Textured apparatus with therapeutic material incorporated therein and methods of manufacturing same
A device that fits on a person's finger to reduce the effect, appearance, and/or sensitivity of a scar. The device includes a therapeutic material such as a therapeutic cream that can be released upon the application of heat such as frictional heat generated during use of the device. The device can also be used as an applicator to distribute and work therapeutic material into the scar after the therapeutic material has been placed directly onto the scar tissue. A method of manufacturing the device includes mixing the therapeutic material, a moldable material, and an optional curing agent to form a compound material, molding the compound material, heating the compound material or the molded structure, and curing the molded structure. Alternatively, the curing agent can be absorbed into the cured structure.
1. An apparatus for treating skin, the apparatus comprising:
a substantially cylindrically shaped body having an axial length and a width and having a wall of a finite thickness, and defining a cylindrical cavity suited to receive a finger, said wall having an interior surface defined by said cavity, as well as an exterior surface;
said body further having a first end and a second end at opposing ends of said axial length of said body, said first end comprising an aperture to allow a finger to pass through said aperture and into the cavity along said axial length, and the interior surface of the second end conforms to a tip of a finger;
said body additionally comprising at least one side opening in a side of said wall; and
a textured region defined on at least a portion of the exterior surface of the body, the textured region comprising raised features extending from the exterior surface of the body, the raised features having an elongated shape, wherein a first group of the raised features is oriented in a first direction and a second group of the raised features is oriented in a second direction, the second direction orthogonal to the first direction,
wherein the body is formed by a molded compound material that includes a therapeutic material and a moldable material,
wherein the therapeutic material comprises a therapeutic cream configured to treat scar tissue.
2. The apparatus of claim 1 , wherein the compound material is configured to release a portion of the therapeutic material when heated above room temperature.
3. The apparatus of claim 1 , wherein the textured region includes a grid having a first section comprised of the first group of the raised features and a second section comprised of the second group of the raised features, the first section adjacent to the second section.
4. The apparatus of claim 1 , wherein the moldable material comprises silicone.
5. The apparatus of claim 1 , wherein the molded compound material includes a range of about 1% by weight to about 15% by weight of the therapeutic material and a range of about 85% by weight to about 99% by weight of the moldable material.
6. A method for manufacturing an apparatus, comprising:
mixing a therapeutic material and a moldable material to form a mixed material, the therapeutic material for treating a dermatological condition;
molding the mixed material to form a molded structure that comprises:
a substantially cylindrically-shaped body having an axial length and a width and having a wall of a finite thickness, and defining a cylindrical cavity suited to receive a finger, said wall having an interior surface defined by said cavity, as well as an exterior surface; and
a textured region defined on at least a portion of the exterior surface of the body, the textured region comprising raised features extending from the exterior surface of the body, the raised features having an elongated shape, wherein a first group of the raised features is oriented in a first direction and a second group of the raised features is oriented in a second direction, the second direction orthogonal to the first direction; and
curing the molded structure to form the apparatus,
wherein the therapeutic material comprises a therapeutic cream configured to treat scar tissue.
7. The method of claim 6 , further comprising mixing a curing agent with the therapeutic material and the moldable material.
8. The method of claim 7 , wherein the curing agent comprises platinum or a peroxide.
9. The method of claim 8 , wherein the molding step includes heating the mixed material to a temperature within a range of about 300° F. to about 350° F.
10. The method of claim 7 , wherein the curing agent comprises platinum or tin.
11. The method of claim 10 , wherein the molding step includes heating the mixed material to a temperature within a range of about 100° F. to about 225° F.
12. The method of claim 6 , wherein the molding step includes heating the mixed material to a temperature within a range of about 60° F. to about 120° F. and the curing step includes exposing the molded structured to ultraviolet light.
13. The method of claim 6 , further comprising mixing the therapeutic material and the moldable material in a static mixer.
14. The method of claim 13 , further comprising pumping the therapeutic material and the moldable material into the static mixer.
15. The method of claim 6 , wherein the moldable material comprises silicone.
16. The method of claim 6 , wherein the molding step includes injection molding or compression molding.
