Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a tubing positioning and fixing device for peritoneal dialysis. Background Technology

[0002] Peritoneal dialysis utilizes the peritoneum as a semipermeable membrane. Gravity forces prepared dialysate into the patient's peritoneal cavity through a catheter. A concentration gradient exists across the peritoneum; solutes from the side with higher concentrations move to the side with lower concentrations, while water moves from the hypotonic side to the hypertonic side. By continuously replacing the peritoneal dialysis fluid, the goal is to remove metabolic waste products and toxic substances from the body, and to correct water and electrolyte imbalances.

[0003] During peritoneal dialysis treatment, a peritoneal dialysis catheter needs to be inserted into the abdominal cavity. Then, the titanium alloy connector at the outer end of the peritoneal dialysis catheter is sealed to a replaceable external connector. When not performing dialysis, the opening of the external connector is disinfected and sealed with an iodine cap. During dialysis, the iodine cap is removed and discarded, allowing the external connector to be connected to a Y-shaped infusion tubing. The two ends of the Y-shaped infusion tubing are connected to a dialysate bag and a drainage bag, respectively. Then, the dialysate is delivered into the abdominal cavity according to the procedure.

[0004] Currently, medical tape is mostly used to fix peritoneal dialysis catheters to the patient's body surface. However, medical tape is prone to loosening under stress during dialysis, which can cause the dialysis catheter to shake, pull on the patient's wound, and cause discomfort. Furthermore, the adhesiveness of medical tape tends to weaken after prolonged use, requiring regular inspection and replacement to ensure the fixation effect, which is quite inconvenient.

[0005] Therefore, providing a catheter positioning and fixation device for peritoneal dialysis to improve the fixation stability of the peritoneal dialysis catheter and prevent the dialysis catheter from shaking and pulling on the patient's wound, causing patient discomfort, is a technical problem that urgently needs to be solved in this field.

[0036] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0038] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0039] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0041] by Figure 1 For reference, the first direction X is the horizontal direction between the two fixed protrusions 324 of the fixing device 30; the second direction Y is the horizontal direction from the dialysis fixing tube 32 to the fixing disk 31; and the third direction Z is the direction of the connector 33 vertically upward. The first direction X, the second direction Y, and the third direction Z intersect each other perpendicularly.

[0042] In one alternative embodiment, refer to Figures 1-11 The tubing positioning and fixing device 30 for peritoneal dialysis provided in this embodiment includes an abdominal fixation belt 10, which is fixed around the patient's abdomen by a detachable component 20. Specifically, the detachable component 20 includes a detachable A part 21 and a detachable B part 22. The detachable A part 21 is connected to the front of one end of the abdominal fixation belt 10, and the detachable B part 22 is connected to the back of the other end of the abdominal fixation belt 10.

[0043] The abdominal fixation belt 10 has a movable part, and a fixing device 30 is connected to the movable part. The fixing device 30 is used to fix the peritoneal dialysis tubing. The fixing device 30 includes an adhesive fixing disc 31, a dialysis fixing tubing 32 fixed on the adhesive fixing disc 31, and a connector 33 connecting the fixing tubing and the abdominal fixation belt 10. A protective component 40 is fixed on the abdominal fixation belt 10. The protective component 40 is used to fix the peritoneal dialysis tubing.

[0044] Understandably, peritoneal dialysis tubing includes a peritoneal dialysis catheter, a titanium alloy connector, an external connecting tube, and an iodine cap. Patients undergoing peritoneal dialysis have a peritoneal dialysis catheter placed in their abdominal cavity. The external end of the peritoneal dialysis catheter is connected to a titanium alloy connector, and the other end of the titanium alloy connector is sealed to a replaceable external connecting tube. The opening of the external connecting tube is disinfected and sealed with an iodine cap when dialysis is not being performed.

[0045] The fixation device 30 has a channel for the peritoneal dialysis catheter to pass through. The diameter of the channel of the adhesive fixation disc 31 is larger than the diameter of the titanium alloy connector at the external end of the peritoneal dialysis catheter, and the diameter of the dialysis fixation tube 32 is larger than the diameter of the peritoneal dialysis catheter. The adhesive fixation disc 31 and the dialysis fixation tube 32 are used to position and restrict the movement of the peritoneal dialysis catheter, preventing displacement. Specifically, the adhesive fixation disc 31 is a circular, adhesive disc with a dedicated channel in the center for the peritoneal dialysis catheter to pass through. The adhesive fixation disc 31 can be firmly adhered to the skin, fixing the peritoneal dialysis catheter in the center of the adhesive fixation disc 31. The adhesive fixation disc 31 has a relatively large contact area with the skin, dispersing the pressure on the skin during adhesion and effectively reducing the risk of skin damage. The adhesive fixation disc 31 can be made of medical-grade silicone material to protect the skin.

