Abstract
A puncturing set has a housing with a hose extension. A tubular puncturing needle is disposed inside the housing and extends axially substantially over the length of the hose extension. The needle is movable between an extended position, in which its forward, pointed end projects axially from a free end of the hose extension, and a retracted position, in which the pointed end of the needle is inside the hose extension. At the aft, downstream end of the puncturing needle is a fluid withdrawal mechanism and there is a sealing arrangement between the puncturing needle and the housing.
