[0002] Overactive bladder (OAB) is a syndrome characterized by urinary urgency, often accompanied by urinary frequency and nocturia, with or without urge incontinence. This condition can seriously affect patients' daily life and social activities, and may cause patients to experience negative emotions such as anxiety, embarrassment, frustration and even depression.

[0003] The clinical diagnosis of overactive bladder relies on urodynamic testing to obtain bladder pressure, which can be used to evaluate bladder function and pressure changes, understand the pressure levels of the bladder at rest and during filling, and thus assist doctors in diagnosis.

[0026] The embodiment of the present application provides a dynamic bladder pressure measurement device to solve the technical problems of poor measurement accuracy, inconvenient measurement and poor patient experience in the prior art urodynamic detection method.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] One or more embodiments of the present application provide a dynamic cystometry device for dynamically monitoring bladder pressure changes over a long period of time (eg, 24 hours).

[0029] like Figure 1 ,2 As shown, the device described in the embodiment of the present application includes:

[0030] A pressure measuring tube 20, wherein the front end of the pressure measuring tube 20 is used to extend into the bladder, and the rear end of the pressure measuring tube 20 is connected to a manometer 30, and the manometer 30 is used to measure the real-time pressure of the bladder;

[0031] A urinary tube 40, the front end of which is used to extend into the bladder, and the rear end of which is connected to a urine collecting device 90;

[0032] A pressure control valve 50, wherein the pressure control valve 50 is disposed on the urine discharge tube 40 to control the opening and closing of the urine discharge tube 40;

[0033] A controller 100, wherein a signal input end of the controller 100 is connected to the pressure meter 30, and is used to receive a real-time pressure signal acquired by the pressure meter 30. A signal output end of the controller 100 is connected to the pressure control valve 50, and the signal output end of the controller 100 outputs a control signal, and the control signal is used to control the opening or closing of the pressure control valve 50, thereby allowing the bladder to urinate or store urine.

[0034] Specifically, the controller 100 pre-stores a valve opening pressure value (e.g., 10-15 cm H2O) and a valve closing pressure value (e.g., 5 cmH2O). After receiving the real-time pressure signal, the controller 100 compares the real-time pressure with the valve opening pressure value and the valve closing pressure value, respectively, and generates the control signal according to the comparison result, as follows: when the real-time pressure is higher than the valve opening pressure value, the controller 100 controls the pressure control valve 50 to open, and the urine in the bladder can be discharged into the urine collecting device 90 through the urination tube 40; when the real-time pressure is lower than the valve closing pressure value, the controller 100 controls the pressure control valve 50 to close, the urination tube 40 no longer discharges urine, and the bladder begins to store urine until the next time the real-time pressure is higher than the valve opening pressure value, and the pressure control valve 50 is reopened, and the cycle continues.

[0035] From the above description, it can be known that the dynamic bladder pressure measuring device described in the embodiment of the present application measures the real-time pressure of the bladder by setting the pressure measuring tube 20 and the pressure measuring device 30, and controls the urination or storage of the bladder by setting the urination tube 40, the pressure control valve 50 and the controller 100, and can automatically urinate according to the bladder pressure, so that the patient can urinate during the measurement period, and can perform measurements for a longer time, such as 24-hour dynamic monitoring of bladder pressure changes, so as to obtain more comprehensive and true bladder pressure data, and the patient can use it at home, which is particularly suitable for use during surgery; at the same time, the dynamic bladder pressure measuring device described in the embodiment of the present application does not need to be used to infuse physiological saline into the bladder, is convenient and easy to use, and has a good user experience for patients, which effectively solves the technical problems of poor measurement accuracy, inconvenient measurement and poor patient experience in the urodynamic detection method in the prior art.

[0036] It should be noted that the principle and implementation method of the controller 100 controlling the opening or closing of the pressure control valve 50 can be obtained based on the existing technology and do not belong to the scope of protection of the embodiments of the present application, and will not be described here.

[0037] In addition, the pressure measuring device 30 and the pressure control valve 50 can both be mature products on the market.

[0038] In one embodiment of the present application, the device further comprises a tube body 10, and the tube body 10 is fixed in the body by a fixing assembly, so as to be retained in the body.

