PORTABLE ISOLATION CHAMBER PROTECTING NURSING STAFF FROM INFECTIONS

摘要

ortable isolation chamber 1 with moving doors permitting the fluctuation of the air flow speed from outside to the inside of the chamber 5 for protecting nursing staff from infections, which chamber covers the bed of the patient 4, bears an accessory for the connection of medical provisions 5, and impedes the escape of air-transported particles towards the exterior of the chamber with forced horizontal, or vertical, or combinational horizontal and vertical flow of air from the inside of the isolation chamber to the outside thereof. The isolation chamber in question is furnished with microbe-retaining filters placed all over its inner surfaces 2, or a virus-exterminating system composed of microbe-retaining filters 6 positioned at the inner side of the chamber and the entry of the system, air conducts 7, a motor 8, and a virus exterminating unit 9 operating with chlorine, strong surface agents or high temperature. The principles of the operation and the advantages of said portable chamber are based on: a) the permanent elimination of air- transported particles, with air current passing over and around the bed of the patient and sent away from nursing staff; b) the retention of microbes by special filters and c) the neutralization of viruses, that are not retained by filters, with air current passing, before being expanded in the atmosphere, through the extermination unit.
