Problems solved by technology

However, the length of the protrusion is shorter than that of an injection needle, so if only the protrusion is pressed against the skin, it may be difficult to puncture the protrusion to a desired depth due to deformation of the skin.

Abstract

Provided is a puncture implement for a microneedle, comprising: a clamping part (11), further comprising a first clamping element (11a) and a second clamping element (11b) which are aligned along an array direction (Da) and which respectively hold skin along a clamping direction (Dh) which intersects the array direction (Da), wherein the first clamping element (11a) and the second clamping element(11b) are coupled such that a distance (Dist) between the first clamping element (11a) and the second clamping element (11b) is maintained within a prescribed range; and a puncture part (12), which,while holding skin along the clamping direction (Dh), punctures the skin between the first clamping element (11a) and the second clamping element (11b) in the array direction (Da), said puncture part(12) further comprising a microneedle (12a) which punctures the skin and a support portion (12b) which supports the microneedle (12a).

Description

technical field [0001] The present invention relates to a microneedle puncture device for puncturing a skin with a microneedle. Background technique [0002] As a method of administering medicines such as vaccines into the body, a method using microneedles is known. The microneedles have needle-shaped protrusions whose length does not reach nerve cells in the dermis of the skin. Therefore, in the drug administration method using the microneedle, compared with the drug administration method using the injection needle, it is possible to suppress the pain at the time of puncturing the skin. In addition, in the drug administration method using microneedles, the drug is administered into the skin where antigen-presenting cells are abundantly present, so compared with the method of subcutaneously administering the drug using an injection needle, there is a problem that the drug can be reduced. Possibility of dosing. [0003] When administering a drug intradermally using a micro...
