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.

A system for filling multiple sterile containers includes a filter with an inlet port and multiple outlet ports, the outlet ports being pre-attached to sterile containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines are connected to a respective container interior. The respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. A container that is connectable to an outlet port the system has a bladder, a first tube and a second tube connected to the bladder, and a sterilizing filter. The container, the first tube and the second tube, and the sterilizing filter are sterile before water is flowed through the sterilizing filter into the bladder.

This invention relates to a new and improved hydraulic squeeze tool for compressing and stopping flow through a lay flat or poly hose, such invention engineered to increase the speed and efficiency when cutting flow and fluid transfers in pipe and hose systems in domestic, commercial, or heavy industrial applications.

For producing a high pressure impulse, a hose bending valve is provided that comprises a loop (12) provided in a supply hose of an instrument (2) and a hose bending device (8) provided as multiple-use component. Such a valve is very simply constructed and allows the creation of steep pressure increase flanks with very high pressures up to 100 bar, as are needed for a needleless injection. The sterilization effort is minimal. Also, the material effort is minimal, if single-use components are used.
