Description

Technical Field

[0001] The present invention relates to the technical field of medical rehabilitation, and particularly relates to a multifunctional upper limb trainer. Background Art

[0002] The upper limb is a multi-layered sheath-like local area formed by bones, muscles, blood vessels, nerves, and superficial and deep fasciae and skin. It can be divided into superficial and deep layer structures. The superficial layer structure is composed of skin and superficial fascia, and there are abundant superficial veins, lymphatic vessels, and cutaneous nerves in the superficial fascia. The deep layer structure is composed of deep fascia, muscles, blood vessels, nerves, and bones, and several important local structures and local core structures are formed with the blood vessels, nerves, and their paths.

[0003] After the upper limb is traumatized, especially after upper limb surgery, during the rehabilitation period, rehabilitation training for the upper limb is required. The rehabilitation training of the upper limb is different from the upper limb trainer used for fitness. The trainers for upper limb rehabilitation all have weak upper limb strength and cannot move independently. They need the assistance of equipment for traction to drive the upper limb through a reciprocating training process, promoting the exercise of the muscles and blood of the upper limb, so as to achieve the purpose of rehabilitation. Most of the existing upper limb trainers can only perform bending training of the upper arm and forearm. For the reciprocating lifting and lowering of the upper limb, the trainee needs to hold the lifting rod to move up and down. For patients with damaged hand positions, they cannot hold tightly, and during the up and down process, it is easy to have the situation of the hand slipping off, resulting in danger. For patients with different degrees of injury, the lifting height of the upper limb is different, and rehabilitation needs to be carried out step by step. Summary of the Invention

[0022] Embodiment

[0023] A multifunctional upper limb trainer. The structure on one side of the device is shown here, and the structure on the other side is the same as this one, with only the difference in the positions of the left and right upper limbs. It includes a fixed base 1. Above the fixed base 1, a hydraulic telescopic column 2 is fixedly connected. The output end of the hydraulic telescopic column 2 is fixedly connected to a column 3. On one side of the column 3, a semi-circular plate 4 is fixedly connected. On the upper surface of the column 2, a power connection line 5 is provided. On the semi-circular plate 4, a semi-circular electromagnetic slide rail 6 is provided. At the circular position of the semi-circular electromagnetic slide rail 6, a wearable device 7 is provided on the semi-circular plate 4. A control panel 8 is embedded in the semi-circular plate 4. An air pump 9 is provided inside the semi-circular plate 4. A multi-stage electric telescopic structure 10 is provided between the wearable device 7 and the slider of the semi-circular electromagnetic slide rail 6. An airbag structure 11 is provided on the inner surface of the wearable device 7. The trainee fixes the positions of the forearm, upper arm, and hand through the wearable device 7, selects the degree of rehabilitation, that is, the angle of rotation of the upper limb, on the control panel 8, inflates the airbag structure 11 through the air pump 9 to fix the upper limb. As the slider of the semi-circular electromagnetic slide rail 6 moves, it drives the straightened upper limb to lift. As the slider of the semi-circular electromagnetic slide rail 6 reciprocates, it realizes the reciprocating training of the upper limb lifting. The lifting height changes according to the movement track of the semi-circular electromagnetic slide rail 6. When forearm and upper arm bending training is required, the multi-stage electric telescopic structure 10 is activated to push the forearm to rotate, and as the multi-stage electric telescopic structure 10 reciprocates, it realizes the bending of the forearm and upper arm.

[0024] The wearable device 7 includes an upper arm sleeve 71, a forearm sleeve 72 and a glove 73. On one side of the upper arm sleeve 71, a fixed connection plate 74 is fixedly provided. On one side of the forearm sleeve 72, a movable connection plate 75 is provided. A sliding groove 76 is provided on the movable connection plate 75. A rotating base 77 is fixedly provided on the slider of the sliding groove 76. A ball bearing 78 is provided on the fixed connection plate 74. One side of the ball bearing 78 is rotatably connected to the fixed connection plate 74, and the other side is rotatably connected to the semi-circular plate 4. The fixed connection plate 74 is rotatably connected to the movable connection plate 75, and the forearm sleeve 72 is rotatably connected to the glove 73. During the reciprocating training of lifting the upper limb, the rotating base 77 is connected to the connection block 102 of the multi-stage electric telescopic rod 101. In the initial state of the multi-stage electric telescopic rod 101, the connection block 102 and the rotating base 77 are in a vertical state. As the slider of the semi-circular electromagnetic slide rail 6 moves, in the initial state, the multi-stage electric telescopic rod 101 performs a circular motion around the circle of the semi-circular plate 4, thereby driving the upper limb of the trainee to lift. When forearm and upper arm bending training is required, the output end of the multi-stage electric telescopic rod 101 supports and pushes the forearm. During the pushing process, the forearm and the upper arm bend, and mutual rotation occurs between the connection block 102 and the rotating base 77, and the rotating base 77 moves on the sliding groove 76, so that the bending degree is different. The bending degree can be adjusted by adjusting the telescopic length of the multi-stage electric telescopic rod 101.

