Definitions
- Cloud computing makes it possible to provide shared computer resources as a service, for example in the form of servers, data storage or applications, promptly and with little effort if required - mostly via the Internet and device-independent.
- the offer and use of these computer resources is defined and usually takes place via an application programming interface (API / programming interface) or via a website or app.
- API is typically a set of commands, functions, protocols and objects that programmers can use to create software or interact with an external system while the website or app is also called by an external system can, can provide applications for a (end) user, which he can use without further programming knowledge.
- services can be called up via a network with standard mechanisms, in particular using end devices such as smartphones, tablets, notebooks or workstations (keyword: broad network access).
- end devices such as smartphones, tablets, notebooks or workstations
- computer resources can be combined in order to be able to serve multiple users as required (keyword: resource pooling).
- Services can be provisioned and released elastically to scale up and down as needed, in some cases automatically. From the user's point of view, the available computer resources can then appear unlimited and services can be modified or changed in any way at any time. be adjusted (key word: rapid elasticity).
- Cloud computing also makes it possible to control and optimize computer resources based on measurable numbers that are collected depending on the respective performance, such as memory, bandwidth or active user accounts (keyword: measured service).
- edge computing computer applications, data and services are moved away from the central node, i.e. to the network periphery. For example, decentralized calculations are made where the data is actually generated or collected and/or required, with the aim of being able to work in a resource-saving manner and to prevent time delays caused by data transmission over a physical distance, i. H . to shorten the reaction times .
- Edge computing places lower demands on the bandwidth of the network connection used, combined with cost savings due to lower data volumes and the lower real-time requirements on the network connection.
- a so-called remote procedure call method can be implemented using software, which makes it possible to call up system-remote functions, which are then executed on the remote software system. The result of such functions can then be transferred back to the calling system.

- control device is further programmed to check the received first data and/or second data for controlling the blood treatment device for plausibility before using them for controlling the same and/or to, e.g. B. using trigger elements to check the admissibility of this data. So in the data memory or at another suitable place, on which the control device Blood treatment device access has to be defined as to what form, what format, what structure, etc. must have the second data and/or plausibility elements transmitted together with them in order to be able to recognize the validity of the transmitted second data.
- the second data must include certain trigger elements, that certain first data must always be assignable to the second data, while others may not be assignable, or not in specific combinations or sequences in which the processes represented by the first data are represented to run on the blood treatment device during a treatment, etc.
- the logic or to check the admissibility of the structure of the first and/or second data or to initiate such a check can also be provided on the blood treatment device.
- control device is programmed to actively receive new (or different or alternative) first data from the data memory and/or new (or different or alternative) second data from the central or external entity to request .

- control device is programmed in order to notify the central unit accordingly in the event of a predetermined event, which usually occurs when the actions of the blood treatment device encoded by means of the first data are completed.
- the central unit can be programmed to receive such messages, to analyze and, if necessary. to actively send new second data to the control device, which in turn continues the treatment using new first data, which it can assign to the new second data.
- a message can be sent to third parties, for example by means of another device with a display device, e.g. B. a mobile phone of the nursing staff .
- the control device records new, second data or first data that were actively transmitted by the third party. The control device can then, for its part, continue the treatment using new first or second data.
- the control device can contact the external or central unit and the blood treatment device can remain in an alarm state provided for such an alarm, i.e. a safe device state, until a response is received.
- the central unit could then respond with new second data (instruction sequence/recipe sequence), e.g. B. "Start UF program with rate xy for pressure reduction" - here, after successful pressure reduction, a further data exchange of second data with the central unit would be possible, but not necessary (e.g. "run a test sequence afterwards (record the pressure increase while the blood pump rate increases continuously)", “send the results back to the central unit" (including status information as to whether the pressure alarm is still present)).
- control device could ask the central unit for new instructions and/or transmit status information to the central unit.
- provision can be made for status information to be transmitted periodically (always).
- the central unit can respond to this with a different script than further second data, e.g. B. to continue the treatment using associated first data.
- an acoustic and/or visual alarm can be triggered, for example in order to inform a user, in particular hospital staff such as e.g. B. to alert the nurse or doctor.
