• a needle module, wherein the needle module comprises a needle unit, a housing and a biasing mechanism,
• wherein the needle unit comprises a needle, wherein said needle unit is movable with respect to said housing between an extended position wherein a distal end of the needle extends from a distal end of said housing and a retracted position wherein the distal end of the needle is positioned within the housing,
• wherein the biasing mechanism is arranged for urging the needle unit towards the retracted position, and
• wherein the device further comprises a limiting mechanism, wherein the limiting mechanism is arranged for limiting the relative movement of the needle unit out of the distal end of the housing to a maximum extension distance when moving towards the extended position, wherein said maximum extension distance is 1.5 mm or less.
