[0019] Hereinafter, the embodiments of the present invention will be described in detail. However, the present invention is not limited to these, and various modifications are possible within the scope of the description. The technical scope of the present invention also includes embodiments obtained by appropriately combining the technical means disclosed in the different embodiments.

[0020] 1 and 2 are schematic diagrams showing an adjustable upper limb wearable device according to an embodiment of the present invention. The adjustable upper limb wearable device 100 according to the present invention has a body 1 including a first surface 2 and a second surface 3, and the first surface 2 and the second surface 3 are connected to each other to form a penetrable structure for a user to wear.

[0021] The main body 1 has a positioning structure 6. The positioning structure 6 is located on the connecting line 4 of the first surface 2 and the second surface 3, and an opening of the positioning structure 6 penetrates the main body 1. Preferably, the center point of the positioning structure 6 is located on the connecting line 4. In use, the positioning structure 6 corresponds to the acromion of the user, and after the user wears the adjustable upper limb wearable device 100, the sensor of the adjustable upper limb wearable device is positioned at an accurate position by simply aligning the acromion with the positioning structure 6.

[0022] The main body 1 further has an edge portion 5. The edge portion 5 is connected to the first surface 2 and the second surface 3, and is connected to the end points of the connection lines 4 of the first surface 2 and the second surface 3. When worn, the edge portion 5 is attached to the back, shoulders, and chest of the user. In addition, the edge portion 5 connected to the second surface 3 is parallel to the user's spine, making it easier for medical personnel to determine whether the user is wearing the adjustable upper limb wearable device 100 correctly. In addition, the edge portion 5 has an elastic fastener 12 for fixing the upper limb detection device 100 to the user's body.

[0023] The adjustable upper limb wearable device 100 according to the present invention includes a first sensor fixture 7. The first sensor fixture 7 is installed on the connecting line 4 of the first surface 2 and the second surface 3, and is adjacent to the positioning structure 6. The first sensor 71 is removably housed in the first sensor fixture 7 and is used to sense the physiological signal of the middle deltoid muscle of the user. Preferably, the physiological signal sensed by the first sensor 71 may be an electromyographic signal on the skin surface, but the present invention is not limited thereto, and the user can select the required sensor according to the needs of training and measurement.

[0024] The first sensor fixture 7 has a fixing strap 72 for fixing the first sensor 71 in the first sensor fixture 7 to prevent the first sensor 71 from falling off. The fixing strap 72 and the first sensor fixture 7 may be fixed to each other by magnetic adhesion, hook-and-loop fastener, or any other fixing method, and the present invention is not limited thereto.

[0025] In this embodiment of the invention, the first sensor fixing device 7 is projected to a projection center located on the connection line 4 of the main body 1, and the shortest distance from the center point of the positioning structure 6 to the first sensor fixing device 7 is in the range of between 3 cm and 8 cm.

[0026] FIG. 3 is a schematic diagram showing a sensor according to an embodiment of the present invention. The first sensor 71 has three sensing elements 73. The three sensing elements 73 are inserted through the main body 1 via a through hole 74 in the main body 1 and contact the skin of the user. The connection lines of two of the three sensing elements of the first sensor 71 are parallel to the connection line 4, and these two sensing elements are used to collect the physiological signal of the user. The other sensing element is used to correct noise in the signal. After the user wears the adjustable upper limb wearable device 100, the connection lines of the two sensing elements for collecting the physiological signal of the user are parallel to the direction of the muscle fibers of the user. For example, the first sensor 71 has the connection lines of the two sensing elements for collecting the physiological signal of the user parallel to the muscle fiber direction of the middle deltoid muscle of the user. In the invention of this embodiment, the other sensors of the adjustable upper limb wearable device also have three sensing elements like the first sensor 71, and when worn by the user, the connection lines of the two sensing elements for collecting the physiological signal of the user are also parallel to the fiber direction of the target muscle.

[0027] 4 is a schematic diagram showing a sensor according to another embodiment of the present invention. In the invention of this embodiment, the first sensor fixture 7 further includes a positioning portion 75. The positioning portion 75 corresponds to the positioning member 76 of the first sensor 71. For example, the positioning member 76 has an arc shape, and the user attaches the first sensor 71 to the first sensor fixture 7, and at the same time aligns the arc-shaped positioning member 76 of the first sensor 71 with the positioning portion 75 of the first sensor fixture 7, and aligns the positioning portion 75 with the positioning member 76, thereby ensuring that the detection element of the first sensor 71 is attached at a correct position and in a correct direction, and the detection element 73 is accurately aligned with the through hole 74 of the main body 1, thereby preventing the detection element from being inaccurately positioned and causing errors when collecting the physiological signal of the user.

[0028] In the present embodiment, the adjustable upper limb wearable device 100 further includes a second sensor fixture 8 installed on the connecting line 4, the positioning structure 6 is located between the first sensor fixture 7 and the second sensor fixture 8, and the second sensor 81 is removably housed in the second sensor fixture 8. In use, the second sensor 81 corresponds to the upper trapezius muscle of the user, and is used to sense the physiological signal of the upper trapezius muscle of the user.

[0029] Preferably, the second sensor fixture 8 is projected to a projection center located on the connecting line 4 of the main body 1, and the shortest distance from the second sensor fixture 8 to the projection center of the main body 1 and the positioning structure 6 is in the range between 8 cm and 13 cm.

