Description

[Technical field]

[0001] The present invention relates to a method for evaluating usage data of at least one orthopaedic technical device that is equipped or is equipped with sensors for detecting a property, a state, or a change in a property or state of the orthopaedic technical device or of a user of the orthopaedic technical device. [Background technology]

[0002] Orthopedic technical devices such as braces, prostheses, or even cuffs, wheelchairs, exoskeletons, etc. are applied to individuals. The orthopedic technical devices may have drives, locks, brakes, and / or dampers that are activated or deactivated by a corresponding control device. The control device may be connected to one or more sensors in order to change the behavior of the orthopedic technical device based on the sensor data.

[0003] From US Pat. No. 6,679,920 a device and a method for remote maintenance of an electronically controllable prosthesis are known. The prosthesis is formed as a prosthetic leg with a prosthesis socket, a prosthetic knee joint, a lower leg and a prosthetic foot. A hydraulic damper is arranged between the prosthesis socket and the lower leg, which adjusts its damping, for example, based on the force or acceleration. A separate maintenance device or a docking station can be connected to the control device of the prosthesis. The maintenance device collects, evaluates, processes and supplies the control and movement data of the prosthesis with a possibly updated data set to the control device of the prosthesis. The data transfer can be performed wirelessly via a data network or telephone lines.

[0004] US Patent No. 10,015,840 relates to an apparatus and method in which sensor data from a separate portable unit is collected and compared to a motion model. If the model does not match the sensor data, a correction command is transmitted. Once sufficient correction has been made, the correction is terminated.

[0005] At present, the user of the orthopedic technical device, the therapist or orthopedic technician, the payer, e.g. health insurance or aid organization, or the manufacturer of the orthopedic technical device, does not know whether the user of the orthopedic technical device uses the orthopedic technical device completely and correctly and whether the orthopedic technical device functions correctly. In the field of prosthetics, standardized questionnaires are sent out, completed by the patient and clinically verified. The disadvantage of this type of data survey method is that it focuses on the personal evaluation of the user of the prosthesis. Each patient has a different perception of whether the prosthesis fits correctly, is comfortable to wear, and meets their expectations and desires, so that there is no comparable data situation for an objective judgment. For example, in the case of short-term use with rental equipment, the user's feedback is rather unreliable. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] U.S. Patent No. 6,679,920 [Patent Document 2] U.S. Patent No. 10,015,840 Summary of the Invention

[0007] The object of the invention is to provide a method with which utilization data of an orthopaedic technical device can be detected and objectivably evaluated.

[0008] According to the invention, this problem is solved by a method having the features of the independent claims, advantageous embodiments and developments of which are disclosed in the dependent claims, the following description and the figures.

[0009] A method for evaluating utilization data of at least one orthopedic technical device equipped with a sensor for detecting characteristics, states, or changes in characteristics and states, in which the sensor is connected directly or via a storage device to a transmitter, provides for the transmitter to transmit sensor data provided by the sensor to an evaluation unit in a computer network, in which the sensor data is processed and evaluated.

[0010] The orthopedic technical device is formed as a prosthesis or orthosis, in particular for the upper or lower limbs, or as a mechatronic system, for example as an exoskeleton or similar device that is moved together with the user or patient. The sensor is preferably located in the orthopedic technical device and detects a property, a state, or a change in property and state with respect to the orthopedic technical device and / or the user of the orthopedic technical device. The sensor or sensors are directly connected to a transmitter or connected to the transmitter via a storage device in order to transmit data from the sensor to a device external to the orthopedic technical device. The data transmission can be performed by wire, by data carrier exchange such as a memory card transfer, or by a direct contact connection. Preferably, the data transmission is performed wirelessly, for example via a Bluetooth connection to a mobile terminal device, for example a mobile phone, a smart watch, a tablet, a mobile computer, or a similar data transfer device that is or can be connected to the orthopedic technical device. The orthopaedic technical device itself may likewise have a so-called SIM card and / or a mobile phone module, which allows direct data transmission from the orthopaedic technical device to the computer network. The computer network may be configured as a so-called cloud and have a distributed structure, which allows distributed access to the computer network. Furthermore, hardware and software resources are better utilized. An evaluation unit is implemented in the computer network, for example in the form of an analysis program that is coupled to a database in the computer network, where application data and user data are stored and evaluated.

[0011] The sensors detect and transmit to the evaluation unit preferably movement data, motion data and / or load of the orthopaedic technical device or sensor data relating to the user of the orthopaedic technical device. Movement and motion data are, for example, the speed of movement, duration, frequency of movement, movement pattern, repetitive movement pattern, force, moment, acceleration, orientation in space and relative orientation if several components of the orthopaedic technical device are combined with one sensor or several sensors. Similarly, data relating to the user, such as, for example, weight, height, body temperature, pulse, respiratory rate or the like, is relevant. These data are called up and transmitted at the request of, for example, the user himself, an orthopaedic technician or therapist, a doctor, a manufacturer or a dependent institution, such as, for example, a health insurance company or the like. The user can be requested to transmit via, for example, the evaluation unit, which may be equipped with a query function. Alternatively and in addition, the data is transferred in real time at all times during use. The data transfer on request can take place after reaching certain limit values, for example a time limit value, a load limit value, after reaching a certain number of repetitions, or after the occurrence of certain events, for example the detection of a peak load exceeding a predefined limit load or an accident. Furthermore, how the load has occurred is also an important check in non-continuous data transfer. The limit value can be reached by a single maximum load or by loads below several thresholds. The respective value can be reached by several days of intensive use or by regular use over a long period of time. Relevant parameters are, for example, the frequency of wearing of an orthopedic technical device, for example a leg prosthesis, the number of steps taken, what movements and / or exercises have been performed, whether the exercise goals set by the therapist for the user have been achieved, etc. To detect these data, it is also conceivable to combine them with data from a smart device, for example a smart watch or similar.

