Description

[0001] The present invention relates to a dialysis machine with a support for fluid containers. Background of the Revelation

[0002] Dialysis fluid or dialysis fluid concentrate for dialysis machines can be stored in fluid containers that are attached to the dialysis machine or placed on or next to the dialysis machine. For this purpose, conventional dialysis machines have a base with a support or storage surface on which the fluid containers containing dialysis fluid or dialysis fluid concentrate can be placed or stored. The dialysis machines can be mounted on casters and can thus be moved between different treatment rooms. Because the fluid containers are attached to the dialysis machine, they can be easily moved with the dialysis machine. However, when moving the dialysis machine, there is a risk that the fluid containers could tip over due to unevenness in the floor or other vibrations. Therefore, it is common practice to secure the fluid containers to the dialysis machine with straps or buckles.However, securing it is an additional step that must be performed by a user of the dialysis machine.

[0003] Fluid containers for dialysis fluid or dialysis fluid concentrate are known, for example, from DE 10 2022 118 053 ​​A1.

[0004] It is also known that dialysis machines have holders that are adapted to the shape of at least certain fluid containers. This allows the fluid container to be easily inserted into the corresponding holder. An example of such a holder for a fluid container is known from EP 3 325 037 B1. This principle is similar to familiar cup holders in cars. However, the holders usually only fit a specific container shape. In most cases, therefore, only fluid containers sold by the same manufacturer as the dialysis machine fit into the holder. In practice, however, a large number of different fluid containers with different shapes are available on the market and in use in hospitals. Brief description of the revelation

[0005] The object of the present disclosure is therefore to overcome or at least mitigate the disadvantages of the prior art and, in particular, to provide a dialysis machine to which fluid containers with different shapes or geometries can be easily and securely attached.

[0006] This object is achieved according to the disclosure by a dialysis machine according to claim 1. Furthermore, the object of the present disclosure is achieved by a system according to claim 14. The object is also achieved by using a support plate according to claim 16 and a support plate according to claim 17.

[0007] The present disclosure relates to an extracorporeal blood treatment machine or a dialysis machine with a removable / detachable support plate for at least one fluid container, in particular for a container for dialysis fluid or dialysis fluid concentrate. The support plate has a first surface and a second surface opposite the first surface. The first surface has at least one (convex) projection / dome or a (convex) bulge. The at least one (convex) projection is provided and designed to engage in or be received in a corresponding (concave) recess / recess in the fluid container. The second opposite surface differs from the first surface. The second opposite surface can, for example, be (substantially) planar / flat.Depending on the shape of the fluid container, the support plate is inserted into a base / receiving section of the dialysis machine in a first insertion orientation or a second insertion orientation. In the first insertion orientation, the first surface faces toward the base / receiving section, and in the second insertion orientation, the second surface faces toward the base / receiving section.

[0008] In other words, the support plate is inserted into the receiving section / base of the dialysis machine depending on the shape / outer contour of the fluid container in such a way that a side / surface of the support plate that matches the shape of the fluid container faces upwards or toward the fluid container. This means that the support plate can be inserted into the base / receiving section of the dialysis machine in a first orientation and in a further orientation that is upside down relative to the first orientation.

[0009] In other words, the dialysis machine has a reversible (support) plate or a reversible plate on which the fluid container(s) can be placed or placed. The reversible plate can be oriented in the appropriate direction based on the shape of the fluid container and can thus (together with the receiving section / base) form a suitable support / storage surface for the fluid container.

[0010] The at least one (convex) projection can be a bulge that protrudes (essentially perpendicularly) from the first surface and thus functions as a fastening element. The (convex) projection can therefore protrude from the first surface in a dome-shaped manner. This means that the shape of the protruding dome-shaped projection can form a dome that has the shape of a dome / a convex curvature. The (convex) projection can in particular be round / rotationally symmetrical. The shape of the projection can be adapted to the recess of the fluid container, such that the projection and the corresponding recess together represent a fastening.

