Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an assistive device for patients with spinal cord injury and urinary dysfunction. Background Technology

[0002] Urinary disorders in patients with spinal cord injuries stem from abnormal neural regulation. When the upper motor neurons are damaged, the brain is unable to suppress the spinal micturition reflex, leading to dysco-coordination of the detrusor muscle and sphincter muscles, resulting in spastic bladder and reflex urinary incontinence. When the lower motor neurons are damaged, the bladder detrusor muscle becomes weak and the sphincter muscles become unable to relax, causing flaccid bladder and overflow incontinence. Therefore, patients with spinal cord injuries need to use urination assistance devices.

[0003] Existing assistive devices for patients with urinary dysfunction due to spinal cord injury include, but are not limited to, urinary catheters and related instruments, male urinary cannulas, bladder pressure monitoring devices, portable irrigators, and disinfection devices. Among these, portable irrigators are used to clean the external urethral orifice after intermittent catheterization.

[0004] Currently, portable irrigators used in assistive devices for patients with urinary disorders due to spinal cord injury only allow the waste fluid to flow back into the collection structure under gravity after rinsing the urethral opening. Since this is done solely by gravity, patients inevitably need to change their position, which can easily exacerbate their pain and reduce their comfort. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an assistive device for patients with spinal cord injury and urinary dysfunction. It solves the problem that in existing portable irrigators, the waste liquid after rinsing can only flow back into the collection structure under the action of gravity, which requires patients to change their body position when urinating, thus reducing the comfort of the patient.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see the appendix Figure 1 - Appendix Figure 13 This invention provides an assistive device for patients with spinal cord injury and urinary dysfunction, including a water tank 1. Pressure stabilizing tanks 2 are installed inside both sides of the water tank 1 to maintain stable air pressure. An installation mechanism 3 is installed inside the water tank 1 to install the pressure stabilizing tanks 2. A vacuum pump 4 is fixedly connected inside the water tank 1 to provide air pressure. A connecting mechanism 5 is provided at both the output and input ends of the vacuum pump 4 to connect the vacuum pump 4 and the pressure stabilizing tanks 2. A gas heating mechanism 6 is installed on the top of one of the pressure stabilizing tanks 2 to heat the gas. A water spraying mechanism 7 is installed on one side of the water tank 1 to dispense water. A wastewater collection tank 11 is slidably connected inside the water tank 1. Rotating pipes 9 are rotatably connected to the tops of both pressure stabilizing tanks 2. Automatic valves 8 are fixedly connected to the tops of both the water tank 1 and the wastewater collection tank 11. The end of the rotating pipe 9 away from the pressure stabilizing tank 2 is threadedly connected to an automatic valve. When rinsing outside the valve 8, the air pump 4 is started first. One end of the air pump 4 generates gas, and the other end of the air pump 4 extracts it. If the pressure of the pressure tank 2 is too low, the rotating pipe 9 of the pressure tank 2 can be unscrewed from the automatic valve 8 on the wastewater collection tank 11, so that the outside gas can enter the air pump 4. At this time, the pressure tank 2 filled with gas can pass the gas into the water tank 1. The gas pressure inside the water tank 1 increases, so that the liquid can be sprayed out through the spray mechanism 7 to rinse the urethral opening. When the automatic valve 8 on the water tank 1 is closed and the gas heating mechanism 6 is opened, the gas heating mechanism 6 sprays heated gas to the urethral opening for drying. At the same time, the pressure tank 2 with lower gas pressure can extract the gas in the wastewater collection tank 11, so that the gas pressure in the wastewater collection tank 11 decreases, and the suction is transmitted to the spray mechanism 7 through the wastewater return pipe 14, so that the wastewater can be sucked into the wastewater collection tank 11.