[0025] The multi-stage electric telescopic structure 10 includes a multi-stage electric telescopic rod 101. A connection block 102 is fixedly provided at the output end of the multi-stage electric telescopic rod 101. The control end of the multi-stage electric telescopic rod 101 is fixedly connected to the connection base 103. The connection block 102 is pin-connected to the rotating base 77. The connection base 103 is pin-connected to the slider of the semi-circular electromagnetic slide rail 6. Both ends of the multi-stage electric telescopic rod 101 adopt a pin-connection method, which is convenient for mutual rotation and can also achieve mutual support, ensuring the overall stability performance.

[0026] The airbag structure 11 includes airbag units 111. Connection holes 112 are provided around the airbag units 111. The airbag structure 11 is composed of a plurality of connected airbag units 111. One of the airbag units 111 is connected to an air pump 9 through a hose. The airbag units 111 are laid on the inner surfaces of the upper arm sleeve 71, the forearm sleeve 72 and the glove 73, and are inflated and filled into the upper arm sleeve 71, the forearm sleeve 72 and the glove 73. Among them, the airbag structures 11 of the forearm sleeve 72 and the glove 73 share the same air inlet and exhaust hole, and the upper arm sleeve 71 independently uses an air inlet and exhaust hole. Using multiple air inlet and exhaust holes can quickly inflate and deflate the interior, and the airbag units 111 are used to squeeze the upper limb of the trainee to achieve fixation.

[0027] Both the fixed connection plate 74 and the movable connection plate 75 are provided with air pump connection holes. One end of the air pump connection hole is connected to the air pump 9 through a hose, and the other end is connected to the connection hole 112 on one side of the airbag unit 111 through a hose, which is convenient for the air pump 9 to inflate and deflate.

[0028] On the semi-circular plate 4, a rotation angle scale is provided on one side of the semi-circular electromagnetic slide rail 6. The semi-circular electromagnetic slide rail 6, the multi-stage electric telescopic rod 101, and the air pump 9 are all electrically connected to the control panel 8. The control panel 8 is provided with a CPU control center. A storage battery is provided inside the semi-circular plate 4. The rotation angle scale can allow the trainee to clearly know their training intensity and lifting height, which is convenient for progressive rehabilitation training. The CPU control center performs data analysis and processing to achieve high automation.

[0029] Working principle:

[0030] As shown in the figure, when in use, the trainee can choose to train the left arm or the right arm alone according to their upper limb conditions, or can choose to use both sides of this device at the same time for training. The trainee inserts the upper limb into the wearing device 7. After the forearm, upper arm, and hand reach the corresponding positions, the doctor or the trainee's other arm operates the control panel 8 to start the air pump 9. The air pump 9 inflates the airbag structure 11 to fix the trainee's upper limb. After the fixation is completed, the trainee can choose upper limb bending training or upper limb lifting training;

[0031] For upper limb bending training, the trainee straightens the arm and starts the multi-stage electric telescopic rod 101. As the multi-stage electric telescopic rod 101 starts, the multi-stage electric telescopic rod 101 pushes the forearm sleeve 72, causing the forearm sleeve 72 to rotate with the upper arm sleeve 71. Through the control panel 8, the extended length of the multi-stage electric telescopic rod 101 can be selected, thereby adjusting the bending degree. The reciprocating telescoping of the multi-stage electric telescopic rod 101 realizes repeated upper limb bending training;

[0032] For upper limb lifting training, the semi-circular electromagnetic slide rail 6 is started through the control panel 8. As the slider of the semi-circular electromagnetic slide rail 6 moves, it drives the multi-stage electric telescopic rod 101 to move, so that the wearing device 7 rotates around the center of the semi-circular electromagnetic slide rail 6. As the slider of the semi-circular electromagnetic slide rail 6 slides upward, the lifting height changes. By controlling the movement range of the slider of the semi-circular electromagnetic slide rail 6, the adjustment of the upper limb lifting height is controlled.

[0033] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
