Abstract
Abstract A sterile container for a medicinal material which is to be intermixed in an I.V. solution wherein the container serves as a mixing device as well as a portion of an I.V. administration apparatus. The device of this invention includes a container which is closed at opposing ends by pierceable diaphragm portions. Extending from one end is a piercing pin having a diaphragm piercing portion which can pierce the diaphragm when it is moved inwardly into the container and also provide a fluid passageway for the container contents. At the opposing end a diaphragm is housed in a closure with a tubular guide section for the piercing pin of an I.V. administration set. The container therefore serves a dual function of holding a fluid material such as a powder in a sterile condition yet serving as a component of an I.V. set to thereby afford a quick and simple procedure for mixing additive components into an I.V. administration set.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
212 words
An in-line transfer unit for mixing a sterile fluid material from a first container into a second container with the contents of both containers to be subsequently delivered through said second container, said unit comprising; a container having opposing passageways for storing a fluid material to be transferred; first and second closures sealing the passageways in said container, said closures defined in part by pierceable diaphragm portions; a transfer member having a passage therethrough with a piercing end on one end and a diaphragm piercing portion on the other end; retentive movement means operatively associated with said first closure and said transfer member to permit sufficient movement of said transfer member so that said piercing portion thereof can pierce said diaphragm of said first closure; so that when the piercing end of the transfer member is in fluid communication with said first container, said diaphragm piercing portion can be moved to pierce said diaphragm portion of said second container and permit intermixing of the material therein with the contents of said first container, and subsequently, the opposing diaphragm portion of said second closure will be pierced by another piercing member and the contents of both containers will flow through and out of said second container by means of said other piercing member.
Claim 2
Dependent Claim
212 words
An in-line transfer unit for mixing a sterile fluid material from a first container into a second container with the contents of both containers to be subsequently delivered through said second container, said unit comprising; a container having opposing passageways for storing a fluid material to be transferred; first and second closures sealing the passageways in said container, said closures defined in part by pierceable diaphragm portions; a transfer member having a passage therethrough with a piercing end on one end and a diaphragm piercing portion on the other end; retentive movement means operatively associated with said first closure and said transfer member to permit sufficient movement of said transfer member so that said piercing portion thereof can pierce said diaphragm of said first closure; so that when the piercing end of the transfer member is in fluid communication with said first container, said diaphragm piercing portion can be moved to pierce said diaphragm portion of said second container and permit intermixing of the material therein with the contents of said first container, and subsequently, the opposing diaphragm portion of said second closure will be pierced by another piercing member and the contents of both containers will flow through and out of said second container by means of said other piercing member.
Claim 3
Dependent Claim
39 words
The in-line transfer unit as defined in claim 1 wherein said closures sealing the passageways in the containers are defined by guide members for said transfer member and said other piercing member with said diaphragm portions placed inwardly therein.
Claim 4
Dependent Claim
39 words
The in-line transfer unit as defined in claim 2 wherein said second closure is defined by a wall portion extending outwardly and spaced from said guide member, said wall portion providing securing means to receive a removable cap member.
Claim 5
Dependent Claim
38 words
The in-line transfer unit as defined in claim 3 wherein said first closure includes an outwardly extending wall portion and spaced from said guide member, said wall portion defining said retentive movement means for said associated transfer member.
Claim 6
Dependent Claim
37 words
The in-line transfer unit as defined in claim 4 wherein said transfer member associated with said first closure includes means integrally associated therewith to vent said first container when said transfer member is in fluid communication therewith.
Claim 7
Dependent Claim
27 words
The in-line transfer device as defined in claim 3 wherein said first closure is formed separately from said container and said second closure is formed integrally therewith.
Claim 8
Dependent Claim
19 words
The in-line transfer device as defined in claim 6 wherein said container is formed from a flexible wall member.
Claim 9
Dependent Claim
35 words
The in-line transfer device as defined in claim 2 wherein said guide members are defined by tubular members and include internal frictional engagement ribs for contact with said transfer member and said other piercing member.
Claim 10
Dependent Claim
23 words
The in-line transfer device as defined in claim 2 wherein said other piercing member comprises a portion of an intravenous solution administration set.
Claim 11
Dependent Claim
164 words
A container for the sterile fluid material which can be later interconnected into an intravenous solution administration set including a solution container to administer the fluid material thereby, comprising: a substantially cylindrical container having opposing openings for storing a fluid material to be transferred; first and second closures sealing the openings in said container, said closures defined in part by integrally formed pierceable diaphragm portions; a transfer member in the form of a channeled piercing pin having a diaphragm piercing portion at one end; and means operatively associated with said first closure and said transfer member to permit movement of said transfer member so that said diaphragm piercing portion can pierce said diaphragm portion of said cylindrical container and permit intermixing of the fluid material therein with the contents of said solution container, and subsequently, the opposing diaphragm portion of said second closure will be pierced by another piercing pin member and the contents of both containers will be administered by said administration set.
Claim 12
Dependent Claim
164 words
A container for the sterile fluid material which can be later interconnected into an intravenous solution administration set including a solution container to administer the fluid material thereby, comprising: a substantially cylindrical container having opposing openings for storing a fluid material to be transferred; first and second closures sealing the openings in said container, said closures defined in part by integrally formed pierceable diaphragm portions; a transfer member in the form of a channeled piercing pin having a diaphragm piercing portion at one end; and means operatively associated with said first closure and said transfer member to permit movement of said transfer member so that said diaphragm piercing portion can pierce said diaphragm portion of said cylindrical container and permit intermixing of the fluid material therein with the contents of said solution container, and subsequently, the opposing diaphragm portion of said second closure will be pierced by another piercing pin member and the contents of both containers will be administered by said administration set.
Claim 13
Dependent Claim
31 words
The container for a sterile fluid material as defined in claim 10 wherein said fluid material is a sterile powder and said cylindrical container is formed with a finger pressible sidewall.
