Abstract
Abstract A container mixing system wherein a medicament is placed in a container mounted externally of a container with a diluent. Mixing of the medicament in one container with the diluent in the other is accomplished by moving a piston member with a piercing element in the direction of the diluent container to pierce a diaphragm or stopper in the medicament container. In one embodiment, the medicament container is sealed by means of a flange to the diluent container wall and the piercing element will pierce a diaphragm and the container wall with the piercing member also serving as an injection site.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
162 words
A container mixing system for intermixing components in a flexible intravenous solution container comprising: a first flexible thermoplastic container including wall means with a sterile fluid therein and including at least one administration port; a second container for sterile fluid material having a pierceable diaphragm at one end and including a tubular sealing member, said second container secured to said first container wall means and including a resilient piston member within and in slidable contact with said tubular sealing member to vary the volume of said second container in response to external force, said resilient piston member including a piercing portion; so that a force directed on said resilient piston member in the direction of said first container will effect both a piercing of said pierceable diaphragm and said first container wall means by said piercing portion and the removal of said second fluid material from said second container into said first container to provide fluid mixing with said first fluid material.
Claim 2
Dependent Claim
162 words
A container mixing system for intermixing components in a flexible intravenous solution container comprising: a first flexible thermoplastic container including wall means with a sterile fluid therein and including at least one administration port; a second container for sterile fluid material having a pierceable diaphragm at one end and including a tubular sealing member, said second container secured to said first container wall means and including a resilient piston member within and in slidable contact with said tubular sealing member to vary the volume of said second container in response to external force, said resilient piston member including a piercing portion; so that a force directed on said resilient piston member in the direction of said first container will effect both a piercing of said pierceable diaphragm and said first container wall means by said piercing portion and the removal of said second fluid material from said second container into said first container to provide fluid mixing with said first fluid material.
Claim 3
Dependent Claim
21 words
The container mixing system as defined in claim 1 wherein said fluid material in said second container is a powdered material.
Claim 4
Dependent Claim
170 words
A container mixing system for intermixing components in a flexible intravenous solution container comprising: a first flexible thermoplastic container including wall means defining a cavity for a sterile fluid therein and including at least one administration port; a second container for a sterile fluid material secured through said first container wall means in the manner of an additive port and having a pierceable stopper secured to one end thereof and placed within the said flexible container cavity, said second container including a tubular sealing member; a resilient piston positioned within and in slidable contact with said tubular sealing member which varies the volume of said container in response to external force, said resilient piston including a piercing pin member; so that a force directed on said resilient piston and in the direction of said first container will effect both a piercing of said pierceable stopper and the removal of said second fluid material from said second container into said first container to provide fluid mixing with said first fluid material.
Claim 5
Dependent Claim
170 words
A container mixing system for intermixing components in a flexible intravenous solution container comprising: a first flexible thermoplastic container including wall means defining a cavity for a sterile fluid therein and including at least one administration port; a second container for a sterile fluid material secured through said first container wall means in the manner of an additive port and having a pierceable stopper secured to one end thereof and placed within the said flexible container cavity, said second container including a tubular sealing member; a resilient piston positioned within and in slidable contact with said tubular sealing member which varies the volume of said container in response to external force, said resilient piston including a piercing pin member; so that a force directed on said resilient piston and in the direction of said first container will effect both a piercing of said pierceable stopper and the removal of said second fluid material from said second container into said first container to provide fluid mixing with said first fluid material.
Claim 6
Dependent Claim
21 words
The container mixing system as defined in claim 3 wherein said fluid material in said second container is a powdered material.
