Description

Technical Field

[0001] The utility model relates to the technical field of mechanical tools, in particular to a peritoneal dialysis tube fixing device. Background Art

[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Peritoneal dialysis (PD) is a dialysis method that uses the body's own peritoneum as a dialysis membrane. One end of the peritoneal dialysis catheter is placed in the patient's abdominal cavity, and the other end is located outside the human body and connected to a dialysate container. In order to fix the peritoneal dialysis catheter on the patient's abdomen, thereby avoiding catheter complications such as catheter blockage and damage caused by catheter folding, a common clinical practice is to stick the catheter on the patient's abdomen through a fixed patch. Referring to a peritoneal dialysis pipeline fixing device with a publication number of CN214596663U, in order to avoid bending of the pipeline, the middle part of the peritoneal dialysis catheter is wrapped in a fixed patch through the sticking part of the pipeline, and the middle part of the dialysis catheter is stuck on the skin through the fixed patch;

[0004] The above-mentioned fixation device uses a soft material for the fixation dressing, which has a strong adhesive bond and greatly reduces the possibility of catheter complications. However, the following problems still exist:

[0005] The middle part of the catheter is wrapped on a fixed dressing. Although the catheter is properly fixed and bending of the tube is avoided, the tail of the catheter is not fixed in the abdominal cavity. During use, the patient's movement will cause the tail to shake, causing the part of the catheter extending out of the fixed dressing to curl up, resulting in poor circulation in the catheter and affecting the dialysis effect. Utility Model Content

[0006] The utility model aims to provide a peritoneal dialysis tube fixing device, which can at least solve one of the above technical problems.

[0007] To achieve the above object, the utility model provides a peritoneal dialysis tube fixing device, comprising a fixing dressing, a fixing portion is arranged on one side of the fixing dressing, a semi-cylinder is arranged on the fixing portion, an extension portion is arranged on the upper side wall of the semi-cylinder, and a first winding strip and a second winding strip are arranged at the end of the extension portion;

[0008] A first adhesive sheet is arranged below the extension portion, and second adhesive sheets are arranged at the lower ends of the first and second wrapping strips. The catheter passes through the semi-cylinder, and the first and second wrapping strips are cross-wrapped around the tail end of the catheter. The first and second wrapping strips are fixed to the fixed patch through the second adhesive sheet.

[0009] It is further configured that the fixing portion is a semicircular gauze piece, and the horizontal side edge of the fixing portion is flush with the side edge of the fixing application.

[0010] It is further configured that the semi-cylinder is provided with a raised semi-cylinder in the center.

[0011] It is further configured that the semi-cylinder is larger than the outer diameter of the conduit.

[0012] It is further configured that the protruding portion is a rectangular strip-shaped patch, and the protruding portion protrudes outward to fix the patch.

[0013] It is further configured that the protruding portion is adhered to the side wall of the catheter through a first adhesive sheet.

[0014] It is further configured that the first wrapping strip and the second wrapping strip are applied in a rectangular strip shape.

[0015] It is further configured that the first winding strip and the second winding strip are symmetrically arranged on both sides of the extending portion along the midline of the extending portion.

[0016] It is further configured that the center lines of the first winding strip and the second winding strip are perpendicular to the center line of the extension portion.

[0017] It is further configured that the center line of the catheter is parallel to the center line of the fixed tube.

[0018] Beneficial effects of one or more of the above technical solutions:

[0019] After the catheter is fixed on the fixed dressing, the first winding strip and the second winding strip wrap the tail end of the catheter, and then fix it to the fixed dressing through the cross-arranged second adhesive sheet to prevent the tail end of the catheter from moving around the side of the fixed dressing and to prevent the tail end of the catheter from curling up.

[0024] 2 fixed plate; 21 semi-cylinder;

[0025] 3 extending strip; 31 first winding strip; 32 second winding strip; 33 first adhesive sheet; 34 second adhesive sheet; 4 catheter; 41 catheter tail end. Detailed implementation mode

[0026] The following combines with the attached drawings to illustrate the specific implementation mode of this embodiment.

[0027] Referring to Figure 1 and Figure 2 a peritoneal dialysis catheter fixing device is proposed by the utility model, which includes a bottom fixing dressing 1. A fixing piece 2 is arranged on one side edge of the fixing dressing 1. A semi-cylindrical tube 21 is arranged on the fixing piece 2. An extending part is arranged on the upper side wall of the semi-cylindrical tube 21. A first winding strip 31 and a second winding strip 32 are arranged at the end of the extending part.

