Electric quantity detection system and method of implantable neuro-stimulation apparatus

Abstract

The invention discloses an electric quantity detection system and method of an implantable neuro-stimulation apparatus. The method comprises the following steps that: electric parameters of an implantable neuro-stimulation apparatus as well as time changing increments corresponding to the electric parameters are obtained, wherein the electric parameters contain total voltages and a total currents of a battery and the total currents of the battery contain a simulation current and a communication current; consumed power of the battery is obtained according to the electric parameters and the corresponding time changing increments; and then the consumed power is outputted. With the system and method, various emergency situations, including influences on the electric quantity of the battery by patient states and the operating states of the implantable neuro-stimulation apparatus, of the implantable neuro-stimulation apparatus during the application process are taken into consideration. Therefore, the changing situation of the battery electric quantity can be monitored precisely in real time and thus the operator can have the better user experience on the implantable neuro-stimulation apparatus.

Description

technical field [0001] The invention relates to an implanted medical system, in particular to a power detection system and method of an implanted nerve stimulation device. Background technique [0002] Implantable neurostimulation devices include implantable deep brain stimulation (DBS), implantable cortical stimulation (CNS), implantable spinal stimulation (SCS), implantable sacral nerve stimulation ( SNS), implantable vagus nerve stimulation device (VNS), etc.; with the development and progress of society, the development of the medical system is particularly important, especially the development of implantable nerve stimulation devices that are closely related to the human body. [0003] In the actual application process, patients are particularly concerned about the power of the implanted neurostimulation device, specifically: whether the implanted neurostimulation device can continue to be used, and further, the time it can continue to be used. In the prior art, the te...

AI Technical Summary

Problems solved by technology

In the prior art, the technical solution adopted is to monitor the voltage of the battery. When the voltage is lower than the normal working voltage, it means that the implanted nerve stimulation device can no longer continue to work. However, this solution fails to accurately solve the above-mentioned problems. The problem is that it is also impossible to remind consumers of the remaining power of the implanted neurostimulation device, or the time to continue to use it. At the same time, the working status of the device is judged by the voltage, and the probability of error is high, which leads to the patient's implantation in the existing technology.
