Abstract
Official abstract text for this publication.
An applicator according to one embodiment includes a housing having a tubular shape with one closed end, and configured to house an elastic member and a piston plate for transmitting biasing force of the elastic member to the microneedles, and release means configured to release the piston plate engaged in a manner resisting against the biasing force of the elastic member in the housing, to cause the piston plate to move toward an opening of the housing along an axial direction of the housing. The release means is configured, when the release means releases the engagement of the piston plate by moving toward the housing in the axial direction, to transmit force in a direction toward the opening to the housing.
First claim
Opening claim text (preview).
The invention claimed is: 1. An applicator for applying microneedles to skin, the applicator comprising: a housing having a tubular shape with one closed end, and configured to house an elastic member, and a piston plate for transmitting biasing force of the elastic member to the microneedles; and release means configured to release the piston plate engaged in a manner resisting against the biasing force of the elastic member in the housing, to cause the piston plate to move toward an opening of the housing along an axial direction of the housing, wherein the release means is configured, when the release means releases the engagement of the piston plate by moving toward the housing in the axial direction, to transmit force in a direction toward the opening of the housing, wherein the piston plate is provided with a hole, and the housing is provided with a protruding portion fitting inside the hole and protruding in the axial direction. 2. The applicator according to claim 1 , wherein the release means further comprises a release portion configured to release the engagement of the piston plate, and the engagement of the piston plate is released by causing the release portion to rotate the piston plate when the release means moves in the axial direction. 3. The applicator according to claim 1 , wherein the release means includes an engaging portion, and the engaging portion is configured to move in the axial direction and to become engaged with the housing when the release means releases the engagement of the piston plate. 4. The applicator according to claim 3 , wherein an eave portion is provided to an outer circumferential surface of the housing, a locked condition and an unlocked condition are switched by the release means rotating in a circumferential direction of the housing, the locked condition is a condition where the release means is prohibited from releasing the engagement of the piston plate, the unlocked condition is a condition where the release means is permitted to release the engagement of the piston plate, and the engaging portion is supported by the eave portion in the unlocked condition.
