Controlled strain skin treatment devices and methods
Devices, kits and methods are used for wound healing, including but not limited to the treatment, amelioration, or prevention of scars and/or keloids, and include packaging, manipulation elements, applicator and/or tensioning device that are used to apply and/or maintain a strain in an elastic dressing.
1. A scar ameliorization system comprising:
a frame comprising a rectangular window;
a strainable skin treatment device comprising an elastic sheet and removably coupled around a perimeter of a skin interfacing side of the frame so that the elastic sheet is covering the window; and
a rigid straining device comprising a handle with a rectangular protruding element configured to push orthogonally through the window of the frame on the skin interfacing side and protrude from an opposite side of the frame when the handle abuts the skin interfacing side of the frame to strain the strainable skin treatment device.
2. The system of claim 1 , further comprising an attachment structure comprising at least one extension sheet, wherein the strainable skin treatment device is coupled to the frame with the at least one extension sheet.
3. The system of claim 2 , further comprising a release element configured to release the at least one extension sheet from the strainable skin treatment device.
4. The system of claim 3 , wherein the release element comprises a perforation in the at least one extension sheet.
5. The system of claim 2 , wherein the at least one extension sheet is less elastic than the strainable skin treatment device.
6. The system of claim 1 , wherein the strainable skin treatment device comprises a skin adhesive on a skin interfacing side of the elastic sheet.
7. A method for ameliorating scar formation in a closed wound using a scar ameliorization system comprising:
a frame comprising a rectangular window;
a strainable skin treatment device comprising an elastic sheet and removably coupled around a perimeter of a skin interfacing side of the frame so that the elastic sheet is covering the window; and
a rigid straining device comprising a handle with a rectangular protruding element configured to push orthogonally through the window of the frame on the skin interfacing side and protrude from an opposite side of the frame when the handle abuts the skin interfacing side of the frame to strain the strainable skin treatment device;
the method comprising the steps of:
straining the elastic sheet attached to the frame by a predetermined amount by pushing the rectangular protruding element attached to the handle through the rectangular window of the frame until the handle abuts the frame;
adhering the elastic sheet to a skin of a subject adjacent a previously closed wound; and
releasing the skin treatment device from the frame.
