摘要:
A product having a microneedle array is provided wherein the composition distribution has been adjusted with good accuracy. A droplet-delivery apparatus (10) of a microneedle-array manufacturing apparatus (1) is configured capable of delivering, to each recessed part, droplets of a raw-material liquid in a prescribed amount that is less than the capacity of the recessed part. An aligning apparatus (20) can align the relative position of the droplet-delivery apparatus (10) and a mold (80) such that the droplets from the droplet-delivery apparatus (10) are caused to land in each of the recessed parts. The droplet-delivery apparatus (10) delivers a plurality of the droplets to each of the recessed parts; and the aligning apparatus aligns the relative position of the droplet-delivery apparatus and the mold such that a second droplet lands in each of the recessed parts on the center part side of a first droplet.

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:
A low cost transdermal patch, which comprises water soluble microneedles and has good performance, and a method of manufacturing the same are provided. A transdermal patch (1 E) comprises a microneedle sheet (310), which comprises a plurality of water soluble microneedles (311), moisture permeable sheet (320), wherethrough water vapor passes, and a reinforcing film (30E). The reinforcing film (30E) is adhered, by an adhesive layer (35) having an adhesive strength less than that of an adhesive layer (322), onto an outer surface (320b) of the moisture permeable sheet (320), which is the side opposite the skin opposing surface (320a). The reinforcing film (30E) includes a water vapor barrier sheet (31), which blocks the passage of water vapor through at least a first area (Ar1), and a removable portion (32) around the water vapor barrier sheet (31). The removable portion (32) is configures such that it can be separated from and peeled off the water vapor barrier sheet (31).
摘要:
A microneedle patch with which a treatment is reliably completed in a short time when a microneedle is administered into skin or mucous membrane is provided. A microneedle patch (100F) includes a base member (101) and a plurality of microneedles (103g) supported by the base member (101). Each microneedle (103g) includes a top-section layer (104) comprising a biologically active substance to be inserted in dermis (310), and an intermediate layer (106) provided between the top-section layer (104) and the base member (101), having a composition having breaking strength weaker than breaking strength of a composition of the top-section layer (104), and having a thickness of 5 µm and 100 µm inclusive.
