摘要

The needle guard 26 is integral with the syringe holder 14 so as to provide no exposure, selective or otherweise, of the needle. A removable needle guard 28 is further provided. A tubing set 41 is provided with a puncture port which fits in a liquid-tight manner into the cylindrical needle guard 26. The tubing set 41 further includes anti-siphoning means and low volume tubing.
