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.

Two electrodes functioning as three electrodes in the fluid chamber of a test strip

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.

Disposable test sensor with improved sampling entrance

The present invention relates to the technical field of electrochemical detection, in particularly to a method for distinguishing between quality control liquid and real sample in an electrochemical test system with recognition device controller and recognition system. The method includes: (1) applying an AC voltage signal to the electrode surface(s) of an electrochemical test strip, (2) measuring the AC impedance angle (phase angle) value between working electrode and reference electrode after drawing a test sample into the fluid chamber of an electrochemical test strip, (3) automatically judging the test sample as quality control liquid or real sample according to the AC impedance angle value. The method provided by the invention can automatically distinguish between quality control liquid and real sample in an electrochemical test system, simplifying the operation steps of quality control, avoiding the misoperation under manual quality control mode, and improving the accuracy and reliability of measurement results.

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.

Test sensor with multiple sampling routes

The present invention relates to a test-strip storage vial, comprising a vial body, a test-strip storing chamber, a button pole, and a baffle; wherein the test strip storing chamber is disposed inside the vial body; wherein the button pole is provided at the side of the vial body and capable of moving vertically; wherein the baffle is provided at one end of the storing chamber and capable of moving horizontally, wherein a top-lifted unit is provided at another end of the storing chamber; wherein the top-lifted is capable of vertically supporting test strips disposed in the storing chamber and enables the test strips to move towards the baffle; wherein the button pole is connected to the baffle through a flexible part; wherein the baffle is connected to the vial body through an elastic part; wherein the test strip is ejected by the horizontal movement of the baffle.

The disclosure includes a control method for test strip electrodes. The method can include inserting a test strip into a glucose meter and applying a predetermined voltage to the working electrode W of the test strip. The Method can also include applying a sample to the test strip and acquiring real-time data of current generation at the electrodes Rand Rof the test strip. Some embodiments can also include determining whether the electrode Rgenerates current earlier than the electrode Ror not.

Control method and system for test strip electrodes

The present invention relates to a test-strip storage vial, comprising a vial body, a storing chamber for storing test strips, a push button, and a top-lifted unit; wherein the push button is located at one end of the storing chamber; wherein a top-lifted unit is located at another end of the storing chamber; wherein the push button slides horizontal to remove test strips the storing chamber; wherein the top-lifted unit supports the test strips and lifts the test strips in a vertical direction; wherein the vial body further comprising an upper cover and lower vial body, wherein the lower vial body is detachably connected to the upper cover; wherein the push button is glidingly connected with the upper cover, wherein the top-lifted unit is located in the lower vial body; wherein a push button spring provides horizontal tensile force is disposed between the upper cover and the push button.

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.
