Description

Technical Field

[0001] This utility model relates to the field of peritoneal dialysis catheter fixation box. Background Technology

[0002] Peritoneal dialysis uses the body's own peritoneum as a dialysis membrane. The peritoneum is a semi-permeable membrane covering the inner surface of the abdominal cavity and has a certain degree of permeability. By infusing dialysis fluid into the abdominal cavity, metabolic waste and excess water in the blood pass through the peritoneum into the dialysis fluid according to the concentration gradient. Some beneficial substances in the dialysis fluid, such as glucose and electrolytes, can also enter the blood, thereby achieving the purpose of removing metabolic waste from the body and correcting water, electrolyte and acid-base imbalances.

[0003] After the surgery, the portion of the dialysis catheter outside the body needs to be secured to prevent it from being pulled out or shifted due to external force, which could cause injury to the patient. Traditionally, this is done by directly wrapping the exposed portion of the dialysis catheter with gauze or sterile dressings. However, the adhesiveness of gauze or sterile dressings decreases over time, and the fixation is not very secure. Therefore, under external force, the tape or dressing may loosen at any time, leading to contamination of the dialysis catheter. Furthermore, simply wrapping with gauze is not very effective; patients can easily bump into the dialysis catheter during significant movements, causing it to shift or become misaligned, posing a danger. More seriously, it can tear the incision, causing secondary injury, increasing the risk of infection, and necessitating re-insertion of the catheter, further increasing the risk of infection. Secondly, displacement of the dialysis catheter can easily induce infection. Utility Model Content

[0035] Reference Appendix Figure 1 To be continued Figure 4 As shown, a peritoneal dialysis catheter fixation box according to a preferred embodiment of the present invention is illustrated. The peritoneal dialysis catheter fixation box 1 is used after peritoneal dialysis to fix the dialysis catheter 90. The peritoneal dialysis catheter fixation box 1 can limit and fix the portion of the dialysis catheter 90 located on the outside of the patient's body, ensuring that the dialysis catheter 90 and the patient's body are relatively stable, preventing the dialysis catheter 90 from being pulled out quickly due to external force, causing misalignment or movement, and thus causing injury to the patient. Those skilled in the art should understand that the peritoneal dialysis catheter fixation box 1 is not only suitable for peritoneal dialysis, but can also be used after other surgeries to fix surgical instruments such as indwelling catheters.

[0036] For ease of explanation, in this embodiment, the end of the peritoneal dialysis catheter fixation box 1 connected to the dialysis catheter 90 is designated as the front end of the peritoneal dialysis catheter fixation box 1, and the end opposite to the front end of the peritoneal dialysis catheter fixation box 1 is designated as the rear end of the peritoneal dialysis catheter fixation box 1. The end of the dialysis catheter 90 remaining inside the patient's body is defined as its inner end, and the end of the dialysis catheter 90 outside the patient's body is defined as its outer end.

[0037] Figure 1 This is a schematic diagram of the overall structure of the peritoneal dialysis catheter fixation box 1 according to the first preferred embodiment of the present invention. In this embodiment, the peritoneal dialysis catheter fixation box 1 includes a fixing component 10, a storage component 20, and a limiting component 30. The storage component 20 is openably installed on the fixing component 10. The fixing component 10 is adapted to be fixed to the skin surface of a patient. The limiting component 30 is disposed on the fixing component 10 and the storage component 20. The dialysis catheter 90 is adapted to be fixed by the limiting component 30 to prevent the dialysis catheter 90 from being pulled out quickly due to external force, causing misalignment or movement, and thus causing damage to the patient.

[0038] The fixing component 10 includes a main body layer 11, an adhesive layer 12, and a protective layer 13. The adhesive layer 12 is disposed on the main body layer 11, and the protective layer 13 is peelably disposed below the adhesive layer 12. That is, the protective layer 13 peelably covers the underside of the main body layer 11 through the adhesive layer 12. In other words, the main body layer 11, the adhesive layer 12, and the protective layer 13 are arranged and bonded together from top to bottom.