[0028] A first sticking piece 33 is arranged below the extending part. Second sticking pieces 34 are arranged at the lower ends of the first winding strip 31 and the second winding strip 32. The catheter 4 passes through the semi-cylindrical tube 21. The first winding strip 31 and the second winding strip 32 are cross-wound around the tail end of the catheter 4. The first winding strip 31 and the second winding strip 32 are fixed on the fixing dressing 1 through the second sticking pieces 34.

[0029] The fixing piece 2 is a semi-circular gauze piece. The horizontal side edge of the fixing piece 2 is flush with the side edge of the fixing dressing 1. The semi-circular gauze piece is integrally arranged with the fixing dressing 1 to improve the overall strength of the fixing dressing 1 and avoid the situation that the fixing piece 2 is torn from the fixing dressing 1.

[0030] The semi-cylindrical tube 21 is set to bulge in the middle. The space provided by the semi-cylindrical tube 21 ensures that the catheter 4 can pass through.

[0031] The straight diameter of the semi-cylindrical tube 21 is larger than the outer diameter of the catheter 4 to ensure that the catheter 4 can pass through the semi-cylindrical tube 21.

[0032] The extending part is a rectangular strip-shaped dressing. The extending part extends outwards from the fixing dressing 1, so that the first winding strip 31 and the second winding strip 32 at the end of the extending part extend outwards by a part, ensuring that there is space for the first winding strip 31 and the second winding strip 32 to wind.

[0033] The extending part is pasted on the side wall of the catheter 4 through the first sticking piece 33. The first sticking piece 33 fixes the extending part, so that the first winding strip 31 and the second winding strip 32 will not rotate along the extending part during winding.

[0034] The first winding strip 31 and the second winding strip 32 are rectangular strip-shaped dressings, ensuring that the first winding strip 31 and the second winding strip 32 are flexible, improving the comfort of the patient, and at the same time ensuring the winding.

[0035] The first winding strip 31 and the second winding strip 32 are symmetrically arranged on both sides of the extending part along the middle line of the extending part. The center lines of the first winding strip 31 and the second winding strip 32 are perpendicular to the center line of the extending part. The first winding strip 31 and the second winding strip 32 extend towards both ends and are in a symmetrical structure, ensuring that the first winding strip 31 and the second winding strip 32 are on a straight line when fixed on the fixing dressing 1.

[0036] The center line of the catheter 4 is parallel to the center line of the fixing tube, ensuring that the catheter 4 will not deviate from the fixing dressing 1 after fixation, thereby improving the flowability of the catheter 4.

[0037] The fixing process of the fixing device is as follows:

[0038] First, the catheter 4 is passed through the cylindrical semi-cylinder 21 of the fixing plate 2, and the tail end 4 of the catheter is extended into the abdominal cavity. After the film below the fixing dressing 1 is torn off, the fixing dressing 1 is adhered to the abdomen. Then, the extension strip 3 is aligned with the catheter 4 so that the center line of the extension strip 3 is parallel to the axis of the catheter 4, and the extension strip 3 is adhered to the catheter 4 through the first adhesive sheet 33. At this time, the first winding strip 31 and the second winding strip 32 are both located above the catheter 4;

[0039] When wrapping, the first wrapping strip 31 is folded and passed through the gap between the catheter tail end 4 and the abdomen, and then folded in the direction away from the second wrapping strip 32. At this time, the first wrapping strip 31 is wrapped around the catheter tail end 4, and then the second adhesive piece 34 of the first wrapping strip 31 is attached to the fixed dressing 1 on one side of the catheter 4, and the second wrapping strip 32 is wrapped in the opposite direction, and the second adhesive piece 34 of the second wrapping strip 32 is attached to the fixed dressing 1 on the other side of the catheter 4. After the first wrapping strip 31 and the second wrapping strip 32 wrap the catheter tail end 41, they are fixed to the fixed dressing 1 through the cross-arranged second adhesive pieces 34 to prevent the catheter tail end 41 from moving on the side of the fixed dressing 1 and to prevent the catheter tail end 4 from tilting. During the fixing process, the outlet of the catheter tail end 41 is located in the center of the dressing, and the semi-cylinder 21 can wrap the extracorporeal catheter 4 inside, so that the dressing fits the tube better and avoids the indentation of the pipeline from damaging the skin.

[0040] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
