Description

Lower limb decompression therapy device

technical field

The invention relates to a medical auxiliary device, in particular to a double lower limb decompression treatment device for aseptic necrosis of the femoral head, degenerative change of the knee joint and fracture of the lower limbs.

Background technique

The degenerative changes of the knee joint, the causes, treatment and prevention of femoral head necrosis are all inseparable from reducing the load on the joints. At present, oral medication can only temporarily relieve pain. Surgical treatment is risky for the elderly, and some patients cannot undergo surgery due to other physical reasons. However, if the patient's joint load is reduced, the patient's pain symptoms can be significantly relieved, and the progression of the disease can be delayed, and even the patient's pain can be completely relieved. At present, bed rest, crutches, and canes are often used to reduce the joint weight of patients; long-term bed rest has a greater impact on patients, and long-term bed rest complications are prone to occur; it is not only inconvenient for patients to use crutches, crutches, and patients are less medically compliant. Difference. Therefore, it is very necessary to design an easy-to-use device that can reduce the load on the patient's knee and hip joints without lying on the bed, for patients with degenerative changes of the knee joint and necrosis of the femoral head.

Contents of the invention

The purpose of the present invention is to provide a double lower limb decompression therapy device, which can reduce the load on the patient's lower limbs, adjust the line of force of the lower limbs, and relieve the pain symptoms caused by the weight bearing.

To achieve the above object, the present invention can take the following technical solutions:

To achieve the above object, the present invention takes the following technical solutions:

The double lower limbs decompression treatment device of the present invention comprises a thoracolumbar fixing belt, and the lower edge of the thoracolumbar fixing belt is hinged with two human lower limb decompression mechanisms with the same structure; the human lower limb decompression mechanisms all include: The first support rod and the second support rod hinged at its lower end, and the buffer pedal hinged at the lower end of the second support rod; a hydraulic strut is hinged between the first and second support rods; the buffer foot The pedal is a hollow interlayer structure provided with a hydraulic chamber, and a plurality of piston penetration holes are evenly distributed on the lower plate surface of the hollow interlayer, and the piston penetration holes are tube structures extending into the hydraulic chamber. Piston cavities are formed, pistons are respectively arranged in each of the piston cavities, and the piston rods of the pistons extend downward out of the lower plate surface of the hollow interlayer.

The lower end of each piston rod extends 1cm-3cm from the lower surface of the hollow interlayer, and a plastic anti-skid pad is respectively fixed at the lower end of each piston rod; between the first and second support rods and the buffer pedal The human thigh fixing belt, the lower leg fixing belt and the shoe fixing belt are respectively arranged on the board.

A shroud for fixing shoes is arranged along the upper edge of the cushioning pedal of the hollow sandwich structure.

The first and second support rods are telescopic rod structures; a plurality of support vertical plates are arranged at intervals on the thoracolumbar fixing belt.

The buffer pedal is provided with a hydraulic adjustment valve for adjusting the pressure in the hydraulic chamber.

The present invention has the advantage of transmitting the force acting on the lower limbs of the human body to the thoracolumbar fixing belt through force transmission, thereby treating hip and knee joint pain in a physical way, so that the patient can especially go up and down steps and squat down when walking. It can reduce the pressure on the hip joint and knee joint, achieve the purpose of treating joint pain and delaying the development of the disease.

detailed description

As shown in Figures 1-3, the double lower limbs decompression therapy device according to the present invention includes a thoracolumbar fixing belt 1, and eight supporting vertical boards 2 are arranged at intervals on the thoracolumbar fixing belt 1. Two human body lower limb decompression mechanisms with the same structure are hinged on the lower edge at the distance between the two crotches of the human body; 4, and a buffer pedal 5 hinged at the lower end of the second support rod 4; the first and second support rods 3 and 4 are telescopic structures with adjustable length and made of high-strength aluminum alloy; 1. There is a hydraulic support rod 6 hinged between the second support rods 3 and 4, and the hydraulic support rod 6 is located on the outside of the first and second support rods 3 and 4. The setting of the hydraulic support rod 6 is to prevent the knee joint of the patient from walking Out of control, play a role in protecting patients. As shown in Figure 2, the buffer pedal 5 is a hollow interlayer structure provided with a hydraulic chamber 7, and a plurality of piston penetration holes are evenly distributed on the lower plate surface of the hollow interlayer. The extended lumen structure is used to form the piston cavity 8, and a piston 9 is respectively arranged in each piston cavity 8, and the piston rod 10 of the piston 9 extends downward from the lower plate surface of the hollow interlayer by 1cm-3cm, and each piston rod 10 The lower ends of each are fixed with plastic anti-skid pads 11 respectively. The first and second support rods 3, 4 and the buffer pedal 5 are respectively provided with a human body thigh fixing belt 12, a calf fixing belt 13 and a shoe fixing belt 14; On the pedal 5 , a shroud 15 is arranged along the upper edge of the buffer pedal 5 .

When the present invention is used, first adjust the lengths of the first support rod 3 and the second support rod 4 according to the distance from the patient's hip joint to the knee joint and the distance from the knee joint to the ankle joint, so as to adapt to the length of the patient's thigh and calf; Then the thoracolumbar fixing belt 1 is fixed on the patient's waist and chest position, the first support rod 3 and the second support rod 4 are respectively placed outside the patient's two lower limbs, and the patient's feet are placed in the hoarding 15 of the cushioning pedal 5, and the hydraulic pressure Regulating valve regulates the hydraulic buffer pressure of buffer pedal 5; Finally, fix firmly with patient's thigh and calf shoes by thigh fixing belt 12, calf fixing belt 13 and shoes fixing belt 14 and get final product.

When the patient walks, the piston rod 10 extending 1cm-3cm from the lower surface of the hollow interlayer acts as a hydraulic buffer, and the buffered force is transmitted to the thoracolumbar fixing belt through the first support rod 3 and the second support rod 4, Therefore, the patient greatly reduces the pressure on the hip joint, knee joint and ankle joint in the process of walking, so as to achieve the purpose of treating joint pain and delaying the progression of the disease.
