Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, specifically to a neurogenic bladder urination alarm device. Background Technology

[0002] Neurogenic bladder is a common clinical syndrome characterized by impaired bladder voiding and / or storage function, resulting from damage to the body's normal urination reflex arc caused by various factors such as spinal cord injury, cerebrovascular accident, and diabetes. Because the nerve reflex arc of urination is damaged, patients cannot perceive the amount of urine in their bladder, thus requiring timed catheterization or bladder stimulation to empty the bladder. This mechanical, timed method of emptying the bladder makes it difficult for medical staff to monitor the urodynamics and volume of urine, affecting the effectiveness of treatment. Therefore, it is necessary to design a urination alarm device for neurogenic bladder.

[0003] To address the aforementioned technical problems, patent document CN210277188U discloses a neurogenic bladder emptying alarm device. Before use, a partition divides the interior of the casing into upper and lower cavities. Medical personnel first connect the drain tube to an existing external storage device. During use, the medical personnel insert the urinary catheter into the patient's bladder through the urethra, then manually close the first air valve. When the medical personnel need to empty the patient's bladder, they manually open the first air valve, allowing urine to drain through the catheter and connecting tube into the upper cavity of the casing. Simultaneously, a flow rate sensor monitors the flow rate of urine in the connecting tube and transmits the monitored value to a display. This monitoring of urine flow rate provides feedback on the patient's current bladder urodynamic state. Furthermore, when the patient... After urination, if the level sensor does not detect urine, the alarm will not activate, indicating that the patient's current urine output is below the required range. If the level sensor detects urine, it means the patient's current urine output has reached the required range, and the alarm will sound simultaneously. The alarm will alert the patient and medical staff that the urine output has reached the target. Medical staff can monitor the flow rate of the urine to understand the urodynamic status of the patient's bladder, allowing for appropriate rehabilitation treatment. After urination is complete, medical staff can manually open the solenoid valve to allow urine from the upper part of the housing to flow through the placement tube into the lower part of the housing 1. The medical staff then manually closes the first valve and continues to use the device to monitor the patient's urodynamics and urine output for the next time. This patented technical solution uses a level sensor to detect the amount of urine in the cavity of the partition, but it can only detect whether the urine volume reaches the required range; it cannot accurately detect the total amount of urine expelled. It is inconvenient to accurately monitor the patient's urine output and use urine output to reflect the patient's recovery status.

[0004] Patent document CN215017362U discloses a neurogenic bladder emptying alarm device. When using this device, a catheter is first inserted into the patient's bladder. When urine is produced, it is introduced into the housing through the catheter, causing the urine to accumulate above the piston and press down on it. An air bladder transmits the force of the piston to a pressure sensor. When the pressure reaches a preset range, a signal is transmitted to an alarm to sound, alerting the patient and medical staff that the current urine volume has reached the target. At this point, bladder function can be monitored. Simultaneously, a signal is transmitted to a telescopic motor to extend and retract. Through the rotating connection between the cover and the housing, and the design of the through-hole and collection tank, the urine at the top of the piston is guided into the collection tank through the through-hole by the support rod and pull rod, thereby improving drainage efficiency and convenience, and increasing the efficiency of secondary detection. This technical solution can accurately detect the urine excreted by the patient through a pressure sensor. However, prolonged contact between urine and the piston can easily corrode the piston's sealing ring, and impurities in the urine can easily adhere to the inside of the housing. During the patient's urination, the piston may not be able to move down effectively, leading to inaccurate urine test results. Utility Model Content

