Sterilization packaging bag method is as follows:
A, self-sealing sterilization packaging bag:
? ? Uncover the medical self-adhesive tape, along the dotted line of the seal can be pasted.
II. Heat-sealed sterilized pouches, sterilizing operation using a sealing machine
When using a sealing machine for paper-plastic pouches, please pay attention to checking the accuracy of the date of sealing, and checking the validity of the date after sealing. When the handwriting becomes lighter, please add printer ink promptly. The temperature of the medical sealer is usually 180°C to melt the polypropylene into liquid form and extrude the film into paper fibers. The width of the sealing pattern of the paper-plastic package should be ≥ 6mm, and the seal must be a continuous and consecutive shape, flat and without wrinkles, no bubbles or leakage of liquid.
. When packaging, please check the cleanliness and dryness of the packaged items. During autoclaving, the equipment is not completely cleaned and the remaining oil and moisture soak the paper surface only to form a wet package.
3. Protect sharp instrument parts, such as sharp scissors, etc., by covering them with silicone or rubber tubing so that they do not puncture the paper-plastic package, resulting in sterilization failure;
4. Paper-plastic bags must be properly cut and accurately used to remove air, soak in disinfectant and dry. Expelling unwanted air will be a barrier to heat and moisture, so as much air as possible should be removed before sealing. Also, bags should not be too full. Stretching the paper-plastic bag may result in tearing of the paper or rupture of the seal during sterilization or movement; other equipment crowds the bag and there is not some room in the bag, which is not good for steam. Soak and circulate, steam collects easily on the plastic surface of the bag and is difficult to vaporize and easy to produce wet packaging. However, the bag should not be too large, as movement of the bag may cause the contents to slide from one end to the other or from one side to the other. Excessive sliding may damage the seal or puncture the paper side. A relatively large amount of air also remains in the bag, which produces more condensation in the bag when heated, and the excess condensation does not fully evaporate, which tends to result in a wet bag. Therefore, to allow room for bag shortening and circulation, a space of approximately 2.5cm should be left between the unit and the sealed edge of the bag. For larger bags, after sealing one end, gently press on the air in the bag to expel it, then seal the other end. With less cold air in the bag, there will be less condensation in the bag when it is heated, which causes moisture reducing the likelihood of packaging.
