Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a stepping training device for bedridden patients. Background Art
[0002] Deep vein thrombosis refers to a disease in which blood in the deep vein system changes from liquid to solid, blocking blood reflux and causing inflammation of the vein wall. Among all types of deep vein thrombosis, lower extremity deep vein thrombosis is the most common and often occurs in long-term bedridden patients. Such patients are bedridden for a long time, lack of lower extremity activity, and slow blood flow, which can easily cause lower extremity deep vein thrombosis.
[0003] In order to prevent deep vein thrombosis of the lower limbs, long-term bedridden patients need to frequently use stepper trainers to move their lower limbs and promote venous blood return. However, existing stepper trainers cannot be placed on beds, and patients need to get out of bed and move to other rooms when using them. However, long-term bedridden patients cannot get up and walk on their own, so it is very inconvenient to use existing stepper trainers. Therefore, a stepper trainer suitable for bedridden patients is needed. Utility Model Content
