  • Publication number: 20100160137
    Abstract: A centrifuge for separating blood and blood components having a blood processing vessel mounted on a rotor of a centrifuge. A sensor in the outflow race of a return peristaltic pump detects air bubbles in the fluid within a return loop. The sensor may be a sonic sensor, a sonic pulse echo sensor, or capacitive plates. A pre-determined minimum bubble size or sizes or a cumulative volume may be selected, and the device operator may be warned only of the existence of bubbles that exceed a certain size or of a cumulative volume of bubbles, or the blood donation procedure may be stopped if a bubble exceeds a certain critical size or if a pre-determined volume of bubbles over a certain period or volume of fluid is exceeded.

  • Patent number: 7556611
    Abstract: An extracorporeal blood processing system having a centrifugal rotor, a control system, a plurality of peristaltic pumps, and a removable tubing circuit wherein blood components can be processed. A pump-balancing process, implemented by the control system, causes selected pumps to fill and empty a reservoir in the tubing circuit. Ratios of displaced volume per pump revolution or other pumping action can be used by the control system to increase the effectiveness and efficiency of the donation process. The pump-balancing process may be performed during priming or set-up of the blood processing system or during an actual donation.

  • Publication number: 20060122048
    Abstract: A centrifugal fluid separation system is disclosed for centrifugally separating a composite fluid into components thereof. This centrifugal separation system includes at least a centrifugal rotor which has a composite fluid containment area, a fluid flow channel/tubing and at least one separated component collection area defined therein. A composite fluid to be separated is delivered to the fluid containment area where under centrifugal forces the composite fluid is separated into components and then from which a component travels through an outlet channel to a respective separated component fluids flowing therethrough. A centrally disposed pump is also provided to move the separated component(s) to the collection area(s). Optical sensing of the interface of the separated fluid components may be used with a clamp to stop flow. A disposable bag and tubing system is also disclosed for use with reusable rotor devices.
