Description

Technical Field

[0001] This invention relates to the field of bladder rehabilitation technology, and in particular to a urinary catheter bag assembly. Background Technology

[0002] Using clamping devices for bladder training is an important technique in bladder rehabilitation. Clamping devices primarily control the free flow of urine through a urine bag and the clamping device itself, stimulating the bladder's feeling of fullness and peristaltic movement. This strengthens bladder muscles and, by adapting to a certain urine volume and appropriate peristaltic rhythm, gradually restores normal urinary control and bladder function. However, when using clamping devices to prevent urine flow, it is crucial to pay attention to the timing of removal. Prolonged restriction of urine flow can harm the bladder, leading to conditions such as bladder distension, impaired bladder muscle function, bladder infection, or stone formation.

[0003] Currently, the timing for removing the clamping device is mainly determined by setting a timer. However, since the bladder filling speed and urination interval are affected by many factors such as drinking water, diet, sweating, environment and habits, patients with different diseases and receiving different treatments have different urine production speeds and urine volumes. Accordingly, the bladder training time required by different patients is different.

[0004] If the timing for removing the clamping device is determined by setting a timer, there is a problem of inaccurate timing. For example, if the timer is set to remove the clamp after 40 minutes, and patient A requires 60 minutes of bladder training while patient B requires 30 minutes, when the timer ends, patient A may not have reached the required training time and the clamp should be removed, while patient B may have reached the required training time but the clamp was not removed in time because the timer has not ended, resulting in bladder damage. Therefore, simply using the clamping time to determine the timing for removal is inaccurate and not well-suited for different bladder training populations. Thus, designing a catheter bag that can accurately monitor the progress of bladder training is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that using the clamping time to determine the timing for removing the clamping device to end bladder training is inaccurate. This invention provides a catheter bag assembly that can accurately determine the timing for removing the clamping device to end bladder training.

[0006] To address the aforementioned technical problems, embodiments of the present invention disclose a urinary catheter assembly, comprising: a urine collection bag for collecting patient urine; a urinary catheter, one end of which is connected to the patient's bladder, and the other end of which is connected to the urine collection bag; a first pressure sensor disposed on the inner wall of the urinary catheter; a clamping device for clamping the urinary catheter to place it in a closed state, the clamping position of the clamping device being located between the first pressure sensor and the urine collection bag, the first pressure sensor being used to detect the urine pressure within the urinary catheter in the closed state; and a prompting device connected to the first pressure sensor, the prompting device being able to receive a pressure signal corresponding to the urine pressure transmitted by the first pressure sensor, and prompting the user to remove the clamping device based on the pressure signal.

[0007] Using the above technical solution, this application uses a clamping device to clamp the urinary catheter, keeping it in a closed state to allow the patient to perform bladder exercises. At this time, the urinary catheter and bladder form a closed space. The urine pressure sensed by the first pressure sensor reflects the urine pressure inside the bladder. A prompting device is provided to receive the pressure signal transmitted by the first pressure sensor, so that the prompting device operates according to the pressure signal sensed by the first pressure sensor. At this time, the pressure signal can provide real-time feedback on the pressure value of the urine accumulated inside the bladder due to bladder exercises. When this pressure value reaches a set value, the patient or medical staff can remove the clamping device according to the working status of the prompting device. Compared with the prior art, which can only use a timer device to generally determine when to remove the clamping device, the timing of removing the clamping device in this application (i.e., the prompting time of the prompting device) corresponds to the real-time urine volume in the bladder. Therefore, this application can greatly improve the accuracy of judgment by monitoring the urine pressure inside the bladder to determine when to remove the clamping device.

[0008] Furthermore, it can be applied to different bladder training groups. For example, different pressure settings can be set according to different bladder training groups. Not all bladder training groups need to be prompted to remove the clamping device under the same pressure setting, which improves the user experience of bladder training.

[0009] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urinary catheterization bag assembly, wherein the prompting device includes a display, the display being disposed on the urinary collection bag, and a first pressure sensor being connected to the display to enable the display to show a bladder exercise progress value, the bladder exercise progress value being positively correlated with the amount of urine in the bladder.

