Abstract
Biomedical containers for sampling and mixing biological fluids are disclosed. The biomedical containers are at least substantially spherical and include access sites for accessing the container interior. The containers may be included as part of a disposable biological fluid processing kit.
Claims23
A biomedical container comprising a spherical profile, integrally molded flexible wall devoid of sealed-together multiple sheets comprising a polymeric material and defining a spherical interior, said polymeric material of said integral container wall being sufficiently flexible such that said container can be compressed to a non-spherical profile and has a shape memory that allows said container to return from said non-spherical profile to said spherical profile, said container wall comprising an integrally-formed inlet and a plurality of sealed and openable access sites, wherein said inlet comprises a flow path and includes a valve within said flow path, said valve being openable and closeable by an actuator located outside said flow path.
A disposable biological fluid processing kit comprising
- a venipuncture access device,
- a biological fluid collection container,
- a flow path between said venipuncture access device and said biological fluid collection container and
- a biomedical container comprising a spherical profile, integrally molded flexible outer wall devoid of sealed-together multiple sheets comprising a polymeric material and defining a spherical interior chamber devoid of dead zones for cellular material or fluid to become trapped, said integral outer wall being sufficiently flexible such that said spherical biomedical container can be compressed to a non-spherical profile and has a shape memory that allows said container to return from said non-spherical profile to said spherical profile, said integral wall comprising an integrally-formed inlet port and a plurality of sealed and openable access sites and wherein said container has a selected volume and a selected radius such that the surface area to volume ratio is less than 1.
