Stool sampler

Abstract

The invention discloses a stool sampler, comprising a plastic container, a sampling rod and a connecting pipe. A dropping liquid nozzle end of the plastic container is sleeved with a dropping liquid nozzle cover; the mouth end of the plastic container is sealed and fixedly connected with the connecting pipe; the plastic container contains solution; a filter element is arranged in front of the dropping liquid nozzle in the plastic container; the dropping liquid nozzle cover is provided with a plug sealing the dropping liquid nozzle; the connecting pipe is sleeved on the sampling rod; and one end connected with the plastic container of the connecting pipe is provided with film sealing a pipe hole, and the other end of the connecting pipe and the sampling rod are in threaded connection; a front section of the sampling rod is a sampling unit and is provided with a sampling groove; and a middle section of the sampling rod is a thread section. The technical scheme provided by the invention has advantages of simple structure, low manufacturing cost, convenient usage, sample contamination reduction, and convenience for retention and removal of the sample solution.

Description

technical field [0001] The invention relates to a stool sampler. Background technique [0002] Clinical stool testing is one of the three routine tests in clinical testing in medical units. There have been no strict requirements on the stool sample sampler. The early containers included matchboxes and paper boxes. Up to now, most of them are plastic boxes of different shapes and sizes. or cup. When sampling, the sampler picks out with a bamboo or wooden stick or picks up with a plastic spoon, and then the medical inspector uses the same method to pick out a small amount of suspicious part of the sample from the container, and adds a drop of normal saline or buffer solution to make a microscopic examination. or other checks. The method of taking samples like this is very polluting and extremely inhumane. Disputes and disputes often occur between doctors and patients for the pollution of the container and the size of the sampling volume. Exposure to the air will make the in...

AI Technical Summary

Problems solved by technology

The above structure has the following problems: the solution in the liquid holding pipe flows into the plastic container through the central hole of the sampling rod, and the central hole of the sampling pipe is easily blocked during the sampling process, which will affect the solution entering the plastic container; the sampling rod is hollow The structure and the outer wall has a sampling groove, which is difficult to process; the liquid tube is made of elastic plastic, which is fixed with the plastic container and is easy to detach; the sample particles are easy to flow out from the drip nozzle of the plastic container, which is easy to affect the detection and cause pollution
