Description

Smart Wearable Devices

The present invention relates to a wearable device, in particular to a smart wearable device that is held on the upper limb of a wearer by a plurality of contact pad groups.

Population aging has become an important social issue in the world. In recent years, the problem of "sarcopenia" in the elderly has received great attention. With the increase of age, muscle size and strength gradually decline, causing the overall physiological function to show a downward trend, resulting in symptoms of weakness and sarcopenia, which in turn increases the risk of death and extends multiple complications. And because the core concept of sarcopenia is the loss of skeletal muscle, it is more obvious than the normal aging process, which in turn affects the performance of muscle function, resulting in limited mobility, and often facing obstacles in carrying out daily activities, further causing adverse effects on health.

At present, elderly people or patients with sarcopenia are allowed to undergo resistance exercise training to increase muscle mass or strength. However, general resistance exercise training usually requires going to a gym or a place with gravity training equipment for exercise training, which is not easy for elderly people who already have functional decline problems, and the number of training sessions is easily limited by the manpower or space of professional coaches. In addition, with the advent of an aging society, the number of rehabilitation patients and sub-healthy groups is increasing day by day. Frailty is a common condition among the elderly, increasing the risk of falls and causing other complications. Generally, rehabilitation training can be carried out to help restore the motor function of the limbs. The traditional one-on-one training method requires a huge number of therapists. The current domestic gap is difficult to fill in the short term. In addition, the rehabilitation process is boring and lacks the active participation of the brain's motor nerves that control the limbs, resulting in poor rehabilitation results.

In the 21st century digital and information explosion era, technological changes have rapidly changed people's lifestyles, leading to the development of new technologies such as smart medicine and smart sensors and the popularization of customized health care concepts. The field of smart wearable devices has also grown rapidly in recent years and has become one of the areas with promising medical development prospects. The medical development and application of wearable devices include the digitization of behavioral functions and health monitoring content to achieve medical preventive health care effects, and even to be applied in medical rehabilitation to improve the overall effect and efficiency of rehabilitation training, thereby improving the convenience, safety and comfort of users.

Based on this, through wearable devices and information and communication integration technology, a remote and digital service system is provided for people with sarcopenia, frailty, and the elderly, providing appropriate rehabilitation programs, while reducing the user's experience of fatigue and increasing the motivation for long-term rehabilitation training, so as to resonate with the elderly and reduce the negative impact of aging.

The relevant patent application features and technical contents of the present invention will be clearly presented in the following detailed description of the preferred embodiment with reference to the drawings.

Referring to Figures 1 and 2, the first preferred embodiment of the smart wearable device of the present invention is shown. The smart wearable device is maintained on the upper limb of a wearer with a plurality of contact pad groups 6, which include a connection unit 1, a first sensing module 2, a second sensing module 3, and an extension unit 4. Each contact pad group 6 is a group of three to be maintained on the upper limb of the wearer. The wearable device is designed to be comfortable and easy to wear, and can effectively record the value, direction and speed of multiple muscle group movements.

The connecting unit 1 includes a connecting belt 11 that can be detachably held on the upper limb of the wearer, a first positioning groove 12 disposed on the connecting belt 11, a first positioning group 13 opened on the first positioning groove 12, a second positioning groove 14 disposed on the connecting belt 11, and a second positioning group 15 opened on the second positioning groove 14.

The connecting belt 11 has a first end 111 and an opposite second end 112. A horizontal line L1 and a vertical line L2 perpendicular to the horizontal line L1 are formed from the first end 111 to the second end 112. The first positioning groove 12 is located at the first end 111, and the second positioning groove 14 is located at the second end 112. The horizontal line L1 is the length direction of the connecting belt 11, and the vertical line L2 is the width direction of the connecting belt 11. The horizontal line L1 is not located in the middle of the width direction of the connecting belt 11.

In actual implementation, the contact pad can take different forms depending on the specific application, such as being provided in the form of an active therapy device, such as a neuromuscular electrical stimulation pad (NMES) or a microthermal therapy pad, or in the form of a transcutaneous therapy pad analgesic patch, or in the form of an acupuncture patch. In applications that capture range of motion/motion tracking data, the contact pad can take the form of a precisely placed physiological sensor component, configured as a corresponding external additional component, to extract or otherwise obtain physiological information associated with the wearer's body part (such as muscle group tracking, range of motion, activity, load, etc.).

