DISPOSABLE FOR A DEVICE FOR CARRYING OUT A MEDICAL TREATMENTUSING A FLUID

摘要

The invention relates to a disposable element for a medical treatment device , especially a hemodialysis device. The inventive disposable element comprises a film bag filled with the dialysis liquid that consists of two superimposed flat films or a tubular film with connections for supplying and discharging the liquid. The film bag or the tubular film, in the condition ready for usage, is closed with a first weld on the top end and with a second weld (4, 5) on the lower end and is folded several times parallel to the longitudinal axis that is vertical in the condition ready for usage. The film bag is inserted in a receiving unit that is configured as a shaping dish (15) that has a middle cylindrical section (16) followed by an upper or lower convex section (17, 18). The inventive disposable element, when combined with the receiving unit, unfolds more easily when being filled and has a lesser tendency to form creases.
