Abstract

The invention discloses a negative-pressure isolating helmet and relates to the field of infectious disease treatment and transportation. The negative-pressure isolating helmet comprises a helmet body, a half-length gown, an air exhaust hose and an air exhaust filtration system, wherein the helmet body is arranged on the half-length gown; the helmet body and the half-length gown are in air-tightness connection with each other; the helmet body is connected with the air exhaust filtration system through the air exhaust hose; and a one-way air inlet valve is arranged at the top of the helmet body. The negative-pressure isolating helmet disclosed by the invention is used for an infectious patient and the interference in the free movement of the infectious patient is avoided; the normal unrestricted movements of the head and the neck of a wearer are guaranteed; and the negative-pressure isolating helmet is convenient to carry because the size of the air exhaust filtration system is small.

Description

technical field [0001] The invention relates to the field of infectious disease treatment and transfer, in particular to a negative pressure isolation hood. Background technique [0002] The outbreak of severe infectious diseases such as SARS and Ebola has brought great risks to front-line rescuers. At present, people have developed positive pressure biological protective clothing and positive pressure biological protective hoods to protect rescuers, medical staff and researchers who are exposed to severe infectious diseases. However, how to prevent personnel infected with severe infectious diseases from releasing strong pathogens into the environment is one of the problems to be solved urgently. The negative pressure isolation hood can maintain a stable negative pressure environment inside the hood. When worn by patients with infectious diseases, it can effectively prevent the aerosols produced by them from spreading to the surrounding environment, which is very important ...
