DETAILED DESCRIPTION OF THE CURRENTLY PREFERRED EMBODIMENTS

(10) In FIG. 1, a connector embodying the present invention is indicated generally by the reference numeral 10. The connector 10 comprises a first or female connector 12 including a first fluid passageway 14 for receiving a fluid therein; a plurality of first ports 16 in fluid communication with the first fluid passageway 14 for passage of the fluid therethrough; and a first deflecting member 18. The first deflecting member 18 includes a first engaging portion 20 radially spaced relative to the first port 16, and a first valve 22 movable between a closed position (FIG. 1) and an open position (FIG. 3) with movement of the first engaging portion 20 between a substantially non-deflected position (FIG. 1) and a fully deflected position (FIG. 3), respectively. In the substantially non-deflected position (FIG. 1), the first valve 22 is located in the closed position forming a fluid-tight seal between the first valve and first ports 16 and preventing the passage of fluid therethrough. In the fully deflected position (FIG. 3), the first valve 22 is located in the fully open position allowing the aseptic passage of fluid through the first ports 16.

(11) The aseptic connector 10 further includes a second or male connector 24 connectable to the first or female connector 12. The second connector 24 includes a second fluid passageway 26 for receiving a fluid therein; a plurality of second ports 28 in fluid communication with the second fluid passageway 26 for the passage of the fluid therethrough; and a second deflecting member 30. The second deflecting member 30 includes a second engaging portion 32 radially spaced relative to the second ports 28, and a second valve 34 movable between a closed position (FIG. 1) and a fully open position (FIG. 3) with movement of the second engaging portion 32 between a substantially non-deflected position (FIG. 1) and a fully deflected position (FIG. 3), respectively. In the substantially non-deflected position (FIG. 1), the second valve 34 is located in the closed position forming a fluid-tight seal between the second valve 34 and second ports 28 and preventing the passage of fluid therethrough. In the fully deflected position (FIG. 3), the second valve 34 is located in the fully open position allowing the passage of fluid through the second ports 28.

(12) As shown in FIGS. 1 through 3, the first and second connectors 12, 24 are movable into engagement with each between non-connected and connected positions. In the non-connected position (FIG. 1), the first and second engaging portions 20, 32 are in the substantially non-deflected positions, and the first and second valves 22, 34 are in the closed positions. In the fully connected position (FIG. 3), the first and second engaging portions 20, 32 are engaged with each other in the fully deflected positions, and the first and second valves 22, 34 are in their fully open positions.

(13) In the non-deflected position (FIG. 1), the first valve 12 forms a fluid-tight seal 36 between the first ports 16 and ambient atmosphere and prevents external contamination of any fluid-contacting surfaces of the first ports 16. The first connector 12 further includes a first body 38 defining a first sealing surface 40 formed adjacent to the first ports 16, and engageable with the first valve 22 in the closed position to form a fluid-tight seal between the first valve and first ports. As can be seen, the first sealing surface 40 is substantially annular, the first valve 22 is substantially annular, and in the closed position, the first valve 22 engages the first sealing surface 40 and forms an annular fluid-tight seal 36 therebetween. The first sealing surface 40 is relatively rigid and the first valve 22 is flexible. In the closed position, the first valve 22 and first sealing surface 40 form an interference fit therebetween at the annular fluid-tight seal 36. As can be seen, the first engaging portion 20 is formed integral with the first valve 22, is radially spaced relative to the first valve 22, extends annularly about the first valve 22, and extends axially relative to the first valve 22. The integral first engaging portion 20 and first valve 22 are made of an elastic material, such as silicone.

(14) In the non-deflected position (FIG. 1), the second valve 24 forms a second fluid-tight seal 42 between the second ports 28 and ambient atmosphere, and prevents external contamination of any fluid-contacting surfaces of the second ports 28. The second connector 24 further includes a second body 44 defining a second sealing surface 46 formed adjacent to the second ports 28, and engageable with the second valve 34 in the closed position to form a fluid-tight seal between the second valve and second ports. As can be seen, the second sealing surface 46 is substantially annular, the second valve 34 is substantially annular, and in the closed position (FIG. 1), the second valve 34 engages the second sealing surface 46 and forms an annular fluid-tight seal 42 therebetween. The second sealing surface 46 is relatively rigid and the second valve 34 is flexible. In the closed position, the second valve 34 and second sealing surface 46 form an interference fit therebetween at the annular fluid-tight seal 42. As can be seen, the second engaging portion 32 is formed integral with the second valve 34, is radially spaced relative to the second valve 34, extends annularly about the second valve 34, and extends axially relative to the second valve 34. The integral second engaging portion 32 and second valve 34 are made of an elastic material, such as silicone.

