Abstract
A dialysis machine for the removal of toxic substances from biological fluids with agents for the decalcification of a dialysis liquid circulation is disclosed. The dialysis machine allows measurement of the degree of calcification of the dialysis liquid through the use of a blood leak detector or by measuring the dialysis machine pump flow or pump voltage. The invention also includes a process for automatically decalcifying the dialysis liquid circulation when a predetermined degree of calcification of the dialysis machine is measured.
Claims14
A dialysis machine for the removal of toxic substances from biological fluids having a means for decalcification of the dialysis machine, a means for determining the degree of calcification of the dialysis machine, and a means for automatically initiating decalcification of the dialysis machine as a function of the degree of calcification of the dialysis fluid.
A method for automatically decalcifying a dialysis machine comprising the steps of:
- (a) determining the degree of calcification of the dialysis machine;
- and
- (b) automatically initiating decalcification of the dialysis machine when the degree of calcification reaches a predetermined level.
