Liquid transfer device

A liquid transfer device comprising:

• a body having a wall defining and enclosing a cavity within the body;
• two hollow conduits extending from the cavity through the wall with at least a portion of each conduit projecting outwardly from the body;
• two lengths of resilient tubing wherein the proximal end of each tubing extends through the body and is attached in fluid flow communication to one of the hollow conduits within the cavity of the body;
• two inclined planes commonly inclined, spaced apart and fastened within the cavity of the body;
• two compression blocks secured to the body within the cavity, spaced apart and spaced from the inclined planes;
• a roller clamp having at least a portion thereof extending through the wall of the body, which roller clamp is adapted to travel between the inclined planes and compression blocks having two cams which engage the inclined planes and the two resilient tubes extending through the body such that travel of the roller along the inclined planes exerts a compressive force simultaneously against the resilient tubes;
• and
• a double lumen needle releasably attached to the body and engaging the outwardly projecting portions of the two hollow conduits such that each lumen within the needle is in fluid flow communication with a resilient tube extending through the body.
