Definitions
- the present disclosure relates to a fluid transfer device for use in medical and/or pharmacological applications, with a first adapter unit having a first sealing element and a second adapter unit having a second sealing element, wherein the first adapter unit and the second adapter unit are configured to have a fluid connection in a connected state between the first adapter unit and the second adapter unit and to prevent or to prevent the fluid transfer from the first adapter unit and the second adapter unit out in a non-connected or disconnected state.
- the present disclosure relates to a use of such a fluid transfer device for the transfer of drugs, in particular CMR drugs (drugs which are carcinogenic/causing, mutagenic and reprotoxic/toxic to reproduction) from a first container to a second container.
- CMR drugs drugs which are carcinogenic/causing, mutagenic and reprotoxic/toxic to reproduction
- the present disclosure relates to a closed drug transfer system with such a fluid transfer device and at least one first container, wherein the fluid transfer device is set up to provide a fluid connection between the first container and a second container or between the first container and a patient.
- Closed (drug) transfer systems also called “Closed System Transfer Devices - CSTD" are known from the prior art and are typically used when dangerous or harmful drugs are transferred from one container to another container or from one container to a patient be transferred.
- closed drug delivery systems are used to deliver CMR drugs, i.e. carcinogenic, mutagenic and mutagenic transfer reprotoxic (“reprotoxic”) drugs from an ampoule to a syringe, or from the syringe to an IV bag, or from the IV bag to a patient.
- CMR drugs i.e. carcinogenic, mutagenic and mutagenic transfer reprotoxic (“reprotoxic”) drugs from an ampoule to a syringe, or from the syringe to an IV bag, or from the IV bag to a patient.
- reprotoxic reprotoxic
- CMR medicines or CMR drugs are used, for example, in cancer therapy and in therapeutic applications combat particularly growth-intensive tumor cells.
- these drugs have carcinogenic, mutagenic or reprotoxic properties due to their mechanism of action.
- it is essential to prevent medical staff who are not being treated with CMR drugs from being exposed to these dangerous or harmful drugs when preparing or administering CMR drugs, or from being directly/immediately in contact with them contact comes.
- closed drug delivery systems should therefore prevent the transfer of impurities/contamination from the environment into the closed system and the escape of dangerous/harmful drug or vapor concentrations from the closed system, in particular mechanically, as far as possible.
- a fluid transfer device/connection system/coupling system which consists of two (adapter) units/components/parts/coupling partners that can be connected to each other to transfer the CMR drugs via to enable the fluid transfer device, and which can be separated from one another and in the separated state prevent or prevent fluid transfer out of the two units.
- the coupling/connection/contact points of the two units should be as dry as possible after separating them, i.e. the CMR drugs should not leak or drip on the surfaces of the coupling partners in order to protect the environment from contamination.
- coupling systems/fluid transfer devices which have self-sealing properties and largely enable dry connection and dry separation of the coupling partners have become increasingly important in the preparation and administration of ready-to-use CMR drugs in recent years.
- Closed drug transfer systems with a fluid transfer device or fluid transfer devices which in a connected state provide a fluid connection between a first (adapter) unit and a second (adapter) unit and in a non-connected or disconnected state the fluid transfer from the first (adapter) ) Unit and the second (adapter) unit prevent / prevent, are for example from WO 2016/051390 A1, WO 2016/199133 A1, WO 2016/147178 A1, WO 2017/109776 A1, US2016/058667 A1, EP 2 139442 B1, EP 2606872 B1, US 8511 352 B2, US 2018/0200498 A1, EP 2753396 B1 and US 9345641 B2.
- Known fluid transfer devices essentially have in common that they are connected by a translational pressing movement of the two (adapter) units towards one another/by applying opposing force to the two (adapter) units in the axial direction according to the plug-socket principle.
- a translational pressing movement of the two (adapter) units towards one another/by applying opposing force to the two (adapter) units in the axial direction according to the plug-socket principle.
- a fluid transfer device which can be used as a part/component of a closed drug transfer system which in its connected state enables fluid transfer through it or provides a fluid connection through it which in its disconnected/unconnected state allows fluid transfer from the Coupling partners / adapter units out prevents or prevented, and which in particular achieves that the coupling surfaces of the coupling partner / adapter units are dry in the separated state, which means that they have as little or no moisture residues remain.
