The human body is the largest source of mobile pollution in a clean area. Aseptic dressing is the first and critical step before entering the aseptic operation area. Improper operation will bring microorganisms, dust particles, fibers and other substances into the aseptic area, causing cross-contamination. The complete standard aseptic dressing operation process training generally takes several hours or tens of hours, and can only pass after careful assessment and verification, which shows its importance. Employees must keep in mind the following basic judgment principles when performing aseptic changing operations.
1. Any item without a reliable sterilization process is regarded as "bacteria". Personnel cannot be sterilized, so it is regarded as "bacteria".
2. After a reliable sterilization process, it becomes "sterile". But this aseptic state is time-limited. Those that have passed the time limit are regarded as "bacteria".
3. Aseptic products are regarded as "bacteria" upon contact with "bacteria". Need to be re-sterilized.
4. When "sterile" encounters "bacteria", it is also regarded as "bacteria".
5. A scientifically designed "aseptic dressing process" is the guarantee for the implementation of the concept of aseptic dressing.
Second, explanation
1. Hands and gloves: Bare hands are always bacteria-infected, even spraying disinfectant will not work. When wearing sterile gloves, bare hands should not touch the outer surface of the glove, only the inner surface. The inner surface of the glove becomes "bacterial" when it touches the bare hand, and the outer surface of the glove is in a "sterile state". Gloves are broken during work or come into contact with any "non-sterile" objects, which means "bacteria".
2. Head and face: For the human body, the head is the easiest to pollute the external clean area, especially the eyes and respiratory organs are easy to fall off or excrete pollutants. In addition to strengthening the protection of the head, it is also necessary to avoid touching the head with hands wearing sterile gloves as much as possible, thereby destroying the "sterile" state of the gloves. When the aseptic dressing operation is completed, all protections of the whole body must be neatly in place and no exposed.
3. Wear aseptic one-piece clean clothes: This is the most critical moment for aseptic changing. This locker room is a special zone, part of which is a "bacterial zone" and part of a sterile zone. First of all, when a person stands in the "bacteria zone", take a set of one-piece clean clothes. Pay attention that the hands can only touch the inner surface of the clean clothes. Aseptic surface meets the aseptic surface is the most basic principle of the whole dressing process. Reach in one foot first, and step on the "sterile field" after putting it on. When dressing, the outer surface of the other trouser leg and sleeve must not touch any other surfaces, including walls, floors, and the human body, otherwise the "sterile" state will be lost. The coveralls must be replaced again. Put the worn foot on the "sterile area" and put on the other foot. After putting on, step on the "sterile area" and put on the sleeves. When dressing, the outer surface of the sleeve must not touch any other surfaces, including walls, floors and the human body, otherwise it will lose its "sterile" state. The coveralls must be replaced again. If there is no mistake in dressing, after entering the "sterile area", it is not allowed to return to the "bacterial area".
4. Put on the sterile clothes and enter the work room. The door of the room should not be equipped with a handle so that the personnel can push it open with the elbow. It is best to open and close the door automatically to ensure that the sterile gloves are "sterile." The handle touched by many people is a potential source of contamination.
5. When working or not working, put your hands on your chest. Don't support it on other facilities, and don't sag. The human body cannot lean on any objects to avoid contamination of clean clothes.
6. When operating in a clean area or aseptic area, clean personnel should not move or operate significantly, otherwise it will cause serious pollution.
