Description

Technical Field

[0001] The present application relates to the field of consumer electronic products, and in particular to a massage device. Background Art

[0002] A fascia massage gun is a soft tissue rehabilitation tool used to relieve muscle pain and provide relaxation massage to various parts of the body. The gun's working principle is that its internal high-speed motor drives the massage head to vibrate, impacting the muscle tissue. The high-frequency vibrations of the massage head penetrate deep into the muscles, reducing localized tissue tension, pain in the joints, and promoting blood circulation.

[0003] Although existing fascia guns can be used for muscle massage and pain relief, they have a single function and can only hit and massage parts of the human body through several massage heads or several inherent massage modes. They cannot detect the physiological parameters of the human body, resulting in users being unable to intuitively understand their physiological state. Summary of the Invention

[0004] The embodiment of the present application provides a massage device that can detect physiological parameters of the human body, so that the user can intuitively understand the physiological state.

[0005] The massage device of the embodiment of the present application includes a host and a massage head; the host includes a host housing, a driving device and an algorithm module, the algorithm module is located in the host housing, and the driving device is installed in the host housing; the massage head includes a massage head housing, a detection module connected to the massage head housing, and a signal processing module located in the massage head housing; the massage head housing is detachably connected to the driving device so that the massage head can move under the drive of the driving device; the detection module is used to detect physiological parameters of the human body; the signal processing module is electrically connected to the detection module, and the signal processing module is used to preprocess the physiological parameters detected by the detection module and generate a preprocessing signal, which carries information about the physiological parameters; the algorithm module is used to process the preprocessing signal generated by the signal processing module to determine the degree of muscle fatigue.

[0006] In this solution, the host is the main control part of the massage device, and the host can control the massage head to perform detection and massage. The algorithm module is used for data processing and calculation, and can evaluate the physiological condition of the human body based on the built-in algorithm. The algorithm module includes but is not limited to a processor, a controller, or a circuit with data processing and calculation functions. The drive device is used to generate mechanical movement to output movement. The drive device can be assembled from several components, which may include a motor for providing driving force and a mechanism for transmission. A portion of the drive device can be housed in the host housing, and another portion can be exposed from the host housing. Alternatively, the entire area of ​​the drive device can be located within the host housing.

[0007] In this solution, the detection module includes at least one functional element. The detection module can be located on the surface of the massage head housing, or at least partially within the housing. The detection module can detect physiological parameters such as muscle oxygen saturation, blood oxygen saturation, heart rate, lactate level, electromyographic signals, electrocardiographic signals, and human body impedance. The signal processing module is used to preprocess the physiological signals detected by the detection module (e.g., filtering, noise reduction, amplification, etc.) to generate a preprocessed signal containing information about the physiological parameters.

[0008] In this solution, the algorithm module can process and calculate the preprocessed signal according to the built-in algorithm, thereby evaluating the muscle fatigue, that is, detecting the muscle fatigue.

[0009] Therefore, by integrating a detection module and a signal processing module into the massage head, this solution enables the massage head to detect physiological parameters of the human body. The algorithm module within the main unit processes the measured physiological parameters to determine the degree of muscle fatigue. Therefore, the massage device of this solution can detect physiological parameters of the human body, allowing the user to intuitively understand their physiological state.

[0010] In one implementation, the detection module includes a positive electrode and a negative electrode provided on the surface of the massage head shell, the positive electrode and the negative electrode are separated and insulated, the positive electrode and the negative electrode are electrically connected to the signal processing module, and the positive electrode and the negative electrode are used to detect the human body's electromyographic signals and / or human body impedance signals.

[0011] In this implementation, the specific positions of the positive electrode and the negative electrode on the surface of the massage head shell can be designed as needed. For example, in order to facilitate contact with human skin, the positive electrode and the negative electrode can be arranged on the surface of the massage head shell at one end away from the main unit. The positive electrode and the negative electrode are used to contact human skin to collect human bioelectric signals, such as at least one of electromyographic signals, electrocardiographic signals and human body impedance. By integrating the positive and negative electrodes on the massage head, the bioelectric signals of the human body can be detected; by processing the bioelectric signals through the algorithm module in the main unit, the muscle fatigue of the human body can be determined. In addition, through the set of electrodes including the positive electrode and the negative electrode, simultaneous electromyographic signal detection and human body impedance detection can be achieved, which enables the massage device to have different detection modes; and by comprehensively processing multiple bioelectric signals through the algorithm module, the accuracy of the muscle fatigue assessed by the massage device can be improved.

