[0002] Medical device

[0003] FIELD OF THE INVENTION

[0004] The present invention includes a medical device, a medical accessory, a medical system and a medical method for optimized operation of a medical device.

[0005] BACKGROUND OF THE INVENTION

[0006] Medical devices, in particular volumetric pumps or syringe pumps, are known in the prior art and are used to treat a patient and, in particular, to administer medication to the patient in an automated manner. Medical accessories, in particular disposable medical items such as syringes or infusion tubes connected to infusion bags, are inserted into the medical device, which then delivers the medication or medical solution contained in the accessory, for example a syringe for a syringe pump or a disposable infusion item, e.g., an infusion bag, to the patient in a controlled manner. In particular, the actuator and / or pump system present in the medical device is used, which can be controlled by a corresponding control device.

[0007] For example, a medication or other medical solution, such as saline, can be provided in a medical syringe or IV bag. These accessories containing the medication or medical solution can then be inserted into the medical device, and the actuator that operates the syringe or the pump that operates the IV line is then controlled to deliver the desired amount of solution to the patient.

[0008] A variety of such medical devices and associated accessories are known in the prior art.

[0009] However, in everyday medical practice and, where appropriate, in home use, there is generally the challenge of ensuring that the correct medication or medical solution reaches the patient via the desired access, in the desired quantity and at the desired time when using multiple medical devices, and that the medical system, comprising the medical device and the medical accessory, is set up in such a way that confusion or other accidental misuse is excluded as far as possible.

[0010] In practice, clinical staff usually selects an accessory pre-loaded with medical solution and, if necessary, medication, or loads it with solution and, if necessary, medication themselves, and then inserts the loaded accessory into the medical device. If necessary, the selected accessory can be selected and confirmed using a graphical user interface on the medical device. More modern systems have a corresponding network interface and may communicate with an external control unit.

[0011] This is particularly relevant when medical systems, for example in intensive care, comprise a multitude of medical devices for delivering a variety of different medications and solutions to the patient at the same time, possibly via a variety of access points. In this case, a multitude of medical tubes can surround the patient, and safety against errors during connection by medical personnel can be compromised. If the wrong medication is administered, or if the wrong flow rate is selected for the medical device, this can have fatal consequences for the patient. In particular, administering medication via the wrong patient access can be immediately highly critical, or - especially with low flow rates set - any existing alarm that would detect an insufficient administration of medication or medical solution can only be triggered late.Mixing of possibly incompatible medications and / or solutions can also occur due to a lack of overview of the routing of various accessories and medical devices.

[0012] Currently, the identification of suitable accessories is carried out manually and in particular by visually and manually tracking the tube from the medical device to the patient access point. Various solutions are known in the prior art, which in particular provide for marking the accessories in order to prevent confusion when equipping the medical device with the accessory as far as possible. For example, document WO 23280455 A1 discloses a disposable medical article, in particular a medical tube or a medical sliding clamp, for use on or in a medical device, wherein the disposable medical article comprises at least one integrated marking as an identification feature. The at least one marking is provided on a predefined section of the disposable article, for example with a color.

[0013] Document EP 4205779 A1 discloses an infusion pump for detecting the color of a tube clamp using IR markers.

[0014] However, the current state-of-the-art solutions result in increased workload for nursing staff, as they have to laboriously trace the line routing manually. Even the use of color-coded infusion lines can only provide limited clarity, particularly since there isn't a sufficiently large number of different colors available to distinguish all lines in a larger medical infusion system.

[0015] It remains problematic, particularly with regard to use in a dark or largely unlit environment, to avoid errors in the connection and assignment of accessories and medical devices.

[0016] The document WO 2013 074717 A1 discloses an illuminated hose set.

[0017] However, the accessories are mostly disposable items that are disposed of after use.

[0018] US Patent No. 9,308,323 B2 also discusses various approaches for illuminating medical tubing, including optically active coatings, electroluminescent wires, LEDs at various locations along the tubing, and integrated optical fibers. However, this requires custom-manufactured disposable devices or increases the complexity of installation and maintenance.

[0019] US Patent No. 11,221,440 B2 describes a lighting system in which the light source is mounted externally and positioned near the drip chamber as a separate device, along with the controller. This arrangement presents several problems, including increased complexity in installation and maintenance, as well as potential difficulties in precisely aligning the light source to the areas to be illuminated.