[0012] The sensor data is preferably detected and evaluated over the entire use time of an orthopedic technical device or devices, so that it is possible to detect the complete time course of the use and to evaluate the use data over the entire use time. Alternatively, the sensor data of one or more orthopedic technical devices are detected and evaluated in a time-limited manner. The duration of each data detection and evaluation, as well as the start and end and the identification of when and which orthopedic technical device is the subject of the data detection are documented and assigned to the respective data set. This makes it possible to document who, when and how the orthopedic technical device was used. In the case of an orthopedic technical device that can be worn on the patient's body, a kind of logbook can be worn in digital form, in which all data and settings of the orthopedic technical device as well as the use are stored. Similarly, data relating to the user of the orthopedic technical device can be detected, evaluated and stored. Advantageously, the data of the orthopedic technical device is personalized and assigned to the respective user, so that during and after the evaluation of the sensor data it can be stated whether the orthopedic technical device and the user are optimally synchronized with each other, or whether another orthopedic technical device would be better suited for the user, or whether the orthopedic technical device needs to be adapted or changed.

[0013] The sensor data stored in the database and evaluated in the evaluation device can be supplemented with an evaluation of the user and / or third parties of the orthopaedic technical device. The evaluation can be carried out, for example, by means of a questionnaire that is transmitted to and received by the user or other person. The questions can be asked and answered online, for example, via the respective terminal device with which the user or third party contacts and is connected to the computer network. For example, the user and / or third parties, for example orthopaedic technicians, therapists, mechanics or other people in the vicinity of the user of the orthopaedic technical device, can be asked at regular intervals what their impressions of the use and the orthopaedic technical device are. This allows subjective data to be added to the objective sensor data, whereby it is possible to relate the received data to the subjective feeling. This allows the orthopaedic technical device to be improved, in particular the manufacturer of the orthopaedic technical device, having access to and evaluation of the evaluated data, can infer the acceptance of the individual measures and features of the orthopaedic technical device. Instead of the evaluation using the questions provided, these evaluations can also be submitted freely. The evaluation unit evaluates the ratings or comments regarding the orthopaedic technical device within a text analysis and assigns the rating of each orthopaedic technical device to a specific behavior, a specific component, and / or software responsible for controlling the orthopaedic technical device.

[0014] As already mentioned, the transmission of sensor data can be carried out in real time, and also over the entire time of use. In this case, it is not necessary to transmit all data every time, but rather only expected changes or deviations in behavior can be transmitted as data. If the orthopaedic technical device or the orthopaedic technical device is provided with a storage device, the transmission can take place especially during a period when the orthopaedic technical device is not in use, for example at night, after the prosthesis or orthosis has been removed, or when no movement or use of the orthopaedic technical device is detected. Alternatively or additionally, the data transmission can take place at defined times, i.e. at regular intervals, at the request of the evaluation unit or a third party, or by active transmission by the user.

[0015] To prevent misuse of the data, the sensor data can be personalized and / or device-specific coded. Furthermore, the data can be encrypted so that only a limited set of people can access it. The data can also be anonymized so that third parties can be given access to the findings and results within the scope of medical research or for the development of orthopedic technology devices.

[0016] In particular, when multiple users of an orthopedic technical device, for example all users of an orthopedic technical device of a particular type or model, are connected to the evaluation device, it is possible to create convincing analyses and gain well-founded insights into the usage behavior as well as the nature and functionality of the orthopedic technical device. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] A development of the invention provides for the sensor data of several orthopedic technical devices of the same type or equivalent to be integrated and evaluated in an evaluation unit. The integration or clustering of sensor data and / or the assessment by the user or a third party of a specific model, model version, software version or equipment variant allows for quick and reliable recognition of improvements or problems based on a broad data base. Likewise, this allows for benchmarking of users or users within a usage cluster, which can also be used as an incentive or motivation for competitive thinking and contribute to accelerating treatment results.

[0018] A development of the invention provides for a risk analysis to be performed on the basis of the sensor data, and recommendations are issued to the user, the payer, the orthopedic technician, the therapist and / or the manufacturer of the orthopedic technical device on the basis of the results of the risk analysis. The risk analysis contains statements about possible failure probabilities, possible wear conditions, malfunctions, for example on the basis of a confluence of unexpected events that were not yet known at the time of creating the software for controlling the orthopedic technical device, which makes it possible to recall the device early, to warn the user or third parties, to take safety precautions, for example automatic updates by remote transmission of new programs and security measures, or the like, in order to protect the user or third parties from the consequences of failures or incorrect operation.

[0019] A development of the invention provides that, based on the evaluation, the user is automatically informed of usage instructions, warning messages and / or requests to improve usage behavior. For example, instructions on how the orthopedic technical device can be used better and / or how the physical condition can be improved can be provided to the user, for example by a transmitted training program, or by an explanation on how the orthopedic technical device can or should be set up, adapted or otherwise operated or used. Furthermore, warning messages regarding possible misuse, detected misuse or maintenance intervals that should or should not be observed can be informed. The notification is carried out via a computer network and a receiving device, which is arranged in a sending device or a mobile terminal device, for example a smart watch, a mobile phone, a tablet or similar receiving and playback device.

[0020] The orthopedic technical device may be equipped with or assigned to a control device which is also coupled to a receiver to which control data, access rights, sensor calibrations and / or changes and / or records relating to changes are transmitted. Furthermore, it is possible to carry out remote warnings, to detect changes on demand or automatically based on specific usage behavior, and to detect wear phenomena and compensate by carrying out sensor calibrations or changing the damper behavior.

[0021] A development of the invention provides that settings, changes in settings, calibrations, access to sensor data, and access rights are stored and retained retrievably in a computer network, in order to allow documenting and archiving of collected data from sensors and collected data from users or third parties by assessment or comment over the duration of use. This provides a kind of time machine that makes it possible to track when and possibly who made, changed or used which settings, how the orthopaedic technical device was used, what problems occurred, or which settings and adaptations were particularly advantageous or disadvantageous. This can be realized, for example, using blockchain technology. From the data history, it is possible to recognize developments or evolutions and to make predictions regarding the need for necessary maintenance intervals, repairs, control changes or updates, if applicable. In that case, a reset to the settings of the orthopaedic technical device that has proven to be correspondingly advantageous can also be performed.

