(28) FIG. 1 shows a base rack 10 of a device arrangement which can be configured in various ways for performing specific unit operations in biopharmaceutical processes using single-use process components. The base rack 10 provided for multiple use is shown here as a stainless steel trolley having numerous interfaces and a display 12.

(29) The base rack 10 has a plurality of rails 14 with markings. As shown in FIGS. 2 and 3, a plurality of mounting plates 16 can be releasably attached to the rails 14. For this purpose, the mounting plates 16 are provided with fastening portions 18, here in the form of clamps, by means of which the mounting plates 16 can be attached firmly, but preferably releasably, to one or more rails 14 of the base rack 10, for example by means of a releasable latching or snap-on connection. In principle, the mounting plates 16 can be attached not only to rails 14 but also to other fastening sites of the base rack 10.

(30) In the example configuration shown in FIGS. 2 and 3, different mounting plates 16 are joined together to form a large, continuous mounting surface. Adjacent mounting plates 16 are connected to each other, preferably in a releasable manner, to generally provide a stable mounting surface.

(31) The mounting plates 16 altogether contain a multitude of receptacles 20, in particular in the form of openings, which are arranged in a grid or are provided at specific predetermined sites. The receptacles 20 are used to attach universal holders (which will be explained in more detail later) or specific holders adapted to specific single-use process components, or they are designed for the direct reception of specific single-use process components. However, in the case of through holes, it is also possible to pass hose lines or other lines or components to the other side of the mounting plates 16.

(32) In addition to or in place of the receptacles 20, the mounting plates 16 may also have other holding means to fix specific components required for the respective process.

(33) FIG. 4 shows a base rack 10 of the device arrangement in which, by way of example, four hose fixing elements 22 and two universal holders 24 are releasably attached directly, i.e. without mounting plates 16, to the rails 14. One capsule holder 26 is inserted in each of the universal holders 24.

(34) Different holders and functional elements of the device arrangement will be described in detail in the following.

(35) FIG. 5 shows a single hose fixing element 22 according to a first variant. A multitude of hose receptacles 30 for the local fixing of one or more hose lines 32 extends from the front side of a square base plate 28 which is substantially square here, and over the entire circumference. The diameters of the hose receptacles 30 are slightly smaller than the diameter of the hose lines 32 to be fixed. The hose receptacles 30 or the entire hose fixing element 22 may be elastic, in particular to facilitate the reception (and, if necessary, the later removal) of relatively stiff hose lines 32 or rigid pipes.

(36) The rear side of the hose fixing element 22 is provided with a fastening portion 18, here in the form of a clamp, by means of which the hose fixing element 22 can be attached firmly, but preferably releasably, to one of the rails 14 of the base rack 10, for example by a releasable latching or snap-on connection. In principle, it is also possible to attach the hose fixing element 22 to another fastening site of the base rack 10 or to a mounting plate 16.

(37) A receptacle which serves to fix a sensor or another component required for the desired process is formed in the base plate 28 of the hose fixing element 22.

(38) As can be seen in FIG. 4, one or more hose lines 32 can be fixed locally by means of a hose fixing element 22, wherein depending on the depth of the hose receptacles 30, one or more hose lines 32 may be fixed per hose receptacle 30.

(39) Usually, it is provided that a hose line 32 is respectively received in two different hose receptacles 30 of a hose fixing element 22. In the simplest case, the hose line 32 is received in two opposite hose receptacles 30 of the hose fixing element 22, so that the hose fixing element 22 supports a straight course of the hose line 32.

(40) However, due to the circumferential arrangement of the hose receptacles 30, it is also possible to redirect hose lines 32 at different angles, e.g. to achieve a stable change of direction by 90 without the risk of kinking the hose line 32. In general, the fixing of the hose lines 32 in the hose receptacles 30 of the hose fixing elements 22 provides for a strain relief of the hose lines 32.

