Method and apparatus for applying a topical solution

1. A method for storing, mixing, and applying a solution having a first component and a second component which inhibits exposure of the first and second components to air and moisture until just prior to application, said method comprising:

hermetically sealing the first component within a first at least one ampoule;

hermetically sealing the second component within a second at least one ampoule;

disposing the first at least one ampoule and the second at least one ampoule within a hollow body, the hollow body having:

a head for dispersion of the solution;

a first breaking mechanism having a projection extendable into an interior of the hollow body; and

a second breaking mechanism, the first breaking mechanism and the second breaking mechanism disposed on a side of the hollow body, the first breaking mechanism aligned with the second breaking mechanism;

activating the first breaking mechanism such that the projection applies a force to break the first at least one ampoule and the second breaking mechanism to break the second at least one ampoule and release the first and second components from the first at least one ampoule and the second at least one ampoule; and

topically applying the solution having the first and second components through the head.

2. The method of claim 1 , wherein the first at least one ampoule comprises two ampoules and the second at least one ampoule comprises two ampoules.

3. A method for storing, mixing, and applying a solution having a first component and a second component which inhibits exposure of the first and second components to air and moisture until just prior to application, the first component being hermetically sealed within a first at least one ampoule, the second component being hermetically sealed within a second at least one ampoule, the first at least one ampoule and the second at least one ampoule disposed within a hollow body having a head for dispersion of the solution, a first breaking mechanism having at least one projection extendable into an interior of the hollow body to break the first at least one ampoule, and a second breaking mechanism to break the second at least one ampoule, the first breaking mechanism configured to rotate about a first pivot point in a plane in a first direction and the second breaking mechanism configured to rotate about a second pivot point in the plane in a second direction opposite the first direction, the first breaking mechanism and the second breaking mechanism disposed on a side of the hollow body, the first breaking mechanism aligned with the second breaking mechanism, the method comprising: activating the first breaking mechanism such that the at least one projection applies a force to break the first at least one ampoule and the second breaking mechanism to break the second at least one ampoule and mix the first and second components from the first at least one ampoule and the second at least one ampoule; and topically applying the solution having the first and second components through the head.

4. The method of claim 3 , wherein the topically applying comprises topically applying the solution to actinic keratosis.

5. The method of claim 3 , wherein activating the first breaking mechanism comprises breaking four ampoules.

6. The method of claim 3 , wherein activating the first breaking mechanism and the second breaking mechanism comprises mixing 5-aminolevulinic acid and a liquid diluent for 5-aminolevulinic acid.

7. The method of claim 3 , wherein activating the first breaking mechanism and the second breaking mechanism comprises activating two buttons.

8. The method of claim 3 , further comprising indicating an amount of solution remaining via an indicator.

9. The method of claim 3 , further comprising controlling dispersion of 5-aminolevulinic acid from the head.

10. The method of claim 3 , wherein one of the first at least one ampoule and the second at least one ampoule is configured to store contents having a volume of about 0.75 ml to about 2.25 ml, and another of the first at least one ampoule and the second at least one ampoule is configured to store contents having a weight of about 0.17 mg to about 0.52 mg.

11. The method of claim 3 , wherein activating the first breaking mechanism comprises causing a button to rotate about the first pivot point to cause the at least one projection to press against the first at least one ampoule.

12. The method of claim 1 , further comprising providing a filter to prevent broken parts of the first at least one ampoule and the second at least one ampoule from exiting the head.

13. The method of claim 3 , further comprising repeating the topical application of the solution.

14. The method of claim 3 , wherein the solution is topically applied to an internal surface or an external surface of a patient.

15. The method of claim 7 , wherein the two buttons are connected.