[0030] In the present embodiment, the adjustable upper limb wearable device 100 further includes a third sensor fixture 9. The third sensor fixture 9 is installed on the second surface 3 and adjacent to the edge portion 5, and a third sensor 91 is removably housed in the third sensor fixture 9. In use, the third sensor 91 corresponds to the trapezius muscle of the user's back and is used to sense a physiological signal of the trapezius muscle of the user's back.

[0031] Preferably, the shortest distance that the third sensor fixture 9 is projected to the projection center and edge portion 5 of the main body 1 is in the range between 3.5 and 6.5 cm.

[0032] In the present embodiment, the adjustable upper limb wearable device 100 further includes a fourth sensor fixture 10. The fourth sensor fixture 10 is installed on the first surface 2 and adjacent to the edge portion 5, and a fourth sensor 101 is removably housed in the fourth sensor fixture 10. In use, the fourth sensor 101 corresponds to the user's pectoralis major muscle and is used to sense a physiological signal of the user's pectoralis major muscle.

[0033] Preferably, the fourth sensor fixture 10 is projected to the projection center of the main body 1, and the shortest distance to the connecting line 4 of the first surface 2 and the second surface 3 is in the range between 10.5 to 15.5 cm.

[0034] In the present embodiment, the adjustable upper limb wearable device 100 further includes a fifth sensor fixture 11. The fifth sensor fixture 11 is installed on the first surface 2 and adjacent to the connecting line 4, and the distance projected from the center of the positioning structure 6 and the fifth sensor fixture 11 to the projection center of the body 1 is longer than the distance projected from the center of the positioning structure 6 and the first sensor fixture 7 to the projection center of the body 1. The fifth sensor 111 is removably accommodated in the fifth sensor fixture 11. In use, the fifth sensor 111 corresponds to the user's biceps and is used to sense the physiological signal of the user's biceps.

[0035] Preferably, the fifth sensor fixture 11 is projected to the projection center of the main body 1, and the distance to the center point of the positioning structure 6 is in the range between 17-22 cm.

[0036] Another embodiment of the invention has a specific angle between the connection line between the sensor of the adjustable upper limb wearable device 100 and the connection line of the center point of the sensor and the positioning mechanism 6. For example, the angle between the connection line where the third sensor fixture 9 is projected to the projection center of the body 1, where the second sensor fixture 9 is projected to the projection center of the body 1, and the connection line where the third sensor fixture 9 is projected to the projection center of the body 1 and the center point of the positioning structure 6 is 15 degrees.

[0037] Alternatively, referring to Figure 5, the angle between the connecting line projected by the fourth sensor fixture 10 to the projection center of the main body 1 and the center point of the positioning structure 6 and the connecting line projected by the fourth sensor fixture 10 to the projection center of the main body 1 and the second sensor fixture 8 to the projection center of the main body 1 is 60 degrees.

[0038] It should be noted that the second sensor fixture 8, the third sensor fixture 9, the fourth sensor fixture 10, and the fifth sensor fixture 11 are all similar to the first sensor fixture 7, and all have fixing straps for fixing the sensors, and the relevant points will not be described here.

[0039] The second sensor 81, the third sensor 91, the fourth sensor 101, and the fifth sensor 111 are all similar to the first sensor 71, and are equipped with three detecting elements that penetrate the main body 1 and positioning members that correspond to the positioning portions of the sensor fixing device, and related points will not be explained here.

[0040] In another embodiment of the invention, as shown in Fig. 6, the two adjustable upper limb wearable devices 100 may be a pair. When in use, the two adjustable upper limb wearable devices 100 correspond to the user's two shoulders respectively. In this implementation, the two elastic fasteners 12 are connected to the two adjustable upper limb wearable devices 100, and the user selectively adjusts the length of the elastic fasteners 12 according to the body type to fasten the two adjustable upper limb wearable devices 100 to the shoulders.

[0041] In another embodiment of the invention, as shown in Fig. 7, an upper limb detection system 200 includes at least one of the above-mentioned adjustable upper limb wearable device 100 and a human-computer interaction interface 201, and the adjustable upper limb wearable device 100 is connected to the human-computer interaction interface 201 in a wireless manner. For example, the wireless manner may be Bluetooth.

[0042] The human-computer interaction interface 201 includes a signal receiver 202, a processor 203, a memory 204, a display 205, a setting device 206, a comparator 207, and a storage 208. Before starting training and measurement, a medical professional can set the values ​​of training parameters by the setting device 206. The processor 203 is used to read the training contents stored in the memory 204, and displays the training contents on the display 205 for viewing by the user. The signal receiver 202 is used to receive a signal from the adjustable upper limb wearable device 100.

[0043] When the receiver 202 of the human-computer interaction interface 201 receives a signal from the adjustable upper limb wearable device 100, the comparator 207 compares whether the value of the received signal is the same as the value set by the medical staff through the setting device 206, and stores the comparison result in the storage 208. After the training flowchart is completed, the medical staff can know the user's training performance by reading the comparison result stored in the storage 208, and adjust the parameter values ​​for the next training.

[0044] In conclusion, the adjustable upper limb wearable device of the present invention is not only convenient to wear, but also aligns the positioning structure with the acromion when worn by the user, thereby quickly positioning the multiple sensor fixtures of the adjustable upper limb wearable device and ensuring that the sensors are located in accurate positions. In addition, when attaching the sensors to the sensor fixtures, the positioning members ensure that the sensor attachment directions are accurate. In this way, when the adjustable upper limb wearable device collects the user's data, the sensor positions or directions are inaccurate, which can prevent errors, and collect and provide accurate data for medical personnel to make judgments and analyses.

[0045] The present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as being limiting.
