The present disclosure relates to a container holder for use with dialysis apparatuses.
Apparatuses for therapeutic apheresis, liver support therapy, oxygenation, peritoneal dialysis, or hemofiltration or hemodialysis are known from practice. For the potential treatment of the patient, they may be connected to containers which contain liquids used in the treatment.
A container holder for a dialysis apparatus encompasses a first container receptacle, which is embodied to position a first container, as well as a second container receptacle for positioning a second container. Optionally, the container holder comprises only the first container receptacle or only the second container receptacle, but no further container receptacles.
In the following, the apparatuses of the aforementioned types will be collectively referred to as dialysis apparatuses.
The container holder comprises a holding section for movably holding the container holder on or at the dialysis apparatus.
The movable holding may optionally be provided as, or ensured by, a folding device, a shifting device, and/or a releasable holding apparatus. A movable holding may therefore be understood in some embodiments also as a releasable holding, in other embodiments it is not releasable.
A movable holding may optionally allow a relative movement between the container holder and the dialysis apparatus.
A releasable holding may optionally be designed such that the container holder may be removable from the dialysis apparatus without using any tools. Preferably, it may be also again arranged to the dialysis apparatus manually, without any tools.
The present disclosure further relates to a dialysis apparatus which comprises a container holder.
The dialysis apparatus encompasses a mounting device which is designed to be movably connected to a holding section of the container holder at a retaining section of the dialysis apparatus.
The apparatus (synonym: a corresponding mechanism, both terms are interchangeable) for folding, shifting or releasing may thereby be provided through corresponding apparatuses at either the dialysis apparatus or at the container holder or at both apparatuses, namely at the dialysis apparatus and at the container holder.
The connection between a main body of the dialysis apparatus and the container holder may be provided on the rear side of the main body, wherein the front side comprises a plurality (i.e., at least two) of operating elements for a treatment. At the front side, there may be arranged e.g., a blood pump, a clamp for a tube which, in use, is blood conveying, and/or holders for a tube which, in use, is blood conveying, and/or for a cassette which, in use, is blood conveying.
In all of the remarks made herein, the use of the expression “may be” or “may have” and so on, is to be understood synonymously with “preferably is” or “preferably has,” and so on respectively, and is intended to illustrate embodiments.
Embodiments may comprise one or several of the features mentioned above and in the following. In this, the features mentioned herein may be, in any combination, the subject of embodiments, unless the person skilled in the art recognizes a specific combination as technically impossible.
Furthermore, embodiments are the subject of the dependent claims.
Whenever numerical words are mentioned herein, the person skilled in the art shall recognize or understand them as indications of numerical lower limits. Unless it leads the person skilled in the art to an evident contradiction, the person skilled in the art shall comprehend the specification for example of “one” as encompassing “at least one”. This understanding is also equally encompassed as the interpretation that a numeric word, for example, “one” may alternatively mean “exactly one”, wherever this is evidently technically possible for the person skilled in the art. Both are encompassed and apply herein to all used numerical words.
Whenever an embodiment is mentioned herein, it is then an exemplary embodiment.
“Top” and “bottom” are indications which, in case of doubt by the person skilled in the art, are to be understood as absolute or relative spatial indications which relate to the orientation of the corresponding component during its intended use.
In some embodiments, the container holder is designed as a tray, e.g., as a tray with exactly one indentation with regard to its surface.
In some embodiments, the container holder is wider and/or deeper than it is high.
In some embodiments, the container holder comprises at least one partition wall between the first container receptacle and the second container receptacle. The partition wall may have the shape of a wall. It may optionally have a different shape than a wall. The partition wall may thus optionally be a separating section. The partition wall is optionally provided.
The partition wall, or sections thereof, may run or extend straight, with one curvature radius or a plurality thereof (e.g., in a cross-section view of the partition wall).
In some embodiments, a partition wall is formed when the first container receptacle and the second container receptacle are arranged on different levels (for example, relative to the base surface of the dialysis apparatus during use). The wall formed in that way, limiting the lower-arranged container receptacle as a side wall at least in section, may be understood as a partition wall in the sense of this description.
In some embodiments, a partition wall is formed by a wall, a bulge or another protrusion extending between the first container receptacle and the second container receptacle.
Due to the partition wall which is arranged to “separate”, liquid that escapes from a container, arranged in the first container receptacle, may be diverted away from the second container receptacle or prevented from entering it, or vice versa.
