摘要：
A syringe needle safety apparatus comprising a syringe barrel having an open end and an opposite end adapted for a needle and a needle safety cover displaceable between a un-deployed state wherein the cover is constrained and the needle exposed, and a deployed state wherein the cover covers at least the needle tip. A plunger is slidably engaged in the syringe barrel and at least one element secures the needle safety cover in the un-deployed state. Biasing means urge the needle safety cover from the un-deployed state to the deployed state, and a housing is coupled to the opposite end of the syringe barrel, the housing comprising a corresponding securing member and a deformable member, the deformable member releasing the at least one element from the corresponding securing member upon receiving a releasing force via the plunger. During deployment, the needle safety mechanism provides for the needle safety cover to avoid contact with the needle, reducing or eliminating blood contact.
