ABSTRACT:
A hypodermic syringe uncapping device includes a housing enclosing two opposed, pivotal arms adapted to grip a cap protecting a hypodermic syringe needle. Upon insertion through a hole in the housing, the capped needle is forced against a movable plunger whose lower end engages one of a number of pins extending from the surface of a rotatable cam located between the arms. Rotation of the cam thus induced allows the arms to pivot toward each other under the urging of an arm-connecting spring, causing the arms to grasp the cap and thereby allow subsequent withdrawal of the needle. When the needle is reinserted in the cap and the cap is again pushed against the plunger, the cam is rotated still further, forcing the arms apart and permitting the cap to be withdrawn from the device.
