Portable excrement collecting device

Abstract

The invention relates to the technical field of medical instruments, in particular to a portable excrement collecting device which comprises a bag body, an air storage bag and a three-way valve. The bag body is used for collecting excrement; the air storage bag is arranged on the bag body, and an air inlet switch used for filling nitrogen into the air storage bag is arranged at one end of the air storage bag. A first interface of the three-way valve is connected with the other end of the air storage bag; air in the bag body can be exhausted by communicating the second connector and the third connector of the three-way valve, then the first connector and the second connector are communicated to enable nitrogen to be exhausted into the bag body from the air storage bag so as to make an oxygen-free environment in the bag body, and finally all the connectors are closed to prevent air from entering the bag body so as to keep the oxygen-free environment. According to the invention, excrement of a donor can be collected and stored in an oxygen-free environment, so that the activity of anaerobic bacteria is ensured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable stool collection device. Background technique [0002] There are a lot of microorganisms in each human body, which together form a constantly changing state, which we call the microecology, and in the intestinal tract, it is called the intestinal microecology. Microbial bacteria account for more than 99%, and there are thousands of bacteria identified at present, so the intestinal flora is usually used to represent the intestinal microecology, and the intestinal flora interacts with the body. Therefore, a patient with intestinal flora imbalance needs healthy flora to be transplanted into the intestinal tract to change the original state. Fecal microbiota transplantation is to transplant the functional flora in the feces of healthy people into the patient's gastrointestinal tract, and rebuild new intestinal flora in the patient's gastrointestinal tract, so as t...

Problems solved by technology

[0003] At present, the collection and transfer of fecal samples is one of the important links in clinical and scientific research of fecal bacteria transplantation. The correct collection and transfer are directly related to the effect of fecal bacteria transplantation, and anaerobic bacteria are the most important in human intestinal microbes. However, at this stage, most hospitals are not equipped with special fecal collection equipment for fecal transplantation, which cannot ensure that the feces are in an anaerobic environment during the transfer process, resulting in the loss of fecal bacterial activity and the proportion of bacterial flora.
