    • PROBLEM TO BE SOLVED: To provide a highly safe cartridge type syringe needle capable of inhibiting a needle tip accident, etc. SOLUTION: The syringe needle cartridge 1 comprises a needle holder 5 to hold a piercing syringe needle 11 in the axial direction, a latch ring 4 to hold the needle holder 5 with a latch part 42 reamed outward in the radial direction by the elastic deformation, and a housing 10 to hold the latch ring 4 and the needle holder 5. The needle holder 5 can drive the latch ring 4 to advance to a restriction position when the needle holder 5 is advanced to the housing 10 in the axial direction for the injection behavior, and the needle holder is pulled out in the axial direction from the latch ring 4 restricted at the restriction position when the needle holder is retracted in the axial direction to return to the initial position.

    • PROBLEM TO BE SOLVED: To provide a needle safety device capable of obtaining safety about accidental needlestick not to make it difficult that a medical operator looks a cannula between a patient skin and a hub of the needle cannula or the base position near the hub. SOLUTION: A needle assembly 10 includes a needle cannula 22 with an intravenous end and a non-patient end. The cannula 22 is mounted to a needle holder 12 so that the non-patient-end projects into the holder 12. A safety shield 28 is telescoped over the needle cannula 22 and is movable from a proximal position 14 where the intravenous end of the cannula 22 is exposed to a distal position 16 where the intravenous end is shielded. The safety shield 28 is actuated and propelled into the distal position in response to insertion of a blood collection tube into the holder 12. However, a slide back actuator 65 extends from the safety shield 28 to permit the shield to be retracted into a proximal position during use and before the safety shield 28 is locked in the distal position.
