摘要：An improved test device for the testing of a fluid having a cup and a cover lid,

such cover lid having a reagent test strip chamber containing a reagent test strip, a filling

chamber, and a cutting chamber. An actuation cover with a window defined therein is

positioned over the reagent test strip chamber, filling chamber and cutting chamber,

such window positioned over the color change area of the reagent test strip. The

actuation cover forms a fluid-tight seal around a first end of the reagent test strip which

protrudes into the filling chamber. A pointed member is disposed under an actuation

button in the cutting chamber. After the cup is filled with fluid and the cover lid is

positioned thereon, the operator depresses the actuation button, forcing the pointed

member through the floor of the cutting chamber to form an aperture therein. The test

device is then inverted, allowing the fluid to pass through the thus formed aperture into

the cutting chamber. When the test device is uprighted, the fluid passes into the bottom

of the filling chamber and comes in contact with the protruding first end of the reagent

test strip, such fluid to be drawn along the reagent test strip to accomplish the desired

test to cause the appropriate color change to appear on such reagent test strip visible

through the window in the actuation cover.
