Description

Technical Field

[0001] The present application relates to the technical field of pipeline fixation and disinfection, and in particular to a peritoneal dialysis extracorporeal tube fixation and disinfection device. Background Art

[0002] Peritoneal dialysis utilizes the peritoneum as a semipermeable membrane. Prepared dialysate is infused into the patient's peritoneum via a catheter under gravity. The peritoneal dialysis catheter is essential for maintaining peritoneal dialysis fluid exchange and serves as a permanent indwelling pathway for dialysis. It consists of a peritoneal dialysis catheter, a titanium connector, and a short external tubing. Given that daily activities can pull on the extracorporeal tubing at the dialysis tubing outlet, it is often necessary to secure the tubing.

[0003] In the related art, Chinese patent application number CN202220367259.X proposes a peritoneal dialysis belt, which includes a belt body, a buckle at one end of the belt body, a button at the other end, and at least three buttonholes evenly distributed along the length of the belt body that can be fixed together with the buckle. A storage bag that can fix a dialysis catheter head is provided on the belt body near the buckle, and a fixing ring that can pass the dialysis catheter is provided on the belt body between the storage bag and the buckle. When the extracorporeal tube does not need to be disinfected, the dialysis catheter can be passed through the fixing ring and the dialysis catheter head can be inserted into the storage bag. When the extracorporeal tube needs to be disinfected, the dialysis catheter head can be removed from the storage bag and the part to be disinfected can be immersed in a bottle of disinfectant for disinfection.

[0004] In the aforementioned related technologies, the retaining ring and holding bag can only be used to hold the in vitro tube in place, preventing it from being pulled by swinging. However, the tube can still move along its length within the retaining ring, making it susceptible to being pulled and falling off. Furthermore, to disinfect the in vitro tube, the patient must hold the tube with one hand and the bottle of disinfectant with the other to ensure it remains submerged in the disinfectant. This requires both hands to be occupied for a long time, making the disinfection process more cumbersome. Utility Model Content

[0005] In order to improve the problem that the extracorporeal tube is difficult to be stably fixed and the disinfection requires the patient's hands to be occupied for a long time, making the disinfection process more troublesome, the present application provides a peritoneal dialysis extracorporeal tube fixing and disinfection device.

[0006] The present application provides a peritoneal dialysis extracorporeal tube fixing and disinfection device that adopts the following technical solution:

[0007] A peritoneal dialysis extracorporeal tube fixing and disinfection device, comprising

[0008] A fixing belt for the patient to wear, wherein the fixing belt is provided with a fixing component for clamping the extracorporeal tube so that the extracorporeal tube is stably fixed on the fixing belt;

[0009] a bottle body, which is arranged on the fixing belt, and contains a disinfectant for disinfecting the extracorporeal tube, and a through hole is provided on the top of the bottle body for inserting the extracorporeal tube; and

[0010] The clamping piece is arranged at the perforation of the bottle body and can clamp the extracorporeal tube so that the extracorporeal tube is stably suspended in the bottle body for disinfection.

[0011] Furthermore, the fixing assembly includes a pressure plate fixedly mounted on the fixing belt, a pressure strip movably fastened to the pressure plate, and a fastener arranged between the pressure plate and the pressure strip, and the pressure strip is fastened to the pressure plate by the fastener.

[0012] Furthermore, the pressing plate is provided with a groove adapted to the extracorporeal tube, and the pressing strip is provided with a convex strip for pressing the extracorporeal tube tightly into the groove.

[0013] Furthermore, the bottle body includes a bottle body with an opening at the top and a bottle cap that is movable and covers the open end of the bottle body, and the through hole is located in the middle of the bottle cap.

[0014] Furthermore, the clamping member is configured as an annular plug which is sleeved on the extracorporeal tube. By inserting the annular plug into the perforation, the annular plug deforms and squeezes the extracorporeal tube, so that the extracorporeal tube can be stably suspended in the bottle for disinfection.

[0015] Furthermore, the bottle body is provided with a clip for detachably mounting the bottle body on the fixing belt.

[0016] Furthermore, the fixing belt is provided with a buckle for adjusting the tightness of the fixing belt.

[0017] Furthermore, the fixing belt is made of breathable material.

