Head-mounted ultrasonic stimulation device and system

Abstract

The invention discloses a head-mounted ultrasonic stimulation device and system. The device comprises a shell sleeving the head of a user, a coupling sleeve is arranged in the shell, the space between the coupling sleeve and the shell is filled with a coupling liquid, and the coupling sleeve is in contact with the user's head when worn; the shell is equipped with a two-dimensional array transducer, a data transceiver unit, an integrated circuit and a battery; the data transceiver unit is used for receiving stimulus data from a control device, the stimulus data including data for controlling the intensity and the focus position of a sound field generated by the two-dimensional array transducer; the integrated circuit is used to convert the stimulus data into an excitation signal; the two-dimensional array transducer is used to generate a focused ultrasonic sound field under excitation of the excitation signal to stimulate the intracranial nerve cells; a power supply is used to supply power to the data transceiver unit and the integrated circuit. The device can form a focused sound field of multiple foci, the focus positions and sound field strength are adjustable, so that multi-focus precision ultrasound stimulation can be performed on the brain cell nucleus to achieve a therapeutic effect, with simple operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a head-mounted ultrasonic stimulation device and system. Background technique [0002] With the increasing number of patients with brain diseases such as depression and Parkinson's disease, the treatment of brain diseases has gradually become the focus of modern medical research. Nowadays, in addition to oral drugs, many brain treatments have been proposed to use external conditions to stimulate the cranial nucleus. The main methods of stimulation are light stimulation, electrical stimulation, magnetic stimulation and ultrasonic stimulation. Ultrasound stimulation has received more and more attention due to its safety, non-invasiveness and effectiveness. [0003] Technologies and tools for neural stimulation and circuit regulation are important driving forces for the development of neuroscience. The current goal of nervous system stimulation technology is to modulate ne...
