The intervention of electronic technology has greatly promoted the development of electrotherapy products. At present, there are many electrical stimulation treatment instruments on the market that can simulate various traditional techniques to treat patients. However, in the rehabilitation treatment of pelvic floor muscles, due to the complex anatomical structure of the pelvic floor muscles and the different pathological conditions of each patient, it is necessary not only to personalize the signal intensity used for pelvic floor muscle rehabilitation treatment, but also to ensure that muscle groups in different parts can be properly stimulated to achieve the best rehabilitation effect. Prolonged or excessively high-intensity stimulation may cause muscle fatigue or damage. Therefore, the signal intensity should be designed to avoid overstimulation of muscle tissue and prevent muscle fatigue while effectively treating. Especially in multi-channel stimulation, how to ensure that the signal intensity between channels is uniform and synchronized to avoid overstimulation differences between different muscle groups and adjust the muscles in different parts to participate in the rehabilitation process together is a technical problem that needs to be solved urgently.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

For example, some operations / steps may also be decomposed, combined or partially merged, so the actual execution order may change according to actual conditions.

As used in this application specification and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include plural forms.

[0066] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0067] The technical solution provided by this application will be described in detail below with reference to the accompanying drawings.

[0068] See also Figure 1 , Figure 1 A schematic diagram of the implementation flow of the multi-channel signal control method provided in the embodiment of the present application. The multi-channel signal control method is implemented by a multi-channel signal control device, and the software and / or hardware included in the multi-channel signal control device can execute corresponding steps to output multi-channel electrical stimulation signals, and the signal strength between the corresponding channels is kept uniform and synchronized to avoid excessive stimulation differences between different muscle groups and adjust the muscles in different parts to participate in the rehabilitation process together. The multi-channel control device can be well applied to the rehabilitation treatment of pelvic floor muscles. Among them, the multi-channel signal control device includes but is not limited to a computer, a terminal, a therapeutic device or a repair device, etc.

[0069] Depend on Figure 1 It can be seen that the multi-channel signal control method includes steps S101 to S105. The details are as follows:

[0070] S101: Control the pulse signals on multiple channels and synchronously generate electrical stimulation signals to each channel.

[0071] The device outputs pulse signals of multiple channels through a pulse timing generation component, and mixes and encodes the pulse signals of each channel with the preset basic frequencies corresponding to each channel to form the initial electrical stimulation signals of each channel; the initial electrical stimulation signals of each channel are delayed according to the preset delays corresponding to each channel, and the electrical stimulation signals are output synchronously to each channel after the delay. The pulse signals of multiple channels are generated through a pulse timing generation component, and mixed and encoded in combination with the preset basic frequencies, so that the device can flexibly generate electrical stimulation signals that meet different rehabilitation needs, and after the delay adjustment of the original electrical stimulation signals of each channel, the electrical stimulation signals of all channels can be synchronized. Among them, the preset basic frequencies corresponding to each channel can be flexibly set in advance according to rehabilitation needs.

[0072] S102: Collect the electrical stimulation signal and synchronous trigger time of each channel at the current moment in real time.

[0073] S103: respectively determining the first intensity of the electrical stimulation signal of each channel at the current moment, and determining the second intensity of the electrical stimulation signal of each channel at the next moment according to the first intensity.

[0074] Determine the second intensity of the electrical stimulation signal of each channel at the next moment according to the first intensity of the electrical stimulation signal of each channel at the current moment, including: calculating the average value of the first intensity of the electrical stimulation signal of all channels at the current moment; respectively calculating the deviation between each first intensity and the average value; determine the second intensity of each electrical stimulation signal at the next moment based on a preset adjustment coefficient according to the deviation between each first intensity and the average value.

[0075] Exemplarily, according to the deviation between the first intensity of the electrical stimulation signal of each channel at the current moment and the average value, the second intensity of the electrical stimulation signal of each channel at the next moment is determined based on the preset adjustment coefficient, including: matching the preset adjustment coefficient adapted for each channel according to the deviation between the first intensity of the electrical stimulation signal of each channel at the current moment and the average value; respectively calculating the product of the deviation and the preset adjustment coefficient adapted for each channel; and subtracting the products from the first intensity of the electrical stimulation signal of each channel at the current moment to obtain the second intensity of the electrical stimulation signal of each channel at the next moment.

