Description

Air pressure adjustable type endoscope leakage detection control system

Technical Field

The utility model relates to an air pressure adjustable type endoscope leakage detection control system, and belongs to the technical field of soft type endoscope leakage detection devices.

Background

The soft endoscope is one of the most convenient, most direct and most effective medical instruments for medical staff to observe pathological tissues in human bodies, and has the advantages of high image definition, vivid colors and the like. As the application range is expanded, the soft endoscope gradually enters the treatment field from the diagnosis field, and the requirement of reprocessing the soft endoscope is also increasing. The basic principle of soft endoscope treatment is specified in WS507-2016 technical Specification for cleaning and disinfecting Soft endoscopes, wherein: the soft endoscope and accessories entering into the aseptic tissues and organs of human body or contacting with the damaged skin and mucous membrane should be sterilized.

With more and more treatment endoscopes, the storage environment of soft endoscopes is more and more important to clinic, and particularly secondary pollution is avoided in the storage process. Meanwhile, soft endoscopes with various functions and various models are more and more complete. The soft endoscopes have different appearance structures, and the mounting heights and the interval lengths of the stores of the soft endoscopes with different appearance structures are different, so that the universality of the existing fixed stores is poor.

The traditional manual leak detection link consumes more manpower in clinical work, and the endoscope is easily damaged if the operation link is improper, so that the control system with adjustable air pressure and feedback plays a vital role in the leak detection process. In the practical application process, the regulation and feedback of the air pressure can save material resources and manpower on one hand, reduce the capital expenditure of departments, and greatly reduce the damage to the endoscope caused by overhigh pressure in the leak detection link on the other hand. At present, a manual leak detection mode is adopted for the leak detection link of the soft endoscope, the pressure cannot be adjusted autonomously, a feedback mechanism is lacked, and a certain damage to the endoscope is easily caused; moreover, the current leak detection process lacks a control system for pressure regulation and protection, has poor universality and is not compatible with endoscopes of all brands. Taking a common soft endoscope as an example, the soft endoscope is connected with a manual leak detection device, a worker manually adds pressure to the endoscope, and then observes whether bubbles are generated after the pressure of the endoscope is reached. The whole leak detection process can be seen that the whole manual operation of a worker is needed, whether the set pressure value is reached or not is needed to be judged manually in the pressurization process, the leak detection result is needed to be judged manually in the pressure maintaining process after the pressure is reached, and the leak detection link lacks a pressure autonomous regulation and pressure protection system.