[0022] One development of the method provides for a number of orthopedic technical devices to be coupled to each other via a computer network and to exchange data. The data can be changes in software, sensor calibrations, or even utilization data. The data exchange is provided via an evaluation device and / or a computer network, whereby not all data of an orthopedic technical device needs to be transmitted to other orthopedic technical devices, but only data relevant for a specific purpose. Since it is assumed that the same orthopedic technical devices have essentially the same tasks and require or can exchange the same relevant data, it is advantageous that only orthopedic technical devices of the same or the same type are coupled to each other via a computer network. However, it is also possible to couple different orthopedic technical devices with equivalent or technically similar characteristics to each other in order to exchange data and network with each other.

[0023] Data from and to the computer network is preferably transmitted via a mobile terminal device, which data may include sensor data and assessments and / or questions as well as instructions, software updates, sensor calibrations, etc. The mobile terminal device as a connection point to the computer network is connected to the orthopaedic technical device in a suitable manner, for example over short distances by wireless technology via a so-called Bluetooth connection or other types of device-to-device data transfer. In principle, connection-free and connection-based transfers from the mobile terminal device to the orthopaedic technical device and back to the mobile terminal device are possible. The wireless connection is an alternative to a cable connection between the devices, although in principle a connection via a cable is also possible and is foreseen.

[0024] A development of the invention provides for a synthesis of selected parameters detected by sensors or derivable from sensor data to be transmitted to the user, payer, or technician or therapist of the orthopedic technical device and / or manufacturer of the orthopedic technical device at a predefined time point. This reporting service makes it possible to reduce the amount of data to be transmitted and to already perform a preselection of the data to be transmitted. The selection and possibly the calculation or derivation of parameters from the sensor data can be performed in the respective orthopedic technical device, for example in order to utilize the computing capacity present in the orthopedic technical device just when the orthopedic technical device is not in use. In particular, the parameter profile, i.e. the progression of the parameters over time, can be of particular importance to a corresponding group of people or organization, since from this profile it is possible to derive inverse inferences regarding the usage behavior, the technical changes of the orthopedic technical device and the need to adapt or change the parameters or the orthopedic technical device. If only the parameter profile is detected and displayed, and in particular also transmitted, the amount of data to be transmitted is reduced as well.

[0025] A development of the invention provides for a specific data structure to be created for each user and / or each orthopaedic technical device, with which the sensor data are selected and transmitted to the evaluation unit. The data structure of the data to be imported or the assessment is individualized in order to obtain maximum persuasiveness from the sensor data and, on the other hand, to detect only the sensor data necessary for the care of the user of the orthopaedic technical device or for the optimal use of the orthopaedic technical device. If the user is not able to perform a certain movement or to use the orthopaedic technical device in a certain way, for example, the sensor values ​​that represent or allow such use to be inferred are not imported into the evaluation profile and the corresponding fields of the data structure are not filled. The same applies for the individual adaptation of the orthopaedic technical device to the respective user, for example with a change in the hardware and / or software configuration. Thus, by means of the specific data structure, only data that is relevant to or realizable by the respective orthopaedic technical device and / or user is queried.

[0026] A development of the invention provides for a selection from a plurality of alternative orthopedic technical devices using the evaluation and / or assessment of the sensor data and / or the data and / or assessment of other users, the selection being proposed to the user of the orthopedic technical device, the orthopedic technician and / or the payer. The selection can be made, for example, by the manufacturer or a central evaluation agent and / or the payer, and the proposal for an alternative orthopedic technical device or an alternative supply can be made based on the movement data, the usage data, the degree of utilization of the dynamics of the movement, the duration of the movement and the duration of the usage and / or other parameters. For example, careful handling and regular maintenance can also be proposed as aspects for providing the patient with a more valuable orthopedic technical device. If the supply of the current orthopedic technical device is not required by the user, i.e. the user does not fully utilize or is not able to fully utilize the potential of the orthopedic technical device or if it turns out that a less expensive supply is sufficient based on the change in the usage behavior, an alternative supply or an alternative orthopedic technical device can be proposed and used accordingly to the respective user. As already mentioned, in lieu of, or in addition to, alternative orthopedic technical devices, training programs, drills, or other instructions or encouragement may be transmitted to users or therapists to optimally utilize currently existing and used orthopedic technical devices and to maximize benefit to the patient.

[0027] One development of the invention provides for the evaluation unit to correlate data relating to the user of the orthopedic technical device and / or the orthopedic technical device and / or comparable orthopedic technical devices, derive probabilities for malfunctions or adverse effects therefrom, and transmit these probabilities to the user, the orthopedic technician, the payer, and / or the manufacturer. This allows for a timely warning of possible malfunctions without a malfunction occurring. A broad data base allows for highly accurate predictions and probabilities. A broad data base is ensured by connecting a number of orthopedic technical devices to the evaluation unit via a computer network.

[0028] The sensor data and / or the evaluated sensor data are preferably stored in a database, which may be protected, whereby only authorized persons or devices can access the data. The data in this database is a valuable basis for further developing the orthopaedic technical device and for improving its use by the respective patient. Access to the evaluation unit and / or the computer network can be restricted in order to comply with data protection guidelines and to avoid misuse of the data.

[0029] Preferably, the orthopaedic technical device is used as a prosthesis or a brace, and the sensor data is detected during use of the brace or prosthesis.

[0030] An application or app can be installed on a mobile terminal device, for example a smart watch, a mobile phone, a tablet or the like, which creates a connection between the orthopaedic technical device and the mobile terminal device and also between the orthopaedic technical device and a computer network with an evaluation unit. This simplifies the handling of the orthopaedic technical device and the data transfer. By starting the app, a direct communication with the orthopaedic technical device can be created between the evaluation unit and the computer network without the intervention of an orthopaedic technician or other person to extract or transfer data to the orthopaedic technical device or to the mobile terminal device. Updates can be transferred to the orthopaedic technical device via the app and the mobile terminal device without time-consuming configuration by the orthopaedic technician. Furthermore, communication can take place between different orthopaedic technical components, between different parts or assemblies of an orthosis, prosthesis or exoskeleton, or between an orthopaedic technical component and a smart device that detects body data such as pulse or temperature. Smart devices can also detect location data via a GPS system and / or record surrounding information via a camera and link with sensor data, so that environmental influences and surrounding conditions can be factored together in determining utilization.

