Filtration system for preparation of fluids for medical applications

摘要

Systems, methods, and devices for preparation of purified water and medicaments for various uses including blood treatment are described. Methods, devices, and systems for creating multiple-treatment batches are described. For example, a medicament fluid circuit can include a container with an interior chamber. The container can have a fluid filling port and a fluid extraction port. Both ports can be connected to the interior chamber. The filling port can have two sterilizing filters, each of which has a membrane. The sterilizing filters can be connected in series the membranes are separated by a distance of at least 0.5 cm. A first of the sterilizing filters can have a sealed inlet. The fluid extraction port can be sealed.

1. A fluid circuit, comprising:
a sterile medical liquid supply containing a sterile medical liquid and having a pump configured to convey the sterile medical liquid at a predefined flow rate; a sterile medical liquid container made of a flexible film with
an interior chamber, andan inlet connected to receive the sterile medical liquid from the sterile medical liquid supply at said predefined flow rate;an inlet liquid line directly connected to the sterile medical liquid supply receiving the sterile medical liquid conveyed by the pump; andan outlet liquid line connected to the interior chamber;at least the inlet liquid line being further connected to a flexible tube extending into the interior chamber, whereinthe flexible tube has a fixed end and a free end separated by a predefined length, andthe flexible tube connected to the inlet liquid line is caused to whip around inside the interior chamber by the sterile medical liquid flowing through the flexible tube at the predefined flow rate.
