Definitions

  • U.S. Patent No. 4,157,723 discloses a sterile connector system in which two connector members are locked together, preferably with opaque, thermoplastic wall portions being carried on a conduit about their periphery by transparent wall portions of the conduit. The opaque wall portions are brought together into facing contact, and then exposed to sufficient radiant energy to cause the opaque wall portions to fuse together to open an aperture through the fused wall portions, to provide sealed communication between the interiors of the conduits.
  • This may be a sterile connection, particularly when the opaque, thermoplastic wall portion has a high melting range of over essentially 200°C.
  • Ammann et al. U.S. Application Serial No. 005,749, filed January 23, 1979, and Boggs et al. Application Serial No. 27,575, filed April 6, 1979 dis close further improvements on the sterile connector system of the type disclosed in the patent cited above.
  • Bellamy et al. Application Serial No. 091,688, filed November 5, 1979 discloses sterile connector systems connected to vials or flexible bags, with the type of sterile connector being similar to the previouslycited patent applications.
  • the sterile connector preferably has auxiliary sealing means, which may be opened from the exterior in a manual way without breach of sterility.
  • the type of sterile connector systems described in the patent and applications cited above makes practical the long-felt need of providing a highly reliable sterile transfer of materials between various containers, so that, as stated above, partial units of blood may be used and the remainder sent back to storage, and other sterile solutions which are particularly subject to growth of bacteria upon contamination may be entered without the requirement for immediate use of the entire unit of sterile material.
  • a sterile connector system which comprises a first connector member defining a first, hollow housing having an opaque, thermoplastic wall, and a first port for flow communication to and from the first hollow housing.
  • a second connector member defines a second hollow housing having a transparent, thermoplastic wall, the transparent wall being capable of being p ⁇ si-cione ⁇ adjacent to and along the opaque wall, and a second port for flow communication to and from the second hollow housing.
  • Means are provided in the hollow housings permittin the application of radiant energy to the adjacently-positioned opaque wall and transparent wall, to melt at least a portion of the opaque wall by absorption of radiant energy applied, and also to melt at least a portion of the transparent wall- primarily by heat conduction from the opaque wall, to cause a hole to open between the two walls and fusion of the materials of the walls together.
  • each of the first and second connector members may be single, molded pieces of thermoplastic, for great simplification of manufacture and reduction of cost, with the first hollow housing being made of an opaque, thermoplastic material and the second hollow hous ing being of a transparent, thermoplastic material.
  • the radiant energy is directed through the second transparent hollow housing to impinge and be absorbed by the first hollow housing, so that heat is generated in the opaque wall of the first hollow housing by absorption of the radiation, which heat is then transferred by conduction to the transparent wall through which the radiation passes, to cause both of them to fuse together and to open a hole between them in a manner similar to the technique described in the previouslycited patent.
  • Each of the first and second ports of the hollow housings are oreferabiv in sealed flow communication with first and second containers, for the sterile retention and also sterile transfer of materials.
  • first hollow housing is tubular in shape and to have an opa ⁇ ue, thermoplastic end wall.
  • the second hollow housing is also preferably tubular, and is transparent, as stated above, having an open end and defining an interior, trans parent thermoplastic wall across the bore thereof.
  • the second port for flow communication to and from the second hollow housing may be at a position separated from the open end of the second, hollow, transparent tubular housing by the interior, transparent wall.
  • the first housing is telescopically inserted through the open end into the bore of the second housing, with the opaque end wall and the interior, trans parent wall of the respective housings being positioned together in adjacent, facing relation to each other within the second housing.
  • the radiant energy may be applied to pass through the wall of the transparent second housing, to impinge on the opaque end wall in sufficient intensity to heat it to the melting point.
  • the heat is transferred to the interior, transparent wall primarily by conduction so that the two walls fuse together and open an aperture for sterile connection.
  • the materials of the first and second connector members of this invention to be made of a substantially crystalline material such as poly (4-methyl-1-pentene) sold under the trademark TPX by Mitsui Chemical Company, or ether materials as described in the Boggs et al. application cited above.
  • the preferred substantially crystalline materials exhibit melting points above essentially 200°C.
  • the two walls fuse together so that a sealed aperture is formed between the two walls, with the surface being sterile because of the high temperatures encountered during the fusing and hole-opening step.
  • the opaque end wall and interior, transparent wall of the first and second connector members prefferably be inclined at an acute angle to the axes of the first and second housing, the angle being typically 30° to 60°. This permits the two wails which are to be melted to be more conveniently exposed to irradiation through the transparent, outer wall of the second connector member.
  • each housing may define one member of key and keyway means, to interact together to prevent relative rotation thereof.
  • first and second connector members when in tubular form, may be tapered to cooperatively define a luer-type seal therebetween for added sealing and mechanical support of the connector structure, above and beyond the sterile sealing which is provided by the fusion of the opaque end wall and interior, transparent wall.
  • Figure 1 is a partly schematic elevational view of the sterile connector system of this invention, connected to a pair of sealed collapsible containers, taken partly in section.
  • Figure 2 is a plan view of the first, opaque connector member of this invention.
