Definitions
- the invention relates to a connector for establishing a fluid connection between a first and a second fluid transmission component, with a connecting piece having an internal thread, with which a corresponding counterpart is screwed/can be screwed, and a cap sleeve which can be pushed over the connector and which, in a pushed-on state, cannot be detached from the Connection piece locked.
- infusion therapy it is known to use luer and luer lock fittings to connect fluid transmission components, such as infusion lines, extensions and branches, to each other and to the patient.
- fluid transmission components such as infusion lines, extensions and branches
- These connections are usually designed to be detachable.
- Such non-detachable connections must therefore be compatible with Luer connectors in order to be able to establish the connection, but must no longer be able to be detached (non-destructively) after the connection.
- a non-detachable connector for supply lines for intravenous infusions is known from EP 3 530 312 A1.
- the connector has a connecting piece and a cap sleeve, both of which have locking means that match one another the connecting piece and the union sleeve together and secure axially against each other. This prevents a relative movement between the cap sleeve and the connection piece in the axial direction.
- EP 3 081 253 A1 discloses a fitting with a connector body and a lock nut/cap sleeve.
- the connector body has a male luer lock for connecting the fitting to a mating connector.
- the connector body is also designed to be screwed to the lock nut in order to clamp a hose section that is slipped onto an end section of the connector body.
- Interlocking anti-rotation means are also provided on the connector body and the lock nut to prevent relative circumferential movement between the lock nut and the connector body when the hose is clamped. In this way, a non-destructively detachable connection can be guaranteed.
- EP 1 917 996 B1 also shows a non-reconnectable positive Luer-Lock connection piece for connection to all standard-compliant negative Luer-Lock connections.
- the connection piece has a toothing which is brought into engagement with a counter-toothing of a rotatably fitted cap sleeve when the cap sleeve is placed over the connection piece.
- the toothing and the counter-toothing are designed so that they interlock in a first direction of rotation for locking the Luer-Lock connection of the cap sleeve and slide freely against each other in a second direction of rotation opposite to the first direction of rotation.
- latching means are formed on the connecting piece and/or the cap sleeve for the non-detachable locking of the cap sleeve with the connecting piece.
- DE 202004 015 957 U1 discloses a sleeve with which a coupling, e.g. a Luer lock coupling, can be fixed and sealed between two connection parts.
- a coupling e.g. a Luer lock coupling
- the sleeve has molded parts which cover and stabilize the connecting parts after they have been coupled.
- the objects and goals of the invention are to eliminate or at least reduce the disadvantages of the prior art and in particular to provide a cap sleeve for a connector that is simple and inexpensive to produce and can be used universally, which prevents or prevents the loosening of a connection between two fluid transmission components .difficult.
- the objects and goals are achieved with regard to a generic connector according to the invention by the subject matter of claim 1.
- the invention is therefore based on the finding of using geometries of the connector components to secure the connector.
- the connector is accordingly configured/adapted according to the invention such that a latching means of the cap sleeve latches in the pushed-on state with an axial end face of the connecting piece facing the counterpart.
- a latching means of the cap sleeve latches in the pushed-on state with an axial end face of the connecting piece facing the counterpart.
- the connecting piece can have a sleeve part with the internal thread and a cone part accommodated in the sleeve part and connected to a hose section of the first fluid transmission component exhibit.
- the connecting piece can also be designed in one piece, ie the sleeve part and the cone part are designed as an integral/one-piece component.
- the cap sleeve can have partial circumferential projections in the axial direction/extension direction of the cap sleeve on an end section facing the counterpart, which in the pushed-on state engage with the connector, in particular with a connector handle.
- the connector handle can also have a circular-cylindrical main body, at least one first connection section branching off from the main body and being in fluid communication with the counterpart, and two handle sections protruding from an outer peripheral surface of the main body, between which the partial circumferential projections the cap sleeve are held in the pushed-on state of the cap sleeve.
- the connector handle has a further second connection section which branches off from the main body and can be coupled to the second fluid transmission component.
- a central axis of the first connection section is parallel to a central axis of the second connection section.
