Description
Technical Field
The utility model relates to the technical field of protective equipment, in particular to a positive pressure protective air supply host.
Background
The positive pressure protection system utilizes a positive pressure air supply host to convey the filtered clean air to the hood/protective clothing for a user to use through an air supply pipeline. The current positive pressure air supply main machine mainly comprises a filter box, an air supply control main machine and a battery. To avoid contamination or infection of the user, it is generally necessary to kill the air entering the positive pressure air supply main unit.
At present, the positive pressure air supply host in the market is mainly divided into three types, wherein one type is air filtration through a filter membrane or a HEPA, and no other sterilizing device exists; the second is to connect the ozone device and the ozone detecting component to kill the air flow, but the killing mode is very unsafe, the ozone is a toxic gas, and although the detecting component controls the amount of the ozone, if the component malfunctions, the ozone device will cause damage to human body, and the design is contrary to the concept of safety of medical products; and thirdly, the ultraviolet device and the filter component are assembled together to kill the air entering the host.
However, the above-mentioned sterilizing methods are all used for sterilizing the air entering the positive pressure air supply main unit during the use process, so as to avoid the unclean air entering from the outside, and do not consider other pollution situations possibly existing in the positive pressure air supply main unit when not in use. If the positive pressure air supply main machine is not used, in order to avoid pollution and infection of air during subsequent continuous use, a head cover/protective clothing, an air supply pipeline and a filter box in the positive pressure protection system are all disposable, and the main machine mainly realizes sterilization and disinfection of the outside of the main machine by soaking or wiping, and no matter the main machine is soaked or wiped, the polluted disposable parts are required to be removed firstly. During disassembly of the product from the contaminated disposable part, some microorganisms may enter the host internal piping through various routes. No matter the disinfection mode of soaking or wiping is adopted, the internal pipeline can not be effectively disinfected. The residual microorganisms in the internal pipeline may blow the residual microorganisms into the hood/protective clothing when the internal pipeline is used next time, which causes safety hazards to the use.
