Description

Non-releasable connector device

Description The invention relates to a connector device for establishing a fluid connection with another connector device.

A connector device of this kind comprises a connector member which is attachable to a connector member of another connector device and comprises a flow channel for guiding a fluid flow, and a fastening member arranged on the connector member for fastening the connector member to the connector member of the other connector device.

A connector device of this kind is in particular suited for medical applications in which two connection lines shall be connected to each other to pass a flow of a medical fluid, such as e.g. a medication, a nutritional solution for the enteral feeding or the like, from one line to the other.

A connector device of this kind may be used to connect two lines to each other. A connector device of this kind however may also be arranged for example on a reservoir container such as a flexible bag and may be used for connecting a line to the reservoir container.

Generally, a connector device of this kind shall allow for an easy connection. In particular, it should be easy and comfortable to establish the connection, but upon establishment of the connection it may be beneficial if the connection cannot be released without further ado, in particular not in an unintentional way.

In this regard it may be desirable to establish a connection which cannot be released at all anymore, at least when handling the connector device in an intended, prescribed manner. This may for example be beneficial if it shall be prevented that a user comes into contact with a medical solution guided through the connector device, for example cytostatics in oncology applications. EP 1 917 996 B1 discloses a Luer lock connector having a shank carrying a bush. Both on the shank and the bush a toothing is arranged for providing for an interaction between the shank and the bush. By rotating the bush in one direction the shank is carried along through interaction of the toothings of the bush and the shank. When the bush is rotated in the opposite direction, however, the toothings slide along each other such that the shank is not carried along. In this way the shank can be connected to another connector device for screwing the shank onto the other connector device by acting onto the bush, but the connection cannot be released because a counter-rotation of the shank is not possible by acting onto the bush. It is an object of the instant invention to provide a connector device, in particular for a Luer lock, which can be handled in an easy and comfortable manner and at the same time can be manufactured in an inexpensive way.

This object is achieved by means of a connector device comprising the features of claim 1 .

Accordingly, the connector device comprises an actuation member arranged movably on the fastening member and comprising a body and at least one interaction element formed spring elastic on the body, wherein the actuation member is constituted to interact with the fastening member to carry the fastening member along when the actuation member is moved in a first movement direction, but not to carry the fastening member along when the actuation member is moved in a second movement direction relative to the fastening member opposite to the first movement direction. The connector device can be connected to another connector device for example by screwing the connector device onto the other connector device. For this, a user may act onto the connector device by grabbing the actuation member arranged on the fastening member such that, by moving the actuation member in the first movement direction, the fastening member is carried along and in this way may be fastened to the other connector device. Because the actuation member interacts with the fastening member for carrying the fastening member along only when the actuation member is moved in the first movement direction, but does not interact with the fastening member for carrying the fastening member along when the actuation member is moved in the second movement direction, the connection may be established in a non-releasable fashion. In particular, the fastening member may be connected to the other connector device by establishing a screw connection, wherein an unscrewing of the fastening member is not possible because in unscrewing force may not be transmitted from the actuation member onto the fastening member. The actuation member comprises a body and at least one interaction element, for example one, two, three or even more interaction elements, arranged on the body. The interaction element herein is formed spring elastic on the body. For example, the body and the at least one interaction element may be formed integrally in one piece for example by using an injection molding technique such that an easy, inexpensive manufacturing of the actuation member becomes possible. Because the at least one interaction element is formed spring elastic, it may easily slide over the fastening member when moving the actuation member in the second movement direction, such that forces may be transferred from the actuation member towards the fastening member only when moving the actuation member in the first movement direction.

The actuation member may in particular be arranged rotatably on the fastening member. The actuation member hence can be rotated with respect to the actuation member, at least when moving the actuation member relative to the fastening member in the second movement direction. When moving the actuation member in the first movement direction, however, the fastening member is carried along such that in this way forces may be transferred from the actuation member to the fastening member for establishing a connection to another connector device.

