Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, the utility model relates to a soft endoscope bedside pretreatment liquid preparation device. Background Art

[0002] With the rapid development of minimally invasive technology, soft endoscopes have become very important clinical diagnostic and treatment tools; since soft endoscopes are expensive and precision instruments, with characteristics such as complex design, special materials, and narrow lumens, if the endoscope is not thoroughly cleaned and disinfected, it is very easy to cause iatrogenic cross-infection; however, in recent years, the reports of endoscope-related infection incidents have continued to increase, causing serious harm to patients; therefore, a cleaning and disinfection device that can perform higher standards is needed to ensure the quality of endoscope reprocessing.

[0003] Among them, the technical specification for cleaning and disinfecting soft endoscopes requires reprocessing in the process of pretreatment → leak detection → manual cleaning → rinsing → disinfection / sterilization → drying → storage.

[0004] Among them, clinically, before the doctor starts seeing patients, the multi-enzyme cleaning agent and water are proportionally prepared in a plastic bucket, and the dry gauze is moistened with the cleaning solution for the endoscopic examination of the day; the following problems exist: 1. It cannot ensure the clinical indicators of preparing the multi-enzyme cleaning solution immediately before use and replacing it for each endoscope, and there is a risk of cross-infection; 2. Since the multi-enzyme cleaning agent has a relatively high price and can only exert the best activity at a certain water temperature, and the existing mode cannot ensure the preparation of the multi-enzyme cleaning solution at the best temperature and in an appropriate amount, which is likely to lead to waste of resources and artificially increase the cleaning and disinfection cost.

[0005] Among them, the "disposable endoscopic bedside pretreatment box" with the Chinese patent publication number CN210115288U solves the problem of "one-time use and one-time replacement", but the used pretreatment box is still a pre-prepared cleaning solution, and the problem of "preparing the multi-enzyme cleaning solution immediately before use at the best temperature and in an appropriate amount" has not been solved yet.

[0006] Among them, the "electric liquid preparation device" with the Chinese patent publication number CN210449000U only solves the problem of "multi-enzyme cleaning solution ratio" in the bedside pretreatment stage; however, it not only does not solve the problem of "one-time use and one-time replacement", but also lacks measures to maintain the best temperature for the prepared multi-enzyme cleaning solution.

[0007] Therefore, it is difficult to solve the problem of "preparing immediately before use at the bedside and one-time use and one-time replacement" only from the combination of the above-mentioned disclosed documents and the prior art. Therefore, the utility model proposes a soft endoscope bedside pretreatment liquid preparation device as a further improvement. Content of the Utility Model
