ABSTRACT:
A holder for holding a hypodermic syringe sheath includes an operative portion having an upwardly facing surface and a downwardly facing surface and a hole with an upper end in open communication with the upwardly facing surface and a lower end in open communication with the downwardly facing surface. The hole has a lateral size to receive therein a hypodermic syringe sheath of a predetermined size and to hold the sheath in a releasable sliding fit engagement. A method is provided for withdrawing a syringe from press fit engagement with its sheath while leaving the sheath assembled with the holder. The method includes the steps of cocking the axis of the sheath in any direction to bring an outer surface of the sheath into engagement with the wall of the hole at a location at the upwardly facing surface and at a location at the downwardly facing surface, the two locations being diametrically opposite each other, to establish a frictional drag engagement which is stronger than the press fit engagement between the sheath and the syringe, and thereupon pulling the syringe out of engagement with the sheath.