[0046] When using the peritoneal dialysis tubing positioning and fixing device 30 of this embodiment, the adhesive fixing disc 31 is fixed to the patient's abdomen, the dialysis fixing tube 32 is wrapped around the peritoneal dialysis tube and fixed to the adhesive fixing disc 31, the movable part of the abdominal fixing band 10 passes through the dialysis fixing tube 32 in the second direction Y, and the connector 33 passes through the movable part opened on the abdominal fixing band 10 in the third direction Z; the movable range of the abdominal fixing band 10 is limited within the movable part opened on the abdominal fixing band 10 by the connector 33; the connection position between the detachable A part 21 and the detachable B part 22 is adjusted according to the size of the patient's abdominal waist circumference, so that the abdominal fixing band 10 is tightly wrapped around and fixed to the patient's abdomen, preventing the fixing device 30 from falling off, improving the stability and safety of the fixing device 30, and reducing the possibility of accidental displacement of the dialysis tube; the peritoneal dialysis tubing (including the peritoneal dialysis tube, titanium alloy connector, external connecting tube and iodine cap) located outside the fixing device 30 is placed on the abdominal fixing band 10 and protected by the protective component 40.

[0047] It should be noted that the adhesive fixing disc 31 cannot pass through the movable part on the abdominal fixation belt 10, while the dialysis fixing tube 32 can pass through the movable part on the abdominal fixation belt 10. The connection position between the detachable A part 21 and the detachable B part 22 is adjusted according to the patient's abdominal circumference to ensure the abdominal fixation belt 10 is tightly wrapped around and fixed to the patient's abdomen. Adjustment is required when the abdominal fixation belt 10 is wrapped around and fixed to the patient's abdomen (if the abdominal fixation belt 10 is too loose, it may not provide adequate fixation; if it is too tight, it may affect the patient's breathing and blood circulation). During adjustment, the abdominal fixation belt 10 moves, and the movable part moves accordingly, preventing the fixing device 30 fixed to the abdominal fixation belt 10 from being pulled by the movement of the abdominal fixation belt 10. The abdominal fixation belt 10 provides a relatively wide fixation range, securing the peritoneal dialysis tubing to the abdominal fixation belt 10 and reducing significant shaking caused by the peritoneal dialysis tubing's movement. The protective component 40 wraps the peritoneal dialysis tubing around the abdominal fixation strap 10 to prevent accidental pulling on the peritoneal dialysis tubing and the intra-abdominal peritoneal dialysis catheter. During use, the tubing positioning and fixation device 30 used for peritoneal dialysis should be disinfected regularly with a disinfectant spray to prevent bacterial infection at the peritoneal dialysis catheter and the catheter insertion opening in the patient's abdomen.

[0048] In one alternative embodiment, refer to Figures 1-7 The movable part includes a first movable groove 11 and a second movable groove 12, which intersect perpendicularly and pass through the abdominal fixing belt 10.

[0049] Understandably, the first movable groove 11 passes through the abdominal fixation belt 10 along the second direction Y, and the second movable groove 12 passes through the abdominal fixation belt 10 and the first movable groove 11 along the third direction Z. The height of the first movable groove 11 along the third direction Z is greater than the diameter of the dialysis fixation tube 32, and the width of the second movable groove 12 along the second direction Y is greater than the diameter of the connecting shaft 331. The first movable groove 11 of the abdominal fixation belt 10 passes through the dialysis fixation tube 32 along the second direction Y. In the third direction Z, the connector 33 passes through the second movable groove 12 opened on the abdominal fixation belt 10 and connects to the dialysis fixation tube 32. When adjusting the abdominal fixation belt 10, moving the abdominal fixation belt 10 does not move the fixation device 30, preventing pulling on the wound.

