Technical Field

The invention relates to the technical field of medical instruments, in particular to a specimen signing device for odor isolation.

Background

Urine examination is a medical detection method, and includes conventional analysis of urine, detection of visible components in urine (such as urine red blood cells, leukocytes, etc.), quantitative determination of protein components, and urease determination. Urine examination has very important values for clinical diagnosis, judgment of curative effect and prognosis, and urine examination items are different, and the requirements and treatment for urine specimen collection are also different. All urine samples should be collected using a clean container; the urinary sediment microscopic examination is to leave the midstream urine (morning urine) of the first urine after getting up in the morning and also to leave the midstream urine of random urine in principle, and the morning urine specimen is also suitable for urine other item examination (except 24h urine examination items); the renal tubule concentration and dilution function measurement needs to be performed after water deprivation and fasting for 12h, then urine deprivation is performed, water deprivation and fasting are continued for 1h, and urine in 13h is reserved for detection; when the renal tubule acidification function is measured, liquid paraffin is added into a urine retention container in advance; before the urine specimen is left for 24h, a preservative is added into the container or the container is placed in an environment at 4 ℃. However, the tube wall of the sample tube is prone to retain urine during the urine collection process, and odor is emitted during the detection of the urine in the sample tube.

Therefore, the sample signing device for odor isolation is provided, firstly, whether residual urine exists outside the sample tube can be distinguished, and the residual urine is cleaned, and secondly, odor emission is avoided aiming at the sample tubes with different odor concentrations.
