Expandable intra-venous catheter for a faster intra-venous fluid challenge

摘要

An expandable intra-venous catheter for a faster intra-venous fluid challenge combination has a needle with a tip and an opposite base, a block receiving the needle axially, an inflator port in the block and an opposite IV port 5 in the block, the IV port has fluid communication into the needle, at least three inflators deployed along the needle outwardly from the block, the inflator port has gaseous communication into the inflators, a sheath extending from the block over the inflators towards the tip, and an IV tube upon the needle and within the sheath. The catheter has a flat state and an expanded state. The catheter minimizes the need for multiple access points and raises the rate of access success upon a practitioner's initial IV attempt.
