<p>R An alimentation kit comprising a plurality of cylindrical rigid vials, each containing a liquid concentrate of an alimentary component and a resilient slidable sealing piston stopper within the vial. The kit also includes a transfer device for the sequential addition of the liquid contents of each of said vials to a conventional container of intravenous solution. The transfer device has a cannula which is provided with a longitudinally extending rigid support, in proximity t one end of the rigid support a laterally extending flange, the laterally extending flange being adapted to act as a stop to limit the extent of advancement of the cannula. The other end portion of the cannula extends beyond the other end of said rigid support and terminates in a sharpened outer end. A thin resilient tube is provided over sharpened outer end. The resilient tube is longitudinally compressible over and pierced by the sharpened outer end when the piston stopper of one of the vials is forced over the sharpened outer end whereby the contents of the vial can be transferred to the intravenous solution container through the cannula. The resilient tube is self-recoverable over the sharpened end when the piston stopper is withdrawn.</p> |
