Sterile port connection
View Patent ↗Embodiments of the present disclosure are directed to connection assemblies providing a connection between a tubing and a port. The port can be disposed within and particularly extending through a bore of the port. The port and tube are coupled to provide an aseptic connection.
1. An assembly comprising:
a. a port comprising a bore defining a passageway, and one or more engagement elements disposed about an outer periphery of the port;
b. a tube disposed through the bore; and
c. an overmolded element coupling the tube to the port;
d. wherein the bore is non-fluid facing, wherein the one or more engagement elements comprises a barb.
2. The assembly of claim 1 , wherein the port further includes one or more engagement elements disposed about an outer periphery of the port; the tube is composed of a silicone based material; and the overmolded element is composed of a silicone based material; and wherein the assembly further comprises a retention element disposed about and retaining the overmolded element about the port.
3. The assembly of claim 2 , wherein the compressive element applies a compressive force to squeeze the overmolded element or second tube about at least one of the one or more engagement elements.
4. The assembly of claim 1 , wherein the port further includes one or more engagement elements disposed about an outer periphery of the port; the tube is composed of a thermoplastic based material; and the overmolded element is composed of a thermoplastic based material; wherein the overmolded element is covalently bonded to the tube.
5. The assembly of claim 1 , wherein the port is composed of a thermoplastic based material.
6. The assembly of claim 1 , wherein the port is composed of a polypropylene (PP) based material, a polyethylene based material, a fluoropolymer based material, a polyamide based material, or any combination thereof.
7. The assembly of claim 1 , wherein the overmolded element is composed of a thermoplastic based material.
8. The assembly of claim 1 , wherein the overmolded element is composed of a silicone based material.
9. The assembly of claim 1 , wherein the overmolded element is composed of a polypropylene based material, a polyvinyl based material, a thermoplastic elastomeric based material, or any combination thereof.
10. The assembly of claim 1 , wherein the tube is composed of a thermoplastic based material.
11. The assembly of claim 1 , wherein the tube is composed of a silicone based material.
12. The assembly of claim 1 , wherein the outside diameter of the tube is generally the same as or less than the inner diameter of the bore.
13. The assembly of claim 1 , wherein the assembly further comprises a fitting disposed on the end of the tube.
14. An assembly comprising:
a. a port comprising a bore defining a passageway, and one or more engagement elements disposed about an outer periphery of the port;
b. a first tube disposed through the bore; and
c. a second tube disposed over the first tube and disposed over the port;
d. an overmolded element coupling the first tube to the second tube; and
e. a compressive element disposed over the second tube and the port, wherein the one or more engagement elements comprises a barb.
15. An assembly comprising:
a. a vessel having an interior cavity;
b. a port having a bore defining a passageway into the interior cavity of the vessel, and one or more engagement elements disposed about an outer periphery of the port; and
c. a tube;
d. wherein the tube is coupled to the port;
e. wherein the tube extends into the inner cavity of the vessel; and
f. wherein the port is non-fluid facing, wherein the one or more engagement elements comprises a barb, wherein the vessel comprises a flexible bag.
16. The assembly of claim 15 , wherein the vessel comprises at least one flexible wall.
17. The assembly of claim 15 , wherein the vessel comprises an isolation bag.
