Description

Technical Field

[0001] The present application relates to the technical field of medical devices, and in particular to a genioglossus muscle stimulator and an output control method thereof. Background Art

[0002] Neuromuscular electrical stimulation (NMES) is a treatment that uses low-level current to target a single muscle or a group of muscles, which can cause local muscle or muscle group contraction, thereby improving muscle function and promoting healthy blood flow to the damaged muscle area. Apnea causes users to have poor sleep quality and affect their health.

[0003] In the prior art, the genioglossus muscle stimulator uses a smaller current and a lower frequency to stimulate the genioglossus muscle in order to make the user in the sleeping state more comfortable during the stimulation process. For example, the current is below 5mA and the frequency is between 5Hz and 150Hz. However, stimulating the genioglossus muscle with a smaller current is prone to insufficient stimulation and cannot open the airway, thereby failing to improve sleep apnea. Although increasing the current can keep the airway open, it is easy to cause the user's genioglossus muscle to twitch continuously and be unable to fall asleep, and the user's sleep quality is still poor.

[0045] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of the present invention. For ordinary technicians in this field, the present invention can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0046] As shown in the present invention and claims, unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular, but also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list, and the method or device may also include other steps or elements.

[0047] Although the present invention makes various references to certain modules in the system according to an embodiment of the present invention, any number of different modules can be used and run on a computing device and / or processor. The modules are only illustrative, and different aspects of the system and method can use different modules.

[0048] It should be understood that when a unit or module is described as being "connected," "coupled" to other units, modules, or blocks, it may refer to being directly connected or coupled, or communicating with other units, modules, or blocks, or there may be intermediate units, modules, or blocks, unless the context clearly indicates otherwise. The term "and / or" as used herein may include any and all combinations of one or more of the associated listed items.

[0049] The stimulation frequency generally affects skeletal muscle contraction, such as muscle fatigue and mild muscle contraction disorders. The contraction of human muscles is completed by the conduction of electrical signals released by human nerves, which is the most important factor in muscle contraction. If you want to excite the stimulated tissue, you must achieve a certain amount of stimulation, that is, a certain stimulation intensity, stimulation frequency, stimulation time, and a certain value of the time elasticity coefficient.

[0050] When the stimulation frequency is low, each stimulation will result in a single stimulus, because each time a new stimulus arrives, the entire process of a single stimulus caused by the previous stimulus is completed. When the stimulation frequency is low and the time interval between each stimulus exceeds the duration of a single muscle contraction, the muscle's response will be a series of single contractions.

[0051] In the prior art, the genioglossus muscle stimulator uses a small current to stimulate the genioglossus muscle, which is prone to insufficient stimulation and fails to open the airway, thereby failing to improve apnea. Although increasing the current can keep the airway open, it is easy to cause the user's genioglossus muscle to twitch continuously and be unable to fall asleep, and the user's sleep quality is still poor.

[0052] To solve this technical problem, Figure 1 As shown, an embodiment of the present invention provides a genioglossus muscle stimulator, including a controller 100, a signal generator 200 and an electrode contact 300, wherein the controller 100 is connected to the signal generator 200, and the signal generator 200 is connected to the electrode contact.

[0053] The controller 100 is used to control the signal generator 200 to generate a first electrical stimulation signal when the user is in a non-sleep state, and output the first electrical stimulation signal through the electrode contact 300; the frequency range of the first electrical stimulation signal is [1HZ, 500Hz], the current range is [0.1mA, 20mA], and the pulse width range is [10us, 500us].

[0054] The controller 100 is also used to control the signal generator 200 to generate a second electrical stimulation signal when the user is in a sleep state, and output the second electrical stimulation signal through the electrode contact 300; the frequency range of the second electrical stimulation signal is [1KHZ, 20KHZ], the current range is [0.1mA, 20mA], and the pulse width range is [10us, 500us].

[0055] The genioglossus muscle stimulator in this embodiment can generate a high-frequency, high-current second electrical stimulation signal when the user is sleeping. By increasing the frequency range and current range of the genioglossus muscle stimulator and the frequency of the second electrical stimulation signal of the genioglossus muscle stimulator, the tolerance of the genioglossus muscle to the current size can be improved under high-frequency current stimulation, thereby enabling the user to have better comfort and stimulation effect under a larger current, and also facilitating the user to fall asleep.

[0056] The second electrical stimulation signal in this frequency range exceeds the generation of the action point or each stimulation falls within the shortened period caused by the previous stimulation, so high-frequency stimulation will not produce corresponding twitching, or the twitching amplitude is small, which improves the comfort of nighttime wearing and avoids the fatigue caused by the large twitching of low-frequency stimulation. At the same time, high-frequency stimulation can also shorten the use time of the genioglossus muscle stimulator.

[0057] The genioglossus muscle stimulator outputs a second electrical stimulation signal with high frequency and high current. During use, it can not only enhance the myoelectric capacity, but also reduce muscle contraction (avoid muscle contraction) by matching the corresponding high frequency to the corresponding high current, thereby improving the muscle tension of the genioglossus muscle and avoiding muscle fatigue caused by muscle contraction, while improving the wearing comfort of the user.

