| description | Conventional syringes typically have fixed needles which protrude forwardly from the end of the syringe barrel. Users can accidentally be nicked or pricked by the needles, risking infection. Syringes that retract needles are typically expensive and complicated. A fluid delivery injector comprises a syringe defining a barrel; a plunger and a hollow needle provided within the barrel adapted for linear movement parallel to a longitudinal axis with a distal tip of the needle contained within the syringe. A fluid retention reservoir is defined at least in the barrel and is in fluid communication with the needle when pressure is applied to the fluid in the reservoir and to the plunger for moving the needle out of the barrel.. A means for retracting the needle is provided for retracting the needle when pressure is released from the plunger. |
