[0084] The spirit of the present application will be apparent to those of ordinary skill in the art after understanding the preferred embodiment of the present application, and any modifications and changes can be made by the teachings of the present application without departing from the spirit and scope of the present application.

[0085] REFERENCE Figure 1Fig. 1 is a wearing diagram of an embodiment of the upper limb wearing device of the present application. The upper limb wearing device 100 is a wearable fabric with physiological signal measurement function. When worn on a user, the upper limb wearing device 100 can measure the user's motion posture through the sensors disposed on the upper limb wearing device 100. Then, the measured motion posture can be further compared and analyzed to determine whether the user's motion posture conforms to the standard motion, so that the user can perform rehabilitation exercise with correct motion, and the information obtained can be used by a doctor or a physiotherapist to track the rehabilitation status.

[0086] The upper limb wearing device 100 includes an elbow accessory 110, an upper arm accessory 120 extending from one end of the elbow accessory 110, an upper arm strap 130 movably connected to the upper arm accessory 120, a lower arm accessory 140 extending from the other end of the elbow accessory 110, a lower arm strap 150 movably connected to the lower arm accessory 140, and a wrist strap 160 extending from one end of the lower arm accessory 140.

[0087] When the user wears the upper limb wearing device 100, the elbow accessory 110 will be fitted on the elbow 14 of the user's upper limb 10. The upper arm accessory 120 will extend along the user's upper arm 12 and fit on the side of the user's upper arm 12, and the upper arm strap 130 will be arranged around the user's upper arm 12. The lower arm accessory 140 will extend along the user's lower arm 16 and fit on the side of the user's lower arm 16, and the lower arm strap 150 will be arranged around the user's lower arm 16. The wrist strap 160 will be arranged around the user's wrist 18.

[0088] When the user correctly wears the upper limb wearing device 100, the sensors disposed on the upper limb wearing device 100 should be positioned at predetermined positions, such as specific muscle groups or joints, to ensure the reliability of the upper limb wearing device 100. Therefore, the following embodiments and drawings will explain how to make the upper limb wearing device 100 suitable for different users of different body types to improve the accuracy of measurement.

[0089] Referring to Figure 2 and Figure 3 respectively show the front view and the back view of an embodiment of the upper limb wearing device of the present application, wherein Figure 2 the front view of Fig. 1 is the side facing outward when worn, Figure 3 the back view of Fig. 2 is the side contacting the user when worn. The upper limb wearing device 100 includes an elbow accessory 110, an upper arm accessory 120, an upper arm strap 130, a lower arm accessory 140, a lower arm strap 150, and a wrist strap 160. The upper arm accessory 120 and the lower arm accessory 140 extend from the two ends of the elbow accessory 110, respectively, and the wrist strap 160 extends transversely from the lower arm accessory 140.

[0090] In some embodiments, the elbow assembly 110, the upper arm assembly 120, the lower arm assembly 140, and the wrist cuff 160 comprise a continuous fabric structure, while the upper arm cuff 130 and the lower arm cuff 150 are movably connected to the upper arm assembly 120 and the lower arm assembly 140. The upper arm cuff 130, the lower arm cuff 150, and the wrist cuff 160 can be designed to snugly wrap around the user's upper limb by means of buckles, Velcro, or the like.

[0091] The upper limb wearable device 100 further comprises an upper arm electromyography sensing module 200 and a lower arm electromyography sensing module 250, which measure the degree of muscle contraction / elongation, i.e. muscle force, of the upper arm and the lower arm. The upper limb wearable device 100 further comprises a first control module 410 and a second control module 420, which comprise an upper arm inertial sensor and a lower arm inertial sensor, respectively, to measure the angular motion, i.e. joint angle, of the upper arm and the lower arm. By integrating the information measured by the upper arm electromyography sensing module 200, the lower arm electromyography sensing module 250, the upper arm inertial sensor, and the lower arm inertial sensor, it is possible to analyze whether the user's motion posture conforms to the correct rehabilitation posture.

[0092] The upper arm electromyography sensing module 200 comprises a first differential electrode assembly 210, a second differential electrode assembly 220, and a first reference electrode assembly 230 disposed on the upper arm cuff 130, wherein the positions of the second differential electrode assembly 220 and the first reference electrode assembly 230 are adjusted relative to the first differential electrode assembly 210. The lower arm electromyography sensing module 250 comprises a third differential electrode assembly 260 and a fourth differential electrode assembly 270 disposed on the lower arm cuff 150, and a second reference electrode 280 disposed on the wrist cuff 160, wherein the position of the fourth differential electrode assembly 270 is adjusted relative to the third differential electrode assembly 260.

