Patent ID: 8647313

Claim:
A safety IV catheter comprising: a) a needle having a needle shaft and a needle tip; b) said needle shaft comprising a bulge; c) a hollow tubular catheter having a proximal end; d) said hollow tubular catheter is secured to the distal end of a catheter hub; e) said catheter hub having a hub section, wherein a chamber is formed in said hub section, and having an inner wall comprising a groove or bump being formed in said inner wall; f) a resilient spring clip needle guard located within said chamber being formed in said hub section of said catheter hub and comprising two curved protrusions or curved sections and two distal end walls; g) said needle being received within said hollow tubular catheter when in a ready position, wherein said needle extends through said chamber, a passageway of said tubular catheter, and distally beyond said catheter hub and said hollow tubular catheter so that said needle tip extends beyond the tapered distal end of said hollow tubular catheter and said needle guard located within said hub chamber is adapted to automatically snap or pivot into a retracted position for blocking access to said distal needle tip and preventing further movement of said needle tip when said needle is in its retracted position; h) said needle guard being urged outwardly such that said two curved sections or curved protrusions contact with said groove or bump of said inner wall of said catheter hub so that the needle guard is retained therein in the ready position; i) said needle guard further comprising a proximal wall or proximal vertical arm having an opening adapted to let said shaft of needle freely pass through and axially move; and j) wherein said bulge on said needle has a diameter greater than that of said opening of said proximal wall or proximal vertical arm so as to engage said opening during proximal movement of said needle.
