Abstract

H:\dxl\lntrovn\NRPortbl\DCC\DXL\6834856_I.docx-30/09/2014 A safety catheter assembly comprising a needle hub with a needle attached thereto, said needle comprising a change in profile located proximally of a needle tip, a needle shaft having a side, and a needle diameter; a catheter hub with an interior cavity having a catheter tube attached thereto and having said needle projecting through the catheter hub and the catheter tube such that the needle tip extends beyond a distal end of the catheter tube; a needle guard disposed, at least in part, inside the interior cavity of the catheter hub, said needle guard comprising: a non-metallic base portion comprising a wall having a bore, a proximally facing surface, and a distally facing surface; a first arm including a first free end and a second arm including a second free end extending generally axially from the base portion in a distal direction and having a tensioning member mounted on an exterior thereof, the first free end extending beyond the second free end and including an angled end section extending towards the second arm and contacting a side of the needle shaft; wherein the angled end section comprises a length and a width defining, at least in part, a tip holding space to retain the needle tip within the tip holding space in a protective position as the needle guard pivots or turns on the needle; and wherein the width of the angled end section is larger than a width of the second free end and at least two times larger than a diameter of the needle to confine the needle tip within the needle tip holding space.
