Abstract
A valved medication container for facilitating needleless transfer of medication from the container to a patient. Four embodiments of valve members are disclosed. The first embodiment employs a slidable actuator which is engaged by the nose portion of a syringe and deflected into the container through a slit elastomeric membrane. A second embodiment employs a duckbill which the nose of the syringe biases to an open position. The third embodiment uses axially opposed flapper valves which the nose of the syringe pushes open. The fourth embodiment employs a slidable actuator with a T-shaped passageway which is moved to the open position by the syringe. A vent having a one-way valve for influx of air is provided for larger containers.
Claims20
A valved medication container for use in a needleless medication transfer system including a needleless syringe having a blunt tubular nose end and an injection port in an intravenous tube, said valved medication container comprising:
- a) a container having a neck portion;
- b) a stopper seatable in said neck portion, said stopper including
- i) a longitudinally extending throughbore;
- ii) a valve member positioned within said longitudinally extending throughbore, said valve member including an elastomeric member extending across said throughbore, said elastomeric member having a slit therethrough which has a first closed position and a second open position,
- c) actuator means comprising one of said blunt tubular nose end and an element of said stopper engageable with said slit to move said slit from its first closed position to its second open position permitting medication to be withdrawn from said container for transfer to said injection port.
A valved medication container adapted to permit medication to be withdrawn from said container by a needleless syringe, said valved medication container comprising:
- a) a container having a neck portion;
- b) a stopper seatable in said neck portion, said stopper including
- i) a longitudinally extending throughbore;
- ii) a valve member positioned within said longitudinally extending throughbore, said valve member including an elastomeric member extending across said throughbore, said elastomeric member having an opening therethrough which has a first closed position and a second open position,
- c) actuator means comprising one of said needleless syringe and an element of said stopper engageable with said opening to move said opening from its first closed position to its second open position permitting medication to be withdrawn from said container for transfer to said injection port.
