A device for withdrawing or delivering a substance through the skin of a patient includes a body (12) and a skin penetrating device (14) having a plurality of skin penetrating members, such as microneedles. The body includes a bottom surface having a first inner surface area (32) supporting the skin penetrating members and a second outer surface (34) having an adhesive (38) for attaching the device to the skin. In one embodiment, the first inner surface is spaced outwardly from the second outer surface when the device is attached to the skin. The inner surface can have a textured visually wettable surface, such as an etched surface, to provide a visual indication of leakage from the interface between the skin penetrating members and the skin.
L'invention concerne un dispositif permettant de prélever ou d'administrer une substance à travers la peau d'un patient. Ce dispositif comprend un corps (12) et un dispositif de pénétration cutanée (14) doté d'une multitude d'éléments de pénétration cutanée, tels que des micro-aiguilles. Le corps comprend une surface inférieure présentant une première surface efficace interne (32) qui maintient les éléments de pénétration cutanée et une seconde surface externe (34) pourvue d'un adhésif (38) qui permet la fixation du dispositif sur la peau. Dans un mode de réalisation, lorsque le dispositif est fixé sur la peau, la première surface interne est écartée vers l'extérieur de la seconde surface externe. La surface interne peut présenter une surface texturée visuellement mouillable, telle qu'une surface gravée, de manière à constituer une indication visuelle de fuite depuis la zone de contact entre les éléments de pénétration cutanée et la peau.
