1. A needle-based device comprising:
a body;
a needle protruding from the body for a length thereof;
a needle cap to protect an entirety of the protruding length of the needle in a first state of disuse of the needle-based device by completely encompassing the needle in the first state of disuse of the needle-based device;
a needle shield to encompass the entirety of the protruding length of the needle and at least a partial length of the needle cap in the first state of disuse of the needle-based device, a length of the needle cap protruding outside the needle shield from an end of the needle shield farthest away from the body in the first state of disuse of the needle-based device;
a safety cap to encompass therewithin an entirety of the length of the needle cap protruding outside the needle shield, the safety cap being secured onto an outer surface of the needle shield proximate the end farthest away from the body such that the needle and the needle cap are completely protected and covered during the first state of disuse of the needle-based device; and
guide elements protruding internal to the needle shield from the end of the needle shield farthest away from the body in the first state of disuse of the needle-based device in a direction parallel to a length of the needle shield such that the needle passes through the guide elements to prevent significant lateral movement of the needle and the needle cap in the first state of disuse of the needle-based device,
wherein a distance between the guide elements along a direction perpendicular to the length of the needle shield is less than an inner diameter of the needle shield,
wherein a length of each of the guide elements along the direction of the length of the needle shield is significantly less than the length of the needle shield, and
the body is associated with at least one of; a syringe, a hypodermic needle, a pen injector and a fluid collection device.