The container receptacle may comprise exactly two or at least two such partition walls for each the first and the second container receptacle. The partition wall (s) may have an annular form. They may have a closed cross-section (e.g., in a ring-form) or an open cross-section (e.g., in a U-form).
The partition wall, or sections thereof, may be curved. A curved partition wall may be understood as a partition wall with an inconstant height. The curved form may advantageously contribute to saving material.
In some embodiments, the first container receptacle comprises, or is, a drip pan. Such a drip pan serves to collect liquid which has escaped from the first container or originates therefrom, when the container is placed in the first container receptacle.
In some embodiments, the second container receptacle comprises, or is a drip pan. Such a drip pan serves to collect liquid which has escaped from the second container or originates therefrom, when this container is placed in the second container receptacle.
In some embodiments, the container holder encompasses a first base or support surface of the container receptacle and a second base or support surface of the second container receptacle. The first support surface, or sections thereof, which serves for placing the first container, is arranged during use to be lower than the second support surface, or sections thereof, which serves for placing the second container.
In some embodiments, the support surface, or sections thereof, of the first container receptacle and/or the support surface, or sections thereof, of the second container receptacle are arranged during use of the container holder lower than a connecting section, which extends between the first and/or the second container receptacle and connects both container receptacles.
In some embodiments, the first container receptacle of the container holder comprises (during use) an upper edge. This upper edge, or sections thereof, is arranged higher than the support surface, or sections thereof, of the second container receptacle which serves for placing the second container.
The containers—exemplarily used for disinfecting the dialysis apparatus—are placed with their bottom area onto the support surface or in the drip pan of the first and of the second container receptacle.
In this, the containers used during dialysis may comprise rectangular or annular bottom surfaces (or cross-sections, applies also in the following) (alternatively: support surfaces). The basic shape of the support surface and/or of the drip pans may be adapted to these forms.
In particular, the container holder may comprise a rectangular first support surface and/or drip pan for a container having a rectangular bottom area and an annular second support surface and/or drip pan for a container having an annular bottom area.
Alternatively, the container holder may comprise a rectangular first support surface and/or drip pan for a container having a rectangular bottom area and a rectangular second support surface and/or drip pan for a container having a rectangular bottom area.
Further alternatively, the container holder may comprise an annular first support surface and/or drip pan for a container having an annular bottom area and an annular second support surface and/or drip pan for a container having an annular bottom area, or vice versa.

In some embodiments, the dialysis apparatus is an ultrafiltration apparatus, hemofiltration apparatus, hemodialysis apparatus and/or hemodiafiltration apparatus.
The dialysis apparatus may optionally comprise, or be connected to, one or several 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 liquid reservoir, substituate liquid inlet line, pre-dilution addition site, post-dilution addition site, signal processing unit, control line for the blood pump, and/or control line for the substituate pump.
In some embodiments, the container holder comprises no movable parts.
In some embodiments, the container holder is one piece.
In some embodiments, the container holder is integrally manufactured, for example by an injection molding.
In some embodiments, the container holder comprises recesses or different thicknesses, which may serve for saving weight and material.
In some embodiments, the container holder is multi-piece. Thus, it may comprise e.g., a part manufactured by injection molding, e.g., an upper part, which is connected to, or lies on, a part component, e.g., a bottom part e.g., made of metal. Such a combination of material may include advantages which may encompass the high strength of metal and the cost-effective production of injection molding parts.
In some embodiments, the first container receptacle or the second container receptacle is a, preferably flat, support surface.
In some embodiments, the first container receptacle or the second container receptacle is only suitable and/or provided to position or touch a container, on one side thereof (preferably on the top, not also at the bottom).
In some embodiments, the container holder, the first container receptacle and/or the second container receptacle comprises an opening for inserting a container or a section thereof only on one side thereof (preferably on the top, not also at the bottom).
In some embodiments, the container holder comprises only one opening for inserting a container or a section thereof
In some embodiments, the container holder comprises only a tub-like section (e.g., a drip pan), in particular to collect liquid.
In some embodiments, the first and the second container receptacle comprise, for each container, support surfaces of different height, (the height is measured e.g., during use, e.g., from the bottom area or floor on which the dialysis apparatus carrying the container receptacle is placed).
In some embodiments, the container holder comprises no free-standing and/or upright pillars and/or no absorbent material.
