  • Patent number: 10920259
    Abstract: An improved disposable electrochemical test sensor designed to facilitate reducing volume of fluid samples. It has a short fluid chamber having two electrodes that functions as three electrodes (one working electrode, one reference electrode and one blank electrode). The chamber provides a reservoir from which a sample fluid can be quickly drawn into the chamber through capillary action. The novel potential reverse and curve-fitting technology of the test sensor provided by the present invention can effectively eliminate most common interferents existing in the fluid samples.

  • Patent number: 10571425
    Abstract: A disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance, but no additional air escape vent. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber through capillary action. The sampling entrance provided can draw fluid into the chamber through any part of the opening, allowing easy targeting the samples with small volume, picking up smeared samples, and added tolerance to users who jam the tip of the sensor into users' finger. The sampling entrance also serves as air escape vent. Such one opening sensor alleviates over-flow issue often encountered in convenient sensors.

  • Patent number: 10527576
    Abstract: A disposable electrochemical test sensor designed to facilitate sampling of fluid samples. It has a fluid chamber having a novel extra wide sampling entrance, but no additional air escape vent. The chamber provides a reservoir from which a sample fluid can be drawn into the chamber 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.

  • Patent number: 9939401
    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.

  • Patent number: 9897566
    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.
