Abstract
Description
Technical Field
[0001] This invention relates to the field of ankle pump technology, and more specifically to an ankle pump exercise device with calf massage function. Background Technology
[0002] In clinical practice, many bedridden patients suffer from insufficient blood perfusion in their limbs, which can lead to neuromuscular atrophy and slowed blood flow, resulting in deep vein thrombosis in the lower extremities. These conditions seriously affect the patients' health. Ankle pump exercise devices, currently available in the technology, can effectively alleviate these problems.
[0003] Currently, the structure of ankle pump exercise devices can only promote blood circulation in the lower limbs by repeatedly flexing and extending the ankle joint, thereby driving the calf muscles to contract and relax. However, they cannot massage the calf and have poor function in relieving lower limb thrombosis. Furthermore, the patient's ankle joint rotation trajectory does not match the ankle joint movement trajectory of the ankle pump exercise device well. In other words, the patient's ankle joint rotation is not smooth, and prolonged repeated flexion and extension of the ankle joint will aggravate ankle joint wear and tear. Summary of the Invention

[0021] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0022] Reference Figures 1-7As shown, the ankle pump exercise device with calf massage function of the present invention includes a fixed base 1, a hinge device 2 located at one end of the fixed base 1, a rotating plate 3 located at one end of the hinge device 2, two sets of massage devices 4 symmetrically located at the upper end of the rotating plate 3, a flexion and extension device 5 located at the other end of the rotating plate 3, a first slide groove 6 located at the lower end of the rotating plate 3, a first slider 7 slidably located on the first slide groove 6, a second slide groove 8 corresponding to the first slide groove 6 and located at the upper end of the fixed base 1, a second slider 9 slidably located on the second slide groove 8, a connecting rod 10 rotatably located at one end on the first slider 7 and fixedly located at the other end on the second slider 9, a screw 11 passing through the second slider 9 and rotatably located at one end on the fixed base 1, and an electric motor 12 fixedly located on the fixed base 1 for driving the screw 11 to rotate; the screw 11 and the second slider 9 are threadedly engaged; the electric motor 12 is commercially available. First, fix the patient's feet on the flexion-extension device 5, with the left and right calves placed on the two sets of massage devices 4 respectively. Start the electric motor 12, driving the screw 11 to rotate, causing the second slider 9 to move. This causes the connecting rod 10 and the first slider 7 to move together, rotating the rotating plate 3. Adjust the angle of the rotating plate 3 according to the patient's needs, then stop the electric motor 12. Even if the patient's lower limbs are tilted, stretching the leg muscles and ligaments, when the flexion-extension device 5 performs reciprocating flexion-extension rotation on the patient's ankle joint, it can adapt to the patient's ankle joint, making the ankle flexion-extension movement smoother and suitable for most patients. This device significantly reduces wear and tear on the ankle joint during movement. Two sets of massage devices 4, corresponding to the patient's two lower legs respectively, massage the patient's two lower legs, greatly improving lower limb blood circulation and effectively preventing lower limb thrombosis. During the simultaneous flexion, extension, and rotation of the patient's ankle joint and the massage of the left and right lower legs, the electric motor 12, in another mode, drives the screw 11 to rotate forward and backward, causing the second slider 9 to reciprocate, thereby causing the rotating plate 3 to rotate forward and backward. Through the hinge device 2, the rotating plate 3 has a high degree of adaptability during rotation, reducing wear and tear between the ankle pump and the patient's lower limbs, while simultaneously stretching the muscles and ligaments of the patient's lower limbs.