In some embodiments, the container holder is not a disposable and/or not a modular article.
In some embodiments, the container holder comprises no cover, in particular no removable or welded cover, and/or no two-channel plug-in connectors.
In some embodiments, the container holder consists of or comprises thermoplastic. The latter may be polyamid-6 or polycaprolactam. The thermoplastic, in particular the polyamid-6, may be ball- and/or fiber-reinforced, e.g., with glass, carbon or other materials. The thermoplastic may be media-resistant.
The mounting device and the holding section may together enable a latching connection. They may enable a self-locking connection, which is in particular angle-dependent. They may comprise undercuts and/or may effect a mesh of one of these two components into the other.
The mounting device and the holding section may together comprise at least one tapering opening. They may comprise a mushroom-head lock.
In some embodiments, the container holder comprises a first and a second container. Optionally, it comprises no additional container besides these two containers.
In some embodiments, the first container comprises a liquid from the group of acidic solutions, in particular the acidic disinfectants. These are characterized in that they have a pH value less than 7.
The acidic solution may contain reducible ions, e.g., chloride-ions.
The liquid of the first container may comprise a single acid or a mixture of different acids, in particular from the group which consists of hydrochloric acid, acetic acid, citric acid, lactic acid, malic acid.
The liquid of the first container may be a mixture of citric acid, e.g., in the form of monohydrate, malic acid and lactic acid.
The liquid of the first container may be the disinfectants, as marketed by Fresenius Medical Care under the brand name Citrosteril.
The container containing this liquid may comprise a rectangular bottom area (or cross-sections).
In some embodiments, the second container comprises a liquid from the group of oxidizing solutions, in particular of the oxidizing disinfectants. These are characterized in that at least one component has an oxidizing effect on an acid-containing solution. Examples for acid-containing solutions are mentioned in the preceding paragraphs. The oxidizing solution may comprise one, several or all of the substances hypochlorite, peroxide, peracid.
The liquid of the second container may be an aqueous solution of sodium hypochlorite, potassium hydroxide and/or sodium hydroxide.
The liquid of the second container may be the disinfectant as marketed by Fresenius Medical Care under the brand name Sporotal.
The liquid of the first and/or second container is optionally no infusate, no dialysis liquid, no dialysate, no effluent and/or no substituate, or no precursor thereof.
The container containing this liquid may comprise an annular bottom area.
When removing the liquid from the containers, an uncontrolled leakage of the liquids out of the containers may occur, e.g., through sloshing or spilling out, adhesion of liquid to the removal device, overflowing. Hence, the two liquids may come into contact with each other. This may lead to dangers. The oxidizing agent may react with the acidic solution. Such a reaction may occur as follows, wherein toxicated chlorine gas is released:
2H30++OCl−+Cl−->3H20+Cl2
In some embodiments, the container holder comprises no movable element, in particular relative to one of the support surfaces or container receptacles, in particular no movable holding section and/or no movable holding element.
In some embodiments, the container holder comprises no handle and/or no grip section protruding from the other parts of the container holder.
In some embodiments, the container holder comprises no device with which it supports itself directly (i.e. not via the dialysis apparatus) on the ground or floor, when it is connected to the dialysis apparatus. It comprises in particular no rollers.
In some embodiments, the container holder comprises no device with which it is in data/signal/fluid and/or energy transmission communication with the dialysis apparatus.
In some embodiments, the container holder and/or the container arranged thereon is not in a, for example, rigid fluid communication with the dialysis apparatus. In some embodiments, only one fluid transmission communication may be provided which is establishable or producible by or through or over a flexible tube may be provided.
In some embodiments, the holding section, which serves for connecting the container holder to the mounting device of the dialysis apparatus, is connected to or associated with,—preferably only—one of the container receptacles for positioning a respective container.
This container receptacle may be the first container receptacle. It may be the largest of all available container receptacles. It may be a container receptacle comprising no recess. It may be the container receptacle which is, during use, closest to the mounting device of the dialysis apparatus or arranged with no gap to the mounting device. As a result, a higher stability for arranging comparatively large containers may be achieved in each case. In addition, it may be ensured that liquid leaking from one of the containers may escape between dialysis apparatus and container holder, at least over sections of the container holder at which the latter has no holding sections, without wetting the dialysis apparatus.
