    摘要: A blood processing assembly (14) includes a separation element (12) for separating blood from a source into a first component and a second component. The assembly also includes a fluid path (18) that conveys blood between the source and the separation element. The fluid path includes one or more in-line cassettes (22A/B/C) that serve in association with peristaltic pumps to centralize pumping and valving functions of the system. The cassettes also serve to segregate the flow paths of the blood components from each other.

    摘要: A method for separating platelets from a platelet-rich suspension comprising rotating a separation zone about an axis (14) at a given angular velocity (Φ), the separation zone including a low-G side (16) located closer to the rotational axis (14) than the other, high-G (18) to create between them a chamber (10) having a radial thickness (h) and an axial height (Z) measured with respect to the axis (14) of rotation, and an inlet (20) for introducing a platelet-rich suspension and the separation zone establishing a relationship between the radial thickness (h) and the axial height (Z) of the chamber (10) that taking into account the given angular velocity of rotation (Φ) and the given kinematic viscosity (v) of the platelet-rich suspension introduced through the inlet (20), represents a value (μ) that is less than 700, where μ = (2h3)/(Z).

    摘要: An umbilicus (24) conveys fluid between a stationary body and a rotating body in a small, compact operating environment. The umbilicus comprises an elongated body (200) including a proximal end, a distal end, and a middle region between the proximal and distal ends. A first support block (204) is attached to the proximal end. A second support block (206) is attached to the distal end. The first support block (204) includes a strain relief sleeve (212). The umbilicus is otherwise free of any other strain relief sleeve. A thrust bearing member (214) in the middle region spaced apart from the strain relief sleeve (212) and the distal end. The umbilicus is otherwise free of any other thrust bearing member. The thrust bearing member (214) has an inner annular body (218), an outer annular body (216) about the inner annular body (218), and an array of ball bearings (220) between the inner and outer annular bodies. The ball bearings (220) support the inner annular body (218) for rotation relative to the outer annular body (216).

    摘要: Un système (234), conçu pour surveiller la zone d'interface entre les constituants cellulaires et le plasma dans une chambre de séparation (80) utilise un mécanisme détecteur (236) conçu pour dégager de l'énergie dans la zone d'interface; cette énergie étant absorbée par les constituants cellulaires. Le mécanisme détecteur (244) détecte également l'intensité de l'énergie qui n'est pas absorbée par la zone d'interface, de manière à générer un signal de sortie caractéristique de l'intensité non-absorbée. Le système (234) déplace la zone d'interface par rapport au mécanisme détecteur pendant un temps déterminé. Un premier circuit (268) mesure les variations du signal de sortie caractérisant l'intensité non-absorbée pendant le temps déterminé et génère une sortie fonction du temps. Un second circuit (270) peut dériver la dimension physique de la zone d'interface basée sur la sortie fonction du temps.
