[0001] The present invention relates to a container holder according to claim 1. It also relates to a device according to claim 11.
[0002] Devices for therapeutic apheresis, liver support therapy, oxygenation, peritoneal dialysis, hemofiltration, or hemodialysis are known in practice. They can be connected to containers containing the fluids used in the treatment for the patient. Devices of the aforementioned type are collectively referred to as dialysis devices.
[0003] WO 2017 / 019640 A1 discloses a Infusate Caddy for carrying, organizing and operating infusion containers for dialysis.
[0004] WO 2017 / 093235 A1 discloses a medical fluid bag holder and methods for its manufacture, a medical weighing device and treatment device.
[0005] An infusion holder is known from WO 2018 / 022169 A1.
[0006] WO 2018 / 022170 A1 discloses a frame for infusion containers.
[0007] An object of the present invention is to propose a holder for holding such containers (in short: container holder) on devices as well as a device connected to at least one such container holder.
[0008] The object of the invention is achieved by a container holder having the features of claim 1. It is further achieved by a device having the features of claim 11.
[0009] The present invention relates to a container holder for a dialysis device. The container holder according to the invention comprises a first container receptacle, which is designed to receive a first container, and a second container receptacle for receiving a second container.
[0010] Optionally, the container holder has only the first container holder or only the second container holder, but no further container holders.
[0011] The container holder has a fastening section for its movable fastening or for its movable fastening to the dialysis device.
[0012] The movable fastening may optionally be in the form of a folding device, a sliding device and / or a detachable fastening device or be ensured by these; in some embodiments, a movable fastening may therefore also be understood as a detachable fastening, while in others it is not detachable.
[0013] A movable attachment can optionally allow relative movement between the container holder and the dialysis device.
[0014] A detachable fastening can optionally be such that the container holder can be removed from the dialysis machine without the use of tools and can preferably also be reattached to the dialysis machine without tools.
[0015] The present invention also relates to a dialysis device. This device comprises a container holder according to the invention.
[0016] The dialysis device according to the invention comprises a receptacle which is designed for its movable connection to a fastening section of the container holder on a holding section of the dialysis device.
[0017] The device (synonym: a corresponding mechanism, both terms are interchangeable and encompassed by the present invention) for folding, shifting or releasing can be provided by corresponding devices on either the dialysis device or the container holder or on both devices, namely the dialysis device and the container holder.
[0018] The connection between a main body of the dialysis machine and the container holder can be provided on the rear side of the main body, with the front side having a plurality (i.e., at least two) of control elements for a treatment. For example, a blood pump, a clamp for a tube that carries blood during operation, and / or holders for a tube that carries blood during operation and / or for a cassette that carries blood during operation can be arranged on the front side.
[0019] In all statements made herein, the use of the expression "may be" or "may have" etc. is to be understood as synonymous with "is preferably" or "preferably has" etc. and is intended to explain embodiments.
[0020] Embodiments may include one or more of the features mentioned above or below. The features mentioned herein may be the subject of embodiments of the invention in any combination, provided that a person skilled in the art does not recognize a specific combination as technically impossible.
[0021] Embodiments are further subject of the subclaims and embodiments.
[0022] Whenever numerical terms are mentioned herein, the person skilled in the art will understand this as an indication of a numerical lower limit.
[0023] Unless this leads to a contradiction recognizable to the skilled person, the skilled person will therefore always read "at least one" or "at least one" alongside the term "a" or "an." This understanding is encompassed by the present invention, as is the interpretation that a numerical word such as "a" can alternatively be meant as "exactly one," wherever this is recognizably technically possible to the skilled person. Both are encompassed by the present invention and apply to all numerical words used herein.
[0024] Whenever an embodiment is mentioned herein, it is an exemplary embodiment of the invention.
[0025] In case of doubt on the part of the person skilled in the art, the terms "top" and "bottom" are to be understood as absolute or relative spatial specifications which refer to the orientation of the component in question during its normal use.
[0026] In some embodiments, the container holder is designed as a tray, e.g., as a tray with exactly one recess in its surface.
[0027] In some embodiments, the container holder is wider and / or deeper than it is tall.
[0028] According to the invention, the container holder has at least one partition wall between the first container receptacle and the second container receptacle.
