Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a fixation device for peritoneal dialysis catheter replacement. Background Technology

[0002] Peritoneal dialysis is currently one of the main renal replacement therapies for end-stage renal disease. To prevent related infectious complications, the external catheter must be replaced every six months. The current method for replacing the external catheter is as follows: A sterile drape is laid, and the external catheter is clamped with hemostatic forceps (or blue clips) padded with gauze. After separating the external catheter and the titanium connector, the titanium connector is quickly immersed in a 0.5% povidone-iodine solution for about ten minutes. During this process, the patient or family member needs to assist by holding the povidone-iodine solution bottle. After immersion, the titanium connector is wrapped with sterile gauze and connected to the new external catheter, and a new povidone-iodine cap is replaced. The tubing is then properly secured. However, holding the povidone-iodine solution bottle for ten minutes can easily lead to fatigue for the patient or family member, restricting their movement and resulting in a poor patient experience. Furthermore, because the catheter (titanium connector) is directly inserted into the povidone-iodine solution bottle without securing it, slight carelessness can cause some of the titanium connector to leak out of the disinfectant solution, leading to inadequate disinfection and contamination.

Detailed Implementation

[0041] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0042] Example 1

[0043] A specific embodiment of this utility model, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a fixing device for changing short catheters in peritoneal dialysis is disclosed, including a base 1, a pressure cap 2, a first connecting strap 3, and a second connecting strap 4. The base 1 and the pressure cap 2 are detachably connected. One end of the first connecting strap 3 is connected to the base 1, and the other end is provided with a first Velcro female surface 31. One end of the second connecting strap 4 is connected to the base 1, and the other end is provided with a first Velcro female surface 41. The base 1 is provided with a first receiving cavity 11, and the top of the base 1 is provided with a first connecting hole 12. The pressure cap 2 and the top of the base 1 form a second receiving cavity 21, and the pressure cap 2 is provided with a stepped groove 22.

[0044] Compared with the prior art, the fixing device for peritoneal dialysis catheter replacement operation provided in this embodiment has a first receiving cavity 11 on the base 1, and a second receiving cavity 21 formed by the cap 2 and the top of the base 1. When replacing the external short tube, the body of the disinfectant bottle is placed in the first receiving cavity 11, and the neck of the disinfectant bottle extends into the second receiving cavity 21 through the first connecting hole 12 of the base 1. The cap 2 contacts the bottle mouth of the disinfectant bottle, the catheter is locked in the stepped groove 22, the titanium connector is immersed in the disinfectant, and the first connecting strap 3 and the second connecting strap 4 are connected by Velcro. The base 1 is worn on the user's waist, eliminating the need for the user or their family to hold the disinfectant bottle for a long time. The disinfectant bottle can move with the user, the catheter is fixed, and the titanium connector can be fully immersed.

[0045] To reduce the storage space occupied by the fixing device before use, the base 1 is foldable; in other words, the base 1 can be folded into a roughly flat structure before use. Specifically, as shown... Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the base 1 includes a first support plate 13, a second support plate 14, and a third support plate 15. Before folding, the first support plate 13, the second support plate 14, and the third support plate 15 unfold into a flat plate. After folding, the first support plate 13, the second support plate 14, and the third support plate 15 form a U-shaped structure, that is, the first support plate 13 and the third support plate 15 are parallel, and the second support plate 14 is perpendicular to the first support plate 13. The first supporting plate 13, the second support plate 14, and the third support plate 15 form a first receiving cavity 11. It should be noted that the base 1 is integrally formed.

[0046] To achieve the folding of base 1, as follows: Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the base 1 also includes a first hinge 16 and a second hinge 17. The first hinge 16 connects the edge of the first support plate 13 and the edge of the second support plate 14, and the second hinge 17 connects the edge of the second support plate 14 and the edge of the third support plate 15. Preferably, there are two of each of the first hinge 16 and the second hinge 17. The first hinge 16 and the second hinge 17 are symmetrically arranged.

[0047] Combination Figure 6 , Figure 7 and Figure 8As shown, the first support plate 13 is provided with the first connecting hole 12 mentioned above, and the second support plate 14 is provided with the first slot 141 and the second slot 142. The end of the first connecting strap 3 without the first Velcro female side 31 is connected to the first slot 141, and the end of the second connecting strap 4 without the first Velcro female side 41 is connected to the second slot 142.

[0048] Similarly, cap 2 can also be folded, combined with Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10 As shown, the pressure cap 2 includes a pressure plate 23, a connecting plate 24, and a third hinge 25. The pressure plate 23 is connected to the connecting plate 24 via the third hinge 25. Specifically, the third hinge 25 connects the edge of the pressure plate 23 and the edge of the connecting plate 24. It should be noted that the pressure cap 2 is integrally formed. Before use, the pressure plate 23 and the connecting plate 24 are folded into a flat plate, that is, the pressure plate 23 and the connecting plate 24 are parallel. When in use, the pressure cap 2 unfolds into an L-shaped structure, with the pressure plate 23 parallel to the first support plate 13 and the connecting plate 24 connected to the second support plate 14.

[0049] It should be noted that a movable hinge is a thin, one-piece molded plastic structure, typically made of high-fatigue-resistant materials such as PP (Polypropylene). It achieves opening and closing through the elastic deformation of the material (rather than mechanical parts), maintaining its function even after repeated bending. A common structure in packaging such as soy sauce bottles, detergent bottle caps, and milk powder cans, its core feature is achieving repeated opening and closing through the inherent flexibility of the plastic material, rather than relying on traditional mechanical hinges. This structure is a mature, existing technology and will not be elaborated upon further here.