[0012] In one implementation, the detection module includes a light source and a photosensor, which are arranged at intervals and are both electrically connected to the signal processing module; the light source is used to emit a light signal that can penetrate the skin to the human body; the photosensor is used to sense the light signal emitted from the skin and generate an electrical signal for characterizing the muscle oxygen saturation of the human body.

[0013] In this implementation, the light source can be a light-emitting diode (LED), and the photosensor can be a photodiode. Light from the light source penetrates the skin, is scattered and absorbed by human tissue, and then exits the skin and is received by the photosensor. An algorithm module processes the electrical signal sensed by the photosensor to determine muscle oxygen saturation, which can then be used to assess muscle fatigue.

[0014] In one implementation, the light source includes a first light source and a second light source, the first light source and the second light source are arranged at intervals, and the distance between the first light source and the photosensor is greater than the distance between the second light source and the photosensor; the first light source and the photosensor are used to detect muscle oxygen saturation, and the second light source and the photosensor are used to detect blood oxygen saturation.

[0015] In this implementation, the first light source and the photosensor form a first optical signal detection channel, and the second light source and the photosensor form a second optical signal detection channel. In the optical signal detection channel, light is emitted from the light source and penetrates the skin. After being scattered and absorbed by human tissue, it is emitted from the skin and received by the photosensor. According to practical rules, in the first optical signal detection channel where the distance between the first light source and the photosensor is larger, the light penetrates the skin to a deeper depth and can penetrate into muscle tissue. Therefore, the first optical signal detection channel can be used to detect muscle oxygen saturation; in the second optical signal detection channel where the distance between the second light source and the photosensor is smaller, the light penetrates the skin to a shallower depth and can penetrate into skin tissue (for example, reaching the dermis). Therefore, the second optical signal detection channel can be used to detect blood oxygen saturation.

[0016] In one implementation, the massage head housing includes a first massage column, a second massage column, and a connecting portion. The first and second massage columns are connected to the same side of the connecting portion, and there is a gap between the first and second massage columns. The end of the connecting portion remote from the first massage column is detachably connected to the drive device. The positive electrode is located on the surface of the first massage column remote from the connecting portion, and the negative electrode is located on the surface of the second massage column remote from the connecting portion. This implementation, through the design of the massage head housing, allows the massage head to have a Y-shaped structure, suitable for use on corresponding parts of the human body, ensuring a better user experience for the massage device.

[0017] In one implementation, the first massage column and the second massage column both have a connection structure; the detection module includes a first wet electrode and a second wet electrode; the first wet electrode is detachably connected to the connection structure of the first massage column and is electrically connected to the signal processing module; the second wet electrode is detachably connected to the connection structure of the second massage column and is electrically connected to the signal processing module; the first wet electrode and the second wet electrode are used to detect myoelectric signals and / or human body impedance signals, wherein when the first wet electrode and the second wet electrode are performing detection, the positive electrode and the negative electrode are idle.

[0018] In this implementation, the connection structure is used to achieve a detachable connection between the wet electrode and the massage column, and the connection structure can be, for example, a socket. The first wet electrode and the second wet electrode have good conductive properties, which can ensure the quality of collecting bioelectric signals from the human body. The first wet electrode and the second wet electrode can be composed of a connector, an adhesive, a conductive lining cloth, and a hydrogel conductive adhesive layer, and can make good adhesive contact with the surface of the human body through the hydrogel conductive adhesive layer. The first wet electrode and the second wet electrode can have the functions of the positive electrode and the negative electrode mentioned above, for example, the first wet electrode and the second wet electrode are used to detect the myoelectric signals and / or human body impedance signals of the human body. The first wet electrode and the second wet electrode can be used to replace the positive electrode and the negative electrode, respectively. By designing a connection structure on the massage head, the massage head can be expanded to install wet electrodes, which can improve the detection accuracy of the massage equipment.

[0019] In one implementation, the massage head housing includes a massage disc and a connecting portion, the massage disc being connected to one end of the connecting portion; the connecting portion being detachably connected to the drive device; and the detection module being located on a surface of the massage disc distal from the connecting portion. The positive electrode, the negative electrode, the light source, and the photosensor are spaced apart from one another. This implementation, through the design of the massage head housing, allows the massage head to have a flattened shape, adaptable to various areas of the human body, and ensuring a superior user experience.