[0022] The mounting mechanism 3 includes two mounting slots 301, which provide mounting space. The two mounting slots 301 are respectively located inside the two sides of the water tank 1. A retaining spring 302 is installed inside each mounting slot 301. A limiting plate 303 is slidably connected inside the mounting slot 301, serving a limiting function. A rod 304 is fixedly connected to the side of the limiting plate 303 closest to the pressure tank 2. The retaining spring 302 can push the limiting plate 303 and the rod 304 to reset. A pin 306 is fixedly connected to one side of the installation mechanism 3. A socket 307 is provided inside the pressure tank 2 on the side away from the pin 306. Two stable mounting holes 308 are provided on the side of the water tank 1 away from the installation mechanism 3. The rod 304 is inserted into the socket 307, and the pin 306 is inserted into the stable mounting holes 308, thus allowing the pressure tank 2 to be installed inside the water tank 1. A pulling post 305 is fixedly connected to the top of the rod 304, facilitating the movement of the rod 304 away from the pressure tank. Pulling the pressure tank 2 in the direction of the pressure vessel causes the insertion rod 304 to engage with the stable mounting hole 308, and the insertion post 306 to be inserted into the stable mounting hole 308. One end of the clamping spring 302 is fixedly connected to the inside of the mounting groove 301, and the other end of the clamping spring 302 is fixedly connected to the end of the limiting plate 303 away from the pressure vessel 2. When disassembling the pressure vessel 2, first remove the two rotating tubes 9 from the two automatic valves 8, and then move the pulling post 305 away from the pressure vessel 2. The insertion rod 304 can be moved away from the pressure stabilizing tank 2, which in turn can move the limiting plate 303 away from the pressure stabilizing tank 2. At this time, the limiting plate 303 can compress the clamping spring 302 and move the pulling column 305 out of the insertion hole 307, and disassemble the connecting mechanism 5. Then, the pressure stabilizing tank 2 is moved towards the mounting mechanism 3, so that the insertion column 306 can be moved out of the stable mounting hole 308. At this time, the pressure stabilizing tank 2 can be disassembled.

[0023] The connecting mechanism 5 includes a fixed tube 501, which provides the installation position and a foundation for ventilation. One end of each of the two fixed tubes 501 is fixedly connected to the output and input ends of the air pump 4, respectively. A push spring 502 is sleeved on the outside of the fixed tube 501. A sliding tube 503 is slidably connected inside the fixed tube 501, serving as a connection and ventilation mechanism. A sealing cap 504 is fixedly connected to the side of the sliding tube 503 away from the air pump 4. A fixing head 505 is fixedly connected to the outside of the pressure tank 2 near the air pump 4. The sealing cap 504 can be fastened to the outside of the fixing head 505, and the push spring 502 can apply force to the sealing cap 504, allowing it to fit tightly against the fixing head 505. The inside of the sealing cap 504 is sleeved on the fixed head 505. Outside the head 505, one end of the push spring 502 is fixedly connected to the outside of the air pump 4, and the other end of the push spring 502 is fixedly connected to the side of the sealing cap 504 near the air pump 4. After the sealing cap 504 is pulled towards the air pump 4, the sliding tube 503 can be moved into the interior of the fixed tube 501, and the sealing cap 504 can be moved away from the interior of the fixed head 505. If it is necessary to install the air pump 4 and the pressure tank 2, the interior of the sealing cap 504 can be aligned with the exterior of the fixed head 505, and the sealing cap 504 can be released. At this time, under the reaction force of the push spring 502, the sealing cap 504 can be pushed back to its original position, so that the sealing cap 504 can be pressed against the exterior of the fixed head 505, thereby completing the connection between the air pump 4 and the pressure tank 2.

[0024] The gas heating mechanism 6 includes a solenoid valve 601, which automatically controls the opening and closing of the gas path. The bottom of the solenoid valve 601 is fixedly connected to the top of one of the pressure stabilizing tanks 2. A bend 602 is rotatably connected to the top of the solenoid valve 601, serving as a connection. A mounting frame 603 is fixedly connected to the end of the bend 602 away from the solenoid valve 601, providing an installation position. A mounting spring 604 is installed inside the mounting frame 603, and a sliding mounting block 605 is slidably connected inside the mounting frame 603, providing an installation position. A mounting cylinder 606 is installed inside the mounting frame 603. When the mounting cylinder 606 is installed inside the mounting frame 603, it can engage with the mounting spring 604. The reaction force of 4 applies a force away from the bend 602 to the sliding mounting block 605, and transmits the force to the mounting cylinder 606, allowing the sliding mounting block 605 to fit tightly against the mounting cylinder 606, thus completing the installation of the mounting cylinder 606. An electric heating wire 607 is fixedly connected inside the mounting cylinder 606, generating heat to heat the air passing through it. A connecting hose 608 is fixedly connected to the bottom of the solenoid valve 601, providing ventilation and reducing the temperature of the air heated by the electric heating wire 607, preventing overheating. The top of the mounting cylinder 606 is located inside the sliding mounting block 605. The bottom of the mounting cylinder 606 is located inside the solenoid valve 601. One end of the mounting spring 604 is fixedly connected to the inside of the mounting frame 603, and the other end of the mounting spring 604 is fixedly connected to the inside of the sliding mounting block 605. When the solenoid valve 601 is opened, gas can enter the inside of the bend 602 through the solenoid valve 601. At this time, the gas is heated by the heating wire 607 in the mounting cylinder 606 and enters the inside of the connecting hose 608. Then, hot gas can be sprayed out by the spray nozzle 710, thereby drying the external urethral opening. When replacing the mounting cylinder 606, move the mounting cylinder 606 towards the bend 602, so that the side of the mounting cylinder 606 away from the bend 602 can be taken out from the notch of the mounting frame 603, thus allowing it to enter... To replace the mounting cylinder 606, when installing the mounting cylinder 606, place one end of the mounting cylinder 606 against the sliding mounting block 605 and push the sliding mounting block 605 upwards. This will cause the sliding mounting block 605 to move towards the top of the mounting frame 603. After the mounting cylinder 606 has completely moved into the mounting frame 603, push the mounting cylinder 606 into the mounting frame 603. After the mounting cylinder 606 has completely entered the mounting frame 603, release the mounting cylinder 606. At this time, under the action of the mounting spring 604, the sliding mounting block 605 will be pushed downwards, and the bottom of the mounting cylinder 606 will be pushed into the mounting frame 603, thus completing the installation of the mounting cylinder 606.