[0029] The partition wall, or sections thereof, may be straight, with one radius of curvature or several radii of curvature (e.g. when considering a cross-section of the partition wall).
[0030] In some embodiments, a partition wall is created by arranging the first container receptacle and the second container receptacle at different levels (e.g., relative to the installation surface of the dialysis device during use); the resulting wall, which delimits the lower container receptacle at least in sections as a side wall, can be understood as a partition wall within the meaning of this description.
[0031] In some embodiments, a partition wall is created by a wall, a bulge or another elevation extending between the first container receptacle and the second container receptacle.
[0032] According to the invention, liquid escaping from a container arranged in the first container receptacle can be guided away from the second container receptacle by the "separating" partition wall or prevented from flowing into it, or vice versa.
[0033] The container receptacle can have exactly two or at least two such partitions—one for the first and one for the second container receptacle. The partition or partitions can have an annular cross-section. They can have a closed cross-section (e.g., in the shape of a ring) or an open cross-section (e.g., in the shape of a U).
[0034] The partition wall, or sections thereof, can be curved. A curved partition wall is one whose height is not constant. The curved shape can be advantageous for saving material.
[0035] In some embodiments, the first container receptacle includes or consists of a collecting tray. Such a collecting tray serves to collect liquid that has leaked from or originates from the first container when it is placed in the first container receptacle.
[0036] In some embodiments, the second container receptacle comprises or consists of a collecting tray.
[0037] Such a collecting tray is used to collect liquid that has leaked out or comes from the second container when it is placed in the second container holder.
[0038] In some embodiments, the container holder comprises a first support surface of the first container receptacle and a second support surface of the second container receptacle.

[0040] According to the invention, the first container receptacle of the container holder comprises an upper edge (during use). This upper edge, or portions thereof, are arranged higher than the support surface, or portions thereof, of the second container receptacle, which serves to support the second container.
[0041] The containers - used, for example, for disinfecting the dialysis machine - stand with their base surfaces (lower sides) on the installation surfaces or in the installation trays of the first and second container holders.
[0042] The containers used in dialysis can have rectangular or circular bases (or cross-sections, also applies below) (alternatively: base areas). The basic shapes of the installation surfaces and / or the collecting trays can be adapted to these shapes.
[0043] In particular, the container holder can have a rectangular first installation surface and / or collecting tray for a container with a rectangular base surface and a circular second installation surface and / or collecting tray for a container with a circular base surface.
[0044] Alternatively, the container holder may have a rectangular first installation surface and / or collecting tray for a container with a rectangular base surface and a rectangular second installation surface and / or collecting tray for a container with a rectangular base surface.
[0045] Further alternatively, the container holder can have a circular first installation surface and / or collecting tray for a container with a circular bottom surface and a circular second installation surface and / or collecting tray for a container with a circular bottom surface, or vice versa.
[0046] In some embodiments, the attachment portion includes one or more openings. The openings may be used to accommodate pins, snap fasteners, or locking pins.

[0049] In some embodiments, the dialysis device comprises a receptacle having at least one pin or a securing pin.
[0050] In some embodiments, the dialysis device receptacle includes at least one push button.
[0051] In some embodiments, the dialysis device (also: dialysis device) is designed as an ultrafiltration device, hemofiltration device, hemodialysis device and / or hemodiafiltration device.
[0052] The dialysis device may optionally comprise or be connected to one or more of the following components: arterial line section, venous line section, arterial connection needle, venous connection needle, arterial patient tube clamp, venous patient tube clamp, blood pump, blood filter, arterial pressure sensor, venous drip chamber, venous pressure sensor, substituate pump, substituate fluid storage device, substituate fluid supply line, pre-dilution addition point, post-dilution addition point, signal processing unit, control line to the blood pump, and / or control line to the substituate pump.
[0053] In some embodiments, the container holder has no moving parts.
[0054] In some embodiments, the container holder is not part of a blood circuit and / or has no flow channels, in particular none with a closed cross-section and / or is not connected to a tube or channel that carries fluid during use and / or has no arterial and / or venous blood chamber and / or has no moving parts through which a fluid flows during use.
