Adapter for passive drug delivery system
First Claim
1. An adapter adapted to connect with a drug vial for introducing a beneficial agent into a fluid conduit for delivery of the beneficial agent to a patient such that the beneficial agent may be passively reconstituted during fluid flow through the fluid conduit, said adapter and the drug vial, said adapter comprising:
- (a) a hollow, rigid shell including an enlarged end portion for connecting to the drug vial and an opposite end portion adapted for mounting about a receptacle, said adapter further providing for selective fluid communication between the receptacle and the drug vial;
(b) a sliding plate having a handle portion extending therefrom slidably mounted within said hollow rigid shell and including inlet flow path means and outlet flow path means mounted to said sliding plate, said inlet and outlet flow path means each further including drug vial piercing means extending from the sliding plate towards the enlarged end portion and receptacle piercing means extending from the sliding plate towards the opposite end portion;
wherein movement of said sliding plate enables sliding said flow path means towards said drug vial to pierce the drug vial, thereby placing the drug vial chamber, said inlet flow path means and said outlet flow path means in open communication; and
further wherein after said vial piercing means has pierced said vial chamber and said receptacle piercing means has pierced the receptacle, said inlet flow path means and said outlet flow path means each extend into the drug vial, with said outlet flow path means disposed at an elevation higher than said inlet flow path means.

6. An adapter adapted to connect with a drug vial for introducing a beneficial agent into a fluid conduit for delivery of the beneficial agent to a patient such that the beneficial agent may be passively reconstituted during liquid flow through the fluid conduit, said adapter and the drug vial, said adapter comprising:
-
(a) a hollow, rigid shell including an enlarged end portion for connecting to the drug vial and an opposite end portion adapted for mounting about a receptacle, said adapter further providing for selective liquid communication between the receptacle and the drug vial; (b) a sliding plate slidably mounted within said hollow rigid shell and including inlet liquid flow path means and outlet liquid flow path means mounted to said sliding plate, said inlet and said outlet liquid flow path means each further including drug vial piercing means extending from the sliding plate towards the enlarged end portion and receptacle piercing means extending from the sliding plate towards the opposite end portion, said outlet liquid flow path means being disposed away from the sliding plate a distance further than the inlet liquid flow path means both towards the enlarged end portion and towards the opposite end portion; wherein movement of said sliding plate enables sliding said liquid flow means towards said drug vial to pierce the drug vial, thereby placing the drug vial chamber, said inlet liquid flow path means and said outlet liquid flow path means in liquid communication; and further wherein after said vial piercing means has pierced said vial chamber and said receptacle piercing means has pierced the receptacle, said inlet liquid flow path means and said outlet liquid flow path means each extend into the drug vial, with said outlet liquid flow path means disposed at an elevation higher than said inlet liquid flow path means. - View Dependent Claims (7, 8, 9, 10, 11)