[0010] Using the above technical solution, this application uses a first pressure sensor to sense the urine pressure inside the closed catheter in real time and converts it into an electrical signal, which is then output to a display. The display shows the progress of bladder training. When the clamping device closes the catheter, creating a closed space between the catheter and the bladder, the urine pressure sensed by the first pressure sensor reflects the pressure inside the bladder, thus indicating the progress of bladder training. In other words, urine pressure and bladder training progress are positively correlated, meaning the displayed bladder training progress value is positively correlated with the amount of urine in the bladder. This allows the patient or caregiver to easily observe the display to understand the progress of bladder training and determine when to remove the clamping device.

[0011] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urinary catheter assembly, which further includes a second pressure sensor and a counter. The second sensor is disposed on the inner wall of the urinary catheter and is located between the clamping position of the clamping device and the urine collection bag. The clamping device is capable of releasing the urinary catheter to make the urinary catheter in a conductive state. The second pressure sensor is used to detect the urine pressure in the urinary catheter in the conductive state. The counter is disposed on the urine collection bag. When the second pressure sensor detects pressure, the counter counts and displays the number of times the clamping device is opened.

[0012] Using the above technical solution, the second pressure sensor is placed between the clamping position of the clamping device and the urine collection bag. When the patient or their caregiver loosens the clamping device to open the catheter, urine flows from the clamping position through the second pressure sensor into the urine collection bag. The second pressure sensor can detect the urine pressure to provide feedback on the number of times the clamping device has been loosened. Each loosening of the clamping device indicates the completion of one bladder exercise. At this time, the second pressure sensor transmits the pressure signal to the counter. The counter records the number of bladder exercises based on the pressure signal, which allows doctors to easily observe the number of bladder exercises and rationally arrange the course of bladder exercise treatment.

[0013] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urine collection bag assembly. The prompting device further includes a controller and an alarm device. The controller and the alarm device are disposed on the urine collection bag. The controller is connected to the first pressure sensor, and the alarm device is connected to the controller. When the pressure detected by the first pressure sensor reaches a set value, the controller controls the alarm device to sound an alarm.

[0014] Using the above technical solution, the first pressure sensor detects the urine pressure in the closed catheter and converts it into an electrical signal output to the display. When the pressure detected by the first pressure sensor reaches the set value, the first pressure sensor transmits an electrical signal to the controller. The controller receives the signal and transmits an electrical signal to the alarm device, which then sounds an alarm to remind the patient's family or caregivers to remove the clamping device, thereby preventing the patient or their family from forgetting to remove the clamping device and causing harm to the bladder.

[0015] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urinary catheterization bag assembly, wherein the display is capable of displaying the bladder exercise progress value in the form of a progress bar.

[0016] Using the above technical solution, the progress of bladder training can be observed by looking at the scale on the monitor, making it convenient for patients or their families to observe the progress of bladder training in real time.

[0017] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urine collection bag assembly, wherein the urine collection bag includes a panel disposed at the upper end of the urine collection bag, and the display, the controller, the counter and the alarm device are all disposed on the panel.

[0018] By adopting the above technical solution, the display, controller, counter and alarm device are integrated on the panel, which makes it convenient for patients or their families to centrally observe the progress and number of bladder exercises.

[0019] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urinary catheter bag assembly, wherein the controller is wirelessly connected to the first pressure sensor.

[0020] By adopting the above technical solution, the controller is wirelessly connected to the first pressure sensor, avoiding tangled wiring in the catheter bag and simplifying its structure.

[0021] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urinary catheterization bag assembly, wherein the alarm device includes an alarm indicator light, a buzzer, or a voice prompt.

[0022] Using the above technical solution, the alarm indicator light or buzzer can remind the patient's family or caregivers to remove the clamping device in time through light or sound sources, so as to avoid damage to the patient's bladder.

[0023] According to another specific embodiment of the present invention, an embodiment of the present invention discloses a urine collection bag assembly, wherein the urine collection bag further includes a discharge port for discharging urine from inside the urine collection bag.

[0024] By adopting the above technical solution, after the urine collection bag is full, the discharge port can be opened to allow the urine inside the urine collection bag to be discharged from the discharge port, thus realizing the recycling of the urine collection bag.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0036] refer to Figure 1 This application provides a urine collection bag assembly, including: a urine collection bag 10, a urine catheter 20, a clamping device 30, a first pressure sensor 21, and a prompting device 40.