- control device may also be possible for the control device to execute a stored general (non-individualized) response script instruction, the security of which is guaranteed by the system, if there is no response from the central unit after a predefined time window.
- some embodiments can provide for predetermined status information, which should be transmitted to the central unit, to be temporarily stored in the data memory and then collected transmitted when a connection is or has been restored.
- Status information can be all measured/calculated treatment and device parameters, in particular those that are suitable for clinical (e.g. treatment quality, duration, prescription, etc.), device-related (e.g. pressures, currents, voltages, etc. ) and/or insurance-relevant (e.g. patient data, nursing staff data, clinic, etc.) to generate logs.
- control device can be programmed to distinguish between relevant data of long-term interest, which is stored and should preferably be available again for further treatments, and data that is only relevant for a short time and therefore not to be stored, in particular according to predetermined criteria .
- data stored on the basis of this distinction can advantageously be used, for example in the event of a poor or unavailable data connection, to aggregate necessary data, for example for further operation of the blood treatment device.
- control device can be programmed to encrypt or decrypt the first data and/or the second data.
- control device is programmed to identify a sender of received data or to authenticate the addressee of sent data and/or to check for authenticity. This serves in particular to ensure that no corrupt or manipulated data can be used. State-of-the-art cybersecurity technology can be used for this purpose.
- the blood treatment device is designed as a dialysis device, hemodialysis device, hemofiltration device or hemodiafiltration device, in particular as a device for acute, chronic
- the present invention also encompasses a corresponding programming or configuration of a suitable device or a portion thereof.
- the first data and/or the second data are not data measured by means of sensors—in particular on the patient and/or on the control device or the blood treatment device and/or the extracorporeal blood circuit—are not patient data and/or are not medical data of the patient or do not include or do not include only such .
- the treatment data is not the first data and/or the second data or is not part of it.
- the treatment data, the first data and/or the second data - or parts thereof - are not compared to reference data, threshold values or ranges, criteria, etc. subjected to, compared with, or measured against here.
- One advantage of the present invention can be that the deployment of new scripts that have been developed in the meantime can be significantly accelerated on terminals that are already being used by the end customer. Instead of rolling out firmware updates via a service network (to a service technician, for example), this is advantageously done simply and promptly using the present invention, by z. B. new scripts are made available in the form of second data on the cloud server as the central unit. This advantageously helps to save time and money.
- a further advantage of the present invention can be that during a trial and/or test phase (clinical trial) special scripts for data acquisition can be implemented temporarily on a data memory (edge), which can then advantageously be used to evaluate the test phases. This can also help to save costs and time.
- regional adjustments can advantageously be automatically recognized by the end device, by the data storage device (edge) or by the cloud.
- the use of software (deployment) can be automatically adapted (settings) for these cases in the form of stored standard rules.
- applicable law e.g. General Data Protection Regulation, etc.
- a specific regional implementation of a privacy policy may apply depending on the location of the blood treatment device. If the device falls locally in this region, so if its location is in this region, z. B. the transmission of personal data requires prior de-identification, anonymization, encryption and/or the like.
- the technical implementation of the implementation of this requirement can then advantageously take place directly on the blood treatment device, for example without human intervention, by means of a software update.
- By means of the present invention can also advantageously, for example language displays and/or releases on new features are adapted to the language of the country of the location.
- a further advantage of the present invention can consist in the fact that additional data with regard to extended user guidance can be transmitted from the central unit to the control device of the blood treatment device. This can be particularly relevant in domestic applications. In these cases, it can be determined by the present invention, for example, that the installation site of the treatment device is outside a clinic, e.g. B. because the distance to other blood treatment devices exceeds a predetermined value.
- Another advantage of the present invention can be that the interface between the blood treatment device or the control device according to the invention and local or global network now also stricter regulations and requirements, u. a. from the field of cybersecurity, suffices. Areas/vectors of attack on the blood treatment device are advantageously kept small in order to keep the possibility of the blood treatment device being manipulated, in particular by external third parties, as low as possible.
