The automatic dynamic urine monitoring system belongs to the urine test project, which involves a set of bedside urine monitoring system and technology that can automatically monitor patients undergoing urinary catheterization, and is used to monitor the patient's urine output and urine biochemical indicators, and bladder smooth muscle training. . The system adopts a number of technologies and products, involving urine test strips, test strip storage bins, acquisition, transfer and positioning, mother-in-law urine bags to keep urine fresh, bladder smooth muscle training, urine sample extraction and loading, accurate weighing of urination, use Urine specific gravity is converted into accurate urine volume and recorded, urine detection obtains biochemical indicators and urine specific gravity, local data storage and wireless / wired batch timing transmission, or accepts instructions to complete specified operations, parameters are set once, and automatic continuous operation. The host controls all subsystems to monitor the patient's urination and urine biochemical indicators in real time, complete functions that cannot be realized by traditional methods, eliminate multiple sources of interference, avoid human errors, reduce manual work, and will not pollute operators, truly realizing automatic unmanned operation.
