摘要:
A conical-projections-sheet packaging body (1) includes a conical-projections sheet (23), a conical-projections forming sheet (7), and a sealing sheet (9). The conical-projections sheet (23) includes a substrate (23a) and a plurality of conical projections (23b) formed on a surface (23c) of the substrate (23a). The conical-projections forming sheet (7) has a plurality of conical-recess parts (33a), which is used to form the plurality of conical projections (23b) and wherein the plurality of conical projections (23b) is disposed. The conical-projections forming sheet (7) protects the conical projections (23b) in a state wherein the plurality of conical projections (23b) is tightly adhered to the surface (23c) of the substrate (23a). The sealing sheet (9), by being fixed to the conical-projections forming sheet (7), seals the conical-projections sheet (23) between the conical-projections forming sheet (7) and the sealing sheet (9).
摘要:
Provided are a transdermal patch and a microneedle sheet, which can efficiently introduce a target substance to the stratum corneum and prevent a reduction in the protection capability of the stratum corneum. A microneedle sheet (20) comprises a sheet-shaped base material (21) and a plurality of microneedles (50) on the sheet-shaped base material (21) making contact with a stratum corneum (110) of a skin (100). Each of the plurality of microneedles (50) includes a skin-stretching part (51) projecting from the sheet-shaped base material (21), the skin-stretching part having a tip surface (51 a) configured to stretch the stratum corneum (110) by pressing against the surface of the stratum corneum (110) of the skin (100) without sticking into the surface of the stratum corneum (110). A needlelike-projection part (52) is formed on the tip surface (51a) of the skin-stretching part (51) having a shape such that the needlelike-projection part (52) sticks into the surface of the stratum corneum and a peak part (52a) of the needlelike-projection part (52) stays inside the stratum corneum (110).
摘要:
There are provided a substrate sheet (2), a plurality of design portions (3) arranged independently from each other along a longitudinal direction of the substrate sheet and each including at least a conductive material portion (3a), and a band-shaped static eliminating band portion (5) extending continuously along the longitudinal direction of the substrate sheet and electrically connecting the conductive material portions in the plurality of design portions to each other.
