Problems solved by technology

The CPM machine currently used in the market drives the knee joint to bend through the contraction of the lever, but the external force provided by the electric motor cannot be changed according to the patient's ability to bear, which may easily cause leg fatigue or even secondary injury, and the maximum angle of rehabilitation does not exceed 90 degrees
[0003] Chinese patent 201020149255.1 discloses a knee joint functional exerciser, which uses the gravity of the calf itself to make the knee joint swing for exercise. This method can promote the blood circulation of the knee joint, restore the flexibility of the knee joint and improve the stiffness of the lower limb muscles , but the effect on changing the stiffness of the knee joint is not obvious
But none of these patents can train the flexibility of the knee joint and the muscles of the lower limbs

Embodiment 1

[0034] refer to figure 1 , Figure 4 as well as Figure 5 , the present embodiment comprises underframe, vertical rod, swing rod and push rod, and the upper left and right sides of the upper part of vertical rod are all provided with thigh support rod 1, and the front upper part of vertical rod is provided with fixed block; The front end is connected; the upper part of one side of the swing rod is provided with a rotating connecting rod 2, and the lower end of the other side of the swing rod is provided with a pedal 3; the rotating connecting rod 2 is connected with the fixed block in rotation; 1 flush; the upper end of the swing rod is provided with a push rod fixing block 4, the upper end surface of the push rod fixing block 4 is an arc surface, and the arc surface is evenly provided with a number of push rod connecting rods 5; the push rod connecting rod 5 and the lower end of the push rod match.

[0035] refer to figure 2 as well as image 3 , the left and right side...

Embodiment 2

[0047] The only difference between this embodiment and Embodiment 1 is that this embodiment performs single-leg training, and a single swing bar and a push rod corresponding to the swing bar are selected.

Embodiment 3

[0049] The only difference between this embodiment and Embodiment 1 is that the seat plate 12 and related accessories of the seat plate 12 are not used, the patient extends the bottom frame under the bed and independently adjusts the distance between the thigh support bar 1 and the bed, adjusts the vertical bar The length makes the thigh support bar 1 flush with the bed surface, and the patient can sit directly on the bed for rehabilitation training.

Abstract

The invention discloses a portable exercise device for reducing the rigidity of knee joints and improving the flexibility thereof and a method for applying the portable exercise device.The portable exercise device comprises a bottom frame, an upright rod, swing rods and push rods.Thigh support rods are arranged on the left side and the right side of the upper portion of the upright rod, and a fixing block is arranged on the front upper portion of the upright rod; the lower end of the upright rod is connected with the front end of the bottom frame; a rotary connecting rod is arranged on the upper portion of one side of each swing rod, and a pedal is arranged at the lower end of the other side of each swing rod; the rotary connecting rods are rotationally connected with the fixing block; the rotation central axes of the rotary connecting rods are parallel to the thigh support rods; push rod fixing block are arranged at the upper ends of the swing rods, arc surfaces are arranged on the upper end surfaces of the push rod fixing blocks, and a plurality of push rod connecting rods are uniformly arranged on the arc surfaces of the push rod fixing blocks; the push rod connecting rods are matched with the lower ends of the push rods.The portable exercise device and the method have the advantages that the portable exercise device is simple in structure and wide in application range and is safe and reliable, the rigidity of the knee joints can be effectively reduced, and the flexibility of the knee joints can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a portable exercise device for improving the stiffness and flexibility of the knee joint and a method for using it. Background technique [0002] Clinically, after knee joint or lower extremity surgery, it is necessary to train the patient's knee joint to help them recover their activities. Knee joint rehabilitation training includes knee joint flexion training and knee joint flexibility training. Both types of training use external force to make the knee joint move passively, and the function of the knee joint is gradually restored through long-term training. The CPM machine currently used in the market drives the knee joint to bend through the contraction of the lever, but the external force provided by the electric motor cannot be changed according to the patient's ability to bear, which may easily cause leg fatigue or even secondary injury, and the maximum angle of re...