- the latching means of the cap sleeve can be pretensioned by the connector, in particular the connection piece, when the cap sleeve is pushed onto the connector.
- the coupling sleeve can have at least one elastic locking hook/tab protruding axially and radially inward from an inner peripheral surface of the coupling sleeve as a locking means.
- the cap sleeve has three locking hooks/tabs distributed evenly over the circumference.
- the cap sleeve can have at least one gripping element on its outer peripheral surface, which can be gripped by a user when the cap sleeve is pushed on.
- the at least one latching hook can have an axial latching section, which is designed to latch in the pushed-on state with the end face facing the counterpart, and a radial latching section, which is designed to engage behind or on an outer peripheral surface of the connecting piece in the pushed-on state this to be exhibit.
- the at least one latching hook can have the axial latching section and the radial latching section in order to fix the at least one latching hook in the axial direction or in the pushing-on direction and in the radial direction relative to the connection piece. It is thus possible to prevent at least one latching hook from sliding radially inwards in the event of a tensile load against the push-on direction on the end face of the connecting piece facing the counterpart, gripping into the connecting piece and shearing off in the process.
- the locking hooks/snap hooks can be mounted at one point inside the cap sleeve. There are no openings to the outside in the lateral surface of the cap sleeve.
- the locking hooks are arranged in such a way that they are self-locking under tensile load and do not slip over the connecting piece (nut) in order to prevent the cap sleeve from being dismantled.
- the locking hooks are provided with an additional lug (radial locking section) that rests on the connection piece. This prevents the snap-in hooks from slipping under the counterpart when subjected to a tensile load. Higher tensile forces can be absorbed and shearing off of the locking hooks can be counteracted.
- the at least one latching hook can be mounted at two points in the cap sleeve, with the cap sleeve for the at least one latching hook having at least two openings formed on the side of the latching hook, which allow elastic deflection of the at least one latching hook when it is pushed on or when the Ensure assembly of the union sleeve.
- the latching hooks can be mounted at two points inside the cap sleeve.
- the spring effect for deflecting the locking hooks during assembly of the cap sleeve takes place via Clearances/openings in the lateral surface of the cap sleeve.
- the locking hooks are also arranged here in such a way that they are self-locking under tensile stress and do not slip over the connection piece in order to prevent the cap sleeve from being dismantled.
- This variant also prevents the snap-in hooks from slipping under the counterpart when subjected to a tensile load. Higher tensile forces can be absorbed and shearing off of the locking hooks can be counteracted
- the invention relates to a cover for a large number of connector types, which can be slid over the connection of the connector and, when rusted, prevents the connection from coming loose.
- This is achieved by means of elastic locking means on the circumference of the inner surface of the cover, which snap into place on an end face of the connector when rusted and thus secure the cap sleeve against axial displacement on the connector.
- the overcoat has partial circumferential projections in the axial direction at one end, which interact with a handle on the connector attachment when the overcoat is rusted and largely prevent rotation of the overcoat around the connector.

- FIG. 3 is a perspective view of a cap sleeve according to the preferred embodiment
- FIG. 4 is a top view of the cap sleeve according to the preferred embodiment
- 5 is a perspective view of a cap sleeve according to a modification of the preferred embodiment
- FIG. 6 is a plan view of the cap sleeve according to the modification of the preferred embodiment
- FIG. 7 shows a sectional view of a connector according to a further preferred embodiment
- FIG. 8 shows a sectional view of a cap sleeve according to the further preferred embodiment.
- FIG. 9 is a sectional view of a connector according to a modification of the further preferred embodiment.
- the fluid transmission components can be, for example, an ampoule, a syringe or a hose or a hose section.
- the connector 1 is connected on the one hand to a hose section 2 as the first fluid transmission component, which in turn can be connected to a further fluid transmission component.
- the connector 1 has a connection section 3, which can be connected to the further fluid transmission component, in particular to a further hose section.
- the hose section 2 is accommodated in a cone part 4 of a connecting piece 5 of the connector 1 .
- the cone part 4 is designed essentially as a conical cylinder.
