PropertyValue
?:definition
  • Needles designed for the initial percutaneous insertion of a catheter, with means of protection against needlestick injury during and after use. These devices usually include some manually positioned or activated mechanism intended to shield or retract the needle or by some other means decrease the possibility of contact between the needle and the healthcare provider. These needles typically consist of a hollow, blunt, tapered catheter with a sharp obturator inside. Catheter-insertion needles may be used for introduction of drainage catheters into wounds, initial introduction of spinal catheters, initial introduction of peritoneal catheters for dialysis and/or drug infusion, and, most frequently, insertion of percutaneous venous and/or arterial catheters.
