[0002] Peritoneal dialysis is a process of water and solute exchange between the dialysate infused into the peritoneal cavity and the blood in the peritoneal capillaries using the Donnan equilibrium principle. Before peritoneal dialysis treatment, a peritoneal dialysis catheter needs to be surgically placed in the Douglas groove of the peritoneal cavity. The peritoneal dialysis catheter consists of a silicone rubber tube and two polyester sleeves, with a main hole and a side hole at the end of the tube. After the dialysis catheterization surgery, the peritoneal dialysis catheter with the main hole and the side hole enters the abdominal cavity through the peritoneum, the Cuff segment in the rectus abdominis is buried in the rectus abdominis sheath, and the Cuff segment in the subcutaneous tunnel is buried subcutaneously. The external short tube is connected to the subcutaneous tunnel segment through a titanium joint, and fresh peritoneal dialysis fluid is infused and waste fluid is drained through the external short tube. The peritoneal dialysis catheter is left in the abdominal cavity for a long time, which may cause the main hole and the side hole to be blocked by fibrin, or be wrapped by the greater omentum, resulting in poor drainage of peritoneal dialysis fluid, affecting the peritoneal dialysis treatment effect of patients with uremia.
[0003] Currently, it is inconvenient to clear the main hole and side hole of the peritoneal dialysis catheter, and some patients are forced to have their catheter removed due to severe or repeated blockage, and are forced to terminate peritoneal dialysis treatment. Utility Model Content

DETAILED DESCRIPTION
[0024] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.
[0025] Combined with this Figures 1 to 4 The following describes an embodiment of a peritoneal dialysis catheter unclogging device. Specifically, the peritoneal dialysis catheter unclogging device is constructed as a split structure, which has a brush 10, a side passage tube 11, and a guide wire 8. The brush 10 and the end of the side passage tube 11 are bent and closely fit along the inner wall of the peritoneal dialysis catheter. When the guide wire 8 passes through the blocked nutrient solution, the brush 10 is driven to effectively unblock the nutrient solution on the inner wall of the peritoneal dialysis catheter.
[0026] Please refer to Figures 1 to 4 A peritoneal dialysis catheter unblocking device comprises: a fixing seat 14, a guide wire 8 is passed through and arranged on the fixing seat 14, a drug injection tube 9 is fixedly connected to the bottom of the guide wire 8, a uniformly distributed brush 10 is fixedly connected to the outer wall of the drug injection tube 9, a liquid injection port 1 is passed through and arranged on the top of the fixing seat 14, the liquid injection port 1 passes through the fixing seat 14 and is arranged with an infusion hole 15, and the infusion hole 15 passes through the guide wire 8 and is connected to the drug injection tube 9, a side through tube 11 is passed through and arranged on the outer wall of the drug injection tube 9, a front through tube 13 is passed through and arranged on the bottom of the drug injection tube 9, and arc-shaped blades 12 are fixedly connected to the middle of the front end of the drug injection tube 9 and around.
[0027] The brush 10 is bent at the end of the side passage 11 and closely fits along the inner wall of the peritoneal dialysis catheter. When the guide wire 8 enters the catheter, the brush 10 at the end thereof completes the dredging when it is in contact. The guide wire 8 is provided with a drug injection tube 9 and a brush 10. When the guide wire 8 enters the inner wall of the side passage 11, the brush 10 on the guide wire 8 can be swept to dredge.
[0028] When the injection tube at one end of the guide wire 8 enters along the injection end of the peritoneal dialysis catheter, the brush 10 is bent with the end of the side passage 11 and fits tightly along the inner wall of the peritoneal dialysis catheter. When the guide wire 8 passes through the blocked nutrient solution, the brush 10 is driven to effectively clear the nutrient solution on the inner wall of the peritoneal dialysis catheter, thereby achieving full clearing of the blockage inside the peritoneal dialysis catheter and reducing the clearing frequency of the peritoneal dialysis catheter. By rotating the injection tube through the fixed seat 14, the side passage 11 and the side tube of the peritoneal dialysis catheter can be relatively engaged, and the arc blades 12 clear the nutrient solution in the front tube, so that the front passage 13 corresponds to the front tube of the peritoneal dialysis catheter. By injecting liquid medicine into the injection port 1, the liquid medicine will flow out from the side passage 11 and the front passage 13 through the infusion hole 15 and the injection tube in turn, so that the clearing effect of the device is better. The device is disinfected after use to avoid the trauma and infection risks caused by reoperation of uremic patients due to poor peritoneal dialysis catheter function.

[0030] The handle 2 facilitates the rotation of the fixing base 14 .
[0031] The front and rear ends of the fixing seat 14 are fixedly connected with uniformly distributed anti-skid protrusions 5 .
[0032] The anti-slip protrusions 5 make it easier for the user to hold the fixing base 14 to avoid slipping out of the user's hands.
[0033] The bottom of the fixed seat 14 is fixedly connected with slide cylinders 6 all around, the inner walls of the four slide cylinders 6 are slidably connected with slide rods 3, the bottoms of the four slide rods 3 are fixedly connected to the fixed plate 4, and the top of the outer wall of the fixed plate 4 is penetrated and provided with a marking groove 7.
[0034] A groove 16 is provided at the center of the fixing plate 4 , and a block 17 is slidably connected to the inner wall of the groove 16 . A sliding groove 18 is provided on the inner wall of the guide wire 8 , and the sliding groove 18 fits with the block 17 .

The other end of the screw rod 20 is fixedly connected to a rotating block 22.
[0036] By sliding the slide bar 3 in the slide cylinder 6, the fixed plate 4 can slide along the guide wire 8, so that the fixed plate 4 is close to the peritoneal dialysis catheter, and the marking groove 7 corresponds to the position of the side passage tube 11, so that the position of the side passage tube in the peritoneal dialysis catheter can be confirmed through the marking groove 7 on the fixed plate 4, so as to facilitate the insertion of the side passage tube 11 corresponding to the side tube of the peritoneal dialysis catheter. When the position of the side passage tube in the peritoneal dialysis catheter is confirmed through the marking groove 7 on the fixed plate 4, the rotating block 22 can be rotated to drive the screw rod 20 fixed thereto to rotate. During rotation, the screw rod 20 moves horizontally, thereby making the telescopic rod 19 connected thereto slide along the lower surface of the fixed seat 14. During the sliding process, the block 17 on the telescopic rod 19 slides outward along the groove 16 and engages in the slide groove 18 to achieve limited fixation of the fixed seat 14. At this time, the position of the side passage tube in the peritoneal dialysis catheter can be confirmed.
