Description

Technical Field

[0001] The utility model relates to a colorimetric card for a mixture of blood and urine. Background Art

[0002] At present, the commonly used methods for vaginal bleeding assessment in the department are area measurement, weighing measurement and visual measurement. According to the clinical progress of vaginal bleeding assessment, the methods for vaginal bleeding measurement can be roughly divided into: ① weighing method; ② visual measurement method; ③ hemoglobin measurement; ④ area method; ⑤ volume method; ⑥ shock index method.

[0003] In the above-mentioned prior art, visual estimation is more convenient for assessing the amount of bleeding and is often chosen, but it is subjective and has poor accuracy. When there is 1 ml of blood in 1000 ml of urine, the urine color change can be observed with the naked eye (gross hematuria). Therefore, when the patient has vaginal bleeding, but the vaginal bleeding is mixed with urine when urinating, and the amount of bleeding cannot be accurately recorded, the visual estimation method often misjudges the patient's vaginal bleeding. When a patient with vaginal bleeding goes to the toilet, the vaginal bleeding is often mixed with urine. In view of this situation, how to estimate the amount of bleeding by visual estimation is a major difficulty in clinical work. Utility Model Content