- the fluid transfer device should be easy to handle, provide a flow rate through it that is suitable for the application, not be too large in terms of its size, and have easily accessible and thus disinfectable coupling (surfaces).
- the present disclosure initially relates to a fluid transfer device for use in medical and/or pharmacological applications, with a first adapter unit having a first sealing element and a second adapter unit having a second sealing element, the first adapter unit and the second adapter unit being set up in a connected state To provide fluid connection between the first adapter unit and the second adapter unit and to prevent/prevent a fluid transfer from the first adapter unit and the second adapter unit in a non-connected or disconnected state, wherein the first adapter unit and the second adapter unit are formed by a combined pushing movement (translational) to each other (towards) and rotational (relative) to each other the fluid connection between the first To produce the adapter unit and the second adapter unit only after setting a constant/defined/predetermined pressure, which the first sealing element and the second sealing element apply against one another.
- the first sealing element and the second sealing element are only fully penetrated by a needle or an interface/an interface/contact point of the first sealing element and the second sealing element is only penetrated by the needle when the two sealing elements already have the desired, constant pressure against one another bring up.
- the first sealing element and the second sealing element When separating the two adapter units, the first sealing element and the second sealing element preferably apply the defined/constant/predetermined pressure against each other until the needle has been pulled back over the interface/the interface of the first sealing element and the second sealing element.
- the mechanical separation of the two adapter units thus preferably only takes place when the needle has been withdrawn again.
- the fluidically connected state and the separate/fluidically non-connected state of the fluid transfer device are only produced when the constant/defined pressure is applied to the two sealing elements.
- the result of this is that hardly any fluid residues/fluid droplets are left behind on the coupling surfaces of the sealing elements, if possible.
- dry connection and dry separation are thus made possible.
- the first adapter unit and the second adapter unit are thus advantageously set up, in addition to the connected state and the unconnected or disconnected state.
- separate state to assume a transitional state in which the first adapter unit and the second adapter unit are attached to one another and the first sealing element and the second sealing element bear against one another and apply the constant or defined pressure against one another, and still no fluid connection between the first adapter unit and the second adapter unit is provided.
- the adapter units are preferably not brought directly from the non-connected/disconnected state by plugging them into one another (according to the plug-socket principle) into the fluidically connected state, but the two adapter units also assume a defined third state, viz the transition state.
- the functions “setting up a fluid connection” and “applying the defined, constant pressure against one another by the two sealing elements” are therefore preferably separated functionally and temporally. In other words, in a first step the constant pressure is applied against one another by the two sealing elements and in a subsequent second step the fluid connection between the two adapter units, in particular by the needle, is first established.
- the functional and temporal separation of the two functions mentioned is achieved in particular in that the first adapter unit and the second adapter unit are set up to move from the non-connected or non-connected position by pressing one another and rotating one another by a first predetermined angle to be brought into the transitional state from the disconnected state, and to be brought into the connected state from the transitional state by continued rotation through a second predetermined angle.
- An advantageous aspect of the present disclosure is the fact that a combined pushing and rotating movement by a user, for example medical staff, is required to set the (fluidically) connected state of the fluid transfer device. It is therefore not sufficient according to the present disclosure to move the two adapter units towards one another in a translatory manner and to plug one of the adapter units into the other of the adapter units according to the plug-socket principle.
- a rotational movement or rotary movement In addition to the translational Movement is required, particularly when the two adapter units are already pressed against one another, a rotational movement or rotary movement.
- Rotating through the first predetermined angle preferably causes the two adapter units to change from the disconnected/unconnected state to the transitional state. Starting from the transitional state, a rotation through the second predetermined angle preferably takes place in order to transfer/spend the two adapter units from the transitional state to the connected state.
- the two adapter units can preferably be brought back into the transitional state by a (opposite or continued) rotary movement by the second predetermined angle, and, starting from the transitional state, by a continued rotary movement in the selected direction of rotation by the first predetermined angle again be transitioned to the unconnected/disconnected state.
