(11) FIG. 7 shows a sectional view of the retention member, in a relaxed state of the ribbon of the retention member.

(12) FIG. 1 shows in a schematic embodiment a general scenario of a patient P being subjected for example to a gastro-intestinal feeding. A catheter 2 is placed on the patient P, entering into the patient P through an access 20, wherein the catheter 2 is secured to the patient P close to the access 20 by means of a retention member 1 in order to avoid, for example, an accidental removal or displacement of the catheter 2.

(13) An embodiment of a retention member 1 is shown in FIG. 2 to 5A, 5B.

(14) The retention member 1 comprises a base element 10 having a generally triangular shape with three tips and three legs extending in between the tips of substantially equal length. The retention member 10 has a top side 104 for receiving the catheter 2 and a bottom side 103 to be placed on the skin of a patient P.

(15) The retention member 1 comprises a ribbon 14 connected, at a first end 140, to the top side 104 of the base element 10 and having a second end 141 opposite the first end 140. The ribbon 14 extends from the base element 10 and can be inserted through openings 150, 151 formed in the base element 10 in order to secure the catheter 2 on the retention member 1, as it is illustrated in FIG. 3.

(16) The openings 150, 151 are formed by slits in the base element 10, wherein the slits are terminated at both ends by end holes 150A, 151A extending from the top side 104 through to the bottom side 103 of the base element 10. The ribbon 14 can be inserted through the slits 150, 151 (leading to an elastic deformation of the base element 10 in the area of the slits 150, 151). The end holes 150A, 151A ensure that the base element 10 is not torn open in the area of the slits 150, 151 when using the retention member 1.

(17) The base element 10, at its top side 104, comprises a groove 11 extending along a middle line of the base element 10 from a leg 100 in between a first end a second tip of the triangular base element 10 towards a third tip 101 of the base element 10, as it is visible in FIG. 2. The groove 11 is formed into the top side 104 of the base element 10 and passes by the ribbon 14, such that by inserting the ribbon 14 with its second end 141 through the openings 150, 151 a loophole is formed through which the catheter 2 may extend for securing it to the retention member 10 (see the sectional views of FIGS. 4B, 4C and 5A, 5B).

(18) At the third tip 101 a guide hole 13 is formed having a cross-sectional shape of a cross. The guide hole 13 reaches from the top side 104 of the base element 10 towards the bottom side 103 and allows to insert the catheter 2 such that the catheter 2 extends along the groove 11 on the top side 104 and reaches through the guide hole 13 to pass from the top side 104 to the bottom side 104 of the base element 10.

(19) The guide hole 13, as said, is arranged at the third tip 101 of the base element 10. The region of the guide hole 13 herein is separated from the region of the base element 10 in which the ribbon 14 is placed by means of a wall section 12 protruding from the top side 104 of the base element 10, the wall section 12 extending transversely with respect to the middle line, i.e., transversely to the groove 11 formed on the top side 104 of the base element 10. The wall section 12 provides for a stiffening across the base element 10 and allows for a bending of the tip 101 carrying the guide hole 13 about the wall section 12, the wall section 12 providing for a bending axis, as it is illustrated in FIG. 3.

(20) By inserting the catheter 2 through the guide hole 13 from the top side 104 of the base element 10 towards the bottom side 103 and by, at least to some extent, bending the base element 10 at the third tip 101, the catheter 2, at the tip 101, is (slightly) bent and pretensioned towards the skin of the patient P such that it is pressed against the skin and assumes a defined, secure position on the skin of the patient P.

(21) For securing the catheter 2 on the retention member 1, the ribbon 14, with its second end 141, is inserted through the openings 150, 151 formed in the base element 10. Herein it is possible to first place the catheter 2 on the base element 10 and to insert the ribbon 14 through the openings 150, 151 after placing the catheter 2 on the base element 10. It however is also possible to first insert the ribbon 14 through the openings 150, 151 to form a loophole and to subsequently insert the catheter 2 through the loophole formed by the ribbon 14.

(22) As visible from the sectional views of FIGS. 4B and 4C, the ribbon 14, when inserted through the openings 150, 151, extends about a rib 153 formed in between the openings 150, 151. The ribbon 14 herein extends through a first opening 150 from the top side 104 of the base element 10 towards the bottom side 103, reaches around the rib 153 and extends back from the bottom side 103 towards the top side 104 through a second opening 151. By pulling on the second end 141 of the ribbon 14 in a pulling direction F1 as indicated in FIG. 4B, a catheter 2 extending through the loophole formed by the ribbon 14 can be fastened to the base element 10 such that it is securely held on the base element 10.

