Abstract
A vial access device includes a housing having first and second connectors. The first connector is configured to be secured to a first container and the second connector is configured to be secured to a second container. The vial access device further includes a spike member extending from the housing and having a proximal end and a distal end. The spike member defines a vent lumen and a fluid lumen spaced from the vent lumen with each of the vent lumen and the fluid lumen having a distal opening. A shape defined by a circumference of the spike member is only symmetric about one axis at a position between the proximal end of the spike member and the distal opening of the fluid lumen.
Claims21
A vial access device comprising:
- a housing having first and second connectors, the first connector configured to be secured to a first container, the second connector configured to be secured to a second container;
- a spike member extending from the housing and having a proximal end and a distal end, the spike member defining a vent lumen and a fluid lumen spaced from the vent lumen, each of the vent lumen and the fluid lumen having a distal opening, wherein a shape defined by a circumference of the spike member is only symmetric about one axis at a position between the proximal end of the spike member and the distal opening of the fluid lumen, wherein the circumference of the spike member varies in size and shape between the proximal end of the spike member and the distal opening of the fluid lumen.
A vial access device comprising:
- a housing having first and second connectors, the first connector configured to be secured to a first container, the second connector configured to be secured to a second container;
- a spike member extending from the housing and having a proximal end and a distal end, the spike member defining a vent lumen and a fluid lumen spaced from the vent lumen, each of the vent lumen and the fluid lumen having a distal opening, wherein the distal openings of the vent lumen and the fluid lumen are each defined by a top edge and a bottom edge spaced axially from the top edge, wherein the spike member comprises a ring spaced and extending radially outward from the circumference of the spike member, and wherein the ring is configured to rest within a seal of the second container upon insertion of the spike member into the second container.
A drug transfer system comprising:
- a syringe adapter configured to be secured to a first container;
- a vial access device comprising:
- a housing having first and second connectors, the first connector configured to be secured to the syringe adapter, the second connector configured to be secured to a second container;
- a spike member extending from the housing and having a proximal end and a distal end, the spike member defining a vent lumen and a fluid lumen spaced from the vent lumen, each of the vent lumen and the fluid lumen having a distal opening, wherein a shape defined by a circumference of the spike member is only symmetric about one axis at a position between the proximal end of the spike member and the distal opening of the fluid lumen, wherein the circumference of the spike member varies in size and shape between the proximal end of the spike member and the distal opening of the fluid lumen.
