectively prevented from polluting the environment outside the cabin.

Description

technical field [0001] The invention relates to the technical field of disinfection treatment of medical equipment, in particular to a laser disinfection device for a negative pressure isolation cabin. Background technique [0002] The negative pressure isolation cabin integrates the emergency stretcher and the isolation cabin for infectious patients, which can realize the pressure difference between the inside and outside. After the negative pressure system is activated, the clean gas outside the cabin is pressed into the cabin in one direction, and the air in the cabin is squeezed and discharged into a special channel. After being filtered out, it blocks the transmission route of the source of infection during the transfer of patients who transmit infectious virus through aerosol (air), and minimizes the hidden danger of infection for medical staff and surrounding people. It is especially suitable for dense crowds and infectious diseases. It is used in centralized hospital...

AI Technical Summary

Problems solved by technology

[0003] The purification methods of the existing negative pressure isolation cabin are mainly high-voltage electrostatic field capture, ultraviolet disinfection, and activated carbon filtration to disinfect and purify the air in the cabin and then discharge it. Sol achieves high-efficiency filtration, but for some smaller nano-scale bacteria and viruses, such as the new coronavirus with a diameter of about 100nm, the disinfecting rate is not high, and the disinfection effect is not ideal
