Description

Multifunctional intestinal tract cleaning device

Technical Field

The invention relates to the technical field of medical instruments, in particular to an intestinal tract cleaning treatment device, and specifically relates to a multifunctional intestinal tract cleaning device.

Background

The intestinal tract (Intestine) is the largest digestive organ in the human body, and has very complex physiological structure and functions, and the main functions of the intestinal tract include digestion, absorption, immunity, metabolic transport and the like. The physiological structure of the Intestine can be roughly divided into Large Intestine (Large Intestine) and Small Intestine (Small Intestine), compared with the Small Intestine, the inner wall of the Large Intestine is smooth and has no villus tissue, and the caecum and the colon wall of the Large Intestine also have saccular colon bag structure; the main functions of the device are to recover water, secrete mucus, lubricate stool passage and absorb partial nutrients; the common peristalsis action of the small intestine and the large intestine pushes digestion residues to be discharged to the Rectum and the Anus, the physiological structure of the large intestine along the moving direction of the food residues can be sequentially divided into a Cecum (Cecum), an Ascending Colon (Ascending Colon), a Transverse Colon (Transverse Colon), a Descending Colon (Descending Colon), a Sigmoid Colon (Sigmoid Colon) and a Rectum (Rectum), and the excrement is discharged out of the body under the control of the Anus (Anus) at the end of the Rectum.

In clinical practice, intestinal tract dysfunction can be caused by various reasons, symptoms such as abdominal distension, abdominal pain, local lesion, fistula and the like are caused, a colonoscope is clinically needed to be used for examining the inside of the large intestine for the needs of diagnosis or treatment, the inner walls of the colon, the rectum and the anal canal can be directly observed through colonoscope examination, whether lesion conditions exist in all parts can be judged, and tissue biopsy samples can be taken by using auxiliary instruments or corresponding treatment can be carried out according to the examination conditions; before the treatment, the cleaning enema treatment needs to be carried out on the interior of the colon so as to ensure that food residues in the colon are cleaned up without affecting the inspection effect; the intestinal tract cleaning is classified into grades A, B, C and Ding Sige according to the condition of the intestinal tract with or without feces: the grade A standard means that the intestinal tract of a patient has no excrement and only a small amount of clear liquid; the grade B standard is that only a small amount of feces or a small amount of clear liquid exists in the intestinal tract of a patient, and the endoscopic observation and observation cannot be influenced generally; the grade-C standard means that a medium amount of liquid dung is discontinuously arranged in each section of the intestinal tract, but the liquid dung can be observed smoothly in modes of sucking, changing body positions and the like, and the inspection result is not influenced; grade D indicates that the intestinal tract preparation is unqualified, the intestinal tract of a patient is unclean, a large amount of turbid liquid dung or loose excrement exists, the patient still cannot observe smoothly through sucking or changing body positions, the inspection result is seriously influenced, and the specific condition in the intestinal tract cannot be observed smoothly; therefore, the intestinal tract cleaning effect is of great significance for examination and treatment.

In the existing devices related to intestinal tract cleaning, for example, patent with publication number CN204351996U discloses a tube bag dirt control kit for nursing patients with fecal incontinence, which mainly comprises a silica gel catheter assembly, a fecal liquid collecting bag and a drainage bag; the top end of the catheter component is placed in the body, the bottom end of the catheter component is connected with the liquid dung collecting bag, and meanwhile, the catheter component is connected with the drainage bag. According to the technical scheme, a plugging air bag and a fixing air bag are arranged at the position where equipment is connected with the anus of a patient, and a first flushing port and a second flushing port of a drainage tube respectively flush the inner wall of an intestinal tract and the inner wall of the drainage tube so as to achieve a good discharging effect; however, the fixing bag arranged at the anus influences the contraction of the anal sphincter under the normal state due to larger size, causes discomfort or perianal diseases due to continuous stimulation, and the arrangement position and the arrangement angle of the flushing opening are single, so that the wrinkled structure in the intestinal tract cannot be cleaned sufficiently. The patent with the publication number of CN204218871U discloses an intestinal content cleaner, wherein a rotating device is arranged in a working component inserted into an anus to be matched with water spraying and stirring to refine hard excrement, so that the refined pulp can be effectively discharged, but the rotating device arranged in the cleaner is limited in arrangement position and is difficult to directly contact with the hard excrement, the refining effect is general, a fold structure exists in a colon, and potential safety hazards exist when the rotating device is possibly involved in intestinal inner wall tissues.

The patent with the bulletin number of CN112472900B discloses an intestinal tract cleaning apparatus used before enteroscopy in gastroenterology, which comprises a front barrel, a connecting soft ring and a rear barrel and further comprises an angle adjusting mechanism, wherein the front barrel and the rear barrel are connected through the connecting soft ring, a cleaning pipeline mechanism is arranged in the rear barrel, a water flow adjusting mechanism is arranged at the lower part of the cleaning pipeline mechanism in the rear barrel, a supporting block is arranged in the front barrel, a liquid outlet pipe is arranged on the left end face of the front barrel, a return sheet is arranged at the lower end of the connecting soft ring, a liquid inlet pipe matched with the cleaning pipeline mechanism is communicated with the right end face of the rear barrel, and a supporting plate is transversely arranged in the rear barrel. The technical scheme of the patent is provided with an angle adjusting structure and a water flow adjusting mechanism, the device is compact in structure and can be operated by one hand to adjust the flow rate and the flushing angle of flushing liquid; however, the device has a limited angle range, is not suitable for cleaning deep structures of intestinal tracts, lacks feedback information in manual adjustment operation, controls the flushing force and the flushing angle by experience and intuition, and has poor applicability.

Based on the analysis, in the existing device for cleaning the intestinal tract, the position and the angle of the flushing structure are difficult to be set to cope with the fecal material with complicated structure and variable properties in the intestinal tract, especially the positions of a fold structure, a colon bending structure and the like formed by a colonic belt, a colon bag, a fat lobe and the like; the suction recovery structure and the flushing structure of the existing device do not form closed treatment so as to improve the enema operation environment and improve the operation quality; meanwhile, the existing device is less provided with feedback control of the cleaning process, cleaning operation is carried out only by experience feeling, and cleaning parameters such as a flushing position, a flushing speed, a suck-back pressure and the like are controlled according to the cleaning state information in the intestinal tract so as to improve the accuracy of intestinal tract cleaning and the applicability of the device.
