ASSEMBLY TO FACILITATE USER RECONSTITUTION
First Claim
1. A reconstitution assembly comprising:
- (a) a housing having a generally cylindrical shape;
(b) a first container disposed within the housing and configured to be axially displaced relative to the housing, the first container having a first opening sealed with a first seal cap;
(c) a second container disposed within the housing having a second opening sealed with a second seal cap, wherein the first container is arranged within the housing coincident to the second container;
(d) a transfer set assembly disposed within the housing and between the first container and the second container, the transfer set assembly configured to fluidly access first contents through the first seal cap of the first container and fluidly access second contents through the second seal cap of the second container; and
(e) a triggering mechanism configured to ensure that the first contents of the first container are accessed by the transfer set assembly before the second contents of the second container are accessed by the transfer set assembly, the triggering mechanism having a base portion engaged with the second container and a plurality of fingers extending from the base portion, the triggering mechanism operable in an unactivated state and an activated state, wherein;
(i) in the unactivated state, the plurality of radially spaced figures engage with the housing to prevent axial displacement of the second container relative to the housing and the transfer set assembly; and
(ii) in the activated state;
(1) first, the first container is axially displaced relative to the housing and the transfer set assembly so that the transfer set assembly pierces the first seal cap to access the first contents, the first container then causing the trigger fingers to disengage from the housing after the transfer set assembly has accessed the first contents, and(2) second, the second container is axially displaced relative to the housing and the transfer set assembly so that the transfer set assembly pierces the second seal cap to access the second contents.

Abstract
A reconstitution assembly includes a housing including a lower sleeve and an upper sleeve, including a first container and a second container disposed vertically opposite the first container. A transfer set assembly is disposed within the housing between the first container and the second container. The transfer set assembly includes an upper spike housing and a lower spike housing, with a flow path defined through the upper spike housing and the lower spike housing. The transfer set assembly is configured to access contents of the first container and then upon the activation of a triggering mechanism, create a fluid pathway between the first container and the second container. The triggering mechanism includes trigger fingers which ensure the transfer set assembly sequentially accesses the contents of the first container before accessing the contents of the second container. The disposition of the first container activates the triggering mechanism.

18. A reconstitution assembly for reconstituting a medication contained in a first container with a diluents contained in a second container, the first container including a first opening sealed with a first penetrable seal cap, the second container including a second opening including a second penetrable seal cap, the assembly comprising:
-
(a) a housing forming a passageway, at least a portion of the first container disposed within the passageway, the housing moveably retaining the first container in a first resting position, at least a portion of the second container disposed in the passageway, the first and second containers arranged such that the first opening of the first container faces the second opening of the second container; (d) a transfer set assembly attached to the housing and positioned between the first container and the second container, the transfer set assembly including a first spike extending toward the first penetrable seal cap and a second spike extending toward the second penetrable seal cap, the assembly forming a flow path extending through at least a portion of the first spike and a portion of the second spike, the first spike not penetrating the first seal cap when the first container is in the first resting position; (c) a triggering mechanism configured to engage the second container and including a plurality of fingers extending within the passageway to releasably engage the housing and maintain the second container in a second resting position with the second seal cap not penetrated by the second spike, the fingers configured to be engaged by the first container after the first container moves past a first activated position with at least a portion of the first spike penetrating the first seal cap to establish fluid communication between the interior of the first container and the flow path, the engagement of the first container to the fingers disengaging the fingers from the housing sufficiently to allow the second container to move toward the first container to a second activated position with at least a portion of the second spike penetrating through the second seal cap to establish fluid communication with the flow path. - View Dependent Claims (19, 20, 21, 22)

23. A method for reconstituting a medication comprising reconstitution assembly comprising:
-
placing a housing in a first orientation, the housing forming a passageway and at least a portion of a first container disposed within the passageway with an end of the first container extending outward from a first rim of the housing, at least a portion of a second container disposed in the passageway with an end of the second container extending outward from a second rim of the housing, the first and second containers arranged such that a first seal cap sealing an opening of the first container faces a second seal cap sealing an opening of the second container, a transfer set assembly positioned between the first container and the second container, the transfer set assembly including a first spike extending toward a first seal cap and a second spike extending toward a second seal cap, the transfer set assembly forming a flow path extending within the spikes and including a withdrawal port that extends through a side of the housing; placing the second end of the second container against a surface; exerting a force against the first end of the first container, the force moving the first container toward the transfer set assembly at least until the first spike penetrates a first seal cap of the first container sufficiently to place the flow path in fluid communication with an interior of the first container, preventing movement of the second container toward the transfer set assembly at least until fluid communication is established between the flow path and the interior of the first container, at least after the fluid communication is established between the flow path and the interior of the first container, the force moving the second container toward the transfer set assembly at least until the second spike pierces a second seal cap of the second container sufficiently to place the flow path and an access pathway formed by the transfer set assembly in fluid communication with the interior of the second container; flowing a fluid in the first container into the second container through the flow path; mixing the fluid with medication contained within the second container to form a reconstituted medication; and withdrawing the reconstituted medication through the access pathway and withdrawal port, while portions of the first and second containers remain within the passageway and the first and second seal caps remain pierced by the transfer set assembly.
