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. Optionally, the connector can be provided with a sloped base for preventing residual amounts of fluids from remaining within the bottle.
1. A bottle adapter connector comprising:
a cylindrical body extending between a first end and a second end, and comprising an outer peripheral surface and an inner peripheral surface; and
a recess defined by the inner peripheral surface of the body, a base portion positioned at the second end of the cylindrical body, and a male coupling centrally positioned on the base portion and projecting towards the first end, the male coupling comprising a conduit extending therethrough,
wherein the base portion comprises a sloped surface extending towards the first end and up to the conduit of the male coupling, and a tapered-off portion extending from the sloped surface to the outer peripheral surface of the cylindrical body at the second end, wherein the tapered-off portion has a different taper angle than an angle of the sloped surface,
further wherein the recess is accessible from the first end and extends continuously around the male coupling from the sloped surface of the base portion to the first end,
wherein the outer peripheral surface comprises at least one flange for providing frictional engagement with an opening or mouth of a medicine bottle, wherein an uppermost flange is offset a distance of between about 0.1-0.75 millimeters from the second end of the cylindrical 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 connector 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 at least one flange comprises a plurality of laterally offset flanges.
5. The bottle adapter connector of claim 4 , wherein the cylindrical body of the bottle adapter connector comprises a diameter of between about 12-28 millimeters.
6. The bottle adapter connector of claim 1 , further comprising a shelf extending outwardly from the outer peripheral surface of the cylindrical body.
7. The bottle adapter connector of claim 1 , wherein the sloped surface is angled between about 0.5-89.5 degrees relative to the extension of the cylindrical body.
8. The bottle adapter connector of claim 1 , wherein the sloped surface is angled between about 30-70 degrees relative to the extension of the cylindrical body.
9. The bottle adapter connector of claim 6 , wherein a surface of the shelf is configured for engagement with an end portion of a mouth of a bottle when the connector is fully inserted within the mouth of the bottle.
10. The bottle adapter connector of claim 1 , further comprising a lead-in portion defined at the second end.
11. The bottle adapter connector of claim 1 , wherein the male coupling extends beyond an end of the body such that closure of a cap atop the connector causes the conduit of the male coupling to be sealed with the cap.
12. The bottle adapter connector of claim 1 , wherein at least a portion of the sloped surface comprises a texturized surface.
13. The bottle adapter connector of claim 12 , wherein the texturized surface comprises a hydrophobic or oleophobic surface.
14. A bottle adapter connector for connecting with an opening or mouth of a bottle and for withdrawing fluids from the bottle and within a syringe connected to the bottle adapter connector, the connector comprising:
a cylindrical body comprising an outer peripheral surface and an inner peripheral surface; and
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 base member comprises a sloped surface that is sloped inwardly towards the conduit such that a substantial amount, if not all, of the fluid within the bottle, is directed to flow within the conduit and further into the syringe when it is desired to withdraw fluids from the bottle, and the base member further comprises a tapered-off portion extending from the sloped surface to the outer peripheral surface of the cylindrical body at the second end, wherein the tapered-off portion has a different taper angle than an angle of the sloped surface; and
wherein the recess extends continuously around the sloped surface and the male coupling,
wherein the outer peripheral surface comprises at least one flange for providing frictional engagement with an opening or mouth of a medicine bottle, wherein an uppermost flange is offset a distance of between about 0.1-0.75 millimeters from the second end of the cylindrical body.
15. The bottle adapter connector of claim 14 , wherein the sloped surface is angled between about 30-70 degrees relative to the cylindrical body.
16. The bottle adapter connector of claim 14 , wherein the male coupling comprises a male ISO 80369-3 compatible coupling.
17. The bottle adapter connector of claim 16 , wherein the male ISO 80369-3 compatible coupling is configured for engagement with a female ISO 80369-3 compatible coupling.
18. The bottle adapter connector of claim 14 , wherein at least a portion of the sloped surface comprises a texturized, hydrophobic or oleophobic surface.
19. The bottle adapter connector of claim 1 , wherein the inner peripheral surface of the cylindrical body extends continuously around the recess from the base portion to the first end.
20. The bottle adapter connector of claim 14 , wherein the inner peripheral surface of the cylindrical body extends continuously around the recess from the base portion to the first end.
