HEMODIALYSIS APPARATUS

摘要

A hemodialysis apparatus comprises an inlet (BA) for blood from an arterial outlet, such as an arterial catheter/cannula outlet, an outlet (BB) for treated blood to a venous inlet, such as a venous catheter/cannula inlet, a blood flow path with a blood pump (9), at least one pressure gauge (5, 6) for monitoring the blood pressure, at least one air detector (7) for detecting air in the blood path, and further an artificial kidney or filtration means (14) for the blood from the blood inlet (BA) to the apparatus, and at least one dialysis path connected to the outlet of the artificial kidney or filtration means and a receiver (DM) for the dialysate. In a known manner per se the blood pump (9) is infinitely variable, while in the dialysis path there is at least one dialysis pump (10; 11), which is infinitely variable. The pump rate for the first dialysis pump (10) is adjusted to perform a predetermined withdrawal volume rate from the outlet from the artificial kidney or filtration means (14). The other dialysis pump (11) is adjusted to perform a predetermined volume rate of fresh or cleansed dialysate to the dialysis inlet of the artificial kidney or filtration device (14).