[0039] Furthermore, the pressure measuring tube 20 and the urination tube 40 are both passed through and fixedly arranged in the tube body 10 , so that the pressure measuring tube 20 and the urination tube 40 can be stably placed in the human body for measurement and urination because of the fixation of the tube body 10 .

[0040] In one embodiment of the present application, the fixing assembly includes an airbag 70, and the airbag 70 is connected to an injection tube 60 for injecting a filling medium into the airbag 70. The airbag 70 expands after the filling medium is injected through the injection tube 60, and contracts after the filling medium is discharged through the injection tube 60; and the injection tube 60 is fixedly connected to the tube body 10.

[0041] Specifically, the airbag 70 is inserted into the urethra when it is in an empty state, and then expanded by injecting a filling medium through the injection tube 60 until the airbag 70 is stuck in the urethra and does not fall off, thereby achieving the fixation of the tube body 10 in the human body.

[0042] In one embodiment of the present application, the injection tube 60 passes through the tube body 10 , and the front end of the injection tube 60 is connected to the airbag 70 , and the rear end of the injection tube 60 is reserved with an injection port 61 .

[0043] Specifically, the injection port 61 is exposed at the rear end of the tube body 10 to facilitate the injection of the filling medium during use, which is convenient and easy to use.

[0044] In one embodiment of the present application, the filling medium is sterile water, which is not only easily available but also harmless.

[0045] In one embodiment of the present application, the device further comprises a metering unit 80, which is used to measure a single urine volume, and the metering unit 80 is connected between the urine collection bag and the pressure control valve 50;

[0046] The metering part 80 is connected to the controller 100, and the controller 100 controls the metering part 80 to be opened or closed, so as to start measuring the single urine volume when the pressure control valve 50 is opened, and end measuring the single urine volume when the pressure control valve 50 is closed, thereby obtaining the single urine volume introduced into the urine collecting bag by the urination tube 40 between each opening and closing of the pressure control valve 50.

[0047] Specifically, after the pressure control valve 50 is opened, the controller 100 synchronously drives the metering unit 80 to start measuring the cumulative urine volume passing through the urinary tube 40 until the pressure control valve 50 is closed, and the controller 100 synchronously drives the metering unit 80 to end the metering, thereby obtaining the single urine volume, further enriching the bladder pressure data, making it easier for doctors to evaluate the bladder function and pressure changes, and assisting doctors in making accurate diagnoses.

[0048] In one embodiment of the present application, the measuring unit 80 also includes a first recording unit, which is used to record the single urine volume obtained by the measuring unit 80, and the first recording unit is connected to the controller 100. The controller 100 receives and stores the single urine volume recorded by the first recording unit, and accumulates the single urine volume to obtain the total urine volume for the doctor to view.

[0049] In one embodiment of the present application, the metering unit 80 also includes a second recording unit, which is used to record the cumulative number of times the pressure control valve 50 is opened and / or closed, and the second recording unit is connected to the controller 100.

It can be seen that the types of data obtained are many and the data volume is large, which is conducive to the doctor's comprehensive review and diagnosis.

[0052] In one embodiment of the present application, the urine collecting device 90 is a urine collecting bag.

[0053] An exemplary method of using a dynamic cystometry device provided in an embodiment of the present application is as follows:

[0054] The medical staff indwells the dynamic cystometry device described in the embodiment of the present application, injects 10 ml of water into the airbag 70, sets the valve opening pressure value and valve closing pressure value of the pressure control valve 50 (for example, the valve opening pressure value can be 10-15 cm H2O, and the valve closing pressure value can be 5 cm H2O), and the patient can leave the hospital and go home for monitoring;

[0055] The pressure measuring tube 10 and the pressure measuring device 30 measure the real-time pressure of the bladder. When the real-time pressure in the bladder is higher than the set valve opening pressure value, the pressure control valve 50 opens, and urine flows out through the urinary tube 40. The measuring unit starts to measure the single urine volume, the second recording unit records the cumulative number of times the control valve 50 is opened, and the third recording unit records the time when the pressure control valve 50 is opened.

[0056] When the real-time pressure in the bladder is lower than the set valve closing pressure value, the pressure control valve 50 is closed, and the single urine volume measurement ends. The first recording unit records the single urine volume, the second recording unit records the cumulative number of times the control valve 50 is closed, and the third recording unit records the time when the pressure control valve 50 is closed. The controller calculates the current total urine volume.