[0055] In some embodiments, the container holder does not include both an upper and a lower half or a base body and a cover therefor that are assembled together for use.
[0056] In some embodiments, the container holder is one piece.
[0057] In some embodiments, the container holder is manufactured integrally, for example by injection molding.
[0058] In some embodiments, the container holder has recesses or different thicknesses, which can serve the purpose of saving weight and material.
[0059] In some embodiments, the container holder is made of multiple pieces. For example, it may comprise an injection-molded part, e.g., an upper part, which is connected to or rests on a part made of metal, e.g., a lower part. Such a combination of materials can offer advantages, including the high strength of metal and the cost-effective production of injection-molded parts.
[0060] In some embodiments, the first container receptacle or the second container receptacle is a, preferably flat, installation surface.
[0061] In some embodiments, the first container receptacle or the second container receptacle is only suitable and / or intended to receive or contact a container on one side thereof (preferably on the top side, not also on the bottom side).
[0062] In some embodiments, the container holder, the first container receptacle and / or the second container receptacle have an opening for inserting a container, or a portion thereof, only on one side thereof (preferably on the top side, not also on the bottom side).
[0063] In some embodiments, the container holder has only one opening for inserting a container, or a portion thereof.
[0064] In some embodiments, the container holder has only a trough-like section (such as a collecting trough), in particular for collecting liquids.
[0065] In some embodiments, the first container receptacle and the second container receptacle have installation surfaces of different heights (the height is measured, for example, in use, e.g., from the floor on which the dialysis device carrying the container receptacle stands) for the respective container or floor surfaces of different heights.
[0066] In some embodiments, the container holder does not include freestanding and / or upright columns and / or absorbent material.
[0067] In some embodiments, the container holder is not a disposable and / or modular article.
[0068] In some embodiments, the container holder does not have a lid, in particular a removable or welded lid, and / or two-channel connectors.
[0069] According to the invention, the container holder consists of or comprises a thermoplastic. The thermoplastic can be polyamide-6 or polycaprolactam. The thermoplastic, in particular polyamide-6, can be ball- and / or fiber-reinforced, for example, with glass, carbon, or other materials. The thermoplastic can be media-resistant.
[0070] The receptacle and the fastening section can together enable a snap-in connection. They can enable a self-locking connection, which is particularly angle-dependent. They can have an undercut and / or cause one of these two components to engage with the other.
[0071] The receptacle and the fastening section may together have at least one tapered opening. They may have a mushroom-head lock.
[0072] In some embodiments, the container holder comprises a first container and a second container. Optionally, it does not comprise any additional containers besides these two containers.
[0073] In some embodiments, the first container contains a liquid from the group of acidic solutions, in particular acidic disinfectants. These are characterized by having a pH value of less than 7.
[0074] The acidic solution may contain reducible ions, such as chloride ions.
[0075] The liquid of the first container may comprise a single acid or a mixture of different acids, in particular from the group consisting of hydrochloric acid, acetic acid, citric acid, lactic acid, malic acid.
[0076] The liquid in the first container may be a mixture of citric acid, for example in the form of the monohydrate, malic acid and lactic acid.
[0077] The liquid in the first container may be the disinfectant sold under the brand name Citrosteril by Fresenius Medical Care.
[0078] The container containing this liquid may have a rectangular base (or cross-sections).
[0079] In some embodiments, the second container contains a liquid from the group of oxidizing solutions, in particular oxidizing disinfectants. These are characterized in that at least one component has an oxidizing effect on an acidic solution. Examples of such acidic solutions are mentioned in the preceding sections. The oxidizing solution can contain one or more or all of the substances hypochlorite, peroxide, and peracid.
[0080] The liquid in the second container may be an aqueous solution of sodium hypochlorite, potassium hydroxide and / or sodium hydroxide.
[0081] The liquid in the second container may be the disinfectant sold under the brand name Sporotal by Fresenius Medical Care.
[0082] The fluid of the first and / or second container is optionally not an infusate, a dialysis fluid, a dialysate, an effluent and / or a substituate, or precursors thereof.
[0083] The container containing this liquid may have a circular bottom surface.