[0011] The support plate can be formed essentially as a flat plate with the first surface and the second surface opposite the first surface. A circumferential surface can be formed between the two surfaces. The support plate can, of course, have several, in particular two, projections. A separate fluid container can then be placed on each of the plurality of projections.

[0012] The receiving section / base can be formed as part of the housing of the dialysis machine. The receiving section / base can form a support or storage surface for the fluid containers, accessible from above. The receiving section / base can also protrude from the housing like a balcony.

[0013] The fluid container can, in particular, be a fluid container for dialysis fluid or dialysis fluid concentrate. The fluid in the fluid container can be an acidic or basic concentrate, for example. Dialysis fluid can be produced from water mixed with an acidic component and a basic component. The acidic component can be a solution with sodium chloride, potassium chloride, magnesium chloride, calcium chloride, glucose, acetic acid and / or citric acid or with acetate. The basic component can be, for example, sodium bicarbonate or (bi)carbonate. Alternatively, the fluid container can be a container for a disinfectant.

[0014] The fluid container can be in the shape of a (round) bottle or a (square) canister. What both shapes have in common is that the fluid container has a base section from which a single circumferential side wall or several opposite side walls protrude. In particular, a (round) bottle can have a (round) base section that has a support surface for contact with the support plate and a recessed section that forms the concave recess. The recess of the bottle is prepared and designed to receive the (convex) projection. The projection can engage in the recess such that both components are fastened to one another. Preferably, an outer surface of the projection can bear against an inner surface of the recess, so that a frictional connection can be realized.

[0015] The canister / canister-shaped fluid container can have a substantially flat bottom portion. This means that a bottom-side outer surface of the fluid container can be substantially flat. Thus, the canister can have a large contact surface on the support plate.

[0016] The dialysis machine according to the disclosure allows fluid containers of different shapes or geometries to be placed and / or secured to the dialysis machine. Depending on the shape of the fluid container, a user can select the appropriate support plate geometry and insert the support plate into the dialysis machine so that the appropriate side / geometry faces upwards / towards the fluid container. If the fluid container is a bottle with a recess in the base section, the user can insert the support plate into the receiving section / base such that the second surface faces towards the receiving section / base and thus towards the base. As a result, the opposite first surface faces upwards or towards the fluid container and thus forms a storage surface / deposit surface / supporting surface for the fluid container.Due to the at least one (convex) projection, the support surface does not form a smooth / flat / plane surface, but rather a (supporting) surface with one or more fastening elements. When the fluid container is then placed on the support plate, the (convex) projection of the support plate engages in the corresponding concave recess of the fluid container on the support plate, or is at least received therein. Thus, an outer surface of the projection can bear (frictionally) against an inner surface of the recess. This engagement can secure the fluid container to the support plate and thus to the dialysis machine. However, according to the disclosure, it can also be provided that the outer surface of the projection does not bear against the inner surface of the recess.In this case, the projection of the support plate serves more as a positioning aid for the fluid container in order to place the fluid container in a suitable location, for example in such a way that another fluid container can be placed on the support plate next to this fluid container.

[0017] The (convex) protrusion can be used as a positioning aid, in addition to or as an alternative to the fastening or fixation. The protrusion indicates the optimal position for the fluid container to the user placing the fluid container on the support plate. This ensures that another fluid container can be placed next to the first. Since filled fluid containers can be heavy, it is advantageous if the user has to lift the fluid containers as little as possible.

[0018] If a fluid container is in the form of a canister with a flat base section, the user can insert the support plate into the receiving section / base such that the first surface points towards the receiving section / base. The second surface therefore points upwards in the opposite direction / towards the fluid container. This means that the flat / plane surface becomes a (essentially also flat) storage surface / storage surface / support surface for the fluid container. This allows the canister to be placed with the flat base section on the flat / plane storage surface. The flat / plane storage surface fits the flat base section so that the canister stands securely on the support plate and does not tip over even when the dialysis machine is moved. The flat / plane storage surface can be used to provide a universal holder that can accommodate fluid containers or canisters with different base sections.

[0019] The object of the present disclosure is further achieved by a system comprising the dialysis machine according to one of the preceding aspects and at least one fluid container.

