specific Embodiment approach 1

[0028] The forearm twisting and wrist bending rehabilitation device of this embodiment combines figure 1 As shown, its composition includes a wearing part 7 and a control-power system 3, and the control-power system 3 includes an air source 5, a control circuit 6 and three electromagnetic air valves 4;

[0029] Wearing part 7 comprises palm support 1 and forearm support 2, wherein, palm support 1 and forearm support 2 are hinged;

[0030] The palm support 1 includes a handle 1-1 held by the palm, a palm support 1-2 for fixing the palm, and two extensible pneumatic muscles 1-3 that drive the palm support 1 for bending movement, wherein the palm support 1- 2 is arched, and the handle 1-1 is installed between the two legs 1-4 of the palm support 1-2; Legs 1-5; one end of the two extensible pneumatic muscles 1-3 is installed on the arched back of the palm support 1, and the other end is installed on the forearm support 2 to drive the palm support 1 to perform bending motion;

[...

specific Embodiment approach 2

[0034] The difference from Embodiment 1 is that in the forearm twist and wrist bending rehabilitation device of this embodiment, the palm support 1 is also provided with a layer of flexible inner lining 1-7 on the inner wall of the arched back, and the two sides of the palm support 1 The ends of the root legs 1-5 are respectively fixed and installed on the forearm support 2 by bolts.

specific Embodiment approach 3

[0036] The difference from Embodiment 1 or Embodiment 2 is that in the forearm torsion and wrist bending rehabilitation device of this embodiment, the inner wall of the armband A (part number 2-6 in the figure) is also provided with a flexible lining A (part number in the figure 2-2), arm ring A (item number 2-6 in the figure) and connecting rod A (item number 2-8 in the figure) and connecting rod B (item number 2-9 in the figure) It also has an inset shaft hole, and the inner wall of the shaft hole is provided with internal threads.

Abstract

The invention discloses a forearm turning and wrist bending rehabilitation device and a turning and bending method thereof and belongs to the field of muscular movement auxiliary devices. An existing forearm turning rehabilitation device has the problems of complicated structure, large weight and high cost. The forearm turning and wrist bending rehabilitation device comprises a wearing part (7) and a control-power system (3), wherein the control-power system (3) comprises an air source (5), a control circuit (6) and three magnetic air valves (4). According to the turning and bending method of the forearm turning and wrist bending rehabilitation device, a driving palm support (1) for stretchable pneumatic muscles (1-3) performs turnover movement so as to assist a wearer to perform wrist bending training. The stretchable pneumatic muscle drives a connecting rod A (2-8) and a connecting rod B (2-9) to deflect and further drives an arm ring A (2-6) to turn. The forearm turning and wrist bending rehabilitation device has the advantages of being simple in structure and low in cost and can perform forearm turning rehabilitation training and wrist bending rehabilitation training.

Description

technical field [0001] The invention relates to a forearm twisting and wrist bending rehabilitation device and a twisting and bending method thereof. Background technique [0002] The arm undertakes most of the work in people's life, so the arm, especially the forearm and wrist, has become one of the most important and easily injured parts of the human body, such as fractures, dislocations, and strains. In the process of rehabilitation, it can safely and effectively provide patients with continuous passive movement within a certain range of motion, which can stimulate the healing or reconstruction of articular cartilage, prevent and treat joint stiffness, and achieve the purpose of treatment and rehabilitation. At the same time, with the increasing number of patients with arm movement disorders such as hemiplegia and stroke in various countries in the world in recent years, arm movement disorders not only cause huge psychological pressure on the patients themselves and their...