[0037] The urine collection bag 10 is used to collect and store the patient's urine; one end of the catheter 20 is connected to the patient's bladder, and the other end of the catheter 20 is connected to the urine collection bag 10. Exemplarily, the catheter 20 is made of a soft material. A first pressure sensor 21 is located on the inner wall of the catheter 20 and does not obstruct the normal flow of urine within the catheter 20.

[0038] The clamping device 30 is used to clamp the urinary catheter 20 to keep the urinary catheter 20 in a closed state, and to release the urinary catheter 20 to keep the urinary catheter 20 in a conductive state. The clamping position of the clamping device 30 is located between the first pressure sensor 21 and the urine collection bag 10. The first pressure sensor 21 is used to detect the urine pressure in the urinary catheter 20 when it is in a closed state.

[0039] The prompting device 40 is connected to the first pressure sensor 21. For example, the prompting device 40 is connected to the first pressure sensor 21 via a signal (communication signal or electrical signal). The prompting device 40 can receive the pressure signal corresponding to the urine pressure transmitted by the first pressure sensor 21 and prompt the user to remove the clamping device 30 according to the pressure signal. After the user removes the clamping device 30, the bladder exercise can be ended.

[0040] Using the technical solution of this application, the urinary catheter 20 is clamped by the clamping device 30 to keep the urinary catheter 20 in a closed state so that the patient can perform bladder exercises. At this time, the urinary catheter 20 and the bladder form a closed space. The urine pressure sensed by the first pressure sensor 21 can reflect the urine pressure inside the bladder. A prompting device 40 is provided to receive the pressure signal transmitted by the first pressure sensor 21 so that the prompting device 40 works according to the pressure signal sensed by the first pressure sensor 21.

[0041] At this time, the pressure signal can provide real-time feedback on the pressure value of the urine accumulated inside the bladder due to bladder exercise. When the pressure value reaches the prompting set value of the prompting device 40, it indicates that the bladder exercise is complete. The patient or medical staff can then remove the clamping device 30 according to the working status of the prompting device 40. Compared with the prior art, which can only generally determine the timing of removing the clamping device by setting a timer, the timing of removing the clamping device 30 in this embodiment (i.e., the indication of the prompting device 40) corresponds to the real-time urine volume in the bladder. Therefore, the accuracy of this embodiment in determining the timing of removing the clamping device 30 by monitoring the pressure of urine inside the bladder can be greatly improved.

[0042] Specifically, refer to Figure 1 The urine collection bag 10 is used to collect and store patient urine. The urine collection bag 10 has an inlet 11 at the top and an outlet 12 at the bottom. The urine collection bag 10 is connected to the catheter 20 through the inlet 11, and the outlet 12 is used to discharge the urine inside the urine collection bag 10. The urine collection bag 10 is typically a sealable bag-shaped container. Exemplarily, in this embodiment, the urine collection bag 10 is a reusable sealable bag-shaped container. However, this embodiment does not limit the type of urine collection bag 10. The type of urine collection bag 10 is not limited to a reusable sealable bag-shaped container; for example, in some possible implementations, the urine collection bag 10 may be a disposable sealable bag-shaped container.

[0043] Furthermore, the outer surface of the urine collection bag 10 is marked with graduations to reflect the amount of urine collected. For example, the graduation range of the urine collection bag 10 in this embodiment is 0 to 1500 ml (inclusive). This embodiment does not limit the graduation range of the urine collection bag 10; for example, in some possible implementations, the graduation range of the urine collection bag 10 is 0 to 2000 ml (inclusive).

[0044] Continue to refer to Figure 1The urinary catheter 20 is a tube used to drain urine. A urinary catheter is placed in the patient's bladder in advance. One end of the urinary catheter 20 is connected to the urinary catheter to drain the urine in the patient's bladder, and the other end is connected to the urine collection bag 10 through the inlet 11. The urinary catheter 20 is used to drain the patient's urine into the urine collection bag 10. It is mainly used when the patient is unable to urinate on his own or when it is necessary to monitor the urine flow.

