Abstract

A sterile tube connector for a fluid circuit system comprising a housing. A first opening is configured to receive a first length of tubing in communication with a first chamber. A second opening is configured for communicating with the first chamber when the tube connector is in an open configuration but not in a closed configuration. The second opening is configured to reversibly engage a third opening to form a second chamber. The third opening is configured for communicating with a second length of tubing. A first portion of the housing forming the first opening comprises a material at least partially permeable to a sterilization energy source for sterilizing contents of the second chamber.

First claim

The invention claimed is:

1. A tube connector for a fluid circuit system moveable between a closed configuration and an open configuration comprising: a housing comprising: a first sub-housing having a first opening configured to receive a first length of tubing in communication with a first chamber and a second opening configured for communicating with the first chamber when the tube connector is in the open configuration but not in the closed configuration; a second sub-housing having a third opening configured to receive a second length of tubing in communication with a second chamber and a fourth opening configured for communicating with the second chamber when the tube connector is in the open configuration but not in the closed configuration; each of the first and second sub-housings having a connector segment and a socket segment configured to directly secure one of the respective lengths of tubing thereto, with the socket segment being movable relative to the connector segment for the first sub-housing to move the tube connector between the closed and open configurations, and the socket segment being immovably fixed to the connector segment for the second sub-housing, wherein the second opening and the fourth opening are configured to engage each other to form a third chamber that communicates with the first chamber and the second chamber when the tube connector is in the open configuration but not when in the closed configuration.

2. The tube connector of claim 1 , wherein at least a portion of the first and/or second sub-housings comprises a material comprising at least one of cyclic olefin copolymer (COC), poly(methyl methacrylate), polymethylpentene, and quartz glass.

3. The tube connector of claim 1 , wherein the tube connector is configured to shift from a closed configuration to an open configuration when the second or fourth opening is translationally shifted relative to the first or third opening.

4. The tube connector of claim 1 , wherein the tube connector is configured to shift from a closed configuration to an open configuration when the first and/or second chamber is translationally shifted relative to the third chamber.

5. The tube connector of claim 1 , wherein the second opening and the fourth opening are configured to engage each other in at least one of a friction fit, an interference fit, a Luer fit, and a threaded fit to form the third chamber.

6. A sterile tube connector for a fluid circuit system moveable between a closed configuration and an open configuration comprising a housing comprising: a first sub-housing having a first opening configured to receive a first length of tubing in communication with a first chamber and a second opening configured for communicating with the first chamber when the tube connector is in the open configuration but not in the closed configuration; a second sub-housing having a third opening configured to receive a second length of tubing in communication with a second chamber; wherein the second opening is configured to reversibly engage the third opening to form a second chamber; each of the first and second sub-housings having a connector segment and a socket segment configured to directly secure one of the respective lengths of tubing thereto, with the socket segment being movable relative to the connector segment for the first sub-housing to move the tube connector between the closed and open configurations and the socket segment being immovably fixed to the connector segment for the second sub-housing, wherein a first portion of the housing forming the first opening comprises a material at least partially permeable to a sterilization energy source for sterilizing contents of the second chamber.

7. The sterile tube connector of claim 6 , wherein a second portion of the housing forming the first opening comprises a material less permeable to the sterilization energy source.

8. The sterile tube connector of claim 6 , wherein the material comprises at least one of cyclic olefin copolymer, poly(methyl methacrylate), polymethylpentene, and quartz glass, and the sterilization energy source comprises UV-C light.

9. The sterile tube connector of claim 7 , wherein the material of the second portion comprises polyurethane and/or silica aerogel and the sterilization energy source comprises at least one of heat, steam, electron beam, and gamma rays.

10. The sterile tube connector of claim 6 , wherein the tube connector is configured to shift from the closed configuration to the open configuration when a linear force is applied to the tube connector in a direction parallel to the first length of tubing.

11. The tube connector of claim 1 wherein the socket segment of one of the first and second sub-housings has a stopper associated therewith for selective engagement with a valve associated with the connector segment of its respective sub-housing, the stopper being mounted to a compressible member and having a tapered side wall, and the valve comprising a surface defining an aperture, the tapered side wall of the stopper being spaced from the surface defining the aperture to permit flow through the valve when in the open configuration and to engage the surface defining the aperture to prevent flow through the valve when in the closed configuration.

12. The sterile tube connector of claim 6 wherein the socket segment of one of the first and second sub-housings has a stopper associated therewith for selective engagement with a valve associated with the connector segment of its respective sub-housing, the stopper being mounted to a compressible member and having a tapered side wall, and the valve comprising a surface defining an aperture, the tapered side wall of the stopper being spaced from the surface defining the aperture to permit flow through the valve when in the open configuration and to engage the surface defining the aperture to prevent flow through the valve when in the closed configuration.
