Abstract
A method for accessing a blood vessel using a catheter insertion device. The catheter insertion device includes a housing, a needle, a catheter, a guidewire, and a thumbwheel. The thumbwheel is rotatably fastened at a front end of the housing and accessible through an opening in the housing. The guidewire is coupled to the thumbwheel such that an axis of rotation of the thumbwheel is perpendicular to the guidewire and rotation of the thumbwheel advances the guidewire through the lumen of the needle. The method includes preparing the catheter insertion device, inserting a tip of the needle and distal end of the catheter into a blood vessel, advancing the guidewire out of the lumen of the needle into the blood vessel by holding the housing and rotating the thumbwheel, furthering the distal end of the catheter over the guidewire, and removing the needle and the guidewire from the catheter.