- a fluid opening 6 extends through the cone part 4 in the axial direction, with an outer diameter and an inner diameter of the cone part 4 decreasing from a side facing the hose section 2 to a side facing away from the hose section 2 .
- the cone part 4 On the end section facing the hose section 2 , the cone part 4 has an insertion section 7 with an inner diameter that is larger than that of the fluid opening 6 .
- the insertion section 7 is stepped outward from the fluid opening 6 by a step in the radial direction. If the hose section 2 is now pushed into the insertion section 7, this stage serves as an axial stop.
- the inner diameter of the insertion section 7 is smaller than an outer diameter of the hose section 2 in the preferred exemplary embodiment, so that the hose section 2 is held in the insertion section 7 .
- the insertion section 7 can also have an encircling nose or a protruding section which clamps the hose section 2 and thus holds it in the insertion section 7 .
- the tube section 2 can additionally or alternatively be glued into the insertion section 7, ie the tube section 2 and the insertion section 7 can be connected via an adhesive connection, in particular with a solvent-based adhesive.
- a first locking portion 8 and a second locking portion 9 are formed on an outer peripheral surface of a central portion of the cone part 4 .
- the first latching section 8 is in the form of a peripheral ramp with a ramp surface 8a facing the hose section 2 and a latching surface 8b oriented essentially perpendicular to the axial direction of the cone part 4 .
- the second latching section 9 is also in the form of a circumferential ramp, with its extensions being greater than those of the first latching section 8 both in the axial and in the radial direction. Ie a ramp surface 9a and a latching surface 9b of the second latching section 9 are larger than the ramp surface 8a and the latching surface 8b of the first latching section 8. In other words, the cross-sectional area defined by the second latching section 9 is larger than that of the first Latching section 8 defined cross-sectional area. Furthermore, a step 9c is formed on a ramp surface 9a of the second latching section 9
- a step 11 formed on an inner peripheral surface of a sleeve part 10 of the connecting piece 5 is supported on this step 9c.
- the sleeve part 10 is essentially in the form of a sleeve with a connecting section 12 facing the hose section 2 and a threaded section 13 facing away from the hose section 2 .
- the connecting section 12 tapers conically, i.e. with an outer diameter that decreases in the axial direction towards the hose section 2 .
- the threaded section 13 has an internal thread 14, in particular a Luer thread, with which a counterpart 15 described in more detail below is screwed.
- an end section of the connecting section 12 is designed with a smaller inner diameter than a maximum outer diameter of the first latching section 8. If the sleeve part 10 is now moved in the axial direction relative to the cone part 4 or pushed over the cone part 4 the end section of the connecting section 12 latches with the first latching section 8 and the step 11 of the connecting section 12 rests against the step 9c of the cone part 4, i.e. the cone part 4, in particular the connecting section 12, is between the first latching section 8 and the second latching section 9 held. The cone part 4 and the sleeve part 10 thus form the connection piece 5 .
- the threaded section 13 of the connection piece 5 is screwed to the counterpart 15 .
- the counterpart 15 has an external thread
- connection piece 5 is conical, so that when the counterpart 15 is screwed to the connection piece 5, the cone part 4 bears against the inner peripheral surface 17 in a fluid-tight manner in order to establish a fluid connection between the connection piece 5 and the counterpart 15.
- the counterpart 15 On an end section facing away from the connecting piece 5, the counterpart 15 also has a receiving opening 18, in which a connecting section 19a of a connector handle 20 is received.
- the connector handle 20 has, as shown in Fig. 2 to recognize a cylindrical main body 21 and the two connecting sections 19a, 19b arranged branching off from this. Ie fluid from the hose section 2 as the first fluid transmission component flows through the fluid opening 6 of the cone part 4 of the connection piece 5 into the counterpart 15 and from there via the connection section 19a into the cylindrical main body 21, where it finally flows via the connection section 3 into the at the connection section 3 connected, second fluid transmission component can flow.
- connection section 19b is essentially identical to that
- a check valve 37 is arranged in each of the connection sections 19a, 19b.
