Description

Technical Field

[0001] The present invention relates to a catheter introducer, a use of a catheter introducer, and a method of assembling a catheter introducer. Background Art

[0002] For example, conduit feeders for feeding cables through walls are known in the prior art. DE 10 2020126 444 A1 discloses a conduit feeder having a base and a plurality of conduit feeder modules.

[0003] A disadvantage of the catheter passers known in the prior art is that the assembly aid must be used separately and removed again after the insertion module is installed. When installed in the catheter passer, the insertion module is stabilized only by the vertical webs in the frame. Summary of the Invention

[0004] Therefore, the object of the present invention is to provide an improved catheter introducer, an improved use and an improved method. In particular, the object of the present invention is to provide a catheter introducer, a use and a method, wherein the insertion module can be flexibly inserted into the frame and has a higher stability in the assembled frame.

[0005] According to the invention, this object is achieved by a catheter introducer comprising at least one first frame part and at least one second frame part, wherein the first frame part comprises at least one base web and at least two vertical webs, wherein the second frame part can be arranged on the vertical webs to form at least one circumferential frame, wherein at least one assembly aid is arranged between the at least two vertical webs, wherein the at least one assembly aid is materially connected to the base web and has at least one predetermined breaking point.

[0006] Furthermore, according to the invention, the object is achieved by a conduit feeder as described above for feeding a cable through a wall.

[0007] Furthermore, according to the present invention, this object is achieved by a method for assembling the above-mentioned catheter introducer, the method comprising the following steps:

[0008] providing a first frame part, a second frame part and a plurality of plug-in modules,

[0009] inserting at least one insert module between two vertical webs of the first frame part or between a vertical web of the first frame part and an assembly aid or between two assembly aids of the first frame part, wherein at least one assembly aid is previously removed from the first frame part at a predetermined breaking point if the spacing between the vertical web and the assembly aid or between the two assembly aids is smaller than the nominal width of the insert module,

[0010] The second frame part is arranged on the vertical web of the first frame part.

[0011] The present invention provides a catheter introducer comprising at least one first frame component and at least one second frame component. The first frame component comprises at least one base web and at least two vertical webs, wherein the second frame component can be arranged on the vertical webs to form at least one circumferential frame. At least one assembly aid is arranged between the at least two vertical webs, wherein the at least one assembly aid is materially connected to the base web and has at least one predetermined breaking point.

[0012] As an advantage, the proposed conduit passer allows elongated components such as cables, pneumatic hoses, hydraulic hoses and / or optical waveguides to be introduced quickly, easily and, above all, in a space-saving manner into, for example, switch cabinets, housings or machines. Plug-in modules that are suitable for the elongated components to be passed through are particularly advantageous and can be inserted into the cable passer. The assembly aid can be removed or broken off from the first frame part at a predetermined breaking point. The assembly aid can be separated from the first frame part at a predetermined breaking point and removed in order to insert plug-in modules of different widths into the cable passer. The assembly aid is joined by material and is arranged on the base web in a manner that does not allow it to be lost. If necessary, the assembly aid can be easily and preferably separated from the first frame part or disconnected at a predetermined breaking point without tools. In addition, the assembly aid increases the stability of the assembled cable passer.

[0013] The exemplary list should not be regarded as an exhaustive list in the sense of the present invention, but may be supplemented within the scope of general technical knowledge.

[0014] The catheter introducer comprises a first frame component. The first frame component comprises a base web and at least two vertical webs. In one embodiment, the first frame component comprises more than two, preferably three or four vertical webs. The vertical webs are preferably arranged parallel to each other. Further preferably, the vertical webs are arranged on a first side of the base web. In one embodiment, the vertical webs are arranged just on the first side of the base web. Preferably, the vertical webs each comprise a receiver for a fastening element. Preferably, the second frame component can be fixed to the vertical webs by a fastening element. In addition, the fastening element is preferably designed as a screw, by which the second frame component can be screwed to the vertical webs.

