[0003] Coupling device, housing and analysis system
[0004] State of the art
[0005] The invention relates to a coupling device, a housing and an analysis device system according to the preamble of the independent claims.
[0006] An analytical instrument system can consist of several analytical instruments. To securely connect the analytical instruments, at least one suitable coupling unit should be provided.
[0007] Disclosure of the invention
[0008] Against this background, the approach presented here introduces a coupling device, a housing, and an analysis device system according to the main claims. Advantageous further developments and improvements of the device specified in the independent claim are possible through the measures listed in the dependent claims.
[0009] The advantages achievable with the approach presented here consist in particular of creating a coupling device that can enable reliable coupling of at least two analyzers for an analyzer system.
[0010] A coupling device for connecting an analyzer to another analyzer and / or an additional analyzer for an analyzer system is presented. The coupling device comprises a lateral coupling element and, additionally or alternatively, a vertical coupling element. The lateral coupling element forms a first rail and a second rail. The first rail is designed to engage in a recess on the underside of the analyzer housing. The second rail is designed to engage in a recess on the underside of the additional analyzer housing, thus coupling the analyzer and the additional analyzer to each other by positive locking and / or friction locking.The vertical coupling element forms a protrusion on its upper side to engage in a protrusion-receiving recess of a housing of an additional analyzer, in order to couple the analyzer and the additional analyzer to each other in a form-fitting and / or force-fitting manner.
[0011] The analyzers can be compact devices for molecular diagnostics. Each analyzer can accommodate a cartridge. The cartridge can be a familiar lab-on-a-chip cartridge, which can be used, for example, to analyze a patient sample as a fluid. The cartridge can also include a microfluidic network for processing fluids. The analyzer system can comprise at least two analyzers, which can be coupled to each other using a coupling device, either positively or non-positively. The lateral coupling element can couple the analyzer and the other analyzer in parallel, while the vertical coupling element can couple the analyzer and the additional analyzer one above the other. The lateral coupling element and / or the vertical coupling element can be molded in one piece and manufactured, for example, using injection molding.
[0012] The approach presented here allows for the robust and well-defined arrangement of multiple analyzers in at least two rows, stacked vertically, in a precise orientation relative to one another, for example, in a minimum 2x2 configuration. Furthermore, this approach also enables the consistent alignment of a single row of analyzers. This approach can also be understood as a stacking system for analyzers, which can also be referred to as laboratory instruments. In other words, in point-of-care settings such as hospitals or laboratories, the available floor space for analyzers can be very limited and a crucial factor in procurement. The coupling device allows for the parallel placement and / or uniform alignment of multiple analyzers, for example, with regard to spacing in depth, width, and rotation angle.To minimize and optimally utilize the footprint, users can be enabled to stack analysis devices on top of each other without using an additional shelf.
[0013] The rails can be aligned parallel to each other. The lateral coupling element can thus be designed to couple the analyzer and the other analyzer in parallel to each other. The lateral coupling element can, for example, be designed as a parallel aligner.
[0014] The vertical coupling element can be configured to couple the analyzer and the additional analyzer one above the other. In particular, the vertical coupling element can be configured as a depth stop element.
[0015] The first rail can have a first locking element. This first locking element can be designed to engage in a groove in the housing of the analyzer. Additionally or alternatively, the second rail can have a second locking element. This second locking element can be designed to engage in a groove in the housing of the other analyzer. In this way, a secure and reliable coupling of the lateral coupling element to the analyzer and the other analyzer is ensured. Furthermore, the lateral coupling element can be manually removed from the grooves.
[0016] The first locking element can be located on the side of the first rail facing the second rail. Additionally or alternatively, the second locking element can be located on the side of the second rail facing the first rail. The raised section can be shaped like a pylon. This allows for a secure and reliable coupling of the vertical coupling element to the additional analyzer.
[0017] The vertical coupling element can form a clamping element to engage in a recess on a side wall of the analyzer housing. Additionally or alternatively, the clamping element can be formed on the opposite side of the vertical coupling element from the protrusion. In particular, the clamping element can be U-shaped. This can enable a secure and reliable coupling of the vertical coupling element to the analyzer.
