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.

Abstract: An automatic skate sharpener comprises a skate sharpening mechanism inside a cover. A skate loading device is pivotally mounted in an opening in the protective cover, so that it can be pivoted between a loading position, in which the skate is on the outside of the protective cover, and a starting position for sharpening of a skate, in which the skate is on the inside of the protective cover. The skate loading device comprises a gripping device for releasably gripping at least one skate to be sharpened, first obturation device which substantially closes the opening in the skate loading position, and second obturation device which substantially closes the opening in the starting position.