[0031] A control device with a CPU or computer is integrated into the orthopaedic technical device to process the sensor data and to process the orthopaedic technical device according to a control program that may be stored in the CPU. This computer unit or CPU is advantageously utilized to execute auto-adaptive algorithms, install updates, document changes, or transmit sensor data to a computer network and evaluation device while the orthopaedic technical device is not in use, for example during charging of the accumulator or cleaning, for example overnight.

[0032] In order not to restrict the operation of the orthopaedic technical device by transferring data or to not overload the computer unit or the CPU, a selective or atomic data transfer can take place, in which not all data of one or all sensors are transferred all the time, but only the data or data fragments that are used at the time. Within the orthopaedic technical device, for example in a prosthetic or prosthetic joint, pre-processing of the data can already take place by the computer unit present there, whereby only changes or change services are transferred.

[0033] Similarly, data transfer can also take place, for example within the scope of activity monitoring, only when the prosthesis is actually used. Activity data can be detected as individual events or events with qualitative characteristics. An individual event or event is determined, for example, when two sensor quantities reach certain limit values ​​simultaneously, from which a certain state can be inferred. The same applies to the data profile. For example, in the case of a prosthesis, if a profile can be detected from an open hand to a closed hand in which the prosthetic thumb, prosthetic index finger and prosthetic middle finger abut against each other at the end of the movement, this can be classified and stored as a so-called pincer grip. The entire data profile is then defined as a pincer grip and associated with an event value or number of events. In that case, it is only necessary to transmit the number of pincer grips, and not all data regarding the profile of the prosthetic movement need to be transmitted, without the information content of the evaluation device or the user or other devices changing. The same applies to the ascertainment of the force profile in the prosthesis, where first the forefoot is loaded, a backward rotation of the leg is detected and then an increased load on the heel is recognized. This type of scenario may be identified as walking backwards and may be stored accordingly as a separate occurrence or event.

[0034] Each occurrence or event can be time-stamped and date-stamped, stored together, and transmitted via a transmitter.

[0035] The data can be stored in relational databases or multi-dimensionally in a computer network or in the cloud. The data is stored in the form of so-called cubes, cube structures or so-called OLAP cubes or OLAP data cubes. Storing the data in cube structures allows Online Analytical Processing (OLAP), whereby analysis and queries can be carried out from different perspectives and at different levels of detail based on the storage of the data in various dimensions. By selecting a particular perspective or a particular level of detail, evaluations can be made with different compellingness and different computational complexity. In addition to this, the criteria on which the data are evaluated and compared with each other can be combined with each other in almost any way. Despite the storage in complex cube structures, an operation portal is preferably provided for the evaluation of the data, which is particularly user-friendly, allows easy access to the data and allows easy linking of the data with each other. With a front end of this kind, the data can be used by different users without programming knowledge, making the data accessible in a computer network available to, for example, research and development, service, product design, therapists and other users.

[0036] The data stored in the database and the computer network can provide setting assistance, which is transmitted to the mobile terminal during the setting process of the orthopaedic technical device, for example, for adaptation to the respective user. The set values ​​are compared with typical set values ​​or with set values ​​of patients with a similar disposition, and recommendations are made, so that the respective user can recognize whether they are within a set range, in particular within a typical set range, or whether an extreme set has been selected that is unusual and therefore needs to be checked. Checks and adjustments can be made during the setting process. For example, all setting processes performed by different orthopaedic technicians, users or dependents can be stored in a database and made accessible to all participants or users of the computer network, possibly in a prepared form. From the acquired, analyzed and stored data, typical set ranges of the corresponding components or of the corresponding parameters are revealed, which can be displayed, for example, on the mobile terminal of the person setting them. When an actual setting area is found, regardless of whether the setting range is within or outside a predetermined or previously proposed range, the setting made is stored and transmitted to a computer network or cloud via a transmitter or mobile terminal device.

[0037] The data stored in the computer network can also be used during the manufacture of orthopedic technical devices, in particular during the manufacture of individual orthopedic technical devices, such as prostheses or orthoses that can be worn by a patient. These data can be, for example, detected by a scanning device, for example a high-resolution optical scanning device, of the limb or limb stump. A digital model of the stump or limb is generated from the image data in the computer or computer network. The limb or limb stump data is compared with already existing limb or limb stump data of other users, checked for commonalities or differences and checked as to which embodiment of the prosthesis or orthosis is particularly well or less well suited to the respective user. Data from the computer network, i.e. digital experience data of other prosthesis or prosthesis users or of the evaluated data of several already existing orthoses or prostheses, flows into the manufacturing process. In order to optimally form the orthosis or prosthesis, for example, certain material reinforcements or individual components or materials can be used that are particularly thicker or thinner in some areas. The adapted manufacturing data can then be fed, for example, to a 3D printer or similar additive manufacturing process, so that the experience of the application data flows directly into the manufacturing process of the individual or personalized prosthetic or prosthetic device.

[0038] If the control in the orthopedic technical device is based on a state machine or a state machine, the sensor data can be evaluated by comparing it with the data stored in the computer network. If the transition of the respective data or the respective state for a particular user does not occur at all, the control can be changed until the conditions that must be fulfilled to trigger or block a particular transition are no longer interrogated. Conditions that never occur or are never interrogated can be omitted, as long as these conditions do not correspond to safety-related conditions. This makes the control faster or more accurate or less resource-intensive. The omission of transitions or conditions can be performed automatically in the background by software updates or by a modification service.

[0039] From the data stored during the patient's use, together with the version history of each control or program, and the identified hardware components, and the user profile, suggestions are made on how to change the settings of the orthopedic technical device to allow for optimization and tailored control for the respective user. Similarly, training programs or other training information can be created based on the specific usage data and user profile and can be transmitted to the user, therapist or orthopedic technician, or manufacturer.

[0040] When the orthopaedic technical device is not in use or is in a charging station for cleaning or charging the accumulators, data exchange and self-analysis can take place automatically. For example, if it is detected that a part is broken, that a wear limit has been nearly reached or that a maintenance deadline is approaching, appropriate information can be issued to the user and / or a technician or therapist, so that a repair request or maintenance or even a software update can be initiated, independently of the occurrence of an error and without any action by the user. The user can be informed that an appropriate request has been made or that appropriate maintenance or repair is required.