The actuation member may have a generally cylindrical shape. In particular, the actuation member with its body may circumferentially extend about a cylindrical wall of the fastening member and may be movable with respect to the cylindrical wall of the fastening member. When the actuation member is moved in the first movement direction, the actuation member acts onto the fastening member for carrying the fastening member along in the first movement direction. When the actuation member however is moved in the second movement direction, the actuation member slides along the cylindrical wall without carrying the fastening member along.

The flow channel formed in the connector member, in one embodiment, is concentrical to the cylindrical wall of the fastening member. If the connector device for example is constituted as a male Luer lock connector, a conical insertion piece may be arranged concentrically within the cylindrical wall, such that the flow channel extending through the conical insertion piece of the male Luer lock connector may be connected to a female Luer lock connector by inserting the insertion piece into a corresponding opening of the female Luer lock connector, upon which the flow channel of the male Luer lock connector comes into fluid connection with a corresponding flow channel of the female Luer lock connector.

In one embodiment, the at least one interaction element is formed as a curved finger extending from the body along the first movement direction. The at least one interaction element in particular may be arranged on the inside of the (hollow) body and may extend from the body along the first movement direction. The at least one interaction element hence at one end is connected to the body and protrudes from the body with another end forming a stop portion to interact with the fastening member around which the actuation member extends. By forming the at least one interaction element as a curved finger, an elasticity is provided on the at least one interaction element in such a way that the fastening member is carried along when moving the actuation member in the first movement direction, but the actuation member easily slides over the fastening member when moving the actuation member in the second movement direction.

If the actuation member comprises multiple interaction elements, for example two, three or four interaction elements, such interaction elements are, according to another aspect, displaced with respect to each other along the first movement direction. If the actuation member is rotatable with respect to the fastening member, the interaction elements hence are distributed circumferentially on the inside of the body and may in particular be evenly spaced with respect to each other. In one embodiment, the fastening member comprises, for example on its cylindrical wall, at least one stop portion for interacting with the at least one interaction element of the actuation member. When the actuation member is moved in the first movement direction, the at least one interaction element of the actuation member comes into abutment with an associated stop portion of the fastening member such that the fastening member is carried along. When the actuation member however is moved in the second movement direction, the at least one interaction element slides over the at least one stop portion of the fastening member such that the fastening member is not carried along.

The at least one stop portion may for example be formed by a protrusion providing a stop face facing in a circumferential direction opposite the first movement direction of the actuation member. If the actuation member is moved in the first movement direction, hence, the at least one interaction element comes into abutment with the stop face and hence acts onto the fastening member for carrying the fastening member along.

In one embodiment, the fastening member, for example on its cylindrical wall, in particular on an inner face of the cylindrical wall, comprises a screw thread for connecting the connector device to the other connector device. The connector member hence may be connected to the other connector device by screwing the fastening member onto the other connector device. In a beneficial embodiment, the connector device is a male Luer lock connector having a conical insertion piece concentrical to a cylindrical wall. On an inner face inside of the cylindrical wall a screw thread is arranged, such that the male Luer lock connector may be connected to a female Luer lock connector by screwing the male Luer lock connector onto the female Luer lock connector. When establishing the connection, the insertion piece of the male Luer lock connector engages with a corresponding opening of the female Luer lock connector such that a fluid connection between the connectors is established.

The fastening member is arranged on the connector member, and the actuation member is movable, in particular rotatable, to the fastening member. Herein, different possibilities for connecting the fastening member to the connector member exist.

For example, in one embodiment the fastening member may be movably, for example rotatably, arranged on the connector member. The fastening member and the connector member hence form separate parts which can be moved with respect to each other. In this way, the fastening member can for example be screwed onto another connector device for connecting the connector member to the other connector device, without rotating the connector member. For the movable connection the fastening member may for example be rotatably arranged on a shaft portion of the connector member such that the fastening member can freely be rotated with respect to the connector member. In a different embodiment, the fastening member may be integrally formed with the connector member. In this embodiment the fastening member and the connector member form a single, integral piece, the fastening member hence not to being movable with respect to the connector member. Hence, when actuating the actuation member for moving the fastening member, also the connector member is moved, for example rotated.

