Protective cap for hypodermic syringe

摘要

A protective cap is provided for a hypodermic syringe. The protective cap is hingedly connected to the distal end of the hypodermic syringe for rotation relative thereto. In a first rotational orientation the protective cap sealingly engages a passageway extending through the distal end of the hypodermic syringe. In a second rotational orientation the protective cap enables complete access to the passageway extending through the distal end of the hypodermic syringe and into the chamber. The protective cap can be separately mounted to the hypodermic syringe or unitarily formed therewith. Preferably, the protective cap is configured to enable easy one-handed and opening and closure by a health care worker.
