CATHETER PLACEMENT DEVICE

摘要

A deep vein intravenous introducer has a wheel located toward the front end of the device that can be rotated by the index finger of the user. After placement of the needle in the lumen of the vessel, the user rotates the wheel, which turns a drive wheel. The drive wheel has an outer surface that advances the guide wire through the center of the needle and into the patient. Once the guide wire is advanced into the vessel lumen the catheter can be advanced over the guide wire with a hub or finger tab on the catheter close to the index finger. The operation can be performed by one hand without moving the hand from its initial position.
