Abstract
An auto-calibration system for diagnostic test strips is described for presenting data individually carried on each test strip readable by a diagnostic meter. The carried data may include an embedded code relating to data particular to that individual strip. The data is presented so as to be read by a meter associated with the diagnostic test strip in order to avoid manually inputting the information.
Claims11
A method of making a test strip, said method comprising:
- providing a sample chamber;
- providing an electrically insulating base layer;
- and
- providing a conductive pattern formed on the base layer including a plurality of electrodes, a plurality of electrical strip contacts, conductive traces electrically connecting the electrodes to at least some of the electrical strip contacts, and a distinct distal conductive region provided distal to the electrical strip contacts;
- providing an electrically insulating material including a pattern of apertures;
- and
- disposing the electrically insulating material over at least a portion of the distal conductive region such that the apertures expose a pattern of the underlying distal conductive region to at least partially form a distinct machine-readable code representative of data particular to the test strip.
A method of making a plurality of test strips, said method comprising:
- forming a plurality of test strip structures on one sheet, each of said test strip structures including:
- a sample chamber;
- an electrically insulating base layer;
- and
- a conductive pattern formed on said sheet including a plurality of electrodes, a plurality of electrical strip contacts, conductive traces electrically connecting the electrodes to at least some of the electrical strip contacts, and a distinct distal conductive region provided distal to the electrical strip contacts;
- providing an electrically insulating material including a pattern of apertures;
- disposing the electrically insulating material at least over a portion of the distal conductive region of each strip such that the apertures expose a pattern of the underlying distal conductive region on each strip to at least partially form a distinct machine-readable code representative of data particular to the test strip;
- and
- separating said test strip structures into said plurality of test strips.