[0020] In one implementation, the host includes a first interface provided in the host housing, and the first interface is electrically connected to the algorithm module; the massage head includes a second interface connected to the massage head housing, the second interface is electrically connected to the signal processing module, and the second interface is detachably connected to the first interface.

[0021] In this implementation, the second interface and the first interface are both electrical connection interfaces. Through the second interface and the first interface, the massage head and the host can be connected by wire to achieve signal transmission between the massage head and the host.

[0022] In one implementation, the massage head includes a first Bluetooth module disposed within the massage head housing, the first Bluetooth module being electrically connected to the signal processing module; the host computer includes a second Bluetooth module disposed within the host computer housing, the second Bluetooth module being electrically connected to the algorithm module; the first Bluetooth module is configured to transmit the pre-processed signal to the second Bluetooth module, and the second Bluetooth module is configured to transmit the received pre-processed signal to the algorithm module. In this implementation, the massage head and the host computer can be wirelessly connected via the first and second Bluetooth modules, enabling signal transmission between the massage head and the host computer.

[0023] In one implementation, the massage head includes a power module housed within the massage head housing. The power module is used to power the detection module, signal processing module, positive electrode, negative electrode, wet electrode, and other components within the massage head. This allows the massage head to be self-powered, eliminating the need for power from the main unit. This saves power to the main unit and improves its battery life.

[0024] In one implementation, the host includes a button installed on the host housing, the button has conductive properties, and the button, the positive electrode, and the negative electrode are used together to detect electrocardiogram signals of a human body.

[0025] In this implementation, the buttons can serve as function buttons, such as a power button or an operating mode selection button. The buttons on the massage head can also function as a third electrode. When the positive and negative electrodes contact a human body part, the third electrode can contact the human hand, thereby forming a lead circuit and enabling ECG signal acquisition. By reusing the functions of the buttons, the structural integration of the massage device can be enhanced, making the device more compact and lightweight. It also facilitates ECG signal detection for the user, improving the user experience.

[0027] In this implementation, the buttons can serve as functional buttons, such as a power button or an operating mode selection button.

[0028] In one implementation, the main unit includes an indicator light mounted on the main unit housing. In this implementation, the indicator light may be partially exposed from the main unit housing, or the indicator light may be completely contained within the main unit housing, but the indicator light may be emitted from the main unit housing. The indicator light may indicate the operating status of the massage device through different lighting modes under the control of internal circuitry. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The following embodiments of this application provide a massage device, including but not limited to a fascia gun, a muscle massager, a cervical massager, a handheld massage gun, and a joint massager. The massage device comprises a main unit and at least one massage head, which is detachably connected to the main unit. The massage device can detect physiological parameters of the human body, assess the body's physiological condition based on the detection results, and provide intelligent massage. This will be described in detail below.

[0039] For example Figure 1 、 Figure 2 and Figure 3 As shown, the massage device 10 includes a main unit 12 and a massage head 11, which is detachably connected to the main unit 12. The main unit 12 is the main control part of the massage device 10, and the main unit 12 can drive the massage head 11 to move so that the massage head 11 massages the human body.

[0040] like Figure 3 As shown, the host 12 may include a host housing 123, and an indicator light 121, a button 122, a button 124, a button 125, a drive device 126, and a first interface 127 installed in the host housing 123. An algorithm module may also be installed in the host housing 123.

[0041] The structure of the host housing 123 can be designed as needed and is not limited in this embodiment.

[0042] The indicator light 121 may be partially exposed outside the main body housing 123, or it may be completely contained within the main body housing 123, while still emitting light from the indicator light 121. The number of indicator lights 121 may be designed as needed, for example, one or more. Under the control of internal circuitry, the indicator light 121 can indicate the operating status of the massage device 10 through various illumination modes. For example, the indicator light 121 may flash, change brightness, or otherwise indicate the status of the measurement process.

[0043] Each of buttons 122, 124, and 125 may have a portion located within the main housing 123, while the remaining portion may be exposed. The location and function of each button can be customized as needed. For example, button 122 may be located at the top of the main housing 123 along with indicator light 121, and may function as a power button. Buttons 124 and 125 may be located on the cylindrical side of the main housing 123, and may function as function buttons, such as buttons for selecting the operating mode of the massage device 10.