[0015] In a further embodiment, the vertical webs include fastening holes. Preferably, the catheter passer can be secured to a wall, such as a wall of the device housing, using fastening elements such as screws or rivets. The fastening elements advantageously pass through the fastening holes to secure the catheter passer to the wall. The vertical webs are advantageously designed to form a complete circumferential frame together with the base web and the second frame member.

[0016] In a further embodiment, two or more than two, preferably three to five, more preferably more than five vertical webs are provided on the base web.The vertical webs advantageously support the second frame part.

[0017] The first frame part comprises at least one assembly aid. In one embodiment, it is provided that about one to about five assembly aids are provided. In one embodiment, it is provided that about one to about five assembly aids are provided between every two vertical webs.

[0018] If the term "approximately" is used in relation to a numerical value or a numerical range in the present invention, it should be understood that it is a tolerance range that is considered normal by those skilled in the art; specifically, the tolerance range is ±20%, preferably ±10%, and more preferably ±5%.

[0019] If different value ranges are specified in the present invention, for example a preferred value range and a further preferred value range, the lower limits and upper limits of the different value ranges can be combined with one another.

[0020] At least one assembly aid is fixed to the base web in a materially connected manner. "Materially connected" in the context of the present invention means that the assembly aid is connected to the base web in a material-to-material bonding manner. Preferably, the assembly aid and the base web are injection molded or cast in a single operation. The assembly aid can be made of the same material as the base web or a different material. Preferably, the assembly aid comprises the same material as the base web and is in particular molded in one piece. In a further embodiment, the assembly aid comprises a different material than the base web. In one embodiment, at least the first frame part is manufactured using a multi-component injection molding process.

[0021] The assembly aid preferably includes at least one guide section. Furthermore, each vertical web preferably includes at least one guide section. The guide section is preferably a section of the assembly device, used to guide and / or secure at least one insert during installation of the conduit feedthrough. Preferably, the insert module can be inserted into the first frame part between two guide sections. In one embodiment, at least one assembly aid is provided with a guide section directly adjacent to the base web. Advantageously, the guide section allows the insert module to be guided flush with the base web.

[0022] In one embodiment, at least one assembly aid has at least one plug for plugging with the second frame part on a side facing away from the base web. The at least one plug is designed, for example, as one or more pins, at least one tube or a conical section.

[0023] In one embodiment, the assembly aid does not have a plug. Further preferably, the assembly aid does not include a plug-in connection with the second frame part. In one embodiment, at least one assembly aid is spaced apart from the second frame part. This advantageously saves material. Furthermore, this has the advantage that the second frame part is easier to assemble onto the first frame part, as it is only necessary to insert the positioning elements of the second frame part into the receptacles of the vertical webs. This significantly speeds up the assembly of the cable guide.

[0024] The assembly aid comprises at least one predetermined breaking point. It is further advantageous if the assembly aid can be securely fastened to the first frame part in such a way that it cannot be lost. It is also very advantageous if the assembly aid can be at least partially removed from the first frame part without tools, which is necessary for assembling the first frame part with the plug-in module. In one embodiment, it is provided that the predetermined breaking point of the assembly aid has a material weakening. Preferably, the predetermined breaking point comprises a single-sided or double-sided notch or a material taper. In a further embodiment, the predetermined breaking point comprises a perforation. Advantageously, the assembly aid can be broken off from the first frame part at the predetermined breaking point. Further preferably, the assembly aid can be shortened at the predetermined breaking point.

[0025] For example, the assembly aids are arranged in the first frame part in such a way that a first spacing exists between a vertical web and an assembly aid and / or between two assembly aids. Advantageously, by removing the assembly aids, preferably without tools, a second spacing can be established between a vertical web and an assembly aid, between two vertical webs, or between two assembly aids, which second spacing is preferably approximately twice the first spacing. Further spacings can preferably be established by removing further assembly aids.