[0020] Advantageous further developments of the disclosure are the subject of the appended subclaims.

[0021] According to an optional aspect of the present disclosure, the receiving portion / base can have a recess / recess / receptacle / free space into which the (convex) projection extends when the support plate is inserted in the first insertion orientation. This means that the projection can be received by the recess. In other words, the receiving portion / base has a support portion for the fluid containers and the (central) recess. The recess extends from the support portion towards the floor / towards the wheels of the dialysis machine. Since the projection of the support plate can be immersed in the recess, the projection does not lie directly on a support portion of the receiving portion / base and thus does not protrude from the receiving portion / base.

[0022] Preferably, the recess can be adapted to the shape of the support plate. This means that the recess can be shaped such that the support plate can be at least partially inserted into the recess.

[0023] The receiving section can preferably have a circumferential groove which surrounds the recess and wherein the support plate can rest on a groove end of the circumferential groove. In other words, the recess can have a circumferential support surface on which the support plate can rest. The support surface can be designed as a step in a side wall of the recess. I.e. the support surface can protrude from the side wall of the recess into the interior of the recess and can also be spaced parallel from the support section (towards a bottom of the recess). The distance between the support surface and the support section can in particular correspond to the thickness / height of the support plate. As a result, the support plate can end flush with the support section and form a substantially flat support or storage surface for the fluid containers.The support surface can be designed such that the support plate and a bottom of the recess are always spaced apart. This allows any liquid that has leaked from one of the fluid containers to drain away.

[0024] The recess and the support surface on which the support plate rests can together form a socket for the support plate. This means that the support plate can be inserted into the socket and secured by the socket against slipping laterally, i.e., in the width direction.

[0025] According to a further optional aspect of the present disclosure, a gap can be formed between the support surface or the socket and the support plate. This means that there can be a distance between the support surface and the support plate. The gap can be formed both in the longitudinal or width direction of the support plate and in the height or thickness direction of the support plate. The gap in the longitudinal or width direction of the support plate can be formed such that the support plate is smaller in a longitudinal and / or width direction than the socket or the recess in which the support plate is enclosed. This can create a gap between a circumferential surface of the support plate, which is formed between the two opposing surfaces, and the socket. The gap in the height or thickness direction of the support plate can be formed, for example, by spacers.The gap allows fluid that has leaked or spilled from one of the fluid containers to drain from the support plate. The fluid can then flow into the recess or into the interior of the receiving section / base, where it is collected.

[0026] Preferably, the bottom of the depression is inclined relative to the horizontal / has an angle to the horizontal so that the liquid flows in a defined direction and collects at a predetermined location at the bottom of the depression.

[0027] Preferably, the gap between the support plate and the support surface can be formed by spacers / support pins / distance pins that space the support plate from the support surface. The spacers can protrude, in particular, perpendicularly from the first surface and / or the second surface of the support plate. The spacers can be individual pins that are spaced apart from one another. However, the spacers can also be designed as thin, protruding webs that are interrupted by individual openings. The spacers can preferably be arranged in an edge section of the support plate. Thus, the spacers can rest on the support surface. Furthermore, the spacers can rest laterally on the socket and secure the support plate against lateral slippage.

[0028] Alternatively, the spacers / support pins / distance pins can also be formed on the support surface. The spacers can protrude upwards or toward the support plate from the support surface.

[0029] Preferably, the support plate can have openings for handling. The support plate can have a recess extending from one surface to the opposite surface through the thickness of the support plate. This allows the user to insert their fingers into the support plate and easily grasp the support plate, which sits flush with the socket.

[0030] According to a further optional aspect of the present disclosure, the at least one (convex) projection can form an opening on the second surface. The opening can be closed with a lid. Since the support plate has an approximately constant wall thickness, the (convex) projection can form a corresponding concave opening on the first surface. Liquid or bacteria can accumulate in the opening and cleaning the support plate can be made more difficult. Thus, it can be advantageous to close the opening with the lid. Due to the lid, the second surface can be substantially flat and form a flat support surface in the second insertion orientation.

