Simulation and analysis device for physiological processes of urine storage and emiction of bladder

Abstract

The invention provides a simulation and analysis device for physiological processes of urine storage and emiction of the bladder, comprising an artificial bladder, an artificial urethra, a pelvic cavity sink, an extrusion device, a pressure device, a perfusion device, a urine recovery device, a pressure measuring device and a flow metering device. The artificial bladder is used for simulating thefeature that the bladder changes volume along with the liquid capacity and realizing the function of urine storage; the artificial urethra used as a channel for discharging liquid in the bladder; thepelvic cavity sink is used as the environment for containing organs of the bladder, and the like; the extrusion device is used for simulating extrusion caused by the peripheral organs of the bladder to the bladder; the pressure device is used for simulating the shrinkage of detrusor of the bladder so as to realize the function of emiction of the bladder; the perfusion device is used for accurately measuring and displaying the liquid amount perfused to the bladder in real time; the urine recovery device is used as liquid reserve of liquid pumping of the perfusion device and for collecting the liquid discharged from the urethra so as to facilitate recycling; the pressure measuring device is used for measuring and displaying inner pressure of the bladder and the inner pressure of a pelvic cavity in real time; and the flow metering device is used for measuring and displaying the flow of the liquid passing through the urethra in real time. The invention can realize the physiological processes of urine storage and emiction of the artificial bladder, analyzes the physiological process by controlling and monitoring urine dynamical parameters of bladder volume.

Description

technical field [0001] The invention relates to the field of biomedical engineering research, and more specifically relates to a device capable of simulating the bladder and its surrounding organs and quantitatively analyzing the physiological process of bladder urine storage and urination by controlling and monitoring urodynamic parameters. Background technique [0002] In today's society, the incidence of urinary system diseases is extremely high among middle-aged and elderly people, among which lower urinary tract diseases account for a large proportion. These patients suffer from both physical and mental pains. For example, for patients with urinary incontinence who are bedridden for a long time, because they cannot urinate spontaneously, it will bring a lot of inconvenience in life and cause a series of complications. The hospital will conduct a series of urodynamic analysis on patients with urinary system diseases, such as bladder compliance, urine flow rate during uri...

Problems solved by technology

[0012] In order to solve the problems that the error of the current ultrasonic volume measuring instrument cannot be scientifically explained and the functionality of the artificial bladder cannot be effectively evaluated, the present invention provides a method that can more realistically simulate the physiological process of bladder storage and urination and improve its urinary function. A device for quantitative analysis of kinetic parameters, the device:
