Description

Technical Field
The invention belongs to the technical field of endoscope cleaning, and particularly relates to an endoscope treatment method.
Background
In the process of endoscopy and operation, blood, mucus, tissue debris and the like of a patient can enter and remain in an endoscope pipeline, so that after the endoscope is used each time, medical staff need to clean liquid, residues and the like on the inner wall of the endoscope pipeline by using a cleaning brush.
The existing endoscope cleaning brush generally comprises a flexible brush rod with a certain length, and the front end of the flexible brush rod is provided with bristles. When in use, the suction pipes are respectively connected to the front end of the endoscope, the original path is returned and drawn out, and the cleaning is repeated for a plurality of times; then from the suction pipeline to the endoscope joint, the original path is returned and drawn out, and the cleaning process of the endoscope pipeline is completed by repeating the entering and the exiting for several times. The problem that the current endoscope cleaning brush exists generally is following, because endoscope pipeline is tortuous and long, the soft brush-holder stud itself of endoscope cleaning brush is thinner, stretch into the endoscope pipeline when brush head part, even when the soft brush-holder stud is rotated to the outside, the brush head part of front end also is difficult to rotate, the brush hair forms non-contact area easily between the inner wall of inner mirror pipeline compression setting back and endoscope pipeline, when the endoscope is drawn round and round, the strip region that the endoscope pipeline inner wall was not brushed easily forms, can not take dirt and liquid out the pipeline completely, consequently need take out completely when actually wasing and again alternate the angle and stretch into and wash many times repeatedly again, and the work load has been increased, need a large amount of operating time. And because the condition of the inner wall of the endoscope pipeline cannot be observed, whether the endoscope pipeline is cleaned or not cannot be judged, and the endoscope pipeline is difficult to ensure clean even if the endoscope pipeline is repeatedly cleaned for many times.
The endoscope needs to be dried after being cleaned, and currently, the drying of the endoscope in hospitals at all levels mainly comprises the following two methods: one is drying by using a system disinfection drying device carried by a full-automatic endoscope cleaning and disinfecting machine, and the drying effect is good in the mode, but the device is expensive and has low popularity; the other method is to use a high-pressure air gun for drying, and the method has the advantages of low cost, time and labor waste and poor effect. In addition, because the endoscope pipeline is slender and narrow, no matter which type of drying is adopted, the drying degree in the endoscope pipeline cannot be detected, and the drying degree can not be ensured to meet the requirement.
In addition, a plurality of cavities are arranged in the endoscope and used for containing electric wires, data lines, optical fibers or other components needing water prevention, so that leakage-proof detection is often needed to be carried out on the cavities before use, and the current endoscope leakage detection methods mainly comprise two methods. One is a dry test method: inflating an endoscope by using a manual Fuji pressurizing ball, and then judging whether air is leaked or not by observing air pressure change; the mode has the following problems that manual pressurization is inconvenient to directly inflate the endoscope, initial pressure is difficult to control, detection is inaccurate, interfaces of the endoscopes with different specifications are different, and the phenomenon of air leakage is easy to occur. Another method is a wet method: inflating the endoscope, submerging the endoscope in the water tank, observing whether bubbles are generated in the water tank, and if the bubbles are generated, determining that the endoscope is damaged; the method is inconvenient to operate, the inner cavity of the endoscope is small in size, few gas is stored, if gas leakage occurs, the gas leakage is likely to be completed before the endoscope is put into water, so that bubbles cannot be observed.