According to another aspect, a locking element may be arranged on the fastening member or the actuation member for axially fixing the actuation member to the fastening member. By means of the locking element, for example in the shape of a locking ring arranged on a tip of the fastening member, the actuation member is secured on the fastening member, such that the actuation member can be moved with respect to the fastening member along a circumferential direction for actuating the fastening member, but cannot slip off the fastening member in an axial direction. The idea underlying the invention shall subsequently be described in more detail with reference to the embodiments shown in the drawings. Herein,

As schematically shown in Fig. 1 , two lines 10, 20, for example flexible PVC tubings, may be connected to each other by using connectors 1 , 2 for establishing a fluid connection in between the two lines 10, 20, in particular for passing a medical fluid from one line 10, 20 to the other line 20, 10.

The connectors 1 , 2 may in particular form a Luer lock connection, one of the connectors 1 , 2 having the shape and constitution of a male Luer lock connector, the other connector 2, 1 having the complementary shape of a female Luer lock connector.

Fig. 2 to 4 show an embodiment of a connector device 1 in the shape of a male Luer lock connector. The connector device 1 comprises a connector member 1 1 having, on one end, a conical insertion piece 1 1 1 which is insertable into a corresponding conical opening 21 1 of another connector device 2, as schematically shown in Fig. 4. Within the connector member 1 1 a channel 1 10 is formed to axially extend through the connector member 1 1 from a connection portion 1 15, to which a line 10 may be connected, towards and through the insertion piece 1 1 1 such that, by inserting the insertion piece 1 1 1 a fluid connection of the connector device 1 with the other connector device 2 having a corresponding channel 210 may be established.

In the embodiment shown in Fig. 2 to 4, a fastening member 13 is arranged on a shaft portion 1 18 of the connector member 1 1 , the fastening member 13 being integrally formed with the connector member 1 1 . The fastening member 13 comprises a cylindrical wall 1 13, the insertion piece 1 1 1 being arranged concentrically within the cylindrical wall 1 13 of the fastening member 13 and a screw thread 1 14 being formed on an inner circumferential face of the cylindrical wall 1 13 facing into an opening 1 12 surrounding the insertion piece 1 1 1 .

For attaching the connector member 1 1 to the other connector device 2, the screw thread 1 14 on the inside of the cylindrical wall 1 13 of the fastening member 13 is screwed onto a corresponding screw thread 214 on the outside of a connection piece 213 of the other connector device 2 such that a screw-type connection between the two connector devices 1 , 2 is established. When attaching the connector member 1 1 to the other connector device 2, the insertion piece 1 1 1 comes into engagement with the complementary opening 21 1 formed in the connection piece 213 of the other connector device 2. The actuation member 12 is arranged rotatably on the cylindrical wall 1 13 of the fastening member 13 and extends circumferentially about the cylindrical wall 1 13 such that the cylindrical wall 1 13 is enclosed by the actuation member 12. The actuation member 12 comprises a body 120 which is formed such that a user may grab the actuation member 12 to connect the connector device 1 to the other connector device 2.

Herein, the actuation member 12 provides for a non-releasable connection between the two connector devices 1 , 2. In particular, at the inside of the body 12, as shown in particular in Fig. 3A and 3B, three interaction elements 121 in the shape of curved fingers are arranged which are constituted to interact with the fastening member 13 for connecting the connector member 1 1 to the other connector device 2. The interaction elements 121 extend circumferentially about the cylindrical wall 1 13 and are formed spring elastic such that they may be elastically deformed with respect to the body 120 of the actuation member 12.

