Integrated lancet and blood glucose meter system
First Claim
1. A blood glucose meter adapted to receive a disposable lancet and a plurality of sensors for effectively combining both lancing and measurement processes into a single device, comprising:
- a housing having an opening defined therein against which a user is to position a penetration location of the user'"'"'s skin;
a disposable lancet within the housing;
a lancet holder for mounting the lancet and driving the lancet through the opening to penetrate the skin of the user at the penetration location;
a plurality of sensors mounted within the housing and disposed along a feed track, each of the plurality of sensors including a substrate;
mechanical linkages within the meter for automatically indexing the sensors along the feed track; and
a power source and electrodes for providing electrical energy for performing an assay of body fluid drawn from the penetration location and applied to a sensor;
wherein the plurality of sensors includes at least a first test sensor and a second test sensor separate from but interlocked with said first test sensor; and
wherein said substrate of the first test sensor includes a pair of pins sized and shaped to interlock with a pair of recesses formed in the substrate of said second test sensor.

Abstract
A sensor array designed to be continuously indexed through a compatible blood glucose test monitor for the purpose of conducting multiple consecutive blood glucose measurements. The sensor array can be configured to substantially conform to a non-planar surface. In one embodiment, the sensor array includes first and second test sensors which are hingedly coupled together through a pin and socket interconnection. In another embodiment, the sensor array includes a unitary, non-conductive substrate which is scored to define one or more fold lines, a first set electrodes deposited on the substrate to define a first test sensor, and a second set of electrodes deposited on the substrate to define a second test sensor. In another embodiment, the sensor array includes a first test sensor, a second test sensor spaced apart from said first test sensor, a first spacer mounted on the first test sensor, a second spacer mounted on the second test sensor, and a unitary flexible member disposed across said first and second spacers.
