Bladder urine flow turbulence shearing stress simulation system

Abstract

The invention discloses a bladder urine flow turbulence shearing stress simulation system. The bladder urine flow turbulence shearing stress simulation system is characterized in that the bladder urine flow turbulence shearing stress simulation system includes an imitation human body bladder model container, an electromotor stirring instrument, a urine storer, a waste liquid storage bag, a first peristaltic pump, and a second peristaltic pump, wherein the imitation human body bladder model container is a spherical glass bottle; a stirring rod mounting port is formed in the upper end of the spherical glass bottle, and a urine inlet and a urine outlet are formed in the lower end of the spherical glass bottle; a stirring rod connected with the electromotor stirring instrument is inserted intothe spherical glass bottle from the stirring rod mounting port; the urine inlet is connected to the first peristaltic pump through two medical silicone pipes, and the first peristaltic pump is connected with the urine storer; and the urine outlet is connected to the second peristaltic pump through a medical silicone pipe, and the second peristaltic pump is connected with the waste liquid storagebag. The bladder urine flow turbulence shearing stress simulation system establishes turbulence shearing stress through multi-dimensional simulation and has great potential in incidence of bacterial biofilm infection morbidity study application in a bladder.

Description

technical field [0001] The invention relates to a device system for simulating bladder urine storage and urination, in particular to a bladder urine flow turbulent shear stress simulation system, which belongs to the technical field of biomedical engineering. Background technique [0002] The incidence of urinary system diseases is extremely high in the middle-aged and elderly people, which seriously affects the quality of life of the middle-aged and elderly people and poses a huge burden to the society. Urinary system diseases are mainly lower urinary tract diseases, and the bladder is an organ for storing urine. In patients with urinary system diseases, once the bladder is affected, the impact is particularly serious. [0003] Existing medical technologies usually take certain active measures to alleviate the symptoms of urinary system diseases in order to improve the quality of life of patients and promote rapid recovery from diseases. However, the research on the change...
