The spray disinfection air shower room has dual functions: spray sterilization and air shower dust removal. It can meet the strict requirements of the biomedicine field for a sterile and clean environment. The specific application scenarios are as follows.
Disinfection for personnel access in biopharmaceutical production workshops
In the production workshops of vaccines, antibody drugs, biological preparations, etc., personnel need to pass through the spray disinfection air shower room before entering the clean area (such as 10,000-level and 100-level clean workshops). The equipment first sprays disinfectants such as hydrogen peroxide and hypochlorous acid that meet biomedical standards through atomizing nozzles to disinfect the entire body of personnel (including protective clothing, shoe covers, and the gaps between gloves) in a 360°, all-round manner, killing bacteria, viruses and other microorganisms that may be carried on the body surface. Subsequently, the high-speed air shower is activated to remove the disinfectant droplets and fine dust remaining on the body surface after disinfection, preventing the disinfectant residue from contaminating the production raw materials. At the same time, it avoids the entry of external particles into the clean workshop, ensuring that the drug production meets the requirements of GMP (Good Manufacturing Practice for Drugs).
Disinfection of sample and instrument transfer in biological laboratories
In microbiology and cell culture laboratories, external incoming experimental samples and sterilized equipment need to be disinfected through the transfer window of the spray disinfection air shower room. These might include clinical tissue samples, environmental microbial samples, petri dishes, and pipettes. The equipment sprays low-corrosive disinfectants on the outer packaging of samples and the surface of utensils to kill any possible adhering foreign bacteria. This prevents cross-contamination of samples or the invasion of the laboratory by external microorganisms. The air shower section can remove the dust on the surface of the packaging. This prevents dust from affecting the accuracy of experimental results. It is especially suitable for scenarios that are sensitive to environmental cleanliness, such as genetic engineering and microbial fermentation.
Disinfection of personnel and materials in the biomedical animal room
In SPF (Specific Pathogen-free) grade animal rooms and animal experiment facilities, personnel must complete full-body disinfection through a spray disinfection air shower room before entering the animal breeding area. This kills possible pathogens such as parasites and viruses they may carry and prevents infection of experimental animals. Materials entering the animal room, such as feed, bedding, and experimental equipment, also need to be disinfected through this device. This step prevents the introduction of external pathogens and ensures the health of the animals and the reliability of the experimental data. In addition, before waste generated in the animal room, such as contaminated bedding and carcasses of experimental animals, is transferred out, preliminary disinfection using spray disinfection air showers may take place. This reduces the risk of pathogen spread.
Auxiliary disinfection around the biosafety cabinet
Around the operation area of biological safety cabinets (such as Class II and Class III biological safety cabinets), when personnel frequently enter and exit or when it is necessary to replenish experimental consumables, the spray disinfection air shower room can be used as an auxiliary disinfection facility. Before approaching the biosafety cabinet, personnel can quickly complete local spray disinfection and air shower through the equipment, reducing the interference of microorganisms on the personnel’s body surface to the aseptic environment inside the safety cabinet. This is especially suitable for experimental scenarios dealing with highly pathogenic microorganisms (such as the novel coronavirus and tuberculosis bacillus), further enhancing the level of biosafety protection.