In some embodiments, the holding section which serves for connecting the container holder to the mounting device of the dialysis apparatus, is arranged to be connected to a lower or middle section, but not to an upper section, of the mounting device.
In this way, in some embodiments, at least the upper section of the mounting device protrudes upwards above the holding section, above at least one container receptacle or above the entire container holder. As a result, it may be ensured that a liquid leaking from one of the containers wets only the mounting device but not the housing of the dialysis apparatus or components thereof (like connections, etc.). The mounting device, which is comparatively a small component, may be manufactured from material particularly suitable for contact with leaking liquid.
In some embodiments, the width of the container holder is between 30 cm and 50 cm. This enables arranging two containers next to each other on the container holder.
In some embodiments, the depth of the container holder is between 14 cm and 25 cm, preferably between 17 cm and 20 cm. This enables receiving the depth of a container in a comfortable manner.
In some embodiments, the depth of at least one of the container receptacles (from ground to the upper edge) is at least 8 cm, preferably 9 cm, 10 cm, 11 cm or more. This enables the container holder to keep e.g., a 1-liter container in the container receptacle in a tilt-proof manner.
In some embodiments, the container holder comprises at least one plane surface having a width of at least 15 cm, preferably at least 17 cm, and a depth of at least 15 cm, preferably 17 cm. This enables the container holder to comfortably position containers having a capacity of more than one liter.
Some or all embodiments may comprise one, several or all of the above-mentioned and/or the following advantages.
One advantage achievable by certain embodiments is that, liquids, like e.g., disinfectants, which spill or overflow from the container arranged on the container holder do not come into contact with each other. Chemical reactions between them may thus be advantageously prevented. The aforementioned partition wall, the drip pan and further features mentioned herein may contribute thereto.
A further advantage may be that due to the low arrangement of the retaining section at the dialysis apparatus, the stability of said arrangement is not impaired due to arranging or placing the containers. One notices how comfortable this may be when rolling the dialysis apparatus.
The provided partition walls may offer a lateral support to the containers placed on the container holder. These containers may hereby be prevented from falling, e.g., when rolling the dialysis apparatus.
Due to the movable holding, it may preferably be possible to arrange the container holder, in a space-saving manner, e.g., for its transport—for example at the dialysis apparatus—or to remove it therefrom.
The holding section for the movable holding of the container holder, in particular being a manually removable or releasable holding section, may enable an easy cleaning of the container holder and/or of the dialysis apparatus.
The movably fixed container holder may also comprise only one support surface. All of the explanations which relate to possible embodiments of the container holder and/or of the holding of the container holder at the dialysis apparatus, also apply to embodiments in which the container holder comprises only one support surface (e.g., only the first or only the second) and/or only one container receptacle (e.g., only the first or only the second).
The container holder comprises in some embodiments only one container receptacle (e.g., only the first or only the second), which however is designed with more than one support surface and/or designed for positioning or placing more than one container.
In the following, the present invention is exemplarily explained with regard to the accompanying drawing in which identical reference numerals refer to the same or similar elements. Wherein:
The container holder 100 further comprises a holding section 105 for holding the container holder 100 to the dialysis apparatus (not shown in
The first container receptacle 101 is designed as an area surrounded by a partition wall 107 and open to the top, herein also referred to as an interior.
The partition wall 107 may in each embodiment be circumferential, i.e. closed. Alternatively, there may be a plurality of partition walls 107 provided, which are arranged apart from each other.
Partition walls 107 may in particular be provided between the first container receptacle 101 and the second container receptacle 103.
Partition walls 107 may extend in such way that liquids present on the bottom of one of the container receptacles 101, 103, are prevented from flowing or leaking into the other container receptacle, respectively.
Said area may, as optionally shown in
The bottom section 109 may comprise at its upper side a first support surface 111 (as seen in
The second container receptacle 103 comprises an upper side which serves for placing the second container 203, not shown in
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 is placed between them. It may extend or pass seamlessly into the second container receptacle 103.
The releasable connection between the holding section 105 and the mounting device 305 is shown in detail in
The holding section 105 and/or the mounting device 305 may each be one piece.
The holding section 105 and/or the mounting device 305 may each have a length of several centimeters. Due to their lengths, mechanical stress, which may result from the connection of the holding section 105 to mounting device 305, is distributed to a correspondingly large area.