[0058] The genioglossus muscle stimulator in this embodiment has two working modes. The first mode is to generate a low-frequency first electrical stimulation signal when the user is not sleeping, so as to train the user's genioglossus muscle and reduce the fat content of the genioglossus muscle; the second mode is to generate a high-frequency second electrical stimulation signal when the user is sleeping, so as to stimulate the genioglossus muscle to open the airway for breathing, avoid apnea, and allow the user to rest comfortably.

[0059] Sleep apnea usually occurs at night, and the myoelectric signal of the genioglossus muscle of users with sleep apnea is generally low, and is also correlated with the sleep period. Since the genioglossus muscle stimulator in the prior art uses a fixed second electrical stimulation signal, and the myoelectric signal gradually decreases during the user's sleep, the prior art cannot ensure the stability of the myoelectric signal, resulting in poor use effect.

[0060] To solve this technical problem, the genioglossus muscle stimulator proposed in the embodiment of the present invention further includes a signal collector for collecting a first electromyographic signal of a user in a non-sleeping state, or collecting a second electromyographic signal of a user in a sleeping state. Figure 2 As shown, the controller 100 includes a model building module 102, which is used to build a first electromyographic signal model based on the first electromyographic signal; a model updating module 104, which is used to update the first electromyographic signal model based on the second electromyographic signal to obtain a second electromyographic signal model; a signal compensation module 106, which is used to determine an electromyographic compensation signal based on the second electromyographic signal and the second electromyographic signal model; and a signal control module 108, which is used to control the signal generator 200 to output the corresponding second electrical stimulation signal based on the electromyographic compensation signal.

[0061] In this embodiment, taking into account that different users have different electromyographic levels in the state of respiratory obstruction, by constructing a first electromyographic signal model corresponding to the user, the accuracy of the second electrical stimulation signal corresponding to the output of the genioglossus muscle stimulator can be improved to improve the use effect.

[0062] In addition, based on the second electromyographic signal and the second electromyographic signal model, an electromyographic compensation signal is determined, and based on the electromyographic compensation signal, the signal generator 200 is controlled to output a corresponding second electrical stimulation signal, thereby ensuring the stability of the electromyographic signal of the user during sleep.

[0063] The model building module 102 includes: a feature acquisition module, which is used to extract features from the first electromyographic signal to obtain feature parameters of the first electromyographic signal; and a model building submodule, which is used to generate the first electromyographic signal model based on the feature parameters.

[0064] The characteristic parameters include time domain characteristics and frequency domain characteristics, wherein the time domain characteristics include waveform, intensity, phase and other parameters.

[0065] When the user is in a non-sleeping state, the electromyographic signal acquisition module of the genioglossus muscle stimulator acquires the first electromyographic signal of the genioglossus muscle, performs feature extraction on the first electromyographic signal, obtains feature parameters of the first electromyographic signal, and obtains the first electromyographic signal model of the user by learning the feature parameters.

[0066] By constructing the first electromyographic signal model corresponding to the user, the accuracy of the second electrical stimulation signal outputted by the genioglossus muscle stimulator can be improved. The first electromyographic signal model can be used for genioglossus muscle tension training in a normal state of the user.

[0067] In some embodiments, Figure 3 As shown, the controller 100 also includes: a signal enhancement module 110, which is used to perform signal enhancement on the first electromyographic signal model to obtain a third electromyographic signal; the signal control module 108 controls the signal generator 200 to output a corresponding first electrical stimulation signal based on the third electromyographic signal.

[0068] During the genioglossus muscle tension training, the user needs to enhance the electromyographic signal. In the above embodiment, the first electromyographic signal model has been obtained, and the third electromyographic signal is obtained after signal enhancement. Based on the third electromyographic signal, the signal generator 200 is controlled to output the corresponding first electrical stimulation signal, so that the electromyographic signal collected by the user during the genioglossus muscle tension training reaches the third electromyographic signal, and the electromyographic signal is enhanced to help the user improve the tongue muscle tension. Since the third electromyographic signal is obtained by signal enhancement of the first electromyographic signal model, it can meet the requirements of improving the matching with the user's own electromyographic signal.

[0069] The characteristic parameters of the first electromyographic signal model include frequency , amplitude , and phase , the frequency of the enhanced third electromyographic signal , amplitude , and phase The following relations are satisfied:

[0070]

[0071] in, n is the training frequency coefficient, m is the strength coefficient, C For training intensity, k is the phase shift coefficient, is the phase offset.

[0072] Since the user has different electromyographic signals in a normal state and a sleeping state, the first electromyographic signal model needs to be updated in order to make the first electromyographic signal model suitable for the nighttime sleeping stage.

