Real-time urine/body fluid monitoring system

Abstract

The invention discloses a real-time urine/body fluid monitoring system which comprises a clamp plate, at least one hook for hanging on a bed rail, an upper end drainage tube, a transparent tube, a lower end drainage tube, a collecting device, an infrared transmitter, an infrared receiver, an inlet switching device, an outlet switching device, a weighing sensor, a display and a single-chip microcomputer; the single-chip microcomputer receives an measurement instruction and controls the inlet switching device to open the inlet and the outlet switching device to close the outlet, so that urine/body fluid flows in the transparent tube, the infrared transmitter transmits infrared light, and the infrared receiver receives the infrared light and transmits a control signal to the single-chip microcomputer when liquid level reaches set distance; the single-chip microcomputer controls the inlet switching device to close the inlet and the outlet switching device to open the outlet; the weighing sensor detects weight of the urine/body fluid in the collecting device; the single-chip microcomputer calculates a weight value and the amount of urine/body fluid corresponding to the set distance, and urine specific gravity/body fluid specific gravity is obtained. The system can meter urine/body fluid and measure the urine specific gravity/body fluid specific gravity in real time.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a real-time urine / body fluid (wound drainage, pleural effusion, bile, gastric juice, cerebrospinal fluid, etc.) monitoring system for real-time monitoring of human urine or body fluid. Background technique [0002] Urine output is one of the important indicators to measure tissue perfusion and body fluid balance, and can reflect renal function, cardiac function, circulating blood volume, etc. Urine specific gravity determination is mainly used to understand the concentration and dilution functions of the kidneys, and can also be used for auxiliary diagnosis and condition monitoring of certain diseases. Urine specific gravity can fluctuate widely due to diet and drinking, sweating and urination. Therefore, for patients in the intensive care unit, the determination of urine volume and urine specific gravity is particularly important. Existing urine collection usually uses...
