Description

Clinical laboratory's urine sample sterilization processing apparatus

Technical Field

The invention belongs to the technical field of medical equipment of clinical laboratory, and particularly relates to a urine sample sterilization treatment device for clinical laboratory.

Background

The urine examination comprises routine analysis of urine, detection of visible components in urine (such as urine red blood cells, white blood cells and the like), quantitative determination of protein components, and urease determination. Urine tests have important values for clinical diagnosis, judgment of curative effect and prognosis.

Urine examination items are different, and the requirement for collecting and handling urine specimens is also different. All urine specimens 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 is excreted, water deprivation and fasting are continued for 1h, and the 13 th urine 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 ℃.

When the urine specimen is kept, special situations should be noticed, wherein ① female patients should avoid taking the urine specimen in menstrual period, ② naked eye hematuria specimen should not be subjected to urine examination (except urine sediments), ③ patients should take the specimen after stopping taking the medicine if the medicine is used for affecting the urine examination, and ④ patients should be ordered to take the urine specimen after the urine is clarified if the medicine is chyluria.

The urine specimen should be inspected in time (within 2 h) after collection to avoid bacterial reproduction, protein denaturation, dissolution of visible components, etc. When the container is transported for a long distance, the container is placed in a covered container to avoid pollution caused by splashing, and the container is stored in a special container for conveying samples to avoid strong light irradiation, so that substances such as urobilinogen are prevented from being reduced due to decomposition or oxidation of light irradiation. After the sample is processed, the sample and the container are put into an Aierfeng (50 mg/tablet of available chlorine) effervescent tablet, the concentration of the solution reaches 2000mg and L of available chlorine, the mixture is evenly stirred and then acts for 2 to 4 hours, and then the mixture is put into a water-tight yellow medical garbage bag for storage and centralized burning. Therefore, the conventional destroying process is complex, needs independent environment and personnel, and has higher requirements on the condition and personnel arrangement of the clinical laboratory.