[0026] In one embodiment, the predetermined breaking points are arranged directly in the vicinity of the base web. After the assembly aid is removed at the predetermined breaking points, a break may remain in the web. The break is preferably located in the main plane of the first surface of the first side of the web. In a further embodiment, the predetermined breaking points are arranged on the assembly aid at a position spaced apart from the web. For example, at least one predetermined breaking point is arranged approximately in the center of the assembly aid. In one embodiment, the assembly aid comprises at least two predetermined breaking points. This allows the assembly aid to be shortened and / or completely removed as required, in particular without the use of tools.

[0027] The term “substantially” indicates a tolerance range that is acceptable to those skilled in the art from an economic and technical perspective, so that the corresponding features can still be recognized or implemented.

[0028] The catheter introducer comprises at least a second frame part. Advantageously, one or more inserts inserted into the first frame part can be fixed by means of the second frame part. The second frame part facilitates stable cable routing. Advantageously, the second frame part is arranged on the vertical web parallel to the first frame part. Furthermore, preferably, the second frame part is screwed to the vertical web. Preferably, a fastening element is provided for arranging the second frame part on the vertical web. The fastening element further preferably passes through a receiver of the second frame part so that the second frame part can be screwed to the first frame part, for example. In one embodiment, the second frame part comprises at least one plug receiver, in particular at least one plug for receiving at least one assembly aid.

[0029] In one embodiment, the second frame part has positioning elements, which are preferably assignable to the receivers of the vertical webs. The positioning elements are preferably assigned to the receivers of the fastening elements. The positioning elements can advantageously facilitate installation because they ensure that the receivers of the second frame part are aligned with the receivers of the vertical webs.

[0030] In one embodiment of the cable passer, it is assumed that the cable passer has multiple plug-in modules. It is more advantageous if the first frame member can be assembled with, for example, one to approximately ten plug-in modules. In one embodiment, the catheter passer is designed as a kit comprising at least a first frame member, a second frame member, and at least one plug-in module. The kit may include multiple plug-in modules, preferably one to approximately 20 plug-in modules. In one embodiment, the kit includes multiple plug-in modules that are particularly suitable for different applications. The kit preferably includes multiple plug-in modules, not all of which can be inserted into the first frame member at the same time. When assembling the first frame member with the plug-in modules, it is advantageous to be able to select from a variety of different plug-in modules to adapt the catheter passer to a specific application. At least one plug-in module is preferably made of a rubber-elastic material. Advantageously, at least one elongated member can be passed through an plug-in module. In one embodiment, it is assumed that each plug-in module has multiple elongated member receivers. In one embodiment, it is assumed that at least one plug-in module does not have an elongated member receiver. Advantageously, the plug-in module without an elongated member receiver can be used as a blind plug.

[0031] Insert modules of different widths can preferably be inserted into the first frame part. An insert module of a first width can preferably be inserted between two assembly aids, between an assembly aid and a vertical web, or between two vertical webs spaced apart from one another. Further preferably, an insert module of a second width can be inserted between two assembly aids, between an assembly aid and a vertical web, or between two vertical webs spaced apart from one another by a second distance.

[0032] Preferably, at least one insert module is inserted into the first frame part. Further preferably, the first frame part is assembled with a plurality of insert modules. Preferably, the first frame part is assembled or can be assembled with the insert modules such that the insert modules substantially completely fill the intermediate space between the base web and the second frame part.

[0033] An exemplary catheter introducer comprises a first frame part having a base web and three vertical webs arranged on a first side of the base web. Two assembly aids are arranged between the first vertical web and the second vertical web. A third assembly aid is arranged between the second vertical web and the third vertical web. The second frame part, which can be placed on the vertical webs, comprises receivers for fastening elements, which are formed as screws. The receivers are assigned positioning elements, which can be inserted into the receivers on the end faces of the vertical webs, respectively. The receivers of each vertical web each include an internal thread, into which the fastening elements can be screwed. The outer vertical webs, i.e. the first vertical web and the third vertical web, for example include fastening holes, through which the first frame part or the catheter introducer can be fixed to a wall, for example to a housing, by means of screws or rivets.