[0084] When removing liquids from the containers, uncontrolled leakage of the liquids from the containers may occur, for example, by sloshing, adhering to a dispensing device, or overflowing. This may cause the two liquids to come into contact with each other. This may pose a hazard. The oxidizing agent may react with the acidic solution. Such a reaction can occur as follows, releasing toxic chlorine gas: 2H 3 O + OCl -< + Cl -< -> 3H 2 O + Cl 2
[0085] In some embodiments, the container holder does not have a movable element, in particular relative to one of the support surfaces or container receptacles, in particular no movable fastening section and / or no movable fastening means.
[0086] In some embodiments, the container holder has no handle and / or no grip portion protruding from the rest of the container holder.
[0087] In some embodiments, the container holder does not have any means by which it supports itself directly (i.e. not via the dialysis device) on the floor when it is connected to the dialysis device, in particular no rollers.
[0088] In some embodiments, the container holder does not have a device by which it is in data, signal, fluid and / or energy transmission connection with the dialysis device.
[0089] In some embodiments, the container holder and / or the containers arranged on it are not connected to the dialysis device in a, for example, rigid, fluid transfer connection. In some embodiments, only a fluid transfer connection established via a flexible hose may be provided.
[0090] In some embodiments, the fastening section, which serves to connect the container holder to the receptacle of the dialysis device, is connected to or assigned to - preferably only - one of the container receptacles, which serve to hold a container each. This container receptacle can be the first container receptacle. It can be the largest of all existing container receptacles. It can be a container receptacle which has no recess. It can be the container receptacle which, in the use state, is closer to the receptacle of the dialysis device or is arranged without a gap to the receptacle. This makes it possible to achieve greater stability for arranging comparatively large containers.In addition, it can be ensured that a liquid escaping from one of the containers can drain between the dialysis device and the container holder at least over sections of the container holder, on which the latter preferably has no fastening section, without wetting the housing of the dialysis device.
[0091] In some embodiments, the fastening portion which serves to connect the container holder to the receptacle of the dialysis device is arranged to be connected to a lower or middle portion, but not to an upper portion, of the receptacle.
[0092] In this way, in some embodiments, at least the upper portion of the receptacle protrudes upwards above the fastening portion, above at least one container receptacle, or above the entire container holder. This ensures that fluid escaping from one of the containers only wets the receptacle, but not the housing of the dialysis device or components of the dialysis device (such as connectors, etc.). The receptacle, which is a comparatively small component, can be made of a material that is particularly suitable for contact with escaping fluid.
[0093] In some versions, the width of the container holder is between 30 cm and 50 cm. This allows two containers to be placed side by side on the container holder.
[0094] In some embodiments, the depth of the container holder is between 14 cm and 25 cm, preferably between 17 cm and 20 cm. This allows it to comfortably accommodate the depth of a container.
[0095] In some embodiments, the depth of at least one of the container receptacles (from the bottom to the top edge) is at least 8 cm, preferably 9 cm, 10 cm, 11 cm, or more. This allows, for example, a 1-liter container to be securely stored in the container receptacle without tipping over.
[0096] In some embodiments, the container holder has at least one flat surface with a width of at least 15 cm, preferably at least 17 cm, and a depth of at least 15 cm, preferably at least 17 cm. This allows for convenient accommodation of containers with a capacity of more than one liter.
[0097] Some or all embodiments of the invention may have one, several or all of the advantages mentioned above and / or below.
[0098] One advantage achievable by certain embodiments of the invention is that liquids such as disinfectants that spill or overflow from the containers placed on the container holder do not come into contact with each other. Chemical reactions between them can thus be advantageously avoided. The aforementioned partition wall, the collecting tray, and other features mentioned herein can contribute to this.
[0099] It may also be advantageous that, due to the low arrangement of the holding section on the dialysis machine, its stability is not impaired by the arrangement of the containers, which can be particularly noticeable when the dialysis machine is moved along on wheels.
[0100] Provided partition walls can also provide lateral support for the container placed on the container holder. This can prevent it from tipping over, for example, when the dialysis machine is being moved.
[0101] Due to the movable fastening, it may preferably be possible to arrange the container holder in a space-saving manner for transport, for example on the dialysis machine, or to remove it from it.
[0102] The fastening section for the movable fastening of the container holder, in particular in the form of a manually removable or detachable fastening section, can allow easy cleaning of the container holder and / or the dialysis device.