[0093] By adjusting the relative positions of the second differential electrode assembly 220 and the fourth differential electrode assembly 270, when the upper limb wearable device 100 is worn on the user's upper limb, the first differential electrode assembly 210 and the second differential electrode assembly 220 can be located on a pair of upper arm antagonistic muscles, such as the biceps and the triceps, respectively, while the third differential electrode assembly 260 and the fourth differential electrode assembly 270 can be located on a pair of lower arm antagonistic muscles, such as the wrist flexor and the wrist extensor, respectively.

[0094] For example, the first differential electrode assembly 210 includes a ring-shaped carrier 212 and two differential electrodes 214, 216 disposed on the ring-shaped carrier 212, wherein the ring-shaped carrier 212 is fixed on the upper arm strap 130 and the ring-shaped carrier 212 further passes through the upper arm fitting 120. The second differential electrode assembly 220 includes a ring-shaped carrier 222 and two differential electrodes 224, 226 disposed on the ring-shaped carrier 222, wherein the ring-shaped carrier 222 passes through the upper arm strap 130 such that the positions of the two differential electrodes 224, 226 are adjusted relative to the upper arm strap 130.

[0095] In an embodiment, the differential electrodes 214, 216, 224, 226 are long strip-shaped, and the differential electrodes 214, 216 are parallelly disposed, and the differential electrodes 224, 226 are parallelly disposed. The axial directions of the differential electrodes 214, 216, 224, 226 are substantially perpendicular to the axial direction of the upper arm fitting 120, so that the orientations of the differential electrodes 214, 216, 224, 226 are also substantially perpendicular to the muscle orientation of the upper arm, facilitating sensing of the electromyography signals.

[0096] Similarly, the third differential electrode assembly 260 includes a ring-shaped carrier 262 and two differential electrodes 264, 266 disposed on the ring-shaped carrier 262, wherein the ring-shaped carrier 262 is fixed on the lower arm strap 150 and the ring-shaped carrier 262 further passes through the lower arm fitting 140. The fourth differential electrode assembly 270 includes a ring-shaped carrier 272 and two differential electrodes 274, 276 disposed on the ring-shaped carrier 272, wherein the ring-shaped carrier 272 passes through the lower arm strap 150 such that the positions of the two differential electrodes 274, 276 are adjusted relative to the lower arm strap 150.

[0097] In an embodiment, the differential electrodes 264, 266, 274, 276 are long strip-shaped, and the differential electrodes 264, 266 are parallelly disposed, and the differential electrodes 274, 276 are parallelly disposed. The axial directions of the differential electrodes 264, 266, 274, 276 are substantially perpendicular to the axial direction of the lower arm fitting 140, so that the orientations of the differential electrodes 264, 266, 274, 276 are also substantially perpendicular to the muscle orientation of the lower arm, facilitating sensing of the electromyography signals.

[0098] The first reference electrode assembly 230 includes a ring-shaped carrier 232 and a first reference electrode 234 disposed on the ring-shaped carrier 232, wherein the ring-shaped carrier 232 passes through the upper arm strap 130 such that the position of the first reference electrode 234 is adjusted relative to the upper arm strap 130, for example, disposed at a position corresponding to a less active muscle of the upper arm, such as the lateral side of the upper arm.

[0099] Since the second reference electrode 280 of the lower arm myoelectric sensing module 250 is disposed on the wrist strap 160, the size difference of the human wrist is negligible compared to other parts of the torso. Therefore, the position of the second reference electrode 280 in the present embodiment is fixed on the wrist strap 160, so that it can be attached to the inner surface or the outer surface of the user's wrist.

[0100] In one embodiment, the first control module 410 including the upper arm inertial sensor is disposed on the first reference electrode assembly 230, and the first control module 410 is disposed on the ring-shaped carrier 232 and overlaps the first reference electrode 234. The second control module 420 including the lower arm inertial sensor is disposed on the wrist strap 160, and can be laterally spaced apart from the second reference electrode 280, so that the second reference electrode 280 and the second control module 420 are respectively arranged at positions corresponding to the inner surface and the outer surface of the wrist. However, in other embodiments, the second control module 420 can also be arranged to overlap the second reference electrode 280.

