Packaging of surgical instruments
1.Device packaging: usually refers to the packaging materials and packaging materials of medical devices to be sterilized. Packaging material means any material used for primary and sealed packaging that removes air, allows sterilizers to reach the instrument, and provides a microbial barrier. The package includes a pre-molded sterile barrier system and a sterile barrier system. The purpose of packaging is to establish a sterile barrier to ensure that the medical devices remain sterile during the storage period from sterilization to use, and remain sterile during transportation, use and other conditions within the effective period.
2. Pre-formed sterile barrier system: paper-plastic bags, hard containers, etc.
3. Packaging technology: Packaging technology includes assembly, check, packaging, sealing, marking and other steps. Select appropriate, clean and complete packaging materials, and wrap the equipment completely. The packaging volume should not be too large, and the package should not be too tight, so as to facilitate air discharge and sterilization agent penetration. Suitable protective devices should be used for sharp instruments.
4. Closure: fold repeatedly to form a relatively independent space for closing the package.
5, sealing: packaging layer with adhesive or hot melt method to connect the surface together.
6. Closure integrity: Closure conditions can ensure that the closure has at least the same degree of blocking microbial entry as other parts of the package.
7. Packaging integrity: the packaging is not physically damaged.
8, sterile barrier system: the use of packaging materials after closed operation of the package formed or the use of preformed packaging materials after sealing operation of the package formed. The aseptic barrier system has the function of resisting microorganisms, dust particles and water, providing a long safe period of aseptic storage, protecting the device from damage during handling, and maintaining aseptic transport, so that it can be used aseptically at the place of use.
