Abstract

This invention provides an external fixation device for a balloon catheter used in clinical nursing, belonging to the field of medical devices. It includes a mounting box, with a fixing rod fixedly connected to the inner surface of the mounting box. A buffer assembly is provided on the outer side of the fixing rod. The buffer assembly includes a winding part and a movable part. The winding part includes a movable sleeve rotatably connected to the outer surface of the fixing rod. By setting the buffer assembly, the catheter can be wound and stored by a guide frame, keeping the length of the catheter outside the mounting box within an appropriate range. This effectively reduces the risk of accidental pulling on the catheter. The movement of the guide frame releases the catheter, buffering and absorbing the pulling force on the catheter, thereby effectively reducing the transmission of pulling force to the balloon catheter. This reduces the probability of damage to the patient's bladder and urethra caused by the balloon catheter during accidental patient movement, thus effectively ensuring comfort during the operation of the catheterization device.

Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to an external fixation device for a balloon catheter used in clinical care. Background Technology

[0002] A balloon catheter is a medical device mainly used in the medical field, especially in the diagnosis and treatment of urinary system diseases. Its principle is to use the property of the balloon to expand after the fluid is injected, so that it fits tightly against the inner wall of the bladder or urethra, thereby playing a fixing role and preventing the catheter from falling out. It is widely used in urological surgery, postoperative care, and urine drainage for patients who are bedridden for a long time.

[0003] In the prior art, balloon catheters are usually left in the patient's body and drain urine into an external urine bag. In order to make it convenient for patients to carry, the external catheter and urine bag need to be fixed. For example, Chinese patent with authorization announcement number CN111298270B discloses an external fixation device for balloon catheters for clinical care. The catheter is fixed to the outside of the body by means of straps and a buffer structure. The buffer structure can minimize the impact of body shaking on the catheter and reduce the pain and discomfort of the user.

[0004] Existing balloon catheter external fixation devices, by incorporating a buffer mechanism between the strap and the housing, can reduce the swaying of the catheter during changes in patient position to some extent. However, in clinical use, the catheter extends from the patient's bladder into the urine bag. When the patient turns over or changes position, the catheter is easily pulled by bed rails or bedding. When the catheter is pulled, the external force is transmitted to the patient's bladder through the catheter, which not only increases the risk of damage to the patient's bladder and urethra from the catheter, but also makes it inconvenient for the patient to turn over.

[0018] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0019] In the above solution, by setting up a buffer component, the catheter is wound and stored by a guide frame, so that the length of the catheter outside the installation box is within an appropriate range. At the same time, it can effectively reduce the risk of the catheter being accidentally pulled. By moving the guide frame, the catheter is released and the pulling force on the catheter is buffered and absorbed, thereby effectively reducing the transmission of pulling force to the balloon catheter. This reduces the probability of the balloon catheter causing damage to the patient's bladder and urethra during accidental patient activity, and thus effectively ensures the comfort of the catheterization device during operation.

[0020] By setting up buffer component two, the guide frame can be rotated to release the catheter wound on its surface.

[0021] By setting up adjustment components, the rotational resistance of the movable sleeve can be maintained within an appropriate range by changing the position of the push rod. This effectively reduces the probability of the movable sleeve and connecting plate rotating unexpectedly due to changes in the patient's position, thereby further improving the stability of the fixation device.

[0041] like Figures 1 to 10 As shown, this embodiment of the invention provides an external fixation device for a balloon catheter used in clinical nursing, including an installation box 11. A fixing rod 17 is fixedly connected to the inner surface of the installation box 11. A buffer assembly is provided on the outer side of the fixing rod 17. The buffer assembly includes a winding part and a movable part. The winding part includes a movable sleeve 18 that is rotatably connected to the outer surface of the fixing rod 17. A connecting plate 19 is fixedly connected to the outer surface of the movable sleeve 18. There are two sets of connecting plates 19, which are arranged in parallel.

[0042] The movable part includes guide grooves 20 respectively opened on the outer surface of two sets of connecting plates 19. A guide frame 22 is slidably connected to the inner surface of the guide groove 20. A traction bar 21 is fixedly connected to the outer surface of the guide frame 22 away from the movable sleeve 18. The end of the traction bar 21 away from the guide frame 22 is fixedly connected to the inner surface of the guide groove 20. The guide frame 22 is used to wind the guide tube 13.

[0043] The upper end of the catheter 13 is fixedly connected to the vesicoves and ureters. The guide grooves 20 and guide frames 22 are in several groups and arranged in a ring array. The traction strip 21 is made of elastic material. The outer surface of the front end of the mounting box 11 is fixedly connected to a cable tie 12, and the outer surface of the cable tie 12 is provided with Velcro.