[0101] However, even though the positions of the upper arm myoelectric sensing module 200, the first reference electrode assembly 230, and the lower arm myoelectric sensing module 250 of the upper limb wearing device 100 are designed to be adjustable, it is still a big challenge for the general public without professional training to find the correct muscle group or the correct placement position. Therefore, the upper limb wearing device 100 of the present embodiment is further configured with a positioning assistance mechanism to assist the user to correctly wear the upper limb wearing device 100.

[0102] For example, referring to Figure 2 The upper arm accessory 120 includes a first adhesive block 301 and a first positioning mark M1 arranged on the first adhesive block 301 in a first direction. The first differential electrode assembly 210 fixed to the upper arm strap 130 includes a second adhesive block 302. The first differential electrode assembly 210 determines the adhesive position of the second adhesive block 302 relative to the first adhesive block 301 according to the first positioning mark M1, thereby adjusting the distance between the upper arm strap 130 and the elbow accessory 110.

[0103] The upper arm strap 130 includes a third adhesive block 303 and a second positioning mark M2 arranged on the third adhesive block 303 in a second direction. The second differential electrode assembly 220 includes a fourth adhesive block 304. The second differential electrode assembly 220 determines the adhesive position of the fourth adhesive block 304 relative to the third adhesive block 303 according to the second positioning mark M2, thereby determining the distance between the second differential electrode assembly 220 and the first differential electrode assembly 210.

[0104] The first reference electrode assembly 230 includes a fifth bonding block 305. The first reference electrode assembly 230 determines the bonding position of the fifth bonding block 305 relative to the third bonding block 303 according to the second positioning mark M2, thereby determining the distance between the first reference electrode assembly 230 and the first differential electrode assembly 210.

[0105] The lower arm accessory 140 includes a sixth bonding block 306 and a third positioning mark M3 disposed on the sixth bonding block 306 and arranged along a third direction. The third differential electrode assembly 260, fixed to the lower arm strap 150, includes a seventh bonding block 307. The lower arm strap 150 determines the bonding position of the seventh bonding block 307 relative to the sixth bonding block 306 according to the third positioning mark M3, thereby determining the distance between the lower arm strap 150 and the elbow accessory 110.

[0106] The lower arm strap 150 includes an eighth bonding block 308 and a fourth positioning mark M4 disposed on the eighth bonding block 308 and arranged along the fourth direction. The fourth differential electrode assembly 270 includes a ninth bonding block 309. The fourth differential electrode assembly 270 determines the bonding position of the ninth bonding block 309 relative to the eighth bonding block 308 according to the fourth positioning mark M4, thereby determining the distance between the fourth differential electrode assembly 270 and the third differential electrode assembly 260.

[0107] Reference Figure 4 and Figure 5 The diagrams illustrate different settings of an embodiment of the upper limb wearable device of the present invention. The first positioning mark M1 includes multiple positioning marks arranged along a first direction, such as positioning marks M1a, M1b, M1c, M1d, M1e, M1f, M1g, and M1h. These positioning marks M1a, M1b, M1c, M1d, M1e, M1f, M1g, and M1h can be designed to have different colors or be distinguished by adding scale numbers next to them, so as to facilitate the user in determining the bonding position of the second adhesive block 302 relative to the first adhesive block 301.

[0108] The second positioning mark M2 includes multiple positioning marks arranged along the second direction, such as positioning marks M2a, M2b, M2c, M2d, M2e, and M2f. These positioning marks M2a, M2b, M2c, M2d, M2e, and M2f can be designed to have different colors or be distinguished by adding scale numbers next to them, so as to help the user determine the bonding position of the fourth bonding block 304 and the fifth bonding block 305 relative to the third bonding block 303.

[0109] For example, Figure 4The setting state of the upper limb wearing device 100 can correspond to an adult male, whose upper limbs are relatively developed. Therefore, the bonding position of the second bonding block 302 on the first bonding block 301 is approximately aligned with the positioning mark Mlh, the bonding position of the fourth bonding block 304 on the third bonding block 303 is approximately aligned with the positioning mark M2f, and the bonding position of the fifth bonding block 305 on the third bonding block 303 is approximately aligned with the positioning mark M2b, so as to match the longer and thicker upper limbs of the adult male.

