Pre-colonoscopy intestinal preparation apparatus

Abstract

The invention discloses a pre-colonoscopy intestinal preparation apparatus, comprising an anal insert tube. The left end of the anal insert tube is an arc blind end; a right end opening of the anal insert tube is provided with a sleeve balloon; the end, far away from the anal insert tube, of the sleeve balloon is provided with a vacuum aspirator; a connection hose of the vacuum aspirator is communicated with the sleeve balloon and includes the connection hose; the end, far away from the sleeve balloon, of the connection hose is provided with an aspiration ball; the aspiration ball is connectedwith a liquid inlet of a drainage bag through a connection tube; the lateral right end of the drainage bag is provided with a vacuum tube; the aspiration ball is a rubber balloon. The pre-colonoscopyintestinal preparation apparatus is simple in structure, generates negative pressure in the intestinal cavity according to the vacuum operating principle so as to guide out liquid dung in the intestinal cavity, thus providing further cleaning and improving operating efficiency; the pre-colonoscopy intestinal preparation apparatus takes less examination time, causes less pain to a patient, and isflexible and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an intestinal tract preparation device before colonoscopy. Background technique [0002] Colonoscopy is a method of inserting a colonoscope into the ileocecal or terminal ileum through the anus to observe colonic lesions from the mucosal side. The safest and most effective method is that intestinal preparation is an important step before colonoscopy. Insufficient intestinal preparation before colonoscopy will cause fecal water in the intestinal cavity to cover the intestinal mucosa, and feces will pollute the mirror surface and affect the Observations during the examination may lead to missed diagnosis and misdiagnosis. The clean intestinal tract can be smoothly entered into the endoscopy, colonic mucosa observation, accurate biopsy tissue specimens and colonoscopic nodule and rectal membrane lesion operations (such as polyps, early digestive tract cancer EMR and ESD sur...

[0002] Colonoscopy is a method of inserting a colonoscope into the ileocecal or terminal ileum through the anus to observe colonic lesions from the mucosal side. The safest and most effective method is that intestinal preparation is an important step before colonoscopy. Insufficient intestinal preparation before colonoscopy will cause fecal water in the intestinal cavity to cover the intestinal mucosa, and feces will pollute the mirror surface and affect Observations during the examination may lead to missed diagnosis and misdiagnosis. The clean intestinal tract can be smoothly entered into the endoscopy, colonic mucosa observation, accurate biopsy tissue specimens and colonoscopic nodule and rectal membrane lesion operations (such as polyps, early digestive tract cancer EMR and ESD surgery, etc.) and other basic conditions for smooth progress. At present, cleansing enema and oral drug catharsis are commonly used methods for cleaning the intestinal tract in clinic. Although they basically meet the requirements of cleaning, they still cannot achieve the desired effect. Unclean, more feces accumulate in the intestinal cavity, which affects observation, increases examination and operation time, and reduces work efficiency
