technical field

The invention relates to the field of medical supplies, in particular to a precision urine volume meter.

Background technique

Urine output is a common parameter reflecting tissue perfusion and body fluid balance, and is an important part of monitoring various clinical indicators of patients. Urine output is the most direct and sensitive indicator reflecting the level of renal blood perfusion. The research results show that urine output has become an important observation index in the diagnosis and treatment of critically ill patients, and accurate urine output measurement can provide a reliable basis for clinical diagnosis and treatment. In order to ensure the accuracy of urine volume measurement, it is necessary to put forward high-quality requirements for the quality of clinical nursing operations. Clinically, indwelling catheters are used for major surgery, urinary retention, urinary incontinence and critically ill patients, and the urine is directly poured from the drainage bag into the measuring cup to accurately record the urine volume. Since the urine volume needs to be recorded repeatedly every day, nurses need to change gloves many times and open the drainage bag switch many times. The operation is cumbersome, not only time-consuming, but also increases the expenditure on consumables and the workload of nurses, and also increases the risk of retrograde infection.

At present, the method of using precision-measured disposable drainage bottles is the most accurate and convenient method of urine measurement. However, in view of the high price of precision drainage bottles, the use of them will increase the medical expenses of patients. General wards of hospitals cannot be widely used.