[0073] During the nighttime sleep stage, the model updating module 104 fuses and updates the second electromyographic signal and the first electromyographic signal model to obtain a second electromyographic signal model. The second electromyographic signal model satisfies the following relationship:

[0074]

[0075] in, p represents the model transformation empirical function, t Indicates time, s represents the second electromyographic signal, h Represents the first electromyographic signal model.

[0076] The signal compensation module 106 compares the second electromyographic signal with the second electromyographic signal model to determine whether the second electromyographic signal is an abnormal electromyographic signal; if so, determines an electromyographic compensation signal based on the abnormal electromyographic signal and the second electromyographic signal model.

[0077] During the nighttime sleep stage, the user's second electromyographic signal is monitored, and the collected second electromyographic signal is compared with the second electromyographic signal model. If the difference between the two is greater than a threshold, the second electromyographic signal is determined to be an abnormal electromyographic signal. The abnormal electromyographic signal is compensated using the second electromyographic signal model to obtain an electromyographic compensation signal.

[0078] In some embodiments, the electromyographic compensation signal satisfies the following relationship:

[0079]

[0080] in, represents the myoelectric compensation signal, Indicates abnormal electromyographic signal. is the compensation experience function.

[0081] The signal compensation module 106 controls the parameters of the second electrical stimulation signal output by the signal generator 200 based on the electromyographic compensation signal, so that the second electromyographic signal of the user collected again in the sleeping state conforms to the second electromyographic signal model.

[0082] The parameters include frequency, current, pulse width, duty cycle, etc.

[0083] The user's normal breathing is restored by controlling the genioglossus muscle stimulator to output a second electrical stimulation signal.

[0084] Figure 4 FIG. 1 is a schematic diagram of the overall flow of the output control method of the genioglossus muscle stimulator in an exemplary embodiment of the present application. Figure 4 As shown, the method comprises the following steps:

[0085] Step ①, using a signal acquisition module to collect a first electromyographic signal of the genioglossus muscle of the user in a non-sleeping state;

[0086] Step ②, using the model building module 102 to build a first electromyographic signal model based on the first electromyographic signal;

[0087] Step ③, using the signal enhancement module 110 to enhance the signal of the first electromyographic signal model to obtain a third electromyographic signal;

[0088] Step ④, based on the third electromyographic signal, using the signal control module 108 to control the signal generator 200 to output the corresponding first electrical stimulation signal to perform genioglossus muscle tension training;

[0089] Step 5, using the signal acquisition module to collect the second electromyographic signal of the user in the sleeping state;

[0090] Step ⑥, using the model updating module 104 to update the first electromyographic signal model based on the second electromyographic signal to obtain a second electromyographic signal model;

[0091] Step 7, using the signal compensation module 106 to determine an electromyographic compensation signal based on the second electromyographic signal and the second electromyographic signal model;

[0092] Step ⑧, using the signal control module 108 to control the signal generator 200 to output a corresponding second electrical stimulation signal based on the electromyographic compensation signal.

[0093] Based on the above hardware embodiment, Figure 5 As shown, the embodiment of the present application also proposes an output control method of a genioglossus muscle stimulator, the method comprising:

[0094] S502: Control the signal generator to generate a first electrical stimulation signal when the user is in a non-sleeping state, and output the first electrical stimulation signal through the electrode contacts.

[0095] The frequency range of the first electrical stimulation signal is [1HZ, 500Hz], the current range is [0.1mA, 20mA], and the pulse width range is [10us, 500us].

[0096] S504: Control the signal generator to generate a second electrical stimulation signal when the user is in a sleeping state, and output the second electrical stimulation signal through the electrode contacts.

[0097] The frequency range of the second electrical stimulation signal is [1KHZ, 20KHZ], the current range is [0.1mA, 20mA], and the pulse width range is [10us, 500us].

[0098] In this embodiment, by increasing the frequency range and current range of the genioglossus muscle stimulator and increasing the frequency of the second electrical stimulation signal of the genioglossus muscle stimulator, the tolerance of the genioglossus muscle to the current size can be improved under high-frequency current stimulation, thereby enabling the user to have better comfort and stimulation effects under larger currents and also making it easier for the user to fall asleep.

[0099] The genioglossus muscle stimulator can generate a first electrical stimulation signal when the user is not sleeping to train the user's genioglossus muscle, and can also generate a second electrical stimulation signal when the user is sleeping to open the user's airway so that the user can rest comfortably.

[0104] S608: Based on the electromyographic compensation signal, control the signal generator to output a corresponding second electrical stimulation signal.

[0105] In this embodiment, taking into account that different users have different electromyographic levels in the state of respiratory obstruction, by constructing a first electromyographic signal model corresponding to the user, the accuracy of the second electrical stimulation signal corresponding to the output of the genioglossus muscle stimulator can be improved to improve the use effect.

[0106] In addition, based on the second electromyographic signal and the second electromyographic signal model, an electromyographic compensation signal is determined, and based on the electromyographic compensation signal, the signal generator is controlled to output a corresponding second electrical stimulation signal, thereby ensuring the stability of the electromyographic signal of the user during sleep.