[0020] SUMMARY OF THE INVENTION

[0021] It is an object underlying the invention to overcome the above-mentioned and other disadvantages. A further object underlying the invention is to increase safety during the intended connection of medical solutions and, where appropriate, accessories containing medication into a medical device and, in particular, to ensure that the respective accessory is assigned to the correct medical device for its intended purpose. Furthermore, it is an object underlying the invention to facilitate the intended adjustment of the medical device, in particular with regard to the delivery of medical solution and, where appropriate, medication contained in the accessory to the patient. It is also an object underlying the invention to further increase safety and efficiency during the use of medical pump systems and accessories.

[0022] These and other problems are solved by the subject matter of the appended independent claims.

[0023] DETAILED DESCRIPTION OF THE INVENTION

[0024] The above objects are achieved according to the invention by a medical device, a medical accessory, a medical system, a medical method and a computer-readable storage medium according to the appended claims.

[0025] Preferred embodiments can be taken from the dependent claims and further from the following description, particularly including various embodiments as covered and described in the appended claims.

[0026] Those skilled in the art will understand that each embodiment explained in the following description is covered and encompassed by the subject matter of the appended claims. The embodiments, features, and combinations of features described in connection with the invention, as well as the combinations of features specified in the appended claims, but also each combination of features mentioned and described in connection with the embodiments, are at least considered to be derivable by those skilled in the art.

[0027] In particular, each feature and each combination of features in the embodiments described here may, for example, be claimed in a different combination, in particular in a different claim category, since the person skilled in the art will recognize that each individual combination of the features mentioned here is suitable for contributing to solving the underlying problem.

[0028] Furthermore, each feature and combination of features in the claims and in the description below may be used and claimed independently of the respective claimed subject matter, independently of claim dependencies and cross-references, and independently of the claim category in which the feature is claimed. For example, any combination selected from one or more claims may include one or more of the embodiments described below and / or the accompanying figures.

[0029] Within the present application, terms such as "side," "rear," "front," "top," "bottom," "opposite," "inside," "outside," or similar, as used herein, refer to the position of a first object relative to another object. Preferably, they refer to the relative position of a respective part or object with respect to its position when fully assembled for its intended use.

[0030] It will be readily appreciated by a person skilled in the art that a feature, embodiment, effect, or advantage described herein in connection with the inventive medical device may also be a feature, embodiment, effect, or advantage of the inventive method, the inventive accessory, the medical system, and / or the computer-readable storage medium, and vice versa.

[0031] The objects underlying the invention are achieved in a first aspect by a medical device, in particular a medical pump according to the appended claims. The medical device can in particular be a volumetric pump, such as an infusion pump, or a syringe pump, for example a syringe pump. The present invention achieves improved visibility and identification of the tubing through the specific positioning of the illumination source. In particular, the illumination in a viewing area, at the inlet, at the outlet, or at the inlet and outlet of the tubing from the medical device enables targeted illumination of the tubing both at the inlet and optionally additionally or alternatively at the outlet from the device, which facilitates the handling and monitoring of the tubing.

[0032] Furthermore, by recognizing the accessory, the present invention advantageously achieves improved identification and management of medications and accessories, as well as visual support for handling tubing. The control unit automatically adjusts the illumination to the detected accessory, enabling dynamic and context-dependent adjustment of the lighting.

[0033] The device according to the invention comprises a receptacle or a connector for a medical accessory. The connector is configured such that the medical accessory can be inserted, in particular connected and / or coupled. In this case, the entire accessory or only a portion of it can be inserted into the medical device.

[0034] The medical accessory comprises a hose line or is connectable to such a hose line. Those skilled in the art are familiar with such medical accessories and know that they are available on the market in various configurations and can be used in the device according to the present invention. Such an accessory can be one-piece and in particular already comprise the hose line, or can be designed to be connectable to a hose line. The hose line can, for example, be connected to the accessory or plugged on. The device according to the invention further comprises an illumination source for illuminating a part of a hose line comprised and / or connected by the accessory in a field of view.

