A device (10) for covering and protecting the hollow needle (2) of a prefilled injection syringe (12), after the syringe (12) has been used to inject a fluid medicament into a patient, includes a guard (14) and a guard body (16). Prior to an injection, the device (10) is installed on the prefilled injection syringe (12) with the guard body (16) affixed to the finger flange (26) of the syringe (12). During the injection, the guard (14) of the device (10) retracts over the needle (22) and into the guard body (16) to allow the needle (22) to be inserted into the patient. Upon withdrawal of the needle (22) from the patient, the device (10) passively re-covers the needle (22), locking the guard (14) over the tip of the needle (22) to prevent accidental needlesticks or inadvertent re-use of the syringe (12). |
