Title (EN) MICRONEEDLE
(FR) MICRO-AIGUILLE
(JA) マイクロニードル
Abstract:
(EN) This microneedle is provided with: a base part having a supporting surface; and a projection part that protrudes from the supporting surface and has a through hole that penetrates through the projection part in the direction in which the projection part extends. The projection part has a flow channel expansion part that is configured such that a communicating path, by which the space within the through hole and the space surrounding the projection part are in communication with each other, is expanded with an increase in the pressure of a fluid flowing in the through hole.
(FR) La présente invention concerne une micro-aiguille comportant : une partie de base ayant une surface de support ; et une partie saillante qui fait saillie à partir de la surface de support et présente un trou traversant qui pénètre à travers la partie saillante dans la direction dans laquelle s'étend la partie saillante. La partie saillante comporte une partie d'extension de canal d'écoulement qui est conçue de telle sorte qu'un chemin de communication, par lequel l'espace à l'intérieur du trou traversant et l'espace entourant la partie saillante sont en communication l'un avec l'autre, est agrandi avec une augmentation de la pression d'un fluide s'écoulant dans le trou traversant.
(JA) マイクロニードルは、支持面を有する基体部と、支持面から突き出た突起部であって、当該突起部の延びる方向に沿って当該突起部を貫通する貫通孔を有する突起部とを備えている。突起部は、貫通孔内の空間と突起部を取り囲む空間とを連通させる連通路を、貫通孔を流れる流体の圧力の増加に伴って広げるように構成された流路拡張部を有する。
