    • An electrochemical biosensor test strip that has a minimum volume blood sample requirement of about 9 microliters. The test strip has working and counter electrodes that are substantially the same size and made of the same electrically conducting material placed on a first insulating substrate. Overlaying the electrodes is a second insulating substrate, which includes a cutout portion that forms a reagent well. The cutout portion exposes a smaller area of the counter electrode than the working electrode. A reagent for analysis of an analyte substantially covers the exposed areas of working and counter electrodes in the reagent well. Overlaying the reagent well and affixed to the second insulating substrate is a spreading mesh that is impregnated with a surfactant. The small cutout portion of 4 millimeters by 4.2 millimeters, small mesh of 6 millimeters by 5.8 millimeters, and small amount of reagent, 4 microliters before drying, allow the test strip to analyze a whole blood sample of about 9 microliters.
    • 电化学生物传感器测试条具有约9微升的最小体积血液样本要求。 测试条具有基本上相同尺寸并由放置在第一绝缘基板上的相同导电材料制成的工作对电极。 覆盖电极是第二绝缘基板,其包括形成试剂的切口部分。 切除部分暴露对电极的面积比工作电极的面积小。 用于分析分析物的试剂基本上覆盖试剂阱中的工作和对电极的暴露区域。 将试剂叠加并固定到第二绝缘基底上的是用表面活性剂浸渍的铺展网。 4毫米×4.2毫米的小切口部分,6毫米×5.8毫米的小网孔和少量试剂,干燥前4微升,允许测试条分析约9微升的全血样品。

    • A test strip with a sample chamber is secured to a meter. The sample chamber in the portion of the test strip that extends out of the meter is illuminated by transmitting light from a light source inside the meter internally through the test strip towards the sample chamber. By way of analogy, the test strip acts in a fashion similar to a fiber optic cable or optical wave guide by transmitting the light from the meter to the remotely located sample chamber that extends outside the meter. The user is then able to easily see the sample chamber of the test strip in dark conditions so that the user is able to readily align the sample chamber with the drop of fluid on the skin as well as view the sample chamber in order to ensure proper filling. The light also illuminates a test strip slot into which the test strip is inserted.
    • 带有样品室的测试条固定在仪表上。 通过将来自仪器内部的光源的光透过测试条朝向样品室传送来自测量仪器外延的测试条部分中的样品室。 通过类推,测试条以与光纤电缆或光波导相似的方式通过将来自仪表的光传输到延伸到仪表外部的位于远处的样品室。 使用者然后能够在黑暗的条件下容易地看到测试条的样品室,使得用户能够容易地将样品室与皮肤上的一滴液体对准,并且观察样品室以确保适当 填充。 灯也照亮测试条插入的测试条槽。
