Electrical stimulation system that dynamically adjusts the stimulus signal

The invention provides an electrical stimulation system capable of dynamically adjusting a stimulation signal, in particular to a system for adjusting an electrical stimulation device stimulation signal according to different muscle group positions.

In the market, when using the electric stimulator, the user needs to select one of the modes built in the electric stimulator. When the electric stimulator receives the mode selected by the user, the control unit of the electric stimulator will be based on The mode selected by the user outputs a control signal to further set a stimulus signal output by the electrical stimulator. The user needs to attach the electric shock patch of the electric stimulator to the two ends of the user's muscle, so that the electric shock patch and the muscle form a conductive path, and then the stimulation signal output by the electrical stimulator passes through the conductive path to the user. The muscles are stimulated to cause the muscles to respond to the body by stimulation.

According to this, the conventional electrical stimulator, the output of the stimulation signal (current) is selected according to the plurality of sets of current output waveforms built in the electrical stimulator before use, so that the stimulation signal can be stabilized according to the user's setting. The ground output, therefore, the stimulus signal that the conventional electrical stimulator can output will be limited by the current waveform built into the electrical stimulator.

However, there are differences in the water content contained in the human muscles and the body impedance of different people. Therefore, conventional electrical stimulators provide a fixed output current waveform that does not produce the same stimulating effect on different muscle groups of different people or the same person. In detail, if the same current waveform is used to shock a user's calf muscle, the user's calf muscle will react due to the stimulation signal. If the current waveform is stimulated to the same user's thigh muscle, Because the user's body resistance and the water content of each muscle are different, the thigh muscles cannot be caused by the stimulation signal, or the thigh muscles are too large, causing damage to the thigh muscles. For electrical stimulation, it will cause Has a negative effect.

Furthermore, if the current waveform is stimulated to the calf muscle of another user, the other user may also have a limb reaction due to the stimulation signal due to the difference in the body resistance and the moisture content of the muscle group, or the stimulation signal. Too large, causing damage to the calf muscle of another user, also violates the original intention of electrical stimulation.

Therefore, as can be seen from the above, if the electrical stimulator only provides a fixed current waveform, so that the electrical stimulator outputs a stimulation signal to different positions or different human muscles according to a fixed current waveform, different results will be produced for use in electrical stimulation. When there is an indefinite factor, the user cannot accurately grasp the electrical stimulation when operating the electrical stimulator, and even cause muscle damage to the user.

Then, the user inputs the start signal of the execution program to the input unit 33 (such as the touch screen) on the mobile device 3, and transmits the start signal to the electrical stimulator 1 to cause the electrical stimulator 1 to generate the stimulation signal to the user. Perform electrical stimulation, record the user's elevation angle of the stimulation signal, store the stimulation signal and the elevation angle to the comparison table, and then, the screen of the mobile device 3 will display the visual guidance signal 321 (ie, display the football self-screen The top of the screen is dynamically dropped below the opposite side).

Further, referring to FIG. 5B, the screen of the mobile device 3 presents a picture 321 of the falling of the soccer ball. Since the user sees the soccer ball falling from the top to the bottom, the user instinct will drive the lower leg to kick up to participate in the game of playing soccer. Because the position sensor 2 composed of the angle meter will detect the change of the position of the user's lower leg as the game progresses, the detection signal 211 is generated according to the change of the position of the user's lower leg, and the detection signal 211 is transmitted to The mobile device 3 transmits the detection signal 211 to the server 4 via the Internet for storage, and provides the remote rehabilitation engineer to understand the user's electrical stimulation.

When the football moves, it will move up.

On the other hand, when the screen of the mobile device 3 indicates that the soccer ball falls to a height lower than one third of the path of the soccer fall, the angle detected by the position sensor 2 of the user is less than the first preset value. Because the first preset value corresponds to the second preset value, the mobile device 3 generates a control signal according to the comparison table, and transmits the control signal to the electrical stimulator 1, and the electrical stimulator 1 receives the control signal. After that, the current output unit 12 is driven to output the stimulation signal to the electric shock patch 5, and the user releases more stimulation energy to the user's calf muscles due to the stimulation signal, so that the calf muscle elevation angle is increased to actually achieve electrical stimulation.
