Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation treatment instruments, in particular to an arm rehabilitation assistance device. Background Art

[0002] Most patients with arm injuries (such as arm fractures or arm ligament strains) need surgical treatment, and rehabilitation training after surgery is also extremely important. If the arms of postoperative patients remain immobile for a long time, the arm muscles will gradually atrophy. Therefore, it is very necessary to carry out targeted rehabilitation exercises on the arms of patients after surgery, which can accelerate the recovery of the patients' arms and promote the restoration of arm functions. When patients perform arm rehabilitation training, due to their own weakness, they cannot spontaneously perform recovery training of a certain intensity, so they cannot achieve the corresponding exercise effect. There is a need for a device that can help patients perform arm rehabilitation training, and at the same time, this device can also help the elderly with rigid arm ligaments perform rehabilitation training.

The support rods 1.2.3 correspond to the support feet 1.2.2 one by one, and both ends of the support rod 1.2.3 are respectively hinged to the support foot 1.2.2 and the lower end of the outer tube 1.1.1. The hinge joint of the support rod 1.2.3 and the support foot 1.2.2 is located in the middle of the support foot 1.2.2 in the axial direction. It should be noted that the lower end of the support foot 1.2.2 contacts the ground to support the folding bracket 1, avoiding the lower end of the central tube 1.1 from abutting against the ground and ensuring the stability of the folding bracket 1. Through the arrangement of the sliding sleeve 1.2.1, when the folding bracket 1 is not in use, the sliding sleeve 1.2.1 slides upward, driving the support rod 1.2.3 to rotate, so that the support foot 1.2.2 retracts and is stored, reducing the occupied space and having a high portability.

[0053] In some embodiments, as Figures 1-4 shown, a first through groove 3.3.3 is provided on the first vertical portion 3.3.2, and a second through groove 3.4.3 is provided on the second vertical portion 3.4.2. One end of the first strap 3.2 is connected to the second through groove 3.4.3, and the other end of the first strap 3.2 passes through the first through groove 3.3.3 and then folds back to adhere to the body of the first strap 3.2; a third through groove 4.3.3 is provided on the third vertical portion 4.3.2, and a fourth through groove 4.4.3 is provided on the fourth vertical portion 4.4.2. One end of the second strap 4.2 is connected to the fourth through groove 4.4.3, and the other end of the second strap 4.2 passes through the third through groove 4.3.3 and then folds back to adhere to the body of the second strap 4.2. It should be noted that the arrangements of the first strap 3.2 and the second strap 4.2 make the connection between the arm and the auxiliary component tight, preventing the arm from detaching from the first accommodation cavity 3.1 and the second accommodation cavity 4.1 during the rehabilitation exercise, with stronger stability. At the same time, the first strap 3.2 and the second strap 4.2 can be adjusted according to the thickness of the arm, having good applicability.

[0054] In some embodiments, as Figures 1-4 shown, protective pads 9 are provided on the wall surfaces of the first accommodation cavity 3.1 and the second accommodation cavity 4.1. It should be noted that this enables the user not to directly contact the wall surface of the auxiliary component. The protective pads 9 have better protection and softness, resulting in a better user experience.

[0055] The whole device is painted with varnish to enhance the hardness, wear resistance, corrosion resistance of the coating, and improve its gloss and color saturation.

[0056] Working principle: Slide the sliding sleeve 1.2.1 to make the supporting feet 1.2.2 expand. Place the folding bracket 1 at the position required by the user. Tighten the first locking bolt 1.3 to make the connection between the outer tube 1.1.1 and the sliding sleeve 1.2.1 more stable. Slide the inner tube 1.1.2 to the required height and tighten the second locking bolt 1.4 to position the inner tube 1.1.2. Place the arm that needs rehabilitation exercise at the first accommodating cavity 3.1 and the second accommodating cavity 4.1. Move the front moving plate 3.4 and the rear moving plate 4.4 to the appropriate positions. Rotate the handle 10.1 to limit the front moving plate 3.4 and the rear moving plate 4.4. At the same time, tighten the first strap 3.2 and the second strap 4.2. Rotate the arm to make the forearm sleeve 3 rotate, thus realizing the rehabilitation exercise of the arm.
