- #$%^&*AU2016208346B220170831.pdf#####Abstract A passive safety needle device is disclosed having a housing, a needle hub, a needle cannula, a retractable sheath, a spring to bias the retractable sheath in a distal direction to cover the distal end of the needle cannula, a radial protrusion to cause the spring to move from the proximal spring position to the distal spring position, and a catch to secure the distal end of the spring to the distal end of the housing. The spring may bias the retractable sheath in a distal direction to cover the distal end of the needle cannula. The radial protrusion causes the spring to move from a proximal spring position to the distal spring position towards the catch located at the distal end of the housing.3/8 A "A AA _ A> A, A A -~ A ~ ~~" , A A I A A -> A A ~" A A A A A .AA A A A~ A A A "A.AAAA A A A A AA A "A A" A A A A A A A A A>A A A A A A 6 A A A A A,AAA A AAAAAAA I A A A~A~ .<A A (1 AA,AAAAA A" A AA~ AA,AA~ AAAAAAAAAAAA5AAA AA,i4 AAAA6~AAAA"A A,> AAAA-AAA5 A"A~ < <~A~A A A A >f~ ~ AAAA AAA7 AA A A~AA~AA"A" A" AA.A AAA,«A AAAA4AAAA.