[0044] In this embodiment, the number of buttons can be designed as needed and is not limited to three. A single button can also integrate at least two functions. For example, button 122 can serve as both a power switch and an operating mode confirmation function. Alternatively, button 124 or button 125 can be conductive and serve as a third electrode for measuring electrocardiogram signals (described below).

[0045] The drive device 126 is used to generate the mechanism movement to output the movement. The drive device 126 can be assembled from several parts, which may include a motor for providing driving force and a mechanism for transmission. The specific structure of the drive device 126 can be designed as needed and is not limited in this embodiment. A part of the drive device 126 can be housed in the main body housing 123, and another part can be exposed from the main body housing 123, for example Figure 1 and Figure 2 The portion of the drive device 126 exposed outside the main body housing 123 is shown. Alternatively, the entire drive device 126 can be located within the main body housing 123.

[0046] The first interface 127 is an electrical connection interface for realizing signal transmission between the massage head 11 and the main unit 12. The structure of the first interface 127 can be designed as needed and is not limited in this embodiment.

[0047] The algorithm module is used for data processing and calculation, and can assess the physiological condition of the human body based on a built-in algorithm. The algorithm module includes, but is not limited to, a processor, a controller, or a circuit capable of data processing and calculation. The algorithm module is electrically connected to the first interface 127 to receive signals transmitted by the massage head 11 through the first interface 127.

[0048] like Figure 1 、 Figure 2 and Figure 4 As shown, the massage head 11 may include a massage head housing 111, a second interface 117, a positive electrode 112, a first light source 113, a second light source 114, a photosensor 115, and a negative electrode 116. The massage head housing 111 may also include a signal processing module and a power supply module.

[0049] The structure of the massage head housing 111 can be designed as needed, and this embodiment does not limit it. For example, the massage head housing 111 can be roughly mushroom-shaped. The massage head housing 111 can be detachably connected to the drive device 126 of the host 12. Figure 2 As shown, the end of the massage head housing 111 with a smaller diameter can be detachably connected to the portion of the driving device 126 exposed from the main body housing 123.

[0050] Alternatively, if the drive device 126 is completely located in the main body housing 123, the smaller diameter end of the massage head housing 111 can extend into the main body housing 123 and be detachably connected to the drive device 126. In this case, the massage head housing 111 is also detachably connected to the main body housing 123.

[0051] After the massage head housing 111 is connected to the driving device 126, it can move under the drive of the driving device 126 to massage the human body. Since the connection between the massage head housing 111 and the driving device 126 can be detached, it is convenient to replace and install a variety of massage heads to fully meet massage needs.

[0052] The second interface 117 is an electrical connection interface for signal transmission between the massage head 11 and the main unit 12. The structure of the second interface 117 can be designed as needed and is not limited in this embodiment. When the massage head housing 111 is connected to the drive device 126 of the main unit 12, the second interface 117 also forms a detachable connection with the first interface 127 of the main unit 12. The second interface 117 is electrically connected to the signal processing module.

[0053] Both the positive electrode 112 and the negative electrode 116 can be disposed on the surface of the massage head housing 111. Illustratively, the positive electrode 112 and the negative electrode 116 can be located on the end of the massage head housing 111 away from the main unit 12, so as to contact human skin. A gap can be formed between the positive electrode 112 and the negative electrode 116, providing insulation between them. The shapes of the positive electrode 112 and the negative electrode 116 can be designed as desired.

[0054] Both the positive electrode 112 and the negative electrode 116 are used to collect bioelectric signals from the human body, such as electromyographic signals, electrocardiographic signals, and body impedance. When collecting electromyographic and electrocardiographic signals, the positive electrode 112 and the negative electrode 116 do not need to be pre-energized. When collecting body impedance (body impedance can be used to assess body fat and water content in parts of the human body), a voltage needs to be applied to the positive electrode 112 and the negative electrode 116. The area of ​​the positive electrode 112 and the negative electrode 116 can be maximized to improve the quality of physiological signal collection. In this embodiment, the positive electrode 112 and the negative electrode 116 are used as a set of electrodes to detect both electromyographic and electrocardiographic signals and body impedance. Of course, this requires the massage device 10 to operate in different detection modes (the detection modes will be described below).

[0055] The positive electrode 112 and the negative electrode 116 are both electrically connected to the signal processing module in the massage head housing 111 .

