Referring to Figures 6 and 7, before the measurement, the extension arm 312 of the forearm bracket 3 can be adjusted so that the measuring component 4 is located closer to the forearm bracket 3, so that the subject places the right forearm on the After the forearm bracket 3, the outer sleeve 433 of the first grip 43 can be grasped by the palm. Next, the operator can adjust the spacing of the two clamp bars 48, and the two clamp bars 48 assist in positioning the forearm adjacent to the wrist. And adjusting the position of the clamping member 415 in the receiving slot 414 by the fine adjustment module 416, so that the torque meter 42, the housing 45, the adapter 46, the first grip 43, the lock seat 47 and the two clamping rods 48 and the like are all slightly displaced, until the subject feels that the wrist is in a relaxed state that has not yet been exerted. It should be particularly noted that, for some subjects whose hands are injured or whose palms are relatively thick, when the first grip 43 is adjusted to be linearly opposed to the central portion of the forearm support 3, the test is performed. The wrist of the person may be in a state of exertion, so the fine-tuning action ensures that each subject can relax and unpower the wrist in the initial state, which helps to improve the accuracy of subsequent measurement results.

Before performing the right wrist flexion/extension torque measurement, the rotation preventing member 422 of the torque meter 42 should be pushed into the rotation preventing hole 421, and the stopper 453 is pressed against the rotation stop. The end of the member 422 causes the torque meter 42 to maintain its core unrotatable.

When the measurement is started, the subject grasps the outer sleeve 433 of the first grip 43 by hand, and applies a force as if the first grip 43 is to be pushed, but the core of the torque meter 42 has been restricted from rotating. Therefore, the subject cannot actually rotate the outer sleeve 433 of the first grip 43 , but transmits the force to the force end of the torque meter 42 through the first grip 43 and the adapter 46 . E, the right wrist joint flexion moment of the subject is measured by the torque meter 42. Relatively To measure the extension of the right wrist joint, the outer sleeve 433 of the first grip 43 is biased by the back of the hand and is applied. It is understood by those of ordinary skill in the art, and thus will not be described herein.

Referring to FIG. 8 , when the right wrist joint Flexion/Extension activity angle is to be measured, the flap 453 is unscrewed, so that the rotation stop 422 of the torque meter 42 is separated from the rotation stop hole 421. The core recovery of the torque meter 42 can be rotated, so that the first grip 43 and the adapter 46 can be easily pushed and rotated about the axial direction of the connecting rod 461.

Accordingly, referring to FIG. 9, the subject can hold the first grip 43 with the palm of the hand and push the first grip 43 to rotate counterclockwise to the scale from the second housing 45b of the housing 45. Mark 455, measured the right wrist flexion (Flexion) angle of motion. Or, referring to FIG. 10, the first grip 43 is rotated clockwise by the back of the subject to measure the right wrist joint extension from the scale mark 455 on the second housing 45b of the housing 45 ( Extension) The angle of the activity.

Referring to FIG. 11 , if the torque and the angle of movement of the right wrist joint (Pronatin)/supination are measured, the two clamp rods 48 can be detached from the lock seat 47 first, and The extension arm 312 is extended beyond the length of the guiding slot 311, and the insert 413 is withdrawn from the positioning hole 3122, so that the member 45 and the like are synchronously pivoted relative to the forearm bracket 3 to extend by the extension. The positioning hole 3123 of the arm 312 is opposite to the through hole 412 of the pivoting seat 41, and the inserting hole 413 is inserted into the positioning hole 3123 to reposition the pivoting seat 41 and the extending arm 312. At this time, the torque meter 42 The axial direction is parallel to the ground.

The outer sleeve 433 of the first grip 43 is sequentially applied with a lifting force and a steering force to convert the axial direction of the first grip 43 to be orthogonal to the axial direction of the fixing rod 431. The second grip 44 is inserted into the anti-rotation hole 4612 of the adapter 46 by its insertion portion 441. Then, the operator can adjust the extension arm 312 of the forearm bracket 3 to place the right arm on the subject. After the forearm bracket 3, the grip portion 442 of the second grip 44 can be grasped by the palm. Similarly, if the subject feels that the wrist has been in a state of force, the position of the clamping member 415 in the pocket 414 can be finely adjusted by the fine adjustment module 416 until the subject feels that the wrist is still present. The state of relaxation of the output.

Before the right wrist joint (Pronatin) / Supination torque measurement, the rotation preventing member 422 of the torque meter 42 should be pushed into the rotation preventing hole 421, and the flap 453 is pressed against the The end of the rotation stop 422 is such that the torque meter 42 maintains that its core cannot be rotated.

When the measurement is started, the subject grasps the grip portion 442 of the second grip 44 by hand, and applies a force to rotate the grip portion 442 counterclockwise, but the core of the torque meter 42 is restricted from rotating. Therefore, the subject can not actually rotate the second grip 44, but the force is transmitted to the force receiving end E of the torque meter 42 through the second grip 44 and the adapter 46, and the torque is generated. Meter 42 measured the subject's right wrist joint (Pronatin) moment. In contrast, if the right wrist joint Supination moment is to be measured, the grip portion 442 is rotated counterclockwise, which is understood by those skilled in the art, and thus will not be described herein.

Referring to FIG. 12, when measuring the angle of the right wrist (Pronatin) / Supination, the flap 453 is unscrewed, so that the rotation stop 422 of the torque meter 42 is separated from the rotation. In the hole 421, the core recovery of the torque meter 42 can be rotated, so that the second grip 44 and the adapter 46 can be easily pushed and rotated about the axial direction of the connecting rod 461. .

Accordingly, the subject can grasp the grip portion 442 of the second grip 44 and rotate the second grip 44 counterclockwise to mark 455 from the second housing 45b of the housing 45. , measured the angle of rotation of the right wrist joint (Pronatin). The second grip 44 is rotated clockwise to measure the angle of motion of the right wrist joint from the scale mark 455 on the second housing 45b of the housing 45.

Please refer to Figures 13 and 14 for the wrist joint function measuring device When the subject's left wrist joint function is measured, the steering assembly 2 can accurately move the forearm bracket 3 to the left side of the seat portion 11 of the carrier 1, and is fixed on the positioning arm 13 on the left side of the carrier 1, and then Adjusting the relative position of the forearm bracket 3 and the measuring component 4 according to the item to be detected; measuring the Flexion/Extension torque and the moving angle of the left wrist joint, and measuring the left wrist joint rotation (Pronatin) The operation method of the Supination torque and the moving angle are the same as those of the aforementioned measurement of the right wrist joint, and will not be described in detail herein. It should be particularly noted that, because the forearm bracket 3 of the present embodiment has the seat plate 31 pivotally connected to the second arm 22 of the steering assembly 2, the operator can first perform the forearm bracket 3 during the direction of the transition. The steering arm 13 is turned up, the forearm bracket 3 is moved to the left side of the subject by the steering assembly 2, and the forearm bracket 3 is pressed down to the other positioning arm 13, so that the operation is intuitive. Helps improve operational convenience and efficiency.

In summary, the wrist joint function measuring device of the present invention can assist the subject to accurately output the force from the wrist to improve the accuracy of the test result; and, in the process of switching each test item, The wrist joint function measuring device accommodates the position of the subject, so that the subject can perform various wrist joint function tests without moving, thereby improving the convenience of use and the accuracy of the test result.
