Description

Technical Field

[0001] The present invention relates to the technical field of fixing devices, and particularly relates to an external catheter fixing device for peritoneal dialysis. Background Art

[0002] Peritoneal dialysis (PD) utilizes the characteristics of the peritoneum as a semi-permeable membrane. Through the action of gravity, the prepared dialysis solution is regularly and periodically infused into the peritoneal cavity of the patient through a catheter. Due to the concentration gradient difference of solutes on both sides of the peritoneum, solutes on the high-concentration side move to the low-concentration side (diffusion effect); water moves from the low-osmotic side to the high-osmotic side (osmosis effect). By continuously replacing the peritoneal dialysis fluid, the purpose of removing metabolites, toxic substances in the body and correcting water and electrolyte balance disorders is achieved. During the dialysis process, a disposable external short catheter for peritoneal dialysis is an indispensable instrument. It can connect the dialysis fluid bag and the peritoneal cavity of the patient, enabling the smooth inflow and outflow of the dialysis fluid and providing effective treatment for the patient. Therefore, how to better protect and fix the external short catheter for peritoneal dialysis is one of the main issues that nursing staff need to consider.

[0003] An existing external catheter fixing device for peritoneal dialysis (Publication No.: CN221309051U) has at least the following drawbacks: When the above patent is used, the external catheter for peritoneal dialysis is fixed through a magic tape and a locking component. Since peritoneal dialysis lasts for a long time, usually at night, the way of bonding with the magic tape needs to go around the patient's waist for a circle. Leaning on the patient's waist for a long time will cause discomfort to the patient and affect the comfort of the patient's peritoneal dialysis. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art, and to propose an external catheter fixing device for peritoneal dialysis.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions: An external catheter fixing device for peritoneal dialysis, comprising an adhesive tape body and a box body. Two first adhesive tapes are symmetrically arranged on the surface of the adhesive tape body. A second adhesive tape is arranged on the surface of the adhesive tape body. The second adhesive tape is arranged between the two first adhesive tapes. The second adhesive tape and the two first adhesive tapes are alternately arranged. An opening is penetrated through the outer surface of the box body near the bottom. The second adhesive tape and the two first adhesive tapes are inserted into the opening. A placement groove is arranged on the upper surface of the box body. The placement groove is arranged in an S shape. A cover plate is hinged on the outer surface of one side of the box body. Two buckles are symmetrically arranged on the outer surface of the other side of the box body. Two buckles are fixedly installed on the outer surface of the cover plate near the two buckles. The two buckles are matched with the two buckles. Anti-adhesive films are arranged on the lower surfaces of the adhesive tape body, the second adhesive tape and the two first adhesive tapes.

[0006] As a further solution of the present invention, through holes are formed inside the box body. On the inner wall of the through hole close to the bayonet, two limiting sliding columns are symmetrically and fixedly installed. A sliding plate is slidably installed on the outer surfaces of the two limiting sliding columns. A connecting block is fixedly installed on the outer surface on the other side of the through hole.

[0007] As a further solution of the present invention, a pressing plate is arranged between the connecting block and the sliding plate. Two connecting pieces are symmetrically and rotatably installed on the outer surfaces of the opposite sides of the pressing plate. The top end of one of the connecting pieces is rotatably connected to the outer surface of the connecting block, and the top end of the other connecting piece is rotatably connected to the outer surface of the sliding plate.

[0008] As a further solution of the present invention, a jack is formed through the outer surface of the box body close to the bayonet. An elastic top block is fixedly installed on the outer surface of the box body close to the bayonet. The bottom end of the elastic top block is inserted into the inside of the jack. The bottom end of the elastic top block penetrates through the jack and abuts against the outer surface of the sliding plate. Through the elastic deformation ability of the top of the elastic top block, the elastic top block can be elastically restored after being compressed. The elastic top block is arranged in an L shape and is inclined. A pressing block is fixedly installed on the outer surface of the cover plate close to the elastic top block. An inclined surface is formed at the bottom of the pressing block, and the inclined surface abuts against the outer surface of the elastic top block.