[0050] To secure the catheter, the clamping plate 23 is provided with the aforementioned stepped slot 22. Considering that the outer diameter of the titanium connector is larger than the diameter of the catheter, the stepped slot 22 is designed as a stepped groove. The larger groove (i.e., the wider groove) allows the titanium connector to pass through, while the smaller groove (i.e., the narrower groove) is used to hold the catheter in place. Understandably, the width of the smaller groove is less than the diameter of the catheter. Users must wear disposable sterile gloves when changing the external short tubing to avoid contaminating the sterilized parts.

[0051] In order to adjust the distance between the pressure plate 23 and the first support plate 13 to accommodate disinfectant bottles of different sizes and specifications, combined with Figure 3 , Figure 7 , Figure 10 , Figure 11 and Figure 12As shown, the fixing device also includes an elastic limiting member 5. A first connecting post 143 is provided on the second support plate 14, and a second connecting hole 144 is provided along the axis of the first connecting post 143. A plurality of third connecting holes 241 are provided on the connecting plate 24, and the plurality of third connecting holes 241 are evenly arranged along the height direction of the connecting plate 24. The outer diameter of the first connecting post 143 is equal to the diameter of the third connecting hole 241. A second connecting post 242 is provided on one side of the third connecting hole 241. One end of the elastic limiting member 5 is provided with a limiting part 51, and a protrusion 52 connected to the second connecting hole 144 is provided on one side of the limiting part 51. The outer contour of the limiting part 51 is larger than the diameter of the third connecting hole 241. The other end of the elastic limiting member 5 is provided with a fourth connecting hole 53 connected to the second connecting post 242. The elastic limiting member 5 is fixedly connected to the second connecting post 242. If it is bonded, the protrusion 52 at the other end is pressed into the second connecting hole 144, and the limiting part 51 limits the connection plate 24.

[0052] Combination Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, the fixing device also includes a first connecting member 6. When the base 1 unfolds into a C-shaped structure, the upper end of the first connecting member 6 is connected to the first support plate 13, and the lower end of the first connecting member 6 is connected to the third support plate 15. Specifically, both ends of the first connecting member 6 are provided with a second hook-and-loop fastener female surface 61, and both the first support plate 13 and the third support plate 15 are provided with a second hook-and-loop fastener female surface 18. Both ends of the first connecting member 6 are connected to the second hook-and-loop fastener surface 18. When connecting the first connecting member 6, it is necessary to tighten the first connecting member 6. Since the first support plate 13 is stuck on the neck of the disinfectant bottle, and the third support plate 15 is in contact with the bottom of the disinfectant bottle, tightening the first connecting member 6 allows the first support plate 13 to move closer to the third support plate 15. Preferably, there are two first connecting members 6, which are symmetrically arranged about the disinfectant bottle.

[0053] Combination Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 9 and Figure 10As shown, the fixing device also includes a second connecting member 7. When the pressure cap 2 is unfolded into an L-shaped structure, the upper end of the second connecting member 7 is connected to the pressure plate 23, and the lower end of the second connecting member 7 is connected to the first support plate 13. Specifically, both ends of the second connecting member 7 are provided with a third hook and loop fastener female surface 71, and both the first support plate 13 and the pressure plate 23 are provided with a third hook and loop fastener female surface 19. The two ends of the second connecting member 7 are connected to the third hook and loop fastener surface 19. When connecting the second connecting member 7, it is necessary to tighten the second connecting member 7. Since the pressure plate 23 presses on the mouth of the disinfectant bottle, tightening the second connecting member 7 allows the pressure plate 23 to move closer to the first support plate 13. Preferably, there are two second connecting members 7, and the two second connecting members 7 are symmetrically arranged about the stepped slot 22.

[0054] It is worth noting that both the first connector 6 and the second connector 7 are elastic connectors, and their ends are provided with Velcro, similar to the structure of a restraint strap. Under the elastic retraction of the first connector 6 and the second connector 7, the first support plate 13 moves closer to the third support plate 15, and the pressure plate 23 moves closer to the first support plate 13.

[0055] Example 2

[0056] Another specific embodiment of this utility model is as follows: Figure 13 As shown, a fixing device for changing short catheters in peritoneal dialysis is disclosed. Considering that the disinfectant solution may easily spill out if tilted or bumped during the handling of the iodine solution bottle, an elastic fixing plug 8 is added based on Example 1. The elastic fixing plug 8 is located at the mouth of the disinfectant solution bottle, and a through hole 81 is provided along the axial direction of the elastic fixing plug 8. The titanium connector passes through the through hole 81 of the elastic fixing plug 8 and enters the disinfectant solution bottle for immersion, and the elasticity of the elastic fixing plug 8 is used to further fix the catheter.

[0057] In this embodiment, the fixing device also includes an elastic fixing plug 8, which is located at the mouth of the disinfectant bottle. It can fix the tubing and reduce the risk of disinfectant overflow from the bottle, so that the titanium connector can be fully immersed in the disinfectant for disinfection.

[0058] It should be noted that the elastic retainer 8 is individually packaged. Users need to wear disposable sterile gloves when changing the external short tube to avoid contaminating the sterilized part.

[0059] Example 3

[0060] Another specific embodiment of this utility model is as follows: Figure 14As shown, a fixation device for peritoneal dialysis catheter replacement is disclosed. Considering that the fixation device will be worn around the user's waist, in order to improve wearing comfort, a sponge layer 9 is provided on the outer side of the second support plate 14, based on Embodiment 1. In this embodiment, the sponge layer 9 is provided on the outer side of the second support plate 14, making it more comfortable for the user to wear the base 1, and also roughly adapting to the curve of the user's waist.

[0061] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
