Description

Inhalation and exhalation bidirectional sterilizer
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to two-way sterilizer inhales, exhales.
Background
At present, only the space gathered on the human mouth or the space where the infectious disease patient stays is sprayed with disinfectant, but the disinfection time of the measure is very short, the disinfection space is limited, the effect cannot be lasting, and when respiratory infectious diseases such as influenza, new coronary pneumonia and the like are epidemic, a lot of infected patients still can be generated.
The respirator is commonly called a mask at home and abroad, and is named as a self-priming filtering type particle-preventing respirator according to the standard GB 2626 plus 2006 specification, and the main functions of the respirator are filtering particulate matters and large-diameter microorganisms. The international filtration efficiency for the mask samples was specified as: KN90 is more than or equal to 90 percent, and KN95 is more than or equal to 95 percent; the total leakage rate TIL is less than 13% and less than 11%, so that the mask mainly has a filtering effect on particulate matters and large-particle bacteria.
However, since the volume of the bacteria is generally between 0.2 and 100 micrometers, generally about 3 micrometers, and the diameter of the virus is about one percent of the bacteria, between 0.002 and 1 micrometer, generally less than 1 micrometer, when people use the mask daily, the exhaled air has aerosol larger than the aerosol inhaled in the air, and has oily suspended particles, which can reduce the electrical property of the electrostatic non-woven fabric, so that fine particle dust, bacteria and virus can penetrate through the mask, and the aerosol is saturated quickly as the mask is locally humidified during breathing, and the effect of filtering the virus is reduced or lost. The particle size of the aerosol is about 0.001-100 microns, and the aerosol is a parasitic source of viruses, and the viruses can penetrate or leak out of the mask along with the aerosol and spread in the air. Therefore, it is important to kill viruses in inhaled aerosols and viruses in exhaled aerosols, which are turbid, to prevent the spread of infectious diseases such as new coronary pneumonia.
At present, the breathing machine used in each hospital is mainly used for rescuing the life of critical patients, and mechanical artificial respiration is adopted to replace the autonomous ventilation function to supply oxygen to the patients. Various household assisted respirators are mainly used for preventing snores and apneas and cleaning filtered air.
The traditional respirator does not sterilize bacteria and viruses which are transmitted in the air, and cannot control the transmission of the bacteria and the viruses from the source, so that people inhale the bacteria and the viruses in the air when breathing, more seriously, the air exhaled by infected patients contains a large amount of bacteria and viruses, the bacteria and the viruses are dispersed in surrounding crowds, and other people also inhale the air with the bacteria and the viruses, so that the infectious diseases such as new coronary pneumonia are transmitted.
In addition, the traditional breathing machines need external power drive, so that more auxiliary devices are needed, the size is larger, the energy consumption is more, the breathing machines cannot be carried about, and the cost is higher.