[0041] It is also possible to issue information to the user about whether or how the orthopedic technical device has been used. In the event of misuse, instructions on other ways of use or on avoiding overloading can be transmitted, for example, to a mobile terminal device. Automatic information on the status of the orthopedic technical device can also be transmitted to the manufacturer via the cloud or a computer network.

[0042] Further monitoring functions are performed when the orthopedic technical device is registered and connected to the computer network, by providing data for analysis via the app and the mobile terminal device. The analysis in the evaluation unit links the data pool from the data of other orthopedic technical devices with the data of the specific orthopedic technical device and transmits the information to the orthopedic technician, the supporter and / or the manufacturer, so that the orthopedic technician, the supporter and / or the manufacturer each have a status report of the orthopedic technical device. Based on the analysis and data evaluation of the experience of all comparable orthopedic technical devices and manufacturers, steps can be initiated to avoid errors, made available to the user by the transmitter via the terminal device and the app, and forwarded to the orthopedic technical device. Accordingly, it is also possible to determine variable maintenance intervals for the entire orthopedic technical device and its components. Furthermore, if the user believes that something is wrong with the prosthesis or orthosis or exoskeleton, he can also directly contact the manufacturer and / or the orthopedic surgeon and / or the orthopedic technician via the app. In that case, the user can also send along photos, videos, audio communications or the like, which will aid and facilitate understanding of the issue.

[0043] The mechanical and electronic components and software can be adapted depending on the type, duration and intensity of use, thereby avoiding unnecessary maintenance or avoiding use of the orthopaedic technical device in conditions that would require maintenance if the load increases, i.e. the orthopaedic technical device knows when servicing or maintenance is required and allows servicing or maintenance to be performed as needed, thereby reducing expenses for the user, orthopaedic technician or manufacturer.

[0044] Based on the transmitted data, a rule set or a catalog of measures for exercises to be performed can be created or adapted for the respective user as an aid in the rehabilitation process or for maintaining physical capabilities. Previous exercises for maintaining or regenerating physical functions can also be taken into account. The determination of the previous exercises and the change of settings in the orthopedic technical device can be adapted based on the results achieved after each training. The determination can be made in the orthopedic technical device, in an app, or on a server, for example in a computer network. The training is accordingly adapted to the individual possibilities of the user and is changed depending on the actual training effort and training progress. In that case, the settings of the brace or prosthesis or other orthopedic technical device can be changed in conjunction with the training progress or training state, for example in an artificial knee joint, the damping value of the flexion when sitting down can be reduced if the training progress has been achieved or the physical capabilities have declined and damping has increased conversely.

[0045] The sensors for detecting the sensor data are in particular sensors that are already provided and necessary for controlling the function of the orthopedic technical device. If the data of these sensors alone do not yet allow the inverse inference of the state or the change or other desired parameters, it may be necessary to define additional sensors or additional states and rule sets in the controller, so that the sensor data of the sensors that are absolutely necessary for the function of the orthopedic technical device can be set in the corresponding context and the desired information content can be extracted from the data.

[0046] Insofar as there is a risk estimation in the control or control program stored or assigned to the orthopedic technical device, in which a certain dangerous situation is inferred upon the occurrence of a certain state or a certain combination of sensor values, an adaptation of the risk assessment can be carried out in a number of such or equivalent orthopedic technical devices on the basis of the evaluation of the usage data. If in the initial control, in the inferred combination of sensor values ​​in a certain situation, a risk of falling is inferred and a corresponding safety routine is initiated, and if a large number of such situations or even all of them turn out to be in fact no danger to the user, the risk estimation is changed and the control can possibly be changed automatically or after testing by an orthopedic technician or the manufacturer of the orthopedic technical device. In that case, the safety inquiry can be cancelled or modified, which simplifies the control as a whole, improves the response behavior and reduces the control effort.

[0047] Another aspect of the invention provides that data of different sensors are used together, and possibly weighted, to obtain the desired information. For example, data of spatial position, force and electromyographic signals can be arranged on an orthopedic technical device to recognize certain movement patterns. Different sensors capture different quantities and allow different inverse inferences with different accuracy for the respective situations. It can therefore be advantageous if multiple or all available sensor data are used to detect desired characteristic quantities or, for example, to detect movement patterns in order to evaluate whether these movement or load situations are actually occurring. Different sensor values ​​can be provided with different weighting factors for different situations.

[0048] The analysis of the force produced by the force sensor can be assumed to be correct with a very high probability. The inverse inference of the force produced based on the electromyographic sensor data is rather less accurate. Therefore, it is useful to appropriately weight or factor the individual sensor values ​​depending on the information obtained and assign them with a confidence probability. Furthermore, all sensor values ​​that may be relevant for detecting the respective characteristic quantity can be combined with each other and assigned a common confidence factor, so that the probability of correct recognition of the parameter or information is generated based on the fused sensor data. Then, based on the individual and fused sensor data with the respective associated weighting, a final decision can be made as to whether a certain situation exists, whether a certain quantity exists, or whether the information can be judged to be correct.

[0049] Sensors that are in direct contact with the patient or user of the orthopedic technical device or that can detect information about the user of the orthopedic technical device can be evaluated so that a particular duration or manner of use is associated with the detected physical properties. For example, dermatological monitoring of the stump in a prosthesis or the limb in a brace can be performed. If the prosthesis is equipped with a liner, the skin condition, such as humidity, salt content in sweat, fat content, or the like, can be monitored by sensors in the liner. The sensors are connected to a transmitter and an evaluation device in a computer network. If an overload or a dermatological overload is detected, a usage restriction can be recommended or a medical product or medicine can be transmitted for the treatment or prevention of a dermatological or other disorder in the user. Similarly, a treatment recommendation can be issued, such as electroacupuncture or treatment of phantom limb pain or phantom sensations, or the like.

[0050] Insofar as the orthopaedic technical device is to be configured based on sensor data, for example to change the settings of a prosthesis, the changed parameters can be created and transmitted automatically. In principle, the changed parameters can be transmitted and implemented automatically, and adjustments can be made during the use of the orthopaedic technical device, either within the scope of video analysis or on-site, under the supervision of an orthopaedic technician or other expert, to increase safety. In the absence of an expert or orthopaedic technician on-site, the setting by the expert or orthopaedic technician must be initiated, for example during a remote procedure by video or telephone. The user can authorize the maintenance of the orthopaedic technical device by pressing a button on the orthopaedic technical device or on the terminal device, so that remote updates can only be performed with the authorization of the user together with the authorization of the orthopaedic technician or expert.

