SET OF DEVICES FOR PERITONEOFILTRATION AND THE USAGE OF IT

摘要

The invention refers to a set of devices used in the peritoneum filtration, a new medical method which replaces the hemodialysis, the peritoneal dialysis, hemodiafiltration and hemofiltration. The set of devices for the peritoneum filtration, according to the invention, has in its structure : a double lumen catheter (1) type balloon, in which the two lumens, after a common proximal part, is separated in a bifurcation in two branches (2, 3), which are chirurgical located in the right suprahepatic vein and right porta vein and through the variable diameter of the balloon (8) determines the controlled obstruction of these veins; close to each end further from de balloons 8, is located one of the preussure sensors (4, 5) which permanently measure the pressure from the cathetered veins and transmits the information to a command modulus (9); a command modulus (9) which monitors and controls the pressure from the catheterized veins, is in direct link with the proximal end of the double -lumen catheter (1), is subcutaneous implanted in the right under the clavicle area and it is programmed to action at the modifications of pressure detected by the pressure sensors (4, 5); a vesicle device through which the liquid accumulated in the abdomen gravitationally lowers into the urinary bladder and is chirurgical implanted at the level of the superior cap of the urinary bladder, device which is made of a action module, action from exterior through a remote and a vesicle element situated above the modulus. The method for the peritoneum filtration using the set of devices according with the invention, consists of an internal double obstruction of the right suprahepatic veins and of the right branch of the porta vein through introducing in these veins of the two branches 3 and 4 of the double lumen catheter balloon type, the narrowing done by the balloons (8) being permanent,with maximum of 50% stenosis, in concordance with the pressure from the suprahepatic veins, minitored by the system, portal hypertension being maintained between the limits of 12-18 mmHg through double adjustment of the two obstructions and the possibility to monitor by the command modulus 9 of the quantity of ascites obtained in the abdomen.
