Abstract:
The present invention relates to disposable test sensors having improved sample application and measuring properties and their uses for detection, preferably, quantitative measurement, of analyte in a liquid sample like blood. In particular, the invention provides for an electrochemical biosensor which has a thin-layer fluid chamber having funnel-like shape with a novel extra wide opening as sampling entrance and a vent opening at the tip of the chamber for air escape. The thin-layer fluid chamber provides a reservoir from which a sample fluid can be drawn into it through capillary action. The extra wide sampling entrance provided by the present invention can draw blood into the chamber through any part of the opening, thus it allows easy targeting the samples with small volume, picking up smeared samples and it is more tolerant to users who jam the tip of the sensor into users' finger.

Claim (Index 1):
An electrochemical test sensor comprising:\n a base layer having a sampling end and an electric contact end; a middle layer formed of an electrically insulating material having a width approximately equal to a width of the base layer, and having a sampling end and an electric contact end, the middle layer forming a cutout region; an upper layer having a sampling end and an electric contact end; and a fluid chamber formed by the middle layer defining the cutout region, wherein the cutout region extends from the sampling end towards the electric contact end away from the sampling end; wherein the sampling end of the middle layer is slightly recessed from a front edge of the upper layer sampling end and a front edge of the base layer sampling end, wherein the upper layer, middle layer, and base layer define two side openings in communication with the fluid chamber, a first side opening being on a first side of the sensor at the sampling end, a second side opening being on a second opposite side of the sensor at the sampling end, the two side openings being defined by the middle layer sampling end being slightly recessed from the front edge of the upper layer and base layer sampling ends; the fluid chamber having a continuous sampling entrance defined by an open front opposite to the recessed edge of the middle layer and the two side openings; wherein a combined length of the open front and the two side openings of the fluid chamber is less than a perimeter length of the middle layer cutout region.
