This utility model discloses an electrical stimulation control circuit and an anti-snoring device, relating to the field of medical device technology. The electrical stimulation control circuit includes: an electrical pulse output circuit, the output terminal of which is electrically connected to an electrode plate; and a main control circuit, which is electrically connected to the electrical pulse output circuit. The main control circuit controls the electrical pulse output circuit to output electrical pulses of a preset frequency and a preset pulse width to the electrode plate. The electrode plate is used to conduct the electrical pulses to the human jaw to stimulate the hypoglossal nerve. The preset frequency ranges from 18kHz to 22kHz, and the preset pulse width ranges from 45μs to 55μs. This utility model aims to solve the technical problem that existing anti-snoring devices often cannot effectively stimulate the hypoglossal nerve, thus affecting the user experience.

The application discloses a control method and device of a hypoglossal nerve stimulation device, equipment and a medium, the method comprises: acquiring a physiological characteristic signal for characterizing the breathing state of a detected object; based on the delay corresponding to the physiological characteristic signal, a breathing state space model of the physiological characteristic signal is constructed, so as to compensate for the delay when estimating the target respiratory phase of the detected object at the current time; based on the breathing state space model, the physiological characteristic signal is filtered by a specified filter to estimate the target respiratory phase; determine whether the target respiratory phase is within the preset stimulation window; if yes, output the stimulation signal; if not, return to the step of acquiring the physiological characteristic signal. Thus, by introducing delay compensation when constructing the breathing state space model, the accuracy of the stimulation signal output is improved. In addition, through real-time target respiratory phase estimation and preset stimulation window judgment, the breathing state of the detected object is tracked, and the accuracy of the respiratory phase synchronous control is improved.

A method of providing a sleep apnea nerve stimulation therapy to a subject may include detecting a respiratory waveform of the subject with a sensor. The sensor may be configured for coupling to the subject. The respiratory waveform may include a plurality of respiratory cycles each corresponding to at least one of a breath and an attempted breath of the subject. The method may also include identifying a breathing pattern within the respiratory waveform over a period of time. The breathing pattern may include a repeating pattern of a plurality of respiratory cycles followed by at least one respiratory cycle corresponding to a disordered breathing event. The method may also include generating a series of stimulation pulses with an implantable nerve stimulator configured for coupling to a hypoglossal nerve of the subject. The series of stimulation pulses may be coordinated with the breathing pattern.

Neural stimulator systems with an external magnetic coil to produce changing magnetic fields is applied on the neck, in conjunction with one or more tiny injectable objects that concentrates the induced electric or magnetic field to the hypoglossal nerve and protects the user by limiting and charge-balancing the output. Additional and non-invasive neural stimulator systems apply alternating current at one skin electrode and receive oppositely rectified currents at two other skin electrodes.
