Stool collector capable of controlling stool collecting quantity

Abstract

The invention discloses a stool collector capable of controlling stool collecting quantity. The stool collector comprises an outer tube body and a sampling rod, and is characterized in that inner a thread is arranged on an inner wall of one end of the outer tube body; a sealing film is arranged at the other end of the outer tube body; an inner convex ring is arranged in the middle of the outer tube body; the inner convex ring divides an inner cavity of the outer tube body into two independent connecting cavities and a buffering cavity; buffering liquid is arranged in the buffering cavity; a threaded cap matched with the inner thread is arranged at one end of the sampling rod; an integrally thorn-like collecting head is arranged at the other end of the sampling rod; and the collecting headpenetrates through the inner convex ring and extends into the buffering cavity. The stool collector provided by the invention can effectively control the stool collecting quantity, enables stool samples to be in a sealed environment during inspection, and can ensure authenticity and accuracy of routine detection results of stool.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a stool collector capable of controlling the amount of stool collected. Background technique [0002] Clinical stool test is one of the three routine tests of clinical testing in medical units, namely blood routine, stool routine, and urine routine. There have been no strict requirements for stool samplers throughout history. Early containers included matchboxes and cartons, and up to now, most of them are plastic boxes or cups of various shapes and sizes. 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 above-mentioned sampling detection method has the following disadvantages: la...

AI Technical Summary

Problems solved by technology

The above-mentioned sampling detection method has the following disadvantages: large pollution, difficult to control the sampling volume, disputes and disputes over the sampling volume, and the stool samples are exposed to the air most of the time during the stool sampling process by medical personnel, which not only makes indoor The smell is strong, not hygienic enough, and the stool samples are easily contaminated during the inspection process, which cannot guarantee the authenticity and accuracy of the stool routine test results
