This enables the timely warning of possible malfunctions without the malfunction having already occurred.
- the broad database enables high accuracy of predictions and probabilities. The broad database is guaranteed by connecting a large number of orthopedic equipment to the evaluation unit via the computer network.
- the sensor data and / or evaluated sensor data are preferably stored in a database, which may be secured so that only authorized persons or facilities have access to this data.
- the data in this database provide a valuable basis for the further development of orthopedic technical facilities and improved 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 misuse of Avoid data.
- the orthopedic device is preferably used as a prosthesis or orthosis, the sensor data being recorded while the orthosis or prosthesis is being used.
- An application or app can be installed on a mobile terminal, for example the smartwatch, a mobile phone, a tablet or the like, with which a connection is established between the orthopedic technical device and the mobile terminal and above that between the orthopedic technical device and the computer network with the evaluation unit becomes. This simplifies the handling of both the orthopedic device and the data transmission.
- Direct communication between the evaluation unit and the computer network with the orthopedic device can be established by activating the app, without an orthopedic technician or another person having to be connected in order to extract data or into the orthopedic device or the mobile device transferred to. Updates can be transferred to the orthopedic device via the app and the mobile device, without having to make a constant adjustment by the orthopedic technician.
- communication can take place between different orthopedic components, different components or assemblies of an orthosis, prosthesis or exoskeleton or between the orthopedic component and a smart device that records body data such as pulse, body temperature and the like.
- the smart device can also record location data via a GPS system and / or record environmental information via a camera and link it to the sensor data so that environmental influences and environmental conditions can be included in the assessment of usage.
- a control device with a CPU or a computer is integrated in the orthopedic technology device in order to process the sensor data and to process the orthopedic technology device in accordance with a control program which can be stored in the CPU.
- This computing unit or CPU is advantageously used when the orthopedic technology is not in use Device, for example during charging a battery or during cleaning, for example at night, used to carry out auto-adaptive algorithms, install updates, document changes or transmit sensor data to the computer network and the evaluation device.
- a selective or atomic data transmission can take place in which not all data of a sensor or all sensors are always transmitted, but only those data or Fragments of data that are currently needed.
- Data preprocessing can already take place within the orthopedic technical device, for example in a prosthetic joint or orthotic joint, by means of the computer unit present therein, so that only the changes or the update service are transferred.
- the activity data can be recorded as individual events or events with qualitative properties.
- the individual events are defined, for example when two sensor sizes reach a certain limit value at the same time, so that a certain state can be inferred from this.
- a prosthesis hand the course from an open hand to a closed hand is dictated to the one in which the prosthesis thumb, prosthesis pointer and prosthesis middle finger are in contact with one another at the end of the movement, this can be classified and stored as a so-called pin grip.
- the entire data flow is then defined as a tweezer handle and correlated with an event value or an event number.
- the respective event or event can be saved together with a time stamp and a date stamp and transmitted via the transmitter.
- the data can be stored in the computer network or in the cloud either in a relational database or multidimensionally.
- the data is stored in a so-called cube, a cube structure or a so-called OLAP cube or OLAP data cube.
- Data storage in a cube structure enables online analytical processing (OLAP), which means that data can be stored in different dimensions, allowing analysis and query from different perspectives and in different levels of detail. By selecting a certain perspective or a certain level of detail, evaluations with different informative power and different computational effort are possible.
- criteria that are used to evaluate and compare the data can be combined with one another in almost any way.
- an operator portal for evaluating the data is preferred, which is particularly user-friendly and enables easy access to the data and easy linkability of the data to one another.
- various users can use the data without programming knowledge, for example research and development, service, product design, therapists and other users of the data in the computer network.
- the data stored in the database and in the computer network can provide an adjustment aid which can be used by a mobile terminal, for example during the adjustment process of an orthopedic device for adaptation. solution is transmitted to the respective user.
- the setting values are compared with typical setting values or with setting values for patients with a similar disposition and provided with recommendations so that the respective user can recognize whether he is within a setting range, in particular a typical setting range, or whether an extreme setting has been selected which is very high unusual and should therefore be checked.
- the check and the Ab can be done during the setting process. For example, all setting processes that have been carried out by a wide variety of orthopedic technicians, users or providers can be stored in the database and made accessible to all participants or users of the computer network, possibly in a prepared form.
- the large number of recorded, analyzed and stored data results in a typical setting range for a corresponding component or a corresponding parameter, which can be displayed, for example, on the mobile terminal of the person making the setting. If the actual setting range is then found, regardless of whether it lies within or outside the specified or proposed range, the settings made are stored and transmitted to the computer network or the cloud via the transmitter or the mobile terminal.
