A device (1) operable to extract a sample of body fluid, the device (1) including at least one skin-penetration member (6), an actuator (4), a controller (5), and a housing mounting the at least one skin-penetration member (6) for extension from the device (1). Another device for extracting body fluid includes at least one skin-penetration member (6) having an inner bore and an outer diameter, and at least one axially moveable hollow tubular member (14) disposed in the inner bore (or alternatively disposed around the outside of the skin-penetration member (6)). Yet another device includes at least one skin-penetration member (6), an actuator (4), a controller (5), a housing mounting the at least one skin-penetration member (6), and a skin sensor measuring electrical parameters transmitted through the at least one skin-penetration member. Associated methods are also disclosed.

L'invention concerne un dispositif permettant d'extraire un échantillon de liquide corporel et comprenant au moins un élément de pénétration cutanée, un actionneur, un contrôleur, et un boîtier montant l'élément de pénétration cutanée en vue de son extension depuis le dispositif. On prévoit un autre dispositif d'extraction de liquides corporels comprenant au moins un élément de pénétration cutanée ayant un alésage interne et un diamètre externe, et au moins un élément tubulaire creux se déplaçant axialement disposé dans l'alésage interne (ou placé selon une autre variante, autour de l'extérieur de l'élément de pénétration cutanée). On prévoit encore un autre dispositif comprenant au moins un élément de pénétration cutanée, un actionneur, un contrôleur, un boîtier montant l'élément de pénétration cutanée et un capteur cutané mesurant les paramètres électriques transmis à travers au moins un élément de pénétration cutanée. Font également l'objet de cette invention des procédés associés.
