Devices, systems, and methods for the containment and use of liquid solutions
First Claim
1. A liquid containment system for use with an analyte concentration measuring system including a fluid-accepting test strip, the liquid containment system comprising:
- at least one containment device including,a first flexible layer and a second flexible layer sealed together to form a hermetically sealed reservoir therebetween, wherein the reservoir includes a liquid control solution that is configured to mimic a physiological fluid, wherein the first and second flexible layers include a tearable portion extending from a first notch to a second notch both formed within the first and second flexible layers and defining a tear line between a first and second portion of the reservoir, and wherein the hermetically sealed reservoir has a volume equivalent to a single dose in the form of a single drop of the control solution upon tearing of the tearable portion; and
a third flexible layer fixedly disposed against the first or second flexible layers and adjacent to one or both of the first and second reservoir portions and configured and arranged to present a platform for receiving the single drop of the control solution and to present the single drop to the fluid-accepting test strip upon tearing of the tearable portion of the first and second flexible layers.

Abstract
Disclosed are embodiments of a containment device having a flexible first layer and a flexible second layer sealed together to form a hermetically sealed reservoir. The surface area of contact between the first and the second layers can define a frame about the perimeter of the reservoir. The containment device can also include a porous pad located within the reservoir, and a liquid control solution configured to mimic a physiological fluid contained within the porous pad within the reservoir. The containment device can include a third flexible layer presenting a liquid holding surface for a user. A portion of the first and/or second layers can function as a frangible seal that is configured to be torn away by a user.

15. A liquid containment device adapted for use with an analyte concentration measuring system including a test strip, the device comprising:
-
a first flexible layer and a second flexible layer sealed together along a seal to form a hermetically sealed reservoir therebetween, wherein the seal includes a frangible seal portion including a first notch in the first layer and a second notch in the first layer, wherein the frangible seal portion is configured to be torn by a user along a tear line in the first layer from the first notch to the second notch; and a liquid control solution that is configured to mimic a physiological fluid contained within the reservoir in a volume equivalent to a single drop of the control solution; wherein the second flexible layer is configured and arranged to present a clean platform for receiving the single drop of the control solution and adapted to present the single drop of control solution to the test strip upon tearing of the frangible seal portion of the first flexible layer. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
