Sampler Device
First Claim
1. A sampler device for extraction and collection of a capillary blood sample, comprising a lancet carried by a piston which is movable in a cylinder, a mechanism arranged to drive the piston for expelling of the lancet out from the cylinder in a distal direction and subsequently for retraction of the piston and the lancet in a proximal direction, opposite to said distal direction, characterized by said cylinder being arranged for collection of the blood sample, and said piston being controllable by said mechanism to travel in the distal direction for feeding a sample volume out from the cylinder.

Abstract
A sampler device for extraction, collection and delivery of a blood sample, includes a lancet (50) carried by a piston (40) which is movable in a cylinder (30), a mechanism (60,70) arranged to drive the piston for expelling of the lancet out from the cylinder in the distal direction and subsequently for retraction of the piston and lancet in a proximal direction, opposite to the distal direction, the cylinder being arranged for collection of the blood sample and the piston being controllable by the mechanism to travel in the distal direction upon feeding a sample volume out from the cylinder.

15. A sampler device for disposable use, said sampler device comprising:
-
a housing;
a cylinder, integrally formed with the housing and adapted to collect a blood sample via an opening in a distal end of said cylinder;
a piston movable in the cylinder;
a lancet carried by the piston;
a push-button acting on the piston and effective for driving said piston in the distal direction for expelling of the lancet out from the cylinder;
a return spring acting on the piston and effective for retracting said piston and the lancet in a proximal direction, opposite to said distal direction;
said housing, said push-button, said return spring, said cylinder and said piston arranged in coaxial relation, and an interlock mechanism at the interface between the housing and the push-button, controlling a relative motion there between, said mechanism being releasable in response to a relative rotation between said push-button and said housing.
