Problems solved by technology

[0007] These prior art safe catheters all exhibit one or more disadvantages: when the needle tip is covered by the safety mechanism, it is possible to expose medical workers or others to blood or body fluids, whether percutaneous or non-percutaneous risks of
This causes the risk of dislodging the distal arm parts 13 and / or 14 from the protected distal needle tip 18.

Embodiment Construction

[0063] Figure 6 to Figure 11 A needle guard 100 is shown according to some embodiments. According to one embodiment, as Figure 6A and 6B As shown, the first portion 110 of the needle guard 100 is made of a resilient flat material and is shaped to present Figure 7-10 In the use configuration, the second part 150 of the needle guard 100 (see Figure 11 and Figure 12 ) defines an elongated member 152 having a passageway 153 therethrough extending between a proximal end 154 and a distal end 156 . Figure 7 and Figure 8 A different side view is shown of the needle guard 100 in a first axial position on an injection needle 130 whose distal end 134 is unprotected. Figure 9 and Figure 10 A different side view of the guard 100 is shown in a second axial position on the needle 130, the distal end 134 including the entire bevel 136 being protected.

[0064] In one embodiment, the first portion 110 of the needle guard 100 has a first resilient arm 101 and a second resilient...

Abstract

A needle guard assembly having a resilient arm extending from a base situated to slide along the shaft of a needle. In one implementation the needle guard has an elongate containment member that rideswith the resilient arm and is co-operable with the resilient arm to effectuate a covering of the entire distal tip of the needle upon the needle being retracted into the needle guard.
