  • Patent number: 8465696
    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.

  • Patent number: 7494818
    Abstract: A multilayer test strip that measures concentrations of multiple analytes from a single whole blood sample. The test strip includes a test matrix of several layers held together in constant contact by a test strip holder. The invention is characterized in that it has no moving parts, which is made possible by the novel use of an elongate disbursement layer that spreads blood throughout its entire length, despite having layers with known wicking properties adjacent to and in contact with it. Since the invention relies primarily on a vertical flow format, the test strip is advantageously quite compact. With a single 30-50 microliter sample of blood applied thereto, the novel test strip can provide readings of total cholesterol, HDL cholesterol and triglycerides. From these, LDL can be calculated, thereby providing a full “lipid panel.” Other analytes such as glucose and ketones may be included in the test strip in addition to or in lieu of one or more of the other analytes.

Since the invention relies primarily on a vertical flow format, the test strip is advantageously quite compact. With a single 35 microliter sample of blood applied thereto, the novel test strip can provide readings of total cholesterol, HDL cholesterol and triglycerides. From these, LDL can be calculated, thereby providing a full “lipid panel.” Other analytes such as glucose and ketones may be included in the test strip in addition to or in lieu of one or more of the other analytes.

  • Publication number: 20070090010
    Abstract: The present invention is direct to a filled package comprising a transparent or translucent container exhibiting the tint of a first color and being adapted to house a liquid; and a liquid exhibiting the tint of a second color which is different than the first color and being housed in said container, the tint of the first color of the container and the tint of the second color of said liquid cooperating such that the tinted container when filled with the tinted liquid exhibits an appearance having the tint of a third color.

  • Publication number: 20040011379
    Abstract: In a chamber (11), a SiOF film is formed on a wafer W using a plasma CVD method. A film remaining inside the chamber (11) is cleaned up using a gas containing NF3. A manometer (28) is prepared for the chamber (11). An end point of cleaning of the chamber (11) is detected by moni-toring the pressure inside the chamber (11).