[0051] With this method, it is possible to set up an orthopedic practice remotely, via the Internet and computer networks, where experts or therapists can support local staff on-site, who may not be experts, with video analysis, telephone consultations, and data from the system, and / or train users of orthopedic technical equipment. From the data associated with the audio information from the telephone and the visual information from the video transmission, it is possible to set up a location-independent orthopedic practice, which creates algorithms for analyzing movement profiles, providing automated suggestions for changes in software, and / or for hardware adaptation with the help of data from the computer network. The algorithms can be transmitted to the experts, who then send them to each individual patient, adapt them, and support the staff on-site.

[0052] By coupling the orthopaedic technical device to a computer network, it is possible to automatically issue an emergency call when an emergency situation, such as a fall or the like, is detected. The orthopaedic technical device can be equipped with a location measurement module, such as a GPS module, in order to transmit location data together with the emergency call. If the terminal device or the orthopaedic technical device is equipped with a SIM card, the location of the SIM card can simultaneously determine the user's location and thus the location of the emergency. In addition to the automatic recognition of an emergency situation, the orthopaedic technical device and / or the mobile terminal device can be equipped with an emergency button, which can inform the appropriate authorities, such as emergency services, orthopaedic technicians, manufacturers, or the like, about the occurrence of a problem. In addition to falls, technical problems can also be automatically reported, so that, for example, in the case of low battery capacity, a replacement battery can be ordered early and delivered or offered for replacement.

[0053] In addition to emergency situations, the properties of the orthopedic technical device can also be changed based on the data from the positioning function, e.g. changing the signal volume / feedback when leaving a building or changing the movement mode depending on the surroundings.

[0054] To the extent that users of orthopedic technical devices wish, they can be integrated and grouped together and equipped with mutual contact data, so that social groups can be formed via a computer network, for example for the purpose of exchanging information or for planning and carrying out joint activities.

[0055] In principle, in addition to the basic supply of software and information via the computer network, additional services can be provided separately, possibly at a cost, and made available individually to each user or orthopedic technician.

[0056] A development of the invention provides for additional information to be provided by tracking the route travelled by the user of the prosthesis or prosthesis or other orthopaedic technical device. By route recognition, which can be performed via a GPS system, the current course or route is detected and adjusted to the stored surrounding data. The surrounding data can for example include the surface shape of the course or route followed or expected to be followed further, so that modifications of the orthopaedic technical device can be made based on the stored information and an estimation of the route to be taken. For example, if it can be foreseen that a certain section cannot be passed or can only be passed with high risk, it is possible to change the gear, vary the damping, control the actuators differently or possibly provide a route recommendation. The orthopaedic technical device can be adapted to the current and possibly expected terrain. The energy management system can be adapted accordingly. If the orthopaedic technical device is equipped with a device for converting kinetic energy into electrical energy, whereby this conversion is possible, the energy management system can steer the energy regime which is accordingly altered if a conversion is expected, for example by walking or moving downhill, and can, for example, provide a different assessment of the available energy reservoir.

[0057] A development of the invention provides that usage data is collected by the orthopaedic technical device and that locations frequented by the user of the orthopaedic technical device are recognized and in particular observed. By analysis of the movement patterns of the user of the orthopaedic technical device, suggestions adapted to the respective usage are offered to the respective user. Thus, via the display device, arbitrary and interesting destinations, such as sights, can be recommended and optimal route recommendations can be provided using the recognized movement patterns of other orthopaedic technical devices. A development of the invention provides that, together with the position data, various control and movement situations of the use of the orthopaedic technical device are recognized. If tripping processes are frequently recognized in certain areas or in certain locations, these locations or areas can be transmitted together with the GPS data to the respective controller. A warning message is issued when the user of the orthopaedic technical device reaches or approaches a location associated with a high risk of exposure. On the other hand, locations where unexpected events or disturbances to the normal movement process are not reported can also be indicated and recommended as being particularly desirable and suitable for the respective user of the orthopaedic technical device.

[0058] A development of the invention provides for assigning map apps for different mobility grades, including a GPS module, to the orthopaedic technical device. Thus, it is possible to find a route taking into account the nature of the road, for example roads without stairs or with a flat gradient can be taken into account when selecting the route. Depending on the mobility grade, different route recommendations can be issued that are adapted to the respective user. The traveled distance can be detected and stored at the same time as a movement pattern, whereby the activity grade of the respective user is detected. Analogous to a fitness app, it can be detected whether and how the respective user of the orthopaedic technical device moves. On the basis of this, exercise recommendations can be provided. Furthermore, it is possible to adapt the predicted exercise duration or the duration of the course to the mobility grade of the respective user depending on the individual movement data. The predicted or estimated time for traveling a certain road can be adapted to the personal average speed of the respective user, and possibly various obstacles on the road can be taken into account, whereby the predicted section changes depending on the expected obstacles.

[0059] The map can be marked with road characteristics, such as, for example, stairs, obstacles, gradients, dome pavement, gravel or asphalt. Furthermore, it is possible for the user to mark it himself, for example to identify obstacles and to suggest alternative routes. A development of the invention provides that an app for public passenger local transport is set up with an assessment of the respective mobility grade present. Route planning or journey planning by public transport means can be made by grading with the mobility grade of the prosthesis or prosthesis or other selected orthopedic technical device. In this case, buses, trams, trains, stations, stops etc. can be assessed and can be reached in the same way and are available with the respective different mobility grades or other orthopedic technical devices. Relevant aspects would be, for example, flat entrances, wide entrances, grab-able handrails or the presence of elevators, escalators or the like.