[0025] The water spray mechanism 7 includes a housing 701, which provides an installation position and an air venting position. A resistance spring 702 is installed inside the housing 701. A fixed outer tube 703 is fixedly connected to the side of the housing 701 away from the water tank 1. A limit baffle 704 is slidably connected inside the housing 701, serving a limiting function. A sliding sleeve 705 is fixedly connected to the side of the limit baffle 704 away from the water tank 1. The sliding sleeve 705 can slide inside the fixed outer tube 703, thus providing air venting. The outside of the sliding sleeve 705 is slidably connected to the fixed outer tube 703. Inside the pipe 703, a cavity 706 is formed on the side of the outer casing 701 near the water tank 1. The cavity 706 allows liquid to pass through, providing a space for liquid to soften. Multiple water passages 707 are formed inside the outer casing 701, allowing liquid to pass through. A connecting pipe 708 is fixedly connected inside the outer casing 701 on the side near the water tank 1, serving a connecting function. A water pipe 709 is fixedly connected inside the fixed outer pipe 703 on the side away from the connecting pipe 708, also serving a connecting function. A spray nozzle 7 is fixedly connected to the end of the water pipe 709 away from the water tank 1. 10. The spray cover 710 can fit snugly against the body. The end of the connecting hose 608 away from the water tank 1 is fixedly connected to the outside of the spray cover 710. A water inlet pipe 10 is fixedly connected to the outside of the water tank 1. A drain pipe 12 is fixedly connected to the outside of the wastewater collection tank 11. Both the drain pipe 12 and the water inlet pipe 10 are threaded with sealing caps. A wastewater return pipe 14 is fixedly connected to the outside of the wastewater collection tank 11. The end of the wastewater return pipe 14 away from the wastewater collection tank 11 is fixedly connected to the bottom outside of the spray cover 710. A handle 13 is rotatably connected to the side of the water tank 1 near the spray cover 710. A resistance spring 7 One end of the resistance spring 702 is fixedly connected to the inside of the outer shell 701, and the other end of the resistance spring 702 is fixedly connected to the end of the limiting baffle 704 away from the connecting pipe 708. Under the action of air pressure, the water in the water tank 1 can enter the cavity 706 through the connecting pipe 708 and enter the outer shell 701 through the water passage 707. Thus, the pressure of the water flow can push the limiting baffle 704 to move away from the connecting pipe 708, thereby driving the sliding sleeve 705 to move into the fixed outer tube 703. At this time, the middle of the limiting baffle 704 will no longer be affected by the outer shell 701. The internal baffle blocks the flow of water through the middle of the limiting baffle 704 and the sliding sleeve 705 into the interior of the fixed outer tube 703. The water then flows through the water pipe 709 into the spray nozzle 710, allowing for flushing of the patient's urethral opening. For female flushing, the spray nozzle 710, being made of rubber, can be folded to reduce the distance between the spray nozzle and the patient's urethra, facilitating cleaning of the urethral opening. When no high-pressure water enters, the limiting baffle 704 is reset by the elastic force of the resistance spring 702.This allows the sliding sleeve 705 to reset, and the limiting baffle 704 to block the water passage 707, thus preventing water from flowing into the interior of the outer casing 701 without pressure.

