Definitions
- the invention relates to a coupling system for a closed fluid transfer system.
- CMR drugs which are used, for example, in cancer therapy and whose therapeutic application is primarily aimed at damaging growth-intensive tumor cells, have a significant potential risk outside of the actual therapeutic application. Due to their mechanism of action, such substances are in part self-carcinogenic, which is why contact with people who are not in therapy should be avoided. For CMR drugs, therefore, more and more closed ones are used in the manufacture of ready-to-use preparations
- CSTDs Solid System Transfer Devices
- An important component of such CSTDs are coupling systems that enable the safe transfer of CMR drugs or other substances and after disconnecting the connection, lock them dry in order to protect the environment from contamination, e.g. through leaks or the formation of drops on the surfaces of the coupling elements.
- Coupling systems of this type are generally associated with the terms “dry connection”, “automatic self-sealing technology” or “closed connection” and are essential for realizing closed fluid transfer systems.
- the object of the present invention is to provide a coupling element, a mating coupling element and a coupling system for a closed fluid transfer system in which the respective coupling surfaces close dry in the disconnected state and can be easily and safely handled.
- a coupling system for a closed fluid transfer system which comprises: at least one coupling element for a closed fluid transfer system, comprising: a coupling element housing, the coupling element housing having a housing section which at least partially surrounds a sealing element receptacle with respect to the longitudinal axis in the axial direction and on the inside facing the sealing element has a coupling element housing threaded portion; and at least one mating coupling element for coupling with the coupling element, comprising: a mating coupling element housing, the mating coupling element housing having a mating coupling element guide structure; wherein the coupling element housing thread section of the coupling element is designed such that the mating coupling element guide structure and the sealing element receiving guide structure can be moved together, in particular in a predetermined positional relationship to one another, guided over the coupling element housing thread section.
- the coupling system for a closed fluid transfer system comprises at least one coupling element for a closed fluid transfer system and at least one mating coupling element for a closed fluid transfer system.
- the coupling element for a closed fluid transfer system comprises a coupling element housing with a fluid connection and a coupling side, the coupling element housing having a longitudinal axis extending from the fluid connection in the direction of the coupling side, a mandrel with at least one fluid opening which is held in a mandrel receptacle of the housing arranged on the fluid connection and extends in the direction of the longitudinal axis into the coupling element housing, the at least one fluid opening being arranged in an end section of the mandrel facing the coupling side, a sealing element receptacle arranged in the coupling element housing on the coupling side, a sealing element arranged in the sealing element receptacle, the The coupling element housing has a housing section which surrounds the sealing element receptacle at least in sections in relation to the longitudinal
- the sealing element receiving position with the maximum distance from the fluid connection corresponds to a position of the sealing element receiving position in a disconnected state, while the sealing element receiving position with the minimum distance from the fluid connection is preferably present when a connected state is reached which is provided for a fluid connection with a mating coupling element.
- the term "sealing element receiving position" does not refer to a position for receiving the sealing element, but to a position of the sealing element receiving element itself.
- thread in relation to the coupling element housing thread section or also in the following is not restricted to an isometric thread or a thread with inclined thread flanks, but generally includes a structure in which a guide structure is helical.
- the coupling element housing thread section has a height / length of the thread in the direction of the longitudinal axis that is greater than the height / length of the sealing element receiving guide structure in this direction
- a further guide structure of an element to be connected such as the mating coupling element guide structure described below, can also be used Counter-coupling element, together with the sealing element receiving guide structure in the coupling element are guided housing thread section.
- the thread pitch is designed in particular such that the sealing element receptacle and the element to be connected are held with a predetermined surface pressure to each other during their common guidance over the coupling thread section until the sealing element receptacle position is reached with a minimal distance from the fluid connection.
- the thread pitch is particular therefore constant, because this also ensures constant surface pressure over the guide path.
- the guide structure of an element to be connected such as the mating coupling element guide structure of a mating coupling element
- the following statements on the guidance of the sealing element receiving guide structure in the coupling element housing threaded section can be transferred analogously to the common guide. Accordingly, for the sake of simplicity, the guide structure of the element to be connected is not explicitly referred to again every time.
