Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more particularly to a urinary catheter protection device. Background Technology

[0002] Patients who have undergone urological surgery usually have a urinary catheter left in place to facilitate urination. The catheter needs to be secured, otherwise it is easy for it to fall out as the patient moves, causing secondary injury to the patient. Furthermore, catheter dislodgement can easily lead to urinary tract infections.

[0003] Currently, when fixing urinary catheters, adhesive tape is generally used to wrap and secure them to the abdomen or leg. However, when using adhesive tape, some patients may have allergic reactions to the adhesive material, and the tape is easily loosened by the patient's bodily fluids, which can affect the fixation of the urinary catheter. Furthermore, tearing the tape can also cause damage to the patient's skin.

[0004] In conclusion, there is a need to develop a catheter protection device that does not require tape fixation and will not damage the skin. Summary of the Invention

[0005] In order to overcome the shortcomings of existing technologies that use tape to fix urinary catheters, such as allergic reactions to the adhesive material of the tape in some patients and the tape easily falling off due to the patient's bodily fluids, this invention provides a urinary catheter protection device that does not require tape fixation and will not damage the skin.

[0006] To achieve the above objectives, the present invention provides the following solution: a catheter protection device comprising an arc-shaped plate, connecting rods, a Velcro strap, soft wheels, and a fixing component. The arc-shaped plate is fixedly connected to symmetrically arranged connecting rods. One of the symmetrically arranged connecting rods is uniformly fixedly connected to the Velcro strap, which wraps around the other connecting rod. The soft wheels are rotatably connected to the arc-shaped plate at uniform intervals. The top of the arc-shaped plate is provided with a fixing component for limiting the catheter position.

[0007] To further explain, the fixing assembly includes a slide box, an angled column, a large pressure plate, a first return spring, a side pressure plate, and a second return spring. The top of the arc-shaped plate is fixedly connected to the symmetrically arranged slide boxes. The symmetrically arranged angled columns are slidably connected to each of the symmetrically arranged slide boxes. The side pressure plates are fixedly connected to each of the symmetrically arranged angled columns. The large pressure plate is slidably connected to each of the angled columns. The first return spring is connected between the large pressure plate and the angled column. The second return spring is connected between each of the symmetrically arranged angled columns and the adjacent slide box.

[0008] To further explain, the angled post and the large pressure plate are used to clamp and fix the urinary catheter.

[0009] Further explanation: It also includes a round-headed perforated plate, a cylinder, a limiting frame, and a third return spring. The top of the arc-shaped plate is fixedly connected to the symmetrically arranged round-headed perforated plates. The symmetrically arranged cylinders are slidably connected between the symmetrically arranged round-headed perforated plates at even intervals. The limiting frame is fixedly connected to the opposite side of each of the symmetrically arranged round-headed perforated plates. The symmetrically arranged cylinders are all slidably connected to the limiting frame. The third return spring is connected between each of the symmetrically arranged cylinders and the limiting frame. The top of the arc-shaped plate is provided with a driving component for pressing the cylinder to move.

[0010] Further explanation: The drive assembly includes a slant plate frame, a slide rail frame, long threaded rods, a motor, a first transmission assembly, and large fixed rings. The motor is mounted on the top of the arc-shaped plate. The slide rail frames are symmetrically arranged and fixed to the top of the arc-shaped plate. The large fixed rings are symmetrically arranged and fixed to the top of the arc-shaped plate. The long threaded rods are rotatably connected to the large fixed rings on the same side as the symmetrically arranged slide rail frames. The symmetrically arranged long threaded rods are threadedly connected to the slant plate frame on the side closest to the motor. The symmetrically arranged slant plate frames are slidably connected to the slide rail frames. The first transmission assembly is connected between the symmetrically arranged long threaded rods and the output shaft of the motor.

[0011] To further explain, the inclined plate moves and contacts the cylinder, and the contact position between the inclined plate and the cylinder is V-shaped. The movement of the inclined plate squeezes the cylinder to move towards each other, thereby squeezing and clearing the catheter.