[0103] The present invention is explained below by way of example with reference to the accompanying drawings, in which like reference numerals designate identical or similar components. In the figures: Fig. 1 shows a container holder according to the invention in a first exemplary embodiment; Fig. 2 shows the container holder according to the invention of the Fig. 1 in a different perspective; Fig. 3 shows a dialysis device according to the invention; Fig. 4a, 4b show the container holder and the receptacle of the previous figures in section in a state of use ( Fig. 4a ) or during its connection to or detachment from the dialysis device; Fig. 5 shows an exemplary embodiment of the container holder according to the invention in a second embodiment; and Fig. 6 shows the container holder of the Fig. 5 in one cut.
[0104] Fig. 1 shows a first embodiment of the container holder 100 according to the invention. It has a first container receptacle 101 for receiving a first container (in Fig. 1 not shown, but see reference numeral 201 in Fig. 3 ) and a second container holder 103 for receiving a second container (in Fig. 1 not shown, but see reference numeral 203 in Fig. 3 ) on.
[0105] The container holder 100 further comprises a fastening section 105 for the movable, here detachable, fastening of the container holder 100 to a dialysis device (in Fig. 1 not shown, but see reference numeral 300 in Fig. 3 ). The fastening section 105 is designed for connection to a receptacle 305 of the dialysis device 300. It serves to detachably connect the container holder 100 to a holding section of the dialysis device 300.
[0106] The first container receptacle 101 is designed as a space surrounded by a partition wall 107 and open at the top, also referred to herein as an interior.
[0107] In any embodiment, the partition wall 107 can be continuous, i.e., closed. Alternatively, several partition walls 107 can be provided, arranged at a distance from one another.
[0108] Partition walls 107 can be provided in particular between the first container receptacle 101 and the second container receptacle 103.
[0109] Partition walls 107 can be arranged in such a way that liquids located on the floor of one of the container receptacles 101, 103 are prevented from flowing into the other container receptacle.
[0110] The room can, as in Fig. 1 Optionally shown, it can be limited at the bottom by a floor section 109. It can also be closed at the bottom by the support surface, so that liquids cannot escape from the space. The floor section 109 can be designed as a collecting tray.
[0111] The bottom section 109 can have on its upper side a first support surface 111 (seen in Fig. 2 ) for placing or receiving the first container 201. The first support surface 111 can be planar or curved. It can be free of elevations. It can have a through-opening with a closure means.
[0112] The second container holder 103 has a top side which is used for setting up or receiving the Fig. 1 The upper side is therefore referred to as the second support surface 113. It can be planar or curved. It can be free of elevations. It can have a through-opening with a closure means.
[0113] The first container receptacle 101 and the second container receptacle 103 are connected to each other by a connecting section 115. The connecting section 115 lies between them. It can seamlessly transition into the second container receptacle 103.
[0114] The detachable connection between the fastening section 105 and the holder 305 is in Fig. 4a and 4b shown in detail.
[0115] The fastening section 105 and / or the receptacle 305 can each be one piece.
[0116] The fastening section 105 and / or the receptacle 305 can each have a length of several centimeters. Due to their length, mechanical loads that may result from the connection between the fastening section 105 and the receptacle 305 are distributed over a correspondingly large area.
[0117] Unlike in Fig. 1 (and Fig. 5 ), a plurality of fastening sections 105 and / or receptacles 305 may be provided.
[0118] Fig. 2 shows the container holder 100 of the Fig. 1 from a different perspective.
[0119] The width of the container holder 100 extends in the right-left direction from Fig. 2 The depth extends (slightly distorted by perspective) from top to bottom in Fig. 2 The thickness of the container holder 100 in the area of the first container receptacle 101 can preferably be between 1 cm and 2 cm.
[0120] Fig. 3 shows a dialysis device 300 according to the invention from the rear in a slight perspective from above.
[0121] The dialysis device 300 optionally has rollers 301, e.g., four rollers. They serve to move the dialysis device 300 and can optionally have a locking device.
[0122] The dialysis device 300 has a holding section on its rear side, on which the receptacle 305 is arranged.
