Abstract
Description
Technical Field
[0001] This utility model relates to the field of rehabilitation training equipment technology, and in particular to an upper limb flexion and extension training device. Background Technology
[0002] After recovering from upper limb injury or illness, patients need to perform flexion and extension exercises with the help of rehabilitation training equipment to restore joint and muscle function. In existing technologies, such as the upper limb traction rehabilitation stretching device disclosed in patent CN209695496U, the lengths of the left and right sleeves need to be adjusted according to the patient's arm length. The patient's arm is then inserted into the left sleeve and exits from the right end of the right sleeve. The medical staff then grasps the handle and slowly slides the slide block to the right. The slide block moves to the right, causing the right sleeve to rotate to the right. This rotation pulls on the second spring, creating a stretching force. The right sleeve's rotation further extends the patient's arm to the right, performing traction rehabilitation stretching.
[0003] The above-mentioned device has at least the following two drawbacks:
[0004] 1. When using it, the entire arm needs to be inserted into the left and right cannulas. However, since the patient's arm has not yet fully healed, the action of inserting the arm into the cannulas is difficult and inconvenient for the patient.
[0005] Second, although there is the assistance of springs, medical staff are still needed to help with the use of the device, and it cannot be used independently to complete the training.
[0006] In conclusion, existing upper limb rehabilitation training devices need improvement. Utility Model Content