[0012] Further explanation: The system also includes square column rods, small fixed rings, bidirectional threaded rods, a circular hole disc, a locking pin, and a second transmission assembly. The arc-shaped plate is fixedly connected to symmetrically arranged small fixed rings. Adjacent small fixed rings are rotatably connected to the bidirectional threaded rods. The circular hole disc is fixedly connected to the end of each bidirectional threaded rod. The arc-shaped plate has a positioning hole on the side near the circular hole disc that mates with it. The locking pin is placed on the circular hole disc and is engaged within the positioning hole of the arc-shaped plate. The symmetrically arranged bidirectional threaded rods are threadedly connected to symmetrically arranged square column rods. All symmetrically arranged square column rods pass through the arc-shaped plate and are slidably connected to it. The second transmission assembly connects the symmetrically arranged bidirectional threaded rods.

[0013] Further explanation: The system also includes air boxes, compression bags, one-way air inlet valves, connecting rods, arc-shaped water tanks, and connecting pipes. The air boxes are symmetrically arranged and fixed within the arc-shaped plate. Each of the symmetrically arranged air boxes is connected to a compression bag. Each of the symmetrically arranged inclined plate frames is fixed to an adjacent compression bag with a connecting rod. Each of the symmetrically arranged air boxes is connected to a one-way air inlet valve. The arc-shaped water tanks are symmetrically arranged and fixed within the arc-shaped plate. The air boxes are connected to the arc-shaped water tanks, and a one-way valve is connected to the connection point between the air boxes and the arc-shaped water tanks. The bottoms of each of the symmetrically arranged arc-shaped water tanks are connected to evenly arranged connecting pipes, and each evenly arranged connecting pipe is in contact with an adjacent flexible roller.

[0014] To further explain, during the process of the inclined plate frame moving and squeezing the cylinder, it drives the connecting rod to squeeze the compression bag, and the compression bag pushes the gas in the gas box into the arc-shaped water tank to pressurize the arc-shaped water tank.

[0015] Further explanation: It also includes a movable cover, a round rod handle, locking double rods and connecting short rods. The movable covers are fixed to the oblique columns on the same vertical side through the connecting short rods. The symmetrically arranged movable covers are all opened with locking holes. The locking double rods are placed between the locking holes of the symmetrically arranged movable covers. The round rod handles are fixed to the top of the movable covers.

[0016] The present invention has at least one of the following advantages: The present invention uses Velcro to fix the arc-shaped plate to the patient's thigh, and then uses the side pressure plate and the large pressure plate to fix the urinary catheter. In this way, there is no need to use tape to fix the urinary catheter, which can avoid the patient's allergic reaction to the adhesive of the tape, and can also prevent the tape from falling off due to the patient's body fluids, thereby affecting the fixation effect of the urinary catheter, avoiding secondary injury to the patient caused by the urinary catheter falling off, and preventing the urinary catheter from falling off and causing urinary tract infection.

[0017] By using an inclined plate to press the cylinders in opposite directions, the cylinders squeeze the catheter in sequence, creating a peristaltic effect that helps to clear the catheter and prevent blockage from affecting the patient's urination.

[0018] The catheter can be clamped by moving the square column and round rod in opposite directions, thereby changing the speed of urination and preventing a sudden drop in bladder pressure caused by excessively fast urination, which could lead to bladder mucosal bleeding.

[0019] By rotating the curved plate, the soft rollers can be driven to rotate. The friction between the soft rollers and the patient's skin causes the soft rollers to rotate, thereby applying the soothing medication to the patient's legs. In this way, the patient's skin can be soothed, avoiding muscle damage caused by prolonged binding. The applied medication can also improve lubrication and facilitate the movement of the curved plate.

