Description

Technical Field

[0001] This utility model relates to the technical field of medical and nursing devices, and in particular to an auxiliary exercise device for medical and nursing care. Background Technology

[0002] Medical assistive exercise devices are devices used to help patients exercise and rehabilitate. They are usually set up and supervised by medical professionals (such as physical therapists or rehabilitation therapists) according to the patient's condition. These devices are designed to assist patients in safe, effective and customized exercises to restore motor function, improve muscle strength, improve joint stability, etc.

[0003] During the recovery phase after humeral head fracture surgery, patients need to receive massage and manipulation from doctors and nurses at regular intervals. Patients also need to bend their arms to promote blood circulation and fracture healing. However, bending the arm is very painful for patients in the recovery period, usually requiring nurse assistance. Without supervision, patients are unwilling to train on their own. Furthermore, the heavy workload of medical staff makes it difficult to supervise at all times, leading to patients becoming lax in their exercises and hindering their recovery.

[0004] Currently, no effective solutions have been proposed for the problems of arduous rehabilitation work, patient apathy, and long rehabilitation cycles in related technologies. Utility Model Content

[0211] Twist the locking element 71 counterclockwise so that it rotates along the circumference of the connecting element 53 and moves away from the second placement element 61 along the axial direction of the connecting element 53 until it separates from the second placement element 61, thereby putting the second placement element 61 in a relaxed state.

[0212] Push the second placement element 61 so that it moves accordingly along the length direction of the first sliding element 52 via the second sliding element 62, thereby adjusting the distance between the second placement element 61 and the first placement element 11.

[0213] Once the position is adjusted to the appropriate level, turn the locking element 71 clockwise to rotate it around the circumference of the connecting element 53 and move it towards the second placement element 61 along the axial direction of the connecting element 53 until it comes into contact with the second placement element 61, thereby securing the second placement element 61.

[0214] (II) Preparation

[0219] (III) Arm bending operation

[0220] The drive element 21 is activated, causing the first linkage element 22 to move horizontally toward the first placement element 11. The first linkage element 22 drives the third linkage element 41 to rotate clockwise around the first rotating element 14 via the second linkage element 32. The third linkage element 41 drives the second placement element 61 to rotate accordingly via the mounting element 51, thereby driving the forearm to rotate accordingly with the elbow as the fulcrum.

[0221] Finally, the arm bending operation is completed.

[0222] The advantages of this invention are that the coordinated use of the first linkage unit, the second linkage unit, the third linkage unit, and the placement unit can drive the placement unit to rotate accordingly, thereby causing the forearm placed on the placement unit to move accordingly, thus achieving the rehabilitation work of arm bending, replacing manual supervision, improving the convenience of the rehabilitation process, and facilitating patient recovery; the coordinated use of the mounting unit and the locking unit can adjust the distance between the base unit and the placement unit, allowing for corresponding adjustments according to the patient's arm length, to adapt to different patients' use of this auxiliary exercise device, thus improving the practicality of the auxiliary exercise device.
