Abstract
Abstract An additive transfer device for storing and transferring of a medicament to a solution container such as an I.V. bag having an exposed port. The transfer device includes a vial-type container having a slidable pierceable sealing element. A holder member secures a piercing cannular member and the holder has a guide means at one end to fit around th exposed port of the I.V. bag. A cover extends over the guide means and is in sealing contact with the vial. Activating means are provided in conjunction with the cover, the holder and the vial to effect movement of the holder member toward the vial and piercing of the vial stopper by one end of the cannula. With a piercing of the I.V. port by means of the other pointed end of the cannula, communication can be made between the additive container and the I.V. bag.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
232 words
An additive transfer device for storing and transferring of a medicament to a solution container having a pierceable closure comprising: an additive container for storing the medicament to be transferred, said additive container having rigid walls and a slidable, pierceable stopper in said container; a holder member; a piercing member having a channel therethrough for the flow of said medicament and a piercing point on both ends thereof, an intermediate portion of said piercing member secured by said holder member; guide means defined by said holder member, said guide means positioned from said piercing member and terminating inwardly of one end of said piercing member; a cover member adapted to extend over said holder member and said one end of said piercing member extending beyond said guide means; and said holder member and said additive container being interconnected to permit movement of said holder member and said piercing member toward said additive container; so that upon movement of said holder member and container said additive container will initially move over said holder member to effect a piercing of said additive container stopper and upon removal of said cover member and penetration of said solution container closure by the other piercing end of said piercing member, the contents of said additive container can be expelled into said solution container by further movement of said additive container over said stopper and said holder member.
Claim 2
Dependent Claim
232 words
An additive transfer device for storing and transferring of a medicament to a solution container having a pierceable closure comprising: an additive container for storing the medicament to be transferred, said additive container having rigid walls and a slidable, pierceable stopper in said container; a holder member; a piercing member having a channel therethrough for the flow of said medicament and a piercing point on both ends thereof, an intermediate portion of said piercing member secured by said holder member; guide means defined by said holder member, said guide means positioned from said piercing member and terminating inwardly of one end of said piercing member; a cover member adapted to extend over said holder member and said one end of said piercing member extending beyond said guide means; and said holder member and said additive container being interconnected to permit movement of said holder member and said piercing member toward said additive container; so that upon movement of said holder member and container said additive container will initially move over said holder member to effect a piercing of said additive container stopper and upon removal of said cover member and penetration of said solution container closure by the other piercing end of said piercing member, the contents of said additive container can be expelled into said solution container by further movement of said additive container over said stopper and said holder member.
Claim 3
Dependent Claim
21 words
The additive transfer device of claim 1 wherein the interconnection between said additive container and holder is comprised of complementary threading.
Claim 4
Dependent Claim
31 words
The additive transfer device of claim 2 wherein said activating means is further defined by means to substantially prevent rotary movement of said holder while permitting linear movement of said holder.
Claim 5
Dependent Claim
35 words
The additive transfer device of claim 3 wherein said means to substantially prevent rotary movement while permitting linear movement of said holder is defined by interfering rib members extending from said cover and holder members.
Claim 6
Dependent Claim
36 words
The additive transfer device of claim 3 wherein said means to substantially prevent rotary movement while permitting linear movement of said holder is defined by an interference fitment between said guide means and said cover member.
Claim 7
Dependent Claim
40 words
The additive transfer device of claim 5 wherein said interference fitment defined by said guide means and said cover member includes leg portions forming said guide means and parallel bar members extending from an end wall of said cover member.
Claim 8
Dependent Claim
31 words
The additive transfer device of claim 5 further including stop portions defined by said holder member and positioned adjacent the point of merger of said leg portions with said holder member.
Claim 9
Dependent Claim
21 words
The additive transfer device of claim 1 wherein said cover member and said vial are interconnected by a friction fit arrangement.
Claim 10
Dependent Claim
196 words
A ready-to-use, readily activated three component transfer device for storing and transfering of a medicament to a solution container having a projecting pierceable closure comprising: a medicament container for storing the medicament to be transferred with a pierceable stopper sealing said medicament in said medicament container; a holder member having secured thereto a piercing member with a channel therethrough for the flow of said medicament and a piercing point on both ends, said holder member defining guide means for surrounding said projecting pierceable closure and terminating inwardly of one end of said piercing member; and a cover member adapted to extend over said holder member and to engage said medicament container in a sealing manner, said cover member, said holder member and said medicament container defining together means to permit movement of said holder member and said other end of said piercing member toward said medicament container so that one of said piercing points of said piercing member will pierce said pierceable closure and provide a passage for flow of said medicament from said medicament container to said solution container when said other of said piercing points penetrates said projecting pierceable closure of said solution container.
Claim 11
Dependent Claim
196 words
A ready-to-use, readily activated three component transfer device for storing and transfering of a medicament to a solution container having a projecting pierceable closure comprising: a medicament container for storing the medicament to be transferred with a pierceable stopper sealing said medicament in said medicament container; a holder member having secured thereto a piercing member with a channel therethrough for the flow of said medicament and a piercing point on both ends, said holder member defining guide means for surrounding said projecting pierceable closure and terminating inwardly of one end of said piercing member; and a cover member adapted to extend over said holder member and to engage said medicament container in a sealing manner, said cover member, said holder member and said medicament container defining together means to permit movement of said holder member and said other end of said piercing member toward said medicament container so that one of said piercing points of said piercing member will pierce said pierceable closure and provide a passage for flow of said medicament from said medicament container to said solution container when said other of said piercing points penetrates said projecting pierceable closure of said solution container.