[0123] The stopping section is in the example of Fig. 3 in a bottom area of the dialysis device 300, e.g., slightly above the rollers 301.
[0124] The holding section can optionally be arranged so low that a bottom side 117 of the second container receptacle 103 touches and / or rests on a surface 307 of the dialysis device 300 or its holding section. The latter can advantageously serve to securely and stably arrange the container holder 100 on the dialysis device 300. Furthermore, such support allows the use of correspondingly smaller and more cost-effective components such as the fastening section 105 or the receptacle 305.
[0125] The holding section can serve to attach the rollers 301 to the rest of the dialysis device 300.
[0126] The holding section can be a so-called media rail, i.e., a section that also houses one or more water inlets, one or more gas inlets, and / or one or more power connections. The media rail can be an interface between the hydraulic system and external connections. It can be used to supply water and / or cleaning agents to the dialysis machine, to supply dialysis fluid to the patient (substitution) or to the dialyzer, and to discharge fluid from the dialyzer and steam from the machine.
[0127] How Fig. 3 shows, the container holder 100 can be attached to the holding section of the dialysis device 300 in such a way that only the second container receptacle 103 rests on the holding section and / or is covered by a rear wall 309 of the dialysis device 300 or lies behind it, while the first container receptacle 101 protrudes laterally beyond the dialysis device 300 or its rear wall 309. This can optionally result in other accesses being exposed. These accesses can, for example, be part of the media rail. This can optionally also result in one or more media suction devices, which are arranged on the front of the dialysis device 300 and by means of which the contents can be sucked from the containers into the dialysis device 300 via hose lines, not requiring such long hoses. The lateral offset can optionally also prevent a collision of the container with components on the rear wall of the dialysis device 300.It can optionally allow the containers to be visible and partially accessible from the front of the dialysis device 300 and / or, if necessary, prevent a collision of the partition wall 107 in the folded-up state with the rear wall of the dialysis device 300. This can also provide greater freedom in determining a depth of the first container receptacle 101 running in the transverse direction of the container holder 100. The depth runs in the direction of the in . Fig. 4a The depth of the first container holder 101 can be adjusted as shown in Fig. 3 shown, be greater than the depth of the second container receptacle 103. However, it may also be equal to or less than that.
[0128] Fig. 4a und Fig. 4b show the container holder 100 and the receptacle 305 of the previous figures from the side, in a section through the connecting section 115, the fastening section 105 and the receptacle 305, along the line II of the Fig. 1 , i.e. with a view of the uncut first container shot 101. Containers 201 or 203 are not shown.
[0129] Fig. 4a shows the fastening section 105 and the receptacle 305 in a locked or fully connected state, as it exists in the use state and can therefore optionally be understood as a use state.
[0130] In this case, an end section 305a of the receptacle 305, which may be shaped as a nose, engages in a recess 105a that may be provided extending from an upper side of the fastening section 105. This, or a differently configured force- and / or form-fitting engagement of the receptacle 305 in the fastening section 105, fixes the container holder 100 at least in a direction that lies in the main extension plane of the container holder 100. In Fig. 4a This direction is a right-left direction and is indicated by a double arrow.
[0131] How Fig. 4a As can be seen, the end section 305a of the receptacle 305 can be separated from other sections of the receptacle 305 by a step. It can have a rear side tapered at a radius. It can have a straight front side.
[0132] The end section 305a of the receptacle 305 can be touched or in contact with surfaces of the recess 105a at least on its front side and possibly also on side sections.
[0133] The receptacle 305 can be prepared to be screwed to the holding section of the dialysis device 300. For this purpose, it can have one or more openings, e.g., threaded openings 311. These openings can be through-holes or, as in Fig. 4a As shown in the example, these can be bag openings. Fig. 4a The holder 305 is screwed from its rear side, i.e. from the side facing away from the container holders 101, 103. Other detachable or non-detachable connections between
[0134] Receptacle 305 and holding section are also encompassed by the present invention.
[0135] An angle α between fastening section 105 and receptacle 305 is, for example, between 80° and 100°, approximately 90° or a right angle in the state of use.
[0136] The receptacle 305 can be perpendicular to a mounting plane of the dialysis device 300 and / or to a main extension plane of the container holder 100 in its use state.
