Safe and sanitary low-cost residual urine drainage measuring system

Abstract

The invention discloses a safe and sanitary low-cost residual urine drainage measuring system. The safe and sanitary low-cost residual urine drainage measuring system comprises a drainage tube (1), a peristaltic pump (2), a urine collecting bag (3) and a microcontrol unit (6), wherein the drainage tube (1) is connected with an inlet of the peristaltic pump (2); an outer of the peristaltic pump (2) is connected with an inlet of the urine collecting bag (3); the urine collecting bag (3) is connected with a weighing sensor (5); a gravity signal output end of the weighing sensor (5) is connected with a signal input end of the microcontrol unit (6); and a signal output end of the microcontrol unit (6) is connected with the peristaltic pump (2) and a display (7). A creep pressure pipe on the peristaltic pump is disposable, so that the problem that the traditional negative pump is difficult to clean and disinfect is solved, and the safe and sanitary low-cost residual urine drainage measuring system is safe, sanitary and low in cost; the hanger type weighing sensor is convenient to use and is unlikely to be damaged; and the safe and sanitary low-cost residual urine drainage measuring system has the characteristics of high accuracy of the measuring result, high safety, simplicity in operation, high measuring speed and the like.

Description

technical field [0001] The invention relates to a safe and hygienic low-cost residual urine drainage measurement system. Background technique [0002] For men over 60 years old, the incidence rate of benign prostatic hyperplasia is as high as 30%. Among them, some patients have obvious voiding dysfunction, including incontinent urination, excessive residual urine volume, etc. In more serious cases, excessive residual urine volume Up to 400ml. In addition, some patients with nerve damage will experience disturbance of urination consciousness and large residual urine volume. It is well known that a large amount of residual urine will seriously damage the kidney function. Therefore, it is very important to understand the residual urine volume of patients with voiding disorders in clinical diagnosis. [0003] The traditional methods for measuring residual urine volume are mainly divided into two types: (1) Insert a drainage tube into the bladder through the urethra, and measur...

AI Technical Summary

Problems solved by technology

[0003] The traditional methods for measuring residual urine volume are mainly divided into two types: (1) Insert a drainage tube into the bladder through the urethra, and measure the urine with a measuring cup or cylinder after drainage. The drainage speed of ordinary drainage tubes is slow, and the drainage Sometimes there is a steady stream of urine flowing into the bladder from the upper urinary tract, so the drainage time is long, time-delayed and less accurate

(2) Three-dimensional B-ultrasound is used for measurement, and the measurement is completed by internal calculation. This method is not only expensive, but also has low accuracy

However, this solution has the following disadvantages: (1) The liquid flow sensor is placed in the drainage circuit. If it is used once, the cost is too high and the patient cannot accept it; if it is to be used repeatedly, it is very difficult to clean and disinfect

(2) The weighing device uses a pallet-type weighing sensor. During use, the sensor will be damaged if the operator does not pay attention, which is very inconvenient to use

(3) The electric valve is placed between the medium inlet of the negative pressure pump and the drainage tube. If the electric valve is used once, the cost is high and the patient cannot accept it; if it is used repeatedly, it must be cleaned and disinfected every time. Cleaning and disinfection not only Troublesome and difficult to meet hygiene standards