- the mating coupling element according to the invention for coupling to the coupling element comprises a mating coupling element housing with a mating coupling element fluid connection and a mating coupling side, wherein the mating coupling element housing has a mating coupling element housing extending from the mating coupling element fluid connection in the direction of the mating coupling side and is arranged in the mating coupling element housing together with a mating element housing
- Counter-coupling element housing forms at least part of a counter-coupling-side end face of the counter-coupling element, the counter-coupling element housing having a counter-coupling element guide structure which is designed such that the counter-coupling element can be moved in a guided manner via the coupling element housing thread section of the coupling element in the direction of the longitudinal axis relative to the coupling element.
- the mating coupling element guide structure can be designed, for example, as at least one projection pointing radially outward with respect to the longitudinal axis.
- the height of the projection in the direction of the longitudinal axis is in particular less than or equal to the difference between the thread pitch of the coupling element housing thread section in the longitudinal direction and the height of the sealing element receiving guide structure in the longitudinal direction in order to be able to be guided together with the sealing element receiving guide structure in the coupling element housing thread section.
- the height of the mating coupling element guide structure in The longitudinal direction can be coordinated according to the surface pressure to be provided between the mating coupling element sealing element and the sealing element of the coupling element.
- the mating coupling element guide structure can also be designed to be elastic in the longitudinal direction, so that, starting from a relaxed initial state, the mating coupling element guide structure can be compressed in the longitudinal direction. In the initial state, the height of the counter-coupling element guide structure can thus also be greater than the difference indicated above. Due to the elasticity of the mating coupling element guide structure, deviations from a constant thread pitch can also be compensated for in the longitudinal direction. In this way, the guided movement in the coupling housing section can also require a certain force to be applied, so that the risk of unintentional movement, in particular with regard to a pretensioning force applied by the coupling element, is reduced.
- the mating coupling element guide structure can also be exchangeable, for example, it can be screwed onto the mating coupling element as an annular element.
- the coupling system according to the invention is configured in such a way that the fluid opening of the coupling element in a state connected to the mating coupling element, in which the sealing element receptacle is in the position with the minimum distance to the fluid connection of the coupling element, is at least partially arranged on a side of the mating coupling element sealing element of the mating coupling element facing the mating coupling element fluid connection is.
- the sealing element receptacle By moving the sealing element receptacle from a position with a maximum distance from the fluid connection to a position with a minimum distance from the fluid connection and corresponding movement of the mating coupling element through the common guide in the coupling housing thread section, the mating coupling-side end face of the mating coupling element sealing element and the coupling-side end face of the sealing element of the coupling element at least in the area of the mandrel lie against one another in a fluid-tight manner, the sealing element of the Coupling element and the mating coupling element sealing element moved in the longitudinal direction along the mandrel in the direction of the fluid connection.
- the coupling system is configured in such a way that the sealing element and the mating coupling element sealing element are moved together in the direction of the fluid connection of the coupling element so far that the fluid opening of the mandrel of the coupling system is in a connected state in which the sealing element receptacle is in the position at a minimal distance from the fluid connection of the coupling element, protrudes at least partially, in particular completely on a side of the mating coupling sealing element facing away from the mating coupling element-side end face into a mating coupling element fluid channel encompassed or formed by the mating coupling element housing. Accordingly, the fluid opening is continuously sealed by the sealing element and the mating coupling sealing element until shortly before the connected state is reached.
- any fluid still on the mandrel can be stripped off the mating coupling element sealing element, so that the risk of a fluid escaping during or after disconnection is reduced.
- the coupling element housing thread section of the coupling element is designed such that the mating coupling element guide structure and the sealing element receiving guide structure can be moved together, in particular in a predetermined positional relationship to one another, guided over the coupling element housing thread section.
- the predetermined positional relationship can, for example, correspond to a position of the sealing element of the coupling element and the mating coupling element sealing element in which the mutually facing surfaces of the sealing element of the coupling element and the mating coupling element sealing element abut with a predetermined surface pressure.
- This can be achieved, for example, by a constant thread pitch in connection with corresponding dimensioning of the heights of the sealing element receiving guide structure and the mating coupling element guide structure are provided in the longitudinal direction.
- the at least one fluid opening is arranged in the sealing element when the sealing element receptacle with the sealing element is in the position at the maximum distance from the fluid connection.
- the sealing element receptacle has a sealing element receiving groove which extends from an end face facing the coupling side in the direction of the longitudinal axis in the direction of the fluid connection and is designed in such a way that a mating coupling element guide structure section, which comprises a mating coupling element guide structure, can be received at least in sections in the sealing element receiving groove.
