A hypodermic needle extraction device for removing a hypodermic needle from a syringe having a syringe body and a luer, the device including at least one guide rod disposed with the device, a carriage assembly having a carriage slidably mounted on the guide rod, and a needle extraction assembly configured to grasp the needle such that the needle is separated from the syringe body as the syringe body and needle are urged apart. This Abstract is presented to meet requirements of 37 C.F.R. §1.72(b) only. This Abstract is not intended to identify key elements of the apparatus and methods disclosed herein or to delineate the scope thereof.

1. An apparatus, comprising: a gripper adapted to grasp a needle;a syringe holder to secure a luer inserted into the syringe holder by a user, the luer engaged with a syringe body and the needle engaged with the luer, the syringe holder formed as a cylindrical structure with a static wall, the syringe holder positions the needle for grasping by the gripper; and,wherein with the needle grasped by the gripper the syringe holder and the gripper are adapted to move apart from one another linearly in a direction defined by a length of the needle without relative rotation between the needle and the luer to withdraw the needle entirely from the luer. 2. The apparatus as in claim 1, wherein the luer is generally at ambient temperature as the needle is withdrawn therefrom. 3. The apparatus as in claim 1, further comprising: a heater element to apply heat to the luer to soften the luer in order to facilitate withdrawal of the needle from the luer. 4. The apparatus as in claim 3, wherein the heater element is heated to a temperature of about 130° C. 5. The apparatus as in claim 1, further comprising: a sensor adapted to detect insertion of the luer into the syringe holder. 6. The apparatus as in claim 1, wherein the syringe holder is fixed and the gripper is movable to move linearly apart from the syringe holder. 7. The apparatus as in claim 1, wherein the gripper comprises: a gripper motor;a stationary needle gripper;a movable needle gripper operably connect to the gripper motor such that the gripper motor may move the movable needle gripper toward or away from the stationary needle gripper to grip the needle between the stationary needle gripper and the movable needle gripper or release the needle from the stationary needle gripper and movable needle gripper, respectively; anda loop disposed about the movable needle gripper, the loop engages the needle to release the needle from the stationary needle gripper as the movable needle gripper moves away from the stationary needle gripper. 8. The apparatus as in claim 1, further comprising: a housing, the syringe holder and the gripper being disposed about the housing; and,a drawer slidably received within the housing and operative to receive the needle therein following withdrawal of the needle from the luer; and,a bin door disposed about the drawer, the bin door adapted to move from an open position to a locked closed position as the drawer is removed from the housing. 9. A method, comprising the steps of: securing a luer within a syringe holder by inserting the luer into the syringe holder, the luer being engaged with a syringe body and a needle being engaged with the luer, the syringe holder being formed as a cylindrical structure having a static wall, the syringe holder positioning the needle for grasping by a gripper;grasping the needle by the gripper;and,withdrawing the needle entirely from the luer by moving the syringe holder and the gripper assembly linearly apart from one another generally in a direction defined by a length of the needle without relative rotation between the needle and the luer following the step of grasping the needle by the gripper assembly. 10. The method as in claim 9, further comprising the step of: softening the luer by heating the luer using a heater element thereby facilitating the withdrawing of the needle from the luer. 11. The method as in claim 10, wherein the heater element has a temperature of approximately 130° C. 12. The method as in claim 9, further comprising the step of: detecting insertion of the luer into the syringe holder using a sensor thereupon initiating the grasping step and the withdrawing step. 13. The method as in claim 9, wherein the withdrawing step is performed by moving the gripper linearly with the syringe holder being fixed. 14. The method as in claim 9, further comprising the step of: sterilizing the needle following the step of withdrawing the needle from the luer. 15. The method as in claim 9, further comprising the step of: sterilizing the syringe body following the step of withdrawing the needle entirely from the luer. 16. The method as in claim 9, further comprising the steps of: receiving the needle within a drawer following the withdrawing step; and,positioning a bin door disposed about the drawer from an open position to a closed locked position by removing the drawer from a housing with the needle contained therein, the needle having been received within the drawer.
