Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical equipment, and more specifically, relates to a three-dimensional disinfection transfer window. Background Art

[0002] Pharmaceutical plants have very high requirements for the production environment. Usually, the production process of drugs is completed in a clean room, which has strict requirements on environmental parameters.

[0003] Therefore, GMP stipulates that items entering the sterile room must be strictly disinfected and sterilized, and all material transfer methods should be verified to prove that they can effectively remove microorganisms or dust particles on the surface of the inner packaging of the material. The sterilization transfer method of materials can use a continuous transfer tunnel oven, or a double-door wet heat or dry heat sterilizer, etc., according to the characteristics of the materials and process requirements. For items that cannot be sterilized by dry or wet heat, other suitable sterilization methods can be considered, such as irradiation, fumigation, ultraviolet irradiation, etc., and then passed into the sterile room through a double-door ultraviolet transfer window with strict SOP control. However, no matter what double-door sterile transfer method is used, a double-door interlock or double-door opening control and alarm system should be used to prevent the doors on both sides of the sterilizer from opening at the same time, and at the same time control and ensure that the door on the sterile area side can only be opened after the sterilization procedure is completed. In order to facilitate the transfer of materials across levels, double-layer packaging is recommended.

[0004] Generally speaking, according to the mode of action and nature of the disinfection method, we divide the disinfection methods into the following two categories:

[0005] ① Chemical method: the method of using chemical drugs to kill pathogenic microorganisms. Chemical drugs used for disinfection are called chemical disinfectants. If necessary, fumigation can be used to reduce microbial contamination in sanitary dead corners in the clean area, and the residual level of fumigants should be verified.

[0006] ② Physical methods: Use physical factors to kill or remove pathogens and other harmful microorganisms. Common methods include: Wet heat method (including cooking, pasteurization, flowing steam sterilization, pressure steam sterilization): heat conduction by air and water vapor; microwave: electromagnetic waves with a wavelength of 1 to 1000mm, and frequencies of 2450MHz and 915MHz; infrared: electromagnetic waves with a wavelength of 0.77 to 1000um; ultraviolet: wavelength range of 200 to 275nm, the best wavelength is 253.7nm; ionizing radiation: radiation sources include 60Co gamma rays, high-energy electron beam rays, and X-rays; filtration and adsorption: mainly used for the clean disinfection of liquid and gaseous substances; natural ventilation: using wind to dilute the concentration of microorganisms.

[0007] At present, in pharmaceutical workshops, the most widely used method for transferring items from non-clean areas to clean areas is ultraviolet transfer windows. Conventional ultraviolet transfer windows usually install ultraviolet lamps on the top of the transfer window cavity to sterilize items passing through the transfer window. This type of ultraviolet transfer window can only sterilize a part of the area of ​​the item, and the overall sterilization effect is poor. Utility Model Content