[0018] The vertical coupling element can form a projection on its upper side, opposite the clamping element. This projection can be designed to engage in a groove in the analyzer housing. This can ensure a secure and reliable coupling of the vertical coupling element to the analyzer.
[0019] The vertical coupling element can be at least partially tapered on the side of the projection opposite the clamping element to allow for manual removal of the vertical coupling element from the analyzer. This enables a user to remove the vertical coupling element from the analyzer easily and quickly.
[0020] A housing for an analytical instrument has a lateral receiving recess for receiving at least one rail of the lateral coupling element of an embodiment of a coupling device mentioned herein, and at least one vertical receiving recess for receiving at least one clamping element and / or a projection of the vertical coupling element of an embodiment of a coupling device mentioned herein. The lateral receiving recess can, for example, be formed as a depression to receive the first rail of the lateral coupling element. Additionally or alternatively, the lateral receiving recess can, for example, be formed as a groove to receive the first locking element of the lateral coupling element. The vertical receiving recess can, for example, be formed as a groove to receive the projection of the vertical coupling element.Additionally or alternatively, the vertical receiving recess can, for example, be shaped as a recess to accommodate the clamping element of the vertical coupling element.
[0021] An analysis system comprises an embodiment of a coupling device described herein. The analysis system includes an analysis device and / or a further analysis device and / or an additional analysis device, which are coupled and / or can be coupled to one another by means of at least the lateral coupling element and / or the vertical coupling element. This enables a secure arrangement of the analysis devices. The analysis device and the further analysis device can, for example, be arranged parallel to one another by means of the lateral coupling element. The analysis device and the additional analysis device can, for example, be arranged one above the other by means of the vertical coupling element.

[0038] In the following description of favorable embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various figures and acting similarly, without repeating these elements.
[0039] Fig. 1 shows an embodiment of an analysis system 100.
[0040] The analyzer system 100 comprises an analyzer 105, a further analyzer 110, and optionally an additional analyzer 115 and a fourth analyzer 120. According to one embodiment, the analyzer 105 and the further analyzer 110 are arranged parallel to each other. The additional analyzer 115 and the fourth analyzer 120 are, for example, arranged parallel to each other, with the additional analyzer 115 positioned above the analyzer 105 and the fourth analyzer 120 positioned above the further analyzer 110.
[0041] The analyzers 105, 110, 115, and 120 are coupled to each other by means of a coupling device, which is not visible in Fig. 1. The coupling device has a lateral coupling element and a vertical coupling element. For example, the analyzer 105 and the additional analyzer 110 are coupled parallel to each other by means of the lateral coupling element. For example, the analyzer 105 and the additional analyzer 115 are coupled one above the other by means of the vertical coupling element. Additionally or alternatively, the additional analyzer 115 and the fourth analyzer 120 are coupled parallel to each other by means of another lateral coupling element. Additionally or alternatively, the additional analyzer 110 and the fourth analyzer 120 are coupled one above the other by means of another vertical coupling element. The coupling device is shown and described in more detail in the following figures.
[0042] Fig. 2 shows an embodiment of a coupling device 200. The coupling device 200 is designed to couple one analyzer and another analyzer together, for example the analyzers shown in Fig. 1.
[0043] The coupling device 200 includes a lateral coupling element 205, which can also be referred to as a parallel aligner. The lateral coupling element 205 is, for example, formed in one piece.
[0044] The lateral coupling element 205 forms a first rail 210 and a second rail 215, wherein the rails 210 and 215 are aligned, for example, parallel to each other. The first rail 210 is designed to engage in a recess on the underside of a housing of the analyzer, as shown by way of example only in Fig. 15 and / or Fig. 16. The second rail 215 is designed to engage in a recess on the underside of a housing of the further analyzer, as shown by way of example only in Fig. 15 and / or Fig. 16. In this way, the lateral coupling element 205 couples the analyzer and the further analyzer to each other by means of a positive and / or force-fit connection.
