Abstract

The invention relates to urine storage liquid, a preparation method and a slice making device thereof. The urine storage liquid is prepared from the following ingredients in percentage by mass: 2 to 4percent of sodium citrate, 0.08 to 0.12 percent of sodium chloride, 0.03 to 0.05 percent of potassium chloride, 0.02 to 0.03 percent of calcium chloride, 20 to 30 percent of formaldehyde, 30 to 40 percent of ethyl alcohol, 1 to 2 percent of glacial acetic acid and the balance of distilled water. The invention also provides the preparation method of the urine storage liquid according to the claims. The slice making device of a urine inspection sample comprises a flat bottom tube, a tube cover and cover glass. The cost of the urine storage liquid is low; the preparation method is simple; the popularization and the use are convenient; urine cells can be fast and fixedly stored for a long period; the urine cell form is completely maintained; the urine inspection requirement on the effective cell quantity and quality can be met; the preparation method of the urine storage liquid is simple; no three-waste pollution is generated. The slice making device of the urine inspection sample is simple in structure and convenient to use.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a urine preservation solution, a preparation method and a tablet-making device thereof. Background technique [0002] Urine is an excrement of great significance. Changes in urine components reflect lesions in the urinary system and other tissues and organs. The accuracy of the test results is directly related to the diagnosis and treatment of diseases. Urine cytology is a pathological examination method used to detect malignant tumors of the urinary system. [0003] Urine is an unstable substance, and certain chemical changes will occur once excreted. The test results after storage for 6h, 12h and 24h are different from those just excreted. The main reason is that the urine sample is corrupted. Visible or intangible changes may occur from time to time, pH value may increase or decrease, color deepening, rancid smell, turbidity increase, bilirubin decrease or disappear, ketone ...