- the sealing element receiving groove thus forms a section which is set back in the direction of the fluid connection in relation to the coupling-side end face and which serves as a stop.
- the sealing element receiving groove can also serve as a positioning aid for an element to be connected, such as the mating coupling element.
- the sealing element receiving guide groove can be designed, for example, as an outer, recessed section which is annular in the radial direction in relation to the longitudinal axis.
- the coupling element housing inner wall can surround this section in such a way that an annular receiving section is thereby formed for the element to be connected, which is limited in the radial direction with respect to the longitudinal axis on the outside by the coupling element housing or its inner wall.
- a section of the element to be connected engages in the sealing element receiving groove, for example until it reaches the stop formed by the sealing element receiving groove, this section covers that from the stop in the direction of the coupling side formed part of the sealing element receptacle.
- the connection of the coupling element with an element to be connected can be further sealed.
- a position of the element to be connected can thereby also be defined, in which a guide structure assigned to it can be introduced into the coupling element, threaded housing section, together with the sealing element receiving guide structure.
- the coupling element housing thread section is designed as an internal thread in which the sealing element receiving guide structure can be received.
- the sealing element receiving guide structure can thus be formed in a simple manner. In principle, however, it is also possible to design the coupling element housing thread section as an external thread, the sealing element receiving guide structure being designed at least in sections as an internal thread corresponding to this.
- the coupling element housing thread section has at least two mutually separate, in particular at least two mutually opposite, thread turns.
- the sealing element receiving in the coupling element housing thread section can be guided in a more stable position, since this prevents the sealing element receiving from tilting.
- the number of thread turns can, however, also be less than the number of sealing element receiving guide structures, for example to insert the sealing element seat in different orientations in the coupling element housing and / or to provide different movements of the sealing element seat through different thread turns.
- at least one thread of the coupling element housing thread section extends over an angle of less than 360 °, in particular over an angle of substantially 180 °, with respect to the longitudinal axis.
- the guided movement of the sealing element receptacle can thus take place over a limited angle of rotation, which simplifies handling.
- a shortened angle of rotation that is to say an angle of rotation to reach a target position that does not include several revolutions, facilitates the control of the movement, since several revolutions do not have to be tracked.
- optical or haptic marking elements can support movement control.
- At least one thread turn of the coupling element has a housing thread section at its end facing the fluid connection, a section orthogonal to the longitudinal axis.
- the sealing element receiving guide structure When the sealing element receiving guide structure is moved into the orthogonal section, the sealing element receiving cannot be moved from this position by applying pure tensile or compressive forces in the direction of the longitudinal axis.
- the orthogonal section enables the positioning of the sealing element receptacle to be secured in this position, in particular in the position with a minimal distance from the fluid connection when the orthogonal section corresponds to this position.
- At least one thread turn of the coupling element has a housing thread section at its end facing the fluid connection a section which is set back to the longitudinal axis and which is set back with respect to the thread turn in the direction of the coupling side.
- the sealing element receiving guide structure When the sealing element receiving guide structure is moved into the recessed section, the sealing element receiving cannot be moved out of this position by applying pure rotary movements about the longitudinal axis, but must first, for example, by applying a compressive force to the Sealing element receptacle are moved along the longitudinal axis in the direction of the fluid connection from the recessed section.
- the positioning of the sealing element receiving guide structure in the recessed section preferably corresponds to a position of the sealing element receiving in the connected state.
- the recessed section can be provided as an alternative or in addition to the orthogonal section. In the case of a combination of the recessed and orthogonal section, the recessed section preferably adjoins the orthogonal section in the guiding direction of the sealing element receiving guide structure at an end of the thread facing the fluid connection.
- the sealing element receiving guide structure is first moved along the at least one thread turn having a pitch in the direction of the fluid connection, then reaches the orthogonal section and can then be moved into the recessed section by a continued rotary movement
- the housing section can be rotated relative to the longitudinal axis.
- the sealing element receptacle can thus be moved along the longitudinal axis via the sealing element receptacle guide structure by means of a rotary movement of the housing section about the longitudinal axis.
- the housing section is preferably a section that is rotatably mounted with respect to the rest of the housing, so that the rotary movement carried out by the housing section is not transmitted to the rest of the housing. This facilitates handling or connection and disconnection, in particular if, for example, further components are already connected to the fluid connection.