[0045] For example, in order to facilitate observation of urine flow, the urinary catheter 20 in this embodiment of the application is a transparent tube made of polyurethane. However, this embodiment of the application does not limit the material and transparency of the urinary catheter 20. For example, in some possible implementations, the urinary catheter 20 may be made of opaque silicone tube.

[0046] Furthermore, the diameter of the catheter 20 is generally expressed in "French" units, with French units typically converting to millimeters (mm) as approximately 1 French unit equals 0.33 millimeters. Exemplarily, this application embodiment uses a catheter 20 with a diameter ranging from 18 French to 22 French (inclusive), that is, a catheter 20 with a diameter between 5.94 mm and 7.26 mm (inclusive). However, this application embodiment does not limit the diameter of the catheter 20; for example, in some possible implementations, the diameter of the catheter 20 can be between 6 French and 17 French (inclusive), that is, between 1.98 mm and 5.61 mm (inclusive).

[0047] Continue to refer to Figure 1 The first pressure sensor 21 is disposed on the inner wall of the catheter 20. Specifically, the first pressure sensor 21 is embedded in the inner wall of the catheter 20. When urine flows in the catheter 20, the first pressure sensor 21 can detect the pressure of the urine inside the catheter 20. This application does not limit the way the first pressure sensor 21 is disposed on the inner wall of the catheter 20. For example, in some possible embodiments, the first pressure sensor 21 is attached to the inner wall of the catheter 20 to detect the pressure of the urine inside the catheter 20.

[0048] Continue to refer to Figure 1 When the catheter 20 is closed, the patient's urine cannot be discharged into the urine collection bag 10 through the catheter 20, thus stimulating the bladder's feeling of fullness and peristalsis, thereby achieving the effect of bladder training. When the catheter 20 is released to allow it to be open, urine can be discharged freely, at which point the bladder training ends.

[0049] The clamping device 30 is positioned between the first pressure sensor 21 and the urine collection bag 10. At this point, the clamping section A of the catheter 20 forms a closed space with the bladder, and the urine pressure sensed by the first pressure sensor 21 reflects the pressure inside the bladder. As urine fills, it accumulates in the bladder and clamping section A, increasing the pressure detected by the first pressure sensor 21. Therefore, the pressure detected by the first pressure sensor 21 can reflect the pressure inside the bladder in real time.

[0050] refer to Figure 1 and combined Figure 2 In some possible implementations, the prompting device 40 includes a display 41 disposed on the urine collection bag 10. The first pressure sensor 21 is connected to the display 41 so that the display 41 can display the bladder exercise progress value. Specifically, when the clamping device 30 clamps the catheter 20, since the catheter 20 and the bladder form a closed space, the urine pressure sensed by the first pressure sensor 21 can reflect the pressure inside the bladder.

[0051] The working principle of a pressure sensor is to measure the pressure applied to the sensor by the measured medium and convert it into an electrical signal proportional to the pressure. Specifically, in this embodiment, the first pressure sensor 21 is signal-connected to the display 41. The first pressure sensor 21 measures the pressure applied to it by urine and converts it into an electrical signal proportional to the pressure, which is then output to the display 41. Thus, the display 41 can proportionally display the pressure detected by the first pressure sensor 21.

[0052] After clamping the urinary catheter 20, the patient begins bladder exercises. Urine fills and accumulates in the bladder and clamped area A. During bladder exercises, the pressure detected by the first pressure sensor 21 increases as urine fills, and the display 41 also reflects the increasing pressure inside the bladder detected by the first pressure sensor 21. When the display 41 reaches the effective bladder exercise progress value, the clamping device 30 is removed, urine is allowed to drain freely, and the bladder exercises end.

[0053] Therefore, since the first pressure sensor 21 can convert the detected bladder internal pressure into an electrical signal and output it to the display 41 in real time, the magnitude of the bladder internal pressure is positively correlated with the progress value of bladder exercise, and the progress value of bladder exercise is positively correlated with the amount of urine in the bladder. It should be noted that this positive correlation includes linear or nonlinear relationships; as long as it reflects the trend of bladder exercise progress increasing with the increase of urine volume, it falls under the positive correlation referred to in the embodiments of this application.