[0044] By adopting the above technical solution, during use, the installation box 11 is first fixed and limited by tying the cable tie 12 to the patient's thigh. The Velcro on the surface of the cable tie 12 allows for quick installation. After the installation box 11 is fixed, the upper end of the catheter 13 is connected to the balloon catheter. The upper end of the balloon catheter 13 is located inside the patient's bladder for catheterization. When the patient turns over or moves accidentally, the catheter 13 and the balloon catheter can be easily pulled. Pulling the balloon catheter can damage the patient's bladder and greatly increase the patient's pain. Therefore, a buffer component is set up. The installation box 11 is supported by the fixed rod 17 for rotation of the movable sleeve 18. The movable sleeve 18 is used to fix and support the two sets of connecting plates 19. The guide groove 20 on the surface of the connecting plate 19 is used for sliding guidance of the guide frame 22. The elastic material traction strip 21 is used for traction support of the guide frame 22, while part of the catheter is... The catheter 13 is wound around the outside of the guide frame 22 in a ring array, which can reduce the probability of excessive bending of the catheter 13. At the same time, it can wind a certain length of the catheter 13 around the outside of the guide frame 22, so that the length of the catheter 13 outside the installation box 11 is within an appropriate range. It can also effectively reduce the risk of the catheter 13 being pulled accidentally. When the catheter 13 is pulled accidentally, the guide frame 22 will move to one side of the movable sleeve 18 and stretch the traction bar 21. At this time, the catheter 13 wound around the surface of the guide frame 22 will contract and converge towards the movable sleeve 18, thereby releasing the catheter 13 on the surface of the guide frame 22 and buffering and absorbing the pulling force on the catheter 13. This can effectively reduce the transmission of pulling force to the balloon catheter 13, thereby reducing the probability of the balloon catheter 13 causing damage to the patient's bladder and urethra when the patient moves accidentally, and thus effectively ensuring the comfort of the catheterization device during operation.

[0045] like Figure 5 and Figure 7 As shown, a second buffer assembly is provided inside the mounting box 11. The second buffer assembly includes a slot 41 formed on the inner surface of the mounting box 11. The slot 41 is arc-shaped. A movable plate 42 is fixedly connected to the outer surface of the connecting plate 19 near the slot 41. The end of the movable plate 42 away from the connecting plate 19 extends through to the inside of the slot 41 and slides in contact with the inner surface of the slot 41. A tension spring 43 is fixedly connected to the outer surface of the movable plate 42. The end of the tension spring 43 away from the movable plate 42 is fixedly connected to the inner surface of the slot 41.

[0046] By adopting the above technical solution, in order to further improve the buffering effect of catheter 13, a second buffer component is set up. When one end of catheter 13 is pulled, catheter 13 will first drive several sets of guide frames 22 to converge. When the guide frames 22 move to the surface of the movable sleeve 18, they will stop moving. At this time, catheter 13 wrapped around the surface of guide frames 22 cannot continue to be released. When the external pulling force continues to exist, catheter 13 will drive the movable sleeve 18 to rotate through guide frames 22 and connecting plate 19. The rotation of connecting plate 19 and guide frames 22 can release catheter 13 wrapped around its surface. During the movement, connecting plate 19 will drive moving plate 42 to slide along the inside of slot 41. During the movement, moving plate 42 will pull tension spring 43. The elasticity of tension spring 43 can buffer and offset the pulling force on catheter 13, thereby further reducing the discomfort caused to the patient when catheter 13 is pulled, and thus effectively improving the buffering effect of pulling force.

[0047] like Figure 4 and Figure 10 As shown, an adjustment component is provided on the inner side of the fixing rod 17. The adjustment component includes a cavity 49 embedded in the inner side of the fixing rod 17. A push rod 45 is movably connected to the inner side of the cavity 49. The front end of the push rod 45 extends through to the outside of the mounting box 11 and is screw-driven to the mounting box 11. The rear side of the outer surface of the push rod 45 is conical. A through hole 52 is provided on the outer surface of the fixing rod 17. A top rod 48 is slidably connected to the inner side of the through hole 52.

[0048] The movable sleeve 18 has a recessed groove 46 embedded in its inner side. The recess 46 is annular. The upper end of the push rod 48 is conical and extends into the inner side of the recess 46. A friction block 47 is fixedly connected to the inner surface of the recess 46. The upper end of the push rod 48 is in rotatable contact with the outer surface of the friction block 47. The friction block 47 is made of elastic wear-resistant material. The lower end of the push rod 48 is arc-shaped and is in movable contact with the outer surface of the push rod 45.