- the sealing element receptacle can be rotated relative to the longitudinal axis and / or to the coupling element housing.
- the sealing element receptacle is mounted in the coupling element housing via an elastic element, in particular a compression spring element, which acts in the direction of the longitudinal axis and is arranged between the fluid connection and the sealing element receptacle.
- the sealing element receptacle can be pretensioned in the direction of the coupling side via the elastic element, so that the risk of unintentional movement of the sealing element receptacle in the direction of the fluid connection and thus an unintentional release of the fluid opening is further reduced.
- the preload can be used to automatically move the sealing element receptacle from a sealing element receptacle position at a minimum distance from the fluid connection back into a sealing element receptacle position at a maximum distance from the fluid connection in order to seal the fluid opening again via the sealing element.
- the elastic element can be designed as a compression spring, that is to say, for example, as a spiral spring, which is arranged between the sealing element receptacle and the fluid connection.
- the elastic element can also be formed by the sealing element receptacle itself or the sealing element.
- the sealing element receptacle guide section can already be inserted into the coupling element housing thread section in the disconnected state.
- the coupling element housing can have a structure which correspondingly interacts with the sealing element receptacle.
- the mating coupling element housing has at least one mating coupling element guide structure section which comprises the mating coupling element guide structure and is designed such that it can be inserted into a sealing element receiving groove, as described for the coupling element.
- the counter-coupling element guide structure section can be designed, for example, as an end section facing the counter-coupling side, which has at least one radial projection opposite the section of the counter-coupling element adjoining in the direction of the counter-coupling element fluid connection.
- the height of the radial projection in the longitudinal direction corresponds to the height of the mating coupling element guide structure or forms it.
- the radial projection together with the rest of the mating coupling element guide structure section can form a ring protruding in the longitudinal direction over the mating coupling element sealing element for engagement in the sealing element receiving groove of the coupling element, which can further seal the connection of the mating coupling element sealing element and the sealing element of the coupling element in the radial direction.

- Fig. 1 shows a cross-sectional view of a coupling element 100 in a plane parallel to the longitudinal axis L1 of a coupling element housing 10 of the coupling element 100 in an exemplary first embodiment.
- the cutting line corresponds to the cutting line AA of the coupling system 300 shown in FIG. 6.
- the longitudinal axis L1 of the coupling element 100 runs from a fluid connection 12 in the direction of a coupling side 13 Mandrel 30, which is designed as a fluid channel, a sealing element receptacle 20 with a sealing element receptacle guide structure 22, a sealing element 23 received in the sealing element receptacle 20 and an elastic element 40 which is arranged between an end of the coupling element housing 10 on the fluid connection side and the sealing element receptacle 20.
- the coupling element housing 10 has a housing section 10a which extends from the section of the coupling element housing 10 on the fluid connection side in the direction of the coupling side 13 around the longitudinal axis L1.
- the housing section 10a is preferably mounted rotatably about the longitudinal axis L1.
- the housing section 10a also comprises a coupling element housing thread section 10b with two threads 10c, although more or fewer threads 10c can also be provided.
- the threads 10c are each formed here as grooves running helically from the coupling side 13 in the direction of the fluid connection 12 over an angle of 180 °.
- a coupling-side end of one thread turn 10c lies opposite a coupling-side end of the other thread turn 10c in relation to the longitudinal axis L1.
- the respective fluid connection-side ends of the thread turns 10c also lie opposite one another in relation to the longitudinal axis L1.
- the sealing element receptacle 20 In the disconnected state shown, the sealing element receptacle 20 is in a position at a maximum distance from the fluid connection 12 and is held in the coupling element housing 10 via two sealing element receptacle guide structures 22, which each engage in one of the threads 10c.
- the sealing element receiving guide structures 22 to be provided primarily serve for the guided movement of the sealing element receiving 20 along the longitudinal axis L1 from a position of the sealing element receiving 20 from a position with a maximum distance from the fluid connection 12 to a position with a minimum distance from the fluid connection 12 and vice versa.
- the sealing element 20 can also be held in the coupling element housing 10 by other structural designs and the respective sealing element receiving guide structures 22 only fully engage with the respective thread turns 10c when the sealing element receiving element 20 moves along the longitudinal axis L1 in the direction of the fluid connection 12.
