Local pollution-free positive pressure isolation system

Abstract

The invention discloses a local pollution-free positive pressure isolation system which comprises a positive pressure ward, a positive pressure adjusting device is arranged on the positive pressure ward, and the positive pressure adjusting device comprises an intelligent disinfection device, an exhaust fan, a drug-resistant bacterium sterilization device, an isolation container, an automatic exhaust valve, an air interchanger and a control device. The intelligent disinfection device is fixed to the positive pressure ward and used for conducting automatic spraying disinfection on the positive pressure ward, the exhaust fan is connected with the interior of the positive pressure ward and the interior of the drug-resistant bacterium sterilization device through a gas collection pipeline, and according to the local pollution-free positive pressure isolation system, the sterile state before the isolation container is used can be achieved, the system cannot be polluted by environmental microorganisms during isolation, so that anti-pollution isolation is achieved, the positive pressure state in the ward can be maintained all the time, meanwhile, the arranged intelligent disinfection device can automatically and regularly disinfect the interior of the positive pressure ward, an intelligent process is adopted in the whole process, the working efficiency is improved, and manpower input is not needed.

Description

technical field [0001] The invention relates to the technical field of isolation wards, in particular to a local pollution-free positive pressure isolation system. Background technique [0002] The isolation ward is to take physical measures to isolate it from other patients, so as to prevent the spread of pathogenic microorganisms through the air, or to protect patients from the threat of polluted air. Most of the positive pressure isolation wards use adjustable pressure medical pipeline compressed air to cause positive pressure in the partial isolation container, avoid backflow of external air, avoid contamination of external harmful microorganisms, and prevent infection of patients by harmful environmental microorganisms. [0003] The so-called positive pressure ward means that under special equipment, the air pressure in the ward is higher than the air pressure outside the ward. In this case, in terms of air circulation, the fresh air outside cannot flow into the ward, a...

AI Technical Summary

Problems solved by technology

[0004] The existing positive pressure isolation ward is expensive, and the secondary use cannot guarantee that it is pollution-free, and it cannot truly achieve pollution-free isolation. In this way, patients with infectious diseases in the ICU ward, after regular treatment, are critically ill and have low immunity. factors, it is often reinfected by drug-resistant bacteria in the ward environment, which greatly reduces the success rate of treatment, and the existing positive pressure ward needs to be disinfected regularly, and manual disinfection is inefficient, time-consuming and laborious
