Description

Technical Field

[0001] The invention relates to the field of medical devices, and more specifically to an extracorporeal fixing device for a balloon urinary catheter used for clinical nursing. Background Art

[0002] The 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 balloon's expansion characteristics after the injection of liquid to make it fit tightly to 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 long-term bedridden patients.

[0003] In the prior art, a balloon catheter is usually left in the patient's body and drains urine into an external urine bag. In order to facilitate the patient to carry it with him, the external catheter and the urine bag need to be fixed. For example, a Chinese patent with the authorization announcement number CN111298270B discloses an external fixing device for a balloon catheter for clinical care, which fixes the catheter device to the outside of the body through a strap and a buffer structure, and the buffer structure can minimize the impact of body shaking on the catheter, thereby reducing the pain and discomfort of the user.

[0004] The balloon catheter extracorporeal fixing device in the prior art provides a buffer mechanism between the strap and the shell, which can reduce the shaking of the catheter caused by the patient's position change to a certain extent. However, during clinical use, the catheter extends from the patient's bladder to the urine bag. When the patient turns over or changes his position, the catheter is easily pulled by the bed armrest or bedding. When the catheter is pulled, the external force will be transmitted to the patient's bladder through the catheter, which will not only increase the risk of the catheter damaging the patient's bladder and urethra, but also cause certain inconveniences for the patient to turn over.

[0041] like Figures 1 to 10 As shown, an embodiment of the present invention provides an extracorporeal fixation device for a balloon catheter for clinical nursing, comprising an installation box 11, a fixing rod 17 being fixedly connected to the inner surface of the installation box 11, a buffer component 1 being arranged on the outer side of the fixing rod 17, the buffer component 1 comprising a winding portion and a movable portion, the winding portion comprising a movable sleeve 18 rotatably connected to the outer surface of the fixing rod 17, a connecting plate 19 being fixedly connected to the outer surface of the movable sleeve 18, and the connecting plates 19 are in two groups and are distributed in parallel.

[0042] The movable part includes guide grooves 20 respectively opened on the outer surfaces of the two groups of connecting plates 19, the inner surfaces of the guide grooves 20 are slidably connected with guide frames 22, the outer surface of the guide frame 22 is fixedly connected with a traction bar 21 on the side away from the movable sleeve 18, and the traction bar 21 is fixedly connected to the inner surface of the guide groove 20 at one end away from the guide frame 22, and the guide frame 22 is used to wind the catheter 13.

[0043] The upper end of the catheter 13 is fixedly connected to the bladder ureter, the guide grooves 20 and guide frames 22 are provided in several groups and are distributed in a ring array, the traction strip 21 is made of elastic material, the front end outer surface of the installation 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 scheme, when in use, firstly, the installation box 11 is fixed and limited by tying it around the patient's thigh with a cable tie 12. The Velcro on the surface of the cable tie 12 can realize the quick bundling and installation of the cable tie 12. 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 to perform catheterization on the patient. When the patient turns over or the body moves unexpectedly, it is easy to pull the catheter 13 and the balloon catheter. The balloon catheter will cause damage to the patient's bladder when pulled, and will also greatly increase the patient's pain. For this purpose, a buffer component is provided. The installation box 11 rotatably supports the movable sleeve 18 through the fixed rod 17. The movable sleeve 18 is used to fix and support the two groups of connecting plates 19. The guide groove 20 on the surface of the connecting plate 19 is used to slide and guide the guide frame 22. The traction strip 21 of the elastic material is used to traction and support the guide frame 22. At the same time, part of the catheter 13 is wound around the outside of the guide frame 22 distributed in the annular array, which can reduce the probability of excessive bending of the catheter 13, and at the same time, a certain length of the catheter 13 can be rolled up on 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, and at the same time, the risk of accidental pulling of the catheter 13 can be effectively reduced. When the catheter 13 is accidentally pulled, the guide frame 22 will move on the side of the movable sleeve 18 and stretch the traction strip 21. At this time, the catheter 13 wound on the surface of the guide frame 22 will shrink and gather toward the side of the movable sleeve 18, so that the catheter 13 on the surface of the guide frame 22 can be released to buffer and absorb the pulling force on the catheter 13, thereby effectively reducing the pulling force transmitted to the balloon catheter 13, and further reducing the probability of the balloon catheter 13 causing damage to the patient's bladder and urethra when the patient moves accidentally, thereby effectively ensuring the comfort of the catheterization device during operation.

[0045] like Figure 5 and Figure 7 As shown, a buffer component 2 is provided on the inner side of the installation box 11, and the buffer component 2 includes a slot 41 opened on the inner surface of the installation box 11, and the slot 41 is arc-shaped. A movable plate 42 is fixedly connected to the outer surface of the connecting plate 19 close to the slot 41, and the movable plate 42 extends through the inner side of the slot 41 away from the connecting plate 19 at one end and makes sliding contact with the inner surface of the slot 41, and a tension spring 43 is fixedly connected to the outer surface of the movable plate 42, and the tension spring 43 is fixedly connected to the inner surface of the slot 41 at one end away from the movable plate 42.