[0060] A development of the invention provides for the provision of a periphery recognition, for example by a corresponding sensor system. Ultrasonic and / or radar sensors can scan the periphery and possibly existing actuators trigger a change in control before a dangerous situation occurs. In an orthosis and / or prosthesis, the ankle joint and the knee joint can be controlled together, whereby a coordinated damping behavior can be performed in case of recognition of a occurring or imminent danger. Ultrasonic sensors, radar sensors, cameras or sonar can be used. The sensors generate a periphery map, which allows the user of the orthopedic technical device to detect in which periphery he moves. It is estimated which obstacles are present in the periphery or which movement situation the user is expected to face. If, for example, stairs are recognized, a changed damping or drive behavior can be activated. From the image data or other sensor data, the nature of the ground can be recognized, whereby actuators can be activated, for example, to increase dorsiflexion. The sensors can be arranged anywhere in the orthopedic technical device, for example in the case of a prosthetic device at the respective knee joint, and in case of accommodation problems the sensors can also provide data for a foot element, for example a prosthetic foot or an orthotic foot plate, via the knee-ankle coupling.

[0061] A development of the invention provides that an orthopedic technical device, for example a brace, prosthesis or wheelchair, is individualized and design proposals are submitted via a data network, which can be evaluated and possibly selected by other users of the orthopedic technical device, in particular of comparable orthopedic technical devices. Within a certain time, a certain number of proposals and designs can be submitted or uploaded and can be voted on. Various criteria can also be given, for example a motto, on the basis of which new design proposals can be submitted. The motto can be changed according to the season or for special occasions. The networking of several users of the orthopedic technical device allows the respective users to alert each other in case of problems, so that a user of the orthopedic technical device can set up an emergency call to the cloud or data network in order to ask for help from other users of similar or comparable orthopedic technical devices, for example if the energy storage is empty or there is no charging device. The app can be displayed to users of similar orthopedic technical devices in the vicinity and can be anonymized if necessary. Similarly, it may be possible for a user of the orthopaedic technical device to be able to search for other users of the orthopaedic technical device if they so desire.

[0062] One development of the invention contemplates that a basic model of data and data services is provided first, and additional services or features can be acquired or released, for example as a response to released data or user profile.

[0063] By recovering energy through movement, for example walking or running downhill, current is stored in the energy reservoir, thereby making it possible to extend the battery life.

[0064] New wireless technologies, such as LTE or 5G, can be incorporated to improve the quality of service. A system can be incorporated into the orthopedic technology device that sends data directly to a server to facilitate later evaluation and automatic learning.

[0065] The configuration of the orthopedic technical device can be performed with the aid of augmented reality, for example with virtual reality glasses, hollow lenses, augmented reality glasses, or the like. The required data can be directly faded in, the respective surroundings can be detected, as well as surveying and object recognition can be performed via detection devices, such as glasses or the like, whereby evaluation and measurement can be performed with a direct evaluation of the data by the camera of the glasses. The prosthetic hand can be equipped with authentication elements, such as mass storage devices, RFID, chip cards, Bluetooth connectors, or the like, in order to enable automatic authentication at interfaces such as bank ATMs, hospitals, Internet or other access controls, simply by touching or approaching the prosthetic hand. The same is done by integrating corresponding authentication devices into other orthopedic technical devices, such as prosthetic knees, prosthetic feet, prosthetic arms, or other orthopedic technical aids. Corresponding payment functions can also be integrated.

[0066] Sports and rehabilitation exercises can be detected. Similar to orthopedic technical devices, sports mats or sports equipment can be equipped with sensors, which detect movement. Sensor data are combined and evaluated to detect who performs which exercises and how. Improvement suggestions, alternative exercises, exercise recommendations, and detection of improvement or possibly deterioration of the condition can be made.

[0067] The orthopedic technology device can be used as an IOT hub-enabled platform for additional systems or software, allowing the prosthetic, orthotic, or other orthopedic technology device to be easily expanded, in some cases incorporating new functionality that has nothing to do with the orthopedic technology device itself.

[0068] Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. [Brief description of the drawings]

[0069] [Figure 1] 1 is a schematic diagram of an orthopedic technical device. [Diagram 2] FIG. 1 shows a variant of the invention with a brace. [Diagram 3] FIG. 1 shows a variant of the invention in a storage system. EXAMPLES

[0070] 1 shows a schematic diagram of an orthopedic technical device 100 in the form of a leg prosthesis with a prosthetic knee joint having an upper part 1 to which is attached a thigh socket 10 for receiving the patient's thigh stump. A lower part 2 in the form of a lower leg is supported in the upper part 1 so as to be pivotable about a pivot axis 4. The lower part 2 has a lower leg pipe 5, to the distal end of which is attached a prosthetic foot 3, which can be pivotably supported on the lower leg pipe 5.

[0071] The orthopaedic technical device 100 is arranged with a number of sensors 9 for collecting sensor data relating to the use or state of the orthopaedic technical device 100. In the illustrated embodiment, the ankle moment M A A sensor 9, for example, is arranged on the foot 3 to detect the effective axial force F A Sensors 9 are arranged on the lower leg pipe 5 to detect the position of the lower part 2 in space, and for example angle sensors 9 are attached to the lower part 2, possibly in combination with inertial angle sensors, to detect the spatial position of the lower part 2 during use of the orthopedic technical device 100. Inertial sensors 9, moment sensors, angle sensors, temperature sensors and other sensors can be arranged or incorporated in the thigh socket 10.

[0072] Furthermore, a resistance device 6 in the form of a damper or actuator is arranged in the lower part 2, which is supported between the upper part 1 and the lower part 2 in order to provide a settable extension and flexion resistance, especially when the resistance device 6 is formed as a passive damper. An adjustment device 7, for example a motor or other drive, a magnet or the like, is assigned to the resistance device 6, which can vary the respective resistance in the resistance device 6. If the resistance device 6 is formed as a hydraulic or pneumatic damper, the adjustment device 7 can enlarge or reduce the respective flow cross-section of the overflow channel between the extension chamber and the flexion chamber, or vary the flow resistance in another way. Similarly, the adjustment device 7 can vary the viscosity of the fluid contained in the resistance device 6, for example by changing a magnetic field and by acting on the magnetorheological fluid. If the resistance device 6 is formed as an electric motor, the electric motor can be operated in generator mode, thereby varying the mechanical resistance to flexion or extension of the upper part 1 relative to the lower part 2. Insofar as the resistance device 6 is configured as a motor and is operated in motor mode, active assistance of the flexion and / or extension of the prosthetic device is possible.