[0056] In this embodiment, the positive electrode 112 and the negative electrode 116 can both be dry electrodes fixed on the massage head housing 111 .

[0057] In other embodiments, the massage head 11 may further include a wet electrode interface, which is electrically connected to the signal processing module. The massage head housing 111 may further include a connection structure for connecting a wet electrode, which can be detachably connected to the massage head 11 via the connection structure and electrically connected to the massage head 11 via the wet electrode interface.

[0058] The wet electrode can be composed of, for example, a connector, adhesive, a conductive lining, and a hydrogel conductive adhesive layer. The good adhesive contact between the hydrogel conductive adhesive layer and the human body surface can effectively reduce the contact resistance between the electrode and the human body, so that the wet electrode has good conductive properties and can ensure the quality of the collection of bioelectric signals from the human body. There can be two wet electrodes, respectively referred to as the first wet electrode and the second wet electrode. The first wet electrode and the second wet electrode are both connected to the massage head 11 through a connecting structure and a wet electrode interface. The first wet electrode and the second wet electrode are used to replace the positive electrode 112 and the negative electrode 116, respectively. When the first wet electrode and the second wet electrode are used to contact the human body for detection, the positive electrode 112 and the negative electrode 116 will not contact the human body, and the positive electrode 112 and the negative electrode 116 are idle.

[0059] In this embodiment, when collecting ECG signals, the button 124 or button 125 on the massage head 11 can serve as a third electrode, the positive electrode 112 and the negative electrode 116 (or the first wet electrode and the second wet electrode) contact the human body part, and the third electrode can contact the human hand, thereby forming a lead circuit to realize ECG signal collection.

[0060] The first light source 113, the second light source 114, and the photosensor 115 are all mounted on the massage head housing 111. Illustratively, the first light source 113, the second light source 114, and the photosensor 115 can be positioned between the positive electrode 112 and the negative electrode 116, and can be positioned on the same side of the photosensor 115. The relative positions of the first light source 113, the second light source 114, the photosensor 115, and the positive electrode 112 and the negative electrode 116 are merely illustrative, and this embodiment is not limited thereto. Furthermore, the number of light sources can be designed as desired and is not limited to two; for example, it can be one, three, or more.

[0061] The first light source 113, the second light source 114 and the photosensor 115 are spaced apart in pairs. The first light source 113 is farther from the photosensor 115, while the second light source 114 is closer to the photosensor 115. The first light source 113, the second light source 114 and the photosensor 115 are all electrically connected to the signal processing module.

[0062] The first light source 113 and the second light source 114 can be, for example, light-emitting diodes (LEDs). Each light source 113 and the second light source 114 can include multiple light-emitting elements. These elements in each light source can emit light of different wavelengths, enabling each light source to be used to measure different physiological parameters (described below). The photosensor 115 can be, for example, a photodiode (PD), which converts optical signals into electrical signals. Thus, the light source and photosensor 115 can detect physiological parameters such as muscle oxygen saturation, blood oxygen saturation, heart rate, and lactate level.

[0063] like Figure 5 As shown, the first light source 113 and the photosensor 115 form a first optical signal detection channel, and the second light source 114 and the photosensor 115 form a second optical signal detection channel. In the optical signal detection channel, light is emitted from the light source and penetrates the skin. After being scattered and absorbed by human tissue, it is emitted from the skin and received by the photosensor 115. According to practical rules, in the first optical signal detection channel where the distance between the first light source 113 and the photosensor 115 is larger, the light therein penetrates the skin to a greater depth, for example, the light therein can penetrate into muscle tissue. Therefore, the first optical signal detection channel can be used to detect muscle oxygen saturation. In the second optical signal detection channel where the distance between the second light source 114 and the photosensor 115 is smaller, the light therein penetrates the skin to a shallower depth, for example, the light therein can penetrate into skin tissue (for example, reaching the dermis). Therefore, the second optical signal detection channel can be used to detect blood oxygen saturation.

[0064] The positive electrode 112, negative electrode 116, wet electrode, first light source 113, second light source 114, and photosensor 115 all constitute a detection module, which is used to measure corresponding physiological parameters (described further below). The massage head 11 of the present embodiment includes the positive electrode 112, negative electrode 116 (and, if desired, a wet electrode), first light source 113, second light source 114, and photosensor 115, respectively, for illustrative purposes only. In practice, a massage head may include only a few of the aforementioned detection modules, for example, only the positive electrode 112 and negative electrode 116, only the positive electrode 112, negative electrode 116, and / or wet electrode, or only the light source and photosensor 115.

