Medicinal fluid delivery device
In some embodiments, a reconstitution or medicinal fluid delivery device includes a transfer engine including two fluidly connected spikes, each configured to pierce a container. A check valve may be disposed between the two spikes to allow unidirectional flow from one container to the other. Physical access to a fluid outlet may be obstructed by a housing until the reconstitution or medicinal fluid delivery device is actuated, whereupon physical access to the fluid outlet is permitted. The reconstitution or medicinal fluid delivery device may be placed on a flat surface and actuated with force applied in a single direction toward the flat surface.
1 . A reconstitution device comprising;
a first spike extending from a first base piece;
a second spike extending from a second base piece, wherein said first and second base pieces are coupled to one another via an interlocking arrangement;
an inlet in fluid communication with the first spike;
an outlet in fluid communication with the second spike;
a fluid pathway leading from the first spike to the second spike; and
a housing circumscribing the first base piece and the second base piece.
2 . The reconstitution device of claim 1 , wherein said first and second base pieces are coupled to one another via an intermediate piece.
3 . The reconstitution device of claim 1 , wherein the first base piece and second base piece are attached directly to each other.
4 . The reconstitution device of claim 2 , further comprising a third spike coupled to the intermediate piece.
5 . The reconstitution device of claim 1 , further comprising a check valve positioned in the fluid pathway.
6 . The reconstitution device of claim 1 , wherein the inlet is an air inlet.
7 . The reconstitution device of claim 1 , further comprising a hydrophobic filter at the inlet.
8 . The reconstitution device of claim 1 , further comprising:
a first sheath covering at least a portion of the first spike; and
a second sheath covering at least a portion of the second spike.
9 . The reconstitution device of claim 1 , wherein the housing has a lower portion and an upper portion in movable engagement with the lower portion, the upper portion being movable relative to the lower portion from an unactuated position and an actuated position.
10 . The reconstitution device of claim 9 , further comprising a first container aligned with the first spike and a second container aligned with the second spike, wherein the first spike is configured to spike the first container and the second spike is configured to spike the second container when the upper portion of the housing is moved to the actuated position.
11 . The reconstitution device of claim 10 , wherein the second container contains a vacuum such that fluid in the first container is at a higher pressure than a pressure of an interior of the second container.
12 . The reconstitution device of claim 9 , wherein the outlet is movable relative to the housing.
