DETAILED DESCRIPTION

[0045] FIG. 1 shows a perspective view of an anchoring device 2 according to the disclosure in an opened state, in which a cover 4 is in an opened position relative to a base 6.

[0046] The base 6 has a base plate 8, from the top of which three pins 10, 12 and 14 extend upward. The base plate 8 has the outline of a rounded rhombus. The three pins 10, 12 and 14 are arranged in a triangle. The middle pin 10 is arranged at one corner of the rhombus-shaped base plate 8 and the two other or respectively outer pins 12 and 14 are arranged at the two sides of the rhombus-shaped base plate 8 adjacent to the corner of the middle pin 10.

[0047] A hollow-cylindrical projection 16 extends downward from the underside of the base plate 8 and is configured concentrically with the base plate 8. Two semi-circular cylindrical recesses 18 are configured in the base plate 8, whose planar sides are arranged parallel to each other such that their round sides lie in a common circular-cylindrical surface. A strut 20 is configured in the base plate 8 between the recesses 18. The common circular-cylindrical surface of the recesses 18 is concentric to a circular-cylindrical space defined by the hollow-cylindrical projection 16. The two recesses 18 penetrate the base plate 8 so that the recesses 18 are connected to the circular-cylindrical space defined by the hollow-cylindrical projection 16. The circular-cylindrical space defined by the hollow-cylindrical projection 16 forms a sensor accommodation 22, the top of which is partially accessible from above due to the recesses 18. The strut 20 forms a stop for a sensor (not shown) received in the sensor accommodation 22 and/or provides a stiffening (strength increase) of the base 6 or of the base plate 8, respectively.

[0048] At each of the two acute-angled corners of the rhombus-shaped base plate 8, a circular-cylindrical fixing recess 24 is configured that is oriented perpendicular to the plane of extension of the base plate 8 or, respectively, runs parallel to the projection 16. The fixing recesses 24 are configured to be able to fix the anchoring device 2, for example, via screws or clips (not shown) to a housing of a medical device or to a fixation bandage of a person to be treated or monitored.

[0049] At one of the two acute-angled corners of the rhombus-shaped base plate 8, a bow-shaped projection 26 is provided, which is configured in such a way that an identification tape or a security seal for the anchoring device 2 can be attached to the projection 26. Alternatively or additionally, the bow-shaped projection 26 may be arranged and/or configured such that a (new or further) anchoring point for the line 64 to the anchoring device 2 and/or an anchoring point for the anchoring device 2 to a medical device may be created at the bow-shaped projection 26 with a cable tie or the like.

[0050] At the obtuse-angled corner of the rhombus-shaped base plate 8 at which the middle pin 12 is located, a cover hinge 28 is configured at a lower rim of the base plate 8.

[0051] The cover 4 is pivotably connected to the base 6 or to the base plate 8 via the cover hinge 28.

[0052] The cover 4 has a receptacle part 30 with a receptacle portion 32 and a second receptacle portion 34. The receptacle part 30 is connected to the cover hinge 28. A coupling portion 38 is pivotably connected to the receptacle part 30 via a coupling portion hinge 36.

[0053] The cover 4 is configured in the shape of a band, so that the receptacle part 30 corresponds essentially to a rectangular plate, on the two short sides of which on the one hand the cover hinge 28 and on the other hand the coupling portion hinge 36 are arranged.

[0054] The coupling portion 38 also corresponds substantially to a rectangular plate, which is connected to the receptacle part 30 on one side via the coupling portion hinge 36. At the two free corners of the rectangular plate-shaped coupling portion 38, coupling pins 40 and 42 are configured, which are oriented perpendicular to a plane of extension of the coupling portion 38, i.e.

[0055] upward in the opened position of the cover 4. The coupling pins 40 and 42 are configured to hold the cover 4 in position in the closed state and to prevent or complicate slipping of the cover 4 relative to the base 6 or to the base plate 8, respectively. The cover 4 cannot detach upward due to a flexible tongue 52 or a snap hook, respectively.

[0056] The outer pins 12 and 14 of the base 6 are configured such that they each have an outer surface or contact surface 44 or 46, which can come into surface contact with a corresponding outer surface or contact surface 48 or 50 of the corresponding coupling pin 40 or 42, respectively, when the cover 4 is in a closed position relative to the base 6 (see FIG. 5).

[0057] The flexible tongue 52 extends upward from the strut 20 of the base plate 8. The flexible tongue 52 is oriented substantially parallel to the pins 10, 12 and 14. The flexible tongue 52 and the pins 10, 12 and 14 are arranged in a rhombus in such a way that the flexible tongue 52 and the middle pin 10 are arranged at the obtuse-angled corners of the rhombus and the two outer pins 12 and 14 are arranged at the acute-angled corners of the rhombus. At the free end, the flexible tongue 52 has a wedge-shaped hook 54.