[0065] The signal processing module is electrically connected to each of the aforementioned detection modules and is used to preprocess the physiological signals detected by the detection modules (e.g., filtering, noise reduction, amplification, etc.) to generate a preprocessed signal containing information about physiological parameters. The signal processing module is electrically connected to the second interface 117 and transmits this preprocessed signal to the algorithm module in the host computer 12 via the second interface 117 and the first interface 127. The algorithm module operates on this preprocessed signal to assess the physiological condition of the human body (described further below).

[0066] In this embodiment, the massage head 11 transmits signals (including pre-processed signals) to the main unit 12 via an electrical connection interface. This design is simple and low-cost. In other embodiments, the electrical connection interface can be eliminated, and the massage head and main unit can transmit signals via short-range wireless communication. For example, the massage head can include a first Bluetooth module embedded in the massage head housing, and the main unit can include a second Bluetooth module embedded in the main unit housing. Signals between the massage head and main unit can be transmitted via the first and second Bluetooth modules.

[0067] In this embodiment, the massage head 11 may also include a power module housed within the massage head housing 111. This power module is used to supply power to the aforementioned detection modules, signal processing module, positive electrode 112, and negative electrode 116 (which may also include a wet electrode). This allows the massage head 11 to be self-powered, eliminating the need for power from the main unit 12. This conserves power and improves the main unit's battery life. In other embodiments, the massage head may not have a built-in power module, but instead be powered by the main unit 12.

[0068] Figure 6 and Figure 7 Indicates that another massage head 13 can be installed on the host 12. Figure 6 and Figure 7 As shown, unlike the massage head 11 described above, the massage head 13 is generally Y-shaped. The massage head housing 131 of the massage head 13 may include first massage columns 131a, second massage columns 131c, and a connecting portion 131b. The first and second massage columns 131a, 131c may be substantially cylindrical, and the connecting portion 131b may be substantially T-shaped. The first and second massage columns 131a, 131c are connected to the same side of the connecting portion 131b, such that the horizontal portion of the T-shaped connecting portion 131b connects approximately at right angles to the first and second massage columns 131a, 131c, and the vertical portion of the T-shaped connecting portion 131b is approximately parallel to the first and second massage columns 131a, 131c. The end of the connecting portion 131b, distal from the first and second massage columns 131a, 131c, is removably connected to the drive unit 126 of the main unit 12.

[0069] Alternatively, if the driving device 126 is completely located in the main body housing 123, the connecting portion 131b can extend into the main body housing 123 and be detachably connected to the driving device 126. In this case, the connecting portion 131b is also detachably connected to the main body housing 123.

[0070] like Figure 7 As shown, the positive electrode 132 in the massage head 13 can be located on the surface of the end of the first massage column 131a away from the connecting portion 131b, and the positive electrode 132 can be located on the cylindrical bottom surface of the first massage column 131a. The negative electrode 134 in the massage head 13 can be located on the surface of the end of the second massage column 131c away from the connecting portion 131b, and the negative electrode 134 can be located on the cylindrical bottom surface of the second massage column 131c.

[0071] like Figure 7 As shown, the first massage column 131a may have a connecting structure 133 at one end away from the connecting portion 131b, and the second massage column 131c may have a connecting structure 135 at one end away from the connecting portion 131b. Connecting structures 133 and 135 are used to connect wet electrodes. For example, connecting structures 133 and 135 may be receptacles that can be plugged into the wet electrodes. Through connecting structures 133 and 135, the massage head 13 can be detachably connected to the first and second wet electrodes. The massage head 13 may also have a wet electrode interface that is electrically connected to the signal processing module. Both the first and second wet electrodes connected to the massage head 13 can be electrically connected to the signal processing module via the wet electrode interface.

[0072] The massage head 13 can collect bioelectric signals (such as myoelectric signals, electrocardiographic signals, and human body impedance) of the human body through the positive electrode 132 and the negative electrode 134, and / or the first wet electrode and the second wet electrode.

[0073] Illustratively, the massage head 13 may not have a light source and a light-sensitive sensor.

[0074] The above describes the structure of the massage device 10 in detail. Now, how the massage device 10 works will be described.

