the developer bag so as to seal the opening in the developer bag, and when the unsealing member, which is supported rotatably inside the developer storage unit, rotates, the sealing member is wound up so as to be peeled away from the developer bag.
The developer stored in the developer bag is discharged through the opening when the opening is opened, and supplied to the developing roller via the developer supply roller. By inserting the developer bag filled with the developer into the developer storage unit and opening the developer bag within the developer storage unit, the developer can be prevented from scattering when the developer is charged into the developer storage unit (Japanese Patent Application Publication No. 2013-037347, FIG. 1).concentration (diffusion) between the dialysis fluid and the blood, substances dissolved in the plasma water, in particular substances with a higher molecular weight, are effectively removed during hemofiltration (HF) by a high fluid stream (convection) through the membrane of the dialyser. During hemofiltration, the dialyser acts as a filter. Hemodiafiltration (HDF) is a combination of the two methods.
In hemo(dia)filtration part of the serum withdrawn through the membrane is replaced by a sterile substitution fluid which is passed to the extracorporeal blood stream either upstream of the dialyser or downstream of the dialyser. The supply of substitution fluid upstream of the dialyser is also referred to as predilution, and the supply downstream of the dialyser is also referred to as postdilution.
Devices for hemo(dia)filtration are known in the case of
