Stool sampler

Abstract

The invention discloses a stool sampler, comprising a plastic container, a sampling rod, a connecting piece, a liquid containing tube and a dropping nozzle cover. The plastic container and the connecting piece are in screw connection; the liquid containing tube is sleeved outside the connecting piece and the plastic container; the connecting piece comprises an external thread part, a large diameter part, a small diameter part and a broken rod part; the external thread part is connected with screw at the port of the plastic container; the large diameter part cooperates with a tube nozzle section of the liquid containing tube; the outer circumference of the large diameter part is provided with an annular buckle, which cooperates and clamps with an annular groove arranged on the inner wall of the tube nozzle section of the liquid containing tube; the small diameter part and a necking part of the liquid containing tube fit closely and are in sealing connection; the broken rod part is arranged in a liquid containing chamber of the liquid containing tube; a central hole of the connecting piece runs through the external thread part, the large diameter part, the small diameter part and until the broken rod part; and an axial rib end of the sampling rod is inserted into the central hole of the connecting piece. The technical proposal has advantages of simple structure, low manufacturing cost, convenient usage, reduced sample contamination 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