(23) As it is visible for example from FIG. 4A, a bottom side 152 of the rib 153 is recessed with respect to the bottom side 103 of the base element 10. This allows to place the ribbon 14 around the rib 153, as it is shown in FIG. 4B, without the ribbon 14 protruding beyond the bottom side 103 of the base element 10 when the ribbon 14 is inserted through the openings 150, 151.

(24) To stiffen the base element 10 in the region of the rib 153, an elevation 15 is formed within the region of the rib 153, the elevation 15 protruding from the top side 104 of the base element 10.

(25) When the ribbon 14 is inserted through the openings 150, 151 and when the ribbon 14 is tightened by pulling on the second end 141 to securely fasten a catheter 2 on the base element 10, the ribbon 14 is held in place by compressional forces acting in between the ribbon 14 and the base element 10 within the openings 150, 151 such that the ribbon 14 is frictionally retained within its inserted position.

(26) For releasing the catheter 2, a user may grab on a pulling handle 143 arranged on a section of the ribbon 14 in between the first end 140 and the second end 141. By pulling, in a pulling direction F2 (see FIG. 4C), on the pulling handle 143 the ribbon 14 can be pulled out of the openings 150, 151 such that the loophole formed by the ribbon 14 may be opened to remove the catheter 2 from the retention member 1. At the same time a user may press onto a tip 102 of the base element 10 closest to the rib 153 formed in between the openings 150, 151, such that a pulling force in the direction F2 may be exerted onto the ribbon 14 in an easy manner.

(27) The retention member 1 with the base element 10 and the ribbon 14 formed thereon is integrally formed in one piece for example from silicone rubber. The retention member 1 is easy and intuitive to handle and at the same time is easy and cost-efficient to manufacture.

(28) In addition, the retention member 1 may be, as illustrated in FIGS. 5A and 5B, used in connection with catheters 2 of different diameters, without having to modify the retention member 1. In particular, by placing a catheter 2 of a particular diameter on the base element 10 of the retention member 1 and by suitably pulling on the second end 141 of the ribbon 14 until the catheter 2 is securely fastened to the base element 10, a catheter 2 of any (conventionally used) diameter may be fastened to the retention member 1 without having to structurally modify the retention member 1.

(29) FIGS. 6 and 7 show another embodiment of a retention member 1 having a base element 10 and a ribbon 14 connected thereto.

(30) The embodiment of FIGS. 6 and 7 differs from the previously described embodiment in the shape of the guide hole 13, the shape of the pulling handle 143 attached to the ribbon 14 and furthermore in the shape of the opening 151 extending through the base element 10. Furthermore, the embodiment of FIGS. 6 and 7 does not comprise a wall 12 protruding from the base element 10 to structurally separate the area of the guide hole 13 from the area of the base element 10 to which the ribbon 14 is attached.

(31) In the embodiment of FIGS. 6 and 7, the guide hole 13 has a triangular shape.

(32) Analogously as depicted in FIG. 3 a catheter 2 may be inserted through the guide hole 13 to extend along a groove 11 on the top side 104 of the base element 10 through the guide hole 13 towards the bottom side 103 of the base element 10. This allows for a guiding of the catheter 2 and a pretensioning of the catheter 2 towards the patient's skin.

(33) The pulling handle 143 in the embodiment of FIGS. 6 and 7 points towards the other side as compared to the embodiment of FIG. 2 to 5A, 5B. Just as well the pulling handle 143 allows a user to pull on the ribbon 14 in order to release the ribbon 14 with its and 141 from the base element 10.

(34) As visible in the sectional view of FIG. 7, the opening 151 extends through the base element 10 at a tilted angle. Again, as in the embodiment of FIG. 2 to 5A, 5B, the ribbon 14 with its end 141 may be inserted through the openings 150, 151 formed by slits in the base element 10 and terminated by end holes 150A, 151A such that, in a closed state analogously to FIG. 4B, a loophole is formed to fasten the catheter 2 on the base element 10.

(35) Other than that the embodiment of FIGS. 6 and 7 resembles the embodiment of FIG. 2 to 5A, 5B, such that it also shall be referred to the detailed description above.

(36) The idea underlying the invention is not limited to the embodiments described above, but may be implemented in an entirely different manner.

(37) A retention member of the kind described herein may be employed for different purposes, for example for the medication, hydration or feeding of a patient. The gastro-intestinal feeding of a patient in this regard is only one example of a possible use of a retention member as described herein.

(38) The retention member may have a different shape and structure than described herein. For example, the retention member may be made out of a different material than silicone rubber. In addition, the retention member may have a shape different than a triangular shape, for example a quadratic or rectangular shape.