(41) Due to the multitude of hose receptacles 30 in a hose fixing element 22, a plurality of hose lines 32 can be moved past each other in a defined manner without the hose lines 32 affecting each other. Unintentional deflection of a hose line 32, which could then possibly drag along another hose line 32, is prevented by the hose fixing elements 22.

(42) If a sensor or another process component is fixed in the central receptacle of the hose fixing element 22, the hose line 32 leading to or away from this component can be fixed in the hose receptacles 30 such that the hose line connections are not under mechanical tension or only under low mechanical tension.

(43) FIG. 6 shows another variant of a hose fixing element 22 with an associated holding element 34. The hose fixing element 22 is here configured like a double-sided crown. Based on a ring shape, a plurality of hose receptacles 30 are here also formed over the entire circumference. The hose receptacles 30 of a first group are open in a first axial direction with respect to the center axis of the ring shape, while the hose receptacles 30 of a second group are open in an opposite second axial direction. The hose receptacles 30 of the first and the second group can be arranged directly opposite each other or offset from each other.

(44) Due to the double-sided design of this variant of the hose fixing element 22, the hose lines 32 can be guided in two different planes, as shown in FIG. 7. In principle, it is also possible to transfer a hose line 32 from one plane to the other plane.

(45) To reduce the load on the hose lines 32 in the hose receptacles 30 of the hose fixing element 22, holding elements 34 having enlarged hose supporting surfaces may be inserted into the hose receptacles 30. This also applies to the first variant shown in FIGS. 4 and 5 and to further variants of the hose fixing element 22.

(46) A further optional functional element for use with a hose fixing element 22 is the cover 36 shown in FIG. 8 as an example. The cover 36 is adapted to the basic shape of the hose fixing element 22 and can be placed so as to close the hose receptacles 30. To this end, the cover 36 can be fixed to the areas between the hose receptacles 30, for example by means of a clamp connection.

(47) FIG. 9 shows a universal holder 24 which has a fastening portion 18 on its rear side, here in the form of a clamp, for a firm, preferably releasable attachment to a rail 14, to another fastening site of the base rack 10 or to a mounting plate 16.

(48) On its front side, the universal holder 24 has a universal receptacle 38, which is open at the top and closed at the bottom. The front side of the universal receptacle 38 has a slot-like opening. A standardized fixing portion 40 of a holder, of a guide element or of another functional element can be inserted into the universal receptacle 38 from the top and, if necessary, be removed in the reverse direction. As an option, a releasable latching or snap-on connection can be provided between the universal receptacle 38 and the uniform fixing portion 40.

(49) FIG. 10 shows a hose holder 42, which is intended to be received in a universal holder 24. The hose holder 42 has a uniform fixing portion 40 which is adapted to the universal receptacle 38, which is shown here in the form of a substantially square plate, and from which a transition portion having an integrally molded holding portion 44 extends. The transition portion is dimensioned so as to fit through the slot-like opening of the universal holder 24. A hose line 32 can be clamped into the holding portion 44 of the hose holder 42 and can thus be fixed.

(50) As shown in FIG. 11, the hose holder 42 can be inserted in different orientations into the universal receptacle 38 of the universal holder 24 so that a hose line 32 can be fixed in correspondingly different orientations.

(51) FIG. 12 shows a connecting element 46 having two opposite universal receptacles 38. The universal receptacles 38 are configured in the same way as the universal holders 24 described above. If two hose holders 42 are inserted into the connecting element 46 as shown in the example configuration of FIG. 13, it is possible to fix two hose lines 32 in specified orientations relative to each other.

(52) The connecting element 46 may also have more than two universal receptacles 38, and other functional elements having uniform fixing portions 40 may be used instead of the hose holders 42.

(53) FIG. 14 shows a capsule holder 26, which is intended to be received in a universal holder 24, as shown in FIG. 15. The capsule holder 26 is basically similar in design to the hose holder 42 described above. The holding portion 48 of the capsule holder 26 is however provided for receiving filter capsules (filter cartridges) of a specific size (diameter) and is dimensioned accordingly.