[0076] Among them, the preset adjustment coefficient is greater than 0 and less than or equal to 1. Specifically, when the deviation between the first intensity of the electrical stimulation signal of a channel and the average value is large, the preset adjustment coefficient adapted to the channel is also large, and vice versa, the preset adjustment coefficient adapted to the channel is also small. That is to say, as the deviation values ​​of each channel are different, the preset adjustment coefficient with a variation range of 0 to 1 will be automatically matched to achieve dynamic and progressive adjustment of the intensity of each channel signal based on the adjustment coefficient, ensuring that the amplitude of the signal strength adjustment will not be too large, making the change of signal strength more stable, which is conducive to maintaining stable stimulation of muscle groups and avoiding muscle discomfort or damage caused by drastic changes in signal strength.

[0077] S104: Based on preset parameters, modulate the transmission time and phase of the electrical stimulation signal of each channel.

[0078] The preset parameters include a preset basic frequency corresponding to each channel and a preset transmission delay corresponding to each channel.

[0079] Exemplarily, based on preset parameters, the transmission time and phase of each electrical stimulation signal are adjusted, including: calculating the current phase of the electrical stimulation signal corresponding to each channel according to the preset basic frequency corresponding to each channel and the current phase offset of the electrical stimulation signal of each channel; determining the adjustment time of each channel according to the synchronous trigger time and the preset transmission delay corresponding to each channel; determining the adjustment phase of each channel according to the synchronous trigger time and the basic frequency; adjusting the transmission time of each electrical stimulation signal according to the adjustment time of each channel, and adjusting the phase of each electrical stimulation signal according to the adjustment phase of each channel.

[0080] Specifically, assuming that the phase of the electrical stimulation signal corresponding to each channel at the current moment is φ(t), then:

[0081] Among them, 2πft is the phase progress of the electrical stimulation signal of the corresponding channel at the current time t, θ is the current phase offset of the electrical stimulation signal of the corresponding channel, and f is the preset basic frequency corresponding to each channel.

[0082] For each channel i, assume that the corresponding adjustment time is T i , then: T i =T s -(Δt i -Δt min )

[0083] Among them, T s is the synchronization trigger time, Δt i is the preset transmission delay of channel i, Δt min It is the smallest transmission delay among all channels.

[0084] Δt i -Δt min The extra delay of channel i is calculated, which is the extra time required for channel i compared to the fastest channel. The above adjustment time can compensate for the delay of different channels and ensure that the signals of all channels can be output at the same time.

[0085] The adjustment phase of each channel is determined according to the synchronization trigger time and the basic frequency, including: for any channel, according to the synchronization trigger time and the basic frequency, calculating the phase angle of the channel at the synchronization trigger time; according to the current phase and the phase angle at the synchronization trigger time, calculating the adjustment phase of the channel.

[0086] Specifically, for channel i, the phase angle of the channel at the synchronization trigger time is assumed to be but:

[0087]

[0088] Among them, f i is the fundamental frequency of channel i.

[0089] Corresponding to the adjustment phase of channel i It can be expressed as:

[0090] Among them, θ i is the current phase of the electrical stimulation signal corresponding to i.

[0091] The phase angle of the channel at the synchronization trigger time is calculated based on the synchronization trigger time and the basic frequency, and then the adjustment phase of the channel is calculated based on the current phase and the phase angle at the synchronization trigger time. The adjustment phase is used for subsequent signal phase correction to ensure that the signals of all channels are output synchronously at the synchronization trigger time point.

[0092] S105: If the transmission time and phase of the electrical stimulation signals of each channel are consistent, the electrical stimulation signals of each channel are output as target electrical stimulation signals.

[0093] Through the above analysis, it can be known that the multi-channel signal control method provided in the embodiment of the present application includes: controlling the pulse signals on multiple channels to synchronously generate electrical stimulation signals to each channel; collecting the electrical stimulation signals of each channel at the current moment in real time; determining the strength of each electrical stimulation signal at the next moment according to the strength of each electrical stimulation signal at the current moment; adjusting the transmission time and phase of each electrical stimulation signal based on preset parameters; if the transmission time and phase of each electrical stimulation signal remain consistent, outputting each electrical stimulation signal as a target electrical stimulation signal. By determining the strength of the electrical stimulation signal of each channel at the next moment according to the strength of the electrical stimulation signal of each channel at the current moment, so as to achieve uniform signal strength of each channel, and by adjusting the transmission time and phase of each electrical stimulation signal based on preset parameters, the synchronization of the signals of each channel can be achieved.
