    专利说明:

    The invention relates to a node device for providing data and / or energy transmission between implants arranged in the human or animal body and an extracorporeal communication unit and a method for exchanging information and / or energy between several implants arranged in a human or animal body and an extracorporeal communication unit.
    Devices located in mutual proximity are increasingly using electromagnetic, magnetic or electric fields for wireless communication and also for energy transmission. If different methods, protocols, etc. are used for this, in particular at the same time, as can easily happen when using devices from different manufacturers, it is possible that mutual interference may occur which disrupts or even makes it impossible for data communication or energy transmission. In particular in the case of implants in human or animal bodies, the problem mentioned can occur more frequently, since more and more implants are used which make use of wireless data communication or energy transmission (or both). Such devices can be, for example, cardiac pacemakers, insulin pumps, pain reliever pumps, sensors of any kind, recording devices, etc. If such devices interfere with each other in their data communication or energy transmission, this can have dangerous consequences for the health of a patient.
    It is an object of the invention to provide improved communication or energy transmission between implants arranged in the human or animal body and a communication unit arranged outside the human body.
    [0004] This object is achieved by implementing at least some of the characterizing features of the independent claim. Features which develop the invention in an alternative or advantageous manner can be found in the dependent claims.
    The invention relates to a node device having an interface for a communication and / or energy transmission process between the node device and a plurality of implants arranged in a human or animal body, the node device being configured to provide data and / or energy transmission between the Implants and an extracorporeal communication unit by means of communication or energy transmission signals. For example, the data and / or energy transfer takes place for the purpose of exchanging information or for the purpose of charging (or discharging) an energy store of the implants.
    [0006] The interface can be designed, for example, as a purely wired or purely wireless interface, or as a combined interface with wired and wireless functionality.
    The implants can be implants of the same type (from the same or different manufacturers) or implants for the same purpose, or the implants can be implants which are aimed at a different purpose or differ in type or manufacturer.
    [0008] For example, the inventive node device provides a remedy against interference signals which could disrupt or falsify the data or energy transmission between the implants and the extracorporeal communication unit, or the individual functionality of the implants themselves. Thanks to the inventive node device, the implants can, for example, be better shielded from interference signals, while at the same time, due to the clearly defined connection to the node component, the variability of the communication and energy transmission options available in the prior art is retained.
    For example, the node device is configured in one embodiment in such a way that the provision of the data or energy transmission is based on an optimization functionality which influences the information transmitted by the communication or energy transmission signals by electromagnetic, magnetic and / or electrical Fields minimized.
    The optimization functionality can be configured, for example, to coordinate the data or energy transmission between the implants and the extracorporeal communication unit in terms of time, amount and / or the signal modulations used in such a way that interference from the data or energy transmission between the extracorporeal communication unit and the implants generated electromagnetic, magnetic and / or electrical fields are minimized.
    In particular, the node device can be configured to temporally separate the data transmission and the energy transmission or for the simultaneous provision of the data and energy transmission.
    In a further embodiment, the node device has a coordination circuit which is configured to provide respective exchange protocols for transmitting the communication or energy transmission signals between the extracorporeal communication unit and different implants in each case.
    In particular, the node device has different transmission protocols for data transmission between the implants and the extracorporeal communication unit and can therefore be used, for example, as a bridge for communication between different external devices with different implants.
    In a further embodiment, the node device is configured to generate a synchronization signal and to control the implants via the interface to synchronize the exchange of communication or energy transmission signals between the extracorporeal communication unit and different implants based on the synchronization signal.
    Furthermore, the node device can also be configured to provide a clock reference for the relative and / or mutual synchronization of individual implant controls, for example to regularly ensure a defined state of individual implants and / or a relative functional relationship between different implants.
    In a further embodiment, the node device is configured to control the implants via the interface and to set a time-fixed scheme for the exchange of communication or energy transmission signals assigned to different implants.
    Furthermore, according to a further embodiment, the node device is configured as an intermediate component for data and / or energy transmission between at least one of the implants and the extracorporeal communication unit, the node device exchanging information with the at least one implant via the interface. The information correlates with the communication or energy transmission signals exchanged with the extracorporeal communication unit.
    For example, the node device can be designed as a pure relay station, i. incoming and outgoing signals are identical, or it can be configured to generate a related different forwarding signal based on an incoming signal.
    In a further embodiment the node device comprises a management circuit, e.g. based on an arbiter, wherein the management circuit is configured to detect an incoming communication signal assigned to one of the implants, to recognize the assignment of the detected communication signal (to the implant), and to forward the information carried by the detected communication signal to the implant corresponding to the assignment.
    In a further embodiment, the node device is configured to sense an incoming energy transfer signal associated with one of the implants, to recognize the association of the sensed energy transfer signal, and to provide an energy exchange, e.g. for the purpose of loading the implant, between the implant corresponding to the assignment and the extracorporeal communication unit via the interface.