(54) Otherwise, as with the hose holder 42, a uniform fixing portion 40, here again in the form of a substantially square plate, and a narrow transition portion between the fixing portion 40 and the holding portion 48 are provided. The universal receptacle 38 of the universal holder 24 and the uniform fixing portion 40 of the capsule holder 26 are again adapted to each other such that the capsule holder 26 can be inserted into the universal holder 24 in different orientations. This makes it possible to fix a filter capsule vertically, horizontally or, if necessary, in another orientation.

(55) A plurality of uniform fixing portions 40 are integrally formed over the (not completely closed) holding portion 48 of the capsule holder 26. The direction from which a filter capsule can be pressed into the capsule holder 26 depends on which of the uniform fixing portions 40 is inserted into the universal receptacle 38 of the universal holder 24.

(56) FIG. 16 shows an example configuration in which two capsule holders 26 are connected to each other by means of a connecting element 46 and are each inserted into a universal holder 24. Such an assembly can be attached as a stable unit to the base rack 10 of the device arrangement or to a mounting plate 16. The use of such connecting elements 46 reduces the number of individual components and reduces the assembly complexity for the user. The use of standardized connecting elements 46 which are identical in design can also minimize the number of connection steps required, which reduces the risk of leakage and contamination.

(57) FIG. 17 shows other variants of the universal holder 24 and of the capsule holder 26 which are adapted to each other. Here, the universal holder 24 has a circular universal receptacle 38 into which a uniform fixing portion 40, here in the form of an elastically compressible pin, of the capsule holder 26 or of another functional element can be clipped. To this end, the uniform pin has recesses 50 distributed around the circumference so that the portions located therebetween can be pressed inwards. At its free end, the uniform pin has latching portions 52 which, due to the elasticity of the uniform pin, can engage behind the rear edge of the round universal receptacle 38. The special feature of this type of connection is that the capsule holder 26 (or any other functional element having such a uniform pin) can assume various rotational positions in the universal receptacle 38, as indicated in FIG. 18.

(58) FIG. 19 shows two capsule holders 26 which can be connected to each other. One of these two capsule holders 26 corresponds to the capsule holder 26 shown in FIGS. 17 and 18 with an elastic uniform pin as fixing portion 40. The other capsule holder 26 has a universal receptacle 38 on the outside of its holding portion 48 which is designed in the same way as that of the universal holder 24 shown in FIGS. 17 and 18. The two capsule holders 26 can be connected to each other by clipping the uniform pin of one capsule holder 26 into the universal receptacle 38 of the other capsule holder 26, as already described above. In the mounted state, the capsule holders 26 can be rotated relative to each other, as indicated in FIG. 20, i.e. the filter capsules received therein can be arranged in a desired orientation relative to each other.

(59) FIG. 21 shows an exemplary kit including a hose fixing element 22, two holding elements 34 and a double capsule holder 54. The hose fixing element 22 and the holding elements 34 have already been described with reference to FIGS. 6 to 8, so that it is not necessary to explain them further. The double capsule holder 54 has two holding portions 48 which are firmly connected to each other and into which one respective filter capsule can be inserted. A connecting portion which is adjoined by a cylindrical portion 56 extends from the two holding portions 48. The cylindrical portion 56 is adapted to the supporting surfaces of the holding elements 34.

(60) As shown in FIG. 22, the two holding elements 34 can be inserted into opposite hose receptacles 30 of the hose fixing element 22 to receive the cylindrical portion 56 of the double capsule holder 54. In this context, it is advantageous that the holding elements 34 are configured so as to be elastic. Depending on the orientation in which the hose fixing element 22 is attached to the base rack 10 of the device arrangement or to a mounting plate 16, the orientation of the filter capsules received in the double capsule holder 54 changes accordingly.

