To provide an applicator that can achieve a further reduction in size and weight. An applicator A1 includes a casing 10, a piston plate 20, a microneedle array 30, a conical coil spring 40, and a release member 50. The casing 10 includes: a tubular main body part 12 that houses therein the piston plate 20 and the conical coil spring 40; and a cover part 14, the cover part 14 and the piston plate 20 sandwiching the conical coil spring 40 therebetween. The main body part 12 includes interior inner walls 12b 1 to 12b 4 that lock the piston plate 20 with the casing 10 by means of projections 20c 1 to 20c 4 . The main body part 12 includes groove parts G1 to G4 that extend in the top-bottom direction. The piston plate 20 is guided in the axial direction of the main body part 12 by the groove parts G1 to G4. If a locked state of the piston plate 20 is released by the release member 50, the piston plate 20 is moved, by the biasing force of the conical coil spring 40, along the groove parts Gl to G4 inside of the main body part 12 to reach a position for action on a skin.

A puncture device which can be made smaller in size and lighter in weight and a method for manufacturing the same are provided. A puncture device 1 is a device for transferring an active ingredient into a body through a skin. The puncture device 1 comprises a tubular housing H, a piston P slidably arranged within the housing H, and a conical coil spring 40 arranged within the housing H and providing the piston P with a biasing force. The piston P has a piston body 20 and a microneedle member 30 engaging the piston body 20 so as to integrate therewith. The microneedle member 30 has a base 31 and a plurality of microneedles projecting from a surface of the base 31.

An applicator A is configured to transfer an active ingredient into a body through skin by a puncture in the skin with microneedles 32. The applicator A includes a piston plate 20 that is provided with a protrusion part 33 and protrusion parts 20d 1 to 20d 4 on a lower surface side of a main body 20a of the piston plate. The microneedles 32 are provided on a surface of the protrusion part 33. The protrusion parts 20d 1 to 20d 4 are provided in a periphery of the protrusion part 33 while spaced apart from the protrusion part 33.

An applicator of one aspect for applying a sheet member to skin includes a body having a bottom surface facing the skin and a first guide configured to guide the sheet member to a space between the skin and the bottom surface, in which the sheet member is applied to the skin after being folded in the space.
摘要:
A microneedle array in accordance with one embodiment comprises at least a first microneedle and a second microneedle that are inclined with respect to a support face. A tip of the first microneedle points in a first direction, and a tip of the second microneedle points in a second direction different from the first direction. The first microneedle in contact with skin is stuck into the skin while being moved along a surface of the skin in the first direction. The second microneedle in contact with the skin is stuck into the skin while being moved along the surface of the skin in the second direction.