(15) Each first engaging portion 20, 32 is formed integral with the respective valve 22, 34, is radially spaced relative to the respective valve, extends annularly about the respective valve, and extends axially relative to the respective valve. In the illustrated embodiment, each deflecting portion 20, 32 is substantially dome shaped, and each valve 22, 34 extends laterally with respect to the axis of the respective dome-shaped deflecting portion. Also in the illustrated embodiment, each deflecting portion 20, 32 is substantially cylindrical shaped, and each valve 22, 34 extends substantially normal to an axis of the respective substantially cylindrical-shaped deflecting portion. As indicated above, each engaging portion 20, 32 and integral valve 22, 34 are made of a flexible or elastic material, such as silicone.

(16) It will be understood that the first and second integral valves 22, 34 are formed of any suitable flexible or elastic material. In some embodiments, a suitable elastic material includes silicone, a vulcanized latex and/or a vulcanized rubber. In at least some embodiments, the first and second integral valves 22, 34 are formed of a material having a substantially predetermined creep. Compression set measures the ability of elastomeric materials to maintain elastic properties after prolonged compressive stress and can be used as a measurement of the material's creep property. In some embodiments, the material for the first and second integral valves 22, 34 is selected from materials having a compression set value within the range of about 0% to about 50% (by ASTM D412), and preferably within the range of about 0% to about 25%. In some embodiments, the integral valves 22, 34 form an interference fit with sealing surfaces 40, 46 in the closed position. In the open position, the integral valves 22, 34 are deflected away from sealing surfaces 40, 46. The integral valves 22, 34 are capable of being maintained in either the open or closed positions for substantial periods of time. In some embodiments, the integral valves 22, 34 are maintained in the open position for about 6, 12, 18, 24, 48 or 72 hours, and because of their relatively low creep property, they remain capable of sealingly engaging the sealing surfaces 40, 46 in the closed position thereafter.

(17) As shown in FIGS. 2E and 3, in the fully connected position, the first and second engaging portions 20, 32 engage each other and deflect each other into the deflected positions, and the first and second valves 22, 34 are invaginated within the first and second engaging portions 20, 32 into their fully open positions, the first and second ports 16, 28 are in fluid communication with each other, and as indicated by the broken line arrows in FIG. 3, fluid is permitted to flow through a sterile flow path therebetween that is hermetically sealed with respect to ambient atmosphere. In the fully connected position, the first and second engaging portions 20, 32 form a substantially fluid-tight seal therebetween. The first and second engaging portions 20, 32 extend annularly about the first and second valves 22, 34 and the first and second ports 16, 28, respectively, and form a substantially fluid-tight seal with respect to ambient atmosphere. Also in the fully connected position, the first and second valves 22, 34 extend annularly about the first and second ports 16, 28, respectively, are invaginated or deflected into contact with each other to form a substantially fluid-tight seal therebetween and with respect to ambient atmosphere, and to prevent contamination of any fluid-contacting surfaces of the first and second ports when the valves are in the fully open position. As can be seen, any germs or other contaminants located on or within the deflecting members 18, 30 (i.e., each deflecting member is a deflecting ring of concern), are hermetically sealed within the engaged deflecting members, and thus prevented by the annular, fluid-tight seal between the engaged, opposing valves 22, 34 from contacting any sterile fluid flowing through the connector.

