Description

Technical Field

[0001] The utility model belongs to the field of waist belts, and in particular relates to a peritoneal dialysis waist belt. Background Art

[0002] Peritoneal dialysis is one of the main renal replacement therapies for end-stage renal disease. The peritoneal dialysis catheter needs to be retained in the patient's abdomen and is called the patient's lifeline. The peritoneal dialysis belt is used to place and fix the peritoneal dialysis catheter.

[0003] Chinese patent publication number CN218923387U discloses a Velcro peritoneal dialysis belt. The belt is closed by Velcro 2 and is provided with a placement bag, Velcro 1, and a guide tube. Velcro 1 is used to fix the titanium connector portion of the peritoneal dialysis catheter. When changing the fluid, only the external short tube placed in the placement bag needs to be taken out.

[0004] During use of the Velcro peritoneal dialysis belt disclosed in the application, the titanium connector of the peritoneal dialysis catheter is partially placed in the groove of the guide tube, thereby reducing the risk of the titanium connector loosening and the short tube falling off. When replacing the external short tube, the titanium connector needs to be pulled out of the guide tube, which can easily cause pulling on the extra-abdominal section of the peritoneal dialysis catheter. In addition, the Velcro is difficult to effectively fix the peritoneal dialysis catheter, and the external short tube and the extra-abdominal section of the peritoneal dialysis catheter are easily pulled by external forces. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a peritoneal dialysis belt.

DETAILED DESCRIPTION

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] See also Figure 1-3 As shown, in this embodiment, a peritoneal dialysis belt is provided, including a belt body 1 and a dialysis catheter 7. A support plate 2 is installed on the belt body 1, and a placement bag 3 is installed on one side of the support plate 2. The support plate 2 is located between the placement bag 3 and the belt body 1, and the dialysis catheter 7 and the support plate 2 are located on the same side of the support plate 2. Two screws 6 are rotatably fitted in the support plate 2, and a knob 601 is installed at one end of the screw 6. The surface of the knob 601 is provided with anti-slip grooves, thereby increasing the roughness of the surface of the knob 601 and facilitating twisting and rotation. The knob 601 is rotatably fitted on one side of the support plate 2, and two moving parts 4 corresponding to the screw 6 are slidably fitted in the support plate 2. A clamping part 5 corresponding to the dialysis catheter 7 is installed on one side of the moving part 4. The clamping part 5 is slidably fitted on one side of the support plate 2, and a card slot 502 is opened in the horizontal direction of the clamping part 5. Two hard cylinders 704 are installed on the circumference of the dialysis catheter 7, and a clamping ring 705 is installed on the circumference of the hard cylinder 704. The clamping ring 705 corresponds to the card slot 502.

[0026] One aspect of the application of this embodiment is as follows: when in use, the dialysis catheter 7 is placed between the two clamping members 5 on the same screw 6, and the clamping ring 705 is aligned with the card slot 502, then the knob 601 is turned to drive the screw 6 to rotate, and the rotation of the screw 6 drives the two moving members 4 to move closer to each other, and the displacement of the moving member 4 drives the clamping member 5 to move synchronously, so that the two clamping members 5 are close to clamp and fix the hard cylinder 704, and at the same time, the clamping ring 705 is clamped into the card slot 502, completing the fixed installation of the dialysis catheter 7. Similarly, the dialysis catheter 7 is disassembled with reference to the above operation.

[0027] The dialysis catheter 7 of this embodiment includes a titanium joint 701, the upper and lower ends of which are respectively connected to an external tube 702 and a peritoneal tube 703. The end of the titanium joint 701 is clamped into the external tube 702 or the peritoneal tube 703 for connection and fixation. Two hard tubes 704 are respectively installed on the circumference of the external tube 702 and the peritoneal tube 703. The titanium joint 701 is located between the external tube 702 and the peritoneal tube 703, and the external tube 702 can be easily replaced through the titanium joint 701.

[0028] In this embodiment, a circular plate 602 is installed at one end of the screw 6, and a rotating ring 603 is installed on the circumference of the screw 6.
