摘要： A device for collecting and transporting aqueous fluid from the oral cavity to a lateral chromatographic strip for test is disclosed. The lateral chromatographic strip is placed within and extend along a cavity defined in a housing. At least one inspection site to the lateral chromatographic strip is provided to enable inspection of selected sites on the lateral chromatographic strip for test results. A porous wick material protrudes from the housing to a collection site exterior of the housing at one end and communicates to the lateral chromatographic strip at the other end. The porous wick material has particulate construction, the particles adsorbing aqueous oral fluid to transport the fluid from the mouth to the lateral chromatographic strip without substantial absorption. The particles of the porous wick material are bound together to define a continuous interstitial volume for the flow of oral fluid to be transported and are treated to be hydrophilic to the adsorbed oral fluids. The porous wick material readily releases oral fluid to the lateral chromatographic strip. Prevention of reverse flow to the oral cavity from the lateral chromatographic strip naturally occurs due to the circuitous flow path of the porous wick material. A bite plate is coupled to the housing and insertable between the teeth of the patient to position the porous wick in the oral cavity for collecting the oral fluid. The bite plate is typically held in place by the occlusal force of the teeth, preferably the molars and/or the bicuspids, to position the porous wick in the buccal space. By observing the lateral chromatographic strip while the test device is in the mouth immediate test results are obtained.

摘要： A method for rapid collection and assay of oral fluids is disclosed. The method comprising the steps of: (a) placing an assay device into an oral cavity, (b) removing said assay device from said oral cavity; and (c) determining the presence or absence of at least one analyte. The assay device used in the method comprises: (i) an assay portion housing an immunochrornatographic lateral flow assay strip, the lateral flow assay strip containing at least one reagent selected from an antigen and an antibody that is used to detect one of the presence or absence of at least one analyte in a fluid; (ii) a neck portion extending from the assay portion, the neck portion forming a channel for delivery of fluid to said assay strip and the channel being defined by a first, narrow part proximal to the assay portion and a second part including an opening for receiving the oral fluid, wherein the second part includes a channel width that is substantially wider than the channel width at the narrow end; (iii) a collection strip in fluid communication with the lateral flow assay strip, the collection strip having a first portion disposed within the channel and a second portion protruding outwardly from the neck portion opening; and (iv) a blocking strip coupled between and in flow communication with the lateral flow assay strip and the collection strip.

摘要： An apparatus and process for transporting aqueous fluid from the oral cavity to a lateral chromatographic strip for test is disclosed. A lateral chromatographic strip is placed within a cavity defined in a housing. The lateral chromatography strip extends within the cavity and is disposed along the housing to an inspection site. At least one inspection site to the lateral chromate phic strip is provided to enable inspection of selected sites on the lateral chromatographic strip for test results. A porous wick material protrudes from the housing to a collection site exterior of the housing at one end and communicates to the lateral chromatographic strip at the other end. This porous wick material has particulate construction, the particles adsorbing aqueous oral fluid to transport the fluid from the mouth to the lateral chromatographic strip without substantial absorption. The particles of the porous wick material are bound together to define a continuous interstitial volume for the flow of oral fluid to be transported and are treated to be hydrophilic to the adsorbed oral fluids. The porous wick material readily releases oral fluid to the lateral chromatographic strip. Prevention of reverse flow to the oral cavity from the lateral chromatographic strip naturally occurs due to the circuitous flow path of the porous wick material. By observing the lateral chromatographic strip while the entire test device is in the mouth immediate test results are obtained.

摘要： A test kit for performing a diagnostic procedure. The kit comprises a plastic base which has an upper surface. The base is formed from a plastic material and a plurality of upwardly opening nests are provided in the upper surface of the base. A test component is provided in each of the nests in a manner such that the components may be displayed and made available for use. The test components are preferably displayed in essentially the plane of the upper surface of the base and an instruction booklet is provided so as to overlie the test components at the beginning of the procedure. The arrangement of the components and the size and shape of the pages of the booklet are such that as the user follows the instructions and turns pages in the booklet, components remain hidden from view until needed in conducting the procedure. The pages of the booklet are progressively shorter from front to back in the booklet so that as the pages are turned components of the kit come into view as needed.
