The TK Safety Needle consists of a hypodermic needle with a hinged safety sheath attached to the needle hub. The safety sheath is simultaneously activated when manually pressed over the needle after use and prior to disposal to minimize the possibility of sharps injury. The safety sheath is activated with one-hand operation by pressing the sheath either with the finger or thumb, or by surface activation. The locking mechanism is positioned within the center and proximal end of the sheath. The hinge feature allows the medical practitioner the flexibility to adjust the sheath to its desired position for use.
A non-dedicated, sharp bevel-edged, hollow tubular device intended to be inserted beneath the skin of a patient while connected to a noninvasive device (e.g., syringe, secondary medication set) to administer and/or withdraw (aspirate) fluids/drugs; it may also be used for fluid/drug preparation. Some types are designed with a shielding mechanism (e.g., safety cap) for protection from sharp injuries. It is not specifically designed for blood collection or artery puncture, and does not have wings for fixation/placement (i.e., not a blood collection, intra-arterial, or venous butterfly needle). This is a single-use device.