[0058] Between the middle pin 10 and the outer pin 12 or 14, the base plate 8 is configured in an arcuate shape, so that a gap 56 between the middle pin 10 and the outer pin 12 and a gap 58 between the middle pin 10 and the outer pin 14 together define an indentation 60 which is at least sectionally channel-shaped. Due to the arrangement of the pins 10, 12 and 14 in a triangle, the indentation 60, which is at least sectionally channel-shaped, is curvilinear or the indentation 60, which is at least sectionally channel-shaped, has a kink. The flexible tongue 52 is configured wider than the pins 10, 12 and/or 14, so that gaps 62 between the flexible tongue 52 and the respective outer pin 12 or 14 are smaller than the gap 56 or 58.

[0059] FIG. 2 shows a perspective view of a system according to the disclosure in a state in which the anchoring device 2 is open or the cover 4 is in the opened position relative to the base 6, and a line 64 is inserted into the indentation 60.

[0060] Due to the triangular arrangement of the pins 10, 12 and 14 or due to the curvilinear form of the indentation 60, the inserted line 64 is curved at a first site 66 or in a first portion, respectively. This curvature already ensures a certain self-locking effect, due to which sliding out of the line 64 out of the indentation 60 in the extension direction of the indentation 60 is prevented or made more difficult.

[0061] In the state shown in FIG. 2, the line 64 extends from the two spaces 56 and 58 or from the two ends of the indentation 60, respectively, in alignment with the two spaces 56 and 58.

[0062] In the state shown in FIG. 3, the line 64 is curved in a region adjacent to the gap 56 at a second site 68 or in a second portion, and in a region adjacent to the gap 58 at a third site 70 or in a third portion. Since the line 64 is curved not only at the first site 66, but additionally at the second site 68 and at the third site 70, the self-locking effect caused by the curvature only at the first site 66 can be supported. The curvatures at the second site 68 and at the third site 70 are opposite to the curvature at the first site 66 and are according to amount such that the portions of the line 64 adjacent to the second site 68 and at the third site 70 and projecting from the anchoring device 2 are collinear. In the state shown in FIG. 3, the line 64 is already curved at the three sites 66, 68 and 70. In particular, the anchoring device 2 is configured in such a way that the curvatures at the second and third sites 68 or 70, respectively, can be caused by closing the cover 4.

[0063] In order to curve the line 64 at the second site 68 and at the third site 70, receptacle portions 32 and 34 are provided on the receptacle part 30 of the cover 4.

[0064] FIG. 4 shows a perspective view of the system shown in FIG. 3 in a state in which the cover 4 of the anchoring device 2 is pivoted from the opened position toward the closed position. In the state shown in FIG. 4, the receptacle part 30 is pivoted to the base plate 8 such that the receptacle portion 32 ensures the curvature of the line 64 at the second site 68, the second receptacle portion 34 ensures the curvature of the line 64 at the third site 70, a portion 72 of the receptacle part 30, which is arranged between the receptacle portion 32 and the second receptacle portion 34 (see FIG. 1), abuts an outer side or surface of the middle pin 10, and the free end of the coupling portion 38 opposite the coupling portion hinge 36 rests on the wedge-shaped hook 54 of the flexible tongue 52.

[0065] If the cover 4 or the coupling portion 38 is pivoted from the position shown in FIG. 4 further in the direction of the base 6 (see arrow 74 in FIG. 4), the coupling pins 40 and 42 move toward the corresponding pins 12 and 14 of the base 6 and engage behind the pins 12 and 14 in such a way that pivoting of the receptacle part 34 away from the base 6 is prevented by interaction of the coupling pins 40 and 42 with the pins 12 and 14 of the base 6 or by interaction of the contact surfaces 48, 50 on the side of the cover 4 with the corresponding contact surfaces 44 and 46 on the side of the base 6. During the pivoting of the coupling portion 38 and the resulting engagement of the pins 12 and 14 by the coupling pins 40 and 42, an interaction of the free end of the coupling portion 38 with an inclined surface of the wedge-shaped hook 54 causes a deflection of the flexible tongue 52 in the direction away from the middle pin 10. When the coupling portion 38 is pivoted in such a way that the coupling pins 40 and 42 and the pins 12 and 14 are oriented parallel to each other and the contact surfaces 48 and 50 of the coupling pins 40 and 42 rest on the contact surfaces 44 and 46 of the pins 12 and 14, the flexible tongue 52 snaps shut in such a way that the wedge-shaped hook 54 engages form-fittingly around or behind the free end of the coupling portion 38. In this position of the coupling portion 38, the cover 4 is in the closed position, which is shown in FIG. 5.

[0066] In the state shown in FIG. 5, sliding out of the line 64 out of the indentation 60 in the direction transverse to the extension direction of the indentation 60 is prevented or made more difficult by the coupling portion 38, and in the direction of the extension direction of the indentation 60 is prevented or made more difficult by the self-locking effect caused by the indentation 60 and the receptacle portions 32 and 34.

[0067] In order to remove the line 64 of the anchoring device 2, the flexible tongue 52 has to be pivoted away from the coupling portion 38 (see arrow 76 in FIG. 5) in such a way that the hook 54 no longer interacts form-fittingly with the free end of the coupling portion 38 and the coupling portion 38 can be pivoted away from the base 6.

[0068] The anchoring device 2 according to FIGS. 1 to 5 is uniformly made of a thermoplastic material.
