Automatic urine specific gravity measuring recorder and measuring method thereof

Abstract

The invention provides an automatic urine specific gravity measuring recorder and a measuring method thereof. The recorder comprises a main body, a weighing barrel, a shunt collector, a single-chip microcomputer, a top weighing sensor and a display screen. The main body comprises a base, a supporting part and a top cover. The weighing barrel is arranged on the base; the shunt collector is erectedon the weighing barrel and is used for collecting part of urine to measure the specific gravity and diverting redundant urine into the weighing barrel. Urine of which the specific gravity is measuredflows into the weighing barrel and thus the urine specific gravity can be measured for many times in different time periods. The single-chip microcomputer and the top weighing sensor are arranged on the top cover, the single-chip microcomputer is electrically connected with the top weighing sensor, the top weighing sensor is used for sending buoyancy data measured by urine in the shunt collector to the single-chip microcomputer, and the single-chip microcomputer is used for calculating and converting the buoyancy data into urine specific gravity data, displaying the urine specific gravity dataon the display screen and storing the urine specific gravity data. The automatic urine specific gravity measuring recorder can automatically measure and store the urine specific gravity in each timeperiod, so that the workload of the nursing personnel and nurses is reduced.

Description

technical field [0001] The invention relates to the technical field of urine specific gravity measurement, in particular to an automatic urine specific gravity measurement recorder and a measurement method thereof. Background technique [0002] Urine is produced by the blood flowing through the kidneys after filtration and reabsorption, and the generated urine is mainly used to eliminate metabolites and excess water in the body. The urine volume excreted by a normal adult in 24 hours is 1000 to 2000 ml. If it exceeds 2500 ml, it is polyuria, which is often caused by excessive water intake by the body or decreased water reabsorption by the renal tubules (urine concentration disorder). Urine volume less than 500 ml is oliguria, and less than 100 ml is anuria, which is mainly related to too little water intake, excessive water loss (such as hemorrhage, severe burns and diarrhea, etc.) and decreased filtration rate of glomerular lesions , When the urine is produced and excreted...

Problems solved by technology

[0004] The existing urine specific gravity measurement usually uses a urine bag to collect a certain volume of urine at regular intervals for weighing, and then calculates the urine specific gravity. Someone needs to pay attention to the amount of urine in the urine bag every day. When the amount of urine reaches a certain It is necessary to pour out the urine, weigh it and make a record when making the volume. It is necessary to repeat the pouring, weighing, calculation and recording items many times a day, which increases the workload of the nursing staff and nurses. The measurement operation is cumbersome and the measurement accuracy is not enough
