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.
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.
摘要:
Provided is an inexpensive microneedle array with little dimensional error that can control, with high precision, the amount of a predetermined component to be introduced to the inner part of the skin, and a production method for this microneedle array. A foundation (14) that is insoluble or sparingly soluble in a raw material liquid (200) is overlaid on a mold (50). A plurality of frustum-shaped protrusions (14), which are insoluble or sparingly soluble in the raw material liquid (200), provided on a first main surface (14a) of the foundation (14) are fit into a plurality of cone-shaped recesses (51). The raw material liquid (200) in the plurality of cone-shaped recesses (51) dries and, as a result, a plurality of microneedles, which are dissolvable in the inner part of the skin, are fixed to tip surfaces of the plurality of frustum-shaped protrusions.
