Abstract

The invention relates to a jig for microneedle array placement that is provided with a main jig body with through holes through which the microneedles of the microneedle array will pass and a guiding part that guides the microneedle array to be incorporated into the main jig body and leads the microneedles into the through holes, and a microneedle array device using the jig for microneedle array placement. The invention prevents the deformation of the skin surface during puncture and allows penetration of the microneedles to the prescribed depth under the skin.

Claims

1. A jig for microneedle array placement comprising:

a main jig body having through holes for penetration of microneedles of a microneedle array;

a guiding part for guiding said microneedle array incorporated in said main jig body, so that said microneedles are lead to said through holes, and

an adhering part provided on a surface of said main jig body.

2. The jig for microneedle array placement as claimed in claim 1, wherein:

said main jig body is provided with microneedle array holders for holding said microneedle array incorporated in said main jig body.

3. The jig for microneedle array placement as claimed in claim 2, wherein:

said microneedle array holders comprise latches placed to be opposing to each other in said main jig body.

4. The jig for microneedle array placement as claimed in claim 3, wherein:

said main jig body is provided with belt connecting holes for connecting fastening belts.

5. A microneedle array device comprising:

the jig for microneedle array placement as claimed in claim 1; and

a microneedle array incorporated and fixed in said jig for microneedle array placement, wherein,

said microneedle array comprises microneedle units held by a needle holder, in a state of being sandwiched and fixed between an upper case, and a lower case having a medicinal solution inlet.

6. The microneedle array device as claimed in claim 5, wherein:

said upper case has grooves formed for guiding the both ends of said microneedle units.

7. The microneedle array device as claimed in claim 6, wherein:

said microneedle unit is provided with flow channel bosses, and is fixed by inserting said flow channel bosses into through holes formed in said needle holder.

8. The microneedle array device as claimed In claim 7, wherein:

said lower case is provided with a plurality of projections for preventing deformation of said needle holder, and spaces between said plurality of projections serve as flow channels.
