Abstract

A safety Huber angled needle device including a right angled Huber needle and a protective shield. The needle has a distal end portion extending generally perpendicularly its proximal end portion and terminating in a piercing tip. The protective shield includes a central hub and a pair of wing members movably secured to it on opposite sides of the central hub. The central hub has a distal end, a proximal end and a passageway through which the proximal end portion of the needle extends so that the distal end portion of the needle projects out of the passageway perpendicular to the central 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 the piercing tip. The wing members also include plural connectors for cooperation with each other to hold them the closed state.

Claims

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 wing members, said central hub having a longitudinal central axis, a distal end, a proximal end and a passageway extending through said central hub along said horizontal 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 passageway, each of said wing members being a generally planar member, with each wing member mounted to said central hub on opposite sides thereof and being arranged to be moved from an open state, wherein said wing members are generally coplanar with each other, to a closed state, wherein said wing members abut each other with said distal portion of said Huber needle disposed between said wings to enclose said piercing tip, each of said wing members including at least one connector for holding said wing members in said closed state.

2. The device of claim 1 wherein at least one of said wing members includes a channel therein for receipt of said piercing tip when said wing members are in said closed state.

3. The device of claim 2 wherein both of said wing members include a channel therein, said channels conjoining when said wing members are in said closed state to form an enclosed recess for receipt of said piercing tip.

4. The device of claim 3 wherein each channel is generally linear and extends within its associated wing member from a first end point adjacent said central hub to a second end point more remote from said central hub, and wherein one of said channels of one of said wing members includes an arrowhead-shaped recess located at said second end point of said one of said wing members and wherein the other of said channels includes an arrowhead shaped projection located at said second end point of the other of said wing members, said arrowhead shaped projection being arranged to fit within said arrowhead shaped recess when said wing members are in said closed state.

5. The device of claim 1 wherein said at least one connector comprise at least one projection and at least one cooperating bore.

6. The device of claim 5 wherein one of said wing portions includes said at least one projection and wherein the other of said wing members includes said at least one bore.

7. The device of claim 6 wherein said at least one projection comprises post and wherein said at least one bore comprises an aperture whose cross sectional area is approximately equal to that of said post to tightly receive said post therein.

8. The device of claim 7 wherein said aperture includes a flared mouth for facilitating entry of said post into said aperture.

9. The device of claim 8 wherein said device comprises plural apertures and plural cooperating posts.

10. The device of claim 1 wherein said wing members are flexible to bend from said open state to said closed state.

11. The device of claim 1 wherein said shield is formed of a moldable material and wherein said wing members are connected to said central hub on opposite sides thereof by respective living hinges.

12. The device of claim 11 wherein said wings are flexible.

13. The device of claim 1 additionally comprising a flange upstanding from said central hub, said flange extending in the opposite directions than said wing members when said wing members are in said closed state.

14. The device of claim 13 wherein said central hub is of a generally rectangular cross sectional area.

15. The device of claim 1 additionally comprising a tube connected to said proximal end portion of said Huber needle.

17. The shield of claim 16 wherein at least one of said wing members includes a channel therein for receipt of the piercing tip of the Huber needle when said wing members are in said closed state.

18. The shield of claim 17 wherein both of said wing members include a channel therein, said channels conjoining when said wing members are in said closed state to form an enclosed recess for receipt of the piercing tip of the Huber needle.

19. The shield of claim 16 wherein said at least one connector comprise at least one projection and at least one cooperating bore.

20. The shield of claim 19 wherein one of said wing portions includes said at least one projection and wherein the other of said wing members includes said at least one bore.

21. The shield of claim 16 wherein said wing members are flexible to bend from said open state to said closed state.

22. The shield of claim 16 wherein said shield is formed of a moldable material and wherein said wing members are connected to said central hub on opposite sides thereof by respective living hinges.

23. The shield of claim 12 wherein said wings are flexible.

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 a longitudinal central axis, a distal end, a proximal end and a passageway extending through said central hub along said horizontal 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 passageway, each of said wing members being a generally planar member, with each wing member mounted to said central hub on opposite sides thereof and being arranged to be moved from an open state, wherein said wing members are generally coplanar with each other, to a closed state, wherein said wing members abut each other with the distal portion of the Huber needle disposed between said wings to enclose the piercing tip of the Huber needle, each of said wing members including at least one connector for holding said wing members in said closed state.