[0075] The working modes of the massage device 10 may include a detection mode and a massage mode.

[0076] The detection mode is used to detect physiological parameters of the human body. The detection mode may include a muscle fatigue detection mode (for detecting muscle fatigue), a body impedance detection mode (for detecting body impedance), and an electrocardiogram (ECG) detection mode (for detecting ECG signals).

[0077] The massage device 10 can also establish a communication connection with an external device (such as a mobile phone or tablet computer) that has a built-in health management application (APP). This communication connection can be a short-range wireless communication connection (such as a Bluetooth connection). The massage device 10 can send the detection results to the external device. The APP in the external device generates a massage plan based on the detection results and sends the massage plan to the massage device 10. The massage device 10 then performs the massage according to the massage plan.

[0078] Figure 8 Taking the massage device 10 as a fascia gun as an example, a flowchart of the massage device 10 detecting muscle fatigue and intelligently performing massage according to muscle fatigue is schematically illustrated.

[0079] Combine Figure 8 and Figure 1 As shown, the massage device 10 can detect muscle fatigue by detecting at least one of the body's electromyographic signals, body impedance signals, and muscle oxygen saturation. The user connects the massage head 11 to the main unit 12 and establishes a communication connection between the fascia massage gun and the mobile phone app. The user then positions the positive electrode 112 and negative electrode 116 of the massage head 11 in contact with a human body part (with the first light source 113, second light source 114, and photosensor 115 also aligned with the body part) to prepare for muscle fatigue detection. At this point, the indicator light 121 of the main unit 12 illuminates in a pre-set manner to indicate whether the positive electrode 112 and negative electrode 116 are in good contact with the body part. If the indicator light 121 indicates that the positive electrode 112 and negative electrode 116 are in good contact with the body part, the user can press a button (e.g., button 124 or button 125) to initiate the test. The positive electrode 112 and negative electrode 116 detect the electromyographic signals and / or body impedance signals, and the first light source 113 and photosensor 115 detect muscle oxygen saturation. The detection of myoelectric signals / body impedance signals and the detection of muscle oxygen saturation can be performed simultaneously, or only one of them needs to be performed.

[0080] like Figure 8 As shown, after a certain period of time, massage head 11 can complete the detection of electromyographic signals, human body impedance signals, and / or muscle oxygen saturation. The detection signals of massage head 11 can be pre-processed by the signal processing module to generate raw detection data. Massage head 11 can then send the raw detection data to the algorithm module in host computer 12. The algorithm module can process and calculate the raw detection data according to the built-in algorithm to assess muscle fatigue, that is, detect muscle fatigue.

[0081] Indicatively, the algorithm module can perform time domain analysis, frequency domain analysis, or time-frequency domain analysis on the collected original detection data. Among them, the root mean square amplitude and amplitude integral value of the signal are analyzed through time domain analysis to reflect the change of the signal amplitude and time, and find the correlation between muscle fatigue and the root mean square amplitude and amplitude integral value. By performing spectral analysis on the signal, the average frequency, median frequency, and spectral power of the signal in different frequency bands are obtained, and the change pattern and trend of muscle fatigue and indicators such as average frequency, median frequency, and spectral power are found. By further analyzing the signal in the time-frequency domain, the instantaneous average frequency and instantaneous median frequency of the signal can be calculated. The two indicators of instantaneous average frequency and instantaneous median frequency can more accurately characterize muscle fatigue.

[0082] In general, the built-in algorithm can establish a muscle fatigue model and classify and identify muscle fatigue using machine learning methods based on the characteristics of different muscle areas. For example, a muscle fatigue neural network model can be constructed to identify muscle fatigue. Muscle fatigue features can be extracted using time-frequency analysis, combined with K-nearest neighbor, support vector machine, linear discriminant, and Bayesian classifiers. Sample entropy can be used to extract muscle fatigue features, and combined with support vector machine methods to classify exercise fatigue.

[0083] like Figure 8 As shown, after the massage device 10 detects muscle fatigue, it can transmit the muscle fatigue data to the mobile phone app. The app can then evaluate and determine a massage plan based on the muscle fatigue data. The massage plan may include the type of massage head to use, the intensity to use, and the duration of the massage.

