Problems solved by technology

[0003] The above methods not only increase the workload of nurses, but also increase the risk of urine contact contamination
Moreover, the heavy workload of intensive care may also cause nurses to fail to measure on time, or due to various reasons such as human errors caused by shifts, missed inspections, missed records, and recording errors occur from time to time, causing delays in clinical judgment. or gross negligence

Abstract

The invention relates to a urine amount inspection instrument, and particularly discloses a weighing-type automatic urine measuring instrument. The weighing-type automatic urine measuring instrument comprises a microprogrammed control unit (MCU) master control circuit, an analog-to-digital conversion circuit, a data storage circuit, a display driving circuit and an alternating-current and direct-current power circuit, wherein the analog-to-digital conversion circuit, the data storage circuit, the display driving circuit and the alternating-current and direct-current power circuit are connected with the MCU master control circuit; the input end of the analog-to-digital conversion circuit is also connected with a pressure sensor; and the output end of the display driving circuit is also connected with a display screen. The weighing-type automatic urine measuring instrument is used for monitoring the urine amount data so as to simplify a urine amount measuring flow, the workload of a nurse is lowered, and the pollution possibility is reduced.

Description

technical field [0001] The invention relates to a urine volume detection instrument, in particular to a weighing type automatic urine meter for accurately measuring urine weight and displaying / recording intermittent urine volume results. Background technique [0002] Strict monitoring of urine output, especially hourly urine output and urine flow rate, has important clinical significance for closely observing the patient's condition, understanding the vital status of the body, and judging the outcome and prognosis of the disease. At present, manual intermittent static detection is still used clinically for urine volume detection of critically ill patients. Urine is collected with a urine collection bag at intervals, and a measurement scale is marked on the urine collection bag. quantity. However, the urine output results read by the scale of the urine bag often have a large error, and it has been reported in the literature that sometimes the error can be as high as 60%. Th...
