Problems solved by technology
However, a stimulus treatment program cannot cover all the daily life scenarios of patients
If the patient's living habits change, he usually needs to see a doctor again, and the doctor will adjust the electrical stimulation program again, so closed-loop control cannot be achieved, that is, the implantable neurostimulator cannot automatically adjust the stimulation output in real time according to the development and changes of the patient's condition

Embodiment Construction
[0026] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0027] as attached figure 1 As shown, a patient controller 20 with an acceleration sensor includes a power supply, a microprocessor module 21, a wireless communication module 22 for wireless communication with an implanted neurostimulator, and a wireless communication module 22 for measuring the vibration of the patient's limbs The acceleration sensor 23 of the value, the acceleration sensor 23 is connected with the microprocessor module 21.
[0028] The acceleration sensor is used to measure the tremor value of the patient's limbs. The microprocessor module processes the information input by the acceleration sensor and controls the output. When the tremor value of the patient's limbs measured by the acceleration sensor is not the minimum value, the patient controller and the implanted nerve stimulation The controller wirelessly communicates with the implantable neur...

The invention discloses a patient controller with an acceleration sensor. The patient controller comprises a power supply, a microprocessor module, and a wireless communication module used for performing wireless communication with an implantation type nerve stimulator, and also comprises the acceleration sensor used for measuring a quiver value of limbs of a patient. The invention also discloses an implantation type nerve stimulation system of the patient controller with the acceleration sensor and an automatic feedback regulation simulation output method. The acceleration sensor measures the quiver value of the limbs of the patient in real time, when the quiver value of the limbs of the patient is judged to be a minimum value, the implantation type nerve stimulator maintains a current stimulation scheme, and when the quiver value of the limbs of the patient is judged to be a non-minimum value, the implantation type nerve stimulator changes the stimulation scheme, till the quiver value of the limbs of the patient reaches the minimum value. Compared with the prior art, when the patient needs fine adjustment of a simulation output parameter due to various reasons, the patient does not need to frequently go to a hospital to see a doctor, thereby facilitating use of the patient and reducing financial burden.
Description
technical field [0001] The invention relates to an implanted medical system, in particular to a patient controller with an acceleration sensor, an implanted nerve stimulation system and an automatic feedback adjustment stimulation output method thereof. Background technique [0002] Implantable medical systems usually include implantable electrical nerve stimulation systems (including deep brain electrical stimulation DBS, implantable cerebral cortical stimulation CNS, implantable spinal cord electrical stimulation SCS, implantable sacral nerve electrical stimulation SNS, implantable Vagus nerve stimulation VNS, etc.), implantable cardiac electrical stimulation system (commonly known as cardiac pacemaker), implantable drug infusion system (IDDS), etc. [0003] Taking the implantable electrical nerve stimulation system as an example, it mainly includes a neural stimulator implanted in the body, electrodes, and an external controller. Among them, the nerve stimulator is conne...
