Needle shielding systems (500 600) are disclosed. The needle shielding system (600) comprises a needle (300) a cover sleeve (100 200) and a needle shield (400). The needle (300) has a needle tip (304) and a needle bulge (308) spaced apart from the needle tip (304). The cover sleeve (100 200) is slidably mounted over the needle (300) and comprises an end portion (104 204) having an internal diameter smaller than the width of the needle bulge (308) and a cover sleeve shaft (112 212) extending from the end portion (104 204) towards the needle tip (304) and having an internal diameter larger than the width of the needle bulge (308). The needle shield (400) comprises a base plate (404) slidably mounted over the needle (300) adjacent to the end portion (104 204) and at least one resilient arm (416) extending from the base plate (404) towards the needle tip (304). In use the needle shield (400) and cover sleeve (100 200) move along the needle (300) until the end portion (104 204) contacts the needle bulge (308) and the cover sleeve shaft (112 212) and the arm (416) cover the needle tip (304).
