Definitions

  • the invention relates to a connector for containers containing medicinal active ingredient, which connector makes it possible to transfer active ingredient from one container into another container.
  • EP 2 095 805 A2 discloses a connector for containers containing medicinal active ingredient, which connector comprises a first connection region for the connection of a glass vial, a second connection region for the connection of a flexible bag and an axially movable piercing element taking the form of a cannula which is sharpened on two sides.
  • the piercing element is mounted in an axially displaceable manner in a first housing section of a housing of the connector.
  • the first housing section is mounted in a telescopically displaceable manner on a second housing section. In the starting position of the connector, the first housing section and the second housing section are pulled apart.
  • the first housing section By connecting a glass bottle in the first connection region and by exerting a pressure on the glass bottle, the first housing section is displaced with respect to the second housing section.
  • a membrane arranged in the neck of the glass bottle and closing the glass bottle strikes one end of the piercing element. Pushing forward the glass bottle takes along the piercing element until it strikes by its other end against a membrane enclosing the flexible bag. Further pushing forward of the glass bottle causes both the membrane belonging to the flexible bag and also the membrane of the glass bottle to be pierced by the piercing element.
  • a limit stop for the movement of the piercing element limits the movement of the piercing element and ensures that not only the membrane belonging to the bag but also the membrane of the glass bottle is opened.
  • a disadvantage of this connector is that it comprises parts which are movable with the two housing sections and which have to be sealed with respect to one another. Furthermore, the connector comprises a large number of elements which make the production of the connector complicated and expensive.
  • the connector according to the invention for containers containing medicinal active ingredient comprises a first connection region for the connection of a first container, a guide element, a piercing element and a partition wall, wherein the guide element has a duct designed for transferring a medicinal active ingredient, the piercing element is arranged, at least in certain sections, in the duct and is axially movably guided within the duct by the guide element, and, by connecting a container, the piercing element can be moved from a starting position, in which the piercing element does not open the partition wall, into an end position, in which the piercing element opens the partition wall in order to transfer a medicinal active ingredient.
  • the guide element forms both the duct through which an active ingredient can be transferred and also forms a mount in which the piercing element can be displaced in an axially movable manner means that the guide element can adopt a dual function. Consequently, the number of elements of the connector can be reduced and the connector can be produced cost-effectively. It is also possible in this manner to reduce the number of interfaces and to improve the handling of the connector.
  • the connector according to the invention makes it possible in particular to transfer the medicinal active ingredient without risk of contamination.
  • the containers which can be connected or attached by the connector may be both closed containers, for example glass bottles, plastic bottles or bags, in particular flexible bags, and “open” containers, for example catheters or other lines, as are used, for example in infusion, transfusion, clinical nourishment, oncology, dialysis or other medical fields.
  • the medicinal active ingredient which can be transferred from one container to the other container by means of the connector may be a liquid or else a powder, for example.
  • the partition wall may be a flexible partition wall, for example consisting of an elastic material, in particular in the form of a membrane, or else, which is preferred, a rigid partition wall which is broken open or pierced by the piercing element.
  • the piercing element and the guide element are designed in such a way that a clearance for transferring a medicinal active ingredient remains between an outer face of the piercing element and an inner face, forming the duct, of the guide element.
  • the piercing element and the guide element are designed in such a way that the medicinal active ingredient is additionally or exclusively transferred by means of the piercing element.
  • the piercing element can be designed to be solid or as a hollow body. A combination of hollow body and solid body is also possible in principle.
  • the profile of the piercing element preferably changes along its axis, with the end section facing the partition wall being designed to break open or pierce the partition wall, and the end section facing the container to be connected being designed in such a way that a pressure can be exerted on the end section by means of the container, which pressure can be used to press the piercing element against the partition wall.
  • the end section facing the partition wall may, for example, be designed to taper with a linear or cross-shaped profile, while the other end section may be designed with, for example, a cross-shaped or round profile so as to form a bearing surface.
  • the end section facing the partition wall may be designed with a faceted finish or have a swaged tip.
  • the guide element and the partition wall are formed in one part, being integral in a particularly preferred embodiment.
