Abstract
A rotary fluid manipulator utilizable as a diagnostic device includes a porous body having fluid passages defined therein by fluid blocking means in the porosities of the body such as openings or slots in the body or compaction of areas of the porous body to define fluid passages therebetween. Various substances or binding partners such as receptors, immunoassay or other assay test materials and test specimens can be deposited on the porous body to permit various types of tests to be made by rotation of the manipulator to cause conjunctive centrifugal and wicking induced flow of fluids deposited thereupon.
Claims5
A device comprising:
- means for testing for the presence of an analyte in a liquid including:
- a. a liquid input means having a receiving inlet and a discharge aperture;
- b. filter means positioned below said liquid input means and having at least one viewable reaction zone for receiving liquid from said input means to separate any analyte therefrom and at least one peripheral zone associated with said at least one reaction zone;
- c. absorbent means associated with only said peripheral zone of said filter means for drawing said liquid from said reaction zone to said peripheral zone;