[0005] The main objective of this invention is to provide a neurogenic bladder emptying alarm device that can ensure the accuracy of patient urine test results and reflect the patient's recovery level based on the amount of urine discharged.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A neurogenic bladder emptying alarm device includes a housing, a pressure sensor fixed to the lower end of the housing, an inner housing fixed to the upper end of the pressure sensor, the inner housing being located inside the housing, a gap being provided between the outer edge of the inner housing and the inner edge of the housing, a drain pipe fixedly connected to the lower end of the inner housing, the lower end of the drain pipe penetrating a lower hole at the lower end of the housing, a solenoid valve being installed on the drain pipe, the diameter of the lower hole being larger than the outer diameter of the drain pipe, an inlet pipe fixed to the upper end of the housing, an upper hole concentric with the inlet pipe being opened at the upper end of the inner housing, the diameter of the upper hole being larger than the outer diameter of the inlet pipe, the lower end of the inlet pipe penetrating the upper hole, multiple one-way venting components being provided on the side wall of the housing, the upper end of the inlet pipe being fixedly connected to a urinary catheter, a valve being installed on the urinary catheter, a flow sensor being installed on the inlet pipe, an alarm being installed on the housing, a battery being electrically connected to a controller, a pressure sensor, a display, a flow sensor, an alarm, and a solenoid valve via wires, and the display, controller, flow sensor, pressure sensor, and alarm being communicatively connected via signal lines.

[0008] Specifically, the inlet pipe is a rigid transparent plastic pipe.

[0009] Specifically, the flow sensor is a clamp-type flow sensor.

[0010] Specifically, the one-way exhaust assembly includes a side hole opened on the side wall of the outer shell, an inner rod fixed inside the side hole, a connecting rod fixed on the inner rod, and a soft rubber cover fixed to the end of the connecting rod away from the inner rod. The soft rubber cover is located on the outside of the outer shell and seals the side hole.

[0011] Specifically, a vertical support rod is fixed to the upper end of the outer shell, an arc-shaped tube is fixed to the upper end of the support rod, a vertical smooth rod is fixed to the upper end of the outer shell on one side of the support rod, a pressure column is slidably sleeved on the smooth rod, a locking screw is threaded onto the pressure column, the locking screw is tightly abutted against the outer edge of the smooth rod, and the free end of the catheter passes through the arc-shaped tube and goes around the lower end of the pressure column before going upward.

[0012] Specifically, the optical rod is a square rod.

[0013] Specifically, the controller is a PLC controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. By setting up a flow sensor, when urine flows through the inlet tube, the flow sensor can detect the flow rate of urine in the inlet tube and transmit the monitored value to the display. By monitoring the urine flow rate, feedback can be provided on the patient's current urodynamic status of the bladder.

[0016] 2. Urine discharged from the inlet tube enters the inner shell. After the patient finishes urinating, the pressure sensor detects the weight of the inner shell and transmits this value to the display and controller. The controller has a preset normal urine volume value. The weight value transmitted to the controller is compared with this preset value. When the weight value is greater than or equal to the preset value, the patient's urine volume meets the standard, and the controller activates the alarm. Otherwise, the alarm does not sound. The alarm alerts the patient and medical staff that the current urine volume has met the standard. Simultaneously, the display shows the urine flow rate and weight values, facilitating monitoring by medical staff and the patient.

[0017] 3. By incorporating a one-way venting assembly, after urine enters the inner shell, the gas inside both the inner and outer shells can be released by pushing open the soft rubber cover, preventing pressure buildup within the inner and outer shells from affecting the flow rate of urine in the inlet tube. Simultaneously, when the patient is not urinating, this design prevents gas from escaping from the inner and outer shells and polluting the environment.

[0018] 4. By adjusting the position of the pressure column on the smooth rod, the movable length of the catheter can be adjusted, which can prevent the catheter from becoming too long and getting tangled.

[0019] 5. The patient's urine enters the inner shell for storage. The pressure sensor accurately detects the weight of the inner shell after the patient urinates, and this weight represents the amount of urine excreted. This allows for an accurate reflection of the patient's recovery progress based on the volume of urine produced. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1: Refer to Figures 1-2 As shown, a neurogenic bladder emptying alarm device includes a housing 1, a pressure sensor 13 fixed at the lower end of the housing 1, an inner housing 14 fixed at the upper end of the pressure sensor 13, the inner housing 14 being located inside the housing 1, and a gap being provided between the outer edge of the inner housing 14 and the inner edge of the housing 1.

[0026] The lower end of the inner shell 14 is fixedly connected to a pipe 2. The lower end of the pipe 2 passes through the lower hole 16 at the lower end of the outer shell 1. A solenoid valve 3 is installed on the pipe 2. The diameter of the lower hole 16 is larger than the outer diameter of the pipe 2.

