Fluid transfer connector
A fluid transfer connector or adapter for coupling to a container or pharmacy bottle for facilitating the transfer of fluid or medicine from the bottle to a syringe, or from the syringe to the bottle. Optionally, an additional connector can be provided for coupling the fluid transfer connector to the syringe.
1. A bottle adapter connector comprising:
a cylindrical body comprising an outer peripheral surface having an outer diameter D 1 at an upper end and a lower end of the body and a length H extending from the upper end to the lower end of the body, the outer peripheral surface defining a plurality of outer peripheral steps laterally offset from each other extending along the entire length H, and an inner peripheral surface;
a recess defined by the inner peripheral surface of the body, a base member, and a male coupling centrally positioned on the base member, the male coupling comprising a conduit extending therethrough;
wherein the bottle adapter connector is configured to engage a bottle opening having an interior diameter of up to 5 millimeters difference with respect to the diameter D 1 of the body.
2. The bottle adapter connector of claim 1 , wherein the male coupling comprises a male ISO 80369-3 compatible coupling.
3. The bottle adapter of claim 2 , wherein the male ISO 80369-3 compatible coupling is configured for engagement with a female ISO 80369-3 compatible coupling.
4. The bottle adapter connector of claim 1 , wherein the conduit comprises a cylindrical shape along the length H.
5. The bottle adapter connector of claim 1 , wherein the plurality of outer peripheral steps are resilient and flexible, further wherein the outer peripheral surface comprises a bellows shape formed by the plurality of outer peripheral steps.
6. The bottle adapter connector of claim 5 , wherein the diameter D 1 is in a range between about 12-28 millimeters.
7. The bottle adapter of claim 1 , further comprising a cap tethered to the body of the bottle adapter.
8. The bottle adapter of claim 1 , wherein the base member is substantially flexible and elastically deformable such that the male coupling is movable in an axial direction.
9. The bottle adapter of claim 8 , wherein the male coupling extends beyond an end of the body such that closure of a cap atop the connector causes axial displacement of the male coupling, and wherein the conduit is generally sealed with the cap.