[0026] Working principle: When rinsing, first start the air pump 4. One end of the air pump 4 generates gas, and the other end of the air pump 4 extracts it. If the pressure of the air stabilizing tank 2 is too low, the rotating pipe 9 of the air stabilizing tank 2 can be unscrewed from the automatic valve 8 on the wastewater collection tank 11, so that the outside gas can enter the air pump 4. At this time, the gas-filled pressure stabilizing tank 2 can pass the gas into the water tank 1. The gas pressure inside the water tank 1 increases, so that the liquid can be sprayed out through the spray mechanism 7 to rinse the urethral opening. When the automatic valve 8 on the water tank 1 is closed and the gas heating mechanism 6 is opened, the gas heating mechanism 6 sprays heated gas to the urethral opening for drying. At the same time, the lower pressure of the pressure stabilizing tank 2 can extract the gas in the wastewater collection tank 11, so that the gas pressure in the wastewater collection tank 11 decreases, and the suction is transmitted to the spray mechanism 7 through the wastewater return pipe 14, so that the wastewater can be sucked into the wastewater collection tank 11. When disassembling the pressure stabilizing tank 2, first disconnect the two rotating tubes 9 from the two automatic valves 8. Then, move the pulling column 305 away from the pressure stabilizing tank 2. This will cause the insertion rod 304 to move away from the pressure stabilizing tank 2, and then the limiting plate 303 to move away from the pressure stabilizing tank 2. At this time, the limiting plate 303 can be used to compress the locking spring 302, and the pulling column 305 can be moved out of the insertion hole 307. Then, the connecting mechanism 5 can be disassembled. Then, move the pressure stabilizing tank 2 towards the mounting mechanism 3, so that the insertion column 306 can be moved out of the stable mounting hole 308. At this time, the pressure stabilizing tank 2 can be disassembled. Pulling the sealing cap 504 toward the air pump 4 will cause the sliding tube 503 to move into the interior of the fixed tube 501, and will allow the sealing cap 504 to leave the interior of the fixed head 505. If it is necessary to install the air pump 4 and the pressure tank 2, the interior of the sealing cap 504 can be aligned with the exterior of the fixed head 505, and the sealing cap 504 can be released. At this time, under the reaction force of the push spring 502, the sealing cap 504 can be pushed back to its original position, so that the sealing cap 504 can be pressed against the exterior of the fixed head 505, thereby completing the connection between the air pump 4 and the pressure tank 2. When the solenoid valve 601 is opened, gas can enter the interior of the bend 602 through the solenoid valve 601. At this time, the gas is heated by the heating wire 607 in the mounting cylinder 606 and then enters the interior of the connecting hose 608. The hot gas can then be sprayed out by the spray nozzle 710, thereby drying the external urethral opening. When replacing the mounting cylinder 606, move the mounting cylinder 606 towards the bend 602, so that the side of the mounting cylinder 606 away from the bend 602 can be taken out from the notch of the mounting frame 603, thus replacing the mounting cylinder 606. When installing the mounting cylinder 606, one end of the mounting cylinder 606 is... The mounting cylinder 606 is pressed against the sliding mounting block 605 and pushed upward, thereby moving the sliding mounting block 605 towards the top of the mounting frame 603. After the mounting cylinder 606 has completely moved into the range of the mounting frame 603, the mounting cylinder 606 is pushed into the mounting frame 603. After the mounting cylinder 606 has completely entered the mounting frame 603, the mounting cylinder 606 is released. At this time, under the action of the mounting spring 604, the sliding mounting block 605 can be pushed downward, and the bottom of the mounting cylinder 606 can be pushed into the mounting frame 603, thereby completing the installation of the mounting cylinder 606. Under air pressure, the water in water tank 1 can enter the cavity 706 through the connecting pipe 708 and the outer shell 701 through the water inlet 707. This water pressure then pushes the limiting baffle 704 away from the connecting pipe 708, thereby causing the sliding sleeve 705 to move into the fixed outer tube 703. At this point, the outer shell 701 will no longer be present in the middle of the limiting baffle 704. The internal baffle blocks the flow of water through the middle of the limiting baffle 704 and the sliding sleeve 705 into the interior of the fixed outer tube 703. At this time, the water can enter the interior of the spray nozzle 710 through the water pipe 709, thereby rinsing the patient's urethral opening. If it is for female rinsing, the spray nozzle 710 is made of rubber and can be folded to reduce the distance from the spray nozzle inside the spray nozzle 710 to the patient's urethra, thus facilitating the cleaning of the urethral opening. When no high-pressure water flow enters, the limiting baffle 704 is pushed back to its original position by the elastic force of the resistance spring 702, which in turn pushes the sliding sleeve 705 back to its original position. The limiting baffle 704 then blocks the water hole 707, thus preventing water from flowing into the interior of the outer shell 701 when there is no pressure.
