[0033] FIG. 6-8 illustrate removal and transport of the portable rack and the modules.

[0034] FIG. 9 shows the portable rack with two inserted infusion devices;

[0035] As an introduction, FIG. 1 shows a schematic drawing of an infusion station IS at the bedside of a patient P, for example in a healthcare environment, such as in an intensive care unit (ICU) of a hospital.

[0036] As visible from FIG. 1 and in view of the following figures, the infusion station IS comprises a rack 10 defining a multiplicity of slots 100 to which a multiplicity of infusion devices 2 may be attached. The rack 10, at the slots 100, provides for a mechanical and electrical connection for the infusion devices 2, the rack 10 generally serving as a communication link as well as a power supply such that the infusion devices 2 connected to the rack 10 are interconnected with each other and further are connected to a power supply via the rack 10. As an example, the rack 10 itself does not comprises control device 11. But a control device 11 could be attached to the rack 10 as shown in FIG. 1. The rack 10 stands vertically and the slots 100 extends perpendicularly to the back 31 of the rack 10 such that the infusion devices are horizontally positioned onto the rack. As a consequence, the screen of the infusion devices 2 can be easily seen by a user.

[0037] The rack 10 and the infusion devices 2 arranged thereon are connected to a stand 3 placed at the bedside of a patient P, as visible from FIG. 1. The rack 10 holds the infusion devices 2 connected thereto in an organized fashion, forming a vertical stack of infusion devices 2.

[0038] The infusion devices 2 may be configured as syringe infusion pumps or as volumetric (peristaltic) infusion pumps. In either case, the infusion devices 2 may comprise a housing, an input device for example in the shape of a rotary knob and/or a keypad or the like for inputting data into the respective infusion device 2, for example for programming an infusion operation, and a display for outputting information, for example relating to an ongoing infusion operation.

[0039] The following figures show an embodiment of the portable rack 20 according to the present invention. In contrast to the rack 10 described in FIG. 1, the portable rack 20 is not serving as a communication link but as a power supply only. The power supply is provided such that the infusion devices 2 connected to the portable rack 20 are connected to a power supply via the portable rack 20. The portable rack 20 is protected against short circuits with the modules 2 it holds.

[0040] The portable rack 20 is intended to act as a support mechanism and centralized power supply for two infusion modules 2, in particular when two modules 2 are running on battery and need to be transported. FIG. 2a shows a front view of the portable rack 20 without any attached infusion device 2. FIG. 2b shows the back view of the portable rack 20.

[0041] FIG. 3 shows that two modules 2 are mounted on the portable rack 20. The portable rack 20 is designed to hold and power two modules 2: a volumetric pump or a syringe pump. The upper module 2 is a volumetric pump. The lower module 2 is a syringe pump. With this portable rack 20, the user can carry the modules 2 with the handle 22 or can attach the modules 2 to a pole or rail. For instance, the portable rack 20 can be installed on a pole, rail or bed-rail with a diameter between 16 mm and 40 mm (not shown in the figures).

[0042] FIGS. 4 and 5 illustrate installing the portable rack 20 and the modules 2.

[0043] At first, FIG. 4 illustrates installing the portable rack 20: [0044] 1. To attach the portable rack 20 directly to the pole: push down on the release button 28, slide the screw clamp 27 forward and tighten it. The portable rack 20 can also be attached to a horizontal rail. To do so, the pole clamp 27 must be repositioned vertically. The portable rack 20 can also be placed directly onto a flat surface, such as a tablet, table, cupboard, shelf, nightstand or the patients bed (but not on the floor). To do so, the pole clamp 27 must or should be removed. [0045] 2. Plug the portable rack 20 into the power supply 29 via a cable (not shown in the figures). The wall socket must remain accessible at all times to allow emergency power supply disconnection.

[0046] The technique of the screw clamp 27 bases on a technique or is at least similar to a technique which is for instance described in the patent application DE 10 2015 122 699 A1. The entire content of this patent application is incorporated by reference.

[0047] FIG. 5 now illustrates installing the modules 2 to the portable rack 20.

[0048] With the hands on each side of the module 2, slide the module into the portable rack 20, making sure that you hear it click into place. It is recommended inserting the device 2 into the bottom slot first. The device 2 turns on when it is plugged to the mains power supply. There is no ON/OFF button. Unplug the device to turn it off. The portable rack 20 can connect to and power two modules 2. A correct connection is signaled by an audible click. The rack cannot be configured.

[0049] FIGS. 6 to 8 illustrate removal and transport of the portable rack 20 and the modules 2.

[0050] At first, FIG. 6 illustrates the removal of the modules 2 from the infusion station IS, for instance when moving the module 2 with the patient P. Before transporting the patient P, make sure the modules battery is sufficiently charged. First, remove the module 2 by pressing the blue release button on the back-right corner, and slide the module 2 out of the rack of the infusion station IS. When the module 2 is on, the touchscreen and keypad automatically lock when you press the release button. The module 2 beeps when it switches to battery power supply.

[0051] Install the module 2 in the portable rack 20. With your hands on each side of the module 2, slide the module 2 into the portable rack 20, making sure that you hear it click into place (see FIG. 7). Connect the portable rack 20 to the mains once the patient P has arrived at the destination, and once the patient P is transferred back to bed, re-install the module 2 in the infusion station IS. The module 2 beeps when it switches to the mains power supply. The power status LED lights up green and the battery charge status LED blinks to indicate that the battery is charging.

[0052] Disassembling the portable rack 20 is illustrated in FIG. 8. 1. Remove all the modules 2 from the portable rack 20. 2. Push down on the release button 28 and pull on the screw clamp 28 to release it from the pole or rail.

[0053] FIG. 8 also depicts the position of the handle 22 extending along an axis A following a transversal direction and defining, in the upper side of the portable rack 20, the opening 23, allowing for a user to manipulate and to transport the portable rack 20.

[0054] As it can be further contemplated in FIG. 9, the position of the handle 22 relative to the back 31 of the portable rack 20 is such that, when one or several infusion devices 2—for instance two infusion devices 2—are loaded onto the portable racks slot 100, the back 31 of the portable rack 20 stands essentially vertically. Essential vertical means that portable rack 20 could be slightly tilted. This is achieved by the following features: [0055] the center of gravity (G) of the infusion devices 2 being located in the region of the center of the infusion device preferably essentially at the center of the infusion device 2, [0056] the axis A of the handle 22 being located such that it aligns with the middle of the infusion devices 2 when loaded, and [0057] the negligible weight of the portable rack in regard to the weight of the infusion devices 20.

[0058] As a result, in particular during manual transportation of the loaded portable rack 2, the infusion devices 2 stand horizontally such that their screens can be seen.

[0059] It will be understood that the invention may be embodied in other specific forms without departing from the spirit or central characteristics thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein. Accordingly, features of the above described specific embodiments can be combined with one another. Further, features described in the summary of the invention can be combined with one another. Furthermore, features of the above described specific embodiments and features described in the summary of the invention can be combined with one another.
