Embodiment Construction

[0039] In the following description, a specific embodiment for carrying out the present invention will be described with reference to the accompanying drawings. It should be understood that other embodiments are possible with certain structural changes without departing from the scope of the present invention.

[0040] One aspect of the invention includes a chromatographic assay device particularly suited for the assay of biological samples. These devices are suitable for the direct addition of biological samples without pre-extraction steps, and the structure of such devices reduces the number of handling steps on the sample, thus simplifying the assay work.

[0041] figure 1 Shown is the die-cut condition of the integral housing 10 of the present invention. The overall housing is preferably die cut from SBS paperboard having a thickness of 0.024 inches. It should be understood, however, that other materials may be used to manufacture the housing of the present invention. ...

Abstract

A chromatographic assay test device for use with immunoassays. The test device has a sample collection member pivotally coupled to a test strip receiving member. The sample collection member has a window for applying a test sample to a pad accessible through the window and the pad is repositionable to an inverted position to contact a chromatographic member inserted into the test device. The chromatographic member is then brought into opposition to the sample collection member thus improving test performance by reducing the manipulation of samples. The test device is constructed from five interconnected panels which are die cut from SBS cardboard. The first panel (12) has a window (14) for inserting a test strip and the second panel (20) has a window (22) for viewing the test strip during the test procedure. The third panel (30) has the repositionable pad section. The fourth panel (40) has a window (42) for applying the test sample and the fifth panel (50) covers the test sample window (42). The first and second panels are coupled to form a first planar member and the third and fourth panels are coupled to form the sample collection member. The fifth panel includes a reusable adhesive for securing the fifth panel over the sample window in the fourth panel.

Description

technical field [0001] The present invention generally relates to an assay method and equipment based on immunochemistry, and more specifically, relates to an integral housing, sample collection technology and equipment with sample lifting and rotating tabs. Background technique [0002] Chromatographic assays are one of many analytical methods used to detect and / or characterize analytes, especially biological analytes. Chromatographic systems of this type are often used by physicians and medical personnel for in-office rapid diagnosis and treatment monitoring of a variety of conditions and conditions. Patients are also increasingly using these methods for home self-monitoring of such conditions and conditions. One of the most important methods of this type is the "thin layer" method, in which the solvent penetrates through a thin layer of flat absorbent medium. [0003] Although these methods are effective, the currently commonly used chromatographic techniques using test...