[0031] The lid can be made of plastic and welded to the support plate. The lid can be attached to the support plate, particularly by laser welding.

[0032] The opening can also be formed without a lid. Thus, the second surface can have one or more deep recesses. Liquid can collect in these recesses, especially when the support plate is inserted in the second insertion orientation. Leaving the openings open can save material and manufacturing costs for the lids or for applying the lids.

[0033] Preferably, the at least one projection can have a bore / fluid outlet bore, which is positioned in particular at a point on the projection that is furthest from the first surface. Liquid can flow from the support plate into the recess through the fluid outlet bore.

[0034] According to a further optional aspect of the present disclosure, the support plate can be inclined relative to the horizontal. The support surface on which the support plate rests in the receiving section / base can be inclined at an angle relative to the horizontal. The angle of inclination can be, for example, between 2° and 5°, preferably 3°. Due to the inclination, liquid on the support plate can flow off in a defined direction. The liquid can thus collect in a predetermined location / recess / basin. The liquid can be wiped or vacuumed off from the predetermined collecting basin. The support surface of the receiving section / base can also be inclined relative to the horizontal. Thus, a continuous support surface for the fluid containers can be formed.

[0035] Preferably, the dialysis machine can have a leak sensor attached to the receiving section / base. The leak sensor can detect when fluid accumulates in the receiving section / base. The leak sensor can be connected to a control unit that processes a message about detected fluid and outputs it to the user. The leak sensor can, for example, be located at the lowest point at the bottom of the recess.

[0036] Alternatively, the support plate can be equipped with a leak sensor. The leak sensor can detect when liquid accumulates on the support plate.

[0037] According to an optional aspect of the present disclosure, the support plate may have only one projection. This allows two adjacent storage spaces for different fluid containers to be formed. A storage space for a bottle could be formed with a recess in the base portion, and adjacent thereto a storage space for a canister with a flat base portion.

[0038] The support plate may also form a projection on each of the two surfaces.

[0039] Preferably, the support plate can be fixed to the receiving section / base with one or more magnets. Alternatively, the support plate can also be fixed to the receiving section / base by a positive fit or another detachable connection.

[0040] The (convex) projection can preferably be detachably attached to the support plate. For example, the projection can be clipped or screwed. The projection can also be attached to the support plate by another detachable joining method.

[0041] The cover can be welded to the support plate, particularly by laser welding. Alternatively, the cover can be glued or attached to the support plate using any other material-to-material joining method.

[0042] The support plate can be manufactured, for example, by injection molding. Alternatively, the support plate can be manufactured using thermoplastic foam molding (TSG), reaction injection molding (RIM), or deep drawing. The support plate can also be 3D printed. The support plate can also be manufactured using a twin-sheet process. This allows two semi-finished products to be deep-drawn and joined simultaneously, allowing double-walled components to be formed in a simple process.

[0043] The materials used for the support plate can be PE, PP or PET or other weldable plastics, especially thermoplastics.

[0044] Furthermore, the object of the present disclosure is achieved by the use of the support plate in or on the dialysis machine, in particular a dialysis machine as described above. In particular, the support plate can be used as a base / storage surface / shelf for the fluid container on the dialysis machine. The support plate has the first surface and the second opposite surface. The first surface has the at least one projection. The at least one projection is provided and designed to engage in the corresponding recess of the fluid container or to be received therein. The second opposite surface differs from the first surface. In particular, the second opposite surface can be flat or planar.Depending on the shape of a bottom portion of the fluid container, the support plate is inserted or insertable into the receiving portion of the dialysis machine in the first insertion orientation or the second insertion orientation. In the first insertion orientation, the first surface faces toward the receiving portion, and in the second insertion orientation, the second surface faces toward the receiving portion.

[0045] By using the support plate as disclosed, fluid containers of different shapes can be arranged / attached to the dialysis machine or safely placed on (the receiving section) of the dialysis machine.

