    摘要: A centrifuge comprising a yoke element that rotates about a rotational axis and a processing chamber having an axis. The processing chamber includes a bowl element, a spool element, and a mechanism for joining the spool and bowl elements for relative movement between a mutually cooperating position for centrifugal processing and a mutually separated position for loading. A hinge attaches the processing chamber to the yoke element for pivotal movement between an operating position and an access position. In the operating position, the spool and bowl elements are in their mutually cooperating position and oriented for rotation with the yoke element about the rotational axis. In the access position, the processing chamber axis lies outside the axis of rotation and the spool and bowl elements are oriented for movement from their mutually cooperating position into their mutually separated position.

    摘要: A peristaltic pumping apparatus and associated method to control power to the pump rotor to establish, during a preestablished first time period, a selected first angular velocity and sequentially establishing during a preestablished second time period immediately following the first time period a second angular velocity different than the first angular velocity. In this fashion, the apparatus and method achieve flow rates well below the minimum continuous flow rate of the rotor.

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

    摘要: A cassette serves in association with one or more peristaltic pumps to centralize pumping, valving, and pressure sensing functions. The cassette includes a housing having first and second pump ports. A flexible tubing loop extends between the first and second pump ports outside the housing for engagement with an external peristaltic pump element. A liquid port on the housing attaches to a length of tubing that also extends outside the housing. Liquid passages within the housing that establish communication among the liquid port, the first pump port, and the second pump port. Valve stations formed within the housing are responsive to the application of external force for controlling liquid flow through the liquid passages. A sensing chamber is formed within the housing along at least one liquid passage. The sensing chamber transmits information regarding liquid pressure present within the one liquid passage to an external sensing element.

    摘要: A blood component collection system and method each utilizes centrifugation to first separate whole blood into red blood cells and platelet-rich plasma. Noncentrifugal separation is then utilized to further separate the platelet-rich plasma into platelet concentrate and plasma which is virtually free of platelets. The system and method are applicable for use in association with both batch and continuous flow procedures.