[0009] As a further solution of the present invention, two groups of sinking grooves are symmetrically formed in pairs on the upper surface of the box body. One group of two sinking grooves are respectively arranged on both sides of the placing groove. Two sliding grooves are symmetrically formed on the outer surface of the box body close to the two sinking grooves. The two sliding grooves are arranged between the two sinking grooves. The inner walls of the two sinking grooves are both slidably installed with inclined blocks. The inner walls of the two sliding grooves are both slidably installed with clamping blocks. One end of the clamping block close to the sinking groove penetrates through the inner wall of the sinking groove and is fixedly installed on the outer surface of the inclined block. A fillet is formed on the outer surface of the clamping block close to the top end.

[0010] As a further solution of the present invention, springs are arranged inside the two sinking grooves. One end of each spring is fixedly installed on the outer surface of the inclined block, and the other end of each spring is fixedly installed on the inner wall of the sinking groove far from the placing groove. A plurality of triangular pushing blocks are fixedly installed on the upper surface of the cover plate close to the inclined block. An inclined angle matching the triangular pushing block is formed on the outer surface of the inclined block.

[0011] As a further solution of the present invention, two positioning holes are symmetrically formed through the outer surface of the adhesive tape body. Two positioning columns are arranged on the lower surface of the box body, and the two positioning columns are arranged in a matching manner with the two positioning holes.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. When in use, paste the adhesive tape body, the first adhesive tape and the second adhesive tape flat on the skin of the patient's abdomen. At this time, the position of the box body is fixed for subsequent use; the operator places the peritoneal dialysis external catheter inside the placement groove. When placing it, press the peritoneal dialysis external catheter forcefully so that the peritoneal dialysis external catheter is clamped between the two clamping blocks. By using this device to fix the peritoneal dialysis external catheter, it only needs to be pasted at the designated position on the patient's abdominal skin, and the patient will not feel uncomfortable during long-term peritoneal dialysis; 2. Drive the triangular push block to move downward through the cover plate. The triangular push block abuts against the bevel angle of the inclined block through its own hypotenuse, so that the inclined block drives the two clamping blocks to separate. At this time, the liquid inside the peritoneal dialysis external catheter can flow normally, and the clamping blocks flatten and seal the peritoneal dialysis external catheter under the action of the spring. By using this device to flatten and seal the peritoneal dialysis external catheter, it is ensured that the liquid inside the peritoneal dialysis external catheter can only flow after the cover plate is properly covered.

A placement groove 21 is opened on the upper surface of the box body 4. The placement groove 21 is arranged in an S shape. A cover plate 5 is hinged on the outer surface of one side of the box body 4. Two bayonets 10 are symmetrically opened on the outer surface of the other side of the box body 4. Two buckles 11 are fixedly installed on the outer surface of the cover plate 5 near the two bayonets 10. The two buckles 11 are matched with the two bayonets 10. Anti-adhesive films are arranged on the lower surfaces of the adhesive tape body 1, the second adhesive tape 3 and the two first adhesive tapes 2. Two positioning holes 8 are symmetrically penetrated through the outer surface of the adhesive tape body 1. Two positioning columns 7 are arranged on the lower surface of the box body 4. The two positioning columns 7 are matched with the two positioning holes 8.

[0019] During use, the user inserts the first adhesive tape 2 and the second adhesive tape 3 on the adhesive tape body 1 into the opening 9, and then aligns the positioning posts 7 on the box body 4 with the positioning holes 8 to facilitate the positioning of the position of the box body 4.

[0022] In this embodiment, two groups of sinking grooves 22 are symmetrically arranged in pairs on the upper surface of the box body 4. One group of two sinking grooves 22 are respectively arranged on both sides of the placing groove 21. Two sliding grooves 23 are symmetrically arranged on the outer surface of the box body 4 near the two sinking grooves 22. The two sliding grooves 23 are arranged between the two sinking grooves 22. The inner walls of the two sinking grooves 22 are both slidably installed with inclined blocks 27. The inner walls of the two sliding grooves 23 are both slidably installed with clamping blocks 24. One end of the clamping block 24 close to the sinking groove 22 penetrates through the inner wall of the sinking groove 22 and is fixedly installed on the outer surface of the inclined block 27. The outer surface of the clamping block 24 near the top is provided with a fillet. Springs 25 are arranged inside the two sinking grooves 22. One end of the spring 25 is fixedly installed on the outer surface of the inclined block 27. The other end of the spring 25 is fixedly installed on the inner wall of the sinking groove 22 far away from the placing groove 21. A plurality of triangular pushing blocks 26 are fixedly installed on the upper surface of the cover plate 5 close to the inclined block 27. The outer surface of the inclined block 27 is provided with an inclined angle matching the triangular pushing block 26.