Here, the contact pad is an electromyographic patch, which is used to measure electromyographic signals. It is attached to the skin on the surface of the muscle to measure the voltage changes of the muscle during the activity. The larger the electromyographic signal, the more motor units involved in the muscle activity, and the higher the stimulation level. The electromyography (EMG) is used to infer the degree of local muscle activity. The surface electromyographic signals and six-axis inertial sensing technology are captured to effectively detect and store the activity of each muscle group of the wearer during sports training. The relevant information of the obtained signal is then stored in a host device and processed by the back-end system for data analysis and evaluation.

The connecting belt 11 further has a plurality of alignment calibration lines 113 located at the second end 112, and each alignment calibration line 113 is arranged at intervals along the vertical line L2. In addition, the connecting belt 11 further has a first coupling member 114 located at the first end 111 and a second coupling member 115 located at the second end 112. The first and second coupling members 114 and 115 are connected to each other to keep the connecting belt 11 on the upper limb of the wearer.

The plurality of alignment lines 113 are configured to be able to be adjusted at intervals on the wearer's upper limbs, so that the connection belt 11 can fit users of different body shapes, thereby achieving a universal design trend. In addition, the first and second coupling members 114 and 115 are configured to be coupled to each other to form a loop, so that the connection unit 1 can be wrapped around the wearer's upper limb in a self-retaining manner, wherein the first coupling member 114 is provided with a threading groove, and the second coupling member 115 is provided with a Velcro, and the second coupling member 115 passes through the threading groove, and the Velcro is adhered to the connection belt 11 to tighten it. In actual implementation, the first and second coupling parts 114 and 115 can be configured as a button, a magnet, an adhesive, a latch or an elastic band structure to be coupled to each other on the upper limbs of the wearer.

The first positioning groove 12 and the second positioning groove 14 are arranged on the horizontal line L1 at intervals symmetrical to the left and right, and the first positioning group 13 and the second positioning group 15 are arranged on the horizontal line L1 at intervals symmetrical to the left and right.

Furthermore, the first positioning group 13 has a first positioning hole 131, a second positioning hole 132, and a third positioning hole 133. A first setting point A1 is defined with the first positioning groove 12 as the center. The first, second, and third positioning holes 131, 132, and 133 are arranged around the first setting point A1. The first positioning hole 131 is located on the horizontal line L1. The second positioning hole 132 and the third positioning hole 133 are arranged up and down along the vertical line L2 and are located on one side of the first positioning hole 131.

The second positioning group 15 has a fourth positioning hole 151, a fifth positioning hole 152, and a sixth positioning hole 153. A second setting point A2 is defined with the second positioning groove 14 as the center. The fourth, fifth, and sixth positioning holes 151, 152, and 153 are arranged around the second setting point A2. The fourth positioning hole 151 is located on the horizontal line L1. The fifth positioning hole 152 and the sixth positioning hole 153 are arranged up and down along the vertical line L2 and are located on one side of the fourth positioning hole 151. And the first setting point A1 and the second setting point A2 are located on the horizontal line L1.

The first positioning groove 12 has a first flange 121 centered at the first setting point A1 and protruding outward along the periphery of the first positioning groove 12, and the first flange 121 is arranged close to the second positioning hole 132 and the third positioning hole 133. The second positioning groove 14 has a second flange 141 centered at the second setting point A2 and protruding outward along the periphery of the second positioning groove 14, and the second flange 141 is arranged close to the fifth positioning hole 152 and the sixth positioning hole 153.

Referring to Figures 3 and 4, the first sensing module 2 can be detachably positioned in the first positioning slot 12, and includes a first sensing group 21 positioned in the first positioning group 13. The first sensing group 21 has a first sensing point 211 connected to the first positioning hole 131, a second sensing point 212 connected to the second positioning hole 132, and a third sensing point 213 connected to the third positioning hole 133.

