Abstract

Methods and systems are disclosed for phototreatment in which replaceable containers comprising one or more adjuvant (consumable or re-useable) substances are employed. The adjuvant substance can be, for example, a topical substance or a coolant. Systems are disclosed for using a topical substance to detect contact of a phototreatment device with a tissue, detect speed of a phototreatment device over the tissue, detect regions of tissue that have been treated by a phototreatment device and/or to provide other benefits to the tissue such as improved skin tone and texture, tanning, etc. Safety systems are also disclosed that ensure that a proper consumable substance and/or container is connected to a phototreatment device and/or directed to a proper target. Additionally, cooling systems and methods that utilize phase change materials for extracting heat from a light generating device are disclosed.

Claims

1. A phototreatment device, comprising:

a radiation source to effect a phototreatment on a region of tissue;

an applicator configured and arranged to deposit a marker in at least a portion of the region;

a detector assembly to detect the marker, and to selectively deactivate the radiation source in response to the presence of the marker.

2. The phototreatment device of claim 1, wherein the detector is one of an optical detector, an electronic detector, a mechanical detector, and a magnetic detector.

3. The phototreatment device of claim 1, wherein the detector assembly is configured and arranged to detect a reflected portion of light from an object, and to determine if the object is a tissue.

4. A method of operating a phototreatment device comprising:

applying a marker to a region of tissue;

detecting the marker; and

enabling a function of the phototreatment device when the marker is detected.

5. The method of claim 4, further comprising disabling said function until said marker is detected.

6. The method of claim 4, further comprising disabling said function when said marker is not detected.

7. The method of claim 4, wherein the marker is one of an absorptive marker, a fluorescent marker, an electric marker, and a magnetic marker.

8. The method of claim 4, wherein the marker comprises at least one of Food Blue, Toluidine Blue, Brilliant Green, Indigo Carmine, Fast Green, Erioglaucine, Methylene Blue, and Indocyanine Green;

carbon particles;

china ink;

Cu ions, Fe ions, Au ions, Ag ions, and Zn ions, Eosin Y;

an opening in fluid communication with the interior cavity of said compartment and configured to be coupled to a phototreatment device; and

a detection mechanism configured to the be coupled to a corresponding detection mechanism of the photocosmetic device.

10. The container of claim 9, wherein the compartment is fluidly coupled to a head of a phototreatment device.

11. The container of claim 9, wherein the compartment is fluidly coupled to a heat dissipating element in a phototreatment device.

12. The container of claim 9, wherein the compartment is in fluid communication with a tissue.

13. The container of claim 9, wherein the detection mechanism is one of a mechanical mechanism, an optical mechanism, a magnetic mechanism, an electronic mechanism, and a piezoelectronic mechanism.

14. The container of claim 9, wherein the detection mechanism indicates an aspect of the container.

15. The container of claim 9, wherein the detection mechanism indicates an aspect of the substance.

16. The container of claim 9, wherein the container is detachable from the photocosmetic device.

17. The container of claim 9, wherein the container is configured to be refillable.

18. The container of claim 9, wherein the container is configured to be reusable.

19. The container of claim 9, wherein the container is configured to be removable.

20. A subassembly for use with a phototreatment device to treat a tissue, comprising:

a container comprising an indicia, the container capable of being coupled to the phototreatment device; and

an indicia detector configured and arranged to detect the indicia.
