Containers for reading and handling diagnostic reagents and methods for using the same
First Claim
1. A sensor system for determining a glucose concentration of a fluid sample, the sensor system comprising:
- an optical reagent-sensing device; and
a container including first and second rotatable storage devices having a continuous tape extending from the first rotatable storage device, past the optical reagent-sensing device, to the second rotatable storage device such that the first rotatable storage device holds and dispenses unused portions of the continuous tape and the second rotatable storage device holds and receives used portions of the continuous tape, the container further including a desiccant and a white-reflectance calibration standard, the calibration standard operative to calibrate the optical reagent-sensing device, the continuous tape including a diagnostic reagent and a polymer material,wherein the optical reagent-sensing device is operative to read the diagnostic reagent such that a glucose concentration for a fluid sample is determined in approximately 5 to 15 seconds.

Abstract
A container with a rotatable lid for reading and handling diagnostic reagents in tape form comprising a body portion, a lid portion, a continuous tape, a reagent-sensing device, and a storage device. The body portion includes an inner and outer surface. The lid portion is attached to the body portion and is adapted to rotate from a closed position to an open position. The continuous tape includes a diagnostic reagent. The reagent-sensing device is attached to either the body portion or the lid portion and adapted to read the diagnostic reagent. The storage device is attached to the body portion that is adapted to hold and dispense an unused portion of the continuous tape. During the rotation of the lid portion, the continuous tape is advanced from the first storage device and is extended over the reagent-sensing device.
