OPTICAL IMAGER AND METHOD FOR CORRELATING A MEDICATION PACKAGE WITH A PATIENT

摘要

A system is provided to correlate a medication package with a prescribed medication for a patient. The medication package accommodates an intended patient medication. The system includes an optical imager adapted to read an encoded symbol character comprising encoded patient information and further adapted to image an attribute of the medication package. The optical imager comprises a two-dimensional image sensor array and an imaging lens for focusing an image on the two-dimensional image sensor array. The two-dimensional image sensor array has a plurality of pixels formed in a plurality of rows and columns of pixels. The optical imager further includes a digital link to transmit a segment of data. The segment of data includes the patient information encoded in the encoded symbol character and the attribute of the medication package.

1. A system, comprising:
an imager comprising:
an image sensor for capturing images of (i) a symbol comprising encoded patient information and (ii) an attribute of a medication package, the image sensor comprising a plurality of pixels formed in a plurality of rows and columns of pixels;a lens for focusing images on the image sensor; anda digital link for transmitting data comprising patient information and an attribute of a medication package; a computer connected to the digital link for receiving the data from the imager's digital link; and a database coupled to the computer for correlating the data to a patient record and a medication package attribute library; wherein the attribute comprises a pattern of symbols and/or a grid pattern; wherein the attribute has a predetermined size characteristic; and wherein the system processes a captured image using the predetermined size characteristic to determine a size of a medication.