[0045] According to one embodiment, the first rail 210 has a first locking element 220. The first locking element 220 is, for example, arranged on one side of the first rail 210 facing the second rail 215.
[0046] The first locking element 220 is designed, for example, to engage in a groove in the housing of the analyzer. The second rail 215 has a second locking element, which is not visible in the view shown here. The second locking element is designed to engage in a groove in the housing of the other analyzer. For this purpose, the second locking element is arranged, for example, on one side of the second rail 215 facing the first rail 210.
[0047] According to one embodiment, the lateral coupling element 205 has a surface 225 between the rails 210, 215 which is designed to create a distance between the analysis devices.
[0048] In other words, the lateral coupling element 205 engages with a rail 210, 215 in a recess on the underside of an analyzer, so that the two undersides and thus the two analyzers are aligned parallel to each other with a gap of predetermined width between them.
[0049] The rails 210, 215 preferably have locking elements 220 on their inner side, or optionally alternatively on their outer side. These locking elements can also be described as elongated projections. The locking elements 220 are designed, for example, to engage in a groove in the housing of the analyzer, allowing for a clip connection between the respective rail 210, 215 and the analyzer. The locking elements 220 are designed, for example, with recesses on the inner side and, due to the material of the rail 210, 215, as spring elements made of plastic. This prevents the lateral coupling element 205 from falling out.
[0050] According to one embodiment, the rails 210, 215 are, for example, designed to be long, thereby reducing tolerances for the angle of rotation between the analysis devices.
[0051] Fig. 3 shows an embodiment of a coupling device 200. The coupling device 200 is similar to or corresponds to the coupling device from Fig. 2 except that a side view of the coupling device 200 is shown.
[0052] Fig. 4 shows an embodiment of a coupling device 200. The coupling device 200 is similar to or corresponds to the coupling device from one of the figures described above, except that a bottom view of the coupling device 200 is shown.
[0053] Shown are the first locking element 220 and the second locking element 400.
[0054] Fig. 5 shows an embodiment of a coupling device 200. The coupling device 200 is similar to or corresponds to the coupling device from one of the figures described above, except that a section through the coupling device 200 is shown.
[0055] Fig. 6 shows an embodiment of a coupling device 200. The coupling device 200 is designed to couple an analyzer and an additional analyzer, for example the analyzers shown in Fig. 1.
[0056] The coupling device 200 has a vertical coupling element 600, which can also be referred to as a depth stop. The vertical coupling element 600 forms a projection 605 on its upper side, the projection 605 being, for example, shaped like a pylon.
[0057] The projection 605 is designed to engage in a projection receiving recess of a housing of an additional analyzer in order to couple the analyzer and the additional analyzer to each other in a form-fitting and / or force-fitting manner, as shown only by way of example in Fig. 13.
[0058] The vertical coupling element 600 is designed, for example, to couple the analyzer and the additional analyzer one above the other, as shown only by way of example in Fig. 1. According to one embodiment, the vertical coupling element 600 has a square base.
[0059] The vertical coupling element 600, for example, forms a clamping element 610 to engage in a recess on a side wall of the housing of the analyzer, as shown only by way of example in Fig. 13. The clamping element 610 is, for example, U-shaped.
[0060] The vertical coupling element 600 prevents relative movement of two superimposed analyzers along the direction of the rails by means of the clamping element 610, which can also be referred to as a clamp, engaging at the upper end of the rear of the lower analyzer, and the projection 605, which engages in the additional analyzer, which can also be referred to as the upper analyzer, and which is located on the top of the vertical coupling element 600.
[0061] In other words, the vertical coupling element 600 comprises the clamping element 610, wherein the upper surface of the vertical coupling element 600, which can also be referred to as the upper clamping arm, has the projection 605 for engaging a recess on the underside of an analyzer. The clamping element 610, which can also be referred to as the lower clamping arm, engages in a recess in the upper region of the rear of the analyzer, which can also be referred to as the bottom analyzer. The vertical coupling element 600 forms a projection, see Fig. 7, for locking the vertical coupling element 600 in said recess in the upper region of the rear of the analyzer. The clamping element 610 has, for example, a projection on its inner side, see Fig.7, which engages in a recess in the top of the analyzer and, when the clamping element 610 is subjected to load by the additional analyzer, prevents the clamping element 610 from being pulled out of the back of the analyzer.
