Embodiment Construction
[0059] The implementation of the present invention will be described in detail below by taking an implantable neurostimulation system with fail-safe protection function as an example and referring to the accompanying drawings.
[0060] figure 1 As shown, the placement diagram of the implantable neurostimulation system with fail-safe protection function, including the implantable neurostimulation system with fail-safe protection function 1, the external patient controller 2, and the implantable A neural stimulation system 1 is implanted under the skin of a human body. Among them, the implantable neurostimulation system 1 with fail-safe protection function has both fail-safe detection and fail-safe protection functions. The external patient controller 2 interacts with the user through display screens, indicator lights, buzzers, buttons, and the like. The interaction between the implantable nerve stimulation system 1 with fail-safe protection function and the external patient c...

The implanted medical device has the characteristics of outstanding reliability, simple implementation method, high intellectualization degree, low power dissipation, strong instantaneity and the like, the safety, the effectiveness and the reliability of the implanted medical device are greatly improved, and the invention can be widely applied to various implanted medical devices.
Description
technical field [0001] The invention relates to a failure safety protection method and device for implantable medical equipment, and belongs to the technical field of implantable medical equipment. Background technique [0002] Many implantable devices in implantable medical instruments have the function of electrical stimulation, which can generate stimulating current to interfere with human physiological functions, so as to treat specific disease groups, but it is also accompanied by reliability issues and safety risks . [0003] Among them, the implantable neurostimulation system with a wide range of applications is taken as an example. [0004] There are many types of implantable neurostimulation systems, such as implanted deep brain stimulators, implanted spinal cord stimulators, implanted vagus nerve stimulators, etc., which are implanted in patients. Pulses are generated by the stimulation output module of the implantable nerve stimulation system, and high-frequency...
