Description

Technical Field

[0001] This invention relates to the field of wet pack testing for disinfection, specifically a rotary sieving device for wet packs used in disinfection supply centers. Background Technology

[0002] The Central Sterile Supply Department (CSSD) is the unit responsible for supplying various sterile items within a hospital. It is responsible for the cleaning, packaging, sterilization, and supply of medical equipment. Modern hospitals supply a wide variety of items, involve numerous departments, and have rapid turnover; every aspect of the work is crucial to the quality of medical care, teaching, and research. Incomplete sterilization can lead to hospital-wide infections, and substandard supplies can affect diagnosis and treatment. Therefore, ensuring the proper functioning of the CSSD is extremely important. The CSSD most commonly uses autoclave sterilization, which is economical, efficient, and pollution-free; however, the phenomenon of wet packs often occurs after sterilization.

[0003] Definition of a wet pack: After the high-pressure pack has cooled (15 minutes), moisture is present on the surface or inside the pack. The wet pack itself is sterile, but water contact damages the packaging's protective properties, creating a pathway for microbial migration. Therefore, wet packs or suspected wet packs must be resterilized. According to the Ministry of Health's "Disinfection Technical Specifications": (1) For each dressing load that meets the equipment's maximum load requirements, the weight increase before and after sterilization should not exceed 1%, and there should be no visible damp spots; (2) For each metal load that meets the equipment's maximum load requirements, the weight increase before and after sterilization should not exceed 0.2%, and there should be no visible damp spots. Currently, the supply room usually uses visual inspection by staff to screen wet packs, which is inefficient and inaccurate. Chinese invention patent application number 202110320074.3 discloses a rapid detection device for wet packs in a disinfection supply center, including a detection mechanism, a transmission mechanism at its bottom, and a control component; the detection mechanism includes a detection frame, a base, and a detection device disposed within the detection frame; the transmission mechanism is wound around the base; the control component is embedded in the base; the detection device includes a weight detection component and a moisture detection component, which are electrically connected to a microprocessor within the control component.

[0004] The aforementioned detection device, by integrating a detection mechanism, a transmission mechanism, and control components into one unit, can not only quickly identify wet packs but also improve the efficiency and quality of work in the disinfection supply center. However, its shortcomings have been found during use: 1. Its structure is relatively complex, which is not conducive to reducing screening costs; 2. After the wet pack is detected, it needs to be manually removed, resulting in low automation; 3. The moisture detection component only detects the wet pack on one side, which has limitations and introduces errors, leading to inaccurate final detection results. Summary of the Invention
