PATIENT-CONTACT ACTIVATED NEEDLE STICK SAFETY DEVICE

摘要

A device that is used in conjunction with a needle-based medication injection device (e.g. a prefilled syringe) that prevents needle stick injuries after the medication has been injected into a patient. The used needle is shielded by a cylindrical needle guard that surrounds and extends beyond the needle tip. In a preferred embodiment, before the needle is inserted into the patient, the needle guard projects forward to substantially hide visibility of the needle for safety and to reduce patient anxiety.