[0054] refer to Figure 1 and combined Figure 2Since the first pressure sensor 21 can detect the urine pressure inside the closed catheter 20 in real time and convert it into an electrical signal output to the display 41, the first pressure sensor 21 can convert the detected bladder pressure into an electrical signal output to the display 41 in real time. The display 41 is equipped with a progress bar, which can display the bladder exercise progress value in the form of a progress bar. Figure 2 The display 41 is provided with progress values ​​from 0 to 100%.

[0055] For example, the bladder training process in this application embodiment is as follows: the user clamps the catheter 20 to start bladder training, and then urine accumulates in the bladder and clamped area A and applies increasing pressure to the first pressure sensor 21 until the accumulated urine volume reaches the effective bladder training standard (which can be determined according to the doctor's order). At this time, the user releases the catheter 20 and ends the bladder training.

[0056] The bladder training progress value refers to the progress value displayed on the display 41 during the above process, that is, the progress value displayed on the display 41 when the pressure signal transmitted by the first pressure sensor 21 is converted into an electrical signal received by the display 41. The effective bladder training progress value refers to the progress value displayed on the display 41 when the clamping device 30 is removed, that is, the value displayed on the display 41 when the accumulated urine volume reaches the urine volume of the effective bladder training standard, and the pressure signal transmitted by the first pressure sensor 21 is converted into an electrical signal received by the display 41.

[0057] For example, in this embodiment, the effective bladder training progress value is 100%, that is, when the value displayed on the monitor 41 is 100%, the patient has reached the standard for effective bladder training and can stop training. This embodiment does not limit the effective bladder training progress value. In some possible implementations, due to differences in bladder capacity and treatment duration among different patients, doctors may issue different medical orders to different patients. The effective bladder training progress value in these orders can be any progress value below 100%. For example, if the effective bladder training progress value is 70%, the patient can stop training once they reach this effective bladder training progress value (e.g., the effective bladder training progress value displayed on the monitor 41 is 70%). Alternatively, if the bladder training progress value is 80%, the patient can stop training once they reach this effective bladder training progress value (e.g., the effective bladder training progress value displayed on the monitor 41 is 80%).

[0058] The above-described configuration allows patients or their caregivers to determine the appropriate time to remove the clamping device 30 by observing the progress reading on the display 41. Therefore, the catheter bag assembly provided in this embodiment can be applied to different user groups, enabling appropriate bladder training based on the individual user's condition.

[0059] For example, in this embodiment of the application, when the accumulated urine volume in the bladder and clamped area A reaches 300ml, the standard for effective bladder training is met. At this time, the first pressure sensor 21 converts the pressure signal of 300ml of urine into an electrical signal and transmits it to the display 41. The progress displayed on the display 41 is the effective bladder training progress value. The patient can remove the clamping device 30, restore free urine drainage, and end the bladder training.

[0060] Furthermore, patients or caregivers can observe the progress bar on display 41 at any time to track the progress of bladder training. For example, if a user's effective bladder training progress value is 70%, and the display 41 shows 50%, the urine volume in the bladder is 150ml, indicating that the effective bladder training standard has not yet been met. Therefore, the clamping device 30 remains in the clamped state. The clamping device 30 is removed and the bladder training ends when the patient or caregiver observes that the display 41 still shows an effective bladder training progress value of 70%. Exemplarily, in this embodiment, the display 41 only displays the progress value, not the specific pressure value or bladder capacity value. Therefore, patients or their caregivers do not need to remember the cumbersome specific pressure or bladder capacity values; they only need to observe the progress on display 41, making it easier for illiterate patients or their families to understand and track the progress of bladder training.

[0061] This application embodiment does not limit the amount of urine accumulated in the bladder and clamped zone A when the display 41 reaches the effective bladder training progress value. In some possible implementations, due to differences in bladder capacity among different patients, the amount of urine accumulated in the bladder and clamped zone A when the progress displayed on the display 41 is the effective bladder training progress value can be a value such as 100ml or 200ml. For example, if the urine volume displayed on the display 41 is 100ml, the patient has reached the standard for effective bladder training and can stop training. Or, if the urine volume displayed on the display 41 is 200ml, the patient has reached the standard for effective bladder training and can stop training. Similarly, this application embodiment does not limit the urine volume value corresponding to effective bladder training. In some possible implementations, due to differences in bladder capacity and treatment duration among different patients, doctors can issue different medical orders to different patients. The urine volume value corresponding to reaching the effective bladder training standard in the medical order can be a value such as 300ml, 400ml, 450ml, 500ml, etc.

