Nerve stimulation device, nerve stimulation system, electronic equipment, and storage medium

Abstract

The invention relates to the field of medical instruments, and discloses a nerve stimulation device, a nerve stimulation system, electronic equipment and a storage medium. The nerve stimulation device comprises a control module, a pulse issuing module and a sensing module, wherein the pulse issuing module is used for issuing pulses according to instructions; the sensing module is used for starting sensing of an evoked composite action potential according to the instruction; the control module is used for instructing to start the sensing module while instructing to issue the pulse; after the stimulation pulse is issued through the instruction, after sensing delay time, the control module is used for instructing to sense the evoked composite action potential; and the instruction sensing module is closed after the ECAP window time after the evoked composite action potential is sensed through the instruction, wherein the sensing delay time is the maximum value between the total pulse duration and the module conversion time. The sensing module is selectively started to sense the evoked composite action potential, so that the power consumption of the sensing module is reduced, and a good foundation is laid for reducing the size of the nerve stimulation device and prolonging the charging interval of the device.

Description

technical field [0001] The embodiments of the present application relate to the field of medical devices, and in particular to a nerve stimulation device, a nerve stimulation system, electronic equipment, and a storage medium. Background technique [0002] With the progress and development of science and technology, the technology of controlling and treating diseases by sending nerve stimulation has gradually matured. The so-called closed-loop function in neurostimulation measures how the neurostimulated organ responds to the stimulus, and then adjusts the pulses to achieve better therapeutic effects. Evoked compound action potential (ECAP for short) is the external manifestation of the fiber population's response to electrical stimulation. Clinical studies have demonstrated new scientific evidence supporting a closed-loop spinal cord stimulation (SCS) system for the treatment of chronic pain based on feedback control of ECAP. ECAP sensing can be performed during spinal co...

AI Technical Summary

Problems solved by technology

[0003] Existing neurostimulation devices generally have multiple stimulation electrodes (more than 8-16 contacts), and the power consumption of neurostimulation devices is already relatively high

In order to achieve pulse adjustment based on the ECAP sensing results, it is necessary to add an ECAP sensing function module to the nerve stimulation device. The newly added ECAP sensing function module will further increase the power consumption of the entire device.

Reducing power consumption is necessary to reduce the size of the IPG (implanted neurostimulation device) and extend the battery charging interval of the device, and the additional high power consumption brought by the newly added ECAP sensing function module will reduce the size of the IPG and increasing the charging interval of the device brings huge troubles
