摘要

A syringe (2), comprises tubular barrel (12) with an end wall (14) to receive the needle and an inner plunger (6), has an external sliding needle protector (8) with a tube (72) which deploys to cover the needle and a projecting leg (74), extending from the tube and lying parallel to the plunger. A syringe (2), comprises tubular barrel (12) with an end wall (14) to receive the needle and an inner plunger (6), has an external sliding needle protector (8) with a tube (72) which deploys to cover the needle and a projecting leg (74), extending from the tube and lying parallel to the plunger. The projecting leg surrounds only part of the plunger, allowing the plunger to be operated separately from the needle protector.