Here, the first sensing module 2 is used to capture the muscle activity of the biceps. The biceps, also known as the biceps brachii, is located in the front of the upper arm and is composed of two arm muscles. When we bend our elbows, the biceps contract and bulge.

The second sensing module 3 can be detachably positioned in the second positioning groove 14, and includes a second sensing group 31 located in the second positioning group 15 and held on the upper limb of the wearer through one of the contact pad groups 6. The second sensing group 31 has a fourth sensing point 311 connected to the fourth positioning hole 151, a fifth sensing point 312 connected to the fifth positioning hole 152, and a sixth sensing point 313 connected to the sixth positioning hole 153. The three contact pads of each contact pad group 6 are held on the upper limb of the wearer in a triangular form in cooperation with the fourth sensing point 311, the fifth sensing point 312, and the sixth sensing point 313.

Here, the second sensing module 3 is used to capture the muscle activity of the triceps. The triceps, also known as the triceps brachii, is located at the back of the upper arm and is composed of three groups of arm muscles. When we straighten and turn our wrists, the triceps will contract.

In this embodiment, the first flange 121 of the first positioning groove 12 and the second flange 141 of the second positioning groove 14 are designed to provide a foolproof alignment setting for guiding the wearer to place the first sensing module 2 into the first positioning groove 12 and the second sensing module 3 into the second positioning groove 14. Furthermore, it is more helpful for the contact pad set 6 to maintain a correctly aligned position on the wearer's upper limb.

The first sensing module 2 further includes a first physiological sensing circuit, and the second sensing module 3 further includes a second physiological sensing circuit. The first and second physiological sensing circuits are wirelessly connected to a multimedia interactive system 5 via Bluetooth to transmit the captured physiological sensing data and muscle activity to the outside.

In addition, the first and second sensing modules 2 and 3 respectively include a rigid outer shell for providing structural retention, and an opening and closing member for controlling the movement of the first and second sensing modules 2 and 3. The rigid outer shell provides structural support and protective shielding for other functional devices contained therein, such as physiological sensing circuits, sensor circuits, power supply units, wireless transceivers, etc. Furthermore, a bag for accommodating the first and second sensing modules 2 and 3 can be provided on the first positioning groove 12 and the second positioning groove 14, so as to support the first and second sensing modules 2 and 3 in the first and second positioning grooves 12 and 14 through the bag. In actual implementation, Velcro can be used to fix the first and second sensing modules 2 and 3, but it is not limited thereto.

In the embodiment where accurate physiological information needs to be collected, the first and second sensing modules 2 and 3 can be equipped with a variety of physiological sensor devices to meet the needs. For example, accelerometers, gyroscopes, motion sensors, proximity sensors, optical sensors, magnetometers, pressure sensors, moisture sensors, position sensors, position tracking sensors and other functions. The sensor can be selected from optical sensors, magnetic sensors, inductive sensors, capacitive sensors, electromagnetic sensors, resistive sensors, magnetoresistive sensors, infrared sensors, inclinometer sensors, piezoelectric materials or piezoelectric-based sensors, blood oxygen sensors, heart rate sensors, laser-based or ultrasound-based sensors, and electromyography-type sensors. In some embodiments, the physiological sensor can be configured to measure or sense position and orientation, acceleration, velocity, vibration, or shock along one or more axes.

In actual implementation, the obtained muscle group data is stored in the host device, which may be an intelligent health promotion service system (IHPSS), which is a multimedia interactive system designed for muscle rehabilitation 5. In some embodiments, the target muscle groups of the system may include the femoral deltoid, biceps, and triceps. To fully recover the upper limbs, the wing flap, elbow flexion, elbow extension, and other movements may be performed. By training the muscle groups, the upper limb muscle endurance can be effectively improved.

In order to generate dynamic audio-visual content integrated into interactive games based on capturing the user's motion data and other physiological information (e.g., rehabilitation movements), multimedia content is presented in the form of map-type stage/progression challenges, aiming to guide users through interactive adventure virtual games, thereby reducing the fatigue of users' training experience and stimulating the motivation for self-training.

