Abstract: Some embodiments are directed toward a safety needle assembly including a hub having a proximal end for connecting with a syringe extending in a proximal area of the hub; a needle longitudinally extending from a distal end of the hub in a distal area of the hub; and a sheath pivotally connected to the hub. The sheath can have two side walls connected by a back wall defining a receiving space therebetween for receiving the needle; wherein the sheath is adjustable between a starting position in which the sheath is substantially positioned in the distal area of the hub, between a use position in which the sheath is substantially positioned in the proximal area of the hub, and between a locked position in which the sheath is locked to secure the needle into the receiving space.

Abstract: Some embodiments are directed to a needle assembly that includes a needle having a textured portion and non-textured portion adjacent to the textured portion, and a hub arranged over at least a part of the textured portion of the needle.
The textured portion includes laser etched grooves formed on an outer surface of the needle and oriented in a circumferential direction of the needle. Each of the laser etched grooves has two protruded portions and a dented portion interposed between the two protruded portions.
Each of the two protruded portions has a top surface located above an outer surface of non-textured portion, and the dented portion has a bottom surface located below the outer surface of non-textured portion.
