ABSTRACT:
A system is disclosed for removing disposable needles from syringes, which requires only one hand to operate and which exposes the user to minimal risk of contact with the contaminated needle. The user inserts the syringe and presses downwardly, whereupon disconnecting gears engaging the collar of the needle unscrew the needle and allow it to drop into a container. Return springs then automatically return the device to its original configuration.
