Abstract
A device for sucking an effusion fluid from the skin of an organism from which keratin has been removed. A disk is received in the cavity of a cell for sucking an effusion fluid in contact with the surface of an organism. Guide grooves are formed in the surface of the disk facing a suction port while holes are formed through the disk in each guide groove. The disk allows a minimum of fluid to remain thereon and guides the fluid toward the suction side in order to enhance efficient collection. When the fluid is collected a plurality of times, the preceding fluid and the following fluid are prevented from being mixed together, insuring accurate measurement.
Claims28
A device for sucking and collecting an effusion fluid from an organism, comprising:
- a suction cell comprising a suction port for causing the effusion fluid to effuse from the organism by evacuation, and a cavity formed in an end of said suction cell for directly contacting a surface of the organism;
- a first disk received in said cavity and for directly contacting the surface of the organism;
- wherein said first disk is formed with a plurality of guide grooves on a surface thereof facing said suction port, and a plurality of through holes in said plurality of guide grooves;
- and
- a second disk interposed between said first disk and said suction port, said second disk covering open ends of said plurality of grooves and formed with a through bore aligned with said suction port.
A device for sucking and collecting a liquid effused from a surface of a multicellular organism comprising:
- a suction cell having a suction port;
- a cavity in an end of said suction cell, said cavity in communication with said suction port;
- a disk with at least one guide groove on a suction cell side of said disk, whereby said guide groove for guiding said liquid effused from said surface of said multicellular organism through at least a portion of said cavity;
- a plurality of through-holes through said disk, said through-holes providing communication between said suction cell side of said disk to an opposite side;
- and
- a cover disk on said suction cell side of said disk with at least one guide groove, said cover disk having a lumen in communication with said suction port said cover disk providing a cover on said at least one guide groove.