[0046] Furthermore, the present disclosure relates to a support plate for a dialysis machine, in particular a dialysis machine as described above, having the first surface and the second opposite surface. The first surface has the at least one projection, and the second opposite surface differs from the first surface. The at least one projection is provided and configured to engage or be received in the corresponding recess of the fluid container. The support plate can be provided and configured to be inserted into a receiving portion of the dialysis machine in a first insertion orientation or a second insertion orientation, depending on a shape of a base portion of the fluid container. Depending on the insertion direction, one of the first and second surfaces can point upwards or in the direction of the receiving portion of the dialysis machine.

[0047] The disclosed support plate enables a simple and quick change of the recording geometry on the dialysis machine.

[0048] Preferably, the at least one projection can form the opening on the second surface. Preferably, the support plate can have a cover that closes the opening. The cover can be welded to the opening.

[0049] Advantageously, the first surface and / or the second surface may further comprise protruding spacers which may protrude concavely from the respective surfaces.

[0050] The support plate can also be designed without the protruding spacers. This can be advantageous because the surface of the support plate is then flat / plane and can thus easily accommodate the canister-shaped fluid container. In this case, the spacers can advantageously be formed on the socket of the receiving section of the dialysis machine.

[0051] Particularly if the support plate does not have spacers, it can be advantageous to provide a geometry that prevents the support plate from slipping. For example, the receiving section can have one or more recesses into which one or more corresponding projections on the support plate can engage. Of course, the support plate can also have one or more recesses, and the receiving section can have one or more corresponding projections. The combination of recess and projection can then prevent the support plate from accidentally slipping relative to the receiving section.

[0052] It is of course also conceivable that the support plate has the spacers on only one of the two surfaces.

[0053] The at least one projection of the support plate can further comprise a bore, which can be positioned, in particular, at a point on the projection that is furthest from the first surface. Fluid can flow out of the opening through this bore, particularly if the opening is not closed by a cover.

Detailed description of the characters

[0054] Fig. Figure 1 shows a dialysis machine 1 with two fluid containers 2. The dialysis machine 1 has rollers on the underside of the dialysis machine 1, allowing it to be moved. The fluid containers 2 are placed on a receiving section / storage section / base 4 of the dialysis machine 1. Thus, the fluid containers 2 can be moved with the movable dialysis machine 1.

[0055] Fig. 2 shows a support plate 6, which rests in a first insertion orientation on or in the base 4. The base 4 has a substantially flat support section 8 for the fluid container 2 and a central socket / receptacle / free space / recess 10 for the support plate 6. The recess 10 has substantially the shape of the support plate 6. That is, an inner contour of the recess 10 is adapted to an outer contour of the support plate 6. A bottom 12 of the recess 10 (in Fig. 5) is offset parallel downwards / towards the bottom of the dialysis machine 1 compared to the support section 8. Thus, the recess 10 forms a free space in the base 4. The recess 10 has a support surface 14 (in Fig. 3), on which the support plate 6 rests. The support surface 14 is spaced parallel from the support section 8 and projects inward into the recess 10. Thus, the support surface 14 and the inner contour of the recess form a socket for the support plate 6. The distance between the support surface 14 and the support section 8 essentially corresponds to the thickness of the support plate 6. The support plate 6 thus rests on the support surface 14 such that the support plate 6 and the support section 8 are flush and form a common surface / plane. The support plate 6, together with the support section 8, thus forms an essentially continuous deposit or setting surface for the fluid containers 2. By being accommodated in the socket, lateral slipping of the support plate 6 is prevented. The longitudinal or lateral extent of the support plate 6 is smaller than the socket / recess 10.This creates a gap 16 between the support plate 8 and the recess 10. Liquid can drain through the gap 16 from the support plate 8 into the recess 10 of the base 4 and collect in the recess 10.

[0056] The support plate 6 has a first surface 18 and a second opposite surface 20 (in Fig. 4). The first surface 18 has two convex projections 22 that protrude from the first surface 18. In the first insertion orientation, the support plate 6 is oriented such that the second surface 20 points toward the base 4. Thus, the first surface 18 points upwards away from the base 4 and forms a storage surface for the fluid containers 2. The support section 8 is offset parallel to a wall end / edge 24 of the base 4 such that the edge 24 protrudes beyond the support section 8. Thus, liquid that leaks from the fluid containers 2 can be collected in the base 4.

