Handheld optical diagnostic device having image system array
First Claim
1. A self-contained, optical hand-held diagnostic device, the device comprising:
- a body having a pocket-sized form factor sized and shaped for engagement by a user'"'"'s hand;
a power supply disposed within said body;
a display disposed integrally with said body;
a holder configured for receiving reagent sample media therein, the sample media having a plurality of test areas disposed in spaced relation thereon, each of the test areas configured to react with a sample when disposed in contact with the sample and to change color according to an amount of a constituent or property in the sample;
the holder sized and shaped for forming an indexed fit with the sample media;
a micro-array of imagers disposed within said body;
each of said imagers being superposed with a respective one of the test areas when the sample media is indexed within said holder;
the imagers being configured to each capture an image of the test area respectively superposed therewith;
a processor coupled to said imagers;
said processor configured to analyze said images of said test areas;
said processor configured to derive a diagnosis value from said analysis, and to generate an output corresponding thereto; and
said display configured to receive and display said output;
wherein said device is a unitary, self-contained, pocket-sized diagnostic tool.

Abstract
A self-contained, optical hand-held diagnostic device is provided with a body having a pocket-sized form factor sized and shaped for engagement by a user'"'"'s hand. The body includes an integral power supply and an integral display. A channel receives reagent sample media in an indexed fit. The sample media has a plurality of spaced test areas which change color according to an amount of a constituent or property in the sample. Imagers are located within the body so that each of the imagers is superposed with one of the test areas when the sample media is indexed within the channel, to capture an image thereof. A processor is coupled with the imagers to analyze the captured images. The processor also derives a diagnosis value from the analysis, and generates an output corresponding thereto. The display is configured to receive and display the output.

28. A method for reading reagent sample media, the sample media having a plurality of test areas disposed in spaced relation thereon, each of the test areas configured to react with a sample when disposed in contact with the sample and to change color according to an amount of a constituent or property in the sample, the method comprising the steps of:
-
(a) receiving the sample media into a holder of a unitary, self-contained, optical hand-held diagnostic device having an integral power supply and display, the holder sized and shaped for forming an indexed fit with the sample media; (b) with a micro-array of imagers disposed within said body, in which each imager is disposed in fixed superposition with a respective one of the indexed test areas, capturing images of said test areas; (c) with an integral processor, analyzing said images of said test areas; (d) deriving said amount of said constituent or property in said sample from said analysis; (e) generating an output signal corresponding to said amount; and (f) transmitting said output signal to the integral display. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38)