[0020] The locking double rods are locked in the locking holes of the movable cover, so that the movable cover covers the catheter and cylinder, which can cover and protect the catheter and cylinder and other components to prevent damage to the catheter. Attached Figure Description

Detailed Implementation

[0036] The invention will now be described more fully below with reference to the accompanying drawings, in which presently preferred embodiments of the invention are illustrated. However, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and to fully convey the scope of the invention to those skilled in the art.

[0037] Example 1: Catheter protection device, please refer to Figures 1-4 The device includes an arc-shaped plate 1, a connecting round rod 2, a Velcro strap 3, flexible wheels 5, and a fixing assembly. The arc-shaped plate 1 is fixedly connected to the symmetrically arranged connecting round rods 2. The Velcro strap 3 is uniformly fixedly connected to the connecting round rod 2 on the left side. The Velcro strap 3 passes around the connecting round rod 2 on the right side. The flexible wheels 5 are rotatably connected to the top of the arc-shaped plate 1 at uniform intervals. The top of the arc-shaped plate 1 is provided with a fixing assembly, which is used to limit the position of the conduit.

[0038] The fixing assembly includes a slide box 6, an angled column 7, a large pressure plate 8, a first return spring 9, a side pressure plate 10, and a second return spring 11. The slide box 6 is fixedly connected to both the front and rear sides of the top of the arc plate 1. Two angled columns 7 are slidably connected inside each of the two slide boxes 6. The side pressure plate 10 is fixedly connected to the inner side of each of the two angled columns 7. The large pressure plate 8 is slidably connected to the upper part of the two angled columns 7 on the right side. The first return spring 9 is connected between the large pressure plate 8 and the angled column 7. The second return spring 11 is connected between each of the four angled columns 7 and the adjacent slide box 6.

[0039] Post-urology surgery patients often have indwelling catheters for urination. To avoid allergic reactions to adhesive tape used to secure the catheter in some patients, and to prevent the tape from coming off due to bodily fluids and affecting its fixation, the Velcro strap 3 can be opened. The curved plate 1 is then placed on the patient's thigh and secured with the Velcro strap 3. The angled post 7 is then pulled outwards, causing the side pressure plate 10 to move outwards, stretching the second return spring 11. The catheter is then placed between the side pressure plates 10. The angled post 7 is then released, resetting the second return spring 11 and causing the angled post 7 to move inwards, thus resetting the side pressure plate 10. The side pressure plate 10 moves inward to reset and clamp the catheter. During the inward movement of the side pressure plate 10, the large pressure plate 8 is manually moved upward, stretching the first reset spring 9. After the side pressure plate 10 clamps the catheter, the large pressure plate 8 is then released, and the first reset spring 9 resets, causing the large pressure plate 8 to move downward to reset and cooperate with the side pressure plate 10 to clamp and fix the catheter. In this way, there is no need to use tape to fix the catheter, avoiding patient allergies to tape and preventing tape from falling off due to the patient's body fluids, which would affect the fixation effect of the catheter and prevent secondary injury to the patient caused by catheter dislodgement. Furthermore, catheter dislodgement can easily lead to urinary tract infections.

[0040] Example 2: Based on Example 1, please refer to... Figure 1 and Figures 5-14 It also includes a round-headed perforated plate 12, a cylinder 13, a limiting frame 14, and a third return spring 15. The round-headed perforated plates 12 are fixedly connected to the left and right sides of the top of the arc plate 1. Multiple sets of cylinders 13 are slidably connected between two round-headed perforated plates 12 at even intervals. Each set of two cylinders 13 forms a set. The limiting frame 14 is fixedly connected to the outer side of two round-headed perforated plates 12. Each set of cylinders 13 is slidably connected to the limiting frame 14. The third return spring 15 is connected between each set of cylinders 13 and the limiting frame 14. A driving assembly is provided at the top of the arc plate 1. The driving assembly is used to squeeze the cylinders 13 to move.