- the data stored in the computer network can also be used in the manufacture of an orthopedic device, in particular in the manufacture of an individual orthopedic device, such as a prosthesis or orthosis, which can be applied to a patient.
- You can, for example, measure a limb or a limb stump using a scanning device, for example a high-resolution optical scanning device.
- a digital model of the stump or limb is generated from the image data in a computer or in the computer network.
- the limb or limb stump data is compared with existing limb or limb stump data from other users, checked for similarities or differences, and checked to see whether and which embodiment of a prosthesis or orthosis is particularly good or less good for the respective user suitable is.
- the data from the computer network i.e.
- the digital experience data of the other orthosis or prosthesis users or those evaluated Data from a large number of existing orthoses or prostheses flow into the manufacturing process.
- certain material reinforcements or individual components or materials in various areas can be used particularly thick or thin in order to achieve an optimal configuration of the orthosis or prosthesis.
- the manufacturing data adjusted in this way are fed to a 3D printer or a similar additive manufacturing process, for example, so that the empirical values of the usage data flow directly into the manufacturing process of an individual or individualized orthosis or prosthesis.
- control in the orthopedic device is based on a state machine, there is a possibility that a comparison of data stored in the computer network will result in an evaluation of sensor data. If individual data or transitions of individual states do not occur at all for a specific user, the control can be modified in such a way that conditions that must be fulfilled in order to trigger or block certain transitions are no longer queried. Those conditions that never occur or are never queried can then be omitted, provided that they do not affect any safety-relevant conditions. This makes control faster or more precise, or uses less resources. The omission of transitions or conditions can be done automatically in the background by a software update or by a change service.
- Another monitoring function can be performed when registering and connecting the orthopedic device to the computer network by providing the data for analysis via the app and the mobile device.
- the analysis in the evaluation unit links a data pool of data from other orthopedic technical devices with the data of the specific orthopedic technical device and transmits the information to the orthopedic technician, the supplier and / or the manufacturer, so that they each have a status report of the orthopedic technical device.
- On the basis of the analysis and data evaluation of all comparable orthopedic technical facilities as well as the experience of the manufacturer it is possible to take steps to avoid errors via a transmitter to the user to be made available via the end device and the app and transferred to the orthopedic technical facility. This also makes it possible to define variable maintenance intervals for the entire orthopedic equipment or its components.
- the user can also contact the manufacturer and / or orthopaedist and / or orthopedic technician directly via the app if he thinks something is wrong with the prosthesis or orthosis or the exoskeleton. He can then immediately photos, videos, voice messages, etc. those who support and facilitate understanding of the problem.
- Both the mechanical components as well as the electronic components and the software can be adapted depending on the type of use, duration of use and intensity of use, so that unnecessary maintenance is avoided or, in the event of increased stress, the use of the orthopedic device in a state that requires maintenance would require, will be avoided.
- the orthopedic device therefore recognizes when service or maintenance is necessary and initiates this as required, so that the effort for the user, the orthopedic technician or the manufacturer is reduced.
- a rule set or a catalog of measures for exercises to be carried out can be developed or adapted to the respective user on the basis of the transmitted data.
- Previous exercises to maintain or restore physical functions can also be included.
- the assessment of the previous exercises and the changes in the settings within the orthopedic technical facility are adjusted after each training session on the basis of the results achieved.
- the assessment can be carried out either within the orthopedic technology facility, in the app or on a server, for example within the computer network.
- the training is tailored to the individual possibilities of the user and changed depending on the actual training effort and training progress.
- settings of the orthosis or prosthesis or the other orthopedic technology device can then be changed, for example, in the case of an artificial knee joint, the damping values for flexion when sitting down can be reduced if a training progress has been achieved or vice versa, the damping be increased when physical abilities have deteriorated.
- the sensors for detecting sensor data are, in particular, those sensors which are already provided and necessary for controlling the function of the orthopedic device. If the data from these sensors alone do not allow any conclusions to be drawn about states or changes or other desirable parameters, it may be necessary to define additional sensors or additional states and rule sets within the controller. In this way, the sensor data of the sensors, which are absolutely necessary for the functioning of the orthopedic equipment, are placed in a corresponding context in order to be able to extract the desired information content from the data.
- the evaluation can be based on the evaluation
- the risk assessment is adapted to the usage data in a large number of such or comparable orthopedic devices. If an assumed combination of sensor values in a certain situation in the original control is assumed to be a risk of a fall and a corresponding safety routine is activated, and in a very large number of such situations or in all situations, it turns out that there is actually no danger to the user exists, the risk assessment can be changed and, if necessary, the control can be changed automatically or after being checked by an orthopedic technician or the manufacturer of the orthopedic device. A security question can then be deleted or modified, which means that the Control simplified overall, the response behavior improved and the control effort can be reduced.
