The present invention relates to a kind of Implanted medical system, specifically, relate to a kind of implantable medical devices and external controller wireless communications method one to one.
Background technology
Implanted medical system generally includes implantable neural electrical stimulator and (comprises brain deep brain stimulation DBS, implanted cortex stimulates CNS, implanted spinal cord stimulation trial SCS, implanted sacral nerves electricity irritation SNS, implanted vagus nerve electricity irritation VNS etc.), implantable cardiac electric stimulation (being commonly called as cardiac pacemaker), implanted drug infusion system (IDDS) etc.
Taking implantable neural electrical stimulator as example, mainly comprise the pulse generator, electrode and the external controller that implant.Wherein, pulse generator is connected with electrode by extension wire, thereby the burst transmissions that pulse generator is produced is to electrode, and the pulse signal that pulse generator produces transfers to specific neuronal target by electrode and carries out electricity irritation, thereby makes function of human body return to the state of normal operation.External controller comprises doctor's program controller, patient controller.
Wherein, doctor's program controller is that doctor is used for according to the device of the output parameter of pulse generator in patient's condition monitoring control agent, and common doctor's program controller can be used to control multiple pulse generators.Patient controller and doctor's program controller can communicate by wireless communications mode, magnetic coil or other communication modes and pulse generator.Patient controller is to be being used for according to the device of the output parameter of pulse generator in the situation gauge tap of oneself or control agent that patient is equipped with, adjusting voluntarily in the range of accommodation that patient only can arrange doctor conventionally.Wireless communications mode is the trend of Implanted medical system development at present, and doctor can use external controller by the output parameter of radio communication control or inquiry embedded nerve stimulator.
In prior art, as shown in Figure 1, the implantable medical devices in body and external controller carry out communication by radio, and communication collision problem likely occurs.Such as, normal communication path is the path P 2B of path P 1A, implantable medical devices 2 and the external controller B of implantable medical devices 1 and external controller A.Because radio is open, also will produce the path of following conflict: the path P AB of path P 12, external controller A and the external controller B of path P 2A, implantable medical devices 1 and the implantable medical devices 2 of path P 1B, implantable medical devices 2 and the external controller A of implantable medical devices 1 and external controller B, these conflict paths cause will disturb normal communication.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved in the present invention is to provide one can prevent that implantable medical devices and external controller from communication contention aware occurring in the time of radio communication, communicates by letter and realizes the wireless communications method one to one of binding for implantable medical devices with external controller.
According to technical scheme provided by the present invention, a kind of implantable medical devices and external controller wireless communications method one to one, comprises the steps:
A: random two address A1, A2, the receiver address of described external controller using address A1 as oneself of producing of external controller before radio communication;
B: the unique identifying information of implantable medical devices and address A2 are packaged as distribution address Frame by described external controller, and send this distribution address Frame by broadcast mode;
C: described implantable medical devices is received after the Frame of described distribution address, unique identifying information in the Frame of described distribution address is compared with the unique identifying information of oneself, as identical in both using as described in address A2 in the Frame of distribution address as oneself receiver address;
D: described implantable medical devices or external controller add address header in the time sending in communications data frame, described address header comprises destination address dst and source address src, and described implantable medical devices or external controller only receive the communications data frame that destination address dst is identical with the receiver address of oneself in the time receiving.
Preferably, in described step D, in the time that described external controller and implantable medical devices carry out two-way wireless communication, destination address dst in described external controller communications data frame is set to A2, source address src is set to A1, and the destination address dst in described implantable medical devices communications data frame is set to A1, source address src is set to A2.
Preferably, described external controller A only receives the Frame that destination address dst is A1 in the time of received communication Frame, and the different Frame of receiver address of refusal destination address dst and this external controller A so just can ensure that external controller A can only receive the Frame of implantable medical devices 1.Similarly, described implantable medical devices 1 only receives the Frame that destination address dst is A2 in the time of received communication Frame, and the refusal destination address dst Frame different with the receiver address of this implantable medical devices 1 so just can ensure that implantable medical devices 1 can only receive the Frame of controller A.
Preferably, the unique identifying information of described implantable medical devices is unique serial number.
Preferably, described implantable medical devices comprises embedded nerve stimulator, Implanted cardiac pacemaker, implanted sacral nerve stimulation device.
Compared with prior art advantage of the present invention is: because the present invention has all distributed receiver address separately before communication, in communications data frame, increase the address header for determining communicating pair mailing address, address header comprises destination address dst and source address src, implantable medical devices or external controller only receive the communications data frame that destination address dst is identical with the receiver address of oneself in the time receiving, realize the binding one to one of communicating pair, ensure that implantable medical devices and external controller can only receive mutually the other side's Frame, realize binding transmission, prevent communication interference.
