Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a multifunctional endoscope cleaning irrigation device. Background Art

[0002] Digestive endoscopes are a set of equipment that directly obtains images of the digestive tract through the mouth or anus, or obtains ordinary or magnified images of the digestive tract and ultrasonic images of the digestive organs through devices with ultrasonic narrow-band light, laser or confocal, and then diagnoses and treats digestive system diseases. Endoscopic examination has become an indispensable item in the diagnosis and treatment of digestive system diseases. Since the endoscope is in direct contact with the patient's skin, mucous membranes, secretions, and body fluids, it is very easy to bring pathogens into the body if it is contaminated and handled improperly, causing nosocomial infection. Therefore, cleaning, disinfection and sterilization are key links to ensure infection prevention and control.

[0003] At present, the cleaning and disinfection of digestive endoscopes are divided into manual cleaning and disinfection and fully automatic cleaning and disinfection machines. Regardless of the type of cleaning and disinfection, a full-pipeline irrigation device is required. There are two types of digestive endoscopes. The structures of the two digestive endoscopes are basically the same. The only difference is whether there is an attached water pipeline (clamp lifter pipeline). When cleaning and disinfecting endoscopes with attached water pipelines (clamp lifter pipelines), a special irrigation device for cleaning the attached water pipelines is required. When cleaning and disinfecting endoscopes without attached water pipelines, ordinary irrigation devices are used for cleaning and disinfection. Many places still use syringes to manually flush the endoscope's attached water pipelines (with clamp lifter pipelines) when cleaning endoscopes with attached water pipelines (clamp lifter pipelines). In the cleaning and disinfection process, each step requires manual syringe cleaning, which is too inefficient. Many times, there are irrigation devices with attached water, but the endoscope that needs to be cleaned is an endoscope without attached water. In this way, during the cleaning process, the water flow pressure is insufficient when the endoscope is cleaned and disinfected, and the disinfection fails to meet the standards. In another case, there is an irrigation device without attached water, but the endoscope that needs to be cleaned is equipped with an attached water pipeline. In this way, manually injecting the attached water pipeline with a syringe will increase working time and reduce work efficiency.

[0004] In summary, there is an urgent need to design a multifunctional endoscope cleaning perfusion device that overcomes the above-mentioned problems. Utility Model Content

[0015] Furthermore, the outer wall of the sealing cap is provided with anti-slip grooves.

[0016] Furthermore, the perfusion device also includes a connecting piece and a plug for sealing the water-gas interface of the digestive endoscope, and the connecting piece connects the first liquid outlet tube and the plug.
