Abstract
Needle shielding systems are disclosed. The needle shielding system comprises a needle, a cover sleeve, and a needle shield. The needle has a needle tip and a needle bulge spaced apart from the needle tip. The cover sleeve is slidably mounted over the needle and comprises an end portion having an internal diameter smaller than the width of the needle bulge, and a cover sleeve shaft extending from the end portion towards the needle tip and having an internal diameter larger than the width of the needle bulge. The needle shield comprises a base plate slidably mounted over the needle adjacent to the end portion, and at least one resilient arm extending from the base plate towards the needle tip. In use the needle shield and cover sleeve move along the needle until the end portion contacts the needle bulge and the cover sleeve shaft and the arm cover the needle tip.