[0035] The term "field of view" as used herein preferably refers to the perception of a user, in particular medical personnel, who are using the medical device as intended or monitoring its intended use. The field of view is preferably an area that is visible to the user when the device is being used as intended, i.e., preferably with a disposable article inserted. In other words, a field of view is visible to a user even when the receptacle or connection for inserting the accessory article is closed, for example, by a protective or sealing flap.The term "visual area", as used herein, preferably refers to the area of ​​the hose line that is located either at the inlet, i.e. in the visual area in the immediate vicinity of the entry point, or at the outlet, i.e. in the visual area in the immediate vicinity of the exit point of the hose line into or out of the medical device. It is also possible for both the inlet and outlet areas of the hose line to be illuminated. In this case, a person skilled in the art will understand that the term "visual area" refers to both the inlet and the exit of the hose line into or out of the medical device, and that the hose area is illuminated both at the inlet, i.e. in the visual area in the immediate vicinity of the entry point, and at the exit, i.e. in the visual area in the immediate vicinity of the exit point of the hose line into or out of the medical device.

[0036] Illuminating these entry and exit points improves visibility and handling of the tubing, making it easier to monitor and operate the medical device.

[0037] The terms “inlet” and “outlet,” as used herein, preferably refer to the tubing in relation to the medical device in the immediate area of ​​entry into or exit from the device. In other words, the “inlet” is preferably the area visible to the user immediately around the point at which the tubing enters the medical device. This is where the tubing begins to lead into the interior of the device, for example to transport liquids or medications. Accordingly, the “outlet” is preferably the area visible to the user immediately around the point at which the tubing leaves the medical device. This is where the tubing ends after being guided through the device and exits back out to carry the transported liquids or medications.

[0038] The present invention advantageously allows the user, in particular medical personnel, to reliably and quickly verify, by simple visual inspection, that the connection of medical solutions and, if applicable, medications contained in the accessory is in accordance with its intended use in a medical device. In particular, it can easily be ensured that the respective accessory is assigned to the correct medical device.

[0039] The illumination source advantageously illuminates a portion of a tubing line, which is either connected to or part of an accessory, in a visible field of view accessible to the user. This makes it easier to identify and assign a medication or medical solution contained in the accessory, as well as the therapy planned for the patient.

[0040] It is particularly advantageous that the course and / or connection of hose lines, in particular infusion lines, can be better understood by means of an illumination signal, in particular a light signal.

[0041] The illumination source, such as a light source such as a lamp, ensures that the tubing is illuminated in specific areas, particularly in the user's field of vision. The light spreads through an infusion line, for example, and can emerge continuously or at specially designated locations due to scattering or similar physical effects. This makes it possible to easily trace the course of the individual tubing using the illumination signals.

[0042] In an advantageous and preferred embodiment of the medical device according to the present invention, the illumination source is a light source. The light source is preferably selected from the group comprising LEDs and lasers. This particularly advantageously ensures that the selected light source, in particular from the group of LEDs and lasers, enables the medical device according to the present invention to provide precise and effective illumination. LEDs and lasers are characterized by their precise controllability, relatively low cost, low energy consumption, and their ability to specifically direct the light, which leads to improved performance and adaptability of the device.

[0043] Alternatively, other illumination sources can also be used according to the invention. For example, instead of light, an alternating electric field can be used and coupled into the tubing. The illumination signal can then be generated based on electroluminescence effects. Furthermore, electrical currents can also be coupled into the infusion line as an illumination medium, generated by a power source as the illumination source. The light signal is then generated, for example, by emission at semiconductor junctions. For this purpose, the device according to the invention can comprise a suitable illumination source, for example, organic light-emitting diodes.

[0044] In an advantageous and preferred embodiment of the medical device according to the present invention, the medical device comprises a guide for the hose line. Such a guide is present in most common medical devices of the prior art in order to fix the accessory article, or the enclosed and / or connected hose line, as intended. The illumination source can advantageously be attached particularly easily in the region of the hose line guide. In one embodiment, a first illumination source is arranged in the region of the hose line guide within the medical device, i.e. in an area where the article is inserted, such that the viewing area of ​​an exit of the hose line from the medical device is illuminated in order to illuminate the hose line outside the medical device.Additionally or alternatively, a second illumination source is arranged in the region of the tubing guide within the medical device, in a region of insertion of the article, such that the viewing area of ​​an entry of the tubing into the medical device is illuminated in order to illuminate the tubing outside the medical device.

[0045] The terms "outlet" and "inlet," as used herein, preferably refer to regions of the medical device that are related to a designated flow direction (F) of a medication or medical solution provided in the medical accessory. In other words, the outlet of a tubing in a medical device is the region at which a medication or medical solution provided in the medical accessory exits or flows out of the tubing. Correspondingly, the inlet of a tubing in a medical device is the region at which a medication or medical solution provided in the medical accessory enters or flows into the tubing.