[0027] The upper end of the outer shell 1 is fixed with an inlet pipe 5, and the upper end of the inner shell 14 is provided with an upper hole 15 concentric with the inlet pipe 5. The diameter of the upper hole 15 is larger than the outer diameter of the inlet pipe 5, and the lower end of the inlet pipe 5 passes through the upper hole 15.

[0028] The inlet tube 5 is a rigid transparent plastic tube. The upper end of the inlet tube 5 is fixedly connected to the urinary catheter 7, and a valve 20 is installed on the urinary catheter 7. A flow sensor 6 is installed on the inlet tube 5, and the flow sensor 6 is a clamp-type flow sensor.

[0029] An alarm is installed on the outer casing 1.

[0030] The battery is electrically connected to the controller, pressure sensor 13, display, flow sensor 6, alarm, and solenoid valve 3 via wires. The battery powers the controller, pressure sensor 13, display, flow sensor 6, alarm, and solenoid valve 3.

[0031] The display, controller, flow sensor 6, pressure sensor 13, and alarm are connected via signal lines. The controller is a PLC controller.

[0032] The flow sensor 6 can detect the flow rate of urine in the inlet tube 5 in real time and transmit the urine flow rate value to the display. After the patient finishes urinating, the pressure sensor 13 can detect the weight value of the inner shell 14. The weight value of the inner shell 14 is the value of the patient's urine output. The pressure sensor 13 can transmit the value of the patient's urine output to the display.

[0033] The free end of the catheter 7 passes through the patient's urethra and enters the patient's bladder. During urination, the valve 20 on the catheter 7 is opened, and the patient's urine enters the inner shell 14 through the catheter 7 and the inlet tube 5.

[0034] After the patient finishes urinating, pressure sensor 13 detects the amount of urine and transmits this value to the display and controller. The controller has a preset normal urine volume value. The transmitted urine volume value is compared with this preset value. If the transmitted value is greater than or equal to the preset value, the patient's urine volume meets the standard, and the controller activates the alarm. Otherwise, the alarm does not sound. The alarm then alerts the patient and medical staff that the current urine volume has met the standard.

[0035] The monitor can display urine flow rate and urine volume values, facilitating monitoring by medical staff or patients.

[0036] After the display shows the urine flow rate and urine volume, medical staff or patients can open the solenoid valve 3 through the controller, and the urine in the inner shell 14 will be discharged through the drain pipe 2.

[0037] Example 2: Based on Example 1, referring to... Figures 1-3 As shown, multiple one-way exhaust components are provided on the side wall of the outer casing 1.

[0038] The one-way exhaust assembly includes a side hole 17 opened on the side wall of the outer shell 1. An inner rod 19 is fixed inside the side hole 17. A connecting rod 18 is fixed on the inner rod 19. A soft rubber cover 4 is fixed to the end of the connecting rod 18 away from the inner rod 19. The soft rubber cover 4 is located on the outside of the outer shell 1 and seals the side hole 17.

[0039] By incorporating a one-way venting assembly, after urine enters the inner shell 14, the gas inside the inner shell 14 and outer shell 1 can be released by pushing open the soft rubber cover 4, thus preventing pressure buildup inside the inner shell 14 and outer shell 1 from affecting the flow rate of urine in the inlet pipe 5. Simultaneously, when the patient is not urinating, this prevents gas from escaping from the inner shell 14 and outer shell 1 and contaminating the indoor environment.

[0040] Example 3: Based on Example 1, referring to... Figure 1 and Figure 2 As shown, a vertical support rod 9 is fixed to the upper end of the outer shell 1, and an arc-shaped tube 8 is fixed to the upper end of the support rod 9. A vertical smooth rod 10, which is a square rod, is fixed to the upper end of the outer shell 1 on one side of the support rod 9. A pressure post 11 is slidably sleeved on the smooth rod 10, and a locking screw 12 is threaded onto the pressure post 11. The locking screw 12 abuts against the outer edge of the smooth rod 10. The free end of the catheter 7 passes through the arc-shaped tube 8 and goes around the lower end of the pressure post 11 before ascending.

[0041] Loosening the locking screw 12 allows adjustment of the position of the pressure post 11 on the smooth rod 10, thereby adjusting the movable length of the catheter 7 and preventing it from becoming too long and tangled.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
