Accompanying drawing 3 is an automatic alert program flow chart of the present utility model;
Wherein:
1, pulse generator; 101, first wireless communication module; 102, first power supply; 2, patient's controller; 201, second wireless communication module; 202, micro treatment module; 203, alarm module; 204, second source; 205, third communication module.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
Embodiment one:
As shown in Figure 1, a kind of implantable nerve electric stimulation with automatic warning function comprises: the pulse generator 1 that implants, described pulse generator 1 comprise first wireless communication module 101 and first power supply 102; And being positioned at external patient's controller 2, described patient's controller 2 comprises second wireless communication module 201, micro treatment module 202, alarm module 203 and the second source 204 that is used for pulse generator 1 radio communication.
Described patient's controller 2 is communicated by letter with second wireless communication module, 201 self-timings by first wireless communication module 101 with pulse generator 1 under the normal operating conditions.Because pulse generator 1 is that intravital its battery capacity of implant patient is fixed, for the saves energy pulse generator most of the time is in resting state, pulse generator 1 communicates with certain frequency time opening communication window with patient's controller 2, that is to say that pulse generator 1 and patient's controller are in resting state simultaneously and are in the state of listening to simultaneously.Certainly, because patient's controller 2 is not subjected to the limited restriction of battery capacity, also can be in the state of listening to all the time under the normal operating conditions.
Patient's controller 2 is an One-to-one communication with the pulse generator 1 that patient implants, be that the signal that pulse generator 1 sends can only be received that this unique patient's controller 2 also can only be controlled the intravital pulse generator 1 of this patient by unique patient's controller 2 of correspondence.Patient's controller 2 is placed on the place nearer apart from patient usually, is placed on the head of a bed during as rest, so wireless communication signals can be listened to reliably.
Accompanying drawing 3 shows the program flow diagram that implantable nerve electric stimulation of the present utility model is reported to the police automatically, at first pulse generator self check, judge when described pulse generator 1 and to detect the system failure or when unusual, then sending wake-up signal wakes patient's controller 2 automatically up and enters wireless communication state, pulse generator 1 is sent to patient's controller 2 with warning message by first wireless communication module 101 and second wireless communication module 201 then, 202 pairs of these warning messages of micro treatment module by described patient's controller 2 are analyzed, fault or unusual has taken place really as patient's controller 2 judgement systems, the micro treatment module 202 of then described patient's controller 2 sends the alarm signal that patient can perceive to alarm module 203, in time notifies implant patient to go to hospital to fix a breakdown and avoids contingent danger.As judge that system does not break down or unusually, then patient's controller 2 does not send alarm signal.
After patient's controller 2 received warning message, for example some serious and definite alarm signals were low excessively such as cell voltage, and the micro treatment module 202 of patient's controller 2 also can not analyzed directly warning message and send alarm command to alarm module 203.
Compared with prior art, this utility model has utilized existing wireless communication module in pulse generator and the patient's controller, need not in pulse generator, to increase again extra power consumption alarm device, only need software control can realize when pulse generator detect the system failure or unusual after automatic warning, in time notify patient to fix a breakdown or unusually, energy consumption is minimum.
The system failure of described pulse generator self check or abnormal signal are that battery is unusual, electrode is unusual, system resets, one or more the combination in the self check fault.The alarm module 203 of patient's controller 2 can be one or more the combination in speaker, buzzer, photoelectric alarm or the vibrating motor, sends sound, light or vibration signal etc. and can in time be notified patient by the automatic warning of the signal of patient's perception when the pulse generator self check is broken down or be unusual.
When described pulse generator 1 detects the system failure or when unusual, can have multiple communication mode that warning message is passed to patient's controller 2.First kind of communication mode be, first wireless communication module 101 of pulse generator 1 continues to send wake-up signal to second wireless communication modules 201 of patient's controller 2, and second wireless communication module 201 of patient's controller 2 also is in all the time and continues to listen to state.This communication mode can guarantee that pulse generator 1 passes to patient's controller 2 in the very first time with warning message, but power consumption relatively.
Second kind of communication mode is, when pulse generator 1 detects the system failure or when unusual, first wireless communication module 101 of described pulse generator 1 regularly sends wake-up signal to second wireless communication module 201 of patient's controller 2, because patient's controller 2 is not subjected to the restriction of battery capacity, second wireless communication module 201 of described patient's controller 2 is in all the time and continues to listen to state.
The third communication mode is, when described pulse generator detects the system failure or when unusual, first wireless communication module 101 of described pulse generator 1 regularly sends wake-up signal to second wireless communication module 201 of patient's controller 2, second wireless communication module 201 and first wireless communication module 101 of described patient's controller 2 are in the state of listening to synchronously and periodically, and this communication mode is more saved energy consumption with respect to above-mentioned other two kinds.
Implantable nerve electric stimulation with automatic warning function of the present utility model can be a kind of in implanted brain deep electric stimulation, implanted cortex electric stimulation, implanted spinal cord stimulation trial system, implanted sacral nerves electric stimulation or the implanted vagus nerve electric stimulation.
Embodiment two:
Identical among the pulse generator of the implantable nerve electric stimulation of present embodiment and the embodiment one, different with embodiment one is, as shown in Figure 2, described patient's controller 2 has also increased by the 3rd communication module 205 on the basis of embodiment one, the warning message that described the 3rd communication module 205 is sent the pulse generator 1 that receives is uploaded to its attending doctor's remote supervision system by cellular radio communication network or standard telephone network.The doctor can see these warning messages and in time handling by the NMS of safety.In the time of necessary, the doctor can adjust the working condition of patient device by this system, can also open the treatment prescription at this implant patient, has saved patient the come and go time and the expense of hospital.
After patient's controller 2 received the warning message that pulse generator 1 sends, described the 3rd communication module 205 can automatically be uploaded this warning message to remote supervision system, uploaded after also can being confirmed this warning message by patient, to avoid maloperation again.
This utility model also can have other various embodiments; under the situation that does not deviate from this utility model spirit and essence; those skilled in the art can make various corresponding changes and distortion according to this utility model, but these corresponding changes and distortion all should belong to the scope of claim protection of the present utility model.