- the second adapter unit has a hollow needle forming a fluid channel, and the hollow needle is received in the second sealing element in the non-connected or disconnected state and the transitional state and penetrates into/through the interface between the first sealing element and the second sealing element only when the first adapter unit and the second adapter unit are brought from the transition state to the connected state.
- the hollow needle preferably has a so-called pencil point tip. More preferably, the hollow needle has a lateral opening at/near its tip.
- the hollow needle advantageously only establishes a fluidic connection between the two adapter units when it has penetrated the interface between the first sealing element and the second sealing element and also completely through the first sealing element of the first adapter unit.
- An inner diameter of the hollow needle and a size of the lateral opening are preferably set suitably for setting a flow rate through the fluid transfer device.
- a preferred embodiment is characterized in that the second adapter unit has a substantially hollow-cylindrical / sleeve-shaped component and a substantially cylindrical component, wherein the cylindrical component in the hollow-cylindrical/sleeve-shaped component (in particular at a distal end of the second adapter unit), and wherein a rotation/rotation of the hollow-cylindrical/sleeve-shaped component causes a translational movement of the hollow-cylindrical/sleeve-shaped component and the cylindrical component relative to one another.
- proximal and distal are defined at this point for the present application as follows: “proximal” means “closer to a user (medical personnel)” and “distal” means “further from a user (medical personnel)”. ', assuming that when connecting and disconnecting the fluid transfer device, the second adapter unit is located closer to the user, i.e. located proximally, and the first adapter unit is located further from the user, i.e. located distally.
- the second adapter unit preferably has at least two parts/components that can be rotated relative to one another, and twisting/twisting/rotating the two parts/components relative to one another preferably causes a translational movement of the two parts/components (relatively) to one another.
- the second adapter unit is thus set up to convert a rotary movement applied to its hollow-cylindrical component by a user (medical staff) into a translational movement of the hollow-cylindrical component and the cylindrical component relative to one another.
- a user medical staff
- the cylindrical component preferably migrates/shifts in the proximal direction, i.e. further into the interior of the hollow-cylindrical component or the hollow-cylindrical component preferably shifts in the distal direction when the adapter unit moves from the separated state into the transitional state and further from the transitional state into the connected state.

- the peg-like projection of the cylindrical component migrates during the rotation of the hollow-cylindrical component in/along the connecting link/link path, as a result of which the axial/translational displacement of the two components relative to one another is brought about.
- the pin-like projection is preferably located in a section of the connecting link/link track without an incline, ie in a section which only extends in the circumferential direction.
- the link/link track advantageously has at least one section without an incline. If the peg-like projection is located in the section of the connecting link without an incline, there is advantageously no further translational displacement of the cylindrical component and the hollow cylindrical component relative to one another and thus no further translational displacement of the hollow cylindrical component relative to the first adapter unit. Of the The user thus advantageously recognizes that the connected state of the two adapter units has been reached when he can no longer determine any relative translational displacement.
- the link/link track preferably has a first section, in which the link extends from a first distal stop in the circumferential direction and in the axial direction (distal-proximal) of the hollow-cylindrical component, a second section, which is the section without a pitch, and a third section which, starting from the second section, extends in the circumferential direction and in the axial direction (proximal-distal) of the hollow-cylindrical component towards a second distal stop.

- the closed drug transfer system 2 has a fluid transfer device 4 with a first adapter unit 6 and a second adapter unit 8 .
- the first adapter unit 6 and the second adapter unit 8 are shown in FIG. 1 in an unconnected or disconnected state.
- the first adapter unit 6 and the second adapter unit 8 can be brought into a connected state in which a fluid connection is provided between the first adapter unit 6 and the second adapter unit 8 .
- dangerous/harmful drugs such as CMR drugs can be transferred from a first container 10 via the fluid transfer device 4 to a second container 12 or a patient 14 without contamination.
- the fluid transfer device 4 is thus basically set up to establish a fluid connection between the first container 10 and the second container 12/the patient 14.
- the first container 10 is, for example, an ampoule, and a fluid from the ampoule can be transferred via the fluid transfer device 4 to a second container 12 designed as a syringe.