- connection sections 19a, 19b are arranged on the main body 21 in such a way that they branch off from it essentially perpendicularly. That is, a center axis of the terminal portion 19a and a center axis of the terminal portion 19b are im Substantially perpendicular to a central axis of the main body 21 .
- the central axis of the terminal portion 19a is parallel to the central axis of the terminal portion 19b, so that the terminal portions 19a, 19b branch off perpendicularly from the main body 21 at diametrically opposite locations of the main body 21 and offset in an axial direction thereof.
- the connector handle 20 has two handle portions 22 which extend in the axial direction of the main body 21 and protrude from the main body 21 at two diametrically opposite positions.
- the handle sections 22 each have a handle web 23 and a handle plate 24 .
- the grip webs 23 of the two grip sections 22 are each arranged in a plan view of the connector grip 20 in the circumferential direction between the connection sections 19a, 19b.
- the handle webs 23 are each offset by approximately 90° in the circumferential direction of the main body 21 with respect to the connection sections 19a, 19b.
- the grip plates 24 connect perpendicularly to the grip webs 23, so that the grip sections 22 in the plan view of the connector grip 20 essentially represent a T-profile.
- a plurality of ribs 26 are formed on a gripping surface 25 of the gripping plates 24 facing away from the main body 21, which ribs extend almost over the entire width of the gripping surface 25 and enable improved haptics and handling of the connector 1.
- the connector 1 also has a cap sleeve/overcoat 27 .
- the coupling sleeve 27 is pushed over the connector 1, i.e. the connection piece 5 and the counterpart 15, in order to make it difficult or to prevent access to the connector 1 in the connected/screwed state.
- the cap sleeve 27 serves as a safeguard against unintentional or accidental opening of the connector 1 .
- the cap sleeve 27 has a first sleeve portion 28 with a large diameter and a second sleeve portion 29 with a small diameter.
- the first sleeve section 28 and the second sleeve section 29 are connected to one another via a cone section 30 .
- In the cone section 30 three through openings 31 formed uniformly over the circumference are formed.
- the coupling sleeve 27 has three elastic latching hooks 32 distributed uniformly in the circumferential direction on an inner peripheral surface of the first sleeve section 28 (cf. FIG. 4). These are formed on the inner peripheral surface of a side of the first sleeve section 28 facing away from the second sleeve section 29 and protrude inwards from this into the cap sleeve 27, i.e. in the direction of the central axis of the cap sleeve 27 and in the direction of the second sleeve section 29.
- the latching hooks 32 are pressed/biased outwards by the connection piece 5 in the radial direction and slide along an outer peripheral surface of the connection piece 5.
- the latching hooks 32 snap inwards in the radial direction and thus latch with an end face of the connecting piece 5 facing the counterpart 15. It is therefore no longer possible to remove the cap sleeve 27 from the connector 1 without destroying it .
- the latching hooks 32 of the cap sleeve 27 latch with the end face of the connection piece 5, which permanently prevents access to the connector 1 without having to provide specific latching means on the connector 1.
- the cap sleeve 27 also has three rails/ribs 33 on the inner peripheral surface of the first sleeve section 28, which are formed uniformly over the circumference and in the circumferential direction between the latching hooks 32.
- the rails 33 are in contact with the connection piece 5, in particular with a support collar 34 formed on an outer peripheral surface of the connection piece 5, so that a relative movement between the connection piece 5 and the coupling sleeve 27 in the radial direction can be reduced.
- the two projections 35 are formed on an end face of the cap sleeve 27 facing away from the second sleeve section 29 and protrude from this end face in the axial direction.
- the projections 35 grip into the cavity formed between the gripping plates 24 when the cap sleeve 27 is in the pushed-on state.
- the projections 35 are held between the gripping plates 24 in the circumferential direction of the cap sleeve 27 when the cap sleeve 27 is in the pushed-on state, so that the cap sleeve 27 can no longer be rotated relative to the connecting piece 5 in the pushed-on state.
- the projections 35 which are in engagement with the connector handle 20, in particular the handle plates 24 of the handle sections 22, serve as anti-twist protection for the cap sleeve 27.
