Abstract
Method, system and device involving a needle device with a needle safety element with improved stable structure. A frame can surround the needle safety element to provide added stiffening of the needle safety element. The frame can include stays extending laterally of the needle safety element. The needle safety element with the frame can be slidably located on a needle and in a catheter hub in a ready to use position and be removable from the catheter hub in a protective position.
Claims24
A needle safety assembly comprising:
- a needle safety element slidably mounted on a needle shaft having a needle tip and a radial projection proximal of the needle tip;
- the needle safety element comprising:
- a proximal wall having a perimeter defining an opening;
- a distal wall comprising a surface to block the needle tip in a protective position;
- and
- two movable arms distal of the proximal wall;
- a frame surrounding, at least in part, the needle safety element, said frame comprising:
- a first stay and a second stay connected to a bracket;
- wherein a lug extends from at least one of the stays in a radial direction relative to the needle shaft at a location between the bracket and the proximal wall, wherein said lug comprises a free end opposite an end that attaches to the at least one of the stays.
