Abstract

Un dispositif de transport de fluides à travers une barrière biologique comprend une pluralité de microaiguilles qui partent de la face avant d'un substrat. Un conduit est associé à chacune des microaiguilles pour assurer un chemin d'écoulement pour le fluide permettant de transporter du fluide dans un trou ménagé dans la barrière biologique formé par la microaiguille correspondante. Chaque microaiguille est configurée pour comprendre une pointe perforante et chaque conduit débouche dans une ouverture qui est proximale par rapport à la pointe de la microaiguille. On décrit également des dispositifs à microaiguilles ayant des configurations de pompage à structure micro-électromécanique (MEMS) qui enlèvent et/ou apportent des fluides et des systèmes de soins de santé éloignés fondés sur de tels dispositifs.