- the first container 10 can also be a syringe, and a fluid can be transferred from the syringe via the fluid transfer device 4 to a second container 12 designed as an infusion bag.
- the first container 10 can also be an infusion bag, and a fluid can be brought from the infusion bag to the patient 14 via the fluid transfer device 4 .
- the first adapter unit 6 and the second adapter unit 8 are each essentially cylindrical.
- the second adapter unit 8 is located closer to a medical staff/user and is therefore arranged proximally in relation to the first adapter unit 6 or the first adapter unit 6 is arranged distally in relation to the second adapter unit 8 .
- the first adapter unit 6 has a first connection 16 at its distal end, which is designed here as a female Luer lock connection.
- the first connection 16 is part of a first connection part 18 which, when the first adapter unit 6 is in the assembled state, is firmly connected to a (first) essentially hollow-cylindrical component 20 .
- the connection part 18 is designed in the manner of a socket and is simply inserted into the hollow-cylindrical component 20 .
- the connecting part 18 has an inner fluid channel 22 which runs through the first adapter unit 6/in an axial direction of the first adapter unit 6 up to a first sealing element 24 .

- the first sealing element 24 has a first cylindrical section 28 and a second cylindrical section 30 .
- a diameter of the first cylindrical section 28 is larger than a diameter of the second cylindrical section 30.
- the first cylindrical section 28 rests on the proximal wall 26 and on an inner lateral surface 32 of the hollow-cylindrical component 20 from the inside.
- the second cylindrical portion 30 extends through a first through hole 32 provided in the proximal wall 26 and protrudes with respect to the proximal wall 26 in the proximal direction.
- the hollow-cylindrical component 20 of the first adapter unit 6 has a circumferential flange section 36 projecting radially outwards at its proximal end.
- the Flange section 36 has a multiplicity of (here six) recesses/cutouts/material cutouts 38 .
- the recesses 38 are evenly distributed in the circumferential direction and there are two recesses 38 diametrically opposite one another.
- the second adapter unit 8 has a second connection 40, which in the present case is designed as a male Luer lock connection.
- the second connection 40 is part of a second connection part 42 which, when the second adapter unit 8 is in the assembled state, is firmly connected to a (second) essentially hollow-cylindrical component 44 .
- the connection part 42 is designed in the manner of a plug-in sleeve and is simply inserted into the hollow-cylindrical component 44 .
- the connecting part 42 has a needle receptacle 46 in which a flea needle 48 is held/attached.
- the second adapter unit 8 also has an essentially cylindrical component 50 which is accommodated in the hollow-cylindrical component 44 at a distal end of the second adapter unit 8 .
- the cylindrical component 50 has a pin-shaped projection 52 protruding radially outwards (from a lateral surface).
- the projection 52 is accommodated in a link/link track 54 of the hollow-cylindrical component 44 .
- the link/link track 54 is designed as a groove-like recess and essentially has a first section 56, in which the link 54, starting from a distal stop 58, extends like a thread/in both the circumferential direction and the axial direction (distal-proximal), i.e.
- a second section 60 which is a section without a pitch, i.e. a section in which the connecting link 54 extends only in the circumferential direction
- a third section 62 which, starting from the second section 60, threads in both the circumferential direction and the axial direction ( proximal-distal), ie obliquely, towards a second distal stop (not shown) extends.
- the cylindrical component 50 of the second adapter unit 8 has a second sealing element 64 on the inside.
- the second sealing element 64 is an elastic sealing element and consists of an elastomer.
- the second sealing element 64 extends in the axial direction approximately over the entire length of the cylindrical component 50.
- the second Sealing element 64 has a first cylindrical section 66 and a second cylindrical section 68 .
- a diameter of the first cylindrical section 66 is larger than a diameter of the second cylindrical section 68.
- the first cylindrical section 66 bears on a distal wall 70 and on an inner lateral surface 72 of the cylindrical component 50 from the inside.
- the second cylindrical portion 68 extends through a second through hole 74 provided in the distal wall 70 and protrudes in the distal direction with respect to the distal wall 70 .
- the cylindrical component 50 of the second adapter unit 8 has two diametrically opposite engagement elements 76 which each have an elastically resilient arm/snap arm 78 and a latching hook 80 .
