Low-power-consumption automatic monitoring device for urine volume of patient

Abstract

The invention provides a low-power-consumption automatic monitoring device for urine volume of a patient and belongs to the field of automatic monitoring of urine volume of patients. The low-power-consumption automatic monitoring device comprises a liquid inlet electromagnetic valve, a liquid inlet electromagnetic valve driving circuit, a liquid outlet electromagnetic valve, a liquid outlet electromagnetic valve driving circuit, a full detection electrode, a full detection circuit, an evacuation detection electrode, an evacuation detection circuit, a urine collecting tube, a singlechip controlcircuit, a power supply management module, a data storage module, a wireless transmission module, a display module, a key control module and a clock module. According to the low-power-consumption automatic monitoring device for the urine volume of the patient, a divided and ruled mode is employed, urine of the patient is divided into unit volumes, then, counting is carried out, a product of a count value and the size of a unit volume is the urine volume of the patient, and the urine volume and urine flow rate per hour are calculated accordingly and are displayed, stored and sent. According tothe low-power-consumption automatic monitoring device for the urine volume of the patient, by employing a low-power-consumption design, the urine volume of the patient is monitored accurately, stablyand conveniently, and influence on urine volume monitoring caused by a urine concentration, a urination speed and urine bag posture changes is overcome.

Description

technical field [0001] The application belongs to the design field of an automatic patient urine volume monitoring device, and in particular relates to a low power consumption automatic patient urine volume monitoring device. Background technique [0002] Urine flow can not only directly reflect renal perfusion and renal function, but also indirectly reflect the hemodynamic state of the body. It is one of the effective indicators for evaluating circulating blood volume, cardiac function, and microcirculatory perfusion. Important physiological indicators for early identification. The urine flow indicators commonly used in clinical practice include urine flow per minute, urine flow per hour, 24-hour urine flow, and 48-hour urine flow. Accurate measurement of urine flow is of great significance for mastering the patient's condition, timely adjusting the treatment plan, and judging the outcome and prognosis of the patient's condition, and it can also greatly reduce the workload...

AI Technical Summary

Problems solved by technology

Affected by changes in urine composition, it is difficult to establish an accurate flow rate mathematical model, which needs to be calibrated before use, and the flow rate sensor is difficult to accurately monitor low flow rates
