Microneedle array unit

Abstract

A microneedle array unit including a microneedle array having a plurality of needle-like protrusions arranged on one surface thereof, a gripping portion provided on a side opposite to the plurality of needle-like protrusions of the microneedle array, and a container configured to accommodate the microneedle array. The container includes an accommodation portion having an opening, a deformable portion disposed on a side opposite to the opening, and a binding portion provided in the accommodation portion of the deformable portion and bound to the gripping portion of the microneedle array. The deformable portion is deformed by receiving an external force in a direction of the opening and presses the microneedle array through the gripping portion, and the microneedle array is pushed out of the accommodation portion by being pressed, and the deformable portion maintains a deformed state and presses the microneedle array.

What is claimed is: 
     
         1 . A microneedle array unit comprising:
 a microneedle array having a plurality of needle-like protrusions arranged on one surface thereof;   a gripping portion provided on a side opposite to the plurality of needle-like protrusions of the microneedle array; and   a container configured to accommodate the microneedle array,   wherein the container includes   an accommodation portion having an opening,   a deformable portion disposed on a side opposite to the opening, and   a binding portion provided in the accommodation portion of the deformable portion and bound to the gripping portion of the microneedle array,   the deformable portion is deformed by receiving an external force in a direction of the opening and presses the microneedle array through the gripping portion, and   the microneedle array is pushed out of the accommodation portion by being pressed, and the deformable portion maintains a deformed state and presses the microneedle array.   
     
     
         2 . The microneedle array unit according to  claim 1 , wherein the binding portion and the gripping portion are fitted and bound to each other. 
     
     
         3 . The microneedle array unit according to  claim 2 , wherein a claw portion provided in the gripping portion fits to a groove provided in the binding portion. 
     
     
         4 . The microneedle array unit according to  claim 1 , further comprising a lid member configured to seal the opening. 
     
     
         5 . The microneedle array unit according to  claim 1 , wherein the deformable portion is formed integrally with the accommodation portion. 
     
     
         6 . The microneedle array unit according to  claim 1 , wherein the deformable portion is formed into a convex shape with a vertex separated from the microneedle array. 
     
     
         7 . The microneedle array unit according to  claim 1 , wherein the container comprises a flange portion extending outward from a periphery of the opening of the accommodation portion.
