Abstract

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

Claims

1. A device operable to extract a sample of body fluid, the device comprising:

at least one skin-penetration member;

an actuator for extending and/or retracting the at least one skin-penetration member;

a controller for controlling the actuator; and

a housing for mounting the at least skin-penetration member and the actuator.