[0046] For better orientation, in one embodiment, the medical device can have illumination contours. Such illumination contours can advantageously facilitate the coupling of an illumination signal into the tubing. Simultaneously or alternatively, illumination contours can be designed as illumination guide contours, which advantageously serve to guide the illumination to a coupling point of the illumination signal into the tubing.

[0047] In an advantageous and preferred embodiment of the medical device according to the present invention, the illumination source comprises one or more light sources. The one or more light sources are preferably designed to generate light of different wavelengths. In other words, the light source can generate light of different colors. In particular, the light source can comprise light sources of different colors for this purpose. In particular, the light source can comprise LEDs of different colors, RGB LEDs, or the like. This light source, in particular LEDs, can advantageously be arranged on a single or multiple circuit boards. In such arrangements, the light source can advantageously emit different colors, which can then each be related to the type of medication administered through the tubing, based on content and / or therapy regimen. Alternatively, the selection of the illumination, in particularThe color can be based on the detection of the disposable item, for example, using a sensor of a detection unit for detecting the accessory item and / or for classifying and / or categorizing the accessory item. In other words, depending on the detected accessory item, different colors can be output, each of which can be related to the type of accessory item or, for example, a marker attached to it.

[0048] This makes it easy to assign the medication, based on content and / or therapy regimen, to the medical device based on its color, thus advantageously reducing the risk of confusion or the likelihood of incorrect connection.

[0049] Advantageously, the illumination color can be assigned to the settings in a medication database. This can be provided by the manufacturer in a system according to the invention and / or can be adjustable by a user.

[0050] A selected or predetermined color can be assigned to a medication group.

[0051] For better identification, a medical device according to the present invention may comprise a display element, e.g., on a user interface, such as a separate illuminated display, the entire display, or parts of the user interface shown on the display, which is configured to provide a signal in the same color as the accessory, a marker of the accessory, and / or the illumination signal. In a further embodiment, the medical device according to the present invention may be configured such that a color pattern of alternating colors can be provided as an illumination signal to signal their association.

[0052] In an advantageous and preferred embodiment of the medical device according to the present invention, the medical device comprises a detection unit with a sensor, in particular a touch sensor. Such a sensor can be configured to detect touch by the user. For example, the sensor can be designed such that touching of the tubing can be detected via electrical effects, for example a change in potential, the occurrence or change of leakage currents, or optical effects, for example back reflections of the illumination signal. Such a touch signal can be used as a control signal, for example for switching the illumination on or off by the medical device, in particular by a control unit of the medical device.Furthermore, such sensor information from the detection of touches can also be transmitted to the control unit of the medical device, e.g., the volumetric pump. Additionally or alternatively, the sensor can also be used to detect and, in particular, classify or categorize an accessory. This allows, in particular, the disposable item and / or a portion of a tubing encompassed by and / or connected to the accessory to be illuminated in a field of view based on the detected and thus identified accessory.

[0053] The control unit of a medical device according to the present invention can be configured to change parameters of the medical device based on such control signals. In other words, various parameters of the medical device can then be adjusted by touching the tubing. Based on detection of the user touching the accessory, the lighting or other parameters and control sequences in the medical device can then be controlled. For example, a nurse can orientate themselves more quickly in a tangle of multiple infusion lines and trace the route of a selected line if the tubing touched by the nurse is illuminated and thus visible from the other lines.

[0054] In an advantageous and preferred embodiment of the medical device according to the present invention, the medical device comprises a light switch, in particular a prism. Using such a light switch, the illumination signal from the illumination source can be advantageously directed and / or focused, and for example, bundled, or illuminate the tubing in a point-like manner. The illumination source can also couple the illumination signal into the tubing or tubing material using such a light switch. For this purpose, tubing suitable for this purpose is advantageously usually transparent or translucent, usually made of colorless plastic. The illumination source, in particular the light source, thus advantageously couples the illumination signal into the transparent infusion line by means of the light switch. This can be done, for example,This can advantageously be done via a typical, cylindrical diameter of the casing of such a hose. For this purpose, a device according to the invention can comprise a light switch, in particular a prism, which has a favorable angle of incidence of the light relative to the hose for light input.

