A test strip with a sample receiving chamber having a novel flared portion that terminates in a sample receiving opening. The flared portion provides a reservoir from which sample fluid can be drawn into the capillary or sample receiving chamber. The wider opening provided by the present invention is easier to “target” with a sample fluid. In preferred embodiments, the hydrophilic reagent layer extends to the dosing end or side of the test strip and further promotes wicking of the sample into the sample receiving chamber and thus reduces dose hesitation. In other preferred embodiments, a tapered dosing end is provided on the test strip in combination with the flared portion, and this combination create a test strip that will draw sample fluid into the sample receiving chamber regardless of where along the dosing edge of the test strip the fluid sample makes contact.
一种带有样品接收室的试纸,其样品接收室有一个新颖的喇叭形部分,该部分的末端是一个样品接收口。喇叭形部分提供了一个储液器,可将样品流体吸入毛细管或样品接收室。本发明提供的较宽开口更容易 "瞄准 "样品流体。在优选的实施方案中,亲
水试剂层延伸到试纸的定量端或侧面,进一步促进样品吸入样品接收室,从而减少定量犹豫。在其他优选的实施方案中,试纸上的锥形定量端与喇叭形部分结合在一起,这种组合产生了一种试纸,无论流体样品沿试纸的定量边缘接触何处,都能将样品流体吸入样品接收腔。
