The Reuse Rate Of Medical Packaging Bag

The reuse rate of medical packaging bag:

1. The selected sterilizer must be allowed to effectively penetrate and matched with other processes of the selected sterilization method, such as drying;

2. Ensure the asepsis of the contents before the aseptic package is opened;

3. It is easy for users to open the aseptic bag for aseptic operation, and can not pollute the contents;

4. The contents of the sterile bag must be kept aseptic at the time of use.

Medical packaging materials can be divided into reusable packaging materials and disposable packaging materials.

Reused packaging materials include cotton, hard containers:

Cotton cloth is a packaging material used in hospitals for a long time. It has good softness, compliance, repeatability, high tensile strength and easy to use. However, its microbial barrier function is poor, the rate of bacterial resistance is low, and its sterile validity period is only 14 days. Cotton wadding is an important cause of iatrogenic infection. And the use of the need to record The Times of use, in the actual use process is difficult to do.

Hard containers are usually made of aluminum alloy, stainless steel, etc., with a removable and sealable lid. It provides an excellent microbial barrier, an anti-fire resistance fluid, and protects equipment from the risk of damage during storage and transportation. Hard container is heavy, improper handling will cause ergonomic damage; The initial purchase cost is high and the cleaning process is demanding.

Disposable packaging materials include non-woven cloth, wrinkle paper, paper plastic bag/polyolefin plastic bag:

Nonwoven fabrics are made of oriented or random fibers by a high-temperature pressing technique. The pore size is very small, forming a good microbial barrier, high rate of bacterial resistance and validity up to 6 months; Allow the discharge of air and the penetration of sterilization factors such as water vapor; No flocculation, good hydrophobicity, good drape, high strength.

Medical wrinkle paper has better microbial barrier performance than cotton, and can be directly used as packaging material or used as the inner packaging material of hard containers. Low fiber floc, low cost. However, its package compliance performance and anti-puncture performance are poor, so the package should not be too tight or too loose. General moisture resistance and flammable.

Packing materials such as paper plastic bag/polyolefin plastic bag are suitable for sterilization of small and light weight items, with good microbial barrier function, and the items in the sterilization bag can be directly seen through the transparent plastic surface. Paper plastic bag can not be used for dry heat sterilization and plasma sterilization, polyolefin plastic bag is suitable for plasma sterilization, but can not withstand high temperature and high pressure.
