    • The present invention related to a pregnancy test device that can selectively detect hyperglycosylated human chorionic gonadotropin (hCG-H) in a liquid sample. The sample can be deposited on a proximal portion of the device for transport to a distal portion of the device. The device can include a release medium formed of a first material and including a detectable label thereon and a capture medium, including a capture site, in fluid communication with the release medium and formed of a second, different material. At least one of the release medium and the capture medium includes a binding member that exhibits a moderate to high affinity for hCG-H and is selectively or preferentially reactive with hCG-H.
    • 本发明涉及能够选择性地检测液体样品中高糖基化的人绒毛膜促性腺激素(hCG-H)的妊娠试验装置。 样品可以沉积在器件的近端部分上,以便传输到器件的远端部分。 该装置可以包括由第一材料形成并且在其上包括可检测标签的释放介质以及与释放介质流体连通并由第二不同材料形成的包括捕获位点的捕获介质。 释放介质和捕获介质中的至少一种包括对hCG-H表现出中等至高亲和力并且与hCG-H有选择性或优先反应性的结合成员。

    • The present invention provides a time indicator and method of use for determining and visually displaying the passage of a predetermined period of time. The time indicator of the present invention comprises a top portion and a bottom portion. The top portion is a multi-layer segment comprising a dye support layer coated with a masking layer, which containing a viewing window therethrough, and a non-curing ink or dye permeable polymer layer containing a migrating agent. The bottom portion is a multi-layer segment comprising a base support layer and a migrating ink or dye printed on the top surface of the base segment. The time indicator apparatus further comprises a removable impervious film or middle layer, which can be removed allowing the top and bottom portions to come into contact with one another, thereby activating the time indicator. The time indicator of the present invention allows one to follow the uniform directional visual dye migration through the viewing window.
    • 本发明提供了一种用于确定和可视地显示预定时间段的通过的时间指示器和方法。 本发明的时间指示器包括顶部和底部。 顶部是包含涂覆有掩蔽层的染料支持层的多层段,其包含通过其观察窗口,以及含有迁移剂的非固化油墨或染料可渗透聚合物层。 底部是多层段,其包括基底支撑层和印刷在基部的顶表面上的迁移性墨或染料。 所述时间指示装置还包括可去除的不透水膜或中间层,其可被移除,允许顶部和底部彼此接触,从而启动时间指示器。 本发明的时间指示器允许通过观察窗口遵循均匀的定向视觉染料迁移。

    • The invention is an electronically processed single-step test device for detecting the presence of a preselected analyte in a fluid. The device includes a hollow rectangular outer casing, disposed within co joined upper and lower sections of the casing are assay material, an electronic processing system, and a LCD display. The LCD display is observable through a viewing window. The assay material is a sorptive material including a fluid sample application region in the form of a sample wick in fluid communication with a test strip. The test strip includes an analyte capture region adjacent to a light shield. The electronic processing system includes red and green LEDs which are alternately pulsed or energized over predetermined periods of time to determine if fluid test results show a marker or markers in the capture region indicative of the presence of a preselected analyte in the fluid. If so, Yes+ is displayed on the LCD. If not, No- is displayed on the LCD.
    • 本发明是用于检测流体中预选分析物的存在的电子处理单步测试装置。 该装置包括设置在壳体的共同连接的上部和下部中的中空矩形外壳,是测定材料,电子处理系统和LCD显示器。 LCD显示屏可通过观察窗观察。 测定材料是吸附材料,其包括与测试条流体连通的样品芯形式的流体样品施加区域。 测试条包括与光屏蔽相邻的分析物捕获区域。 电子处理系统包括在预定时间段内交替脉冲或通电的红色和绿色LED,以确定流体测试结果是否显示捕获区域中的标记或指示流体中预选分析物存在的标记。 如果是,则LCD显示Yes +。 如果没有,则显示屏上不显示“No”。