Each interaction element 121 at a first end 123 is connected to the body 120. At an outer end a stop portion 122 is formed for interacting with one of multiple stop portions 1 16 formed on the outside of the cylindrical wall 1 13 of the fastening member 13. The stop portions 1 16 of the fastening member 13 each have the shape of a protrusion having a stop face facing (opposite to a first movement direction V1 of the actuation member 12) towards the stop portion 122 of an associated interaction element 121 . Each interaction element 121 is in itself spring elastic and may be deformed, in particular by deflecting the stop portion 122 radially towards the outside. For this, the interaction element 121 is arranged at a gap with respect to the body 120 such that space is provided for deflecting the interaction element 121 towards the outside. When a user grabs the actuation member 12 and moves the actuation member 12 in a first movement direction V1 , the interaction elements 121 come into abutment with the stop portions 1 16 arranged outside on the cylindrical wall 1 13 of the fastening member 13. In this way, the fastening member 13 is carried along with the actuation member 12 such that the fastening member 13 can be screwed onto the connector member 21 of the other connector device 2.

If however the actuation member 12 is moved in an opposite, second movement direction V2, as indicated in Fig. 3A, the interaction elements 121 are elastically deformed and slide over the stop portions 1 16 formed on the outside of the cylindrical wall 1 13, such that the fastening member 13 is not carried along and hence may not be released from the other connector device 2 by rotating the actuation member 12.

Upon rotating the actuation member 12 in the second movement direction V2, the interaction elements 121 , with stop portions 122 formed at the outer ends of the interaction elements 121 , slide onto slopes 1 17 formed on the outside of the cylindrical wall 1 13 and hence are deflected radially towards the outside, such that the interaction elements 121 with their stop portions 122 slide over the stop portions 1 16 formed on the fastening member 13. In this way, it is prevented that a user may, in particular unintentionally, release the connector device 1 from the other connector device 2. Hence, it is prevented that a user may come into contact with fluids guided through the connector devices 1 , 2, in particular potentially hazardous fluids such as cytostatics.

By the deflection of the interaction elements 121 radially towards the outside the interaction elements 121 are elastically tensioned. When a stop portion 1 16 of the fastening member 13 is passed, each interaction element 121 snaps back into its original, non-deflected state (as shown in Fig. 3A). When the actuation member 12 is again moved in the first movement direction V1 , the interaction elements 121 hence may again interact with the stop portions 1 16 formed on the fastening member 13.

In the embodiment of Fig. 2 to 4, the actuation member 12 as well as the connector member 1 1 together with the fastening member 13 are each formed in one piece, for example by using an injection molding technique, from a plastic material. In particular, the interaction elements 121 are formed integrally with the body 120 of the actuation member 12, which allows for an easy and cost efficient production.

In the embodiment of Fig. 2 to 4 the connector member 1 1 and the fastening member 13 are integrally formed, the fastening member 13 hence fixedly being arranged on the connector member 1 1 . When arranging the connector member 1 1 on the other connector device 2 by rotating the fastening member 13, hence also the connector member 1 1 is rotated and carried along when actuating the actuation member 12.

In another embodiment shown in Fig. 5A, 5B the connector member 1 1 and the fastening member 13 are formed as separate pieces, the fastening member 13 being rotatably arranged on a shaft portion 1 18 of the connector member 1 1 . When screwing the fastening member 13 with its screw thread 1 14 on the inside of the cylindrical wall 1 13 onto the associated connector piece 213 of the other connector device 2, hence, the connector member 1 1 may remain stationary and in particular is not rotated together with the fastening member 1 1 .

As shown in the enlarged view of Fig. 5B, the fastening member 13 may for example be clipsed onto the shaft portion 1 18 of the connector member 1 1 , such that the fastening member 13 is axially fixed on the shaft portion 1 18, but is rotatable circumferentially about the shaft portion 1 18.

Other than the connector member 1 1 and the fastening member 13 being formed in two separate pieces the connector device 1 of the embodiment according to Fig. 5A and 5B is functionally identical to the embodiment described above according to Fig. 2 to 4, such that it shall be referred to the above.