[0034] At least one assembly aid is materially connected to the base web. The assembly aid includes, for example, a guide section adjacent to the base web. Furthermore, the assembly aid includes, for example, a plug arranged on a side facing away from the base web. The plug of the assembly aid engages with a plug receptacle of the second frame part. Furthermore, the assembly aid includes a predetermined breaking point, for example, located directly on the base web. This predetermined breaking point is designed, for example, as a one-sided notch that weakens the material of the assembly aid in a defined manner, allowing the assembly aid to be removed from the first frame part without tools.

[0035] After assembling the second frame part onto the vertical bars of the first frame part, a circumferential frame is formed.

[0036] The predetermined breaking point, developed as an exemplary single-sided notch, is designed to meet the first side of the base web. The predetermined breaking point extends, for example, to approximately half the width of the mounting device so that the mounting device can be easily disassembled without tools.

[0037] The first frame part can be assembled with plug-in modules, which can be inserted between the vertical webs or assembly aids. The plug-in modules are developed for different elongated components. For example, some of the plug-in modules each include an elongated component receiver. Other elongated component receivers have diameters of different sizes. Some plug-in modules include two elongated component receivers. In addition, some plug-in modules include more than two, for example three or four, elongated component receivers. For example, some plug-in modules do not include any elongated component receivers or openings and can be used as blind plugs. The assembly aids simplify the precise positioning of the plug-in modules during assembly and, moreover, have the additional advantage of high stability during installation. For example, plug-in modules of different widths and / or heights can be inserted into the first frame part.

[0038] In a further exemplary embodiment of the cable guide, the assembly aid does not have a plug that engages with the second frame part. The assembly aid extends close to the second frame part but does not contact it even when the second frame part is assembled onto the first frame part. Specifically, the assembly aid is spaced apart from the second frame part. This embodiment eliminates the need to precisely screw the assembly aid into the plug-type socket of the second frame part, significantly simplifying assembly.

[0039] Furthermore, the invention also proposes the use of the conduit passer as described above to pass a cable through a wall. Specifically, the conduit passer can be used in conjunction with a variety of different insertion modules.

[0040] In addition, a method for assembling the catheter introducer is provided, comprising the following steps:

[0041] - providing a first frame part, a second frame part and a plurality of plug-in modules,

[0042] - inserting at least one insert module between two vertical webs of the first frame part or between a vertical web of the first frame part and an assembly aid or between two assembly aids of the first frame part, wherein at least one assembly aid is previously removed from the first frame part at a predetermined breaking point if the spacing between the vertical web and the assembly aid or the spacing between the two assembly aids is smaller than the nominal width of the insert module,

[0043] - Arrange the second frame part on the vertical web of the first frame part.

[0044] According to the invention, the spacing between two assembly aids is smaller than the nominal width of the insert module if the spacing is at least about 5%, preferably at least about 10%, more preferably at least about 25%, more preferably at least about 25% to about 90%, more preferably about 25% to about 75% smaller than the nominal width of the insert module.

[0045] In one embodiment, the nominal width of the insert module is about 1% to about 5% greater than the spacing between the vertical web and the assembly aid or the spacing between two assembly aids. The insert module is preferably used when the spacing between the vertical web and the assembly aid or between two assembly aids is prestressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Second frame member 32, which can be placed on vertical webs 13, 14, and 15, includes receivers 52, 54, and 56 for fastening elements 34, 36, and 38, which are formed as screws. Positioning elements 58, 60, and 62 correspond to receivers 52, 54, and 56, respectively, and can be inserted into receivers 40, 41, and 42 of vertical webs 13, 14, and 15. Receivers 40, 41, and 42 each include an invisible internal thread into which fastening elements 34, 36, and 38 can be screwed. Vertical webs 13 and 15 also include fastening holes 44, 46, 48, and 50, through which first frame member 11 or catheter introducer 10 can be secured to a wall, for example, using screws or rivets.