[0039] When the peritoneal dialysis catheter fixation box 1 is not in use, the main body layer 11, the adhesive layer 12, and the protective layer 13 overlap and adhere to each other to form a thin sheet. When the peritoneal dialysis catheter fixation box 1 is in use, the protective layer 13 is peeled off from the adhesive layer 12, which is adapted to adhere to the patient's skin surface for fixation. The main body layer 11, adhesive layer 12, and protective layer 13 are each a thin sheet structure to reduce the volume and area occupied by the fixation assembly 10, increasing patient comfort and convenience during use.

[0040] Furthermore, the adhesive layer 12 can be repeatedly applied and can be placed in a suitable location according to the patient's needs without affecting their daily activities. In other words, the adhesive layer 12 is not made of disposable materials and can be repeatedly peeled off and applied to the patient's body surface. Additionally, the main body layer 11 is preferably made of a flexible and elastic material to increase the comfort of the peritoneal dialysis catheter fixation box 1 during use and to prevent skin infections and other complications for the patient.

[0041] The fixing component 10 further has an installation channel 14 that extends downward from the surface of the main body layer 11 to penetrate the adhesive layer 12 and the protective layer 13. That is, the main body layer 11, the adhesive layer 12, and the protective layer 13 each form a portion of the installation channel 14. The installation channel 14 is in a closed state under normal conditions. When it is necessary to fix the dialysis catheter 90 to the peritoneal dialysis catheter fixing box 1, the installation channel 14 is adapted to be opened by the limiting component 30.

[0042] The limiting component 30 includes a first limiting component 31 and a second limiting component 32, wherein the first limiting component 31 is disposed on the main body layer 11 of the fixing component 10. Specifically, the first limiting component 31 is adapted to open the installation channel 14, and the second limiting component 32 is disposed on the storage component 20. The dialysis tube 90 is adapted to be fixed in the storage component 20 by the first limiting component 31 and the second limiting component 32.

[0043] The first limiting component 31 includes a first extension 311, a second extension 312, and a holding unit 313. The first extension 311 and the second extension 312 are integrally connected to the holding unit 313. In other words, the first extension 311 and the second extension 312 extend rearward from the holding unit 313 at a predetermined angle. The first extension 311 and the second extension 312 are adapted to be squeezed, thereby opening the holding unit 313 and driving the installation channel 14 to open, so that the portion of the dialysis tube 90 extending from the patient's body is held and fixed by the holding unit 313. The angle between the first extension 311 and the second extension 312 is set to 30° to 90°, preferably set to 60°, so that the user can use minimal force to squeeze the first extension 311 and the second extension 312, thereby opening the holding unit 313 and driving the installation channel 14 to open.

[0044] The first limiting component 31 further has a holding cavity 314 and a holding opening 315. The holding cavity 314 extends downward from the top of the holding unit 313 to penetrate the holding unit 313. The dialysis tube 90 is adapted to be placed in the holding cavity 314. The holding opening 315 is provided in the holding unit 313 to communicate with the mounting channel 14 of the fixing component 10. That is, the first extension 311 and the second extension 312 are adapted to be squeezed to open the holding opening 315 and the mounting channel 14. The dialysis tube 90 is adapted to be placed into the holding cavity 314 through the holding opening 315 and the mounting channel 14. Then, the first extension 311 and the second extension 312 are released, and the holding opening 315 and the mounting channel 14 close again, so that the holding unit 313 can hold the dialysis tube 90 around its periphery to achieve a fixing effect. Therefore, the end of the dialysis tube 90 will not come into contact with the peritoneal dialysis tube fixing box 1, thus avoiding additional contamination of the dialysis tube 90 and affecting the user.

[0045] The storage assembly 20 includes a storage shell 21, a storage cavity 22, and an outlet channel 23. The storage cavity 22 is located inside the storage shell 21 to store the dialysis tube 90. The storage shell 21 includes a peripheral shell 211 and a top shell 212, which are integrally connected. The fixing assembly 10 is operably installed below the storage shell 21, thereby surrounding the peripheral shell 211 and the top shell 212 to fix the dialysis tube 90 inside the storage cavity 22. The outlet channel 23 is disposed on the peripheral shell 211 of the storage shell 21. Furthermore, the outlet channel 23 extends outward from the inside of the peripheral shell 211 of the storage shell 21 to penetrate the peripheral shell 211. The outlet channel 23 communicates with the storage cavity 22, and the outermost end of the dialysis tube 90 is adapted to extend out of the outlet channel 23 for corresponding dialysis operations.

