Description

Technical Field

[0001] This utility model relates to the field of urinary catheterization, specifically a pediatric urinary catheterization device. Background Technology

[0002] Pediatric urinary catheters, also known as urinary catheters, are typically designed specifically for children. They are thin, flexible tubes usually made of medical-grade silicone or natural rubber, offering good biocompatibility and flexibility. One end of the device has a hole or side hole for urine drainage, while the other end connects to a collection bag or drainage system. Inserted into the bladder through the urethra, pediatric urinary catheters establish a direct urine drainage pathway, helping children expel urine. They are primarily used for children experiencing difficulty urinating due to various reasons, such as urethral stricture, urethral injury, or during the recovery period after urinary system surgery. In these cases, children may be unable to urinate. Children need to urinate independently, so a urinary catheter is required to assist with urination. Pediatric catheters are typically made of softer, finer materials than adult catheters to reduce irritation and damage to the urethra. The use of pediatric urinary catheters should be performed by professional medical personnel to ensure proper insertion and fixation. The catheter should be changed regularly to prevent infection and other complications. During use, the catheter and collection bag should be kept clean to reduce the risk of infection. Pediatric urinary catheters are urination assistance devices specifically designed for children, featuring softness, fineness, safety, and comfort. When using them, follow the instructions of professional medical personnel and pay attention to keeping them clean and changing them regularly.

[0003] According to Chinese Patent Publication No. CN215740760U, a pediatric urological catheterization device belongs to the field of medical devices. This pediatric urological catheterization device includes a catheter, a dispensing tank fixedly connected to the lower end of the catheter, a diverting plate rotatably connected inside the dispensing tank, an outlet tube A fixedly connected to the lower right side of the dispensing tank, and an outlet tube B fixedly connected to the lower left side of the dispensing tank. A urine collection bag is connected to the lower end of outlet tube B. This invention allows for convenient and real-time collection of pediatric urine for testing by rotating a knob counterclockwise, which in turn rotates the diverting plate. The rear end of the locking lever engages with the locking groove A on the left side, causing the stop plug to engage with the upper end of outlet tube B. The catheter communicates with outlet tube A through a groove. Removing the dust cap allows for convenient and real-time collection of pediatric urine for testing. This invention has a compact structure and is easy to operate.

[0004] In the above solution, by engaging the stop plug with the upper end of the outlet tube B, the catheter connects to the outlet tube A via a groove. Removing the dust cap allows for convenient and real-time collection of pediatric urine for testing. However, this method has the following drawbacks: The existing pediatric urinary catheterization device is not secured during use, making it prone to shaking and potentially causing the catheter to fall out, affecting normal catheterization and increasing discomfort for the child. The unsecured device is also prone to movement during the child's activity, potentially irritating the urethra and causing urethral mucosal damage, increasing the child's pain and reducing safety and comfort. Furthermore, because pediatric catheters are typically thinner than adult catheters, thorough cleaning of the inside is impossible after use, increasing the risk of infection during subsequent use, further irritating and damaging the child's urethra, and increasing the risk of urinary tract infections. Utility Model Content

[0005] The purpose of this invention is to provide a pediatric urinary catheterization device to solve the problem that existing pediatric urinary catheterization devices are not fixed in place, which can easily cause them to shake during use, leading to the catheter falling off, affecting the normal catheterization of children, and increasing their discomfort.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a pediatric urinary catheterization device, comprising a fixing plate, a support plate fixedly connected to one side of the fixing plate, a motor fixedly connected to one side of the support plate, a fixing component for strengthening the fixation on the motor, an adjuster on one side of the fixing plate, and a rotating component for quick installation and cleaning on the adjuster.

A telescopic rod is fixedly connected to one end of the rotating shaft, and an adjusting block is fixedly connected to one end of the telescopic rod. A worm gear is slidably connected to one side of the adjusting block. A worm wheel is disposed on the worm gear, and the worm gear meshes with the worm wheel. A bidirectional threaded rod is disposed on the worm wheel, and the outer wall of the bidirectional threaded rod is fixedly connected to the worm wheel. A connecting plate is threadedly connected to the bidirectional threaded rod, and a clamping leg ring is fixedly connected to the bottom surface of the connecting plate.

[0008] Preferably, the outer wall of the telescopic rod is rotatably connected to a first adapter plate, the first adapter plate being rotatably connected to a bidirectional threaded rod, and the output end of the motor is rotatably connected to a second adapter plate, the second adapter plate being rotatably connected to a rotating shaft.

[0009] Preferably, the rotating assembly includes a housing, which is fixedly connected to the regulator. The housing has a sliding groove, and a urinary catheter is disposed inside the housing.