[0041] The drive assembly includes a slant plate frame 16, a slide rail frame 17, a long threaded rod 18, a motor 19, a first transmission assembly 20, and large fixed rings 21. The motor 19 is mounted on the front top of the arc-shaped plate 1. The slide rail frame 17 is fixed to both the left and right sides of the top of the arc-shaped plate 1. Symmetrically arranged large fixed rings 21 are fixed to both the left and right sides of the top of the arc-shaped plate 1. The long threaded rod 18 is rotatably connected between the two large fixed rings 21 on the left and right sides. The slant plate frame 16 is threaded to the front of each of the two long threaded rods 18. The inclined plate frame 16 is slidably connected to the adjacent slide frame 17. The inclined plate frame 16 moves to contact the cylinder 13. The contact position between the inclined plate frame 16 and the cylinder 13 is V-shaped. The inclined plate frame 16 moves to squeeze the cylinder 13 and move towards each other to squeeze and clear the catheter. The front sides of the two long threaded rods 18 are connected to the output shaft of the motor 19 with a first transmission assembly 20. The first transmission assembly 20 consists of a pulley and a belt. The pulley is connected to the front side of the long threaded rod 18, and the belt is wound around the pulley.

[0042] To prevent the urinary catheter from being blocked by stones, blood clots, or other foreign objects, which could affect urination and cause bladder swelling and pain, and in severe cases even bladder rupture, the urinary catheter can be cleared when blocked. This is achieved by activating the motor 19, whose output shaft drives the long threaded rod 18 to rotate via the first transmission assembly 20. This, in turn, moves the inclined plate frame 16 backward, pressing against the cylinder 13. The third return spring 15 is compressed, causing the cylinder 13 to compress the urinary catheter. When the inclined plate frame 16 moves to a position opposite the cylinder 13... During separation, the third return spring 15 resets, causing the cylinder 13 to move outwards to release the catheter. Thus, under the action of the inclined plate frame 16, the evenly distributed cylinders 13 are sequentially squeezed, causing the evenly distributed cylinders 13 to squeeze the catheter in sequence, thereby creating a peristaltic effect, which can clear the catheter and prevent the catheter from being blocked and affecting the patient's urination. Then, the output shaft of the motor 19 is controlled to reverse, and the output shaft of the motor 19 drives the long threaded rod 18 to reverse and reset, thereby driving the inclined plate frame 16 to move forward and reset. After the process is completed, the motor 19 is turned off.

[0043] It also includes a square column rod 22, a small fixing ring 23, a bidirectional threaded rod 24, a circular hole plate 25, a locking pin 26, and a second transmission assembly 27. The small fixing rings 23 are symmetrically arranged and fixed to both the front and rear sides of the arc-shaped plate 1. The bidirectional threaded rods 24 are rotatably connected between the front and rear small fixing rings 23. The bidirectional threaded rods 24 are symmetrically arranged. The circular hole plate 25 is fixed to the right end of the front bidirectional threaded rod 24. A positioning hole that mates with the circular hole plate 25 is opened on the right front side of the arc-shaped plate 1. The locking pin 26 is placed on the perforated plate 25 and is locked in the positioning hole of the arc plate 1. The two bidirectional threaded rods 24 are threadedly connected to two square column round rods 22. Both square column round rods 22 pass through the arc plate 1 and are slidably connected to the arc plate 1. The second transmission assembly 27 is connected between the left sides of the two bidirectional threaded rods 24. The second transmission assembly 27 consists of a pulley and a belt. The pulley is connected to the left side of the bidirectional threaded rod 24 and the belt is wrapped around the pulley.

[0044] To prevent excessively rapid urination from the catheter, which could cause a sudden drop in bladder pressure and lead to bladder mucosal bleeding, the urination rate can be controlled. The locking pin 26 is manually removed, and then the circular plate 25 is rotated. The circular plate 25 drives the bidirectional threaded rod 24 to rotate, which in turn drives the square column rod 22 to move in opposite directions. This movement of the square column rod 22 clamps the catheter, thus altering the urination rate and preventing a sudden drop in bladder pressure caused by excessively rapid urination, which could lead to bladder mucosal bleeding. After adjustment, the locking pin 26 is reset. This positions the square column rod 22, preventing it from loosening and affecting the control of the urination rate.