(61) FIG. 23 shows a component holder 58 by means of which a sensor 60 (see FIG. 24) or another component can be attached to the base rack 10 of the device arrangement or to a mounting plate 16. The rear side of the component holder 58 has two integrally molded, uniform fixing portions 40 that are adapted to the universal receptacles 38 of the previously described universal holders 24. Two universal receptacles 38 of this kind are formed on the front side of the component holder 58. A receptacle 62 for a sensor 60 or another component that can be inserted therein is formed in the middle.

(62) FIG. 24 shows an example configuration including such a component holder 58. The two uniform fixing portions 40 of the component holder 58 are inserted into the universal receptacles 38 of two universal holders 24, which in turn may be attached to a rail 14 of the base rack 10 of the device arrangement. Two hose holders 42 are inserted into the universal receptacles 38 of the component holder 58. A sensor 60 having two fluid connections 64, 66 is received in the receptacle 62. The components are adapted to each other such that two hose lines 32 can be received in the hose holders 42 and can be connected to the fluid connections 64, 66 of the sensor 60 without significant mechanical stress.

(63) FIG. 25 shows another variant embodiment of the component holder 58 by means of which a valve, more precisely a hose pinch valve, can be attached to the base rack 10 of the device arrangement or to a mounting plate 16. In this case, the receptacle 62 is adapted to such a valve. The fixing portions 40 of the component holder 58 can absorb the pressing forces acting on the hose pinch valve.

(64) FIG. 26 shows a partial assembly of a process device arrangement with a plurality of filter capsules 68. The filter capsules 68 are at least partially integrated into the process device by rigid pipes 70. In order to ensure a stable arrangement of the filter capsules 68 and other components relative to each other, a rigid frame 72 is provided, which may be composed of a plurality of individual frame elements, if necessary. The filter capsules 68 and other components are fixed in the frame 72 such that they cannot move relative to each other. In this way, loads on the pipes 70 and the connections of the components are avoided. The frame 72 can be attached as a whole to the base rack 10 or to mounting plates 16 of the device arrangement, for example using the universal holders 24 described above. For this purpose, the frame is provided with uniform fixing portions 40.

(65) The holders and functional elements shown in the figures, which are intended for direct or indirect attachment to the base rack 10, are only exemplary designs. Specific functional portions (e.g. universal receptacles 38, fixing portions 40, holding portions 44, 48 etc.) and/or properties (elasticity etc.) of the functional elements can be provided in any combination. The holders and functional elements are preferably made of plastic and can usually be produced by injection molding or 3D printing and sterilized before delivery.

(66) In order to support the simplest and most error-free process setup possible, in particular with regard to the attachment of the single-use process components to the base rack 10 of the device arrangement, one or more of the following measures may be provided, in particular to define clear assembly positions and conditions: The rails 14 of the base rack 10 and/or other fastening sites of the base rack 10 and/or the mounting plates 16 (hereinafter generally referred to as fastening sites only) are provided with position marks, e.g. with a punched scale. The universal holder 24 or other holders or functional elements, such as the hose fixing elements (hereinafter generally referred to as holders only), which are to be attached to fastening sites, are provided with position markings referring to the position marks. A construction plan for the process setup of the device arrangement contains positional information for the holders. The holders are provided with individual markings, each of which matches an individual marking on a fastening site. The holders are provided with permanent magnets, and only specific predetermined areas of the fastening sites are ferromagnetic, so that the user can see where to place the holders due to magnetic attraction. The fastening sites have an electronic display to signal where to place each holder depending on the selected process setup. The holders have an electronic display to confirm the position thereof (independent of a control means of the device arrangement). The display of the holders can be used alternatively or additionally to visualize current measured values or other process relevant information. An adjustment of the correct positioning of the holders and/or of the process components is carried out by means of a camera (e.g. of a smartphone or a tablet) and an image evaluation. The holders and/or the process components attached therewith can be connected by radio to a central control means. The holders and/or the process components can for example be provided with RFID tags which can be read by a reader of the control means. By means of the radio link, it is possible to identify the installed process components and/or confirm the correct position thereof in the process setup. An automatic adoption of process parameters (e.g. operating pressure, type of process) is thus also possible.