As shown in an embodiment in Fig. 6 and 7, on a tip of the cylindrical wall 1 13 facing axially outward a locking element 14 in the shape of a locking ring may be arranged, the locking element 14 being fixedly connected to the fastening member 13 in order to axially fix the actuation member 12 on the fastening member 13. The actuation member

12 hence is axially held on the fastening member 13 such that it cannot slip off the fastening member 13.

Other than that the embodiment of Fig. 6 and 7 is functionally identical to the embodiment of Fig. 5A and 5B.

In another embodiment shown in Fig. 8 to 1 1 a connector device 1 comprises a connector member 1 1 having an insertion piece 1 1 1 to be inserted into a corresponding insertion opening 21 1 , similarly as it is shown in Fig. 4. The connector member 1 1 carries, on an end pointing away from the insertion piece 1 1 1 , a connection portion 1 15 for connecting a line to the connector member 1 1 such that the line is aligned with a channel 1 10 formed in and extending axially through the connector member 1 1 .

Arranged on the connector member 1 1 is a fastening member 13, the fastening member

13 circumferentially extending about the connector member 1 1 . The fastening member 13 is connected to and axially held on the connector member 1 1 by means of a clips connection, but is freely rotatable with respect to the connector member 1 1 along a circumferential direction.

The fastening member 13, on a first end associated with the insertion piece 1 1 1 of the connector member 1 1 , carries a cylindrical wall section 1 13 enclosing an opening 1 12. On an inner face facing the insertion piece 1 1 1 screw threads 1 14 are formed inside the cylindrical wall section 1 13 for connection to the connector piece 213 of the other connector device 2.

On a second end opposite the first end the fastening member 13 comprises a body portion 1 19 adjoining the portion of the fastening member 13 carrying the cylindrical wall section 1 13, wherein stop portions 1 16 are formed on the outside of the body portion 1 19, as visible from Fig. 1 1 , for interacting with an actuation member 12 extending circumferentially about the fastening member 13. The actuation member 12 is arranged on the fastening member 13 and interacts with the body portion 1 19 and the stop portions 1 16 arranged on the body portion 1 19. The actuation member 12 comprises a rotational body 120 and interaction elements 121 in the shape of elastic, curved fingers formed inside the body 120 to interact with the body portion 1 19 and the stop portions 1 16 arranged thereon when actuating the actuation member 12 in a rotational movement direction V1 , as indicated in Fig. 1 1 .

In particular, when actuating the actuation member 12 in the direction V1 , the interaction elements 121 interact with the stop portions 1 16 such that the fastening member 13 is carried along in the direction V1 and in this way may be screwed onto the connector piece 213 of the other connector device 2. When however rotating the actuation member 12 in the opposite movement direction V2 as indicated in Fig. 1 1 , the interaction elements 121 may slide over the stop portions 1 16 such that that no rotational force is transferred to the fastening member 13 and the fastening member 13 hence remains stationary on the connector member 1 1 . By actuating the actuation member 12 the fastening member 13 hence may be screwed onto the connector piece 213 of the other connector device 2, but may not be unscrewed. As visible from the sectional view of Fig. 9, the interaction elements 121 are formed inside the body 120 of the actuation member 12 only in the axial region of the body 120 being associated with the body portion 1 19 of the fastening member 13. No interaction elements 121 are formed in the region of the first, front end of the fastening member 13 carrying the cylindrical wall 1 13, as it is visible for example from Fig. 10.

In an embodiment shown in Fig. 12 and 13, a locking element 14 in the shape of a locking ring is additionally fixed to the front end of the actuation member 12 such that the actuation member 12 is axially secured on the fastening member 13 and may not slip of the fastening member 13. Other than that the embodiment of Fig. 12 and 13 is functionally identical to the embodiment of Fig. 8 to 1 1 , such that it shall also be referred to the above.

The idea underlying the invention is not limited to the embodiments described above, but may be implemented in an entirely different way. In particular, the invention may be applied to a Luer lock connector, and in this sense both to a male Luer lock connector and a female Luer lock connector. The invention however may in general be applicable to any type of connector.