[0046] By adopting the above technical scheme, in order to further improve the buffering effect on the catheter 13, a buffer component 2 is set. When one end of the catheter 13 is pulled, the catheter 13 will first drive several groups of guide frames 22 to gather together, and when the guide frame 22 moves to the surface of the movable sleeve 18, it will stop moving. At this time, the catheter 13 wound on the surface of the guide frame 22 cannot be released. At this time, when the external pulling force continues to exist, 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 wound on its surface. During the movement, the connecting plate 19 will drive the movable plate 42 to slide along the inside of the slot 41. During the movement, the movable plate 42 will pull the tension spring 43. The elastic force 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, thereby effectively improving the buffering effect of the pulling force.

[0047] like Figure 4 and Fig.10 As shown, an adjusting component is provided on the inner side of the fixing rod 17, and the adjusting component includes a cavity 49 embedded in the inner side of the fixing rod 17, and a push rod 45 is movably connected to the inner side of the cavity 49. The front end of the push rod 45 passes through the outer side of the installation box 11 and is spirally connected to the installation box 11. The rear side of the outer surface of the push rod 45 is conical, and a through hole 52 is opened on the outer surface of the push rod 45. A push rod 48 is slidably connected to the inner side of the through hole 52.

[0048] A limiting groove 46 is embedded in the inner side of the fixing sleeve 27, and the limiting groove 46 is in a circular ring shape. The upper end of the push rod 48 is conical and penetrates to the inner side of the limiting groove 46. A friction block 47 is fixedly connected to the inner surface of the limiting groove 46. The upper end of the push rod 48 is in rotational 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 in an arc shape, and the lower end of the push rod 48 is in active contact with the outer surface of the push rod 45.

[0049] By adopting the above technical solution, when the buffer component is working, it is necessary to adjust the rotation sensitivity of the connecting plate 19 of the movable sleeve 18 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, a regulating component is set. When it is necessary to increase the rotation resistance of the movable sleeve 18, the operator rotates the push rod 45, and the push rod 45 is connected to the installation box 11 through a spiral transmission. As the push rod 45 rotates, it will slide into the cavity 49. During the movement, the inclined area of ​​the surface of the push rod 45 will contact the outer surface of the lower end of the push rod 48. The push rod 48 is moved upward along the through hole 52 by the movement of the push rod 45, and the push rod 48 will Gradually moving into the limiting groove 46, the upper end of the push rod 48 will contact 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, the push rod 48 will contact the friction block 47 more closely, thereby increasing the friction between the push rod 48 and the friction block 47, and then the rotational resistance between the movable sleeve 18 and the fixed rod 17 can be adjusted. The rotational resistance of the movable sleeve 18 can be maintained within an appropriate range through the position change of the push rod 48, thereby effectively reducing the probability of accidental rotation of the movable sleeve 18 and the connecting plate 19 due to changes in the patient's body position, and then the stability of the fixation device can be further improved.

[0050] like Figure 5 and Figure 6 As shown, a guide assembly is provided on the inner side of the installation box 11, and the guide assembly includes a pin shaft 1 50 and a pin shaft 2 51 which are fixedly connected to the inner surface of the installation box 11, the outer surface of the pin shaft 1 50 is rotatably connected to a guide roller 1 38, and the outer surface of the pin shaft 2 51 is rotatably connected to a guide roller 2 39, and cavities 44 are provided on the inner sides of the guide rollers 1 38 and 39, and the guide rollers 1 38 and 39 are used for guiding the extension of the conduit 13, and a movable groove 35 is embedded on the inner side of the installation box 11, and a core shaft 36 is slidably connected to the inner side of the movable groove 35, and an adjusting roller 37 is rotatably connected to the outer surface of the core shaft 36, and the outer surface of the adjusting roller 37 is in rotational contact with the conduit 13.

[0051] By adopting the above technical scheme, the installation box 11 fixes and supports the pin shaft 1 50 and the pin shaft 2 51, and the pin shaft 1 50 and the pin shaft 2 51 are respectively used to rotationally support the guide roller 1 38 and the guide roller 2 39, and the guide roller 1 38 and the guide roller 2 39 respectively rotationally guide the upper and lower ends of the catheter 13, so that the catheter 13 moves more smoothly inside the installation box 11, and the inner sides of the guide roller 1 38 and the guide roller 2 39 are provided with a cavity 44, which can effectively reduce the dead weight of the guide roller 1 38 and the guide roller 2 39, and thus can reduce the weight of the fixed equipment to a certain extent, which helps to reduce the burden of patients carrying it with them, and the movable groove 35 on the inner surface of the installation box 11 is used to install and support the core shaft 36, and the core shaft 36 is used to rotationally support the adjusting roller 37, and the adjusting roller 37 cooperates with the guide roller 1 38 to clamp the upper end of the catheter 13, so as to further improve the smoothness of the catheter 13 during the movement process, so as to better buffer the pulling force exerted on the catheter 13.

