Abstract:
An improved disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The novel extra wide sampling entrance of the test sensor provided by the present invention can draw blood into the chamber not only from the front of the sampling entrance as usual in convenient sensors, but also from the top, bottom, left corner and right corner of the sampling entrance. 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 19):
An electrochemical test sensor comprising:\n a base layer having a sampling end and an electric contact end; a middle layer 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 disposed above the base layer, the middle layer forming a cutout region; an upper layer having a sampling end and an electric contact end, the upper layer being disposed above the middle layer; a fluid chamber defined by the recessed edge of the middle layer defining the cutout region; wherein the sampling end of the middle layer is recessed from a front edge of the upper layer sampling end and recessed from 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; wherein the sampling end of the upper layer is recessed from the sampling end of the base layer; and the fluid chamber having a sampling entrance defined by an open front opposite to the recessed edge of the middle layer, and by 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 front edge.
