  • DRY TEST STRIP WITH CONTROLLED FLOW AND METHOD OF MANUFACTURING SAME
    Publication number: 20080112848
    Abstract: A dry test strip assembly includes: a carrier base having a test port and a well adapted for receiving a dry test strip element, and a cover having a sample opening. The cover can be snapped onto the base with the sample opening aligned over the test port and with a test strip element compressed between the base and cover. A maximum dry test strip compression stop controls the maximum compression on the dry test strip, and a minimum dry test strip compression stop controls the minimum compression on the dry test strip. A rib between two test ports prevents fluid flow in the dry test strip element from one side of the rib to another, thereby separating the test strip element into a plurality of separate fluid compartments. A manufacturing system efficiently assembles the dry test strip assembly without handling by humans.
