Negative pressure ward access control sterilizer

Abstract

The invention discloses a negative pressure ward access control disinfection machine which comprises a porch, sealing doors are arranged at the two ends of the porch, access control recognition systems are arranged on the sealing doors, an air extraction opening is formed in the porch, an air extraction pump is connected to the air extraction opening, the air extraction pump is arranged on the outer side of the porch, and a disinfection gas nozzle is arranged at the top in the porch. The disinfection gas nozzles are connected with a disinfection air pump, the disinfection air pump is installed on the outer side of the porch, a ventilation pipe is installed on the disinfection air pump and connected with a disinfectant pool, and a dustproof cover is arranged on the outer side of the porch. Compared with the prior art, the porch has the advantages that air in the porch can be ensured to be in a to-be-disinfected state, the negative pressure ward cannot be opened before disinfection is completed, a door leading to the outside cannot be opened, it is ensured that the whole negative pressure ward and the outside air are in a complete isolation state, viruses cannot be brought into the negative pressure ward, and the negative pressure ward is prevented from being polluted. The risk that the patient infects other viruses is increased.

Description

technical field [0001] The invention relates to the field of disinfection equipment, in particular to a negative pressure ward access control disinfection machine. Background technique [0002] A negative pressure ward refers to a ward where the air pressure inside the ward is lower than the air pressure outside the ward. This is also an important condition that WHO has emphasized when rescuing SARS patients. Many hospitals in China can now reach this level. [0003] The so-called negative pressure ward means that under the special device, the air pressure in the ward is lower than the air pressure outside the ward. In this case, in terms of air circulation, only the fresh air from the outside can flow into the ward, and the inside of the ward is closed. The polluted air of the patient will not leak out, but will be discharged to a fixed place in time through a special channel. In this way, the place outside the ward will not be polluted, thereby reducing the chance of med...
