Individualized miniature breathing circulation isolation sterilizing machine of wearing

Technical Field

The invention relates to the technical field of medical equipment, in particular to an individually worn miniature breathing circulation isolation disinfection machine.

Background

When infectious diseases occur, the ancient and direct method for isolating the infectious diseases can help people to fight against the infectious diseases, particularly the virulent infectious diseases, and the infectious diseases can be controlled in a short period as long as the isolation of the infectious sources is made. The traditional view of the prevention and control of infectious diseases at present focuses on the individual protection of uninfected people by using protective masks, goggles, chemical protective clothing and isolation gowns to avoid infection, but the individual isolation and disinfection protection equipment and products of determined or potential infection sources such as diagnosed infected patients, suspected/mild/asymptomatic drug carriers and even close-contact patients are lacked, only suspected patients are isolated by methods such as wearing masks, single covering and individual household isolation, and the existing protection products are more or less focused on disinfection and sterilization components and functions, so that a small number of original infection sources are in a relatively open and moving state, viruses and infection sources cannot be killed in a limited and small space of an individual, and the viruses and infection sources are scattered to a larger space around to cause larger spread, and even cause secondary contact infection, The aggregate is dispersed, which results in greater personnel and social medical economic loss. The negative pressure isolation chamber and the negative pressure isolation ward can only realize the transfer and treatment functions of a small number of groups, cannot meet infectious diseases, have complex production flow, low yield, high cost and high price, and the negative pressure breathing disinfection machine for rescue has the disinfection function, but does not have portability, cannot realize individual wearing, and cannot meet the isolation observation process of a large number of infected patients, suspected patients and close contacts when a large epidemic situation occurs, and the individuation requirement and the effective cutting off of the transmission path of viruses and infectious sources in the process.

Therefore, the development of a head-mounted, miniature and individual device with a sterilizing function is urgently needed, wherein the individual device with the sterilizing function is emphasized, and the device can kill viruses from the source of the infection path and the early stage of epidemic situation transmission, effectively cut off the transmission path to the maximum extent, limit the virus scattering, avoid causing greater pollution, and reduce the pathogenic rate, the death rate and the infection rate of medical staff. In addition, the product also needs to meet the requirements of safety, portability and comfort, relatively low cost, easy mass production, folding, convenient storage, easy transportation and carrying and the like, and is beneficial to market transformation production, popularization and application. The invention provides a miniature breathing circulation isolation disinfection machine which is worn individually.