  • the connector comprises a housing forming the first connection region.
  • Housing, guide element and partition wall are preferably formed in one part, particularly preferably integrally.
  • the one-part and possibly integral formation of a plurality of functional elements makes it possible to reduce the number of parts of the connector, and the production costs can be reduced.
  • piercing element, guide element, partition wall and/or housing are produced from a plastic, preferably polypropylene (PP) or a blend of polypropylene and styrene/ethylene-butylene/styrene (SEBS).
  • PP polypropylene
  • SEBS styrene/ethylene-butylene/styrene
  • piercing element, guide element, partition wall and/or housing may be injection moldings.
  • the piercing element can be produced from, for example, polycarbonate (PC) or polystyrene (PS).
  • the guide element comprises an end section which is designed to pierce a membrane of a container which can be connected into the first connection region, for example to pierce a rubber stopper of a glass vial.
  • the guide element thus comprises a further function.
  • a further element which is intended for piercing a membrane can be dispensed with in this manner.
  • the first connection region is designed as a Luer connection of a Luer lock, in particular as a male part.
  • the guide element is formed partially or completely by the central cone of the Luer connection.

  • FIGS. 1 to 10 show various views of a first embodiment of a connector 1 according to the invention for containers containing medicinal active ingredient.
  • the connector 1 comprises a first connection region 3 for the connection of a first container, a guide element 4 , a piercing element 5 , a partition wall 6 and a second connection region for the connection of a second container.
  • the first connection region 3 is designed here for the connection of a medicinal glass vial.
  • the second connection region 12 is designed here for the connection of a flexible bag.
  • the first connection region 3 and/or the second connection region 12 can of course also be designed for other containers, for example plastic bottles or transfer systems.
  • the connector 1 comprises a housing 9 with a substantially hollow-cylindrically shaped housing section 10 , forming the first connection region 3 , and a housing base 11 .
  • the guide element 4 is designed as a tubular hollow body with a duct 7 for the transfer of a medicinal active ingredient and is connected to the housing base 11 in the center of the housing base 11 .
  • One end of the guide element ends at the housing base 11 , while the other end projects into the connection region 3 and thus into the inner region of the housing section 3 .
  • the end section 8 of the guide element 4 that projects into the connection region 3 is sharpened or pointed in order to pierce through a membrane 14 of a container 2 to be connected in the connection region 3 .
  • the housing section 10 and guide element 4 are arranged axially in a common axis of symmetry 15 .
  • the connector 1 comprises a connecting means 13 which forms the second connection region 12 .
  • the connecting means 13 is of tubular design, arranged along the axis of symmetry 15 and is connected by one end to the rear side of the housing base 11 situated opposite to the connection region 3 .
  • the connecting means 13 comprises two welding lugs 16 formed with mirror-image symmetry for connecting the connecting means to a flexible plastic bag which is not represented in further detail.
  • the connecting means 13 comprises two reinforcing webs 17 extending laterally along the axis of symmetry 15 , these webs extending from the base 11 as far as the welding lugs 16 with mirror-image symmetry and having the purpose of reinforcing the connecting means.
  • the partition wall 6 takes the form of a membrane. It is arranged between the first connection region 3 and the second connection region 12 and, in the closed state, prevents the transport of a medicinal active ingredient between these two regions. Specifically, the partition wall 6 is arranged at the end of the guide element 4 facing away from the first connection region 3 and terminates flush with the rear side of the housing base 11 . Alternatively, instead of an arrangement of the partition wall 6 at an end of the duct 7 , an arrangement of the partition wall 6 within the duct 7 of the guide element 4 is also possible. Furthermore, the partition wall 6 can be arranged such that it is raised from the housing base 11 , for example is arranged in the manner of a cover on the opening of the duct 7 .
  • the partition wall 6 can be fastened to the housing base 11 via at least one predetermined breaking point, with the result that the partition wall can be broken open at the at least one predetermined breaking point by the piercing element 5 , and the duct 7 is opened in this way. In this case, piercing of the partition wall 6 can be dispensed with.