[0062] refer to Figure 1 and combined Figure 5In some possible implementations, the urinary catheter bag assembly further includes a second pressure sensor 22 and a counter 131. The second pressure sensor 22 is disposed on the inner wall of the urinary catheter 20 and is located between the clamping position of the clamping device 30 and the inlet 11. The second pressure sensor 22 is used to detect the urine pressure in the urinary catheter 20 when it is in a conductive state. The counter 131 is disposed on the urine collection bag 10. When the second pressure sensor 22 detects pressure, the counter 131 counts and displays the number of times the clamping device 30 is opened.

[0063] For example, when the clamping device 30 is removed, the urinary catheter 20 resumes the flow of urine. The second pressure sensor 22 can detect the pressure signal generated by the urine flowing through the second pressure sensor 22 after the urinary catheter 20 resumes the flow. The second pressure sensor 22 transmits the pressure signal to the counter 131. The counter 131 records the number of times the clamping device 30 is opened as 01, which means that the patient has completed one bladder exercise.

[0064] Furthermore, when the next bladder exercise begins, no urine flows through the second pressure sensor 22 due to the clamping device 30, and the second pressure sensor 22 is not activated at this time. When the bladder exercise ends, the clamping device 30 is removed, urine flows through the second pressure sensor 22, and the second pressure sensor 22 transmits this pressure signal to the counter 131 for reference. Figure 1 and Figure 3 , Figure 1 and Figure 3 The counter 131 shows that the number of times the clamping device 30 was opened is 02, which means that the patient has completed two bladder exercises.

[0065] The above process uses a counter 131 to record the number of bladder exercises, allowing doctors to know the number of bladder exercises the patient has performed and to rationally plan the patient's bladder exercise course. It should be noted that this embodiment does not limit the number of times the clamping device can be opened; the display will reflect the number of bladder exercises performed by the user, for example, 03 (indicating three bladder exercises have been completed).

[0066] Continue to refer to Figure 1 and combined Figure 4 In some possible implementations, the prompting device 40 also includes a controller 42 and an alarm device 43, which are located on the urine collection bag 10. The controller 42 is connected to the first pressure sensor 21, and the alarm device 43 is connected to the controller 42.

[0067] When the pressure detected by the first pressure sensor 21 reaches the alarm set value, that is, when the amount of urine accumulated in the bladder and clamped zone A reaches the effective bladder training progress value, the first pressure sensor 21 transmits an electrical signal to the controller 42. After receiving the electrical signal, the controller 42 transmits a signal to the alarm device 43, and the alarm device 43 sounds an alarm, reminding the patient or caregiver to remove the clamping device 30, restore the free flow of urine, and complete the bladder training. This avoids the situation where the patient or their family forgets to remove the clamping device 30, which could cause harm to the bladder.

[0068] For example, in this embodiment of the application, when the pressure detected by the first pressure sensor 21 reaches 30N, that is, when the amount of urine accumulated in the bladder and the clamped area A reaches 300ml, the first pressure sensor 21 transmits an electrical signal to the controller 42. After receiving the electrical signal, the controller 42 controls the alarm device 43 to sound an alarm, reminding the patient or caregiver to remove the clamping device 30 and complete the bladder exercise, thereby avoiding the situation where the patient or their family members forget to remove the clamping device 30, which may cause harm to the bladder.

[0069] In some possible implementations, due to differences in bladder capacity and treatment duration among different patients, different bladder capacities correspond to different pressure values. The alarm setting value of the first pressure sensor 21 can be set according to a user-defined value. For example, the controller 42 is provided with a button for inputting the alarm pressure setting value, and the user can set the alarm setting value of the first pressure sensor 21 by entering different alarm pressure setting values ​​in the controller 42.

