Description

Technical Field

[0001] The present application relates to the field of upper limb rehabilitation training robots, and in particular to an upper limb rehabilitation training robot. Background Art

[0002] The upper limb rehabilitation training robot is a device that combines computer virtual technology and rehabilitation medicine theory. It aims to help patients restore upper limb function by simulating the movement patterns of the human upper limbs. This device is mainly suitable for patients with upper limb dysfunction caused by stroke, craniocerebral injury, spinal cord injury, peripheral nerve injury, bone and joint diseases, cerebral palsy in children, etc. The working principle of the upper limb rehabilitation training robot is based on the principle of neuroplasticity. By simulating the movement patterns of the human upper limbs in real time, patients perform multi-joint or single-joint rehabilitation training in a computer virtual environment. This training method can not only eliminate or reduce the influence of gravity, but also provide real-time intuitive visual feedback, thereby enhancing the training effect. When in use, a conventional upper limb rehabilitation training robot moves the body to a suitable position. A control frame is installed on the top of the body. Two mounting frames are connected to the surface of the control frame. The mounting frame is used to fix the patient's arm, and the body controls the control frame to move the patient's arm to complete the training and rehabilitation of the patient's arm.

[0003] Regarding the above-mentioned related technologies, the inventor believes that when conventional rehabilitation training robots are in use, due to the large flow of people in the hospital, when the patient's arm is controlled to move, it is easy for outsiders to walk into the swing range of the patient's arm, causing the patient's arm to touch outsiders or objects, causing secondary injury to the arm or injury to outsiders.
