[0003] At present, in the urinary medical research and clinical training, the commonly used urinary system pressure test method includes urodynamic detection and non-invasive monitoring technology. The instrument of urodynamic detection is based on the principles of fluid mechanics and electrophysiology, and measures the indexes such as intravesical pressure and detrusor pressure through methods such as inserting pressure measuring catheter and rectal pressure measuring tube; the non-invasive monitoring technology such as electrical bioimpedance technology is used to measure bladder urine volume (BUV), and the impedance change is measured by placing electrodes on the abdomen to infer the filling state of the bladder.

The high-bionic human urinary system model in the embodiment further comprises a fixing device, specifically a support 16, for fixing the kidney model 11.

[0028] In the embodiment, the water pump 21, the gas pump 22 and the manual control device 23 are connected with the sealed cavity of the prostate model 15 through pipelines respectively; the water pump 21 injects physiological saline into the sealed cavity of the prostate model 15 through the pipeline to dynamically simulate the volume expansion of the gland; the gas pump 22 fills gas into the sealed cavity of the prostate model 15 through a quick-connection gas pipeline to simulate the hardening or fibrosis of the gland; the manual control device 23 can directly inject physiological saline and gas into any position of the high-bionic human urinary system model 1 through a syringe to realize fine adjustment of local pressure.

[0029] The mobile terminal in the embodiment is connected with the pressure sensor 131 through a signal line, and the mobile terminal in the embodiment is a computer terminal 33; the intelligent data acquisition and control system 3 further comprises a data acquisition card, the data acquisition card is connected with the pressure sensor 131 through a signal line, and the data acquisition card is connected with the computer terminal 33 through a USB interface.

[0030] When the urinary pressure test simulation environment experimental system device is used, first, the two groups of kidney models 11 are fixed on the bracket 16, the two groups of ureter models 12 are connected with the bladder model 13, and then the bladder model 13 is connected with the prostate model 15 through the urethral model 14, wherein the urethral model 14 penetrates through the sealed cavity of the prostate model 15, and the interfaces are ensured to be sealed; the pressure sensor 131 is connected with the data acquisition card through a signal line, and the data acquisition card is connected with the computer terminal 33.

[0031] The embodiment further provides an operation method of the urinary pressure test simulation environment experimental system device, and the operation method comprises the following steps: The spiral adjusting valve at the end of the urethral model 14 is closed, the water pump 21 is started to inject liquid into the sealed cavity of the prostate model 15, and the bladder pressure of the pressure sensor 131 in the bladder model 13 from filling to emptying is obtained; The spiral adjusting valve at the end of the urethral model 14 is closed, the air pump 22 is started to inject gas into the sealed cavity of the prostate model 15, and the bladder pressure of the pressure sensor 131 in the bladder model 13 when the pressure rises to a stable state is obtained; The ureter model 12 with a different inner wall size and the prostate model 15 with a different cavity size are replaced, the above-mentioned operation of starting the water pump 21 to inject liquid into the sealed cavity of the prostate model 15 is repeated, and the influence of different prostate diseases on the urination function of different patients is simulated and observed.

[0032] The operation method of the urinary pressure test simulation environment experimental system device in the embodiment is specifically implemented as follows: The screw adjustment valve at the end of the urethral model 14 is in the closed state (simulating the contraction of the urethral sphincter during urine storage), and the water pump 21 is turned on to inject physiological saline into the sealed cavity of the prostate model 15. The physiological saline gradually fills the sealed cavity of the prostate model 15, causing the sealed cavity to expand. The expanded sealed cavity uniformly presses the urethral model 14 passing through it, causing the inner diameter of the urethral model 14 to significantly decrease, and the flow resistance in the urethra to increase.

[0033] Filling process of the bladder model 13: using the manual control device 23, physiological saline is continuously and constantly injected into the kidney model 11 through the syringe. After being collected by the renal calyces and renal pelvis of the kidney model 11, the physiological saline flows into the ureter model 12 and then into the bladder model 13. Since the screw adjustment valve at the end of the urethral model 14 is in the closed state (simulating the contraction of the urethral sphincter during urine storage), the liquid cannot be discharged, and the bladder model 13 begins to gradually fill and expand. During this filling process, the pressure sensor 131 fixed at the bottom of the bladder model 13 monitors and records the rising process of the intravesical pressure in real time.