[0070] For example, the user enters 20N into the controller 42 to customize the user's alarm pressure setting. When the pressure detected by the first pressure sensor 21 reaches 20N, the first pressure sensor 21 transmits an electrical signal to the controller 42. Upon receiving the electrical signal, the controller 42 activates the alarm device 43 to remind the patient or caregiver to remove the clamping device 30 and complete bladder exercises. This prevents the patient or their family from forgetting to remove the clamping device 30, which could harm the bladder.

[0071] Alternatively, in some possible implementations, the user enters 40N into the controller 42 to customize the user's alarm pressure setting. When the pressure detected by the first pressure sensor 21 reaches 40N, the first pressure sensor 21 transmits an electrical signal to the controller 42. Upon receiving the electrical signal, the controller 42 controls the alarm device 43 to sound an alarm, reminding the patient or caregiver to remove the clamping device 30 and complete bladder exercises.

[0072] The customizable alarm pressure setting makes the alarm device 43 more flexible in alerting patients. Compared with the factory-set alarm setting of the first pressure sensor 21, it can meet the bladder training needs of different patients.

[0073] For example, the alarm device 43 in this embodiment includes an alarm indicator light, a buzzer, or a voice prompt. When the pressure detected by the first pressure sensor reaches a set value, the first pressure sensor 21 transmits an electrical signal to the controller 42. After receiving the electrical signal, the controller 42 transmits a signal to the alarm device 43. The alarm device 43 flashes a warning light, emits a buzzer, or broadcasts a voice message such as "Please remove the clamping device" to remind the patient or caregiver to remove the clamping device 30, restore the free flow of urine, and complete bladder training.

[0074] Continue to refer to Figure 1 In some possible embodiments, the urine collection bag 10 also includes a panel 13, which is located at the upper end of the urine collection bag 10. The panel 13 is rectangular in shape and made of a rigid material, such as acrylic or plastic. The display 41, controller 42, counter 131, and alarm device 43 are all located on the panel 13. Integrating the display 41, controller 42, counter 131, and alarm device 43 on the panel 13 allows patients or their families to conveniently observe the progress and number of bladder exercises.

[0075] Continue to refer to Figure 1 and combined Figure 4 In some possible implementations, the controller 42 is wirelessly connected to the first pressure sensor 21. Both the controller 42 and the first pressure sensor 21 have built-in wireless modules, and the controller 42 and the first pressure sensor 21 are paired, enabling the controller 42 to recognize each other and establish a connection with the first pressure sensor 21 for data transmission.

[0076] Furthermore, the alarm device 43 is wirelessly connected to the controller 42. Both the alarm device 43 and the controller 42 have built-in wireless modules. The alarm device 43 and the controller 42 are paired, enabling the controller 42 to recognize and establish a connection with the alarm device 43 for data transmission. The display 41 is wirelessly connected to the first pressure sensor 21. The display 41 has a built-in wireless module, and the first pressure sensor 21 is paired with the display 41, enabling the first pressure sensor 21 to recognize and establish a connection with the display 41 to control the progress display on the display 41.

[0077] Furthermore, refer to Figure 1 and combined Figure 5 The counter 131 and the second pressure sensor 22 are wirelessly connected. Both the counter 131 and the second pressure sensor 22 have built-in wireless modules. The second pressure sensor 22 is paired with the counter 131 so that the second pressure sensor 22 can recognize each other and establish a connection with the counter 131 to control the counting of the counter 131.

[0078] refer to Figure 1 In some possible embodiments, the urine collection bag 10 also includes a discharge port 12, which is provided with a discharge valve 121. Controlling the discharge valve 121 to be in a closed state enables the urine collection bag 10 to collect urine, and controlling the discharge valve 121 to be in an open state enables the urine collection bag 10 to discharge urine.

[0079] Specifically, in this embodiment, when the patient's family member or caregiver removes the clamping device 30, urine flows into the urine collection bag 10 along with the catheter 20. At this time, the discharge valve 121 is closed, and the urine is collected inside the urine collection bag 10. When the urine collection bag 10 is full, the patient or caregiver opens the discharge valve 121 to open it, and the urine inside the urine collection bag 10 is discharged from the discharge port 12, thus realizing the recycling of the urine collection bag 10.

[0080] While the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the invention to these descriptions. Various changes in form and detail can be made by those skilled in the art, including several simple deductions or substitutions, without departing from the spirit and scope of the invention.
