Blood collection, storage and administering bag

Claim 2

A plastic bag for storing viable fluid comprising a pair of generally flat, flexible, face-to-face, opposed and peripherally joined side walls defining: a. a relatively large upper storage compartment; b. a relatively large lower storage compartment spaced a predetermined distance from said upper storage compartment; c. a means for selectively defining an intermediate third compartment comprising a relatively narrow transfer conduit neck formed by a pair of rupturable seals, one at the bottom of said upper compartment and another at the top of said lower compartment, said intermediate third compartment providing fluid flow communication between the two compartments while potentially defining a third storage compartment; d. said upper compartment tapering downwardly toward said neck to provide a progressively narrowing upper compartment approaching said conduit neck; and, e. said side walls being normally in a collapsed condition and being deformable outwardly by receipt of the viable fluid.

Claim 3

A container as defined in claim 1 further characterized in that said upper compartment is of a size to contain approximately 60% of a predetermined amount and wherein said lower storage compartment and said transfer conduit neck is detailed in size to contain approximately 40% of said predetermined amount.

Claim 4

A container as defined in claim 1 further characterized in that each of said storage compartments includes fluid entrance and fluid discharge means at the ends of said container. 4. A container as defined in claim 5 further characterized in that said predetermined capacity of said third compartment is approximately 50 cc.

Claim 5

A bag for the storage and gravity separation of viable fluids comprising a pair of opposed complimentary elastomeric sheets respectively provided with flat border flanges, each of said flanges confining within its border a relatively wide upper wall, a relatively wide lower wall and a relatively narrow intermediate wall joining the upper wall and lower wall at their central portions, said flanges being joined in contiguous abutting relationship; the flanges, adjacent said upper walls of said sheets, forming an upper, essentially straight, laterally extending, flange portion and a pair of opposed downwardly extending upper side flange portions, said upper side flange portions converging downwardly; said flanges, adjacent said intermediate walls, having a pair of intermediate flange portions in spaced relationship to each other and joined to said downwardly converging portions; said flanges, adjacent said lower walls, forming a pair of opposed downwardly diverging lower side flange portions and an essentially straight, lower flange portion joining the lower ends of said lower side flange portions, said upper walls defining a relatively large upper compartment tapering downwardly toward said intermediate walls, said lower walls defining a relatively large lower compartment tapering upwardly toward said intermediate walls, said intermediate walls defining a relatively small intermediate compartment providing communication between the upper and the lower compartments, said upper flanges being provided with hole means which permit the container to be supported, said flanges being provided with port means through which said viable fluid can be introduced into the compartments and removed therefrom, said intermediate walls being collapsible and having transverse spaced portions selectively sealable to each other and severable so that the upper and lower portions of said bag can be separated from each other and from said small intermediate compartment.

Claim 6

A bag for the storage and gravity separation of viable fluids comprising a pair of opposed complimentary elastomeric sheets respectively provided with flat border flanges, each of said flanges confining within its border a relatively wide upper wall, a relatively wide lower wall and a relatively narrow intermediate wall joining the upper wall and lower wall at their central portions, said flanges being joined in contiguous abutting relationship; the flanges, adjacent said upper walls of said sheets, forming an upper, essentially straight, laterally extending, flange portion and a pair of opposed downwardly extending upper side flange portions, said upper side flange portions converging downwardly; said flanges, adjacent said intermediate walls, having a pair of intermediate flange portions in spaced relationship to each other and joined to said downwardly converging portions; said flanges, adjacent said lower walls, forming a pair of opposed downwardly diverging lower side flange portions and an essentially straight, lower flange portion joining the lower ends of said lower side flange portions, said upper walls defining a relatively large upper compartment tapering downwardly toward said intermediate walls, said lower walls defining a relatively large lower compartment tapering upwardly toward said intermediate walls, said intermediate walls defining a relatively small intermediate compartment providing communication between the upper and the lower compartments, said upper flanges being provided with hole means which permit the container to be supported, said flanges being provided with port means through which said viable fluid can be introduced into the compartments and removed therefrom, said intermediate walls being collapsible and having transverse spaced portions selectively sealable to each other and severable so that the upper and lower portions of said bag can be separated from each other and from said small intermediate compartment.
