Mode for Carrying Out the Invention

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

[0020] FIG. 1 and FIG. 2 are schematic configuration 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 main body 1 including a first surface 2 and a second surface 3, and a penetrable structure for the user to wear is formed by connecting the first surface 2 and the second surface 3 to each other.

[0021] The main body 1 has a positioning structure 6. The positioning structure 6 is located on the connection line 4 between the first surface 2 and the second surface 3, and the opening of the positioning structure 6 penetrates the main body 1. Preferably, the center point of the positioning structure 6 is located on the connection line 4. During use, when the positioning structure 6 corresponds to the acromion of the user, after the user wears the adjustable upper limb wearable device 100, the sensors of the adjustable upper limb wearable device can be accurately positioned only by 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 line 4 between the first surface 2 and the second surface 3. During wearing, the edge portion 5 is attached to the user's back, shoulders and chest. Also, by having the edge portion 5 connected to the second surface 3 parallel to the user's spine, it makes it easier for medical staff to determine whether the user is wearing the adjustable upper limb wearable device 100 correctly. In addition, the edge portion 5 has an elastic fixture 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 is provided with a first sensor fixture 7. The first sensor fixture 7 is installed on the connection line 4 between the first surface 2 and the second surface 3 and is adjacent to the positioning structure 6. The first sensor 71 is removably accommodated in the first sensor fixture 7 and is used to sense the physiological signals of the middle deltoid muscle of the user. Preferably, the physiological signals sensed by the first sensor 71 may be electromyographic signals on the skin surface, but the present invention is not limited thereto, and the user can select the necessary sensors according to the needs of training or measurement.

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

[0025] In the invention of this embodiment, it is projected to the projection center where the first sensor fixture 7 is 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 fixture 7 is in the range of 3 cm to 8 cm.

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

[0027] Figure 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 has 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. When 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, it is ensured that the detection element placement of the first sensor 71 is attached at an accurate position and in an accurate direction. By accurately aligning the detection element 73 with the through hole 74 of the main body 1, when the detection element collects the physiological signal of the user, the situation where an error occurs due to inaccurate position is prevented.

[0028] The invention of this embodiment further includes a second sensor fixture 8 installed on the connection line 4 of the adjustable upper limb wearable device 100. 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 accommodated in the second sensor fixture 8. During use, the second sensor 81 corresponds to the user's upper trapezius muscle and is used to sense the physiological signal of the user's upper trapezius muscle.

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

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

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

[0032] The invention of this embodiment further includes an adjustable upper limb wearable device 100 with 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 the fourth sensor 101 is removably accommodated in the fourth sensor fixture 10. During use, the fourth sensor 101 corresponds to the user's pectoralis major muscle and is used to sense the physiological signal of the user's pectoralis major muscle.

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

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

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

[0036] The invention of other embodiments has a specific angle between the connection line between the sensors of the adjustable upper limb wearable device 100 and the connection line between the sensor and the center point of the positioning mechanism 6. Taking an example, the third sensor fixture 9 is projected to the projection center of the main body 1, and the included angle between the connection line where the second sensor fixture 9 is projected to the projection center of the main body 1 and the connection line where the third sensor fixture 9 is projected to the projection center of the main body 1 and the center point of the positioning structure 6 is set to 15 degrees.

[0037] Alternatively, referring to FIG. 5, the included angle between the connection line where the fourth sensor fixture 10 is projected to the projection center of the main body 1 and the center point of the positioning structure 6 and the connection line where the fourth sensor fixture 10 is projected to the projection center of the main body 1 and the connection line where the second sensor fixture 8 is projected to the projection center of the main body 1 is set to 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. Descriptions of related points are omitted.

[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, are provided with three sensing elements penetrating the main body 1 and positioning members corresponding to the positioning parts of the sensor fixtures, and descriptions of related points are omitted.

[0040] As shown in FIG. 6, the invention of other embodiments may be a set of two adjustable upper limb wearable devices 100. During use, the two adjustable upper limb wearable devices 100 respectively correspond to the user's both shoulders. In this embodiment, the two elastic fixtures 12 are connected to the two adjustable upper limb wearable devices 100, and the user can selectively adjust the length of the elastic fixture 12 according to the body type to fix the two adjustable upper limb wearable devices 100 on the shoulders.

[0041] As shown in FIG. 7, in the invention of another embodiment, the upper limb detection system 200 includes at least one of the aforementioned adjustable upper limb wearable devices 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, medical staff can set the numerical values of training parameters by the setting device 206. The processor 203 is used to read the training content stored in the memory 204 and display the training content on the display 205 for the user to see. The signal receiver 202 is used to receive signals 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 numerical value of the received signal is the same as the numerical value set by the medical staff using the setting device 206, and stores the comparison result in the storage 208. After the training flowchart ends, the medical staff can know the user's training performance by reading the comparison result stored in the storage 208 and adjust the parameter numerical values for the next training.

[0044] In conclusion, the adjustable upper limb wearable device according to the present invention is not only convenient to wear, but also when the user wears it, by aligning the positioning structure with the acromion, the plurality of sensor fixtures of the adjustable upper limb wearable device can be quickly positioned to ensure that the sensors are located at accurate positions. Further, when the sensor is attached to the sensor fixture, the positioning member ensures that the attachment direction of the sensor is accurate. By doing so, when the adjustable upper limb wearable device collects data from the user, it prevents the situation where the position or direction of the sensor is inaccurate and an error occurs, and provides accurate data as a material for medical staff 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 construed in a limiting sense.
