Abstract
An ampule having flexible walls with a zone which is programmed to promulgate collapse. The ampule includes an opening that is adapted to dock with a fluid receiving device such as a syringe in air tight sealing engagement. The collapse of the ampule is engineered to occur before breaking the seal that exists between the opening of the ampule and the docking syringe luer tip to ensure sterile transfer of fluid without contamination, especially from ambient air.
Claims17
An ampule having a body with means to promulgate said body's collapse defined by said body being formed as a polygon when said body is taken in section transverse to a long axis, and having two acute angles between sides thereof to cause the collapse, and a cap connected to said body and an opening at a scoreline between said body and said cap.
An ampule having a body with means to promulgate said body's collapse defined by said body being formed as a polygon when said body is taken in section transverse to a long axis, and having two acute angles between sides thereof to cause the collapse, and a cap connected to said body and an opening at a scoreline between said body and said cap wherein said opening has a cross-sectional area dimensioned to overlie an outlet on a dosing device and wherein said opening remains substantially fixed in shape when said body collapses upon fluid extraction.
An ampule having a flexible collapsible body and further provided with means to promulgate said body's collapse in a certain area of said body defined by said body being formed as a polygon when said body is taken in section transverse to a long axis, and having two acute angles between sides thereof to cause the collapse, and a cap connected to said body and an opening at a scoreline between said body and said cap.