- Figs. 5 and 6 show the cap sleeve 27 according to a modification of the preferred embodiment.
- Two gripping elements 36 in the form of wings projecting from the outer peripheral surface are formed on an outer peripheral surface of the cap sleeve 27 .
- the rails 33 are no longer formed uniformly in the circumferential direction between the latching hooks 32, as can be seen in FIG. Rather, according to the modification of the preferred exemplary embodiment, four rails 33 are formed on the inner peripheral surface of the first sleeve section 28, with two rails 33 being arranged in the area of the partial peripheral projections 35 in each case.
- the cap sleeve 27 has two pairs of rails 33 such that the pairs of rails 33 are diametrically opposed to each other.
- connection piece 5 has a multi-part/multi-part design.
- the connecting piece 5 can also be formed from an integral/one-piece component.
- the cone part 4 and the sleeve part 10 can form the connecting piece 5 integrally.
- Figs. 7 and 8 show the connector 1 and the cap sleeve 27 according to a further preferred embodiment.
- the locking hooks 32 are each mounted or articulated at one point on an inner peripheral surface of the cap sleeve 27 and protrude radially inwards from this point into the cap sleeve 27 .
- a latching end section 38 of the latching hooks 32 i.e. an end section which latches with the connecting piece 5 when the coupling sleeve 27 is in the pushed-on state, has an axial latching section 39 and a radial latching section 40.
- the axial latching section 39 is designed to latch in the pushed-on state to the end face of the connecting piece 5 facing the counterpart 15 or to rest against it.
- the radial latching section 40 is designed to latch with an outer peripheral surface of the connection piece 5 in the pushed-on state, as can be seen in FIG. 7 .
- the radial latching section 40 is designed as an additional latching lug that protrudes from the respective latching hook 32 in the axial direction, i.e. in the direction towards the hose section 2, and which, when the cap sleeve 27 is in the pushed-on state, engages behind the outer peripheral surface of the connection piece 5 and thus the latching hook 32 in the radial direction relative to the connecting piece 5.
- the latching end section 38 of the latching hook 32 is essentially L-shaped with the axial latching section 39 and the radial latching section 40 .
- the axial latching section 39 latches in the pushed-on state of the cap sleeve 27 with the end face of the connecting piece 5 facing the counterpart 15
- the radial latching section 40 latches with the outer peripheral surface of the connecting piece 5 .
- the latching hooks 32 can be fixed in the radial direction relative to the connecting piece 5, which makes it possible to prevent the latching hooks 32 from moving away from the counterpart 15 (to the right in Fig.
- cap sleeve 27 or the latching hooks 32 of the cap sleeve consequently has a self-locking mechanism, so that a higher tensile load can be absorbed without the latching hooks 32 shearing off.
- FIG. 9 shows the connector 1 or the coupling sleeve 27 according to a modification of the further preferred exemplary embodiment.
- the latching hooks 32 are each mounted or articulated at two points on the inner peripheral surface of the cap sleeve 27 and protrude radially inwards into the cap sleeve 27 between these two points. In order to be able to deflect the latching hooks 32, as mentioned above, when the cap sleeve 27 is pushed over the connection piece 5, they must have a certain elasticity/spring effect.
- clearances/openings 41 are formed in a circumferential direction laterally next to the latching hooks 32 in a lateral surface of the cap sleeve 27 .
- the cap sleeve 27 has two openings 41 for each latching hook 32 extending through the cap sleeve 27 in order to ensure the spring effect of the latching hooks 32.
- the latching hooks 32 in the cap sleeve 27 have the axial latching section 39, which latches in the pushed-on state with the end face of the connecting piece 5 facing the counterpart 15, and the radial latching section 40, which in the pushed-on state at least partially rests against the outer peripheral surface of the cap sleeve 27 . It is thus also ensured in the case of the cap sleeve 27 according to the modification of the further preferred exemplary embodiment that the latching hooks 32 do not slide radially inwards into the threaded section 13 under the tensile load. This self-locking consequently prevents the locking hooks 32 from shearing off.