[0023] The operator places the peritoneal dialysis external catheter inside the placing groove 21. When placing it, press the peritoneal dialysis external catheter forcefully so that the peritoneal dialysis external catheter is clamped between the two clamping blocks 24. The peritoneal dialysis external catheter is fixed by this device and only needs to be attached to the designated position on the patient's abdominal skin, and it will not cause discomfort to the patient during long-term peritoneal dialysis; the clamping block 24 clamps and seals the peritoneal dialysis external catheter under the action of the spring 25. The peritoneal dialysis external catheter is clamped and sealed by this device to ensure that the liquid inside the peritoneal dialysis external catheter can only flow after the cover plate 5 is covered well; the cover plate 5 drives the triangular pushing block 26 to move downward. The hypotenuse of the triangular pushing block 26 abuts against the inclined angle of the inclined block 27, so that the inclined block 27 drives the two clamping blocks 24 to separate. At this time, the liquid inside the peritoneal dialysis external catheter can flow normally.

[0024] It should be noted that when the present invention is in use, the user inserts the first adhesive tape 2 and the second adhesive tape 3 on the adhesive tape body 1 into the opening 9, and then aligns the positioning posts 7 on the box body 4 with the positioning holes 8 to facilitate the positioning of the position of the box body 4; then the operator tears off the anti-adhesive films on the lower surfaces of the adhesive tape body 1, the first adhesive tape 2 and the second adhesive tape 3, and the anti-adhesive films of the first adhesive tape 2 and the second adhesive tape 3 located inside the opening 9 do not need to be removed, and then the adhesive tape body 1, the first adhesive tape 2 and the second adhesive tape 3 are pasted flat on the skin of the patient's abdomen. At this time, the position of the box body 4 is fixed for subsequent use; the operator places the peritoneal dialysis external catheter into the placement groove 21. When placing it, press the peritoneal dialysis external catheter forcefully to make the peritoneal dialysis external catheter snap into the space between the two clamping blocks 24. The peritoneal dialysis external catheter is fixed by this device. It only needs to be pasted at the designated position on the abdominal skin of the patient, and the patient will not feel uncomfortable during long-term peritoneal dialysis; the clamping blocks 24 flatten and seal the peritoneal dialysis external catheter under the action of the spring 25. The peritoneal dialysis external catheter is flattened and sealed by this device to ensure that the liquid inside the peritoneal dialysis external catheter can only flow after the cover plate 5 is properly covered; the downward pressure of the cover plate 5 drives the pressing block 14 to move downward, and the pressing block 14 drives the elastic top block 13 to move, so that the elastic top block 13 pushes the sliding plate 18, and the sliding plate 18 makes the pressing plate 19 move downward through the connecting piece 20, firmly pressing the first adhesive tape 2 and the second adhesive tape 3, ensuring that the box body 4 will not slide or shift. The cover plate 5 firmly fixes the peritoneal dialysis external catheter inside the placement groove 21 through the buckle 11 and the bayonet 10. Since the placement groove 21 is S-shaped, the peritoneal dialysis external catheter will rub against the inner wall of the placement groove 21 when sliding up and down, thereby restricting the up and down position of the peritoneal dialysis external catheter; the cover plate 5 drives the triangular push block 26 to move downward, and the triangular push block 26 abuts against the bevel of the inclined block 27 through its own bevel, so that the inclined block 27 drives the two clamping blocks 24 to separate. At this time, the liquid inside the peritoneal dialysis external catheter can flow normally.
