Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation equipment, and particularly to a wearable music diaphragm pacemaker and its usage method. Background Art

[0002] An external diaphragm pacemaker is a portable medical device commonly used to treat patients with respiratory failure. This device can transmit electrical signals to the patient's diaphragm through electrodes, stimulating the diaphragm to contract and enabling the patient to breathe. The diaphragm is one of the most important muscles in the human breathing process. When the diaphragm cannot contract normally, patients will experience symptoms such as dyspnea. The external diaphragm pacemaker is designed to help these patients by artificially stimulating the diaphragm to contract, enabling the patients to breathe effectively.

[0003] The combined use of a diaphragm pacemaker and respiratory training is a comprehensive rehabilitation strategy. By electrically stimulating the passive activation of the diaphragm contraction and combining it with active respiratory training to enhance the function of the respiratory muscles, it has shown a synergistic effect in various respiratory dysfunction diseases.

[0004] In the prior art, the diaphragm pacemaker mainly drives breathing by presetting electrical stimulation parameters, but lacks real-time feedback regulation of the patient's spontaneous breathing rhythm and does not combine multi-sensory stimulation to enhance neuroplasticity. In addition, respiratory training often relies on the patient's subjective awareness to adjust the rhythm, and the effect is limited. Research shows that auditory cues can guide breathing by synchronizing rhythms, and mindfulness meditation music, due to its soothing properties, can reduce anxiety and enhance attention, promoting neural remodeling. To further improve the rehabilitation effect, reduce anxiety and enhance attention, a wearable music diaphragm pacemaker and its usage method are proposed. By combining mindfulness music with the diaphragm pacemaker, real-time monitoring of respiratory signals is carried out to synchronously generate electrical stimulation and auditory cues of mindfulness music, guiding the patient to adjust the breathing rhythm and promoting neural function remodeling. Summary of the Invention

[0005] The present invention provides a wearable music diaphragm pacemaker and its usage method, which solves the problems raised in the above-mentioned background art. By combining mindfulness music with the diaphragm pacemaker, real-time monitoring of respiratory signals is carried out to synchronously generate electrical stimulation and auditory cues of mindfulness music, guiding the patient to adjust the breathing rhythm and promoting neural function remodeling.

[0006] The solution of the present invention to the above technical problems is as follows: A wearable music diaphragm pacemaker includes a diaphragm pacemaker main unit, an electrical stimulation module, a respiratory monitoring module, and a wearable package. The diaphragm pacemaker main unit is connected to the electrical stimulation module and the respiratory monitoring module through wires. The electrical stimulation module uses electrode patches to apply adjustable electrical pulses to the phrenic nerve or the diaphragm. The respiratory monitoring module is provided with a piezoelectric pressure sensor to collect thoracic and abdominal respiratory movement signals in real time;

[0007] The diaphragm pacemaker host includes an auditory cue module, a central processing unit, a low-pass filter, operation buttons, and a display screen. The auditory cue module has a built-in mindfulness meditation music library. The central processing unit analyzes the respiratory signal and dynamically adjusts the electrical stimulation parameters and music rhythm.

[0008] The wearable package includes a host package, a device package, and nylon straps. The device package is provided with a zipper. The host package and the device package are fixedly connected. There are two sets of nylon straps, and both sets of nylon straps are fixedly connected to the host package.

[0009] The usage method includes the following steps:

[0010] S1: Equipment preparation and respiratory monitoring: The diaphragm pacemaker host can be placed in the host package. The electrical stimulation module and the respiratory monitoring module can be taken out of the device package. The host package can be worn on the arm through the nylon straps. The electrical stimulation module and the respiratory monitoring module are attached to the training position through medical silicone patches. After wearing, the respiratory monitoring module collects respiratory parameters.

[0011] The real-time respiratory parameters include inspiratory time (T_insp), expiratory time (T_exp), and tidal volume.

[0012] Perform deviation calculation on the parameters, define the target respiratory rhythm (T_target_insp, T_target_exp), and calculate the time deviation:

[0013] ΔT_insp = T_insp - T_target_insp

[0014] ΔT_exp = T_exp - T_target_exp

[0015] Amplitude deviation: ΔA = (A_actual - A_target) / A_target;

[0016] Use a sliding window of 5 respiratory cycles to calculate the average deviation to avoid interference from instantaneous fluctuations.

[0017] S2: Diaphragm pacing: The central processing unit of the diaphragm pacemaker host generates a target respiratory rhythm (such as 4 seconds of inspiration - 6 seconds of expiration), and synchronously starts electrical stimulation and mindfulness music accordingly.

[0018] S3: Dynamic generation of mindfulness music rhythm and pitch: The music rhythm changes dynamically with the electrical stimulation intensity. The pitch increases during inspiration and decreases during expiration.

