Abstract

A test device for analyzing fluid samples. The test device includes a planar support member for supporting reagent pads, and a handle attached to, or for attaching to the planar support member. The test device can be treated with a fluid sample by disposing a fluid sample on the reagent pads. The fluid sample can be disposed onto the reagent pads by the handle, or by dipping the test device into the fluid sample.

First claim

What is claimed is:

1. A fluid test device, comprising:
a planar support member having a top surface, a bottom surface, and an outer peripheral edge;
one or more reagent pads disposed on the bottom surface of the planar support member in a way that at least a portion of each of the reagent pads extends from a bottommost portion of the bottom surface of the planar support member in a direction away from the top surface; and
a handle extending from the top surface of the planar support member such that the handle is disposed entirely within a zone defined by an area of space extending from an entirety of the outer peripheral edge in a direction perpendicular to the top surface and the bottom surface of the planar support member.

2. The test device of claim 1 wherein the handle is a unitary extension of the planar support member.

3. The test device of claim 1 wherein the handle is an independent member attached to the planar support member.

4. The test device of claim 1 wherein the handle extends perpendicular to the planar support member.

5. The test device of claim 1 wherein the handle is attached to the planar support member at a location interior to the peripheral edge of the planar support member.

6. The test device of claim 1 wherein the planar support member has an opening extending through the planar support member from the top surface to the bottom, and wherein the handle has a longitudinal passage extending from a proximal end of the handle, and wherein the handle extends from the planar support member such that the longitudinal passage of the handle is axially aligned with the opening of the planar support member.

7. The test device of claim 6 wherein the handle is tapered from the proximal end so that the test device is nestable with another test device.

8. The test device of claim 1 , wherein the planar support member further includes a hinge, a first end of the handle attached to the hinge.

9. The test device of claim 3 , wherein the planar support member further includes a handle dock positioned on the top surface, wherein a first end of the handle is insertable into the handle dock.

10. The test device of claim 9 , wherein the handle further includes an engagement tab located near the first end of the handle and a release mechanism located near a second end of the handle, the engagement tab engageable with the handle dock when the first end of the handle is releasably inserted into the handle dock.
