Pressure-activated medication transfer system
First Claim
1. A connector for effecting pressurized communication between a pressurizable diluent container and a drug vial through respective openings sealed by respective penetrable stopper means, comprising:
- (a) a base;
(b) a drug spike extending from said base in a first direction and having an axially extending drug bore open at its distal end;
(c) a diluent spike extending from said base in a second direction opposite said first direction and coaxially with said drug spike, said diluent spike having an axially extending diluent bore open near its distal end and communicating at its proximal end with the proximal end of said drug bore through said base;
(d) means for sealingly fastening said base against the respective openings of said drug vial and said diluent container when said drug spike and said diluent spike are thrust through the respective penetrable stopper means of said vial and said container; and
(e) a plug seated in and sealing one of said bores, said plug being disposed completely within said bore and being expellable from said sealed bore when said diluent container is pressurized.

Abstract
A binary connector intercouples a plugged drug vial and a plugged, flexible-walled diluent container so that the diluent can pass to the vial from the container only after the latter has been pressurized by squeezing. Sharp-tipped, hollow spikes with intercommunicating axial bores extend in diametrically opposite directions from a disk-shaped base, with jaws having circularly arrayed flexible arms extending in diametrically opposite directions from the base, coaxially around respective ones of the spikes. A compressible rubber plug is wedged in one of the bores. A vial is engaged to a container for liquid communication by snapping the connectors'"'"' jaws around their respective inlets, causing the connectors'"'"' hollow spikes to pierce their respective plugs. However, not until the container is squeezed is the plug expelled from the blocked bore and communication established between vial and container.