In the implementation example, the operation of the smart health promotion service system can be divided into establishing the user's basic data, setting customized parameters, experiencing gamified rehabilitation, user feedback, and intelligent evaluation and recording. On the one hand, it can promote the integration of professional rehabilitation treatment, provide remote and digital services to the elderly with frailty during the golden treatment period or health promotion period, and accurately provide the most optimized rehabilitation plan to achieve the three service goals of "customization, gamification, and intelligence". On the other hand, it provides nostalgic retro game scene design to reduce the user's experience fatigue, resonate with the elderly, and increase rehabilitation motivation.

In addition, the condition of each muscle group of the user is detected during training, and gait analysis is used to accurately divide the gait cycle technology to assess the degree of weakness of the rehabilitator. Then, according to the needs of the rehabilitator, it promotes the generation or automatic establishment of customized game rehabilitation therapy, thereby building a high-quality clinical evaluation system. Furthermore, through deep learning and data analysis, the system assists professionals in formulating accurate rehabilitation plans for rehabilitators, and at the same time transmits the training status to their family members, allowing rehabilitators to receive rehabilitation treatment without leaving home.

Interactive physical rehabilitation content can be designed based on common upper limb rehabilitation training movements in clinical practice, such as flapping wings, elbow bending, and elbow extension. Through the virtual coaching style presented in the game, rehabilitation training can help guide the rehabilitator to complete the rehabilitation training course, which helps to motivate the patient to continue rehabilitation.

In the embodiment, the long and short-term memory (LSTM) algorithm of artificial intelligence deep learning and reinforcement learning (RL) can be used to evaluate the progress of the muscle endurance of the rehabilitator. The collected data is forwarded to the electronic health system of the service system for analysis and provided to relevant professionals for evaluation and rehabilitation treatment reference, so as to implement the prescription of customized rehabilitation treatment courses through the real-time medical sharing system.

It is also possible to create appropriate rehabilitation treatment courses based on the rehabilitation needs of the rehabilitated person, thereby forming an interactive platform for the medical sharing system, where the family of the rehabilitated person can understand the patient's daily rehabilitation situation, and doctors can also use professional reports here to continuously interact with patients and their families to further increase rehabilitation motivation and rehabilitation effects.

5, 6, and 7, the extension unit 4 includes an extension belt 41 detachably connected to the connecting belt 11, a first extension block 42 at one end of the extension belt 41, a second extension block 43 at the other end of the extension belt 41, a first buckle set 44 disposed on the first extension block 42, and a second buckle set 45 disposed on the second extension block 43. When the connecting belt 11 is connected to the extension belt 41, the extension belt 41 is located on the vertical line L2, the first buckle set 44 is connected to one of the contact pad sets 6 to keep the first extension block 42 on the upper limb of the wearer, and the second buckle set 45 is connected to the first sensing set 21 located in the first positioning groove 12. The extension belt 41 is connected to the first sensing module 2 located on the connecting belt 11 to capture the muscle activity of the deltoid muscle. Furthermore, a circuit connected to the signal of the first sensing module 2 is embedded in the extension belt 41 to transmit the electromyographic signal. And the first extension block 42 is positioned from the acromion to the upper edge of the extension belt 41 about 2 toe widths. In addition, the connecting belt 11 and the extension belt 41 are made of elastic materials, so the wearing position can be finely adjusted up and down and left and right according to the user's body shape.

The first extension block 42 is used to capture the muscle activity of the deltoid muscle. The deltoid muscle, commonly known as the "big head muscle", surrounds the shoulder blade, clavicle and humerus connected to the shoulder. Most movements of the shoulder and upper arm are inseparable from the deltoid muscle. It strengthens the shoulder and is responsible for pulling the arm forward, sideways and backward. It is a very important muscle in the body, allowing the arm to move in multiple directions.

The first extension block 42, the first setting point A1 of the first positioning groove 12, and the second setting point A2 of the second positioning groove 14 form an isosceles triangle. The distance from the first setting point A1 to the third setting point A3 is equal to the distance from the first setting point A1 to the second setting point A2, and the angles θ1 and θ2 are 45 degrees. When the length of the connecting belt 11 changes to the maximum value, the angle θ2 is 30 degrees. Therefore, the length of the connecting belt 11 makes the angle θ2 between 30 and 45 degrees, and the angle θ is 90 degrees.

