Problems solved by technology

Modern fecal bacteria transplantation technology is mainly the method of instrument intervention, such as gastroscopy, gastric tube, colonoscopy, jejunal tube, etc. The treatment of diarrhea-type IBS and ulcerative colitis requires multiple transplants, and each time the fecal flora needs to pass through the catheter After passing through the stomach and duodenum, it is injected into the distal end of the duodenum. The process is complicated, the patient has certain pain, and the application is limited.

Abstract

The invention provides a drug-releasing capsule. Releasing of substances such as coprophilous fungi, therapeutic drugs, markers and food in the intestinal tract is remotely controlled. The drug-releasing capsule comprises a control cabin, a first drug-releasing cabin and a second drug-releasing cabin, and the control cabin comprises a wireless receiving module, a miniature battery and two microprocessors. After the drug-releasing capsule arrives at the gastrointestinal tract, when the control cabin receives in-vitro triggering signals for the first time, the first drug-releasing cabin releasesdrugs, and when the control cabin receives in-vitro triggering signals for the second time, the second drug-releasing cabin releases the drugs. By means of the drug-releasing capsule, the drugs can be released twice, and the drug-releasing capsule is free of invasion and pain and easy to operate.

Description

technical field [0001] The invention relates to a medical device, in particular to a medicine-releasing capsule, which releases substances, such as feces bacteria, therapeutic drugs, markers, food, etc., from the capsule that is swallowed by remote control outside the body. Background technique [0002] Existing remote-controlled drug-release capsules are mostly used in human drug absorption research and new drug development. Remote-controlled drug-release capsules can release drugs directly to the patient under the trigger of in vitro release instructions. The whole process is completely non-invasive. On the other hand, it can obtain higher drug concentration and drug utilization rate at the patient, which has important application value in clinical treatment. However, there is no clinically available electronic capsule for treatment, and the remote drug release can only release the drug once. [0003] Fecal microbiota transplantation (FMT), also known as fecal microbiota ...
