Device for measuring urine volume and pressure intensity of bladder and measurement and control method thereof

Abstract

The invention provides a device for measuring the urine volume and the pressure intensity of a bladder and a measurement and control method thereof. Each pipeline is controlled to be on and off, a control and information analysis system records the corresponding value of the increment or decrement of the bladder pressure intensity and the bladder volume on each time point in real time in the irrigation process and the urination process; then, the information is collected and counted by the control and information analysis system to obtain and store the corresponding relationship of the bladder pressure intensity and the bladder volume as well as a graph and a report. The device for measuring the urine volume and the pressure intensity of the bladder has the advantages of convenience in operation and control, low cross infection risk and small potential safety hazard.

Description

technical field [0001] The invention relates to a device for measuring the urine volume and pressure in the bladder and its measurement and control method, in particular to a device suitable for clinical patients with symptoms such as "urgency, frequent urination, and dysuria" to measure the urine volume and pressure in the bladder. A device for pressure and a method for its measurement and control. Background technique [0002] Measuring the pressure in the bladder and urine output can determine the causes of symptoms such as "urgency, frequency, and dysuria". [0003] Clinically, the safe intravesical pressure refers to the urinary pressure in the bladder as 40 cm water column. Exceeding this pressure value may cause upper urethral reflux, cause hydronephrosis, nephritis and other symptoms, and endanger the safety of upper urethra, kidneys and other organs. [0004] The pressure in the bladder is determined by factors such as urine volume in the bladder and bladder compl...

AI Technical Summary

Problems solved by technology

[0019] a) In the existing electronic measurement system, solenoid valves or solenoid reversing valves are mostly used as the switching devices of the pipeline system. The filling liquid and urination must pass through the pipeline in the valve body, which is difficult to disinfect and risks contamination also larger;

[0020] b) Each valve body is controlled by an electronic system. Once the electronic system or the valve body itself fails, the perfusion process will not be stopped, and the operator will not know, which may endanger the health of the patient;

[0021] c) Perfusate temperature not controlled