[0064] Figure 6An exploded view of a further embodiment of a catheter introducer is shown. Catheter introducer 10 comprises a first frame part 11 having a base web 12 and three vertical webs 13, 14, and 15 arranged on a first side 24 of base web 12. Two assembly aids 18 and 20 are arranged between vertical webs 13 and 14. A further assembly aid 22 is arranged between vertical webs 14 and 15. In contrast to the previous embodiment, assembly aids 18, 20, and 22 lack a plug that engages with second frame part 32.

[0065] Second frame member 32, which can be placed on vertical webs 13, 14, and 15, includes receivers 52, 54, and 56 for fastening elements 34, 36, and 38, which are formed as screws.

Vertical webs 13 and 15 also include fastening holes 44, 46, 48, and 50, through which first frame member 11 or catheter introducer 10 can be secured to a wall, for example, using screws or rivets.

[0066] Figure 7 Show Figure 6 Front view of the catheter introducer. The second frame part 32 is assembled on the vertical webs 13, 14 and 15 to form a circumferential frame 33. In addition, assembly aids 18, 20 and 22 are arranged between the vertical webs 13, 14 and 15. There is a spacing 64 between the vertical web 13 and the assembly aid 18. There is also a spacing 65 between the assembly aid 18 and the assembly aid 20, which is approximately the same size as the spacing 64. There is a spacing 68 between the assembly aid 20 and the vertical web 14, which is approximately the same size as the spacing 64. Since the spacings 64, 65 and 68 are approximately the same size, they are all referred to as the first spacing below. The assembly aids 18, 20 and 22 extend to a position close to the second frame part. In addition, the first frame part 11 includes fastening holes 44, 46, 48 and 50 arranged continuously in the vertical webs 13 and 15.

[0067] Figure 8 Show Figure 7 Even when the second frame part 32 is mounted on the first frame part, there is a spacing 29 between the assembly aid 18 and the second frame part 32. Due to this embodiment, the assembly aid does not need to be screwed precisely into the plug socket of the second frame part, which greatly simplifies assembly.

[0068] Figure 9 Show Figure 7The first frame part 11 of the catheter introducer 10 with the assembly aid 18 removed. The breaking point 19 on the base web 12 is formed essentially flat and does not interfere with, for example, Figure 10 Assembly of the insert module shown. By removing the assembly aid 18, the first spacing 64 of the insert element between the vertical web 13 and the assembly aid 18 has been increased to a second spacing 66 between the vertical web 13 and the assembly aid 14. The first spacing 68 between the assembly aid 20 and the vertical web 14 remains unchanged. Figure 9 In the embodiment shown in FIG. 1 , the assembly aid 22 is held between the vertical webs 14 and 15 .

[0069] The vertical webs 13, 14 and 15 comprise receivers 40, 41 and 42. Furthermore, the first frame part 11 comprises fastening holes 44, 46, 48 and 50 which are arranged in succession in the vertical webs 13 and 15.

In addition to insertion module 96, a further insertion module 98 having an elongated member receiver 132 is inserted into first frame member 11 between assembly aid 20 and vertical web 14. Catheter introducer 10 can be partially assembled. However, it is preferably fully assembled to prevent the insertion module from slipping off or to seal the housing of catheter introducer 10.

[0071] A further assembly aid 22 is provided between the vertical webs 14 and 15. The second frame part 32, which can be placed on the vertical webs 13, 14, and 15, includes receivers 52, 54, and 56 for the fastening elements 34, 36, and 38, which are designed as screws. Positioning elements 58, 60, and 62 correspond to the receivers 52, 54, and 56, respectively, and can be inserted into the receivers 40, 41, and 42 of the vertical webs 13, 14, and 15. The receivers 40, 41, and 42 each include an invisible internal thread into which the fastening elements 34, 36, and 38 can be screwed. The vertical webs 13 and 15 also include fastening holes 44, 46, 48, and 50, through which the first frame part 11 or the catheter introducer 10 can be fixed to the wall.

[0072] Advantageously, catheter introducer 10 can be adapted to different insertion modules by means of at least one assembly aid 18 , 20 , 22 which can be removed without tools.
