First Claim
Patent Images
1. A valved spike transfer device comprising:
- a forwardly extending rigid tubular spike;
a syringe coupler rigidly connected to the spike, said syringe coupler including a valve structure that has a tubular rearwardly projecting syringe tip receiver and a movable sealing means that opens upon insertion of a blunt syringe tip into the syringe tip receiver and closes upon removal of such syringe tip;
a protector skirt projecting rearwardly beyond the tubular syringe tip receiver and spaced radially outward therefrom to define an annular recess of a size to receive a conventional threaded collar surrounding a tapered syringe tip, said tubular syringe tip receiver having a wall sufficiently thin to be received between such conventional tapered adapter and surrounding threaded collar; and
a vial coupling means permanently joined at a fixed location to a unit formed by the syringe coupler and spike.

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.

17. A valved spike transfer device comprising:
- a forwardly extending rigid tubular spike; and
a nozzle coupler rigidly connected to the spike, said nozzle coupler including a valve that has a tubular rearwardly projecting nozzle receiver and a movable sealing means that opens upon insertion of a blunt tubular nozzle into the coupler and closes upon removal of such nozzle from the coupler;
a protector skirt projecting rearwardly beyond the tubular nozzle receiver and spaced radially outward therefrom to define an annular recess of a size to receive a collar approximately the size of a conventional threaded syringe collar, which collar surrounds the nozzle, said tubular nozzle receiver having a wall sufficiently thin to be received between such nozzle and surrounding skirt; and
a vial coupling means permanently joined at a fixed location to a unit formed by the nozzle coupler and spike.

18. A system for transferring dosages of liquid comprising:
- a reservoir medicament vial with a fluid therein;
a valved spike transfer device including a forwardly extending rigid tubular spike with means sealingly connected to such vial, and a nozzle coupler rigidly connected to the spike, said nozzle coupler including a valve structure that has a tubular rearwardly projecting nozzle receiver and a movable sealing member that opens upon insertion of a blunt tubular nozzle into the coupler and closes upon removal of such nozzle;
a protector skirt projecting rearwardly beyond the tubular nozzle receiver and spaced radially outward therefrom to define an annular recess of a size to receive a collar approximately the size of a conventional threaded syringe collar, which collar surrounds the nozzle, said tubular nozzle receiver having a wall sufficiently thin to be received between such nozzle and surrounding skirt; and
