Safety angled indwelling needle and a protective shield for a safety angled indwelling needle
First Claim
1. A safety Huber angled needle device, said device comprising a Huber needle and a protective shield, said Huber needle comprising a hollow member having a distal end portion and a proximal end portion, said distal end portion extending at an angle to said proximal end portion and terminating in a piercing tip, said protective shield comprising a central hub and a pair of first and second wing members, said central hub having diametrically opposed sides, a longitudinal central axis, a distal end, a proximal end and a passageway extending through said central hub along said longitudinal central axis, said proximal end portion of said Huber needle extending through said passageway so that said distal end portion of said Huber needle extends out of said passageway and at an angle to said longitudinal central axis, said first and second wing members each being a generally planar member having an inner surface, a free end and a fixed end, said fixed end of said first wing member being connected to said central hub at one of said sides, said fixed end of said second wing member being connected to said central hub at the other of said sides, whereupon said first and second wing members are connected to said central hub diametrically opposed from each other, each of said first and second wing members being arranged to be moved from an open state, wherein said first and second wing members are generally coplanar with each other, to a closed state, wherein said inner surfaces of said first and second wing members contiguous with their free ends abut each other with said distal portion of said Huber needle disposed between said inner surfaces of said first and second wing members to enclose said piercing tip, said inner surface of each of said first and second wing members including at least one connector, said at least one connector of said first wing member being arranged for engagement with said at least one connector of said second wing member for holding said first and second wing members in said closed state.

Abstract
A safety needle device including a right angled Huber needle and a protective shield. The protective shield includes a central hub having a passageway and a pair of wing members. The distal end of the needle projects out of the passageway perpendicular to the hub. Each of the wing members is a generally planar member mounted to the central hub so that each can be flexed from an open state, wherein they are generally coplanar with each other, to a closed state, wherein they abut each other with the distal portion of the needle disposed between them to enclose it. The wing members also include plural connectors for cooperation with each other to hold the wing members in the closed state.

- 1. A safety Huber angled needle device, said device comprising a Huber needle and a protective shield, said Huber needle comprising a hollow member having a distal end portion and a proximal end portion, said distal end portion extending at an angle to said proximal end portion and terminating in a piercing tip, said protective shield comprising a central hub and a pair of first and second wing members, said central hub having diametrically opposed sides, a longitudinal central axis, a distal end, a proximal end and a passageway extending through said central hub along said longitudinal central axis, said proximal end portion of said Huber needle extending through said passageway so that said distal end portion of said Huber needle extends out of said passageway and at an angle to said longitudinal central axis, said first and second wing members each being a generally planar member having an inner surface, a free end and a fixed end, said fixed end of said first wing member being connected to said central hub at one of said sides, said fixed end of said second wing member being connected to said central hub at the other of said sides, whereupon said first and second wing members are connected to said central hub diametrically opposed from each other, each of said first and second wing members being arranged to be moved from an open state, wherein said first and second wing members are generally coplanar with each other, to a closed state, wherein said inner surfaces of said first and second wing members contiguous with their free ends abut each other with said distal portion of said Huber needle disposed between said inner surfaces of said first and second wing members to enclose said piercing tip, said inner surface of each of said first and second wing members including at least one connector, said at least one connector of said first wing member being arranged for engagement with said at least one connector of said second wing member for holding said first and second wing members in said closed state.
- 16. A protective shield for a Huber angled needle, said Huber needle comprising a hollow member having a distal end portion and a proximal end portion, the distal end portion extending at an angle to the proximal end portion and terminating in a piercing tip, said protective shield comprising a central hub and a pair of wing members, said central hub having diametrically opposed sides, a longitudinal central axis, a distal end, a proximal end and a passageway extending through said central hub along said longitudinal central axis, said passageway being adapted to receive the proximal end portion of the Huber needle extending through it so that the distal end portion of the Huber needle extends out of said passageway and at an angle to said longitudinal central axis, each of said wing members being a generally planar member having an inner surface, a free end and a fixed end, said fixed end of said first wing member being connected to said central hub at one of said sides, said fixed end of said second wing member being connected to said central hub at the other of said sides, whereupon said first and second wing members are connected to said central hub diametrically opposed from each other, each of said first and second wing members being arranged to be moved from an open state, wherein said first and second wing members are generally coplanar with each other, to a closed state, wherein said inner surfaces of said first and second wing members abut each other with the distal portion of the Huber needle disposed between said inner surfaces of said first and second wing members to enclose the piercing tip of the Huber needle, said inner surface of each of said first and second wing members including at least one connector, said at least one connector of said first wing member being arranged for engagement with said at least one connector of said second wing member for holding said first and second wing members in said closed state.
