The present disclosure provides an apparatus including a first chamber containing an eye-mountable device. The apparatus may also include a second chamber containing an aqueous solution. The apparatus may also include a membrane positioned between the first chamber and the second chamber. The membrane may be configured to rupture based on application of a force to the apparatus. The ruptured membrane may allow the aqueous solution to engage with the eye-mountable device. The apparatus may also include a lid to seal one or more of the first chamber and the second chamber.
1. An apparatus comprising:
a cavity having an inner surface and an opening;
a membrane disposed within the cavity and extending from the inner surface to the opening;
wherein the membrane divides the cavity into a first chamber and a second chamber;
wherein the first chamber contains an eye-mountable device;
wherein the second chamber contains an aqueous solution;
wherein the membrane is configured to rupture based on application of a force to the apparatus, and wherein the ruptured membrane allows the aqueous solution to engage with the eye-mountable device; and
a lid configured to seal the opening.
2. The apparatus of claim 1 , wherein the aqueous solution includes a preconditioning solution.
3. The apparatus of claim 1 , wherein the aqueous solution includes a disinfecting solution.
4. The apparatus of claim 1 , wherein the eye-mountable device contains an analyte sensor embedded in the eye-mountable device.
5. The apparatus of claim 4 , wherein the aqueous solution includes a calibration solution, and wherein the calibration solution has a known analyte concentration.
6. The apparatus of claim 1 , wherein the lid is connected to the membrane, and wherein one or more of the lid and the membrane are configured to be at least partially removed based on application of the force.
7. The apparatus of claim 1 , wherein the first chamber is positioned adjacent to the second chamber.
8. The apparatus of claim 1 , wherein the membrane is pre-stressed so as to weaken the membrane.
9. The apparatus of claim 1 , wherein a thickness of the membrane is less than about 250 micrometers.
10. The apparatus of claim 1 , wherein the membrane includes a polymeric material.
11. An apparatus comprising:
a container having external surfaces and a cavity therein, the cavity having an inner surface and an opening;
a membrane disposed within the cavity and extending from the inner surface;
wherein the membrane divides the cavity into a first chamber and a second chamber, wherein the first chamber contains an eye-mountable device, wherein the second chamber contains an aqueous solution, and wherein the membrane is configured to rupture based on application of a force to the apparatus to allow the aqueous solution to engage with the eye-mountable device; and
a lid configured to seal the opening.
12. The apparatus of claim 11 , wherein a thickness of the external surfaces is at least about 10 times greater than a thickness of the membrane.
13. The apparatus of claim 11 , wherein the membrane is pre-stressed so as to weaken the membrane.
14. The apparatus of claim 11 , wherein the first chamber is positioned adjacent to the second chamber.
15. The apparatus of claim 11 , wherein the first chamber is positioned above the second chamber.
16. A method comprising:
providing a container having an inner surface, and an opening;
providing an eye-mountable device in a first chamber of the container;
providing an aqueous solution in a second chamber of the container;
providing a membrane within the container to divide the container into the first chamber and the second chamber, wherein the membrane extends from the inner surface to the opening, and wherein the membrane is configured to rupture based on application of a force to the container to enable the aqueous solution to engage with the eye-mountable device; and
providing a lid configured to seal the opening of the container.
17. The method of claim 16 , further comprising applying a tensile stress to the membrane so as to weaken the membrane.
18. The method of claim 16 , wherein the first chamber is positioned adjacent to the second chamber.
