Abstract
An apparatus for use with a syringe for providing a safety syringe, the apparatus including a sheath (100; 300; 500) deployable for at least partially covering a needle (126) of the syringe; and a sheath actuator (102; 302; 502) for deploying the sheath by interaction with a sheath deployment mechanism (104; 304; 504); the sheath being configured to be stationary in relation to the needle until a syringe plunger (116; 316; 516) reaches a sheath release point on its inward stroke, and the sheath actuator being configured for deployment of the sheath on movement of the sheath actuator relative to the syringe plunger after the sheath release point.
Claims23
An apparatus for use with a syringe for providing a safety syringe, the apparatus comprising:
- a sheath deployable for at least partially covering a needle of the syringe;
- and
- a sheath actuator for deploying the sheath by interaction with a sheath deployment mechanism,
- wherein the sheath deployment mechanism comprises a rotatable linkage comprising a first thread configured to translate rotation of the linkage into linear motion of the sheath for deployment thereof,
- wherein the sheath is configured to be stationary in relation to the needle until a syringe plunger reaches a sheath release point on its inward stroke, and
- wherein the sheath actuator is configured for deployment of the sheath on movement of the sheath actuator relative to the syringe plunger after the sheath release point.
