Device used for blocking infecting of diseases such as novel coronavirus spread by droplets

Abstract

The invention provides a device used for blocking infecting of diseases such as novel coronavirus spread by droplets. The device comprises a chemical sterilization and disinfection unit, a physical sterilization and disinfection device, an air filter, a hood and other auxiliary unit. Different combinations of the units of the device can achieve two work states, the positive-pressure work state andthe negative-pressure work state. When the device is in the positive-pressure work state, the hood is full of sterilized and disinfected air, the pressure is higher than environment pressure, and thedevice is suitable for healthy personnel working in environments where people are likely to be infected. When the device is in the negative-pressure state, the internal pressure of the hood is lowerthan the environment pressure, air exhaled by users is exhausted into the environment after being sterilized and disinfected, and the device is suitable for being used by suspected infected patients or diagnosed infectious victims. According to the device capable of reducing the concentrations of bacterial viruses in the local environment through direct sterilization and disinfection, bacterial viruses are eliminated from the source and are killed before being diffused, healthy personnel who have to work in the environment are protected, and the patient recovery process is promoted.

Description

technical field [0001] The invention relates to an air sterilization and disinfection device for blocking or reducing cross-infection of infectious diseases, especially a device suitable for blocking or reducing the infection of diseases transmitted by patient droplets, such as the new coronavirus Covid-19. Background technique [0002] In viral influenza, SARS and the current novel coronavirus pneumonia disease outbreak, the generally accepted mechanism of epidemic transmission is mainly through the patient's cough, sneeze and oral droplets in speech to transmit the virus – exhalation in the following text has the same meaning . Inhalation into the respiratory system, contact between hands that have touched the surface of the virus and eye, nose, mouth and mouth membranes, and direct contact between healthy people and patients are the main channels for new patients to be infected. The large particles in the droplets sprayed by the patient generally can land quickly, while ...