- the engagement elements 76 project in the distal direction in relation to a distal end of the hollow cylindrical component 44 and in relation to the distal wall 70 of the cylindrical component 50.
- the distal wall 70 is arranged in the axial direction approximately at the level of the distal end of the hollow-cylindrical component 44 or can also project somewhat in the distal direction with respect to the distal end of the hollow-cylindrical component 44 .
- the engagement elements 76 are biased radially outwards (into a non-engagement state) and are each received in a receiving recess 82 provided in the hollow-cylindrical component 44 .
- the receiving recesses 82 are groove-like/trough-shaped/channel-shaped recesses in the hollow-cylindrical component 44.
- Fig. 4 and Fig. 5 each show a transitional state of the two adapter units 6, 8.
- Fig. 6 and Fig. 7 each show a connected state of the two adapter units 6, 8.
- the two adapter units 6, 8 go when they are connected to each other, first from the unconnected/disconnected state (see figs. 1 to 3) to the transitional state (see figs. 4 and 5) and only then from the transitional state to the connected state (see figs. 6 and 7) above.
- a user/medical staff presses the the two adapter units 6, 8 towards each other (in translation or in the axial direction of the two adapter units 6, 8), so that the first sealing element 24, in particular the protruding second cylindrical section 30 of the first sealing element 24, against the second sealing element 64, in particular the projecting second cylindrical portion 68 of the second sealing member 64, is pressed.
- the distal wall 70 of the cylindrical component 50 of the second adapter unit 8 is now in contact with or at least very close to the proximal wall 26 of the hollow cylindrical component 20 of the first adapter unit 6 .
- the user/medical staff preferably orients the two adapter units 6, 8 in such a way that the engagement elements 76 of the second adapter unit 8 are arranged in the same position as the recesses 38 of the first adapter unit 6 in the circumferential direction.
- the recesses 38 serve in particular as engagement element receptacles 84 and are preferably adapted in their shape and size to the engagement elements 76 , in particular to the latching hooks 80 of the engagement elements 76 .
- the user/the medical staff rotates the two adapter units 6, 8 relative to one another.
- the user rotates the hollow-cylindrical component 44 (and the second connection part 42, which is of course firmly connected to the hollow-cylindrical component 44) in a clockwise direction. Due to the pressure that the user applies from the first adapter unit 6 to the cylindrical component 50 of the second adapter unit 8, the first adapter unit 6 and the cylindrical component 50 of the second adapter unit preferably remain at rest, i.e. do not rotate.
- the first adapter unit 6 can no longer be moved/separated from the cylindrical component 50 of the second adapter unit 8 and also can no longer be rotated relative to the cylindrical component 50 of the second adapter unit 8 .
- the first adapter unit 6 and the cylindrical component 50 of the second adapter unit 8 are thus fixed/connected to one another in a defined manner.
- the first sealing element 24 particularly its protruding second cylindrical portion 30
- the second sealing element 64 particularly its protruding second cylindrical portion 68
- the two sealing elements 24 and 64 therefore exert a force on one another/against one another, which forces the first adapter unit 6 away from the second adapter unit 8 .
- the engagement elements 76 are accommodated in the engagement element receptacles 78 and exert a counterforce which prevents the two adapter units 6, 8 from separating from one another.
- the two sealing elements 24, 64 can thus no longer reach their relaxed initial state in the transitional state and thus exert a constant, defined, predetermined force or a constant, defined, predetermined pressure on one another.
- the two adapter units 6, 8 preferably reach the transitional state after a predetermined rotation through a first predetermined angle a.
- the flea needle 48 which moves together with the hollow-cylindrical component 44 and the second connection part 42, is still in the second sealing element 64 in the transitional state. That is, the flea needle 48 is in the transitional state an interface (an interface) 86 between the first sealing element 24 and the second sealing element 64 does not yet exist penetrated.
- the predetermined, constant, defined pressure is first set at the interface 86 between the first sealing element 24 and the second sealing element 64 before the interface 86 is pierced by the hollow needle 48 .