[0046] The second limiting component 32 includes a rotating unit 321 and a limiting groove 322. The rotating unit 321 is rotatably disposed on the top housing 212 of the receiving component 20. The limiting groove 322 is located within the receiving cavity 22 and surrounds the rotating unit 321. The dialysis tube 90 is adapted to be wound around the rotating unit 321 and fixed within the limiting groove 322. Finally, the outermost end of the dialysis tube 90 extends to the outlet channel 23 and protrudes out. The peritoneal dialysis tube fixing box 1 fixes the dialysis tube 90 without affecting the normal introduction and outflow of dialysis fluid, and can still realize basic peritoneal dialysis operations.

[0047] It is worth mentioning that when the dialysis tube 90 extends from the patient's body, the first extension 311 and the second extension 312 are squeezed to open the holding opening 315 and the mounting channel 14, allowing the dialysis tube 90 to be placed into the holding cavity 314 through the holding opening 315 and the mounting channel 14. Then, the first extension 311 and the second extension 312 are released, and the holding opening 315 and the mounting channel 14 close again, allowing the holding unit 313 to hold the dialysis tube 90 around its periphery for a fixed effect. Then, the protective layer 13 is peeled off from the adhesive layer 12, and the adhesive layer 12 is adhered to the patient's skin surface. Then, the dialysis tube 90 is wound around the rotating unit 321 and fixed within the limiting groove 322, with the outermost end of the dialysis tube 90 extending to the outlet channel 23 and protruding to perform the corresponding dialysis operation when necessary. Finally, the storage housing 21 is closed, so that the storage housing 21 fits into the fixing component 10, thus completing the installation of the peritoneal dialysis tube fixing box 1.

[0048] In summary, the peritoneal dialysis catheter fixation box 1 can fix the part of the dialysis catheter 90 located on the outside of the patient's body, ensuring that the dialysis catheter 90 and the patient's body are relatively stable, and preventing the dialysis catheter 90 from being pulled out quickly due to external force, causing misalignment or movement, and thus causing damage to the patient.

[0049] As attached Figures 5 to 6 The second preferred embodiment of the present invention provides a peritoneal dialysis catheter fixation box 1A. Figure 5 This is a schematic diagram of the overall structure of the peritoneal dialysis catheter fixation box 1A according to a second embodiment of the present invention. The peritoneal dialysis catheter fixation box 1A in this embodiment is a variation of the first embodiment described above.

[0050] Compared to the first embodiment described above, in this embodiment, similarly, the peritoneal dialysis catheter fixation box 1A includes a fixation component 10, a storage component 20, and a limiting component 30. The storage component 20 is openably installed on the fixation component 10. The fixation component 10 is adapted to be fixed to the skin surface of a patient. The limiting component 30 is disposed on the fixation component 10 and the storage component 20. The dialysis catheter 90 is adapted to be fixed by the limiting component 30 to prevent the dialysis catheter 90 from being pulled out quickly due to external force, causing misalignment or movement, and thus causing damage to the patient.

[0051] Similarly, the fixing component 10 includes a main body layer 11, an adhesive layer 12, a protective layer 13, and a mounting channel 14. The adhesive layer 12 is disposed on the main body layer 11, and the protective layer 13 is peelably disposed below the adhesive layer 12. That is, the protective layer 13 peelably covers the underside of the main body layer 11 through the adhesive layer 12. In other words, the main body layer 11, the adhesive layer 12, and the protective layer 13 are arranged and adhered sequentially from top to bottom. The mounting channel 14 extends downward from the surface of the main body layer 11 to penetrate the adhesive layer 12 and the protective layer 13.

