Patent ID: 7829019

Claim:
A casing for use as a test kit using crushable ampoules prefilled with chemical or biological reagents, said casing, which is a molded casing comprising a distinct reaction chamber; an inspection arrangement constituting at least a portion of a wall of the reaction chamber configured for allowing a user to observe through the casing a color of a reaction inside the reaction chamber; at least two distinct cells each adapted to receive a crushable ampoule and having a flexible pressing area on an outer wall thereof for allowing said ampoule to be pressed and crushed; at least two channels, each of which connects one of the cells with said reaction chamber for allowing the passage of reagents from the cell to the reaction chamber, wherein each of said channels is built narrower than the respective cell and said reaction chamber thereby preventing shards of crushed ampoules from passing from the cell to the reaction chamber, and an inlet leading from an outside of the casing into an inner space of the reaction chamber, wherein the casing is equipped with a sampling probe having a bottom end configured to collect a sample of substance to be tested, to introduce the sample into the reaction chamber through the inlet, and to hold the sample inside the reaction chamber, wherein the probe and the casing are configured such that, when the probe is fully inserted into the casing, the collected sample is held in a predetermined point in front of the inspection arrangement thereby predetermining a location in front of the inspection arrangement for a color change to occur, and said two distinct cells having the ampoules are arranged directly above the reaction chamber so that the chemical or the biological reagents released from the crushed ampoules flow by gravity downward into said reaction chamber via said channels.
