Description
Technical Field
The utility model relates to the technical field of peritoneal dialysis catheters, in particular to a positioning pipeline of a peritoneal dialysis catheter.
Background
Peritoneal dialysis is a variant of artificial blood purification, the peritoneum with good blood supply of a patient is used as a semipermeable membrane of the body, prepared dialysate is infused into the peritoneal cavity of the patient through a catheter by utilizing the action of gravity, so that the solute on one side with high concentration can move to one side with low concentration (diffusion effect) due to the concentration gradient difference of the solute on the two sides of the peritoneum, moisture can move from one side with low concentration to one side with high concentration (osmosis effect), and the dialysate in the peritoneal cavity is continuously replaced so as to achieve the purposes of removing in-vivo metabolites and toxic substances and correcting water and electrolyte balance disorder.
Peritoneal dialysis has a good effect of protecting residual renal function, is one of effective methods for renal function replacement treatment of patients with renal failure (uremia) confirmed by the medical community, and factors influencing peritoneal dialysis comprise: solute concentration gradient, dialysate volume and flow rate, effective area of peritoneum, peritoneal fluid residence time, glucose concentration in dialysate, dialysate temperature.
The existing peritoneal dialysis catheter usually adopts a straight tube type dialysis catheter, and in the dialysis process, the peritoneal dialysis catheter needs to be kept in place for a long time so as to communicate the inside and outside of an abdominal cavity for liquid exchange. However, the straight dialysis tube has poor sealing performance, so that the dialysate leaks along the skin incision, which may affect the dialysis efficiency and even cause serious consequences such as bacterial infection.

the dialysis tube is communicated with a bag capable of expanding, and the outer wall of the bag is attached to the fixed shell;
the diameter of the upper port of the fixed shell is smaller than that of the lower port of the fixed shell, and the fixed shell is fixed with the skin through an adhesive tape;
the fixed shell is formed by encircling four plates I and four plates II along the axis;
the first plates are arranged along four directions, and a plurality of the first plates are arranged;
the two plates are respectively arranged between two adjacent first plates and are attached to the opposite wall surfaces of the two first plates, so that a fixed shell is formed;
the fixed tube is fixed with one surface of the second plate facing the skin, connecting rods are arranged on the outer wall surface of the fixed tube along four directions, and the four connecting rods are connected with the first four plates through shafts.
Advantageous effects
When dialysate flows through the bag, the bag expands towards the periphery, one end of the first push plate, which is close to the skin, gathers towards the opening, and the skin around the opening is driven to generate certain displacement through the adhesive plaster, so that the skin abuts against the fixed tube, and the dialysate in a body can be prevented from permeating out along the opening of the skin during injection or discharge to cause infection to the opening.