[0050] In one alternative embodiment, refer to Figures 1-4 , Figures 8-11The dialysis fixation tube 32 is located within the first moving groove 11. The dialysis fixation tube 32 includes a first fixed half-tube 321 and a second fixed half-tube 322. A fixing groove 323 is formed on the long side wall of the first fixed half-tube 321, and a fixing protrusion 324 adapted to the fixing groove 323 is fixed on the long side wall of the second fixed half-tube 322. The adhesive fixing disc 31 includes a disc body 311 and an insertion protrusion 312 fixed on the disc body 311. Insertion grooves 325 adapted to the insertion protrusion 312 are respectively formed on the semi-annular side walls of the first fixed half-tube 321 and the second fixed half-tube 322. The connecting member 33 includes a connecting shaft 331 and a limiting member 332. One connecting shaft 331 passes through a second moving groove 12 and is connected to the first fixed half-tube 321 and the limiting member 332 at both ends. The other connecting shaft 331 passes through another second moving groove 12 and is connected to the second fixed half-tube 322 and the limiting member 332 at both ends.

[0051] Understandably, the fixing protrusion 324 of the second fixed half-tube 322 is aligned with the fixing groove 323 of the first fixed half-tube 321 to fix the peritoneal dialysis catheter inside the dialysis fixing tube 32; then, the insertion groove 325 of the dialysis fixing tube 32 is connected to the insertion protrusion 312 on the disc body 311, connecting the dialysis fixing tube 32 to the adhesive fixing disc 31, thus restricting the circumferential movement of the peritoneal dialysis catheter. The connecting shaft 331 of the connector 33 can move within the second moving groove 12, and the diameter of the limiting member 332 is greater than the width of the second moving groove 12 along the second direction Y, preventing the connecting shaft 331 from disengaging from the second moving groove 12; the connector 33 restricts the movement range of the abdominal fixation belt 10 within the first groove opened on the abdominal fixation belt 10, preventing the peritoneal dialysis catheter from being pulled when wearing the abdominal fixation belt 10.

[0052] It should be noted that the insertion protrusion 312 and the insertion groove 325 may be provided with structures or textures to increase connection stability and prevent the dialysis fixation tube 32 from detaching from the adhesive fixation disc 31.

[0053] In one alternative embodiment, refer to Figures 1-4 , Figures 8-11 The dialysis fixation tube 32 also includes a first anti-slip layer 326 and a second anti-slip layer 327. The first anti-slip layer 326 is connected to the inner wall of the first fixed half tube 321, and the second anti-slip layer 327 is connected to the inner wall of the second fixed half tube 322. A connecting shaft 331 passes through a second moving groove 12 and the first fixed half tube 321, and its two ends are respectively connected to the first anti-slip layer 326 and the limiting member 332. Another connecting shaft 331 passes through another second moving groove 12 and the second fixed half tube 322, and its two ends are respectively connected to the second anti-slip layer 327 and the limiting member 332.

[0054] Understandably, to improve the stability of the fixation device 30 and prevent the peritoneal dialysis catheter from being pulled, a first anti-slip layer 326 is placed on the inner wall of the first fixation half-tube 321, and a second anti-slip layer 327 is placed on the inner wall of the second fixation half-tube 322; the fixing protrusion 324 of the second fixation half-tube 322 is aligned with the fixing groove 323 of the first fixation half-tube 321 to fix the peritoneal dialysis catheter inside the dialysis fixation tube 32; then the insertion groove 325 of the dialysis fixation tube 32 is connected to the insertion protrusion 312 on the disc body 311 to fix the dialysis fixation tube 322. 2. Connected to the adhesive fixing disc 31, it restricts the circumferential movement of the peritoneal dialysis catheter. At this time, there is a gap between the wall of the peritoneal dialysis catheter and the first anti-slip layer 326 and the second anti-slip layer 327. By rotating the connector 33, the distance between the connecting shaft 331 and the wall of the peritoneal dialysis catheter is adjusted so that the first anti-slip layer 326 abuts against the wall of the peritoneal dialysis catheter and the second anti-slip layer 327 abuts against the wall of the peritoneal dialysis catheter, so that the peritoneal dialysis catheter is tightly connected to the dialysis fixing tube 32, thereby improving the stability of the fixing device 30 and preventing the peritoneal dialysis catheter from being pulled or dragged.

[0055] It should be noted that the connecting shaft 331 passes through the first fixed half-tube 321 and the second fixed half-tube 322. The through holes on the first fixed half-tube 321 and the second fixed half-tube 322 can be threadedly connected to the connecting shaft 331. By rotating the connecting piece 33, the distance between the connecting shaft 331 and the wall of the peritoneal dialysis catheter can be adjusted so that the first anti-slip layer 326 abuts against the wall of the peritoneal dialysis catheter and the second anti-slip layer 327 abuts against the wall of the peritoneal dialysis catheter, so that the peritoneal dialysis catheter is tightly connected to the dialysis fixation tube 32, thereby improving the stability of the fixation device 30 and preventing the peritoneal dialysis catheter from being pulled or tugged.