[0052] like Figure 1 , Figure 4 and Figure 6 As shown, a storage component is provided at the lower side of the installation box 11, and the storage component includes a bracket 15 fixedly connected to the outer surface of the lower end of the installation box 11, and the bracket 15 is in a U-shaped structure.

[0053] A movable groove 16 is provided on the outer surface of the bracket 15, and a movable block 40 is slidably connected to the inner side of the movable groove 16. An extrusion plate 25 is fixedly connected to the outer surface of the movable block 40. The extrusion plate 25 is in contact with the outer surface of the upper end of the liquid storage bag 14. A slide groove 23 is provided on the outer surface of the upper end of the extrusion plate 25. An elastic plate 24 is slidably connected to the inner surface of the slide groove 23. The elastic plate 24 is arc-shaped. The outer surface of the upper end of the elastic plate 24 contacts the outer surface of the lower end of the installation box 11.

[0054] By adopting the above technical scheme, a storage component is provided on the lower side of the installation box 11 for collecting and storing discharged urine. The installation box 11 lifts and supports the liquid storage bag 14 through the bracket 15, so that the liquid storage bag 14 can be stably placed on the upper side of the bracket 15, reducing the probability of the liquid storage bag 14 shaking during the patient's activities. The movable groove 16 on the surface of the bracket 15 slidably supports the extrusion plate 25 through the movable block 40. The upper end of the elastic plate 24 is in conflict with the lower surface of the installation box 11, and the two ends of the elastic plate 24 are located inside the slide groove 23 on the surface of the extrusion plate 25. A certain pressure is applied to the extrusion plate 25 through the elastic plate 24, so that the upper end of the liquid storage bag 14 is pressed by the extrusion plate 25, thereby further reducing the probability of urine shaking inside the liquid storage bag 14, and then effectively reducing the risk of the catheter 13 being pulled due to the shaking of the liquid storage bag 14.

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

[0056] The outer surface of the guide seat 31 is slidably connected to a movable seat 32, and the movable seat 32 is in sliding contact with the outer surface of the contact plate 30. The outer surface of the contact plate 30 is in contact with the outer surface of the conduit 13 on the side away from the movable seat 32.

The outer surface of the mounting plate 34 is spirally connected to a rotating sleeve 33, and the upper end of the rotating sleeve 33 is in rotational 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 installation box 11 and is connected to 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. When working, it is necessary not only to clamp and fix the lower end of the catheter 13, but also to avoid the probability of blockage of the catheter 13 caused by excessive clamping. For this purpose, a clamping assembly is provided. When working, the operator rotates the rotating sleeve 33, and the rotating sleeve 33 is connected to the mounting plate 34 through a spiral transmission. As the rotating sleeve 33 rotates, it will synchronously move toward the inside of the card slot 29. During the rotation process, the rotating sleeve 33 will The movable seat 32 is pushed, and the guide seat 31 inside the card slot 29 can slide and guide the movable seat 32. The movable seat 32 will drive the contact plate 30 to move toward the side of the catheter 13 during the movement. As several groups of contact plates 30 gradually gather on the outside of the catheter 13, the catheter 13 is clamped by the contact plate 30. By adjusting the position of the contact plate 30, not only can the catheter 13 be clamped well, but also the probability of excessive clamping of the catheter 13 causing blockage of the catheter 13 can be reduced, thereby further improving the operational convenience and running stability of the fixed equipment.

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

[0059] During operation, the installation box 11 is fixed and limited by tying the cable tie 12 around the patient's thigh, and the guide roller 1 38 and the guide roller 2 39 respectively rotate and guide the upper and lower ends of the catheter 13. 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 is connected to the inside of the liquid storage bag 14. The installation box 11 lifts and supports the liquid storage bag 14 through the bracket 15, and presses the upper end of the liquid storage bag 14 through the extrusion plate 25, which can reduce the probability of urine shaking in the liquid storage bag 14. When the catheter 13 is accidentally pulled, the guide frame 22 will move to one side of the movable sleeve 18 and stretch the traction strip 21. At this time, the The catheter 13 will shrink and gather toward one side of the movable sleeve 18, thereby releasing the catheter 13 on the surface of the guide frame 22 to buffer and absorb 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 the surface thereof, and the elastic force 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, thereby effectively improving the buffering effect of the pulling force.