[0034] Emptying process of the bladder model 13: when the bladder model 13 is filled to a preset volume or the pressure reaches a predetermined value (simulating the sensation of bladder filling), the screw adjustment valve at the end of the urethral model 14 is manually opened (simulating the relaxation of the urethral sphincter during urination). Under the action of the elastic retraction force of the bladder model 13 (simulating the contraction of the detrusor muscle) or the slight abdominal pressure (which can be simulated by manually pressing the bladder model 13), the liquid in the bladder model 13 begins to flow through the narrowed urethral model 14 compressed by the prostate model 15, and finally is discharged from the end of the urethral model 14. At this time, due to the high flow resistance of the narrowed urethra (provided by the prostate model 15), the urination flow rate decreases and the urination time extends. The pressure sensor 131 continuously monitors and records the dynamic pressure change curve of the bladder model 13 during the entire emptying process, which clearly reflects the characteristics of urinary obstruction caused by prostate compression, such as increased intravesical pressure during urination, prolonged urination time, and reduced urine flow rate.

[0035] Finally, the computer terminal 33 collects the data of the pressure sensor 131 during the entire filling period (pressure rise) and emptying period (pressure change and decline) through the data acquisition card, forming a complete "urine storage-urination" cycle bladder pressure-time curve, which is used to analyze the effect of prostate compression on lower urinary tract function.

[0036] Close the screw adjustment valve at the end of the urethral model 14 (ensure the outlet is sealed), open the air pump 22 to inject gas into the sealed cavity of the prostate model 15, and the gas quickly fills the sealed cavity of the prostate model 15. Because the gas is incompressible and the silicone wall of the cavity is uniform in thickness, the sealed cavity is quickly rigidized, generating high-strength circumferential compression on the urethral model 14 passing through it. The urethral model 14 is extremely reduced in diameter under compression, even approaching closure (simulating mechanical obstruction of the urethra caused by prostate fibrosis or calcification). At the same time, the kidneys model 11 is continuously inputting simulated urine, and the liquid continuously flows into the closed bladder model 13, causing its volume to increase, and the intracavity liquid pressure begins to rise linearly; when the intravesical pressure rises to the minimum opening pressure required to resist the compression of the prostate (i.e. when the liquid can seep out through the extremely narrow urethra), or when the input flow rate and the seepage flow rate reach a dynamic balance, the intravesical pressure of the bladder model 13 enters a stable plateau period, and the pressure value displayed by the pressure sensor 131 remains relatively constant. Recording this stable value can be used to evaluate the bladder compensation capacity under the current prostate compression strength. The bladder pressure at which the intravesical pressure of the bladder model 13 rises to a stable state is obtained through the above operation.

[0037] Replace the ureter model 12 with different inner wall sizes (such as high resistance type, low resistance type, etc.) and the prostate model 15 with different cavity sizes (compression enhancement type, compression reduction type, etc.), and perform different model combinations, while performing the above liquid delivery process and the prostate disease simulation process. Collect the bladder pressure change curves under different conditions to observe the effects of different prostate diseases on the urination function of different patients.

[0038] In this embodiment, the software interface of the computer terminal 33 can display the pressure waveform of the pressure sensor 131 in real time, and the software supports historical data playback and export functions. Users can adjust the parameters of the multi-mode urinary pressure simulation and control system 2 (such as water injection volume and air injection volume) to simulate the pressure changes in various urinary system diseases or physiological states, providing support for medical research and clinical training.

[0039] In particular, in this embodiment, the prostate model 15 can also be replaced by different geometric shapes (such as spherical, elliptical, or irregular hyperplasia shape) to simulate the compression effect of prostate hyperplasia, calcified nodules, and other pathological states on the urethra.

[0040] In summary, the embodiments of the present application provide a urinary pressure test simulation environment experimental system device, which can solve the defects of existing models that are difficult to reproduce complex urinary system flow fields and anatomical details, and significantly improve the data accuracy and clinical relevance of urinary pressure test simulation environment experiments.

[0041] Embodiment Two The embodiment of the application provides a kind of urinary pressure test simulation environment experimental system device, wherein the device of the embodiment is basically same with embodiment one, different in that the urinary pressure test simulation environment experimental system device of the embodiment is as follows: The mobile terminal is connected with the pressure sensor by wireless communication; in the embodiment, the wireless communication includes one of Bluetooth, Wifi and ZigBee, and the mobile terminal includes a computer, a tablet computer and a mobile phone.

[0042] It should be noted that, according to the needs of implementation, each step described in the application can be split into more steps, or two or more steps or part of the operation can be combined into a new step to achieve the purpose of the application.

[0043] Those skilled in the art readily understand that the above only describes the preferred embodiments of the application and is not intended to limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application shall be included in the protection scope of the application.