- the thread 10c in the direction of the longitudinal axis L1 is greater than the length of the sealing element receiving guide structure 22 in this direction, that is, the height / length H1 of the thread 10c in the direction of the longitudinal axis L1 is greater than the height / Length H2 of the sealing element receiving guide structure 22 in this direction.
- the height / length H1 of the thread is constant here in order to create a surface pressure between the mutually facing surfaces of the sealing element 23 and one which will be described later
- the sealing element receiving guide structure can thus be moved in the thread 10c in the direction of the longitudinal axis L1.
- the extension of the thread 10c in The direction of the longitudinal axis in connection with the extension of the sealing element receiving guide structure in this direction should be selected so that the sealing element 23 still seals the fluid opening 31 of the mandrel 30 in the state shown, even if the sealing element receiving guide structure is located on the delimitation of the thread facing the fluid connection 12 10c is present.
- the sealing element 23 is accordingly arranged and dimensioned in the sealing element receptacle 20 such that, in a disconnected state, it completely surrounds, i.e. seals, a fluid opening 31 arranged in an end section of the mandrel 30 facing the coupling side 13.
- the coupling element 100 also includes an elastic element 40, which is formed here from a compression spring.
- the elastic element 40 is arranged in the coupling element housing 10 and is supported against a housing section on the fluid connection side and the sealing element receptacle 20.
- the sealing element receptacle 20 is pretensioned in the direction of the coupling side 13 so that it rests with the sealing element receptacle guide structure 22 on the side of the thread 10c facing away from the fluid connection 12 and is held in this position under pretension.
- the sealing element receptacle 20 also has a sealing element receptacle groove 21 which is set back from the end face 20a of the sealing element receptacle 20 in the direction of the longitudinal axis L1 towards the fluid connection 12.
- the sealing element receiving groove 22 extends annularly around the longitudinal axis L1 and is delimited in the radial direction by the inner wall of the coupling element housing 10.
- the movement of the sealing element receptacle 20 from a position with a maximum distance from the fluid connection 12 in the direction of a position with a minimum distance from the fluid connection 12 or vice versa takes place via the guidance of the respective sealing element receptacle guide structures 22 in the respective threads 10c in the direction of the fluid connection 12 or in the opposite direction depending on the direction of movement to be provided.
- the housing section 10a and / or the sealing element receptacle 20 can be set in a rotational movement in a targeted manner. This corresponds to a targeted screwing in or unscrewing.
- the application of a compressive or tensile force depending on the intended direction of movement will be sufficient if the housing section 10a and / or the sealing element receptacle 20 are rotatably mounted in such a way that the housing section 10a and / or the sealing element receptacle 20 independently screws in or out.
- FIGS. 2 and 3 show a section of an end of a fluid connection-side thread 10c with a top view in the direction of view of the longitudinal axis L1.
- the filled-in arrow represents a longitudinal axis direction in the direction of the coupling side 13, while the unfilled arrow represents a longitudinal axis direction in the direction of the fluid connection 12.
- FIG. 2 illustrates an exemplary end of a fluid connection-side thread 10c with a section 10d that is orthogonal to the longitudinal axis L1. If a sealing element receiving guide structure 22 is moved into the orthogonal section 10d, an applied compressive or tensile force does not cause any rotary movement of the housing section 10a and / or the sealing element receiving 20. The risk of unintentional movement is accordingly reduced.
- FIG. 3 shows an exemplary end of a fluid connection-side thread 10c with a section 10e set back in the direction of the filled-in arrow.
- the position of the sealing element receptacle 20 at a minimal distance from the fluid connection 12 is formed by the position of the transition between the section of the thread 10c, which is still inclined, and the recessed section 10e.
- the position of the sealing element receptacle 20 when the sealing element guide structure 22 engages in the offset section 10e is understood as a position with a minimal distance from the fluid connection 12.
- the sealing element receiving guide structure 22 must first be moved again relatively in the direction of the fluid connection 12 in order to be able to overcome the recessed section 10e.
- This form of securing the position is also supported by the provision of the elastic element 40.
- the position securing according to FIG. 3 does not exclude a position securing according to FIG. 2, so that combined position securing can also be used.

- the respective longitudinal axes L1 and L2 are not shown here. Reference is made to FIGS. 1 and 4 in this regard.
