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 14):
An electrochemical test sensor comprising:\n a base layer having a sampling end and an electric contact end, the base layer having electrodes at the sampling end, and electric contacts at the electric contact end, the electrodes being in communication with the electric contacts; 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 being disposed above the base layer, the middle layer forming a cutout region defined by at least a portion of a front edge being recessed from the middle layer sampling end along the width of the middle layer; an upper layer having a sampling end and an electric contact end, the upper layer being disposed above to the middle layer; a fluid chamber defined on a top by the upper layer, on a bottom by the base layer, on a side by the recessed edge of the middle layer defining the cutout region, and having a sampling entrance defined by an open front opposite to the recessed edge of the middle layer, the fluid chamber sized and configured to receive a fluid by capillary action, and sized and configured to expose the electrodes of the base layer to the fluid; and wherein the base layer further defines a recessed notch along its height on the sampling end, the recessed notch creating a bottom opening at a front bottom edge of the test sensor, the notch and bottom opening providing a fluid communication with the fluid chamber from a front edge and a bottom surface of the electrochemical test sensor, the recessed notch sized and configured to provide the fluid communication via capillary action, and positioned below an area defined by the fluid chamber so as to directly communicate with the fluid chamber, wherein the bottom opening is configured to allow a fluid to enter the fluid chamber against a force of gravity when the bottom surface of the electrochemical test sensor is parallel to a surface that the fluid is on.