Among them, the supporting members such as the connecting belt 11 and the extension belt 41 can be made of a flexible elastic fabric material, or a breathable material with high compressibility and anti-slip properties. Or use a synthetic fiber fabric with suitable surface treatment, such as antibacterial fabric, silver fiber fabric. The surface treatment may include water-repellent coating treatment, surface friction modification, antibacterial surface treatment and deodorant surface treatment. Use a flexible and anti-slip property to limit the movement of the connecting belt 11 and the extension belt 41 on the wearer's upper limb through friction and compression, thereby minimizing unwelcome friction, device misalignment or misalignment and other troubles.

Furthermore, a third setting point A3 is defined with the first extension block 42 as the center, and a fourth setting point A4 is defined with the second extension block 43 as the center. The first buckle assembly 44 has a first buckle 441, a second buckle 442, and a third buckle 443. The first, second, and third buckle 441, 442, and 443 are arranged around the third setting point A3. The second buckle assembly 45 has a fourth buckle 451, a fifth buckle 452, and a sixth buckle 453. The fourth, fifth, and sixth buckle 451, 452, and 453 are arranged around the fourth setting point A4. The fourth, fifth, and sixth buckle 451, 452, and 453 can be configured as magnetic suction parts to facilitate the disassembly from the first sensing assembly 21.

Furthermore, the fourth fastener 451 is connected to the first sensing point 211, the fifth fastener 452 is connected to the second sensing point 212, and the sixth fastener 453 is connected to the third sensing point 213.

Referring to FIGS. 8 and 9 , the second preferred embodiment of the smart wearable device of the present invention is substantially the same as the first preferred embodiment, and the similarities are not repeated here. The difference is that when the connecting belt 11 is connected to the extension belt 41, the extension belt 41 is located on the vertical line L2, and the first, second, and third fasteners 441, 442, and 443 are rotated 30 to 50 degrees clockwise relative to the fourth, fifth, and sixth fasteners 451, 452, and 453 with the third setting point A3 as the axis. The fourth, fifth and sixth positioning holes 151, 152 and 153 are rotated 15 to 30 degrees clockwise relative to the first, second and third positioning holes 131, 132 and 133 with the second setting point A2 as the axis. Therefore, the first positioning group 13 and the second positioning group 15 are not arranged on the horizontal line L1 at a left-right symmetrical interval.

The first setting point A1 is located on the horizontal line L1, and the second setting point A2 is located above or below the horizontal line L1, so that the angle θ in FIG. 7 is between 85 degrees and 105 degrees, so that the first positioning group 13 and the second positioning group 15 have a height difference.

In summary, the smart wearable device of the present invention, by means of the interconnection of the connection unit 1, the first sensing module 2, the second sensing module 3, and the extension unit 4, captures the muscle activity of the deltoid muscle through the first extension block 42, the first sensing module 2 captures the muscle activity of the biceps muscle, and the second sensing module 3 captures the muscle activity of the triceps muscle, thereby satisfying the detection of muscle activity in multiple parts of the upper limb. The plurality of alignment calibration lines 113 are configured to be able to be adjusted at intervals on the upper limb of the wearer, thereby achieving a universal design trend. Furthermore, the first and second flanges 12 The configuration of 1 and 141 provides a foolproof configuration for guiding the wearer to place the first and second sensing modules 2 and 3 in an aligned manner. Furthermore, the first and second physiological sensing circuits are used to transmit the captured physiological sensing data and muscle activity to the outside, and the collected data is analyzed to achieve the effect of integrating the wearable device with information and communication, providing a remote and digital service system for people with sarcopenia, frailty, and the elderly, accurately providing the most optimized rehabilitation plan, and at the same time reducing the user's experience of fatigue and increasing the motivation for long-term rehabilitation training, so the purpose of the present invention can be achieved.

However, the above are only two preferred embodiments of the present invention, and should not be used to limit the scope of implementation of the present invention. In other words, all simple equivalent changes and modifications made according to the scope of the patent application and the content of the invention description are still within the scope of the present invention patent.
