Description
Technical Field
The invention relates to the field of disinfection equipment, in particular to a negative pressure ward entrance guard disinfection machine.
Background
The negative pressure ward refers to a ward in which the air pressure inside the ward is lower than the air pressure outside the ward. This is also an important condition that has been particularly emphasized by the WHO when prescribing a rescue to a sars patient, and is now available in many hospitals in the country.
The negative pressure ward is that under a special device, the air pressure in the ward is lower than the air pressure outside the ward, so that only fresh air outside can flow into the ward from the air circulation, and air polluted by a patient in the ward cannot leak out but is timely discharged to a fixed place through a special channel. Therefore, places outside the ward are not polluted, so that the chance of massive infection of medical staff is reduced, and the ward is most suitable for rescuing patients with respiratory infectious diseases like SARS.
However, the sterilization of the negative pressure ward is strict, so that an access control sterilizer which can be conveniently sterilized is urgently needed.
