Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a lower limb exercise device for preventing lower limb venous thrombosis. Background Art

[0002] Deep vein thrombosis of the lower limbs refers to the coagulation of blood in the deep veins of the lower limbs to form a blood clot, which can also be referred to as deep vein thrombosis of the lower limbs. Therefore, it is necessary to constantly exercise the lower limbs to promote blood circulation in the lower limbs through exercise, thereby effectively preventing the occurrence of deep vein thrombosis.

[0003] Patent application number CN202020324205.6 is an exercise and care device for preventing deep vein thrombosis. By designing a column rod, an inclined rod, an armrest ring, a guide rod, a folding skateboard slidably connected to the guide rod, a spring sleeved on the guide rod, the bottom of the guide rod is fixedly connected to the top of the base plate, and the top of the guide rod passes through the folding skateboard, when the exerciser fixes his feet in the above manner, the exerciser bends his legs and exerts force downward, at this time, the spring is compressed, and the exerciser carries the shoe-shaped pedal to move downward, and the shoe-shaped pedal slides downward relative to the guide rod. When the exerciser stops moving, the exerciser resets under the elastic restoring force of the spring, and at the same time, the exerciser holds the armrest ring and exercises in the above manner. Under the above-mentioned movement, the end of the exerciser is constantly bent and constantly exerts force downward, thereby realizing continuous exercise of the exerciser's legs; however, when the exerciser uses it, long-term exercise causes physical fatigue, affects physical health, and the device cannot be moved and is too cumbersome to carry.
