Multifunctional Medical Access Device
First Claim
1. A medical access device, comprising:
- a syringe needle having a proximal end and a distal end configured for percutaneous use; and
a safety shield supportable on the syringe needle, the safety shield including;
a pair of spaced legs each having a distal segment and a proximal segment, each of the proximal segments having a proximal end fixed with respect to the syringe needle and a distal end hingedly attached to the distal segment at a hinge member, each proximal segment including a camming surface;
a nose member connected to a distal end of each distal segment of the pair of spaced legs, wherein the nose member is translatably disposed on the syringe needle, wherein the nose member defines a blunt tip; and
a trigger having a camming member and being movable to move the camming member into engagement with the camming surfaces of the proximal segments to effect movement of the legs between;
a first position in which the nose member and the distal ends of the distal segments shield at least a distal end of the syringe needle; and
a second position in which the distal end of the syringe needle is shielded by the nose member and capable of being at least partially exposed from a distal end of the nose member when the nose member is moved in a proximal direction relative to the syringe needle.

Abstract
A medical access device is provided including a syringe needle and a safety shield supportable on the syringe needle. The safety shield includes a pair of spaced legs each having a distal segment and a proximal segment, each of the proximal segments having a proximal end fixed with respect to the syringe needle and a distal end hingedly attached to the distal segment at a hinge member, each proximal segment including a camming surface. The safety shield also includes a nose member connected to a distal end of each distal segment of the pair of spaced legs. The safety shield also includes a trigger being movable to move the camming member into engagement with the camming surfaces of the proximal segments to effect movement of the legs between a first position and a second position.

22. A medical access device, comprising:
-
a syringe needle having a proximal end and a distal end, the syringe needle slidably extending through at least a body portion of a nose member defining a blunt tip and defining a longitudinal axis therethrough; a pair of spaced legs each having a distal segment and a proximal segment, the distal segments cooperating with the proximal segments via hinge members, the legs adapted to act as a safety shield pivotally connected to the syringe needle via at least one retention member; and a trigger mechanism supported on a needle hub or the retention member, the trigger mechanism having a lever and a camming member, the trigger mechanism configured to move the camming member into engagement with camming surfaces of the proximal segments of the legs to effect movement of the legs between a first position and a second position, the movement of the legs being perpendicular to the longitudinal axis defined by the syringe needle. - View Dependent Claims (23, 24, 25, 26, 27)
