Problems solved by technology

Its disadvantages: the lower limb rehabilitation device prevents the formation of deep vein thrombosis in the lower limbs by stepping on both feet (like riding a bicycle), but the way of stepping on exercise cannot realize the effect of the body's own pumping blood to dredge the blood vessels, so the effect is minimal; secondly, For patients with lower limb injuries, the rehabilitation device is not suitable

Embodiment 1

[0009] Embodiment 1: with reference to attached figure 1 . A device for preventing deep vein thrombosis of lower extremities, one end of the bottom plate 8 is hinged to one end of the moving plate 6, the electric screw rod 1 is fixed on the other end of the bottom plate and the upper end of the screw rod of the electric screw rod 1 is connected to the other end of the moving plate, and the electric screw rod 1 The signal input terminal is connected to the signal output terminal of the controller 5, the servo motor 2 is fixed on the moving plate 6 and the power output shaft of the servo motor is connected with the foot plate drive shaft 4, the foot plate drive shaft 4 is fixedly connected with the foot plate 3 and the foot plate 3 is provided with a fixed foot Belt, the servo motor 2 signal input terminal is connected to the controller 5 signal output terminal.

[0010] One end of the bottom plate 8 and one end of the moving plate 6 are hinged by a joint surface 9 . A high-de...

Embodiment 2

[0011] Embodiment 2: On the basis of Embodiment 1, the controller 5 can also use two travel switches (not shown) to contact the foot plate 3 to realize the forward rotation of the foot dorsiflexion and reverse plantar flexion of the foot plate 3 . This control structure and method are used in the prior art, and will not be described in detail here.

Embodiment 3

[0012] Embodiment 3: On the basis of Embodiment 1, the controller 5 can also use the red line switch (not shown) to be tangent to the foot plate 3 to realize the forward rotation of the foot dorsiflexion and reverse plantar flexion of the foot plate 3 . This control structure and method are used in the prior art, and will not be described in detail here.

Abstract

The invention relates to a device and method for preventing formation of lower limb deep vein thrombosis. One end of a bottom plate is hinged to one end of a movable plate, an electric lead screw is fixed to the other end of the bottom plate, the upper end of the electric lead screw is connected with the other end of the movable plate, and the signal input end of the electric lead screw is connected with the signal output end of a controller; and the servo motor is fixed on the movable plate, a power output shaft of the servo motor is connected with the foot plate driving shaft, the foot plate driving shaft is fixedly connected with the foot plate, and a signal input end of the servo motor is connected with a signal input end of the controller. The device has the advantages that formation of deep vein thrombus of the lower limbs of the patient is effectively avoided, and the device can meet the requirements of initial dorsal stretching or plantar flexion of the feet of different patients by adjusting the forward and reverse rotation angles of the servo motor; and secondly, the amplitude of foot dorsal stretching and plantar flexion of the patient is gradually enhanced by adjusting the rotating angle of the servo motor, so that the flowing power of blood is improved, and the formation of deep vein thrombosis of the lower limbs of the patient is directly avoided.

Description

technical field [0001] The invention relates to a device and method for preventing deep vein thrombosis of lower limbs, which can quantitatively set the movement state and amount of lower limbs according to human body indicators, and belongs to the field of medical rehabilitation equipment manufacturing. Background technique [0002] CN205698329U, title "a lower limb rehabilitation device for bed", comprising a support frame composed of horizontal support and longitudinal support, a vertical support is installed on the support frame, a backboard is fixed on the vertical support, and a movable support is provided on the top of the vertical support. The slider that slides up and down, one side of the slider is connected with the head of the bed locking bracket, the locking plate is connected with the locking bracket of the head of the bed through the locking nut at the head of the bed, and a support plate is arranged between the longitudinal support and the vertical support. T...
