Retractable needle shielding device
First Claim
1. A shieldable needle device comprising:
- a hub including a lever extending from an external surface thereof;
a needle cannula extending from said hub, said needle cannula having a puncture tip; and
a housing including a main body portion having a forward opening with said needle cannula extending through said main body portion from said forward opening, and a rearward extension having a longitudinal slot extending axially therealong between a forward slot end and a rearward slot end with said lever of said hub extending through said longitudinal slot and locked at said forward slot end thereof, said housing further including a tip guard within said main body portion;
wherein said lever is radially movable with respect to a longitudinal axis of the needle device to unlock said lever from the forward slot end, and said lever is axially movable toward the rearward slot end causing axial movement of said needle cannula through said forward opening of said housing, thereby retracting said needle cannula within said main body portion of said housing to a position with said tip guard protectively covering said puncture tip of said needle cannula.

Abstract
The present invention is directed to a shieldable needle device. The shieldable needle device includes a hub having a lever extending from an external surface thereof, and a needle cannula with a puncture tip extending from said hub. The hub is interengaged with a housing having a main body portion with the needle cannula extending through a forward opening therein, and a rearward extension with a longitudinal slot extending axially therealong between a forward slot end and a rearward slot end, such that the lever of the hub extends through the longitudinal slot and is locked at the forward slot end thereof. The housing also includes a tip guard within the main body portion which is axially movable along the needle cannula. The lever is radially movable with respect to a longitudinal axis of the needle device to unlock the lever from the forward slot end, and is axially movable toward the rearward slot end to cause axial movement and to thereby retract the needle cannula, with the tip guard protectively covering the puncture tip of the needle cannula.

17. A shieldable needle device comprising:
-
a housing including a main body portion and a rearward extension extending from said main body portion, said main body portion including an internal opening extending therethrough with a locking assembly within said internal opening, said rearward extension including a longitudinal slot extending between a forward slot end adjacent said main body portion and a rearward slot end; a hub including a forward end, a rearward end, and an internal opening extending therethrough, said hub including a lever extending through said longitudinal slot of said housing, said lever including a finger surface extending beyond said longitudinal slot and a locking mechanism for locking said lever at said forward end of said longitudinal slot; and a needle cannula having a forward end extending from said forward end of said hub and into said internal opening of said main body portion of said housing; said lever being radially movable with respect to said longitudinal slot to release said locking mechanism of said lever from a locked position at said forward end of said longitudinal slot, said lever further being axially slidable along said longitudinal slot through said finger surface, thereby causing said needle cannula and said main body portion of said housing to axially move with respect to each other between an extended position in which said forward end of said needle cannula extends from a forward end of said main body portion of said housing and a retracted position in which said forward end of said needle cannula is retracted within said internal opening of said main body portion and said locking assembly engages said forward end of said needle cannula to prevent movement of said needle cannula from said retracted position to said extended position. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A safety blood collection set comprising:
-
a fixture for connecting the blood collection set to a receptacle; a flexible tube having opposed first and second ends, said first end of said flexible tube being connected to said fixture; a hub mounted to said second end of said flexible tube, said hub including a lever extending from an external surface of said hub; a needle cannula extending from said hub, said needle cannula having a puncture tip and an internal lumen in fluid communication with said flexible tube through said hub; and a wingset housing including a main body portion having a forward opening with said needle cannula extending from said forward opening, and a rearward extension having a longitudinal slot extending axially therealong between a forward slot end and a rearward slot end with said lever of said hub extending through said longitudinal slot and locked at said forward slot end, said wingset housing further including a tip guard within said main body portion; wherein radial movement of said lever unlocks said lever from the forward slot end of said longitudinal slot, and axial movement of said lever toward the rearward slot end of said longitudinal slot causes axial movement of said needle cannula through said internal opening of said wingset housing, thereby retracting said needle cannula within said wingset housing to a position with said tip guard protectively covering said puncture tip of said needle cannula. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33)
