Cartridge and adapter for introducing a beneficial agent into an intravenous delivery system
First Claim
1. An adapter for placing an intravenous delivery system including a fluid source, a fluid conduit and a receptacle in the fluid conduit, in fluid communication with a chamber having a beneficial agent therein, said adapter defining flow path means between the receptacle and the chamber and comprising:
- (a) a rigid cannula having an inlet and an outlet;
(b) a shell spaced from said cannula intermediate of said cannula inlet and said cannula outlet, with said cannula and said shell defining a channel therebetween, about the exterior of said cannula, said channel including a channel inlet short of said cannula outlet and a channel outlet short of said cannula inlet;
(c) cannula holder means secured to said cannula;
(d) extension means extending between said cannula holder and said shell and securing said cannula relative to said shell, there being an open flow path through said channel, including said channel inlet and said channel outlet;
(e) wherein said channel inlet and said cannula outlet are both adaptable to pierce a single opening in a first injection site, associated with the receptacle of the delivery system; and
(f) wherein said channel outlet and said cannula inlet are both adaptable to pierce a single opening in a second injection site, associated with the chamber.

20. An adapter for placing an intravenous delivery system including a fluid source, a fluid conduit and a receptacle in the fluid conduit, in fluid communication with a chamber having a beneficial agent therein, said adapter defining flow path means between the receptacle and the chamber and comprising:
-
(a) hollow rigid tube means; (b) a plate mounted within said tube, transverse of the tube length; (c) a rigid cannula extending through said plate within said hollow tube, said rigid cannula having an inlet on one side of said plate and an outlet on the other side of said plate; (d) a shell extending from said plate and spaced from said cannula intermediate of said cannula inlet and said cannula outlet, said cannula and said shell defining a channel therebetween, about the exterior of said cannula, said channel including a defined channel inlet on the same side of said plate as said cannula outlet and a defined channel outlet on the same side of said rigid plate as said cannula inlet; (e) cannula holder means secured to said cannula; (f) extension means extending between said cannula holder and said shell and securing said cannula relative to said shell, there being an open flow path through said channel, including said channel inlet and said channel outlet; (g) wherein said channel inlet and said cannula outlet are both adaptable to pierce a single opening in a first injection site, associated with the receptacle of the delivery system; and (h) wherein said channel outlet and said cannula inlet are both adaptable to pierce a single opening in a second injection site, associated with the chamber. - View Dependent Claims (21, 22, 23, 24, 25, 26)
