Description

Quantitative sampler for excrement

Technical Field

The utility model relates to an extract the excrement and urine sampling device technical field of calprotectin composition in the people's excrement and urine, more specifically the saying so relates to an excrement and urine quantitative sampler.

Background

Calprotectin is an important protein in the neutrophil and activated macrophage cytoplasm, is increased in content in many inflammatory conditions, and can be used as an acute inflammatory marker; in clinical practice, calprotectin in stool is often used to assess the degree of intestinal inflammation, to monitor the condition of patients after removal of crohn's disease, ulcerative colitis, or polyps, and to differentiate inflammatory bowel disease from irritable bowel syndrome when performing stool examinations.

While calprotectin is currently found in many places in the human organism, it includes: serum, saliva, cerebrospinal fluid and urine. But is easy to detect in feces, has stable components, can exist in feces for about 7 days at room temperature, is not easy to be destroyed by bacteria and various enzymes, and is not affected by diet. The detection of the calprotectin in the excrement is a simple, rapid, high-sensitivity, strong-specificity, cheap and non-invasive inflammatory bowel disease detection method, which has higher sampling quantity requirement on the excrement, but the problems of more complex operation, long sampling time, unsanitary sampling and incapability of quantifying the sampling quantity exist in the market at present due to the limitation of a sampling device.

Therefore, how to provide a quantitative sampler for feces is a problem that needs to be solved by those skilled in the art.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the above-mentioned technical problem among the prior art to a certain extent at least.

Therefore, an object of the utility model is to provide an excrement and urine quantitative sampler solves the sample complicacy, the long, unsanitary and the technical problem that can not the ration of excrement and urine sample detection calprotectin among the prior art.
