Abstract: Metallic containers with high toughness characteristics are utilized to cryopreserve blood products and more particularly neonatal stem and progenitor cells at cryogenic temperatures. Metallic containers with high toughness and strength characteristics are durable at low temperatures and are capable to endure high stresses and impacts at ?196° C. These containers are better fit to preserve blood products without compromising their sterility or their medical integrity. Methods for fabricating metallic containers are also disclosed.

Abstract: A rotor having variable volumes adapted for collecting and centrifuging biological fluids. The rotor includes an impermeable flexible body having a cylindrical shape with stretchable vertical walls and semi pliant base. The rotor includes a rigid circular member that is seamlessly joined to the top of the flexible body. The rigid cover defines an opening having a rotary seal that maintains a closed system inside a spinning rotor. The rotary seal permits a plurality of non-rotating conduits to pass through for controlling the flow in and out of the rotor while it is spinning. In a preferred embodiment, the rotor includes a Core to stabilize the rotating fluids inside the separation chamber, and/or includes a diverter to divert the fluid entering the rotor to the periphery of the separation chamber for better processing. When the rotor is inserted in the centrifuge, the rigid cover is fixed at the top of the centrifuge bucket.

Abstract: This invention is based on combining dual heating means to warm the infused blood or other fluids to a normal body temperature and to compensate for any heat loss from the intravenous line. The infusate is directly heated to a normothermic temperature inside the apparatus as it flows in a plastic pouch having a winding shape passage. A particular object of the present invention is to provide a new and improved intravenous line heat exchanger to further warm the infusate at high flow rates, or to compensate for any heat loss to the environment at low or stagnant flow rates. The present invention provides a closed circuit heating fluid for the intravenous heat exchanger. The heated fluid used to warm the infusate in the intravenous line is maintained in a clean and isolated circuit. Either dray or wet fluids are used to warm the infusate in the intravenous line heat exchanger. The wet warming fluid is supplied in a disposable pouch fitted inside a warming chamber and integrated with the intravenous line.

Abstract: A whole blood collection system includes an automated pump/control unit and an accompanying disposable blood set. When combined and connected to a source of anticoagulant, these elements allow automatic priming of the blood set with anticoagulant and automatic collection of anticoagulated blood product according to three different collection modes. The unit's pump and the blood set are specially designed to cooperate during the collection process to assure that the collected product has a precise blood to anticoagulant ratio. During the collection procedure, the pump/control unit automatically collects data relating to the procedure. Additional data specifically identifying components of the blood set, such as the blood collection bag, along with identification data on the donor's registration form may be scanned into the pump/controller unit by a scanner associated with the unit; this facilitates positive sample identification and tracking.

Abstract: A centrifugal chuck comprising a chuck housing and a plurality of fingers pivotally mounted around the outer perimeter of the chuck housing. Each finger includes a tip, adapted to receive the base portion of a separation bowl. The fingers are mounted to the chuck housing so that the tips can pivot in a generally radial direction. Rotation of the chuck urges each gripping finger against the bowl.

Abstract: An improved centrifuge rotor formed of a bowl body and core for blood processing applications, such as cell washing or pheresis, is described. A tubular core adapted to rotate with the rotor defines a processing region between the core and the interior of the bowl body. A plurality of projections extend into the processing region to minimize formation of fluid Coriolis waves which would otherwise cause undesirable turbulence.

Abstract: A circuit breaker is shown having movable contacts carried by an operating member which moves between a circuit breaker contacts closed position and a circuit breaker contacts open position. An auxiliary switch has electrically conductive, flexible contact members adapted to engage an electrically conductive bridging shaft element carried by the operating member when the operating member is in one of its two positions to provide means for indicating the status of the circuit breaker.
