Lower limb function exercise instrument for a bedridden patient

Abstract

The invention discloses a lower limb function exercise instrument for a bedridden patient. A main machine is connected with a first transmission arm assembly and a second transmission arm assembly, the first transmission arm assembly and the second transmission arm assembly are arranged side by side corresponding to the two legs of a patient and are telescopic, and a first pedal and a second pedalare connected with the ends, close to a bed head, of the first transmission arm assembly and the second transmission arm assembly through ball universal joints respectively. When the main machine isnot started, a bedridden patient capable of autonomously moving steps on the first pedal and the second pedal to drive the first transmission arm assembly and the second transmission arm assembly to move for exercise. When the main machine is started, the feet of a bedridden patient without autonomous activity are fixed to the first pedal and the second pedal, the main machine drives the first pedal and the second pedal to move through the first transmission arm assembly and the second transmission arm assembly, and the functional exercise requirements of the bedridden patient without autonomous activity are met. The instrument is portable, easy to operate and capable of effectively helping a bedridden patient to prevent and reduce formation of lower limb deep venous thrombosis.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a lower limb function exerciser for bedridden patients. Background technique [0002] Deep vein thrombosis of the lower extremities has been paid much attention clinically. Except for a few that can ablate spontaneously or be limited to the site of occurrence, most of them will spread to the main deep veins of the entire limbs, and can also extend centripetally to the inferior vena cava, and even block the renal veins. Cause renal failure, thrombus falls off and cause pulmonary embolism, which is life-threatening, and clinically successful rescue cases are very rare. Deep venous thrombosis of lower extremities often occurs in bedridden patients. Therefore, it is very important to perform lower extremity functional exercises on bed in bedridden patients to prevent lower extremity venous thrombosis. Proper functional exercise of lower extremities in bed can greatly reduce t...

AI Technical Summary

Problems solved by technology

[0003] At present, simple lower extremity air pressure therapy is mostly used to passively prevent lower extremity deep vein thrombosis, such as air pressure wave therapy equipment. However, due to the size and price of this type of air pressure therapy equipment, the number of general clinical departments is limited, and the treatment time and frequency of patients are affected by the cost. Due to the limitation of the number of machines and machines, the effect of preventing deep vein thrombosis of the lower limbs is limited, and it cannot meet the requirements of patients for lower limb functional exercise.