Unlike what is shown in
The width of the container holder 100 extends in the right-left direction of
The dialysis apparatus 300 optionally comprises rollers 301, e.g., four. They serve for moving the dialysis apparatus 300 and may optionally comprise a blocking device.
The dialysis apparatus 300 comprises at its rear side a retaining section at which the mounting device 305 is arranged.
The retaining section is placed in the example of
The retaining section may optionally be so low that a bottom side 117 of the second container receptacle 103 touches a surface 307 of the dialysis apparatus 300 or its retaining section and/or supports itself thereon. The retaining section may advantageously serve for the secure and stable arrangement of the container holder 100 at the dialysis apparatus 300. In addition, such a support allows the use of correspondingly small-dimensioned and cost-effective components such as holding section 105 or mounting device 305.
The retaining section may serve for holding the rollers 301 to the other parts of the dialysis apparatus 300.
The retaining section may be a so-called supply rail, for example a section, at which one or more water inlets, one or more gas inlets, and/or one or more connections for a power supply are located. The supply rail may be an interface between the hydraulic system and external connections. It may have the function of introducing water and/or cleaning agents into the dialysis apparatus, conveying dialysis liquid to the patient (substitution) or to the dialyzer and discharging liquid from the dialyzer as well as steam from the machine.
As shown in
In this, the end-side section 305a of the mounting device 305, which may be formed as a lug, engages in a recess 105a, which may be provided starting from an upper side of the holding section 105. This, or a differently designed, force-closure, and/or form-fit closure engagement of the mounting device 305 in the holding section 105 determines the container holder 100 at least in one direction which lies in the main extension plane of the container holder 100. In
As is seen in
The end-side section 305a of the mounting device 305 may be touched by or in contact with the respective surfaces of the recess 105a, at least at its end face and possibly at its side sections too.
The mounting device 305 may be prepared to be screwed to the retaining section of the dialysis apparatus 300. For this purpose, it may comprise one or several openings, e.g., thread openings 311. These openings may be through-openings or, as exemplarily shown in
An angle α between holding section 105 and mounting device 305 is, during use, e.g., between 80° and 100°, approximately 90° or a right angle.
The mounting device 305 may be perpendicular to a base plane of the dialysis apparatus 300 and/or to a main extension plane of the container holder 100 during use thereof.
The angle α is less than 80°, here approximately 45°. It needs to be enlarged (up) to the angular dimension or extent shown in
As is seen in
The rotation center of the aforementioned pivotal movement lies, for simplicity, in the end-side section 305a, or near thereto.
The container holder 100 of
As shown in
The pin 305b comprises a widening at its end side. It is exemplarily embodied having the shape of a mushroom head. Said widening fits through the non-tapered section of the opening 105b, but not through the tapered section thereof. In this way, a locking between pin 305b and opening 105b is achieved in a known manner.
The opening 105b may be designed as a through-opening as exemplarily shown in
Unlike the openings 105b (relative to the pins 305b), the opening 105c is not designed to be movable relative to the push button 305c in order to separate the push button 305c from the opening 105c. In fact, the opening 105c should prevent a shifting of the holding section 105 relative to the mounting device 305 as long as the push button 305c extends into the opening 105c. Hence, the push button 305c stuck through the opening 105c prevents an unintentional release of the holding section 105 from the mounting device 305, for example due to a foot kick against the bottom side of the container holder 100, and prevents that the latter is unintentionally released from the dialysis apparatus 300.
In order to release the container holder 100 from the dialysis apparatus 300, the push button 305c has to be initially pushed, possibly against a resistance which may only be generated by a spring device, for example only so that it is pushed out of the opening 105c. Only when said push button 305c is not engaged with the opening 105c, the container holder 100 may be released from the pins 305b and thus from the dialysis apparatus 300 by shifting.
As can be seen, the holding section 105 continues in a bottom plate 119 on which the second container receptacle 103, which was manufactured separately from the bottom plate 119, is arranged or rests with its bottom side 117.
The person skilled in the art recognizes that it is irrelevant for the function intended whether the pins 305b and/or the push button 305c are arranged on the side of the dialysis apparatus 300 and the corresponding openings 105b and 105c, respectively, are arranged on the side of the container holder 100, or vice versa. The same applies for the components 105 and 305 of the embodiments shown in
As can be seen in the figures, the container holder may comprise sections with different depths being recognizable especially in a top view, see e.g.,