[0013] Beneficial effects:

[0014] 1. In use, the leg clamps are placed on the child's legs, and the worm gear on the leg clamps is inserted into the adjusting block for fixation. Moving the two leg clamps outwards moves the telescopic rod outwards to the appropriate position. The motor then starts, driving the first bevel gear to rotate. This first bevel gear then drives the meshing second bevel gear to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the telescopic rod to rotate, which in turn drives the adjusting block to rotate. The adjusting block then drives the worm gear to rotate, which in turn drives the meshing worm wheel to rotate. The worm wheel then drives the double-threaded rod to rotate, which in turn moves the two threaded connecting plates. These connecting plates then move the leg clamps inwards to fix them to the child's legs, achieving quick and secure fixation of the catheter. The operation is simple and quick, ensuring the catheter is more stably fixed to the child, reducing the risk of dislodgement. It can be adjusted according to body shape, improving flexibility and comfort. Attached Figure Description

The fixing component includes a first bevel gear 4 fixedly connected to the output end of the motor 3, a second bevel gear 5 on the first bevel gear 4, and the first bevel gear 4 meshing with the second bevel gear 5, a rotating shaft 6 on the second bevel gear 5, the outer wall of the rotating shaft 6 fixedly connected to the second bevel gear 5, a telescopic rod 7 fixedly connected to one end of the rotating shaft 6, an adjusting block 8 fixedly connected to one end of the telescopic rod 7, a worm gear 9 slidably connected to one side of the adjusting block 8, a worm wheel 10 on the worm gear 9, the worm gear 9 meshing with the worm wheel 10, a bidirectional threaded rod 11 on the worm wheel 10, and the outer wall of the bidirectional threaded rod 11... A connecting plate 12 is threaded onto the bidirectional threaded rod 11, which is fixedly connected to the worm gear 10. A clamping leg ring 13 is fixedly connected to the bottom surface of the connecting plate 12. A first adapter plate 14 is rotatably connected to the outer wall of the telescopic rod 7. The first adapter plate 14 is rotatably connected to the bidirectional threaded rod 11. A second adapter plate 15 is rotatably connected to the output end of the motor 3. The second adapter plate 15 is rotatably connected to the rotating shaft 6. The rotating assembly includes a housing 17, which is fixedly connected to the adjuster 16. A section is opened on the housing 17. The sliding groove 18 and the inner shell 17 are provided with a urinary catheter 19. A slider 20 is fixedly connected to the outer wall of the urinary catheter 19. A circular groove is opened on the slider 20. A fixing rod 21 is provided on the top surface of the slider 20. A tube head 22 is fixedly connected to one side of the urinary catheter 19. The slider 20 is slidably connected to the outer shell 17. A liquid outlet groove is opened on the tube head 22. A reinforcing plate is fixedly connected to the top of the fixing rod 21. A urine storage box 23 is provided on one side of the regulator 16. A three-chamber device 24 is installed on one side of the urine storage box 23.

[0023] In use, the leg clamps 13 are placed on the child's legs, and the worm gear 9 on the leg clamps 13 is inserted into the adjusting block 8 for fixation. Moving the two leg clamps 13 outwards causes the telescopic end of the telescopic rod 7 to move outwards to a suitable position. Then, the motor 3 is started, driving the first bevel gear 4 to rotate. The first bevel gear 4 then drives the meshing second bevel gear 5 to rotate. The second bevel gear 5 then drives the rotating shaft 6 to rotate, which in turn drives the telescopic rod 7 to rotate. Finally, the telescopic rod 7 drives the adjusting block 8 to rotate. The leg clamp 13 can be inserted into the adjustment block 8 according to the usage angle. At this time, the adjustment block 8 drives the worm gear 9 to rotate, and then the worm gear 9 drives the meshing worm wheel 10 to rotate. Then the worm wheel 10 drives the double-threaded rod 11 to rotate, and then the double-threaded rod 11 drives the two threaded connecting plates 12 to move. At this time, the connecting plates 12 drive the leg clamp 13 to move inward and fix it on the child's leg, realizing quick and strong fixation of the urinary catheter. The operation is simple and quick, so that the urinary catheter 19 can be more stably fixed on the child and reduce the risk of dislodgement. The device can be adjusted according to body shape, improving flexibility and comfort, reducing discomfort caused by improper fixation, making the catheter more stable during use, improving safety, and reducing the risk of infection. Moving the catheter 19 moves the slider 20 outwards, and then the slider 20 slides on the groove 18 on the outer shell 17. At this time, the catheter 19 moves the tube head 22 outwards and gently inserts it into the urethra to the bladder. Then, sterile water is injected into the catheter 19. When it is necessary to clean the catheter 19, the fixing rod 21 is rotated. Next, move the slider 20 down to release it from sliding with the groove 18. Then, remove the catheter 19 from the outer casing 17 and place it into the cleaner for quick cleaning. This allows for rapid cleaning of the catheter 19, making it easier to clean and improving its cleanliness and hygiene. It effectively removes contaminants from the catheter, reduces bacterial growth, and regular cleaning can reduce the number of bacteria, thereby lowering the risk of infection. Regular cleaning can also remove dirt and bacteria, reduce wear and corrosion on the device, extend the device's lifespan, and improve children's comfort.
