Abstract
A needle device including a housing. The housing includes a first housing element provided towards a proximal end of said needle device and a second housing element provided towards a distal end of said needle device. A cutting element having a sharp proximal end is arranged at a proximal end of said first housing element. A cannula having a blunt proximal end is fitted to the second housing element and an opening for the cannula is provided at the proximal end of the first housing element. The first housing element and the second housing element are moveable relative to each other between an extended position where the proximal end of the cannula does not extend beyond the proximal end of the cutting element and a compressed position where the cannula extends through the opening of the first housing element and past the proximal end of the cutting element.