(18) The first or female connector 12 includes a first or female connector housing 48 that extends annularly about the first deflecting member 18 and the first valve 22 and extends axially outwardly therefrom to enclose the respective deflecting member and valve. Similarly, the second or male connector 24 includes a second or male connector housing 50 that extends annularly about the second deflecting member 30 and the second valve 34, and extends axially outwardly therefrom. As shown in FIGS. 2A through 3, the second or male connector housing 50 is receivable within the first or female connector housing 48 to interconnect and place the two connectors in fluid communication with each other. In the connected positions, the second or male connector housing 50 is received within the first or female connector housing 48, and the first and second engaging portions 20, 32 and the first and second valves 22, 34, are located within the second or male connector housing 50. The first body 38 of the first connector 12 defines the first ports 16, and the second body 44 of the second connector 24 defines the second ports 28. As shown in FIGS. 2E and 3, in the fully closed position, a distal portion 52 of the second body 44 is received within a distal portion 54 of the first body 38 to facilitate aligning the first and second connectors and retaining them in the fully closed position. As may be recognized by those of ordinary skill in the pertinent art based on the teachings herein, the first and second connectors 12, 24 can be releasably connected to each other in any of numerous different ways that are currently known, or that later become known, such as by a threaded connection, snap fit, or other releasable interconnection.

(19) In the illustrated embodiment, the first connector 12 includes a plurality of first ports 16 angularly spaced relative to each other, and the second connector 24 includes a plurality of second ports 28 angularly spaced relative to each other. A first fluid conduit 56 is connected in fluid communication with the first fluid passageway 14 of the first connector 12, and a second fluid conduit 58 is connected in fluid communication with the second fluid passageway 26 of the second connector 24. As may be recognized by those of ordinary skill in the pertinent basted on the teachings herein, the ports may take any of numerous different configurations that are currently known, or that later become known. For example, each connector may include only one port, more than one port, and/or one connector may have a different number and/or configuration of ports than the other connector. For example, one connector may have fewer angularly-elongated ports. Similarly, the first and second connectors may or may not be connected to tubes as shown, but rather may be connected to any of numerous different types of fluid sources, receptacles or devices that are currently known, or that later become known.

(20) As shown in FIG. 1, in the non-connected, closed position, each annular fluid-tight seal 36, 42 extends axially between the respective valve 22, 34 and sealing surface 40, 46 to further prevent the ingress of contaminants through the seal. Each sealing surface 40, 46 is relatively rigid, each valve 22, 34 is flexible, and in the closed position, each valve 22, 34 and respective sealing surface 40, 46 form an interference fit therebetween at the respective annular fluid-tight seal 36, 42.

(21) As shown typically in FIG. 3, the first connector includes a first axially and annularly extending base 60 that overlies the first ports 16. A first annular, deflectable joint 62 extends between the first base 60 and first valve 22 to facilitate movement of the first valve 22 between the closed and open positions. The first body 38 defines an annular and axially-extending first base surface 64 that is formed contiguous to the first ports 16, and a first step 66 extending between the base surface 64 and first sealing surface 40. In the illustrated embodiment, the first step 66 is oriented substantially normal the first base surface 64 and first sealing surface 40.

(22) Similar to the first connector 12, and as shown typically in FIG. 3, the second connector 24 includes a second axially and annularly extending base 68 that overlies the second ports 28. A second annular, deflectable joint 70 extends between the second base 68 and second valve 34 to facilitate movement of the second valve 34 between the closed and open positions. The second body 44 defines an annular and axially-extending second base surface 72 that is formed contiguous to the second ports 28 and a second step 74 extending between the base surface 72 and the second sealing surface 46. In the illustrated embodiment, the second step 74 is oriented substantially normal the second base surface 72 and second sealing surface 46.