- Another aspect of the invention provides that data from different sensors are used jointly and optionally weighted in order to obtain the desired information.
- data relating to space, forces and electromyographic signals can be arranged on the orthopedic device in order to recognize certain movement patterns.
- the different sensors record different sizes and allow different conclusions to be drawn with regard to the respective situation with different accuracy. It can therefore be advantageous if several or all available sensor data are used to record a desired parameter or to record, for example, a movement pattern, in order to evaluate whether this movement situation or load situation actually occurs or not.
- the different sensor values can be assigned a different weighting factor for the different situations.
- the analysis of a force occurring with a force sensor can be assumed to be very accurate. Conclusions about occurring forces based on electromyographic sensor data are rather less precise.
- a corresponding weighting or factorization of the individual sensor values depending on the information to be obtained and the assignment in a probability of trust is therefore useful.
- all sensor values that may be relevant for the acquisition of the respective parameter can be combined with one another and assigned a common trust factor, so that the probability of precisely recognizing the parameters or the information is based on merged sensor data.
- the final decision can then be made as to whether there is a situation, whether a certain size is available or whether information can be assessed as being correct.
- an evaluation can take place in such a way that certain periods of use or types of use are linked to the detected physical condition.
- dermatological monitoring of the stump in the case of a prosthesis or the limbs in the case of an orthosis can take place.
- the condition of the skin for example moisture, salt content in sweat, fat content or the like, can be monitored by sensors in the liner.
- the sensors are connected to the transmitter and the evaluation device in the computer network.
- a restriction of use can be recommended or a medical product or medication for treatment or prophylaxis against dermatological damage or other damage can be transmitted to the user.
- Therapy recommendations can also be issued, for example for an electro-acupuncture or a treatment of phantom limb complaints or phantom perceptions or the like.
- the orthopedic device is to be set on the basis of sensor data, for example to change the setting of a prosthesis, changed parameters can be created and transmitted automatically. Basically, there is the possibility that the changed parameters are automatically transmitted and implemented; to increase safety, the adjustment can be made during video analysis or on site at an orthopedic technician or another expert while using the orthopedic technical device. If the expert or orthopedic technician is not on site, the setting must be started by the expert or the orthopedic technician during remote treatment, for example via a video telephone or telephone call. The user can release the orthopedic device for maintenance by pressing a button on the orthopedic device or on the terminal device, so that a remote update can only be carried out when the user releases it in conjunction with a release by the orthopedic technician or expert.
- the orthopedic technical device can be provided with a location module, for example a GPS module, in order to transmit the location data together with the emergency call. If the end device or the orthopedic device is equipped with a SIM card, the location of the user can be determined via the location of the SIM card and thus the location of the emergency can also be assigned. In addition to automatic detection of an emergency situation, the orthopedic technical device and / or the mobile terminal can be equipped with an emergency button that informs a suitable device, for example an emergency service, an orthopedic technician, the manufacturer or the like about the problem.
- a suitable device for example an emergency service, an orthopedic technician, the manufacturer or the like about the problem.
- the users of the orthopedic technology facility so wish, they can be grouped together and given each other with contact details so that a social group can form via the computer network, for example to exchange experiences or to plan and carry out joint activities.
- a further development of the invention provides that additional information is provided about the tracking of the route on which the user of the orthosis or prosthesis or other orthopedic technology device is moving.
- the current route or route is recorded via route detection, which can be carried out via a GPS system, and compared with stored environmental data.
- the environmental data can include, for example, the surface profile of the route or route to be covered or also the expected route to be covered, so that changes can be made in the orthopedic technical device on the basis of the stored information and the estimate of which route is taken. For example, translations can be changed, damping can be changed, actuators can be controlled differently or, if necessary, route recommendations can be given if it is foreseeable that a certain route cannot be covered or can only be covered with an increased risk.
- the orthopedic equipment can be adapted to the current and possibly expected terrain.
- the energy management can be adjusted accordingly. Is in the orthopedic device a device for converting kinetic Energy is available in electrical energy and this conversion is therefore possible, the energy management system can drive a correspondingly changed energy regime in the event of an expected conversion, for example by going downhill or moving downhill, for example evaluating the available energy reserves differently.
- a further development of the invention provides that the usage data of orthopedic technology devices are collected and locations that are frequently used by users of the orthopedic technology devices are recognized and particularly considered. By analyzing the movement patterns of the users of the orthopedic technology devices, a proposal adapted to the respective form of use can be made to the respective user. For example, a popular and interesting destination, such as a sight, could be recommended via a display device, whereby an optimized route recommendation can be given using the detected movement patterns of other orthopedic devices.
- a further development of the invention provides that, together with location data, different control situations and movement situations when using an orthopedic device are recognized.
