Description

Technical Field

[0001] The invention relates to the field of endoscope pre-flushing, in particular to an automatic pre-flushing device. Background Art

[0002] Flexible endoscopes are invasive diagnostic and treatment tools that may cause a greater risk of cross-infection during the diagnosis and treatment of patients. Cleaning and disinfecting endoscopes after use is one of the important means to reduce the occurrence of cross-infection in hospitals. Flexible endoscopes removed from the patient's body are often contaminated with organic pollutants such as sugars, fats, and proteins. These surface pollutants may directly affect the effect of the disinfectant and may also form biofilms that hinder the penetration of the disinfectant. At the same time, protein-based mucopolysaccharides are very easy to dry up, which can easily cause cleaning difficulties. Therefore, it is particularly important to perform preliminary treatment before the endoscope is transported to reduce the residence time of pollutants. Effective pretreatment of flexible endoscopes can improve the cleaning and disinfection quality of flexible endoscopes and further ensure the safety of endoscopes.

[0003] According to WS 507-2016 "Technical Specifications for Cleaning and Disinfection of Flexible Endoscopes", bedside pretreatment of endoscopes should be carried out according to the following process: after the endoscope is removed from the patient's body, before it is separated from the light source and video processor, the dirt on the outer surface should be wiped off immediately with a wet wipe or wet gauze containing cleaning solution, and the wiping supplies should be disposable; repeatedly supply air and water for at least 10 seconds; place the tip of the endoscope in a container filled with cleaning solution, start the suction function, and suck the cleaning solution until it flows into the suction tube; cover the waterproof cover of the endoscope; put it in a transport container and send it to the cleaning and disinfection room. Among them, the cleaning solution used in the method of using the endoscope suction function to suck the cleaning solution until it flows into the suction tube to clean the internal channel of the endoscope is expensive, and in order to prevent infection, it is required that one endoscope be used per person. A small bucket of cleaning solution needs to be prepared for the pre-cleaning of each endoscope, and the cleaning solution is poured out after the endoscope is cleaned, resulting in waste.

[0004] The Chinese utility model patent with application number 202323481737.3 discloses a bedside endoscope pretreatment constant temperature device. Through a constant temperature pad and a cleaning box with multiple empty cavities, disposable cups can be placed in the empty cavities. A single endoscope corresponds to a cup to avoid cross infection; multiple cups need to be used. The Chinese utility model patent with application number 202320715852.3 discloses an endoscope pretreatment liquid preparation device. By arranging a heat preservation structure on the water outlet pipe, when the constant temperature water in the water storage bottle enters the container from the water outlet pipe, the heat preservation structure can be pulled downward, so that the heat preservation structure can connect the water outlet pipe with the container, thereby avoiding the constant temperature water flowing out of the water storage bottle from being directly exposed to the outside, so that the water temperature can easily meet the requirements of the enzyme washing solution; it mainly solves the constant temperature problem. The Chinese utility model patent with application number 202120555470.X discloses an electric liquid dispensing device for endoscope pretreatment. By setting a heating base inside the storage chamber, the water storage bottle can be placed on the heating base, and the heating temperature can be adjusted by the knob scale thermostat to achieve constant temperature heating of the water storage bottle. It also mainly solves the problem of constant temperature.

[0005] At present, when the existing technology flushes the endoscope, the cleaning liquid cannot be used in a quantitatively controlled manner, resulting in unnecessary waste.