[0056] In one alternative embodiment, refer to Figures 1-7 The protective component 40 includes a first protective member 41, a second protective member 42, and a third protective member 43. One side of the first protective member 41 is fixed to the front of the abdominal fixation belt 10, and the other side of the first protective member 41 is fixed with a detachable B part 22. The front of the abdominal fixation belt 10 corresponding to the first protective member 41 is fixed with a detachable A part 21, and the detachable A part 21 is detachably connected to the detachable B part 22 on the first protective member 41.

[0057] One side of the second protective member 42 is fixed to the front of the abdominal fixation belt 10, and the other side of the second protective member 42 is fixed with a detachable B part 22. The front of the abdominal fixation belt 10 corresponding to the second protective member 42 is fixed with a detachable A part 21, and the detachable A part 21 is detachably connected to the detachable B part 22 on the second protective member 42.

[0058] One side of the third protective member 43 is fixed to the front of the abdominal fixation belt 10, and the other side of the third protective member 43 is fixed with a detachable B part 22. The front of the abdominal fixation belt 10 corresponding to the third protective member 43 is fixed with a detachable A part 21, and the detachable A part 21 is detachably connected to the detachable B part 22 on the third protective member 43.

[0059] Understandably, after the fixation device 30 and abdominal fixation strap 10 are put on, the titanium alloy connector outside the fixation device 30 is placed at the first protective member 41, and the detachable B part 22 of the first protective member 41 is connected to the corresponding detachable A part 21 of the first protective member 41, thus fixing the titanium alloy connector within the space enclosed by the first protective member 41 and the abdominal fixation strap 10. The iodine cap outside the fixation device 30 is placed at the second protective member 42, and the detachable B part 22 of the second protective member 42 is connected to the corresponding detachable A part 21 of the second protective member 42, thus fixing the iodine cap within the space enclosed by the second protective member 42 and the abdominal fixation strap 10. The detachable B part 22 of the third protective member 43 is connected to the corresponding detachable A part 21 of the third protective member 43, thus fixing part of the peritoneal dialysis tubing and external connecting tube within the space enclosed by the third protective member 43 and the abdominal fixation strap 10. This prevents accidental pulling on the peritoneal dialysis tubing outside the fixation device 30. To improve the stability of the peritoneal dialysis catheter and prevent it from shaking and pulling on the patient's wound, causing discomfort.

[0060] It should be noted that the detachable A part 21 and detachable B part 22 are preferably detachable Velcro. The length and position of the first protective member 41, the second protective member 42 and the third protective member 43 are set as needed. By compressing and fixing the peritoneal dialysis tubing to a suitable position on the abdominal fixation belt 10, the significant shaking of the peritoneal dialysis tubing caused by body movement can be reduced.

[0061] In one alternative embodiment, refer to Figures 1-11 The abdominal fixation strap 10 includes an inner lining layer 13.

[0062] Understandably, the skin-friendly inner lining 13 on the reverse side of the abdominal fixation strap 10 will not cause excessive friction to the skin and will improve the patient's wearing comfort.

[0063] Use of the peritoneal dialysis tubing positioning and fixing device 30: An adhesive fixing disc 31 is fixed to the patient's abdomen; a first anti-slip layer 326 is placed on the inner wall of the first fixing half-tube 321, and a second anti-slip layer 327 is placed on the inner wall of the second fixing half-tube 322; the fixing protrusion 324 of the second fixing half-tube 322 is aligned with the fixing groove 323 of the first fixing half-tube 321, fixing the peritoneal dialysis tubing inside the dialysis fixing tube 32; then, the insertion groove 325 of the dialysis fixing tube 32 is connected to the insertion protrusion 312 on the disc body 311, connecting the dialysis fixing tube 32 to the adhesive fixing disc 31, restricting the circumferential movement of the peritoneal dialysis tubing.

[0064] Wearing the abdominal fixation belt 10, the first moving groove 11 of the abdominal fixation belt 10 passes through the dialysis fixation tube 32 along the second direction Y. In the third direction Z, the connector 33 passes through the second moving groove 12 opened on the abdominal fixation belt 10 and connects with the dialysis fixation tube 32. At this time, there is a gap between the tube wall of the peritoneal dialysis tube and the first anti-slip layer 326 and the second anti-slip layer 327.