[0028] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] The present application discloses a device for fixing and disinfecting an extracorporeal peritoneal dialysis tube. Figure 1 and Figure 2A peritoneal dialysis extracorporeal tube fixing and disinfection device includes a fixing belt 1, a fixing assembly 2, and a bottle body 3. The fixing belt 1 is made of a breathable material, such as a non-woven elastic bandage. A buckle 9 is installed on the fixing belt 1. The buckle 9 is configured as a belt buckle. The fixing belt 1 can be adjusted according to the patient's body shape, so that the belt buckle can fasten both ends of the fixing belt 1 to ensure that the fixing belt 1 can be stably worn around the patient's waist. The fixing assembly 2 is arranged on the fixing belt 1 and can clamp and fix the extracorporeal tube to avoid the risk of the extracorporeal tube being pulled and falling off. The bottle body 3 is arranged on the fixing belt 1. The bottle body 3 contains disinfectant for disinfecting the extracorporeal tube. A through-hole 4 for inserting the extracorporeal tube is provided on the top of the bottle body 3. The patient can carry the bottle body 3 filled with disinfectant around his waist through the fixing belt 1, and the extracorporeal tube can penetrate the through-hole 4 and be inserted into the bottle body 3 for soaking and disinfection. This process can be performed without the patient holding it. In order to prevent the extracorporeal tube from freely escaping from the perforation 4 of the bottle body 3 and affecting the disinfection effect of the extracorporeal tube, a clamping piece for clamping the extracorporeal tube is provided at the perforation 4 of the bottle body 3, so that under the clamping action of the clamping piece, the extracorporeal tube is stably suspended in the bottle body 3 for disinfection.

[0030] Considering the comfort of using the device, refer to Figure 1 and Figure 2The fixing assembly 2 includes a pressure plate 21 fixedly mounted on the fixing belt 1, a pressure strip 22 movably buckled on the pressure plate 21, and a fastener 23 provided between the pressure plate 21 and the pressure strip 22. The pressure plate 21 and the pressure strip 22 are both made of silicone material. Both ends of the pressure plate 21 are stably connected to the fixing belt 1. One end of the pressure strip 22 is rotatably connected to one end of the pressure plate 21, and the other end can be rotated toward the pressure plate 21 and fastened to the pressure plate 21 through the fastener 23. The fastener 23 can be a snap fastener provided between the pressure plate 21 and the pressure strip 22, or a pair of Velcro adhesive tapes that adhere to each other. In the embodiment of the present application, the fastener 23 is provided as a snap fastener. Under the action of the fastener 23, the pressure strip 22 can be stably pressed and fitted on the pressure plate 21, so that the extracorporeal tube can be clamped and fixed by the pressure strip 22 and the pressure plate 21. To ensure that the pressure plate 21 and the pressure strip 22 can stably clamp the extracorporeal tube, the pressure plate 21 has a plurality of grooves 6 on the surface near the pressure strip 22 that are compatible with the extracorporeal tube. The grooves 6 are spaced apart along the length of the fixing band 1, and the length of the grooves 6 coincides with the width of the fixing band 1. Both ends of the grooves 6 are open. Correspondingly, the pressure strip 22 has a plurality of protruding strips 7 on the surface near the pressure plate 21 that are compatible with the grooves 6. When the extracorporeal tube needs to be fixed and clamped, the extracorporeal tube can be bent along the direction of the grooves 6 and inserted into the grooves 6 of the pressure plate 21. The pressure strip 22 is then fastened to the pressure plate 21 using the fastener 23. The extracorporeal tube is now firmly fixed in the grooves 6 by the protruding strips 7. When sterilization is not required, the extracorporeal tube is stably fixed between the pressure plate 21 and the pressure strip 22 without damage due to the pressure of the protruding strips 7, effectively reducing the risk of the tube falling out.