- the hollow-cylindrical component 44 is rotated further clockwise by a second predetermined angle ß, the pin-shaped projection 52 of the cylindrical component 50 moves further along the first section 56 of the connecting link 54.
- the hollow-cylindrical component 44 (and thus also the hollow needle 48) further translated (in the distal direction).
- the hollow needle 48 (pencil point needle) completely penetrates the interface 86 between the first sealing element 24 and the second sealing element 64 and also the first sealing element 24 of the first adapter unit 6 .
- the connected state of the two adapter units 6, 8 is reached.
- the pin-shaped projection 52 is in the second section 60 of the link 54, which extends only in the circumferential direction.
- a fluid for example a CMR drug
- a fluid can flow into an inner fluid channel 88 of the hollow needle 48 via the second connection 40, flow out of the inner fluid channel 88 of the hollow needle 48 via a lateral opening 90 of the hollow needle 48, and via the inner fluid channel 22 the first adapter unit 6 and the connection 16 leave the first adapter unit 6 and thus the entire fluid transfer device 4 again.
- the fluid can also flow into the inner fluid channel 22 of the first adapter unit 6 via the connection 16 of the first adapter unit 6, through the lateral opening 90 of the hollow needle 48 into the inner fluid channel 88 of the hollow needle 48, as well as the second adapter unit 8 and thus the leave the entire fluid transfer device 4 again via the second connection 40 .
- the fluid transfer device 4 can again be switched from the connected state of the two adapter units 6, 8 via the transition state to the unconnected/disconnected state to be spent. Starting from the connected state of the two adapter units 6, 8, the user can turn/rotate both clockwise and counterclockwise.
- the peg-shaped projection 52 migrates from the second section 60 of the link 54 back into the first section 56 of the link 54 and thus back to the first distal stop 58. With a clockwise rotation, the peg-shaped projection 52 moves from the second portion 60 of link 54 into third portion 62 of link 54 and toward the second distal stop (not shown).
- the first sealing element 24 and the second sealing element 64 bring the defined/constant/predetermined pressure against each other until the flea needle 48 again passes the interface 86 of the first sealing element 24 and the second sealing element 64 has been withdrawn.
- the mechanical separation of the two adapter units thus only takes place when the flea needle 48 has already been completely withdrawn again. It is therefore the case that the fluidically connected state and the fluidically non-connected state of the fluid transfer device 4 are only produced when the constant/defined/predetermined pressure is applied to the two sealing elements 24, 64.
- the first sealing member 24 and the second sealing member 64 are each reclosable/self-sealing sealing members. This means that when the flea needle 48 is pulled back again, the first sealing element 24 seals the first passage opening 34 and the second sealing element 64 seals the second passage opening 74 . Thus, fluid transfer out of the first adapter unit 6 and the second adapter unit 8 in the unconnected state/disconnected state is prevented.
- the second sealing element 64 is very large or voluminous. This is accompanied by relatively high friction between the second sealing element 64 and the hollow needle 48 .
- FIG. 8 shows an alternative exemplary embodiment, according to which the second sealing element 64 is designed to be smaller, in particular with a smaller axial extension. In the exemplary embodiment shown in FIG.
- a third sealing element 92 and an annular/sleeve-shaped spacer element 94 are provided.
- the second sealing element 64, the spacer element 94 and the third sealing element 92 are accommodated (in this order) in the cylindrical member 50 and in abutment/contact with each other (the spacer element 94 is located between the two sealing elements 64, 92).
- FIG. 9 shows an alternative exemplary embodiment, according to which the cylindrical component 50 has two guide elements 96 in the form of projections in the shape of arcs of a circle and the first adapter unit 6 has two guide element receptacles 98 in the form of recesses in the flange section 36 .
- the flange section 36 is not circumferential, but is interrupted in the circumferential direction for the guide element receptacles 98 .
- the shape and size of the arc-shaped projections are adapted to the interruptions in the flange section 36 .
- the first adapter unit 6 can no longer rotate with respect to the cylindrical component 50 of the second adapter unit 8.
- the engagement members 76 engage the flange portion 36 directly (i.e., no recesses 38 are required in the flange portion 36). It is thus the case that the flange portion 36 itself forms the engaging element receptacle 84 .