[0019] The music beat period (BPM) is synchronized with the target respiratory cycle:

[0020] BPM = 60 / (T_target_insp + T_target_exp);

[0021] Real-time adjustment: If ΔT_insp > 0, gradually decrease BPM to extend the inspiratory phase music passage;

[0022] Use dynamic audio synthesis technology (such as Granular Synthesis) to adjust the duration and pitch of music segments in real time

[0023] S4: Dynamically adjust the electrical stimulation parameters; Monitor the patient's respiratory deviation in real time, and guide the patient to match the target rhythm by adjusting the music rhythm and electrical stimulation parameters;

[0024] Adjustment logic:

[0025] Inspiratory phase: Stimulation frequency (f_insp): Inversely proportional to the target inspiratory time (example: T_target_insp = 4s → f_insp = 0.25Hz);

[0026] Pulse width (PW_insp): Negatively correlated with ΔT_insp (ΔT_insp↑ → PW_insp↓ to extend the inspiratory time);

[0027] Expiratory phase:

[0028] Stimulation amplitude (A_exp): Positively correlated with ΔT_exp (ΔT_exp↑ → A_exp↑ to accelerate exhalation);

[0029] S5: Data storage and feedback optimization: Store the training data and generate a visual report for efficacy evaluation.

[0030] Based on the above technical solutions, the present invention can also be improved as follows.

[0031] Further, the display screen shows the electrical stimulation intensity, set time, pacing times, pulse frequency of the electrical stimulation module, and the music name and scale intensity of the auditory cue module.

[0032] Further, the diaphragm pacemaker host is installed in the host bag, the electrical stimulation module, the respiratory monitoring module and their connection lines can be received in the equipment bag, an opening is provided at the top of the host bag corresponding to the diaphragm pacemaker host, and an operation opening is provided on the host bag corresponding to the operation buttons and the display screen.

[0033] Further, in step S1, a low-pass filter is used to remove the high-frequency noise of electromyogram interference from the collected respiratory parameters. The cut-off frequency is 0.5 - 5 Hz. The moving average method or median filtering is used to eliminate baseline drift. The starting point (trough) of the inspiratory phase and the ending point (peak) of the expiratory phase are identified through the peak detection algorithm, and the current respiratory cycle length (T_cycle) and the inspiratory / expiratory time ratio (I:E) are dynamically calculated.

[0034] Further, in step S3, the real-time adjustment strategy:

[0035] Control objectives: ΔT_insp and ΔT_exp approach 0, and ΔA approaches 0;

[0036] Control algorithm: Multivariable PID controller: PID parameters are designed for the time deviation and amplitude deviation respectively.

[0037] The specific algorithm is:

[0038] Stim_adj = Kp * ΔT + Ki * ∫ΔT dt + Kd * d(ΔT) / dt

[0039] Music_adj = Kp_m * ΔA + Ki_m * ∫ΔA dt

[0040] Parameter tuning: The initial gains (Kp, Ki, Kd) are set through the trial-and-error method or the Ziegler-Nichols method.

[0041] Further, in the real-time adjustment process of step S3:

[0042] Inspiratory phase: Generate an ascending scale (C4 → G4), and the frequency linearly increases with the increase of the stimulation intensity;

[0043] Expiratory phase: Generate a descending scale (G4 → C4), and natural soundscapes (such as wind sounds) are superimposed to enhance the sense of relaxation.

[0044] Further, in step S5, the training data record includes storing respiratory parameters, stimulation settings, music types, and physiological indicators.

[0045] The beneficial effects of the present invention are as follows: The present invention provides a wearable music diaphragm pacemaker and its usage method, having the following advantages:

[0046] 1. Compared with traditional diaphragm pacemakers that mainly rely on electrical stimulation to passively enhance diaphragmatic contraction and patients need to actively cooperate with breathing training, in this application, through the real-time matching of the rhythm and tone changes of mindfulness music with electrical stimulation parameters, such as the tone rising during the inspiratory phase and the rhythm slowing down during the expiratory phase, a multi-sensory collaborative stimulation is formed, enhancing the patient's perception of the respiratory rhythm and active cooperation, thereby effectively improving the rehabilitation effect;

[0047] 2. Extract the respiratory cycle and tidal volume parameters through filtering and peak detection algorithms, calculate the deviations from the target rhythm (ΔT_insp, ΔT_exp, ΔA), and dynamically adjust the electrical stimulation intensity and frequency using PID or fuzzy logic control algorithms to form a closed-loop feedback, and optimize the target rhythm by combining historical data, which can avoid over-stimulation or ineffective treatment;

[0048] 3. Through the precise synchronization of music rhythm and electrical stimulation, activate the synergistic effect between the auditory cortex and the respiratory center of the brain, promote synaptic remodeling, and accelerate the recovery of phrenic nerve function;

[0049] 4. Integrate respiratory parameters, electrical stimulation responses, music feedback, and subjective fatigue scores to generate a visual report, providing a basis for precise adjustment by doctors.
