摘要：
A method for treating a patient using a catheter insertion device. The catheter insertion device includes a housing, a needle, a catheter, a guidewire, and a thumbwheel. The needle extends through the catheter such that a distal end of the needle extends distal of a distal end of the catheter. The guidewire is coupled to the thumbwheel such that rotation of the thumbwheel advances a distal end of the guidewire through a lumen of the needle. The method includes holding the catheter insertion device, inserting the distal end of the needle and catheter into a blood vessel, rotating the thumbwheel to advance the distal end of the guidewire out of the lumen of the needle into the blood vessel, moving the catheter over the guidewire in the blood vessel, and removing the needle and the guidewire from the catheter.