[0137] Fig. 4b shows the fastening section 105 and the receptacle 305 in a non-latched or not fully connected state. Fig. 4b does not show the state of use of the container holder 100. Rather, it shows a position of the container holder which it assumes when it is connected to the dialysis device 300 or when it is detached from it.
[0138] The angle α is less than 80°, here approximately 45°. It must be adjusted to the final connection of the container holder 100 to the dialysis device 300. Fig. 4a The angle shown can be enlarged.
[0139] How Fig. 4b As can be seen, the connection of the container holder 100 to the dialysis device 300 or its release from it is carried out by pivoting the container holder 100 in a Fig. 4b direction shown by the double arrow.
[0140] The center of rotation of the pivoting movement mentioned above is, in simplified terms, in the end section 305a, or close to it.
[0141] Fig. 5 shows the container holder 100 according to the invention in a second exemplary embodiment.
[0142] The container holder 100 of the Fig. 5 corresponds to the container holder 100 of the first embodiment with the exception of its fastening section 105. The fastening section 105 is in the example of Fig. 5 unlike the example of Fig. 4a / Fig. 4b not designed to be connected to the receptacle 305 by pivoting. Rather, the fastening section 105 is moved from top to bottom (relative to Fig. 5 ) is connected to the holder 305. To separate it from the holder 305, it must (at least) be moved upwards (relative to Fig. 5 ) The double arrow of the Fig. 5 indicates this in each case.
[0143] How Fig. 5 As shown, the fastening section 105 has at least one opening 105b into which a pin 305b of the receptacle 305 can engage. The opening 105b is designed as an upwardly tapered opening. It can have the shape of an (inverted) keyhole.
[0144] The pin 305b has a widened portion at its end. It is designed, for example, with a mushroom head shape. With this widened portion, it fits through the non-tapered portion of the opening 105b, but not through its tapered portion. In this way, a locking connection between the pin 305b and the opening 105b can be achieved in a known manner.
[0145] The opening 105b can be as in Fig. 5 shown as an example as a through opening, but can also be a blind hole opening.
[0146] Fig. 5 shows four openings 105b. More or fewer openings of this type are also encompassed by the invention. The same applies to the number of pins 305b.
[0147] Fig. 5 further shows an optional opening 105c of the fastening section 105, which is preferably designed as a through-hole. The opening 105c serves to accommodate a pressure pin, a pressure bolt, or a push button 305c, each of which is provided on the device side.
[0148] Unlike the openings 105b (relative to the pins 305b), the opening 105c is not designed to be displaced relative to the push button 305c to separate the push button 305c and the opening 105c. Rather, the opening 105c is intended to prevent the fastening section 105 from being displaced relative to the receptacle 305 as long as the push button 305c extends into or through the opening 105c. Thus, the push button 305c inserted into the opening 105c prevents the fastening section 105 from being inadvertently released from the receptacle 305, for example, by kicking the underside of the container holder 100 with the foot, and causing the container holder to inadvertently detach from the dialysis device 300.
[0149] To release the container holder 100 from the dialysis device 300, the push button 305c must first be pressed, with the aim of pushing it out of the opening 105c—possibly against a resistance that can only be generated, for example, by a spring device. Only when it is disengaged from the opening 105c can the container holder 100 be released from the pins 305b and thus from the dialysis device 300 by sliding it upward.
[0150] Fig. 6 shows the container holder 100 of the Fig. 5 in a section along the line II-II of the Fig. 5 .
[0151] As can be seen, the fastening section 105 continues in a base plate 119, on which the second container holder 103, which was manufactured separately from the base plate 119, is arranged or rests with its underside 117.
[0152] The person skilled in the art will recognize that it is irrelevant for the desired function whether the pins 305b and / or the push button 305c are present on the side of the dialysis device 300 and the corresponding openings 105b and 105c are present on the side of the container holder 100, or vice versa. The same applies to the components 105 and 305 of the Fig. 1 shown embodiment. They can also be present alternatively on the container holder 100 or on the dialysis device 300.
[0153] As can be seen from the figures, the container holder can have sections of different depths, which is not least evident in a plan view, see e.g. Fig. 2 , which is very close to a top view. Bezugszeichenliste
