ARTIFICIAL KIDNEY HYDRAULIC SYSTEM INCLUDING A DIALYSIS LIQUID FILTRATION APPARATUS

摘要

a hydraulic circuit for an artificial circuit, is provided for in this.kidneymachine with a pipe for liquid supply.with athe first portion is connected to a source of a bank of fluiddialysis andthe second portion has one end connected to a hu00e9modialyseur or acircuit forextracorporeal circulation of blood. the circuit also includes aultrafiltre witha first and a second chamber separated by a membrane capable of retainingthemicrobial components and pyrogens, the first portion of the conduitfoodwith its other end connected to a gate of the first chamber and theseconda portion of the feed pipe is connected with the other endto exitthe second chamber. the circuit also includes means for determiningthein the ultrafiltre transmembrane pressure, how to bypass forconnectthe first and second portions of the power line andbanpassage of fluid in the ultrafiltre, and drive means to comparethetransmembrane pressure measured at at least one threshold value, andorderwhen the measured value of shunt means reaches the threshold value.as thefirst and second portions of the supply pipeline is connecteddirectly.the liquid passage is banned in the ultrafiltre.
