Point of care analytical processing system
First Claim
1. A point of care analytical testing system comprising:
- a point of care reader comprising;
a housing having an interior;
an incubator disposed in the housing interior and having a rotor configured for rotation, the incubator having a plurality of circumferentially disposed slots;
a drive mechanism for rotating the rotor about a center axis; and
at least one measurement device disposed within the housing, the at least one measurement device being movable along a defined scan path; and
a plurality of analytical test elements, each analytical test element being sized for fitting in a slot of the incubator and comprising;
a planar support; and
a cartridge sized for retaining the planar support, the cartridge comprising an upper cover portion and a lower cover portion that supports ends of the planar support and has an elongated axial cavity over which the planar support is supported, the upper cover portion including at least one port configured for applying a quantity of sample to the retained support and wherein the planar support retains at least one of a dry chemistry chip comprising a porous spreading layer disposed in stacked relation with at least one reagent layer or a lateral flow assay device, wherein the elongated axial cavity enables the at least one measurement device to measure the sample by movement along the defined scan path.

Abstract
A point of care testing system includes a reader having an incubator disposed within a reader housing, the incubator having a rotor supported for rotation and having a plurality of circumferentially disposed slots. A drive mechanism is configured to rotate the rotor about a center axis A plurality of analytical test elements are sized for fitting in the slots of the incubator either manually or on demand. Each analytical test element commonly includes a support within a cartridge. The support retains at least one of a dry chemistry chip comprising a porous spreading layer disposed in stacked relation with at least one reagent layer or a lateral flow assay device wherein the plurality of test elements can assume a common form factor with multiplexed capability, and in which cartridges are preferably gated to enable random access processing.