[0031] Reference Figure 1 、 Figure 3 and Figure 4 The bottle body 3 includes a bottle body 31 with an opening at the top and a bottle cap 32 with a removable cover on the open end of the bottle body 31. The bottle body 31 and the bottle cap 32 are both made of plastic, and the bottle cap 32 is threaded and detachably covered on the opening at the top of the bottle body 31. A perforation 4 is located in the middle of the bottle cap 32, through which an extracorporeal tube can be inserted into the disinfectant in the bottle body 31 for disinfection. Considering that the disinfectant cannot be reused and to avoid the risk of infection, the bottled disinfectant can be directly placed into the bottle body 31. The cavity in the bottle body 31 is just the right size to fit the bottle of the bottled disinfectant. The bottle cap 32 is then closed, so that the bottled disinfectant is stably stored in the bottle body 3. At this time, the extracorporeal tube can be inserted into the bottled disinfectant through the perforation 4 on the bottle cap 32 for immersion disinfection. After the disinfection is completed, the bottled disinfectant only needs to be removed from the bottle body 3 and discarded, without the need to disinfect the bottle body 3.

[0032] In order to ensure that the in vitro tube is not easy to come out of the bottle body 3 when the in vitro tube is disinfected, Figure 1 、 Figure 3 and Figure 4 The clamping member is configured as an annular soft plug 5, which is made of rubber and can deform when squeezed. Therefore, when the in vitro tube needs to be disinfected, the annular soft plug 5 can be sleeved onto a suitable position on the in vitro tube, and then inserted into the bottled disinfectant in the bottle body 3 through the perforation 4. Simultaneously, the annular soft plug 5 is pressed into the perforation 4 of the cap body. Under the pressure of the inner wall of the perforation 4, the annular soft plug 5 deforms and can tightly cover the in vitro tube. At this point, the in vitro tube is stably clamped at the perforation 4 of the bottle cap 32, allowing it to be stably suspended in the bottled disinfectant for disinfection. At the same time, the friction between the annular soft plug 5 and the in vitro tube can also prevent the in vitro tube from escaping from the bottle body 3, ensuring that the in vitro tube can be fully disinfected.

[0033] In order to avoid the bottle 3 affecting the patient's daily life, Figure 3 The bottle body 31 is provided with a clip 8 for detachably mounting the bottle body 31 on the fixing belt 1. The clip 8 is made of spring steel and can stably mount the bottle body 31 on the fixing belt 1. After the extracorporeal tube is sterilized, the bottle body 3 with the clip 8 can be removed from the fixing belt 1, so that the patient no longer needs to carry the bottle body 3, thereby preventing the bottle body 3 from interfering with the patient's daily activities.

[0034] The implementation principle of the peritoneal dialysis extracorporeal tube fixing and disinfection device according to the embodiment of the present application is as follows: first, the fixing belt 1 is worn around the patient's waist, and the extracorporeal tube is bent along the direction of the groove 6 and embedded into the groove 6 of the pressing plate 21; then, the pressure strip 22 is fastened to the pressing plate 21 by the fastener 23. At this time, the extracorporeal tube is pressed and fixed in the groove 6 by the convex strip 7, so that when disinfection is not required, the extracorporeal tube is stably fixed between the pressing plate 21 and the pressure strip 22 without damage under the pressure of the convex strip 7, effectively reducing the risk of the tube falling off.

[0035] When the in vitro tube needs to be disinfected, the bottle body 3 is first hooked onto the fixing belt 1 via the clamp 8, and the bottled disinfectant is placed into the bottle body 31 while the bottle cap 32 is closed. The annular plug 5 is then sleeved onto the appropriate position of the in vitro tube and inserted into the bottled disinfectant in the bottle body 3 through the perforation 4. The annular plug 5 is simultaneously pressed into the perforation 4 of the cap. The perforation 4 compresses the annular plug 5, causing it to deform and tightly wrap around the in vitro tube. The in vitro tube is now stably clamped in the perforation 4 of the bottle cap 32, allowing it to be stably suspended in the bottled disinfectant for disinfection. The friction between the annular plug 5 and the in vitro tube also prevents the tube from coming out of the bottle body 3, ensuring that the in vitro tube can be fully disinfected.

[0036] After the disinfection work is completed, the annular soft plug 5 can be pulled out from the perforation 4 of the bottle cap 32, and the annular soft plug 5 can be removed from the extracorporeal tube at the same time; then the extracorporeal tube can be pulled out from the bottle body 3 and fixed by the pressing plate 21 and the pressure strip 22; finally, the bottle body 3 can be removed, the bottle cap 32 can be opened from the bottle body 31, and the used bottled disinfectant can be taken out and discarded.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