[0057] When the fluid containers 2 are placed on the base 4, the projections 22 engage in corresponding recesses 26 on a base portion of the respective fluid container 2. Thus, the fluid container 2 can be fixed or secured in its position. This prevents the fluid container 2 from falling over when the dialysis machine 1 is moved. Furthermore, the projections 22 indicate the optimal position for the individual fluid containers 2. This ensures that two fluid containers 2 can be placed side by side on the base 4.

[0058] Fig. Figure 3 shows a section through the base 4 with the support plate 6 in the first insertion orientation, with one of the fluid containers 2 standing on the support plate 6. The convex projection 22 engages in the recess 26 of the fluid container 2. The recess 26 and the projection 22 are designed such that an outer surface 28 of the projection 22 rests against an inner surface 30 of the recess 26. Thus, the projection 22 supports the fluid container 2 and thus functions as a fastening element.

[0059] The support plate 6 has spacers / spacer pins / distance pins 32 that protrude substantially perpendicularly from the second surface 20. When the spacers 32 rest on the support surface 14, the gap 16 is formed between the support plate 6 and the support surface 14. Spilled liquid from the fluid containers 2 can flow through this gap 16 into the recess 10 of the base. The spacers 32 also rest against the recess 10 and thus prevent the support plate 6 from slipping laterally.

[0060] Fig. 4 shows the support plate 6 in a second insertion orientation. In the second insertion orientation, the first surface 18 points towards the base 4 and the second surface 20 points upwards and forms the storage surface. The second surface 20 is planar / flat. This means that the planar second surface 20 and the flush support section 8 of the base 4 together form a substantially planar / flat storage surface or shelf surface. Since the support plate 6 has a substantially constant plate thickness, the convex projections 22 each form a corresponding (concave) opening / bulge 34 in the second surface 20. These openings 34 are each closed by covers 36 so that the second surface 20 is flat and no liquid or bacteria can collect in the opening.The flat storage or depositing surface thus formed is designed to accommodate canister-shaped fluid containers 2 with a flat bottom. The canisters have a large contact surface on the support plate 6 and are thus well secured against tipping over.

[0061] In summary, the support plate 6 can be inserted into the base 4 in the desired / appropriate insertion orientation based on the shape of the fluid containers 2. Thus, the side / surface that best matches the shape of the fluid containers 2 always faces upwards.

[0062] Fig. 5 shows the base 4 without the support plate. The base has the support section 8 and the recess 10, which is formed centrally in the support section 8. The recess 10 is adapted to the shape of the support plate 6. The recess 10 has the support surface 14, which is spaced parallel from the support section 8. The support surface 14 and the contour of the recess form the holder for the support plate 8. A leakage sensor 38 is arranged at the lowest point of the recess 10. The leakage sensor 38 detects fluid that collects in the recess and issues a warning to a control unit (not shown) of the dialysis machine 1. The bottom 12 of the recess 10 is inclined relative to the horizontal so that fluid collects at a defined location. The bottom 12 is inclined towards the dialysis machine 1. The support surface 14 is also inclined relative to the horizontal.Thus, the support plate 6, which rests on the support surface 14, also has an angle relative to the horizontal. This allows liquid to drain from the support plate 6. The liquid preferably flows through the gap 16 between the support plate 6 and the socket into the recess 10.

[0063] Fig. 6 shows the first surface 18 of the support plate 6. The support plate 6 essentially has an elliptical basic shape 40 with a fastening section 42 that protrudes from the elliptical basic shape. The two round convex projections 22 protrude from the first surface 18. The support plate 6 has handling openings 44 for handling the support plate 6. The support plate 6 further has a number of protruding spacers 32. The spacers 32 rest on the support surface 14 and thus form the gap 16 or a distance between the support surface 14 and the support plate 6 when the support plate 6 is inserted into the base 4. Spilled liquid can drain through this gap 16 into the recess 10 in the base 4.