- the sealing element receptacle 20 By introducing the mating coupling element 200 into the coupling element 100, the sealing element receptacle 20 according to FIG. 5 is initially moved from its disconnected state with a sealing element receiving position at a maximum distance from the fluid connection 12 into a position in which the sealing element receiving guide structures 22 on the boundary facing the fluid connection 12 of the thread 10c is applied. This corresponds to a position of the mating coupling element 200 in which the mating coupling element guide structures 53 rest against the sealing element receiving guide structures 22 and can be moved together with them into the thread 10c.
- the common guidance of the mating coupling element guide structures 53 and the sealing element receiving guide structures 22 in the thread 10c takes place by a relative rotation between the mating coupling element 200 and the coupling element 100 according to a screwing in or unscrewing process.
- the application of a compressive or tensile force depending on the intended direction of movement may be sufficient if the housing section 10a and / or the sealing element receptacle 20 are rotatably mounted in such a way that the housing section 10a and / or the Sealing element holder 20 screwed in or out independently. Due to the positive fit between the mating coupling element guide structures 53 and the sealing element receiving guide structures 22 in connection with the thread 10c, the mutually facing surfaces of the mating coupling element sealing element 60 and the sealing element 23 are guided along the thread 10c in a fixed position. The positionally fixed relationship can correspond to a minimum surface pressure that can be further supported by the spring force of the elastic element 40.
- FIG. 6 shows a schematic cross-sectional view of a coupling system 300 according to FIG. 5 in a plane parallel to the longitudinal axis L1 or the counter-coupling element longitudinal axis L2 in the connected state.
- the respective longitudinal axes L1 and L2 are not shown and reference is made again to FIGS. 1 and 4.
- the movement of the mating coupling element 200 in the coupling element 100 in the direction of the fluid connection 12 up to the fluid connection-side end of the threads 10c and thus the movement of the sealing element receptacle 20 on the fluid connection-side end of the threads 10c takes place here, for example, by rotating the mating coupling element 200 or by moving the mating coupling element 200 of the Coupling element 100 when the housing section 10a and / or the sealing element receptacle 20 are rotatably mounted in such a way as described above.
- the sealing element receptacle 20 When the mating coupling element guide structures 53 and the sealing element receiving guide structures 22 have reached the end of the threads 10c on the fluid connection side, the sealing element receptacle 20 is thus in a sealing element receptacle position at a minimal distance from the fluid connection 12. This position corresponds to a connected state in which the fluid opening 31 is via the Counter-coupling element fluid connection 51 facing side of counter-coupling element sealing element 60 protrudes into fluid channel 60 and thus forms a fluid connection.
- FIG. 7 additionally shows an overview of all external views of the coupling system 300 according to FIGS. 4 and 5, the sectional views along the section line A-A and section line B-B and a perspective view in the disconnected state.
- FIG. 8 shows an overview of the coupling system 300 according to FIG. 7 in a state in which the mating coupling element has been inserted into the coupling element and FIG. 9 in a connected state.
- FIGS. 10 to 12 show corresponding overviews of a coupling system 300 ′ according to a second embodiment in a disconnected state (FIG. 10), a state in which the mating coupling element has been inserted into the coupling element (FIG. 11) and a connected state (FIG. 12).
- the coupling system 300 ' according to the second embodiment comprises a coupling element 100' and a mating coupling element 200 ' .
- the coupling system 300 'of the second embodiment differs primarily from the coupling system 300 of the first embodiment by the counter-coupling element 200 ' and the design of the coupling element 100 ' that corresponds to this.
- the mating coupling element 200 ′ has a mating coupling element guide structure section 54 ′ which has two mating coupling element guide structures 53 ′ that are shortened in the direction of the longitudinal axis L2 compared to the mating coupling element guide structures 53 of the first embodiment.
- the thread 10c of the coupling element 100 ' is thus also shorter in the direction of the longitudinal axis L1 than that of the coupling element 100.
- a guided movement of the Counter-coupling element guide structures 53 ' and thus a movement of the sealing element receptacle 20 of the coupling element 100, which then releases the fluid opening 31 of the mandrel 30, can thus be delayed until the sealing element receptacle 20 is reliably radially sealed by the counter-coupling element guide structure section 54.
- a corresponding securing can alternatively or additionally also be achieved in that the mating coupling element guide structures 53 or 53 'are not provided directly on the end of the mating coupling element guide structure section 54 or 54 ' facing the mating coupling side 52, but rather begin set back in the direction of the mating coupling element fluid connection 51.
