Device and method for evaluating and detecting intestinal preparation of patient before enteroscopy

Abstract

The invention discloses a device and method for evaluating and detecting intestinal preparation of a patient before enteroscopy. The device comprises an instrument box, a sample fixing frame, a turbidity measuring unit, a signal processing unit and an image sensor, and the turbidity measuring unit comprises a light emitting unit and a light receiving unit; the signal processing unit is connected with the turbidity measuring unit and is used for analyzing and calculating the light transmissivity of the sample in the sample cup and evaluating the turbidity of the sample according to the light transmissivity; when the turbidity of the sample does not meet the standard, an unqualified indication is directly given; the turbidity of the manure liquid can be objectively judged according to the detected light loss rate of the manure liquid, whether large solid residues exist in the manure liquid or not is judged by manufacturing the sample cup with the small protrusions with the safe aperture and simulating the method of sucking the manure liquid through an enteroscope, the requirement for intestinal tract preparation is standardized, and the detection accuracy is improved. The colonoscopy failure rate and the colonoscopy damage rate are reduced; and the postoperative secondary infection opportunity is reduced.

Description

technical field [0001] The invention relates to the technical fields of colonoscopy examination and treatment, colonoscope structure, optical technology, laser technology and pressure pump, and further relates to a detection device and method for evaluating and detecting intestinal tract preparation of patients before colonoscopy. Background technique [0002] Colonoscopy includes colonoscopy, enteroscopy, capsule endoscopy, etc. It is an endoscope that enters the intestine through the anus or through the mouth, and performs direct vision inspection of the small intestine and colon intestines. It can not only clearly observe the lesions in the intestinal tract, but also perform Biopsy of intestinal mucosal lesions, resection of lesions, hemostasis, vascular ligation, sclerosis, intestinal dilation, stent placement and other treatments and treatments are widely used clinically. At present, it has been listed as a routine physical examination item, and it has demonstrated the ...

AI Technical Summary

Problems solved by technology

[0004] At present, the workload of colonoscopy is heavy, and the pre-medication of patients’ intestinal preparation is a mechanized process. It is difficult for doctors to design individualized drug regimens for each patient’s intestinal preparation and to teach the intestinal preparation to meet the standards.

Constipation patients are not clear about the regular dose of laxatives. Some patients induce vomiting after taking laxatives, and the intake of laxatives is insufficient. Examination, some of the remaining water in the toilet dilutes the stool, which misleads the patient's judgment, resulting in as many as 16.7% of patients with poor intestinal preparation, feces or fecal liquid blocking, unable to achieve high-quality inspection goals, even nearly 1.3% % of patients had too many formed feces after inserting the endoscope and could not complete the observation of the whole colon, so they gave up the examination early

Resulting in wasted resources, financial loss and frustration for patients

[0005] In addition, the structural characteristics of the colonoscope also have high requirements on the cleanliness of the intestinal tract. Fecal fluid containing a small amount of fecal residue in the intestinal tract can be sucked out of the intestinal tract through the suction tube of the colonoscope with a diameter of 2.8mm. Large-volume residues may block the suction pipe of the colonoscope, requiring manual dredging or even returning to the factory for repair, resulting in short-term stoppage of the colonoscope, wear and tear of the colonoscope, and maintenance troubles
