Disposable test device with sample volume measurement and mixing methods
First Claim
1. A sample testing device comprising:
- a volume chamber that separates a sample of known volume from a remaining sample through the introduction of a fluid in an entire sample containing both the sample of known volume and the remaining sample;
wherein the introduction of the fluid is through a fluid inlet port that has an open and closed state; and
a passage comprising;
a mixing chamber connected to the volume chamber and adapted to mix the sample;
a test chamber connected to the mixing chamber and adapted to perform a test on the sample;
a first vent port that has an open and a closed state;
wherein when the fluid inlet and first vent ports are in the open state, the introduction of a pressurized fluid into the fluid inlet port drives the sample from the volume chamber, into the mixing chamber, and then into the test chamber.

Abstract
A sample testing device has a volume chamber that separates a known volume of a sample from a remaining sample through the introduction of a fluid between the known volume of the sample and the remaining sample wherein the introduction of the fluid is through a fluid inlet port that has an open and closed state. The device further comprises a passage including a mixing chamber connected to the volume chamber and adapted to mix the sample; a test chamber connected to the mixing chamber and adapted to perform a test on the sample; and a vent port that has an open and a closed state. When the fluid inlet and vent ports are in the open state, the introduction of a pressurized fluid into the fluid inlet port drives the sample from the volume chamber, into one or more mixing chambers, and then into the test chamber.

43. A method for volume measurement, mixing, and testing a sample comprising the following steps:
-
separating an exact volume of a sample from a larger sample through the introduction of a fluid between the sample and the larger sample;
mixing the sample with a reagent;
testing the sample; and
driving the sample through each step of the method. - View Dependent Claims (44)
