Abstract
A transfer device for charging a series of hypodermic syringes with medicament from a vial, such as in hospital pharmacies. The transfer device includes a valved spike with a syringe coupler rigidly supported on the spike. Contained within the syringe coupler is a longitudinally collapsible valve that opens upon insertion of a blunt syringe tip into the coupler and closes upon removal of such syringe tip. A protective skirt on the coupler has snap lugs for securing the transfer device to the vial.
