A bionic dual-drive device for reverse intestinal flora transplantation with magnets and wheat awns

Abstract

A bionic dual-drive reverse intestinal flora transplantation device with magnet and wheat awn, including a pipeline body with open head and tail ends, a sliding jacket and an internal magnet are arranged at the head end of the pipeline body, and the internal magnet is arranged on the pipeline body The upper end of the sliding jacket is closed, wrapping the inner wall of the pipeline body and the outer surface of the magnet in the body. The outer wall of the sliding jacket is provided with an imitation wheat awn structure, and the inner wall and the tail of the outer wall of the sliding jacket are respectively connected with pull lines. The tail end of the main body is provided with Velcro, and the Velcro is distributed on the inner and outer walls of the pipeline body. The pulling wires are connected and fixed on the Velcro, and the side wall at the head end of the pipeline body is provided with a side hole. The present invention can obviously shorten the time of catheterization, and can inject the bacteria-containing liquid after inserting into a deeper part, so as to ensure the curative effect, eliminate the discomfort brought by the traditional oral intestinal flora transplantation to patients, and at the same time avoid gastric juice and other effects on the bacterial flora activity. Influence, to achieve the purpose of injecting the liquid containing the intestinal flora to be transplanted through the lower digestive tract.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a bionic dual-drive reverse intestinal flora transplantation device of a magnet and awns. Background technique [0002] The intestinal flora is not only huge in number, but also particularly important in function. The intestinal flora not only participates in the energy metabolism of the human body, but also undertakes vital physiological functions in the immune system regulation mechanism. However, in the past few years, due to the application of broad-spectrum antibiotics, advanced age, long hospital stay, taking immunosuppressive drugs or previous infection history, etc., the normal structure of intestinal flora has been destroyed, and the self-organization of intestinal flora has been broken. The dynamic balance of regulation leads to the occurrence of various intestinal diseases, such as constipation, irritable bowel syndrome, inflammatory bowel disease, especially C...

Problems solved by technology

The nasoenteric tube is much thinner than the colonoscope. It is a kind of tube inserted into the intestine through the mouth. There are two obvious defects in the administration of the nasoenteric tube: the input of feces will make it difficult for the patient to accept the sensory and visual effects, and the The patient causes a great psychological burden; the slow speed of catheterization seriously affects the treatment process

The enema method is to insert a catheter from the anus through the rectum to perfuse the colon, but the insertion depth can only reach about 20cm, probably at the sigmoid colon

However, the lesions are mostly located in the ileocecal or jejunum, and the insertion depth of the enema method is far from meeting the treatment requirements.

In addition, due to the shallow insertion depth, the patient is likely to feel the desire to defecate and have a bowel movement after the feces are poured in, which will affect the treatment or even interrupt the treatment after the excretion.

Colonoscopy is widely used in the current research and experiments on intestinal flora transplantation. Although it can be inserted into a deeper part, the therapeutic effect is guaranteed, but the patient will obviously feel abdominal pain and distension

Moreover, there are great potential safety hazards, and the risk of perforation, bleeding, and cardiopulmonary-related complications is high.

Colonoscopy is very clumsy, extremely inconvenient to operate, time-consuming and laborious
