    摘要: 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.

    摘要: An apparatus and method are provided for separating components of a fluid or particles. A separation vessel having a barrier dam is provided to initially separate an intermediate density components of a fluid, and a fluid chamber is provided to further separate these intermediate density components by forming an elutriative field or saturated fluidized particle bed. The separation vessel includes a shield for limiting flow into the fluid chamber of relatively high density substances, such as red blood cells. The separation vessel also includes a trap dam with a smooth, gradually sloped downstream section for reducing mixing of substances. Structure is also provided for adding additional plasma to platelets and plasma flowing from the fluid chamber. The system reduces clumping of platelets by limiting contact between the platelets and walls of the separation vessel.

    摘要: Methods and apparatuses are provided for inactivation of microorganisms in fluids or on surfaces. Preferably the fluids contain blood or blood products and comprise biologically active proteins. Preferred methods include the steps of adding an effective, non-toxic amount of an endogenous photosensitizer to a fluid and exposing the fluid to photoradiation sufficient to activate the endogenous photosensitizer whereby microorganisms are inactivated. Other fluids, including juices, water and the like, may also be decontaminated by these methods as may surfaces of foods, animal carcasses, wounds, food preparation surfaces and bathing and washing vessel surfaces. Alloxazines and K- and L-vitamins are among the preferred photosensitizers. Systems and apparatuses for flow-through and batch processes are also provided for decontamination of such fluids using photosensitizers.

    摘要: A centrifuge separation device is disclosed and includes a rotor configured to be connected to a centrifuge motor for rotation about an axis of rotation. A retainer is associated with the rotor and defines a passageway for a separation channel. A protrusion formed in one of the passageway walls extends towards and is spaced from the other of the passageway walls. The protrusion is sized to substantially block passage of materials in a predetermined density range and to substantially permit passage of materials outside of the predetermined density range. An indentation formed adjacent the protrusion in a wall of the passageway opposite the protrusion is configured to trap fluid during rotation of the rotor and to cooperate with the trapped fluid to maintain a substantially Coriolis-free pathway in a region of the passageway adjacent the protrusion.

    摘要: A centrifuge apparatus is used for collecting white blood cells (WBC), primarily mononuclear cells, from whole blood stratified into layers. A thin mononuclear (MNC) layer is formed at the interface of red blood cells and plasma. A barrier is positioned in the separation vessel of the centrifuge at a location to intercept the thin layer. MNC fluid is allowed to pool behind the barrier before collection is started. To collect the MNC pool, the stratified red blood cell layer is raised from below the interface level by slowing or reversing flow in the RBC exit line thereby causing the MNC pool to spill over the barrier into a well in which a collect line is positioned. Collection ceases when a desired percentage of the pool is removed and the normal position of the interface is re-established; thereafter the pool builds again. By raising the MNC pool from below, improvements in purity and collect volume are achieved. The collection procedure can be useful for harvesting granulocytes and, in general, any sparse stratified component of a centrifuged solution where the sparse component is layered between more dense and less dense strata.

A thin mononuclear (MNC) layer is formed at the interface of red blood cells and plasma. A barrier is positioned in the separation vessel of the centrifuge at a location to intercept the thin layer. An MNC collect port is positioned in front of the barrier to collect the thin layer. MNC fluid is allowed to pool behind the barrier to surround the collect port before collection is started. Collection ceases when the pool is removed and allowed to build again. By operating the collect in an intermittent fashion, improvements in purity and collect volume are achieved. The intermittent collection procedure can be useful for harvesting granulocytes and, in general, any sparse stratified component of a centrifuged solution where the sparse component is layered between more dense and less dense strata.
