Excrement sampling instrument for medical clinical laboratory

Abstract

The excrement sampling instrument comprises a sampling pipe, a sampling opening is formed in one side of the middle of the sampling pipe, a through hole is formed in the middle of a threaded cover, a guide pipe is inserted into the threaded cover through the through hole, and the upper end of the guide pipe is in an opening state and is provided with an elastic rubber bag; a sampling rod is fixedly connected to the center of the outer surface of the lower end of the guide pipe, the lower end face of the sampling rod extends to the position below the plane where the lower portion of the sampling opening is located, a spiral blade is fixedly arranged on the sampling rod in a winding mode, and an absorbent cotton column is jointly bonded between the lower surface of a connecting rod and the lower surface of a scraping ring. And the lower end of the absorbent cotton column extends to the inner bottom of the sampling pipe. In the application process, excrement in different states can be rapidly sampled, the sampling efficiency is improved, solid-liquid separation can be achieved in the sampling process for liquid excrement, and use is facilitated.

Description

technical field [0001] The invention relates to the technical field of sample sampling, in particular to a stool sampling device used in medical laboratory departments. Background technique [0002] In the process of medical testing, sampling and testing the feces of patients is a common and efficient testing measure, which can accurately reflect the patient's current physical state, disease conditions and other information according to the test results, which is helpful for doctors to be more accurate. Judging the patient's physical state and disease conditions, so as to help doctors to carry out accurate treatment. [0003] However, in the process of sampling feces, since the patients themselves are in a diseased state, the feces are in different states. For feces with different states, different samplers need to be used for sampling, which causes the inconvenience of stool sampling; especially For liquid stool, the existing sampling device cannot effectively separate sol...

Problems solved by technology

[0003] However, in the process of feces sampling, because the patient is in a state of illness, the state of the feces is different. For the feces of different states, different samplers need to be used for sampling, which causes the inconvenience of stool sampling; especially For liquid stool, the existing sampling device cannot effectively separate the solid and liquid during the initial sampling process, and further solid-liquid separation is required after the sample is obtained