(23) In the closed position of the first connector 12 (FIG. 1), the first base 60 sealingly engages the first base 64 of the first valve body 38 to form a fluid-tight seal therebetween, the first step 64 is received within, and sealingly engages the first step 66 of the first body 38 to further effectuate a fluid-tight seal, and the first valve 22 sealingly engages the first sealing surface 40 to effectuate the fluid-tight seal between the valve and body. Similarly, in the closed position of the second connector 24, the second base 68 sealingly engages the second base 72 of the second valve body 44 to form a fluid-tight seal therebetween, the second step 70 is received within, and sealingly engages the second step 74 of the second body 44 to further effectuate a fluid-tight seal, and the second valve 34 sealingly engages the second sealing surface 46 to effectuate the fluid-tight seal between the valve and body. As can be seen, in the normally-closed position, all external fluid-contacting surfaces of the first connector body 38 and second connector body 44 are hermetically sealed within the first and second valves 22 and 34, respectively. In the fully connected, open position, on the other hand (FIGS. 2E and 3), the valves 22, 34 are deflected or invaginated into the fully open position into engagement with each other, and thus moved radially away from the respective sealing surfaces 40, 46, the deflecting joints 62, 70 are deflected radially away from the respective steps 64, 72, and the bases 60, 68 are deflected radially away from the respective body base surfaces 64, 72, to thereby define an annulary, axially-extending fluid passageway 76 extending between the two connectors. As indicated by the broken line arrows in FIG. 3, in the connected, fully open position, fluid is permitted to flow from the first fluid passageway 14, through the plurality of ports 16, through the annular, axially-extending passageway 76, through the plurality of second ports 28, and into the second passageway 26. If desired, the fluid may flow in the opposite direction. The annular, axially-extending passageway 76 is hermetically sealed with respect to both the deflectable ring of concern (i.e., the surfaces of the deflecting members 18, 30) and ambient atmosphere by abutting engagement of the first and second valves 22, 34. As can be seen, the fluid passing between the two connectors is maintained sealed with respect to ambient atmosphere, and the surfaces of the connectors that contact such fluid likewise are sealed with respect to ambient atmosphere to thereby maintain the fluid sterile and hermetically sealed with respect to ambient atmosphere.

(24) Turning to FIG. 4A, another embodiment of a connector of the present invention is indicated generally by the reference numeral 110. The connector 110 is substantially the same as the connector 10 described above, and therefore like reference numerals preceded by the numeral “1” are used to indicate like elements. The primary difference of the connector 110 in comparison to connector 10 is that it includes first and second supports 180, 182 located between the bases of the first and second housings 148, 150 and the first and second valves 122, 134, respectively. The first and second supports 180, 182 may be molded with the bases of the first and second integral valves 122, 134, respectively. In some embodiments, the first and second supports are co-molded or overmolded with the first and second integral valves 122, 134. The first and second supports 180, 182 are snap fit into first and second recesses 186, 188, respectively, provided in the bases of the first and second housings 148, 150, respectively. In the illustrated embodiments, the supports 180, 182 are ring-shaped; however, as may be recognized by those of ordinary skill in the pertinent art, they may take any of numerous different shapes and/or configurations that are currently known or later become known.

(25) FIG. 4B is a cross-sectional view of the connector of FIG. 4A showing full interconnection of the male and female connectors. As seen in FIG. 4B, the first and second supports 180, 182 bolster the base of the first and second integral valves 122, 134 and increase the structural integrity and durability of the connector 110 in the open position. In the open, interconnected position, the first and second supports 180, 182 abut the integral valves 122, 134 to prevent failure of the valves. Another embodiment of the first and second supports 180, 182 is that they prevent the first and second integral valves 122, 134 from bending or deforming beyond a maximum, open or deflected position.

(26) The connectors of the present invention have numerous different applications in any of numerous different fields. For example, the connectors may be used to interconnect IV tubing, pouches and tubing, filling tanks and/or filling machines, and any of numerous other applications requiring fluid connections. As can be readily appreciated, the connectors of the present invention are particularly well suited for applications requiring an aseptic or sterile connection, or applications that require the prevention of any contact with the fluid being transferred (such as a toxic fluid).

(27) As may be recognized by those of ordinary skill in the pertinent art based on the teachings herein, numerous changes, modifications and improvements may be made to the above-described and other embodiments of the present invention without departing from the scope of the invention as defined in the appended claims. For example, the ports, valves, engaging portions, deflecting members, connector bodies, connector housings and means for releasably or otherwise connecting the connectors, may take any of numerous different configurations that are currently known, or that later become known. In addition, not all elements or all features disclosed herein are necessary, and if desired, additional elements or features may be added. Further, the elements or components of the connectors may be made of any of numerous different materials that are currently known, or that later become known. Still further, the connectors may be used to transport any of numerous different fluids that are currently known, or that later become known, such as drugs, pharmaceuticals, vaccines, ophthalmic products, creams, ointments, gels, beverages or food products, such as dairy, milk, cream, infant formula, chocolate, and industrial products, such as industrial liquids or gases. Still further, only one of the two connectors may require a valve (e.g., if only one side of the connection need be aseptic or sterile), and thus one connector (male or female) may be a conventional connector or may different from the other connector. Accordingly, this detailed description of the currently preferred embodiments is to be taken in an illustrative, as opposed to a limiting sense.