  • Figure 3 is a longitudinal sectional view of the structure of Figure 2, but rotated 90° about its longitudinal axis.
  • Figmre 4 is a plan view of the second, transparent connector member of this invention.
  • Figure 5 is a longitudinal sectional view of the structure of Figure 4, but rotated 90° about its iongitudinal axis.
  • Figure 6 is a longitudinal sectional view of the connected first and second connector members of Figure 1.
  • Figure 1 shows a connector system of joined first connector member 10 and second connector member 12.
  • Each of the connector members is connected respectively to first and second ports 14, 16 which, in turn, are each connected to flexible plastic tubing 18, 20, in sealed manner, which is joined to containers for the sterile retention of various contents, for example collapsible plastic bags 22, 24.
  • Bags 22, 24 may be blood bags, as part of single or multiple blood bag systems for the collection and/or storage of blood and its various components such as plasma, packed red cells, platelets, or while cells.
  • bags 22, 24 may contain respective materials for mixing, for example lyopnilized medication in one bag and a carbohydrate solution in the other for total parenteral nutrition, or any other material for which sterile retention after mixing or transfer from one container to another is desired.
  • one or more of the containers 22, 24 may be a rigid or semi-rigid vial of a design and for purposes similar to that shown in the previously cited Bellamy et al. patent.
  • the connector system of this invention may be used for any prupose where it is desired to transfer the contents of one container to another for mixing or separation of components or the like, with reliable maintenance of sterility during and after the transfer.
  • the first connector member 10 is shewn in detail in Figures 2 and 3.
  • connector 10 may be a single, molded piece of TPX thermoplastic, sold by the Mitsui Chemical Company and filled for example with powdered charcoal, carbon black, or the like to render it opaque as described in the previously-cited Boggs et al. application.
  • First connector member 10 comprises a first hollow tubular housing 26 having an opaque, thermoplastic end wall 28 as an integral part thereof.
  • First port 16 is also provided for communication to and from hollow housing 26, being sealed to tubing 20 for aseptic communication with bag 24.
  • Flanges 32 and 33 are provided to facilitate the manual insertion of first connector member 10 into second connector member 12, and to also aid positioning of the membrane for sealing. Additionally, first connector 10 may carry a longitudinally disposed key member 34 to fit into a keyway defined in second connector 12, to assist in the retention of the two housings together until the respective opaque end wall and interior transparent wall are fused together, and also to prevent relative rotation of the connector members 10, 12.
  • the end of port 16 may define a pointed spike 36 for manual penetration of diaphragm 38 by the collapsing of bellows 40, to provide an auxiliary sealing device, for example as shown in the copending Dossin application Serial No. 196,966, filed October 14, 1980.
  • second connector member 12 is shown, also defining a hollow housing 42.
  • Second connector member 12 may also be an integrally molded single piece of thermoplastic material, for example made of the same TPX thermoplastic but free of opaque filler so that housing 42 is transparent.
  • Interior transparent thermoplastic wall 44 is defined across the bore of second connector member 12.
  • Second port 14 is defined, sealed to tubing 13 and separated from the open end 46 of second connecter 12 by interior transparent wall 44, so that the entire interior area of tubing 18 and port 56 may be retained in sterile manner as long as wall 44 remains intact.
  • Second connector 12 defines on its exterior a keyway 48, sealed from the exterior by an outer wall 50.
  • Keyway 48 is adapted to receive key member 34 in tight, gripping relation in area 52, to assist in the retention of the two members 10, 12 together and also to prevent rotation.
  • the outer portion of keyway 48 is flared outwardly for ease of assembly, to receive key member 34 as first connector 10 is manually thrust into second connector 12, and to direct key member 34 into the tight portion 52 of the keyway 48.
  • port 14 of housing 12 may optionally also carry a spike member 36 at its end, enclosed by a boot member 40, so that diaphragm 38 may be penetrated as desired by the manual manipulation of spike 36 and longitudinally collapsible boot member 40.
  • connector member 10 in use, as connector member 10, 12 are brought together by inserting connector member 10 into connector member 12, opaque end wall 28 and interior transparent wall 44 are brought into proximate, overlying relationship and preferably in essentially substantially abutting relationship.
  • connector member 10 may be slightly tapered in area 54 to match a corresponding taper in area 56 of connector member 12, so that the two connector members fit together in a luer-type sealing relationship for added sealing benefit, with the interaction of key 34 and keyway 48 providing a nonrotatable relationship.
  • the assembled connectors 10, 12 may then be exposed to a source of strong light 58, or other radiation such as infrared radiation, focused through a lens if desired, and directed through the outer wall of second housing 12 and interior wall 44, to impinge upon opaque end wall 28 and be absorbed thereby.
  • a source of strong light 58 or other radiation such as infrared radiation
  • the intensity of the radiation utilized should be sufficient to provide enought energy to heat opaque end wall 28 into its melting range which, as previously stated, is preferably in excess of 200°C. to obtain sterilizing action.
  • Membrane 44 is correspondingly heated, primarily by conduction of the heat from end wall 28, but also possibly by some direct absorption of radiation, although interior wall 44 is substantially transparent.
  • first connector 10 may also be transparent, with an opaque layer carried on end wall 28.