[0062] The vertical coupling element 600 has a tapered section at its tip to form a gap or tab in the area of the tapered section between the upper clamp arm and the top of the analyzer. This gap or tab allows, for example, a fingernail to be used to remove the vertical coupling element 600 from the analyzer, as shown in Fig. 9. When the additional analyzer is in place, this gap or tab is practically inaccessible.
[0063] A recess 615 in the vertical coupling element 600 has no functional significance, but is necessary for demolding in the injection molding tool.
[0064] The vertical coupling element 600 prevents the additional analyzer from shifting backwards, especially due to backward pressure during device use, for example when inserting a cartridge.
[0065] The use of at least two vertical coupling elements 600 and the connection of two analyzers with a lateral coupling element ensures that the upper analyzers no longer twist.
[0066] Fig. 7 shows an embodiment of a coupling device 200. The coupling device 200 is similar to or corresponds to the coupling device from Fig. 6 except that a side view of the coupling device 200 is shown.
[0067] The projection 700 is designed to engage in a groove in the housing of the analyzer, see Fig. 13. Fig. 8 shows an embodiment of a coupling device 200. The coupling device 200 is similar to or corresponds to the coupling device from Fig. 7, except that an additional side view of the coupling device 200 is shown.
[0068] Fig. 9 shows an embodiment of a coupling device 200. The coupling device 200 is similar to or corresponds to the coupling device from one of the figures described above, except that a bottom view of the coupling device 200 is shown.
[0069] Adjacent to the projection 700, the vertical coupling element 600 is at least partially tapered in order to allow the vertical coupling element 600 to be manually removed from the analyzer.
[0070] Fig. 10 shows an embodiment of a coupling device 200. The coupling device 200 is similar to or corresponds to the coupling device from one of the figures described above, except that the coupling device 200 is arranged on an analyzer 105 or on a housing 1005 of the analyzer 105.
[0071] The coupling device 200 comprises the lateral coupling element 205, the vertical coupling element 600 and optionally another lateral coupling element 1000.
[0072] The vertical coupling element 600 is arranged on a top side of the analyzer 105 and is designed to couple the analyzer 105 with an additional analyzer.
[0073] The lateral coupling element 205 is arranged with the first rail on a bottom side of the analyzer 105 and is designed to couple the analyzer 105 with another analyzer.
[0074] Optionally, the additional lateral coupling element 1000 is arranged on a top side of the analyzer 105 and is designed to laterally couple a second level to it and, for example, align it with the lower level, including the analyzer 105, via the vertical coupling element 600. Fig. 11 shows an embodiment of an analyzer system 100. The analyzer system 100 is similar to or corresponds to the analyzer system from Fig. 1, except that the coupling device 200 is arranged on the analyzer 105 and on the additional analyzer 110.
[0075] The analyzers 105 and 110 are shown only as examples.

The additional lateral coupling element 1000 is, for example, arranged on the housings 1005 and 1105 of the analyzers 105 and 110.
[0076] The additional vertical coupling element 1100 is, for example, arranged on a top side of the additional analyzer 110 and is designed to couple a fourth analyzer to the additional analyzer 110.
[0077] In other words, a minimal configuration of 2x2 analyzers can be achieved by using two vertical coupling elements 600, 1100 and two lateral coupling elements 1000, see also Fig. 1. The use of only the lateral coupling elements 1000 allows for a simple series of analyzers of any length with the same slit widths.

The analysis system 100 is similar to or corresponds to the analysis system from one of the figures described above, except that a bottom view of the analysis system 100 is shown. More precisely, a bottom view of the analysis device 105 and the further analysis device 110 is shown, wherein the coupling device 200, more precisely the lateral coupling element 205, couples the analysis devices 105 and 110 to each other.
