Abstract
A test sample card is provided with a locking feature for achieving a positive, locking engagement with a transfer tube that conducts fluid into the interior of the test sample card. The locking feature consists of a tubular channel inwardly disposed from the fluid intake port that has an inner annular rim defining a restriction. The annular rim is of a reduced diameter relative to the diameter of the transfer tube. A recessed region is positioned inwardly from the restriction that has an opening in one of the surfaces of the card body. When the transfer tube is inserted into the tubular channel, the first end is forced past the restriction into the recessed region, with the annular rim compressing the transfer tube. The user is able to sense with their hands when the first end is inserted past the restriction. Visual observation of the first end of the transfer tube through the opening in the card surface confirms that the transfer tube has been properly inserted into the test sample card.
