Patent ID: 8716006

Claim:
A fluid processing system comprising: a drive assembly with a longitudinal axis of rotation, the drive assembly comprising a circular contact surface at a first end of the drive assembly, the circular contact surface comprising a heater at a first radial position and a magnet at a second radial position; a cartridge body disposed proximate the first end of the drive assembly and non-rotatably disposed on the circular contact surface, the cartridge body comprising an inner cylindrical surface, a syringe molding extending from an outer surface of the cartridge body, a syringe port in the syringe molding that connects the inner cylindrical surface to the outer surface, the inner cylindrical surface and the outer surface being opposite each other and parallel the longitudinal axis of rotation of the drive assembly; and a reservoir insert rotatably disposed to the inner cylindrical surface and operatively connected to the drive assembly such that rotation of the drive assembly causes the reservoir insert to rotate within the cartridge body, wherein the reservoir insert comprises a cylindrical sidewall with a plurality of fluid ports disposed on an outside surface thereof including reservoir fluid ports, a first through-channel fluid port and a second through-channel fluid port, each fluid port being a first distance from a bottom of the reservoir insert such that each fluid port may be selectively aligned with the syringe port, the cylindrical sidewall further comprising a plurality of relief ports disposed on the outside surface and above the plurality of fluid ports, a plurality of reservoirs within a perimeter defined by the cylindrical sidewall, each one of the plurality of reservoirs being fluidly connected to one reservoir fluid port of the plurality of fluid ports and one relief port of the plurality of relief ports, and a through channel extending along the bottom of the reservoir insert, the through channel being fluidly connected to the first through-channel fluid port and the second through-channel fluid port at respective ends of the through channel, the through channel being selectively positionable proximate the heater or the magnet by rotation of the reservoir insert such that contents of the through channel can experience heat from the heater or a magnetic field from the magnet.
