Abstract

Various embodiments of an improved reconstitution device 30, 168, 170, 186, 242, 256, 274 are disclosed, directed to the proper mixing of two substances, and are particularly directed to the medical field for the reconstitution of a drug 36 which may be stored in a drug vial 32 with a diluent 60 stored in a flexible medical solution container 34 and used for the intravenous delivery of a medicament. In one embodiment the reconstitution device 30 includes an improved vial adapter 76 and bag adapter 78 which permit the permanent coupling of the vial 32 and liquid container 34. The bag adapter 78 may be rotatable relative to the vial adapter 76 to operate a valve including a stem channel 108 and a base post 148 on the vial adapter 76, a base segment channel 136 and a cut out portion 146 of a rim 140 on the bag adapter 78, and a sealing segment 80 disposed between the vial and bag adapter 76, 78. The reconstitution device 30 reduces drug waste in hospitals, eliminates the need to relabel parenteral solution containers after a drug has been added, and prevents repeated exposure of hospital personnel to various drugs.

Claims

1. A reconstitution device comprising:

(a) means for securing said reconstitution device to a drug container defining a chamber, including a pierceable, self-sealing access site, said drug container securing means comprising;

(i) base means secured to flow path means,

(ii) at least two upstanding wall portions extending from said base means, each wall portion having a top, said wall portions being spaced from each other to permit bending of said wall portions toward and away from each other,

(iii) a ridge extending inwardly from an inside wall of at least one of said wall portions, near said top, and

(iv) a wall slot in each of said wall portions having an annular ridge, each of said wall slots extending from said base means to said annular ridge, whereby said drug container securing means includes an interlock to prevent inadvertent removal of said reconstitution device from the drug container;

(b) liquid container piercing means operatively secured to said flow path means for piercing a pierceable self-sealing injection site of a flexible walled medical liquid container defining a chamber;

(c) drug container piercing means operatively secured to said flow path means for piercing the access site of the drug container;

(d) flow path means secured to said base means for placing the chamber of the drug and liquid containers into open communication; and

(e) a liquid container adapter having at least one wall segment extending from said base means and being disposed around and spaced from at least a portion of the flow path means, wherein said flow path means comprises a needle, said device further comprising a cup removably mounted in said liquid container adapter, said cup including an opening in the end thereof through which said needle extends, said cup being adapted for retention on the injection site of the liquid container, even after removal of said reconstitution device therefrom.

2. A reconstitution device comprising:

(a) base means;

(b) means for securing said reconstitution device to a drug container defining a chamber and including a pierceable, self-sealing access site, said drug container-securing means being secured to said base means;

(c) drug container piercing means for piercing the access site of the drug container;

(d) liquid container piercing means for piercing a pierceable self-sealing injection site of a flexible-walled medical liquid container defining a chamber;

(e) flow path means secured to said base means, for placing the chambers of the drug and liquid containers into open communication after the access site and the injection site have been pierced by said piercing means, wherein said flow path means comprises a needle and is operatively secured to both said piercing means;

(f) a liquid container adapter having at least one wall segment extending from said base means and being disposed around and spaced from a portion of the flow path means; and

(g) a cup removably mounted in said liquid container adapter and including a defined opening in the end thereof through which said needle extends, said cup being adapted for retention on the injection site of the liquid container, even after removal of said reconstitution device therefrom.
