摘要
Devices for transferring fluid to or from a subject include an elongate tubular cannula having opposing proximal and distal ends with an axially extending lumen. The devices also include an elongate needle having opposing proximal and distal ends. The elongate needle is configured so that the distal end of the needle extends out of the distal end of the cannula a suitable adjustable distance. The devices also include a housing with a length adjustment mechanism that adjusts a length between the tip of the needle and the distal end of the tubular cannula.