[0073] The adjusting device 7 is coupled to the control device 8 so that it can be activated or deactivated in order to influence flexion and / or extension and, if necessary, to block the joint. The desired behavior of the orthopaedic technical device 100 is set by the control device 8 via a corresponding activation or deactivation signal to the adjusting device 7. The adjusting device 7 is activated or deactivated by the control device 8 on the basis of sensor data transmitted from the sensor 9 to the control device 8. The sensor data from the sensor 9 can be preprocessed or processed in the control device 8 itself, for example to calculate the angular velocity or acceleration from the angle data. Insofar as the desired data is directly detected by a sensor, for example an angle sensor, an acceleration sensor or the like, a corresponding preparatory process can be omitted. The control device 8 is equipped with or coupled to a computer or processor for electrically or electronically evaluating the data and for correspondingly activating or deactivating the adjusting device 7 on the basis of this evaluation.

[0074] The sensors 9 are connected to the control device wirelessly or by cables or other conductive line devices. Insofar as wireless communication takes place between the sensors 9 and the control device 8, corresponding transmitting and receiving devices are provided in or assigned to the control device 8 and the sensors 9.

[0075] The control device 8 may also have a memory device 12 or may be coupled to a memory device 12 that records the sensor data and the sensor data profile, or an evaluation of the sensor data and the sensor data profile, for further use or transmission at a later point in time.

[0076] A transmitter 11 and a receiver 13 are also assigned to the control device 8 for transferring sensor data, programs, access rights, settings, setting changes, software updates etc. from external devices to the orthopaedic technical device.

[0077] During the use of the orthopaedic technical device 100, data detection is performed by the sensor 9, during which all relevant data such as forces, moments, accelerations, orientation, temperature, deformations, movement time, use time, etc. are detected and transmitted to the control device 8 and possibly stored. By means of the control device 8 and the storage device 12, the sensor data and the like are transmitted directly to the evaluation device 20 in the computer network 200 via the transmitter 11, if the transmitter 11 is arranged to communicate directly with the computer network 200 or the evaluation unit 20. For this purpose, the orthopaedic technical device 100 can be provided with a SIM card for establishing a communication connection or other communication interface for creating a connection to a transmission network or the like. Alternatively or additionally, the transmitter 11 can transmit data via a mobile terminal device 30, for example a smart watch, tablet, mobile phone or laptop, from where the data is transmitted to the computer network 200. In the computer network 200, an evaluation unit 20 is arranged or formed in a centralized or decentralized manner and, if necessary, is coupled to a database 25 for storing sensor data or an evaluation of the sensor data and other data related to the use of the orthopedic technical device 100.

[0078] Based on the sensor data and other data, an evaluation and possibly a risk analysis together with recommendations, software updates, etc. is carried out in the evaluation unit 20 or in the computer network 200 .

[0079] Questions regarding the subjective assessment of the behavior of the orthopaedic technical device 100 can also be stored in the mobile terminal device 30 or can be adapted to the usage behavior and transmitted by the computer network 200 in order to obtain feedback of the respective user without the intervention of an orthopaedic technician. The orthopaedic technical device 100 and the mobile terminal device 30 can be equipped with devices for determining the location, for example a GPS module or other current location determination devices which perform corresponding location measurements, for example via a transmitting cell of a mobile radio system. On the basis of the location data, a better evaluation of the status data or the changes detected by the sensor 9 can be made.

[0080] In FIG. 2, an alternative orthopedic technical device 100 in the form of a knee-ankle brace is shown, which comprises an upper part 1 with an adjustable thigh rail, a lower part 2 with a settable calf rail, and a foot part 3 which is supported so as to be articulated and pivotable about an ankle joint axis 23. The upper part 1 is connected to the lower part 2 so as to be pivotable about a joint axis 4. Sensors 9 are shown on the upper part 1 and on the lower part 2, which can be formed similarly to the orthopedic technical device 100 according to FIG. 1. A control device 8 is arranged in the region of the knee joint axis 4, although other positions are likewise possible. All devices of the orthopedic technical device 100 according to FIG. 1 are shown and are or can be arranged there accordingly in the orthopedic technical device 100 according to FIG. 2. A transmission of sensor data to a computer network 200 via a transmitter 11, again not shown, takes place for evaluation in an evaluation unit 20.

[0081] In FIG. 3, a variant of the invention is shown, which is illustrated without the orthopaedic technical device 100 being attached. The thigh socket 10 has been removed from the upper part 1, and only some of the individual components of FIG. 1 are shown. In addition to the components according to FIG. 1, a supply terminal 16 is arranged in the lower part 2 of the orthopaedic technical device 100, which supply terminal is formed as a wireless supply terminal 16 for wirelessly transmitting energy when the orthopaedic technical device 100 is in a resting state. The supply terminal 16 comprises, for example, a coil, which is excited and transmits inductive energy via a corresponding supply device 60, which may be installed on the outer wall of a holder 50 for storing the orthopaedic technical component 100 in the detached state. The orthopaedic technical device 100 can thus be stored in the holder 50 for maintenance purposes in order to ensure the electrical supply. A cleaning assembly 70 can be arranged in the holder 50 in order to be able to carry out sterilization or similar cleaning. Similarly, an identification device 65 can be arranged in the holder 50, via which a code, for example an optical code or an electromagnetic code, can be read in order to identify the orthopaedic technical device. In addition to this, a transfer module 30' is arranged in the holder 50, which comprises a transmitter and a receiver. The transfer module 30' can receive data from the transmitter 11 of the orthopaedic technical device 100 and transmit it to the receiver 13. At the same time, the transfer module 30' can receive data from an evaluation unit 20 (not shown) of a computer network 200 equipped with a transmitter and a receiver or transmit data to such a computer network 200. Thus, only a small transmission power of the transmitter 11 to the transfer module 30' is required, which can save energy. The data transfer is preferably carried out when the orthopaedic technical device 100 is in a detached state, for example at night, when no computer power is required to process the sensor signals for controlling extension and flexion or other functions. In addition to this, when placed in the holder 50 and in a detached state with energy supply, the duration of use of the orthopaedic technical device 100 can be increased, since less energy is used for evaluation and data transfer.
