Filed:

Jul 15, 2009

Appl. No.:

12/503665

Inventors:

Gregory M. Colella - Montclair NJ, US
Henry D. Huang - Edison NJ, US
Dimitri V. Shishkin - Whippany NJ, US
Maria Figueroa - Elizabeth NJ, US
James A. Mawhirt - Brooklyn NY, US

Assignee:

International Technidyne Corporation - Piscataway NJ

International Classification:

G01N 33/49
B01L 3/00

US Classification:

422 73, 422102

Abstract:

An apparatus for measuring blood clotting time includes a blood clot detection instrument and a cuvette for use with the blood clot detection instrument. The cuvette includes a blood sample receptor-inlet; a channel arrangement including at least one test channel for performing a blood clotting time measurement, a sampling channel having at least one surface portion that is hydrophilic, communicating with the blood sample receptor-inlet and the at least one test channel, and a waste channel having at least one surface portion that is hydrophilic, communicating with the sampling channel; and a vent opening communicating with the sampling channel. The sampling channel, the vent opening and the waste channel, coact to automatically draw a requisite volume of a blood sample deposited at the blood receptor-inlet, into the sampling channel. More specifically, air compressed within the blood clot detection instrument, the at least one test channel of the cuvette, and the section of the sampling channel extending beyond the vent opening of the cuvette, coacts with the waste channel to cause a leading edge of the blood sample drawn into the sampling channel from the blood receptor-inlet, to pull back within the sampling channel and uncover an optical sensor in of the blood clot detection instrument. The uncovering of the optical sensor activates a pump module of the blood clot detection instrument, which draws the requisite volume of the blood sample into the at least one test channel.