[0049] By adopting the above technical solution, when the buffer assembly is working, the rotational sensitivity of the connecting plate 19 of the movable sleeve 18 needs to be adjusted to reduce the probability of accidental rotation of the movable sleeve 18 and the connecting plate 19 due to changes in the patient's body position. For this purpose, an adjustment component is set up. When it is necessary to increase the rotational resistance of the movable sleeve 18, the operator rotates the push rod 45. The push rod 45 is connected to the mounting box 11 via a screw drive. As the push rod 45 rotates, it slides into the cavity 49. During the movement, the inclined area of ​​the push rod 45 contacts the lower outer surface of the top rod 48. The movement of the push rod 45 moves the top rod 48 upward along the through hole 52. As the push rod 48 gradually moves into the limiting groove 46, its upper end contacts the friction block 47 inside the limiting groove 46. The upper end of the push rod 48 is conical. As the push rod 48 gradually moves upward, it contacts the friction block 47 more tightly, thereby increasing the friction between the push rod 48 and the friction block 47. This allows for adjustment of the rotational resistance between the movable sleeve 18 and the fixed rod 17. By changing the position of the push rod 48, the rotational resistance of the movable sleeve 18 can be maintained within an appropriate range, effectively reducing the probability of the movable sleeve 18 and the connecting plate 19 rotating accidentally due to changes in the patient's position, and further improving the stability of the fixation device.

[0050] like Figure 5 and Figure 6 As shown, a guide assembly is provided inside the mounting box 11. The guide assembly includes a first pin 50 and a second pin 51 fixedly connected to the inner surface of the mounting box 11. A first guide roller 38 is rotatably connected to the outer surface of the first pin 50, and a second guide roller 39 is rotatably connected to the outer surface of the second pin 51. A cavity 44 is opened inside the first guide roller 38 and the second guide roller 39. The first guide roller 38 and the second guide roller 39 are used to guide the extension of the guide tube 13. A moving groove 35 is embedded inside the mounting box 11. A mandrel 36 is slidably connected inside the moving groove 35. An adjusting roller 37 is rotatably connected to the outer surface of the mandrel 36. The outer surface of the adjusting roller 37 is in rotatable contact with the guide tube 13.

[0051] By adopting the above technical solution, the mounting box 11 provides fixed support for pin 50 and pin 51. Pin 50 and pin 51 are used to rotate and support guide roller 38 and guide roller 39, respectively. Guide roller 38 and guide roller 39 rotate and guide the upper and lower ends of the catheter 13, thereby making the catheter 13 move more smoothly inside the mounting box 11. Cavities 44 are opened on the inner side of guide roller 38 and guide roller 39, which can effectively reduce the weight of guide roller 38 and guide roller 39, and thus reduce the weight of the fixing device to a certain extent, which helps to reduce the burden on the patient. The moving groove 35 on the inner surface of the mounting box 11 is used to install and support the mandrel 36. The mandrel 36 is used to rotate and support the adjusting roller 37. The adjusting roller 37, together with the guide roller 38, clamps the upper end of the catheter 13, thereby further improving the smoothness of the catheter 13 during movement and better buffering the tensile force on the catheter 13.

[0052] like Figure 1 , Figure 4 and Figure 6 As shown, a storage component is provided on the lower side of the installation box 11. The storage component includes a bracket 15 fixedly connected to the lower outer surface of the installation box 11. The bracket 15 has a U-shaped structure. A liquid storage bag 14 is placed on the upper outer surface of the bracket 15. The lower end of the conduit 13 extends through to the lower side of the installation box 11 and communicates with the inside of the liquid storage bag 14. A discharge pipe 26 is fixedly connected to the left outer surface of the liquid storage bag 14.

[0053] The bracket 15 has a movable groove 16 on its outer surface. A movable block 40 is slidably connected to the inner side of the movable groove 16. A squeezing plate 25 is fixedly connected to the outer surface of the movable block 40. The squeezing plate 25 is in contact with the upper outer surface of the liquid storage bag 14. A sliding groove 23 is provided on the upper outer surface of the squeezing plate 25. An elastic plate 24 is slidably connected to the inner surface of the sliding groove 23. The elastic plate 24 is arc-shaped. The upper outer surface of the elastic plate 24 is in contact with the lower outer surface of the mounting box 11.

