  • Patent number: 7282181
    Abstract: A fluid collection and testing device includes a collection vial having a bottom and an open top along with an expresser sized for insertion into the vial open end. The expresser includes a ribbed base enabling fluid to pass therethrough and a support member holds the expresser within the collection vial with the ribbed base in a spaced apart relationship with the vial bottom. A fluid collector includes an absorbent member capturing a fluid and the absorbent member is sized for insertion into the expresser and is compressible against the ribbed base for releasing captured fluid through the ribbed base and into the vial bottom. A catch mechanism is provided for latching the fluid collector to the expresser after insertion into the expresser for enabling simultaneous removal of the expresser and the fluid collector from the collection vial.

  • Patent number: 6833111
    Abstract: A multiple analyte assaying device includes a casing having a pocket portion adapted to capture or contain a predetermined volume of fluid specimen to be assayed. Disposed within the casing is a sample receiving pad and one or more reagent test strips. The pocket portion of the casing includes a feed element having multiple feed inlets, or alternatively, a single feed slot. The feed element provides pressure against the sample receiving pad. The pressure against the pad and a small size of the inlet or inlets are effective in controlling a rate of fluid release of the specimen to the sample receiving pad. The casing includes observation windows or alternatively a clear plastic view area for enabling observation of reagent zones of the test strips. The device is structured and adapted to enable a technician to capture the appropriate volume of fluid specimen in the pocket portion by submerging or dipping a portion of the device into a fluid-filled collection container for a brief period of time.

  • Publication number: 20030143124
    Abstract: A well plate seal includes a matt having a plurality of spaced apart wells for engaging and sealing a plurality of exit ports in a multi-well extraction plate. Unidirectional flow control valves are disposed in each of the plurality of matt wells for enabling liquid flow out of each of the exit ports only upon application of a pressure differential across each exit port.

  • Publication number: 20020093147
    Abstract: A seal is provided for a well plate having a plurality of wells with each well having an opening in one end therein for influxing a fluid and another end thereof for effluxing the fluid. The seal includes a planar member having a top and bottom and a plurality of recess formed in the top and a plurality of cups formed in the bottom. A plurality of recesses are uniformly spaced apart from one another and each recess is sized for sealably engaging a corresponding well tip. The plurality of cups are uniformly spaced apart from another and sized for sealably engaging a corresponding well opening in order to enable the member to effect a sealed engagement with all of the well openings or all of the well tips.
