Description
Technical Field
[0001] The utility model relates to the field of enteroscope sleeves, in particular to an outer sleeve for enteroscope examination. Background Art
[0002] An enteroscope is a medical device used for examining and diagnosing chronic gastrointestinal bleeding of unknown cause and various small intestine lesions. After the endoscope is used, it should be immediately cleaned to prevent dirt from solidifying and blocking the nozzle. It is necessary to use a full-channel irrigator to rinse the water injection and air pipes. Distilled water should be placed in the water supply bottle, and the water in the bottle should be changed and the bottle should be cleaned every day. Otherwise, a water film will form on the inner surface of the bottle, entering the nozzle and the air and water pipes to cause blockage. Regularly check the rubber ring in the water supply bottle and replace it at any time. The rubber ring of the water supply bottle will be deformed due to long-term use, causing the water supply bottle to lose its sealing performance and affecting water injection and air injection.
[0003] Currently, during enteroscope examination, the pipeline of the enteroscope is not convenient to push, and it is extremely inconvenient to use.
[0004] In view of this, in response to the existing problems, research and improvement are carried out to provide an outer sleeve for enteroscope examination, which has a reasonable structural design. The setting of the air pump interface enables doctors to easily inflate the air bag through an external air pump, and then can clamp the enteroscope.