    As an alternative or in addition, the node device can also have, for example, an energy source which can be used, for example, to exchange energy with at least one of the implants. In that case, the node device is configured to detect a control signal assigned to one of the implants to initiate a charge or discharge of the implant, to recognize the assignment of the detected control signal (to the at least one implant), and to use the energy source to charge or discharge the the assignment of the corresponding implant via the interface.
    For example, the knot device can be formed as part of an internal component to be arranged in the human or animal body, e.g. as a separate component or as part of an implant. Alternatively, the knot device can be designed as part of an outer component to be arranged (completely) outside the human or animal body. Furthermore, the knot device can be designed such that it has a first part and a second part, the first part being specifically intended to be arranged in the human or animal body, and the second part being specifically intended to be outside the human or animal body to be arranged.
    The invention also relates to a method for exchanging information and / or energy between several implants arranged in a human or animal body and an extracorporeal communication unit, with data and / or energy transmission between the implants and the extracorporeal communication unit by means of or mediating of a central node takes place on the basis of communication or energy transmission signals for exchanging information or charging the implants and an implant-specific signal connection to the node is provided for each of the implants.
    The node acts here as a kind of hub (eng.), By means of which communication at least with the respective implants but also with an external unit (e.g. extracorporeal communication unit) can take place. The communication on the part of the node can relate to the reception of data or information from the implants and / or the transmission of data, commands, information, etc. to the implants. Communication in the broader sense also includes the transfer of energy. Communication can be wired, contact or contactless.
    Through a central management of the communication of several communicating components made possible by the node, the communication characteristics can be chosen so that a (mutual) influence of different signals and thus an undesired influence (e.g. control) of an implant can be avoided. A clear implant-related signal assignment is possible.
    The node device according to the invention is described in more detail in the following purely by way of example with reference to exemplary embodiments shown schematically in the drawings. The same elements are identified by the same reference symbols in the figures. The embodiments described are generally not shown true to scale and they are also not to be understood as a restriction. Show in detail<tb> Fig. 1: <SEP> schematically an embodiment of the node device, the node device being arranged in the human or animal body;<tb> Fig. 2: <SEP> schematically a further embodiment of the node device, the node device being arranged extracorporeally;<tb> Fig. 3: <SEP> schematically a further embodiment of the node device with an intracorporeal and an extracorporeal part.
    Figure 1 shows schematically an embodiment of the node device 1, wherein the node device is arranged in the human or animal body 2 (intercorporeal arrangement) and a coordination of the data and / or energy transmission between the human or animal body arranged implants 3 with an outside the (extracorporeal) unit 4 arranged in the human or animal body.
    Said coordination can be carried out by the node device 1, also known as the node, in such a way that it a) coordinates the wireless data communication or energy transmission or b) takes over.
    The invention is to be understood such that all combinations are covered, such as, for example, execution of data communication or energy transmission separately, data communication and energy transmission, however, separately, data communication and energy transmission simultaneously.
    Variant a) can take place, for example, by arbitration, in which the node 1 coordinates the extracorporeal communication or energy transfer, for example, so that the various implants 3 are assigned their communication or charging times from the node 1 so that mutual interference is minimized ; Variant b) can be implemented, for example, in such a way that the node 1 redirects the communication or energy transmission of the intracorporeal devices 3 to the outside world in such a way that data or energy transmission occurs intracorporeally between one or more implants 3 and the node 1, while the node the extracorporeal data or energy transmission with one or more extracorporeal devices 5 takes over. In this case, the communication or energy transmission of the node, in particular to the outside, can also be protected in such a way that any misuse is made more difficult.
    It can be useful to implant the node 1 at a point that is easily accessible from an operational point of view, so that it can be exchanged without any problems, while the individual implants 3 can be used in less easily accessible places
    The node 1 does not have to be designed independently, but can be located, for example, in one of the implants 3, as can be advantageous in the case of a relatively large implant such as a pacemaker or an insulin pump.
    Another interesting form can be that the node 1 increases the range of a small implant, for example, by allowing a short intracorporeal route and converting this into a longer extracorporeal route.
    The node can also contain a central energy source which can supply one or more implants with energy. This can be useful if the primary implant should not contain an energy source, for example for reasons of risk, service life or other reasons, and the node therefore assumes this function of the energy source.
    It is also conceivable that an implant communicates with the node in a wired manner or carries out an energy exchange, while the node takes over the wireless communication or energy transmission to the outside. In particular, the node can contain the transmission protocols of all devices (intra- and extracorporeal) and the devices can be constructed in such a way that they can carry out communication or energy transmission with the node. Standardizing the relevant protocols can be an advantage.
    FIG. 2 shows a further possible embodiment of the node, which is designed here for an extracorporeal arrangement, so that, for example, at night the node 1 can carry out communication or energy transmission from the outside.
    Figure 3 shows a further possible embodiment of the node 1, which is designed here in split form and has a part intracorporeal and a part extracorporeal.
    It goes without saying that these illustrated figures only represent possible exemplary embodiments schematically. The various approaches can also be combined with one another as well as with prior art methods.
