When using high-pressure steam sterilization, the wet package is prone to occur during the sterilization process, and the wet package appears after the pressure steam sterilizer is sterilized, which not only affects the sterilization quality, but also causes the secondary pollution of the wet sterilization package, so the wet package is prevented. Extremely important. ⶠ Poor steam quality: The quality of steam must be maintained during steam steam sterilization, ie saturated steam. The steam is not saturated, the water content is too much, and the wet package is easily generated during sterilization; the steam is supersaturated, the water content is too small, and the latent heat is released, which is not conducive to steam penetration. â·Drainage pipe Cause: The condensate in the pipeline before sterilization is not completely drained, and the condensed water is not smooth. If the trap and drain valve are faulty, the fibers and sediment in the filter are not removed in time, and the vent filter is blocked. , affecting the condensate and vacuum rate, the drainage pipe installation is unreasonable. ⸠sterilizer performance reasons: sterilizer has a long service life, the performance has changed, such as the sterilizer pressure gauge pointer can not recover to "0", sterilized cabinet door seal aging. The sterilizer is not preheated or the drying time of the article is short. â¹ Drying system Cause: The drying system has failed or the drying time is insufficient. Packing properly prepared before âº: preparing items to be sterilized prior to packaging inappropriate, excessive moisture, resulting in poor drying after sterilization. â» Loading problem: If the package is placed too densely, there is no gap between the packages, the sterilization package is too large and too heavy. 1 The moisture outside the package may be caused by the following conditions: the condensed water or the sterilized product dripping on the loading vehicle is in close contact with the inner wall of the cavity, and is wetted by the condensed water on the inner wall; the discharge steam line is distorted or blocked. 2 The moisture in the bag can be caused by the following conditions: too much sterilizing, producing more condensed water, not easy to vaporize; improper operation when loading or unloading the object, so that moisture can not be separated from the packaging; fabric packaging is too tight, paper packaging is unloaded Claim. å˜æ”¾ The storage method after sterilizing the item is incorrect: the storage environment fails to reach the corresponding temperature, humidity, ambient temperature, and humidity change too much, which can cause moisture condensation on the surface of the packaged fabric, causing pollution. The distance between the aseptic storage rack and the wall cannot reach 5~10cm, and the wall material should be affected by humidity and temperature, thus producing fungi and the like. â½ Sudden water stoppage and power failure: The steam in the sterilizer cannot be removed in time, causing the temperature in the sterilizer cavity to drop, and the steam is turned into water droplets to wet the sterilization package. Dryness detection method During the verification, select the largest (heaviest) sterilized material, and cool the sterilized articles for 30 minutes. Open the kit to check whether the contents of the bag are hydrated and whether the cloth is wet. Whether there are visible drops of water at the corners of the tray. If there is moisture or water droplets, the sterilization package needs to extend the drying time parameters. If there is condensed water after 20 minutes of drying, there are usually too many items inside, or the contents inside are too heavy and placed too densely. Measures to prevent wet packs 1 Guarantee steam quality: use saturated steam. 2 Prolong the drying time properly: The pressure sterilizer has set the drying time at the factory, but this drying time will change due to the actual application conditions, resulting in wet packaging due to insufficient drying time. 3 Strengthen the management of the users: Pre-job training is required for each user, and it is required to participate in the study carefully, master the operation rules of the sterilizer, memorize the precautions of autoclaving, and hold the certificate. 4 Establish a wet pack registration system: carefully register the situation of each wet pack, find the cause, and sometimes involve many links, so each step must be carefully checked to comprehensively summarize to avoid the occurrence of wet packets. 5 Strengthen the management of items before and after sterilization: Strengthening the training and standardization of operators to recognize the importance of it, while extending the cooling time, using the proper cooling method and the guarantee of the quality of the sterilized steam is also very important to reduce the generation of wet packets. In the future work, management should be strengthened to enable operators to strictly supervise the customs, establish a wet package registration system, analyze the relevant factors, and find out countermeasures and continuous improvement to control the occurrence of wet packets and ensure sterilization. quality. Functional oligosaccharides refer to oligosaccharides that are difficult or impossible to be digested and absorbed by the human body and have special physiological effects on the human body. Its sweetness is generally only 30-50% of that of sucrose, and it has physiological functions such as low-calorie, anti-caries, prevention and treatment of diabetes, and improvement of intestinal colony structure. Due to the special physiological functions of functional oligosaccharides, it becomes a nutrient and health care product. A new generation of food-effect raw materials that integrate diet and therapy. It is a new functional sugar source that replaces sucrose and has a wide range of uses and application prospects. Common functional oligosaccharides include: xylo-oligosaccharides, fructooligosaccharides, galacto-oligosaccharides, isomaltose, raffinose and so on.

What factors may cause wet bags?
1 Preparation of items before sterilization: Improve the packaging of the items: Choosing the right packaging is extremely important for sterilization and drying. 2 Management of articles after sterilization: With the correct cooling method, the sterilized articles in the cavity have a higher temperature. If they are directly exposed to a large amount of air outside, a large amount of temperature will be generated under the influence of a large temperature difference. Condensed water, resulting in a sterilized package of wet packs. Therefore, after the sterilization process is completed, the sterilizer can be removed by partially opening the sterilizer door and waiting for the temperature in the chamber to drop to about 80 °C. After removing the sterilized items, they should be cooled to room temperature before being placed in a sterile storage cabinet or sent to the appropriate room.
