Claim Text:
1. A medical system comprising: at least one handheld medical device configured to perform at least one medical function; and at least one medical consumable item having at least one two-dimensional optical code provided thereon, wherein the medical device is configured to interact with the medical consumable item to perform the medical function, the medical device comprising: at least one code reader configured to read at least one information component from the optical code of the medical consumable item when the medical consumable item is in a read position relative to the medical device, the code reader comprising: at least one image sensor having a plurality of sensors, at least one planar light-optical fiber plate having first and second planes, the plate being generally configured to transport light from the first plane to the second plane, the plate further being generally configured to guide an image of the optical code to the image sensor without appreciably altering the image during transport, the optical code comprising a plurality of optically readable modules each comprising a smallest information unit, wherein the light-optical fiber plate comprises a plurality of substantially parallel oriented optical fibers arranged perpendicular to the first plane and the second plane, and at least one illumination device configured to illuminate the optical code on a side of the optical code generally facing the image sensor, wherein the medical consumable item and the medical device being positioned relative to each other in the read position such that a first distance between the plate at the first plane and the optical code is less than a second distance between the midpoints of adjacent modules of the optical code, wherein the illumination device comprises at least one light source and is configured to illuminate the optical code on one side, from the same side on which the image sensor also is provided, in one or more of the manners of (a) through the plate, (b) from a side of the optical code substantially perpendicular to a viewing direction of the plate through a carrier material of the medical consumable item, and (c) through the image sensor onto the medical consumable item in a region of the optical code, and wherein the medical function is performed on a patient sample or influences a patient body state.
