Description

Medical hyperbaric oxygen chamber sterilization and disinfection device TECHNICAL FIELD

[0001] The present application relates to the medical hyperbaric oxygen chamber disinfection technical field, specifically to a medical hyperbaric oxygen chamber sterilization and disinfection device. BACKGROUND

[0002] The medical hyperbaric oxygen chamber is a special medical equipment, which is mainly used for the treatment of anaerobic bacterial infection, carbon monoxide poisoning, ischemic and anoxic encephalopathy and other diseases in clinic. It is found in clinic that the medical hyperbaric oxygen chamber has absolute advantages for the blood oxygen saturation of infectious virus infected personnel, and can effectively reduce the mortality of infected personnel. TECHNICAL PROBLEM

[0003] However, there is no special pathogenic oxygen for infectious virus infected personnel at present. If the ordinary medical hyperbaric oxygen chamber is used to treat patients infected with infectious virus, due to the limitations of the traditional structure and use method of the ordinary medical hyperbaric oxygen chamber, it is easy to form a large virus pollution source. The traditional disinfection method can only disinfect the internal space of the medical hyperbaric oxygen chamber, and cannot disinfect the pipeline system. At present, the treatment waste gas discharged from the medical hyperbaric oxygen chamber also cannot be effectively disinfected and sterilized, so the treatment waste gas discharged from the medical hyperbaric oxygen chamber also forms a new pollution source. Therefore, the use of ordinary medical hyperbaric oxygen chamber to treat patients infected with infectious virus has a great risk of infection. Therefore, we propose a medical hyperbaric oxygen chamber sterilization and disinfection device. TECHNICAL SCHEME
