Transdermal adhesive patch assembly with removable microneedle array and method of using same |
摘要 |
A transdermal adhesive patch assembly and method of using same. The assembly can include a backing, and an adhesive and a matrix coupled to the backing. The matrix can include an active ingredient. The assembly can further include a microneedle array in at least partially overlapping relationship with the matrix; and a carrier that couples the microneedle array to the matrix opposite the backing, wherein the carrier and the microneedle array form a skin treatment assembly that, along with the matrix, can be located on a flap. The method can include adhering at least a portion of the adhesive to skin to form an anchor; applying pressure adjacent the microneedle array to treat an area of the skin; moving the flap away from the skin; removing the skin treatment assembly to expose the matrix; and replacing the flap to position the matrix over the treated area of the skin. |

1. A transdermal adhesive patch assembly, the assembly comprising:
a backing having a first major surface and a second major surface; a skin-contact adhesive coupled to the second major surface of the backing; a matrix comprising an active ingredient, the matrix coupled to the second major surface of the backing; a microneedle array located in at least partially overlapping relationship with the matrix; and a carrier positioned to couple the microneedle array to the matrix opposite the backing, wherein the carrier and the microneedle array form a skin treatment assembly that is configured to be decoupled from the matrix, when desired, to expose the matrix; wherein a portion of the backing and at least a portion of the skin-contact adhesive extend beyond the skin treatment assembly in at least one direction to form an anchor, and wherein the matrix and the skin treatment assembly are located on a flap that is movable with respect to the anchor between a first position in which the flap is not folded back relative to the anchor and a second position in which the flap is folded back relative to the anchor. |
