An adaptable blood processing platform comprises a blood processing device and a ground engaging frame including a shelf to which the blood processing device is secured. The frame supports the shelf for movement between a lowered position and a raised position. The shelf can be supported, e.g., for swinging cantilevered movement about an axis between the lowered and raised positions. The shelf can be supported, e.g. , by a scissors linkage assembly coupled to the shelf for lowering and lifting the shelf between a lowered and raised positions. In the lowered position, the center of gravity of the blood processing device is located a first distance above ground, which is conducive for stable storage and/or transport of the platform. In the raised position, the center of gravity of the blood processing device is located a second distance above ground greater than the first distance, which is conductive for set-up and operation of the platform.

We claim: 1. A blood processing platform comprising: a blood processing device having a center of gravity and a predetermined height, and a ground engaging frame including a shelf to which the blood processing device is secured in all shelf positions, the frame supporting the shelf for movement about an axis between a lowered position suitable for transporting the blood processing device on the shelf, in which the center of gravity of the blood processing device is located a first distance above ground, and a raised, cantilevered position, suitable for operating the blood processing device on the shelf in which the center of gravity of the blood processing device is located a second distance above ground greater than the first distance; said frame comprising a first and a second set of fore and aft risers, the distance between the fore riser of said first set and the aft riser of said first set at least equal to the height of said blood processing device; said fore and aft risers substantially vertically disposed when the shelf is in the raised and lowered positions; said frame further comprising a locking assembly that telescopes between a retracted condition and an extended condition, said locking assembly disposed between the frame and the shelf for supporting said shelf in the raised, cantilevered position when the locking assembly is in the extended condition and for permitting said shelf moved to said lowered position when said locking assembly is in the retracted condition. 2. A blood processing platform according to claim 1 wherein, in the lowered position, the shelf is supported in a generally non-horizontal orientation with respect to the ground, and wherein, in the raised, cantilevered position, the shelf is supported in a generally non-vertical orientation with respect to the ground. 3. A blood processing platform according to claim 1 wherein the frame includes at least one ground engaging wheel for transporting the frame. 4. A blood processing platform according to claim 3 wherein the frame includes at least one ground engaging leg spaced from the ground engaging wheel, the leg and wheel together supporting the frame in an upright position during movement of the shelf between its lowered position and its raised, cantilevered position. 5. A blood processing platform according to claim 4 wherein the frame includes a handle for maneuvering the frame during transport on the at least one ground engaging wheel. 6. A blood processing platform according to claim 1 wherein the shelf includes a removable cover for enclosing the blood processing device. 7. A blood processing platform according to claim 1 wherein the frame includes a mechanism for releasably locking the shelf when in the raised position. 8. A blood processing method comprising the steps of: mounting a blood processing device on a shelf such that the blood processing device is carried by a wheeled cart, the cart supporting the shelf for movement about an axis between a lowered position suitable for transporting the blood processing device on the shelf, in which the center of gravity of the blood processing device is located a first distance above ground, and a raised, cantilevered position, suitable for operating the blood processing device on the shelf in which the center of gravity of the blood processing device is located a second distance above ground greater than the first distance, with the blood processing device secured to the shelf in all shelf positions, said cart including a frame comprising a first and a second set of fore and aft risers, the distance between said first fore riser and said second fore riser at least equal to a width of said blood processing device, said fore and aft risers substantially vertically disposed when the shelf is in the raised and lowered positions, said frame further comprising a locking assembly that telescopes between a retracted condition and an extended condition, said locking assembly disposed between the frame and the shelf, supporting said shelf in the raised, cantilevered position with the locking assembly when said locking assembly is in the extended condition, permitting said shelf moved to the lowered position when said locking assembly is in the retracted condition, transporting the blood processing device on the cart while the shelf is in the lowered position, and operating the blood processing device on the cart while the shelf is in the raised, cantilevered position. 9. A blood processing method according to claim 8 wherein in the lowered position, the shelf is supported in a generally non-horizontal orientation with respect to the ground, and wherein in the raised, cantilevered position, the shelf is supported in a generally non-vertical orientation with respect to the ground. 10. A blood processing method according to claim 8 further including the step of enclosing the blood processing device with a cover on the shelf. 11. A blood processing platform comprising: a blood processing device having a center of gravity and a predetermined width, and a ground engaging frame including a shelf to which the blood processing device is secured in all shelf positions, the frame supporting the shelf for movement about an axis between a lowered position suitable for transporting the blood processing device on the shelf, in which the center of gravity of the blood processing device is located a first distance above ground, and a raised, cantilevered position, suitable for operating the blood processing device on the shelf in which the center of gravity of the blood processing device is located a second distance above ground greater than the first distance; said frame comprising a first and a second set of fore and aft risers, the distance between said first fore riser and said second fore riser at least equal to the width of said blood processing device; said fore and aft risers substantially vertically disposed when the shelf is in the raised or lowered positions; said frame further comprising a locking assembly that telescopes between a retracted condition and an extended condition, said locking assembly disposed between the frame and the shelf for supporting said shelf in the raised, cantilevered position when the locking assembly is in the extended condition and for permitting said shelf moved to the lowered position when the locking assembly is in the retracted condition. 12. A blood processing platform comprising: a blood processing device having a center of gravity and a predetermined width, and a ground engaging frame including a shelf to which the blood processing device is secured in all shelf positions, the frame supporting the shelf for movement about an axis between a lowered position for transporting the blood processing device on the shelf, in which the center of gravity of the blood processing device is located a first distance above ground, and a raised, cantilevered position, suitable for operating the blood processing device on the shelf in which the center of gravity of the blood processing device is located a second distance above ground greater than the first distance; said frame comprising a first and a second set of fore and aft risers; said fore and aft risers substantially vertically disposed when the shelf is in the raised or lowered positions; a locking assembly that telescopes between a retracted condition and an extended condition, said locking assembly disposed between said frame and said shelf for applying over center force to said shelf when said shelf is in said lowered position and when said locking assembly is in the retracted condition to resist free swing movement of said shelf, and said shelf supported by the locking assembly in a weight supporting condition when the shelf is in said raised position and when said locking assembly is in the extended condition.
