Problems solved by technology

It is difficult for medical staff to accept the visual, olfactory and psychological aspects of preparing fecal suspension, and to ensure the activity of fecal bacteria, the extraction process must be completed quickly, because most of the intestinal flora are anaerobic bacteria, When medical personnel get the stool sample, the stool sample has been in contact with the air for a period of time, and it is very difficult to ensure anaerobic conditions during the extraction process, so the current extraction equipment is difficult to ensure the quality of fecal bacteria

Abstract

The invention discloses a device for extracting intestinal content flora, which includes a crushing device, a filtering device and a negative pressure device; There are annular grooves, and there are annular blades for use in the two annular grooves; there is a filter screen on the inner wall of the bottom of the crushing bucket, and the end surface of the filter screen is evenly distributed with sharp protrusions, which are located on the side wall of the crushing bucket above the filter screen. There is a rotating shaft covered with spikes; the sealing cover is provided with a circular groove with air holes, and the circular groove is provided with an air valve cover hinged with the sealing cover; the crushing bucket is filled with the diluent; A liquid outlet with an on-off valve is arranged on the side wall of the lower part of the barrel; the beneficial effect of the present invention is that the present invention is not only convenient to operate, but also collects feces samples in combination with a plastic sealed bag, reducing the contact time between the feces samples and the air as much as possible, improving Survival rate of fecal bacteria and therapeutic effect.

Description

technical field [0001] The invention relates to a medical extraction device, in particular to an extraction device for intestinal content flora. Background technique [0002] Fecal transplantation is a method to treat diseases by rebuilding intestinal flora, that is, the feces of healthy people are processed to obtain beneficial fecal bacteria liquid, that is, parasites such as eggs and other parasites are removed, and only useful flora is retained, and then made into enteric coating Capsules or in between orally. It is difficult for medical staff to accept the visual, olfactory and psychological aspects of preparing fecal suspension, and to ensure the activity of fecal bacteria, the extraction process must be completed quickly, because most of the intestinal flora are anaerobic bacteria, When the medical staff gets the stool sample, the stool sample has been in contact with the air for a period of time, and it is very difficult to ensure anaerobic conditions during the ext...