  • the partition wall 6 is designed as a wall with a sufficiently thin wall thickness so that it can be pierced and/or broken open by the piercing element 5 .
  • the partition wall is designed in such a way that, after the piercing/breaking-open operation, it remains opened upon a withdrawal of the piercing element 5 , which is preferred. It is also possible to design the partition wall 6 in such a way that it can close after a withdrawal of the piercing element 5 .
  • the housing 9 , guide element 4 , partition wall 6 and connecting means 12 are produced in one part and integrally from plastic, here from PP or a blend of PP and SEBS, as an injection molding, with the result that the connector can be produced in a particularly cost-effective manner. Also possible in principle is a multi-part construction and/or a construction composed of a plurality of different materials.
  • the piercing element 5 is designed as a solid rod.
  • the piercing element is arranged in the duct 7 and is axially movably guided within the duct 7 by the guide element 4 .
  • the piercing element 5 has a cross-shaped profile which is adapted in its outer dimensions to the inner diameter of the tubular guide element 4 , with the result that the piercing element 5 does not tilt.
  • profiles can also be used for the piercing element 5 , for example profiles with a triangular shape, star shape, square shape and/or cylinder shape.
  • the piercing element 5 can also be designed partially or completely as a hollow body and the transport of the medicinal active ingredient can take place partially or completely through the piercing element 5 .
  • the guide element 4 can also be designed with other profiles, for example a square or rectangular profile.
  • the piercing element 5 is releasably prefixed in a starting position in which the piercing element 5 does not open the partition wall 6 .
  • the piercing element 5 comprises two mutually opposite projections 18 which, in the starting position, releasably engage in two corresponding grooves 19 in the guide element 4 .
  • the piercing element can be released from the starting position and transferred into an end position.
  • the piercing element 4 opens the partition wall 6 ; see also FIGS. 6 to 9 .
  • the guide element 5 has two further grooves 20 into which the piercing element 4 can latch after opening the partition wall 6 and which prevent the unwanted release of the piercing element 4 from the guide element 4 .
  • the piercing element 4 can be provided for example with only one groove or further grooves, and in the case of a plurality of grooves they can be arranged in an offset manner for example.
  • the piercing element can be prefixed in the guide element by means of an oversize for example.
  • the piercing element 5 is sharpened or pointed at its end facing the partition wall 6 .
  • the piercing element 5 forms a bearing face in order to take up the pressure over as large an area as possible of a container to be connected and to prevent the piercing element 5 from unwantedly penetrating into the container, for example piercing a rubber stopper closure of the container.
  • the end of the piercing element 5 facing away from the partition wall is designed in this case as a planar face.
  • the piercing element 5 is produced in one part and integrally from a plastic, preferably from PP, PC or PS, as an injection molding.
  • the piercing element 5 can also be multi-part and/or consist of other materials, for example also of a metal, and/or of a plurality of materials.

During this movement, the piercing element 5 ′ clamped at the collar 24 is taken along by the female part 2 ′, and the partition wall 6 is broken open or pierced and opened by the sharpened or pointed end of the piercing element 5 ′, see FIG. 17 . The connection between the first connection region 3 ′ and the second connection region 12 is now opened, thereby allowing the transport of a medicinal active ingredient between a flexible bag connected to the connector 1 ′ in the connection region 12 or another container with a container connected by the Luer female part 2 ′.
  • connection region 3 ′ of the connector 1 ′ with piercing element 5 ′ can be covered by a manually removable cap (not shown).
  • the piercing element 5 ′ is preferably prefixed in its extended starting position, for example by means of a tongue-and-groove connection in a similar manner to that of the first embodiment. It is also possible to fix the piercing element 5 ′ in the end position, for example in order to prevent the piercing element 5 ′ from falling out when releasing the female part
  • the connectors 1 , 1 ′ according to the invention have the advantage that they can be produced cost-effectively. Furthermore, a sterile connection between two containers can be produced manually in a simple manner both reliably and quickly. In order to quickly transfer a medicinal active ingredient, guide element 4 , 4 ′ and piercing element 5 , 5 ′ can be designed with suitable profiles.
