Controlled access mixing vial
First Claim
1. A controlled access mixing vial, for use with first and second pharmaceutical components, the second component being a liquid component, comprising:
- a mixing container having first and second ends with openings at the first and second ends;
a septum mounted to and sealing the first end of the mixing container;
a breachable seal at the opening at the second end of the mixing container, the first component being within a mixing region between the seal and the septum;
a supplemental container;
the mixing and supplemental containers being coaxially translating containers with the second end of the mixing container sealably positioned within the supplemental container, the second component being within a variable volume region defined by the mixing and supplemental containers;
a first rotary drive element associated with and covering the first end of the mixing container;
a second rotary drive element associated with the supplemental container;
thread means for rotationally coupling the first and second rotary drive elements so that rotating the first and second drive elements in a first rotary direction from an initial rotary orientation to a final rotary orientation drives the mixing container into the supplemental container from a pre-mixed condition to a post-mixed condition to force the second component past the breachable seal and into the mixing region causing the first and second components to mix to create a mixed pharmaceutical;
a first rotary lock operably coupling the first and second rotary drive elements when in the initial rotary orientation and preventing rotary movement except in the first rotary direction when in the initial rotary orientation; and
a second rotary lock operably coupling the first and second drive elements when in the final rotary orientation and preventing any relative rotary movement therebetween when in the final rotary orientation.

Abstract
A controlled access mixing vial (2) includes a cylindrical mixing container (8) having a fixed septum (14) at its outer end (10) and a breachable seal (22) at its inner end (12). A first pharmaceutical (52) is housed within the mixing container between the seal and the septum. A supplemental container (4) is coaxially translatably mounted to the mixing container and contains a second pharmaceutical (50) between the mixing and supplemental containers. Collapsing the mixing and supplemental containers from a pre-mixed condition to a post-mixed condition, preferably with a chosen rotary movement (128, 130) using threads (60, 62), causes the breachable seal to open permitting the second pharmaceutical to be driven into the mixing container. Movement to the post-mixed condition dislodges a safety shield (100) to permit access to the septum. Rotary locks (116, 118, 120) limit movement from the pre-mixed condition except with the chosen rotary movement and prevents all movement from the post-mixed condition.