[0055] A medical device according to the present invention can further comprise an actuating means for, preferably manually, switching the illumination source on and / or off. In the simplest case, the device comprises an on / off button by means of which the illumination can be switched on and off, for example, by interrupting the power supply to the illumination source. This allows the user to activate or deactivate an illumination signal. In a further embodiment, the medical device according to the invention can comprise a user interface for activating or deactivating the illumination signal, e.g., a touchscreen, or other intended actuating means, or other operating elements already necessary for operating the pump, e.g., a syringe holder, an opening mechanism for a front flap, a positioning contour for the accessory, etc.

[0056] A medical device according to the present invention can further comprise a detection unit for detecting an accessory. In particular, such a detection unit can have a sensor, for example a pump sensor, which is configured to detect at least one marker of the medical accessory, in particular one that is matched to the detection unit. Such a marker can be attached to the accessory by a user and connected to the accessory detachably or permanently, or can be provided as an integrated marker at the factory. Such a marker is provided as an identification feature of the inserted or connected accessory. A control unit of the medical device can be configured to identify the accessory based on the detected identification feature and / or to determine a position of the accessory relative to the detection unit.Such a feature may be provided in different ways and may, for example, be a colored feature, e.g. a colored hose clamp.

[0057] The objects underlying the invention are achieved in a second aspect by a medical accessory. A medical accessory according to the present invention is, in particular, a disposable article. A medical accessory according to the present invention comprises, at least in sections, a hollow body, for example a hose line or a hose line section. A medical accessory according to the present invention is designed for insertion, enclosing, and / or coupling into or to a medical device, wherein the medical device is preferably a medical device according to the present invention.

[0058] The medical accessory can, in particular, be a disposable medical article, such as a syringe, a medical tube, an infusion bag with a tubing line, or an infusion bag designed for connection to a tubing line. The medical accessory can therefore comprise a tubing line or be connectable to a tubing line.

[0059] In an advantageous and preferred embodiment of the medical accessory according to the present invention, the accessory comprises an optical waveguide and / or a light reflection means. This allows the accessory, and in particular a portion of a tubing encompassed and / or connected by the accessory, to be particularly advantageously illuminated in a field of view. Alternatively, the medical accessory according to the present invention can comprise a light-guiding element that is attached and / or machined onto the tubing. This is preferably configured to achieve advantageous coupling of the illumination signal, in particular the light.

[0060] In an advantageous and preferred embodiment of the medical accessory according to the present invention, the medical accessory comprises an illumination source. An accessory with such a separate illumination source in addition to or alternatively to an illumination source of a medical device according to the first aspect of the invention is advantageously used to illuminate a part of a hose line encompassed and / or connected by the accessory in a field of vision. In other words, the accessory itself can also have an illumination source and illuminate itself. It is immediately apparent here that in a system according to the invention, the medical device and the accessory each advantageously have an illumination source. Thus, following insertion of the accessory into a medical device, e.g.A color match of the two illuminations makes correct assignment significantly easier. In this respect, the person skilled in the art will immediately recognize that the illumination source of the accessory according to the invention can have the same properties and features as an illumination source of the device according to the invention according to the first aspect of the invention. Thus, if, for example, an illumination source of the device according to the invention is described herein as a light source, preferably LEDs, lasers or the like, these features are also possible embodiments of the illumination source of the accessory according to the invention. In particular, the illuminescence signal can be generated based on electroluminescence effects. Electrical currents can also be coupled into the hose line. The illuminescence signal can be generated, for example, by emission at semiconductor junctions, for example with organic light-emitting diodes.

[0061] In one embodiment, the medical accessory comprises a light guide along a casing portion of the accessory. The illumination effect can thus be advantageously generated along the casing portion, in particular along the tubing. For this purpose, the accessory, in particular in such a casing portion, can be provided with a material selected for this purpose, for example, with regard to fluorescence properties.

[0062] The objects underlying the invention are achieved in a third aspect by a medical system comprising at least one medical device, preferably according to the first aspect of the invention, and at least one accessory, preferably according to the second aspect of the invention. The system according to the invention further comprises a storage unit with a medication database in which data on medications are stored. An accessory article database is preferably stored in the storage unit, in which data on at least two different accessories are stored. The control unit of the system according to the invention is provided and adapted to illuminate a part of a hose line encompassed and / or connected by the accessory in a field of view on the basis of the detected and thus identified accessory. In other words, depending on orIn relation to the disposable article, a part of a hose line encompassed and / or connected by the accessory article may be illuminated in a field of view.