[0045] It also includes an air box 28, a compression bag 29, a one-way air inlet valve 30, a connecting rod 3001, an arc-shaped water tank 31, and a connecting pipe 32. The air boxes 28 are symmetrically arranged and fixed to the rear side of the inside of the arc-shaped plate 1. Both air boxes 28 are connected to the compression bags 29. The compression bags 29 are located inside the arc-shaped plate 1. The two inclined plate frames 16 are fixed to the adjacent compression bags 29 with the connecting rod 3001. Both air boxes 28 are connected to the one-way air inlet valve 30. Two arc-shaped water tanks 31 are fixed inside the arc-shaped plate 1. Both air boxes 28 are connected to the adjacent arc-shaped water tanks 31. A one-way valve is connected to the connection part between the air box 28 and the arc-shaped water tank 31. The bottom of both arc-shaped water tanks 31 is connected to the evenly arranged connecting pipes 32. The evenly arranged connecting pipes 32 are in contact with the adjacent flexible wheels 5.

[0046] To prevent discomfort caused by prolonged binding of the patient's legs with the Velcro strap 3, the curved plate 1 can be rotated appropriately. During rotation, a soothing medication can be applied to the patient's legs. First, the soothing medication is placed in the arc-shaped water tank 31. When the inclined plate frame 16 moves, it moves the connecting rod 3001, which in turn compresses the compression bag 29, pushing the air from the air box 28 into the arc-shaped water tank 31. This pressurizes the interior of the arc-shaped water tank 31, causing the soothing medication to flow through the connecting pipe 32 onto the soft wheel 5. Then, the curved plate 1 can be manually rotated for movement. The curved plate 1 drives the soft wheel 5 to rotate. Under the friction between the soft wheel 5 and the patient's skin, the soft wheel 5 rotates, thereby applying the soothing medicine to the patient's leg. In this way, the patient's skin can be soothed, avoiding muscle damage caused by prolonged binding. The applied medicine can also improve lubrication and facilitate the movement of the curved plate 1. When the inclined plate frame 16 moves forward and resets, it drives the compression bag 29 to extend and reset, thereby drawing outside air into the arc-shaped water tank 31 through the one-way air inlet valve 30. Under the action of the one-way valve between the arc-shaped water tank 31 and the air box 28, water in the arc-shaped water tank 31 can be prevented from entering the air box 28.

[0047] It also includes a movable cover 33, a round rod handle 34, a locking double rod 35, and a connecting short rod 36. The movable cover 33 is fixed between the two oblique columns 7 on the left and between the two oblique columns 7 on the right through the connecting short rod 36. The movable covers 33 are symmetrically arranged. The two movable covers 33 have locking holes on the front and rear sides of the upper part. The locking double rod 35 is placed between the adjacent locking holes of the two movable covers 33. The top of the two movable covers 33 is fixed with two round rod handles 34.

[0048] To prevent damage to the catheter and components such as the cylinder 13, the catheter and components can be covered for protection. When the catheter needs to be placed, the locking double rod 35 is removed, and then the round rod handle 34 is grasped to push the movable cover 33 outward to open it. The movable cover 33 moves the angled column 7 outward, and the second return spring 11 is stretched. Then, the catheter is placed between the side pressure plate 10 and the large pressure plate 8. After the catheter is placed, the round rod handle 34 is released. Under the reset action of the second return spring 11, the angled column 7 moves inward to reset, which in turn moves the movable cover 33 and the round rod handle 34 inward to reset. Then, the locking double rod 35 is locked in the locking hole of the movable cover 33. In this way, the movable cover 33 can be locked, thereby protecting the catheter and components such as the cylinder 13 and preventing damage to the catheter.
