First Claim
1. An assembly for the preparation of solutions for human administration comprising:
- a first bag which retains water therein;
a mixing bag in communication with the first bag;
a first valve for controlling the admission of water from the first bag to the mixing bag;
an electric eye positioned to detect the level of the contents within the mixing bag and a controller which halts the introduction of water when the electric eye detects water reaching the desired level;
portions of the mixing bag defining an inlet opening for the introduction of medicament holders into the mixing bag;
a second bag in communication with the mixing bag;
a filter positioned between the mixing bag and the second bag; and
a second valve positioned between the mixing bag and the filter, for controlling the admission of a solution to the filter.

Abstract
Robotic manipulation of three-part plastic preparation assemblies automatically produces IV solutions which conform to a input specifications of a pharmacist located on site or remotely, including preparation telerobotically. The transparent plastic bag assemblies are stored in a magazine, and are extracted automatically one by one for preparation of individual prescriptions. A supply bag is prefilled with U.S.P. water and is connected through a valve to a mixing bag. Unit dose holders with medicaments and pH adjusting chemistries are dispensed into the mixing bag through an inlet where they are broken open by manipulation, and water is introduced. The bag contents are mixed by rotation of a magnetic mixing bar. The mixing bag is connected by a second valve through a filter to an administration bag. Negative pressure is applied to the administration bag to draw the solution through the filter. The administration bag is then heat sealed and severed from the filter for delivery to the patient. For ophthalmic solutions, a plurality of pre-capped containers are formed on the administration bag, and liquid from the administration bag is drawn into the individual ophthalmic solution containers, which are then heat sealed and severed from the administration bag.

a resilient air container filled with pressurized air;
a first compartment in communication with the air container;
a second compartment in communication with the first compartment, wherein portions of the second compartment define a weakened line of plastic material;
a unit dose of medicament contained in the second compartment; and
at least one rupturable barrier between the air container and the first compartment, wherein external pressure applied to the air container causes the pressurized air contained therein to rupture the barrier and the weakened line of plastic material and thereby discharge the unit dose of medicament from the unit dose holder.