[0063] Particularly advantageously, the system according to the invention is also capable of filtering and / or limiting a medication selection option in the medication database and / or filtering and / or limiting a selection option for another accessory item. The system according to the invention can be configured to use the data of stored medications, but also to use stored therapy regimens for individual medications and / or medical solutions, or even to use stored therapy regimens for a combination of different medications. Thus, even if the system comprises a plurality of medical devices and / or medical accessories, a clear assignment of medication and / or therapy data from the medication database to the medical devices and / or medical accessories is possible.

[0064] Particularly in embodiments in which the system according to the invention comprises a medical device according to the first aspect of the invention and / or in embodiments in which the system according to the invention comprises a medical accessory according to the second aspect of the invention, the control unit of the system according to the invention can, based on the detected and thus identified accessory, illuminate a portion of a hose line encompassed and / or connected by the accessory in a field of view. This can advantageously be achieved by an illumination source of the medical device or optionally or additionally by an illumination source of the accessory. The system according to the invention thus achieves recognition of the accessory and is easily controllable thanks to the illumination signals provided.Furthermore, the system can be configured in such a way that it can suggest a therapy or a medication, for example also based on a recognition of an accessory item if this and / or the device according to the invention is configured and provided for this purpose.

[0065] In an advantageous and preferred embodiment of the medical system according to the present invention, the control unit is provided and adapted to issue a visual alarm and / or prevent the start of therapy based on the detected and thus identified accessory when setting a therapy of the medical devices with a predetermined combination of the medication or medication concentration for the accessory. The provision of the illumination signal by the illumination means can be configured in different ways in order to provide such an alarm as a visual alarm signal or, if necessary, to visually support an acoustic alarm signal. For example, the alarm can be represented by a change in the illumination intensity over time, in particular by flashing or pulsing. A change in color can also be included additionally or alternatively.The invention also encompasses illumination signals that represent patterns of alternating colors. For better identification, a medical device according to the present invention may comprise a display element, e.g., on a user interface, such as a separate illuminated display, the entire display, or parts of the user interface shown on the display, configured to provide a signal that is designed in the same color as the accessory, a marker of the accessory, and / or the illumination signal.

[0066] The system can further be configured to assign different illumination signals, in particular different colors, to different functions of the system and / or the medical device. For example, an optical alarm or notification can be visualized in color, e.g. the alarm in red, the notification in orange, or with a changing flashing frequency or statically by illuminating the tubing. The illumination signal can also be a confirmation signal, e.g. to indicate that the desired disposable item with the desired medication has been inserted, or that the desired disposable item has been correctly inserted and connected. This can be visualized, for example, by a suitable signal color, e.g. green, or by a suitable other illumination signal, e.g. a constant light intensity.

[0067] The illumination signal can thus visualize the occurrence of specific system states and make them distinguishable for the user. An alarm can also be visualized using different illumination signals, and, if necessary, the different causes that triggered and detected the alarm can be differentiated. These include, but are not limited to, occlusion alarms, air alarms, pressure alarms, alarms due to an incorrectly inserted accessory, alarms due to an incorrectly but correctly inserted accessory, and functional impairments of all kinds. This can advantageously contribute to faster, ergonomic troubleshooting and error handling by the user. Furthermore, canceling and / or acknowledging an alarm can also lead to a change in the illumination signal, e.g., a change in color or intensity.

[0068] In an advantageous and preferred embodiment of the medical system according to the present invention, the control unit is provided and adapted to illuminate, in a field of view, a part of a hose line encompassed and / or connected by the accessory, based on a marker of the detected and thus identified accessory.

[0069] In particular, in one embodiment of the present invention, the color of the illumination signal can be controlled depending on information in the medication during comparison and / or after retrieving data from the medication database. In an advantageous and preferred embodiment of the medical system according to the present invention, the control unit is provided and adapted to store a colored illumination in the medication database depending on a medication selection and / or to color-illuminate part of a tubing comprised and / or connected by the accessory in a field of view depending on a medication selection and / or to emit a colored illumination associated with the disposable article to a recognized and associated disposable article.A specific, preferably unique, illumination signal can be assigned to a medication and / or therapy type, or to another type of medication category, such as the criticality of the medication and / or therapy. In particular, a colored illumination can then be emitted based on the recognition and assignment of the disposable article, so that the unique assignment is immediately apparent.
