  • Lateral flow filter devices for separation of body fluids from particulate materials
    Patent number: 5916521
    Abstract: The invention relates to a filter device for use in diagnostic assay procedures for the effective separation of unwanted particulate matter from the liquid sample of an analyte. The device comprises plural sheet-like cappillary forms prepared from porous media, and that are able to receive and filter the liquid sample. The filter is so configured that, as the pores of the porous media become blocked, the liquid and any particulate matter contained therein are able to travel laterally, and then transversly, to unblocked regions of pores, thereby facilitating optimal speed and efficiency of sample processing. The invention extends to test kits for medical technologists that embody the filter device, and to corresponding methods of testing comprising the separation of particulate matter from samples such as body fluids and the like.
