Description

Technical Field

[0001] The utility model relates to the technical field of elevation pads, in particular to an elevation pad with a lifting function. Background Technique

[0002] After Achilles tendon rupture surgery, external fixation needs to be carried out for 4 - 6 weeks to ensure that the sutured tendon can heal and avoid re - rupture during the Achilles tendon healing period. In order to keep the Achilles tendon in a relaxed state, the most commonly used method at present is to apply a plaster splint in front of the lower leg, making the knee joint in a state of about 45° flexion and the ankle joint in a state of 45° plantar flexion. However, after plaster fixation, the affected limb is very heavy and its position is prone to change, resulting in compression and necrosis of the common peroneal nerve. Gravity compression easily causes pain in patients, poor blood circulation, slow wound healing, and a relatively long recovery period, bringing great trouble to the patients' lives.

[0003] An elevation pad is a nursing pad used to maintain the body position of patients before and after Achilles tendon surgery and under plaster fixation. It can be used as an auxiliary tool to improve the comfort of the legs and provide support. It is usually made of soft materials such as foam or air cushions and has grooves or slopes to adapt to the shape of the legs. The main function of the elevation pad is to lift and support the legs to relieve the pressure and compression on the leg muscles. It can help soothe leg fatigue, swelling and the feeling of heaviness, and promote blood circulation. In addition, using a leg elevation pad can also relieve problems such as varicose veins, edema and venous thrombosis in the lower extremities.

[0004] However, most of the existing elevation pads cannot be changed in length or are composed of multiple sponge pads. Since the heights and leg lengths of different patients are different, the lengths of the elevation pads required are different and need to be adjusted according to the patients' bodies. Therefore, it is necessary to always keep various models of elevation pads for people to choose and use, resulting in a certain waste. At the same time, most of the existing elevation pads are of fixed height. Since the heights of elevation pads required by different patients are different, in order to keep the patients in an ideal body position when using the existing elevation pads, it is necessary to raise the elevation pads according to the needs of different patients, increasing the workload of nursing staff.

[0005] Therefore, the technical personnel in this field provide an elevation pad with a lifting function to solve the problems raised in the above - mentioned background technique. Content of the Utility Model

[0006] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an elevation pad with a lifting function. This device can adjust the lengths and heights of each mechanism according to an individual's leg length and support the legs in the correct position.

[0007] To achieve the above object, the present utility model provides the following technical solution: An elevation pad with a lifting function, comprising a component placement mechanism, the component placement mechanism includes a placement board, and at a position near one end in the middle of both sides of the placement board, a thigh placement mechanism is rotatably arranged. The thigh placement mechanism includes a positioning rod, and at the middle of both sides of the positioning rod, a thigh telescopic plate is fixedly arranged. At one end of the thigh telescopic plate away from the positioning rod, a first connecting rod is fixedly arranged. Inside the first connecting rod, a first connector is rotatably arranged, and at the other end of the first connector, a knee joint placement mechanism is rotatably arranged;

[0008] At the other end of the knee joint placement mechanism, a second connector is rotatably arranged. At the other end of the second connector, a calf placement mechanism is rotatably arranged. The calf placement mechanism includes a second connecting rod, and at the middle of both sides of the second connecting rod, a calf telescopic plate is fixedly arranged. At one end of the calf telescopic plate away from the second connecting rod, a positioning connecting rod is fixedly arranged. Inside the positioning connecting rod, a third connector is rotatably arranged. At the other end of the third connector, an ankle joint placement mechanism is rotatably arranged. At the back of the ankle joint placement mechanism, a support rod is rotatably arranged. At the other end of the support rod, a slider is rotatably arranged, and on the upper end face of the slider, a positioning screw is threadedly sleeved.

[0009] Further, a thigh sponge pad is fixedly arranged on the upper end face of the thigh telescopic plate, and two first springs are fixedly connected to both end faces of the thigh sponge pad.

[0010] Further, first telescopic rods are respectively fixedly arranged at both ends of the positioning rod, and a first telescopic positioning member is rotatably arranged at the center of the first telescopic rods.

[0011] Further, a three-stage telescopic rod is fixedly arranged on the lower end face of the knee joint placement mechanism.

[0012] Further, a calf sponge pad is fixedly arranged on the upper end face of the calf telescopic plate, and two second springs are fixedly connected to both end faces of the calf sponge pad.

[0013] Further, second telescopic rods are respectively fixedly arranged at both ends of the second connecting rod, and a second telescopic positioning member is rotatably arranged at the center of the second telescopic rods.

It drives the second connecting rod 305 to move, thereby driving the calf telescopic plate 304 to slide. The movement of the calf telescopic plate 304 drives the change of the calf sponge pad 301 on the surface. The change of the calf sponge pad 301 drives the two second springs 308 to control the calf sponge pad 301 to remain compact, so that the calf sponge pad 301 will not be unable to retract after shortening. Both the thigh placement mechanism 1 and the calf placement mechanism 3 ensure that different patients have a suitable position for rest. The thigh placement mechanism 1 and the calf placement mechanism 3 are connected to the knee joint placement mechanism 2 through the first connector 9 and the second connector 8 to ensure that the three can rotate tangentially. The positioning connecting rod 309 slides in the sliding groove 503, and the hook surface 303 of the magic tape is connected to the loop surface 302 of the magic tape to fix the calf, ensuring that the patient will not deteriorate due to leg movement.

The first telescopic positioning member 105 is installed in the middle of the first telescopic rods 104. Rotating the first telescopic positioning member 105 controls the telescopic movement of the first telescopic rods 104. The first telescopic rods 104 drive the first connecting rod 106 to move. The first connecting rod 106 drives the thigh telescopic plate 107 to slide. The movement of the thigh telescopic plate 107 drives the change of the thigh sponge pad 102 on the surface. The change of the thigh sponge pad 102 drives the control of the two first springs 103 to keep the thigh sponge pad 102 compact. The thigh placement mechanism 1 is connected to the knee placement mechanism 2 through the first connector 9. The knee placement mechanism 2 is connected to the calf placement mechanism 3 through the second connector 8. Similarly, the second telescopic rods 306 are installed on both sides of the calf placement mechanism 3.

The movement of the second connecting rod 305 drives the calf telescopic plate 304 to slide. The movement of the calf telescopic plate 304 drives the change of the calf sponge pad 301 on the surface. The change of the calf sponge pad 301 drives the control of the two second springs 308 to keep the calf sponge pad 301 compact. The positioning connecting rod 309 slides in the sliding groove 503. The magic tape rough surface 302 is connected to the magic tape hook surface 303 to fix the calf. Secondly, a slide rail 502 is provided at one end of the storage board 501 away from the positioning rod 101. The slider 11 moves freely inside the slide rail 502. The slider 11 drives the support rod 12 to move. The movement of the support rod 12 controls the rotation of the ankle placement mechanism 4. To control the ankle placement mechanism 4 to rotate to a suitable position, the positioning screw 10 can be rotated. Rotating the positioning screw 10 can achieve positioning and ensure stable position. The telescopic movement of the three-stage telescopic rod 7 can drive the knee placement mechanism 2 to move up and down, realizing the lifting control of the knee placement mechanism 2.
