[0003] Although the existing technology can be fixed to the bed, during the working process, the whole needs to be operated manually, which increases the labor intensity of medical staff or patients' families, wastes manpower and time, and reduces the efficiency of the overall installation. The overall manual clamping operation has low accuracy, which may cause safety hazards during later movement, and it is inconvenient to perform quick position adjustments, making the overall operation inconvenient.

[0004] In view of the above problems, it is urgently necessary to carry out innovative design based on the original exercise assist device for mechanically ventilated patients. Therefore, we proposed that the exercise assist device for mechanically ventilated patients can solve the above problems well. Summary of the invention
