There are 1.2-1.5 million new cases of stroke in China every year, and 0.8-1 million people die, with a mortality rate of 66.7%. This disease has hemiplegia symptoms, which will cause the loss of limb motor function, especially the loss of upper limb motor function, which greatly affects the daily life of patients.

[0003] Patients who need to recover from injuries must use a flexion and extension training device during recovery training. However, current flexion and extension training devices are mostly active, that is, the user actively exerts force to flex and extend the elbow. However, for patients who have not been flexing and extending for a long time, sudden active flexion and extension not only cannot quickly adapt to the arm, but also increases the patient's pain, and even causes the patient to resist recovery training. Therefore, passive recovery training is also crucial before the patient actively recovers, which can help the muscles and joints on the arm adapt to flexion and extension without force, thereby laying a foundation for active recovery training.

It presets the usage time for each session and displays the recorded data for the patient's convenience. The angle measuring device is used to measure the angle between the upper arm fixation plate 1 and the forearm fixation plate 2. Both the recording control device and the angle measuring device adopt existing technology, and their specific structures and principles are also existing technologies. This embodiment does not make any improvements to them, so they will not be described again.

[0040] Example 2: Considering that the training device consisting of the upper arm fixing plate 1, the forearm fixing plate 2 and the drive mechanism 3 in Embodiment 1 has a relatively simple function and poor training effect, this embodiment adds a synchronization component 303 on the basis of Embodiment 1. The synchronization component 303 is connected to the massage mechanism 4 and drives the massage mechanism 4 to work.

[0041] The massage mechanism 4 is mounted on the forearm fixation plate 2 and connected to the drive mechanism 3. It is used to massage the forearm, so that the patient's forearm is massaged while the patient's arm is flexing and extending, thereby increasing blood circulation and enhancing the training effect.

[0042] For details, please refer to the attached document. Figure 6 As shown, the synchronization component 303 is connected to the inner side of the drive plate 3023 connected to the forearm fixing plate 2. When the drive plate 3023 moves, it drives the synchronization component 303 to work.

[0066] At the same time, when the driving plate 3023 moves upwards, the hinged plate group 3031 moves upwards, the hinged plate group 3031 drives the two sliding blocks 3032 to move in opposite directions, thereby stretching the spring on the stretching elastic assembly 3033 and pulling the pull rope 3034, the pull rope 3034 is stretched to drive the moving plate 401 to move and stretch the spring 4011, the moving plate 401 moves backward to drive the impact column 4012 to impact the moving rod group 4031, so that the moving rod group 4031 moves along the adjusting groove 4032, so that the massage ring 402 moves left and right and also rotates, and the massage of the patient's small arm in the horizontal and vertical directions is realized.

[0067] Meanwhile, when the moving plate 401 moves, the wrist fixing support 501 is made to reciprocating rotate by extruding the driving groove 5011 which is in a slope, and then drives the patient's wrist joint to train. When the wrist fixing support 501 reciprocating rotates, the inflatable member 5022 is driven to rotate. Under the extruding effect of the fixed push rod 5024, the piston rod of the inflatable member 5022 is extruded, so that the injection tube fills the inflatable air bag 5023 with air, and the inflatable air bag 5023 expands, and then drives the patient's fingers to open, and massages the patient's palm at the same time. When the wrist fixing support 501 rotates in the opposite direction, the force of the fixed push rod 5024 on the piston rod decreases, the inflatable air bag 5023 retracts, the patient's fingers naturally close, the gas in the inflatable air bag 5023 is extruded into the injection tube, and then drives the piston rod to move outwards, and returns to the initial state.
