Description
Technical Field
The utility model belongs to the technical field of medical instrument makes, mainly relate to a medical instrument for nephrology dept, specifically speaking are noninvasive peritoneal dialysis device that resets.
Background
Renal replacement therapy is an important method of treating end-stage renal disease. Compared with hemodialysis, peritoneal dialysis has the advantages of simple operation, small influence on hemodynamics, capability of protecting residual renal function to the maximum extent and the like, and is widely applied to treatment of end-stage renal diseases at present. Although the technology of peritoneal dialysis is becoming more sophisticated, peritoneal dialysis patients still have associated complications of peritoneal dialysis catheters including catheter infection, dislodgement, blockage, macroreticular encapsulation, etc. which are inevitable. Among them, peritoneal dialysis catheter displacement is the most common catheter complication, which can directly cause poor drainage of peritoneal dialysis solution, resulting in peritoneal dialysis failure, and becomes one of the important reasons for patients to be hospitalized again and for dialysis failure to withdraw from peritoneal dialysis. Research shows that the incidence rate of catheter displacement reaches 12.7% -35%. When the peritoneal dialysis catheter has one-way drainage obstacle that the perfusion of the peritoneal dialysis solution is normal and the drainage is not smooth, the clinical manifestations are that the discharge quantity of the peritoneal dialysis solution is reduced, the flow rate is slowed down or stopped; the vertical abdominal plain film shows that the end of the peritoneal dialysis catheter is not in the true pelvis, and the peritoneal dialysis catheter displacement can be diagnosed. Researchers have long focused on inventing, improving peritoneal dialysis catheter techniques and procedures to reduce the incidence of catheter migration, but most local clinicians and patients still suffer from catheter migration.
Common treatment methods after catheter displacement include manual reduction, gravity reduction, guide wire reduction, laparoscopic reduction, and tube-drawing reduction, but the methods have many disadvantages: 1. the non-invasive reduction method has low success rate, 2, infection is easy to induce, and 3, the patient has high bearing cost, large operation wound, higher requirements on technology and equipment, difficult development in primary hospitals and the like.
Disclosure of Invention
The utility model aims at providing a can be outside the patient body, through the noninvasive peritoneal dialysis that resets of noninvasive technical operation messenger's aversion pipe resets again device that does not have.
The technical scheme of the utility model is that:
a noninvasive reduction peritoneal dialysis device comprises a peritoneal dialysis catheter consisting of a terylene sleeve I1, a terylene sleeve II 2, an intra-abdominal section 3, a subcutaneous tunnel 4 and an extra-abdominal section 5, wherein the intra-abdominal section 3, the subcutaneous tunnel 4 and the extra-abdominal section 5 are divided by the terylene sleeve I1 and the terylene sleeve II 2;
the magnetic alloy 7 is in the shape of a fiber rope;
the magnetic alloy 7 is in the shape of 16-20 fiber ropes;
the peritoneal dialysis catheter has an outer diameter of 0.8cm and an inner diameter of 0.5cm, wherein the length of an intra-abdominal section is 3 cm to 10 cm, the length of a subcutaneous tunnel 4 is 2 cm to 7cm, and the length of an extra-abdominal section is 5cm to 14 cm to 20 cm; the length of the polyester sleeve I1 and the polyester sleeve II 2 is 0.75-1cm, the outer diameter is 0.9cm, and the inner diameter is 0.8 cm;