[0064] Fig. 7 shows the second surface 20 of the support plate 6. The openings 34 formed by the convex projection 22 on the second surface 20 are closed by the covers 36. The covers 36 can be welded to the support plate 36, in particular by laser welding. The second surface 20 also has a number of spacers 32 that protrude substantially perpendicularly from the second surface 20. The spacers 32 are each distributed around a circumference of the support plate 6.

[0065] Fig. 8 shows the two fluid containers 2 placed on the support plate 6. The fluid containers 2 are each designed as bottles 46 and have a recess 26. Therefore, the support plate 6 is aligned in the first insertion orientation. This means that the two convex projections 22 point upwards towards the bottles 46 and each engage with the bottles 46. Since the edge 24 of the base 4 protrudes beyond the support plate 6, the edge 24 can provide additional support for the bottles 46. The two bottles 46 have different volumes. As long as the recesses 26 of the bottles 46 match the projections 22, the bottles 46 can be secured by the projections 22.

[0066] Fig. 9 shows two additional fluid containers 2 positioned on the support plate 6 in the second insertion orientation. The fluid containers are shaped as canisters 48. The canisters 48 each have a flat bottom portion 50 from which four opposing side walls 52 protrude. The flat bottom portion 50 can be placed on the second surface 20 of the support plate 6. Due to the flat bottom portion 50, the canisters 48 have such a large support surface that no additional fastening element is necessary. The fluid containers 2 are supported at least in sections on the projecting edge 24 of the base 4.

[0067] Fig. Figure 10 shows a support plate 206 according to a second embodiment. The differences between the support plates of the individual embodiments are described below. Otherwise, the support plate 206 according to the second embodiment has all aspects of the support plate 6 according to the first embodiment. The support plate 206 is approximately rectangular. The support plate 206 according to the second embodiment is larger than the support plate 6 shown in the Fig. 2 to 8. The support plate 206 covers the support section 8 of the base 4 and is enclosed by the protruding edge 24 of the base 4. The outer contour of the support plate is thus adapted to the inner contour of the edge 24. The edge 24 protrudes beyond the support plate 206. Thus, no liquid can leak out of the base 4. In the circumferential direction, the gap 16 is formed between the support plate 206 and the edge 24. The first surface 18 of the support plate 206 has the two convex projections 22. The support plate 206 further has the handling openings 44 and the number of spacers 32.

[0068] Fig. 11 shows the support plate 206 in the second insertion orientation. The openings 34 of the second surface 20 are closed by the covers 36. Thus, the second surface 20 is substantially flat. The second surface 20 also has the spacers 32. As a result, the spacers 32 space the support plate 206 from the support portion 8 of the base 4, and liquid can drain from the support plate 206 into the recess 10 of the base 4.

[0069] Of course, the support plate 6, 206 can also have two projections 22, each of which has different sizes and is thus adapted for recesses 26 of different sizes.

[0070] Fig. 12 shows a support plate 306 according to a third embodiment. The support plate 306 according to the third embodiment essentially corresponds to the support plate 6 according to the first embodiment. The only difference is that the support plate 306 has a convex projection 22. This means that the first surface 18 of the support plate 306 has two different storage locations next to one another, one storage location for a bottle 46 having a recess 26, and the other storage location for a canister 48 having a flat bottom section 50.

[0071] Of course, the support plate 206 according to the second embodiment can also have only one convex projection 22 and thus also form two different storage spaces next to each other.

[0072] Fig.13 shows a support plate 406 according to a fourth embodiment. The support plate 406 has a bore / fluid outlet bore 54 in each of the convex projections 22. The support plate 406 preferably has no covers 36 on the openings 34. This means that in the second insertion orientation, fluid can collect in the (deep) openings 34. The fluid can drain from the support plate 406 into the recess 10 through the fluid outlet bores 54. In further embodiments, the support plate 406 can have handling openings 44 for handling the support plate 406 and / or a number of protruding spacers 32.
