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 patch comprising a support layer and an adhesive layer, wherein the adhesive layer comprises diclofenac sodium, dimethyl sulfoxide, and citric acid; a mass ratio between the diclofenac sodium and the citric acid (mass of diclofenac sodium : mass of citric acid) is 1:0.15 to 1:0.45; and a mass ratio between the diclofenac sodium and the dimethyl sulfoxide (mass of diclofenac sodium : mass of dimethyl sulfoxide) is 1:0.75 to 1:3.
摘要:
The invention regards a method of manufacturing a microneedle comprising steps of: forming a plurality of first linear grooves on a substrate (10) in parallel to one another along a first direction using grinding; and forming a plurality of second linear grooves on the substrate in parallel to one another in a second direction intersecting the first direction using grinding. At least one of the step of forming a plurality of first linear grooves and the step of forming a plurality of second linear grooves includes: forming first stage grooves using a first dicing blade (16); processing the first stage grooves by tracing the first stage grooves using a second dicing blade (17) having a side sudace different from that of the first dicing blade (16) to thereby form second stage grooves.
摘要:
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.
