Patent ID: 7032910

Claim:
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.
