Protective cap, for the point of a syringe needle, is covered by a guide sleeve to align the needle with cap opening for insertion without contact with the opening wall to prevent contamination and accidental pricks

摘要

For the insertion of the needle of a syringe (1) into a protective cap (21), there is no contact between the needle point and the cap. A sleeve (31) opens to the exterior with an opening for the insertion of the syringe, matching the syringe dimensions, so that the syringe axis (S) is aligned with the cap axis (C) and the cap opening to pass through without contact with the wall of the opening. The sleeve is of a transparent material, which cannot be penetrated by the needle point by accident.