[0052] The storage assembly 20 includes a storage shell 21, a storage cavity 22, and an outlet channel 23. The storage cavity 22 is located inside the storage shell 21 to store the dialysis tube 90. The storage shell 21 includes a peripheral shell 211 and a top shell 212, which are integrally connected. The fixing assembly 10 is operably installed below the storage shell 21, thereby surrounding the peripheral shell 211 and the top shell 212 to fix the dialysis tube 90 inside the storage cavity 22. The outlet channel 23 is disposed on the peripheral shell 211 of the storage shell 21. Furthermore, the outlet channel 23 extends outward from the inside of the peripheral shell 211 of the storage shell 21 to penetrate the peripheral shell 211. The outlet channel 23 communicates with the storage cavity 22, and the outermost end of the dialysis tube 90 is adapted to extend out of the outlet channel 23 for corresponding dialysis operations.

[0053] In this embodiment, the limiting component 30 includes a first limiting component 31 and a second limiting component 32, wherein the first limiting component 31 is disposed on the main body layer 11 of the fixing component 10. Specifically, the first limiting component 31 is adapted to open the installation channel 14, and the second limiting component 32 is disposed on the storage component 20. The dialysis tube 90 is adapted to be fixed in the storage component 20 by the first limiting component 31 and the second limiting component 32.

[0054] The first limiting component 31 includes a first extension 311, a second extension 312, and a holding unit 313 having a holding cavity 314 and a holding opening 315. The first extension 311 and the second extension 312 extend rearward from the holding unit 313 at a predetermined angle. The holding cavity 314 extends downward from the top of the holding unit 313 to penetrate the holding unit 313. The dialysis tube 90 is adapted to be placed in the holding cavity 314. The holding opening 315 is provided in the holding unit 313 to communicate with the mounting channel 14 of the fixing component 10. In other words, the first extension 311 and the second extension 312 are adapted to be squeezed, thereby opening the holding opening 315 and the mounting channel 14. The dialysis tube 90 is adapted to be placed into the holding cavity 314 through the holding opening 315 and the mounting channel 14. Then, the first extension 311 and the second extension 312 are released, and the holding opening 315 and the mounting channel 14 close again, so that the holding unit 313 can hold the dialysis tube 90 around its periphery to achieve a fixed effect. Based on this, the end of the dialysis tube 90 will not come into contact with the peritoneal dialysis tube fixing box 1A, avoiding additional contamination of the dialysis tube 90 and affecting the user.

[0055] Specifically, in this embodiment, the second limiting component 32 includes a rotating unit 321, a limiting groove 322, and a limiting channel 323. The rotating unit 321 is rotatably disposed on the top housing 212 of the storage component 20. The limiting groove 322 is located within the storage cavity 22 and surrounds the rotating unit 321. The limiting channel 323 is disposed below the rotating unit 321 and extends concavely upward from the lower part of the rotating unit 321.

[0056] Figure 6 This is a schematic diagram of the dialysis tube fixing state of a peritoneal dialysis tube fixing box according to the second embodiment of the present utility model.

[0057] First, when the dialysis catheter 90 extends from the patient's body, the holding opening 315 and the mounting channel 14 are opened by squeezing the first extension 311 and the second extension 312. The dialysis catheter 90 is then placed into the holding cavity 314 through the holding opening 315 and the mounting channel 14. Then, the first extension 311 and the second extension 312 are released, and the holding opening 315 and the mounting channel 14 close again, allowing the holding unit 313 to hold the dialysis catheter 90 around its periphery for a fixed effect. Then, the protective layer 13 is peeled off from the adhesive layer 12, and the adhesive layer 12 is adhered to the patient's skin surface.

[0058] like Figure 6 As shown, after the dialysis tube 90 is fixed by the first limiting component 31, it extends through the limiting channel 323 of the second limiting component 32. Then, the rotating unit 321 is rotated so that the dialysis tube 90 is wrapped around the limiting groove 322 and limited by the limiting channel 323, thereby better fixing the dialysis tube 90.

[0059] In summary, the peritoneal dialysis catheter fixation box 1A can fix the part of the dialysis catheter 90 located on the outside of the patient's body, ensuring that the dialysis catheter 90 and the patient's body are relatively stable, and preventing the dialysis catheter 90 from being pulled out quickly due to external force, causing misalignment or movement, and thus causing damage to the patient.