[0110] Conversely, Figure 5 The setting state of the upper limb wearing device 100 can correspond to a young child, whose upper limbs are relatively weak. Therefore, the bonding position of the second bonding block 302 on the first bonding block 301 is approximately aligned with the positioning mark Mla, the bonding position of the fourth bonding block 304 on the third bonding block 303 is approximately aligned with the positioning mark M2d, and the bonding position of the fifth bonding block 305 on the third bonding block 303 is approximately aligned with the positioning mark M2a, so as to match the shorter and thinner upper limbs of the young child.

[0111] Figure 2 The positioning manner of the lower arm strap 150 in the upper limb wearing device 100 and the fourth differential electrode assembly 270 is similar to that discussed in the upper limb wearing device 100 Figure 4 The positioning manner of the lower arm strap 150 in the upper limb wearing device 100 and the fourth differential electrode assembly 270 is similar to that discussed in the upper limb wearing device 100 Figure 5 The positioning manner of the lower arm strap 150 in the upper limb wearing device 100 and the fourth differential electrode assembly 270 is similar to that discussed in the upper limb wearing device 100

[0112] In summary, when the user first wears the upper limb wearing device 100, the bonding positions of the bonding blocks can be adjusted with the help of a professional, such as a physiotherapist, so as to configure the upper arm myoelectric sensing module, the first reference electrode assembly, and the lower arm myoelectric sensing module at the correct positions suitable for the user. The user can record the corresponding positioning marks of the first to fourth positioning marks in this state, and then can wear the upper limb wearing device 100 by himself according to the recorded positioning marks, which is beneficial to the achievement of the goal of home rehabilitation.

[0113] Referring to Figure 6A and Figure 6B are schematic diagrams of an embodiment of an elbow accessory in the upper limb wearing device 100 in different adjustment states. The elbow accessory 110 comprises an elbow accommodating hole 112. As described above, because of the differences in the body types of different users, the two sides of the elbow accommodating hole 112 can be further provided with a stretchable adjustment band 114, so as to adjust the length of the elbow accommodating hole 112. In an embodiment, the stretchable adjustment band 114 can comprise a Velcro band 116 and a Velcro part 118, wherein the Velcro band 116 can be, for example, the hook surface of a Velcro, the Velcro part 118 can be, for example, the loop surface of a Velcro, and the length of the Velcro band 116 is greater than the length of the Velcro part 118. The length of the elbow accommodating hole 112 can be adjusted by changing the Velcro position between the Velcro part 118 and the Velcro band 116.

[0114] Referring to Figure 7This illustration depicts a front view of another embodiment of the upper limb wearable device of the present invention. This embodiment is similar to... Figure 2 The difference in the embodiments is that the first differential electrode assembly 210 may be further provided with a tenth bonding block 310, so that the bonding position of the tenth bonding block 310 on the third bonding block 303 is determined by the second positioning mark M2 on the upper arm strap 130, so that the relative position of the first differential electrode assembly 210 and the second differential electrode assembly 220 can be adjusted more flexibly. The third differential electrode assembly 260 may be further provided with an eleventh bonding block 311, so that the bonding position of the eleventh bonding block 311 on the eighth bonding block 308 is determined by the fourth positioning mark M4 on the lower arm strap 150, so that the relative position of the third differential electrode assembly 260 and the fourth differential electrode assembly 270 can be adjusted more flexibly.

[0115] Next, please return to Figure 3 The upper arm wearable device 100 also includes conductive fabric cables 500, such as conductive fabric cables 500a-500e, for electrically connecting the upper arm electromyography sensing module 200 to the first control module 410 (see [link]). Figure 2 ), and for electrically connecting the lower arm electromyography sensing module 250 to the second control module 420.

[0116] For example, conductive fabric cable 500a connects the first differential electrode assembly 210 and the first control module 410; conductive fabric cable 500b connects the second differential electrode assembly 220 and the first control module 410; conductive fabric cable 500c connects the third differential electrode assembly 260 and the second control module 420; conductive fabric cable 500d connects the fourth differential electrode assembly 270 and the second control module 420; and conductive fabric cable 500e connects the second reference electrode 280 and the second control module 420. The first reference electrode 234 can be directly connected to the first control module 410 through the structural arrangement in the first reference electrode assembly 230.

[0117] Reference Figure 8 This is an enlarged view of an embodiment of the conductive fabric yarn in the upper limb wearable device of the present invention. The conductive fabric yarn 500 includes conductive warp yarns 510, structural warp yarns 520, and weft yarns 530, wherein the conductive warp yarns 510 and structural warp yarns 520 are arranged in parallel, and the weft yarns 530 are interwoven with the conductive warp yarns 510 and structural warp yarns 520 to jointly constitute the conductive fabric yarn 500.

