Abstract

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 to 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 the 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 The resilient tube is self-recoverable over the sharpened end when the piston stopper is withdrawn.

Claims

1. An alimentation kit comprising:

(a) a plurality of cylindrical rigid vials, each having a closed end and cylindrical walls, and containing a liquid concentrate of an alimentary component, a slidable resilient piston stopper positioned approximately on the liquid surface within the vial and sealing same; and

(b) a transfer device for the sequential addition of the liquid contents of each of said vials to a glass bottle containing intravenous solution and provided with an imperforate closure, said transfer device having a cannula, said cannula having a central portion which is provided with an elongated longitudinally extending rigid cannula support having a length approximately equal to the length of said vials, in proximity to one end of said rigid cannula support a first laterally extending flange, one end portion of said cannula extending beyond said first laterally extending flange and being adapted to pierce the imperforate closure of said bottle containing intravenous solution, said first laterally extending flange being adapted to act as a stop to limit the extent of advancement of said cannula and to abut said imperforate closure of said bottle containing intravenous solution, in proximity to the other end portion of said rigid cannula support a second laterally extending flange which is circular in shape and slightly smaller in diameter than the interior of said cylindrical walls of said rigid vials, the other end portion of said cannula extending beyond said second laterally extending flange and terminating in a sharpened outer end, a thin resilient tube over said sharpened outer end, said resilient tube being closed in proximity to the sharpened outer end and along the length of said other end portion of said cannula and having an open end provided with an external integral ring which is received in a complementary annular female groove in the walls of an axial cylindrical recess in said other end of said rigid support to form a seal therewith, said second laterally extending flange being slidably engageable with the interior of said cylindrical walls and said resilient tube being longitudinally compressible over and pierced by said sharpened outer end when one of said vials is fitted over said second laterally extending flange and the piston stopper of said one of said vials is forced over said sharpened outer end, said resilient tube being constructed and arranged to act in its compressed state as a stop for said piston stopper while said vial is advanced over said other end portion of said cannula and said other end of said rigid support, whereby said piston stopper can be slidably moved to the closed end of said vial and all of the contents of the vial can be transferred to the bottle of intravenous solution through said cannula, said resilient tube being self-recoverable over said sharpened end when said piston stopper is withdrawn to maintain a seal over said cannula between the sequential additions of the liquid contents of each of said vials.
