BODY FLUID SAMPLING CONSTRUCTIONS AND TECHNIQUES

摘要

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.