[0118] The conductive warp yarns 510 can be twisted from multiple conductive fibers, such as silver fibers, which are twisted with each other at a twist level of 75 rpm to 300 rpm so that the conductive warp yarns 510 have a required structural strength. In an embodiment, two conductive warp yarns 510 can be arranged side by side and in contact with each other to form a conductive channel CH. By arranging the two conductive warp yarns 510 in contact with each other, the impedance of the conductive channel CH can be further reduced, thereby improving the sensitivity of sensing. The number of conductive channels CH in the conductive fabric cable 500 can be one or more. In the present embodiment, two conductive warp yarns 510 form a conductive channel CH, and the conductive fabric cable 500 has a two-channel design, but the present application is not limited thereto.

[0119] In an embodiment, the weft yarns 530 can be S-shaped interwoven with the conductive warp yarns 510 and the structural warp yarns 520, and in the same conductive fabric cable 500, the S-shaped weft yarns are continuously woven transversely from one side of the conductive fabric cable 500 to the other side. That is, in the same conductive fabric cable 500, the conductive warp yarns 510 and the structural warp yarns 520 are positioned by the S-shaped weft yarns 530 shuttling.

[0120] Since the weft yarns 530 are S-shaped interwoven with the conductive warp yarns 510 and the structural warp yarns 520, the S-shaped weft yarns 530 have extensibility in the extension direction of the conductive warp yarns 510 (or the long axis direction of the conductive fabric cable 500), and the conductive fabric cable 500 also has extensibility. The conductive fabric cable 500 has good conformability, extensibility, and flexibility, and thus can maintain signal transmission stability while adjusting the positions of the upper arm myoelectric sensing module and the lower arm myoelectric sensing module.

[0121] Referring to Figure 9 which is a schematic view of the upper limb wearing device of the present application correctly worn on the upper limb of a user. For ease of illustration, only the differential electrodes 214, 216, 224, 226, 264, 266, 274, 276, the first control module 410, the second control module 420, and the conductive channels CH in the conductive fabric cable are drawn in the figure.

[0122] The differential electrodes 214, 216 and the differential electrodes 224, 226 are respectively arranged on the pair of upper arm antagonistic muscles, such as the differential electrodes 214, 216 arranged on the triceps muscle and the differential electrodes 224, 226 arranged on the biceps muscle. The first control module 410 with the upper arm inertial sensor is arranged at a position less affected by the muscle contraction, such as a position below the lower edge of the deltoid muscle and between the biceps muscle and the triceps muscle. A first reference electrode (not shown in the figure) can be arranged to overlap the first control module 410. The differential electrodes 214, 216, 224, 226 are connected to the first control module 410 through the conductive channels CH.

[0123] The differential electrodes 264, 266 and the differential electrodes 274, 276 are respectively arranged on the pair of lower arm antagonistic muscles, such as the differential electrodes 264, 266 arranged on the extensor carpi ulnaris muscle and the differential electrodes 274, 276 arranged on the extensor carpi radialis longus muscle. The second control module 420 with the lower arm inertial sensor is arranged at a position less affected by the muscle contraction, such as a position on the outer surface of the wrist. A second reference electrode (not shown in the figure) can be arranged to be laterally spaced apart from the second control module 420 by a distance or to overlap the second control module 420. The differential electrodes 264, 266, 274, 276 are connected to the second control module 420 through the conductive channels CH.

[0124] The first control module 410 and the second control module 420, in addition to containing the upper arm inertial sensor and the lower arm inertial sensor, also have a processing unit or a wireless transmission unit, etc. to analyze and record or output the signals sensed.

[0125] The upper limb wearing device provided by the present application allows the user to adjust the position of the electromyographic sensor by himself, so that the electromyographic sensor can be arranged at the correct position, which helps to improve the accuracy of motion analysis. In addition, through the positioning marks arranged on the upper limb wearing device, the user can still correctly arrange the electromyographic sensor at the correct position without the assistance of professionals, which is beneficial to home rehabilitation.

[0126] Although the present application has been disclosed with the above embodiments, it is not intended to limit the present application, and any person skilled in the art can make various modifications and improvements without departing from the spirit and scope of the present application, so the protection scope of the present application shall be subject to the scope defined by the appended claims.
