Technical Field

[0001] The utility model relates to the technical field of health care equipment, in particular to an auxiliary rehabilitation device for critically ill bedridden patients in an ICU. Background Art

[0002] Bedridden patients are caused by many reasons, such as limb paralysis caused by stroke, limb joint stiffness caused by surgical sequelae, joint dysfunction caused by hand trauma, etc. For some bedridden patients, especially those with more serious conditions, due to their lack of ability to exercise independently, they need caregivers to help them with limb activities to prevent diseases such as lung infection, muscle atrophy, and thrombosis.

[0003] However, due to the different body shapes of different patients, when performing limb activities for larger patients, especially leg activities, it is difficult for nursing staff with less strength to complete the patient's leg activities alone. The actual operation is rather laborious, and it is difficult to complete frequent daily limb rehabilitation exercises. In view of this, we propose an auxiliary rehabilitation device for critically ill bedridden patients in the ICU. Utility Model Content