[0084] The app can send massage instructions to the massage device 10, causing it to execute the massage plan. The app and / or the massage device 10 can prompt the user to install the corresponding massage head. The user follows this prompt and connects the corresponding massage head to the host 12. The massage device 10 can detect whether the massage head is installed. If not, the app and / or the massage device 10 will continue to prompt the user to install the corresponding massage head. If installed, the app and / or the massage device 10 will prompt the user to start the massage plan. The user can press a button (e.g., button 124 or button 125) to start the massage.

[0085] After the massage plan is completed (i.e., the massage is complete), the app can notify the user that the massage is complete. At this point, the user can manually control the massage device 10 to perform another muscle fatigue test, or the app can issue a muscle fatigue test command to the massage device 10, causing it to automatically perform a muscle fatigue test. This allows the massage device 10 to obtain muscle fatigue data after the massage. The app and / or the massage device 10 can compare muscle fatigue before and after the massage to evaluate the massage's effectiveness. The evaluation results can be displayed to the user, allowing them to understand the muscle condition before and after the massage.

[0086] Figure 9 Taking the massage device 10 as a fascia gun as an example, a flowchart of how the massage device 10 detects human fatigue (or human fatigue level) and intelligently massages the human body according to the human fatigue level is schematically illustrated. The massage head in the massage device 10 is schematically represented as a massage head 11.

[0087] Combine Figure 9 and Figure 1 As shown, human fatigue detection can be completed jointly by the APP and the massage device 10. The user can connect the massage head 11 to the host 12, and establish a communication connection between the fascia gun and the mobile phone APP. The APP has a human fatigue detection function, and the user can select human fatigue detection in the user interface of the APP to enter the human fatigue detection process. The APP will generate a physiological parameter detection plan for key parts of the human body, which may include, for example, shoulders, neck, back, waist, chest, abdomen, legs, etc. The APP can send the detection plan to the massage device 10. The massage device 10 executes the detection plan, so that the massage head 11 detects the physiological parameters of the key parts, for example, it can detect the electromyographic signals, human body impedance, electrocardiogram signals, muscle oxygen saturation, blood oxygen saturation, lactate value, etc. of each key part.

[0088] After a certain period of time, the massage head 11 can complete the physiological parameter detection of all key areas. The detection signals from the massage head 11 can be preprocessed by the signal processing module to generate raw detection data. The massage head 11 can then send this raw detection data to the algorithm module in the host computer 12. The algorithm module can analyze and calculate the raw detection data based on its built-in algorithm. In addition, the algorithm module can also obtain more reliable physiological parameter detection data, such as respiratory rate, sleep, heart rate, etc., from other peripheral devices (such as wearable devices such as smart bracelets and smart watches, or mobile phones and tablets) through an app. The algorithm module can then analyze and calculate this detection data together.

[0089] The analysis results of the massage head 11 can be sent to the APP. The APP can evaluate the fatigue level of the human body and the fatigue distribution of key parts of the human body based on the analysis results. Among them, the fatigue distribution can present the fatigue level of each key part of the human body in a manner similar to the hotspot distribution. The APP can also generate a massage plan based on the evaluation results. The massage plan is suitable for the current physiological state of the human body. Therefore, it is an intelligent, flexible and customized massage plan, rather than a conventional solidified massage plan. In addition, the APP can also provide an explanation and / or operating instructions of the massage plan so that the user can better use the massage device 10 for massage. The APP can send the massage plan and the explanation and / or operating instructions to the massage device 10 through massage instructions.

[0090] The user can install the corresponding massage head according to the operating instructions. After the massage device 10 confirms that the massage head is correctly installed, it can initiate the massage in response to a user trigger (e.g., by pressing a button) or automatically initiate the massage, so that the massage head performs the massage according to the massage plan. After the massage is completed, the app and / or massage device 10 can notify the user that the massage is complete.

[0091] At this point, the massage device 10 can evaluate the massage effect under the user's trigger (for example, by pressing a button) or automatically. Specifically, the massage device 10 can re-detect the electromyographic signal, body impedance, electrocardiographic signal, muscle oxygen saturation, blood oxygen saturation, lactate value, etc. of the key area, thereby obtaining the physiological parameters of the key area after the massage. The massage device 10 can send the detected physiological parameters to the app. The app can re-evaluate the body's fatigue based on these physiological parameters and can also evaluate the massage effect. The evaluation results can be displayed to the user to enable the user to understand the physiological state before and after the massage. The app can also generate and display a human fatigue report to the user.

[0092] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