[0054] By adopting the above technical solution, a storage component is provided on the lower side of the installation box 11 for collecting and storing the excreted urine. The installation box 11 supports the fluid collection bag 14 by means of the bracket 15, so that the fluid collection bag 14 can be stably placed on the upper side of the bracket 15, reducing the probability of the fluid collection bag 14 shaking during the patient's movement. The movable groove 16 on the surface of the bracket 15 slides and supports the compression plate 25 through the movable block 40. The upper end of the elastic plate 24 abuts against the lower surface of the installation box 11, and the two ends of the elastic plate 24 are located inside the sliding groove 23 on the surface of the compression plate 25. By applying a certain pressure to the compression plate 25 through the elastic plate 24, the upper end of the fluid collection bag 14 is pressed by the compression plate 25, which can further reduce the probability of the urine inside the fluid collection bag 14 shaking, thereby effectively reducing the risk of the catheter 13 being pulled due to the shaking of the fluid collection bag 14.

[0055] like Figure 2 , Figure 6 and Figure 8 As shown, a clamping assembly is provided on the lower outer surface of the mounting box 11. The clamping assembly includes a fixing sleeve 27 fixedly connected to the lower outer surface of the mounting box 11. The guide tube 13 passes through the fixing sleeve 27 to the lower side of the mounting box 11. A clamping seat 28 is fixedly connected to the outer surface of the fixing sleeve 27. A slot 29 is embedded in the inner side of the clamping seat 28. The slot 29 is annular. A guide seat 31 is fixedly connected to the inner surface of the slot 29. The outer surface of the guide seat 31 is inclined. A contact plate 30 is slidably connected to the upper side of the inner surface of the slot 29.

[0056] The guide seat 31 is slidably connected to the outer surface of the movable seat 32, which is in slidable contact with the outer surface of the contact plate 30. The outer surface of the contact plate 30 away from the movable seat 32 is in contact with the outer surface of the guide tube 13. The mounting plate 34 is fixedly connected to the lower side of the inner surface of the slot 29. The outer surface of the mounting plate 34 is helically connected to the rotating sleeve 33, and the upper end of the rotating sleeve 33 is in rotatable contact with the movable seat 32.

[0057] By adopting the above technical solution, the catheter 13 passes through the fixing sleeve 27 to the outside of the mounting box 11 and connects with the inside of the liquid storage bag 14, so as to facilitate the delivery of urine to the inside of the liquid storage bag 14 through the catheter 13. During operation, it is necessary not only to clamp and fix the lower end of the catheter 13, but also to avoid the probability of the catheter 13 being blocked due to excessive clamping. For this purpose, a clamping component is set. During operation, the operator rotates the rotating sleeve 33. The rotating sleeve 33 is connected to the mounting plate 34 by a screw drive. As the rotating sleeve 33 rotates, it moves synchronously into the slot 29. During the rotation of the rotating sleeve 33, it will... The movable seat 32 is pushed, and the guide seat 31 inside the slot 29 can slide and guide the movable seat 32. During the movement, the movable seat 32 will drive the contact plate 30 to move towards the side of the conduit 13. As several sets of contact plates 30 gradually gather on the outside of the conduit 13, the conduit 13 is clamped by the contact plates 30. By adjusting the position of the contact plates 30, not only can the conduit 13 be clamped well, but the probability of the conduit 13 being blocked due to over-clamping can also be reduced, thereby further improving the ease of operation and stability of the fixed equipment.

[0058] The workflow of the technical solution of this invention is as follows:

[0059] During operation, the installation box 11 is fixed and limited by the cable tie 12 tied to the patient's thigh. Guide roller 1 38 and guide roller 2 39 rotate and guide the upper and lower ends of the catheter 13, respectively. The upper end of the catheter 13 is connected to the balloon catheter, and the lower end of the catheter 13 passes through the lower side of the installation box 11 and communicates with the inside of the reservoir 14. The installation box 11 supports the reservoir 14 by the bracket 15, and the upper end of the reservoir 14 is pressed by the compression plate 25, which can reduce the probability of urine shaking inside the reservoir 14. When the catheter 13 is accidentally pulled, the guide frame 22 will move on one side of the movable sleeve 18 and stretch the traction strip 21. At this time, the fluid wrapped around the surface of the guide frame 22 will be stretched. The catheter 13 will contract and converge towards the movable sleeve 18, thereby releasing the catheter 13 on the surface of the guide frame 22 and buffering and absorbing the pulling force on the catheter 13. When the guide frame 22 moves to the surface of the movable sleeve 18, it will stop moving. The catheter 13 will drive the movable sleeve 18 to rotate through the guide frame 22 and the connecting plate 19. The rotation of the connecting plate 19 and the guide frame 22 can release the catheter 13 wrapped on its surface. The elasticity of the tension spring 43 can buffer and offset the pulling force on the catheter 13, thereby further reducing the discomfort caused to the patient when the catheter 13 is pulled, and thus effectively improving the buffering effect of the pulling force.