[0023] Specifically, the hinge device 2 includes two third sliding grooves 21 located at both ends of the fixed base 1, two third sliders 22 slidably disposed on the two third sliding grooves 21, two first guide rods 23 slidably passing through the two third sliders 22 and fixed at one end to the fixed base 1, two first springs 24 respectively sleeved on the two first guide rods 23, two second guide rods 25 respectively fixed at one end at the upper end of the two third sliders 22, two bases 26 slidably sleeved on the two second guide rods 25, a rotating shaft 27 rotatably disposed on the two bases 26 at both ends, and two second springs 28 respectively sleeved on the two second guide rods 25; one end of the rotating plate 3 is fixedly sleeved on the rotating shaft 27; During the movement of the first slider 7, the second slider 9, and the connecting rod 10, the angle of the rotating plate 3 changes, causing the two third sliders 22 to move in the two third slide grooves 21 in an adaptive manner. At the same time, the two third sliders 22 move on the two first guide rods 23, causing the two first springs 24 to extend and retract in an adaptive manner, causing the two bases 26 to move on the two second guide rods 25 in an adaptive manner, and causing the two second springs 28 to extend and retract in an adaptive manner. The two ends of the rotating shaft 27 are respectively rotatably mounted on the two bases 26, and one end of the rotating plate 3 is fixedly sleeved on the rotating shaft 27, thereby causing the rotating shaft 27 to rotate in an adaptive manner, ultimately making the rotating plate 3 better suited for patient use.
[0024] Specifically, one end of each of the two first springs 24 is fixedly mounted on one of the two third sliders 22 and the other end is fixedly mounted on the fixed base 1; the two ends of each of the two second springs 28 are fixedly mounted on the two bases 26 and the two third sliders 22, respectively.
[0025] Specifically, the massage device 4 includes a fourth slide groove 41 on the rotating plate 3, a fourth slider 42 slidably disposed on the fourth slide groove 41, a first electric telescopic rod 43 fixedly disposed on the rotating plate 3 and used to drive the fourth slider 42 to move, a moving rod 44 slidably disposed through the fourth slider 42, an arc-shaped plate 45 fixedly disposed at the upper end of the moving rod 44, a plurality of massage balls 46 equidistantly spaced and rotatably disposed on the arc-shaped plate 45, and a third spring 47 fixed at one end at the lower end of the moving rod 44 and at the other end at the lower end of the fourth slider 42; the massage device 4 is connected by the first electric telescopic rod 43. The fourth slider 42 is driven to reciprocate on the fourth slide groove 41, causing the moving rod 44, the arc plate 45, the multiple massage balls 46, and the third spring 47 on the fourth slider 42 to move together, reciprocating along the direction of the patient's lower leg. The multiple massage balls 46 massage the patient's lower leg. The arc plate 45 is designed to better fit the patient's lower leg. The moving rod 44 is slidably set on the fourth slider 42, and the third spring 47 is set to allow the arc plate 45 to rise and fall adaptively. The moving rod 44 rises and falls adaptively according to the curvature of the patient's lower leg, and the third spring 47 extends and retracts adaptively.
[0026] Specifically, the bending and stretching device 5 includes a fifth slider 51 slidably mounted on the rotating plate 3, a rotating rod 52 rotatably mounted on the fifth slider 51 at one end, a frame 53 slidably mounted on the rotating rod 52, two binding components 54 symmetrically fixed on the frame 53, a fourth spring 55 fixed at both ends on the rotating plate 3 and the fifth slider 51 respectively, a fifth spring 56 mounted on the upper end of the rotating rod 52, and a power component 57 mounted on the rotating plate 3 for driving the rotating rod 52 to reciprocate; the two ends of the fifth spring 56 are respectively fixed on the rotating rod 52 and the frame 53. The binding assembly 54 includes a sixth slider 541 slidably mounted on the frame 53, a sixth spring 542 with its two ends fixed on the sixth slider 541 and the frame 53 respectively, a binding strap 543 with its two ends slidably mounted on the sixth slider 541, and a female hook and loop fastener and a female hook and loop fastener fixed at both ends of the binding strap 543 respectively. The power assembly 57 includes two fifth slide grooves 571 symmetrically arranged on the frame 53, a T-shaped plate 572 slidably arranged on the rotating plate 3 at one end, a U-shaped plate 573 slidably arranged on the T-shaped plate 572, a seventh spring 574 fixed at both ends on the U-shaped plate 573 and the T-shaped plate 572 respectively, two driven wheels 575 slidably arranged on the two fifth slide grooves 571 and rotatably arranged at both ends of the U-shaped plate 573, a spring telescopic rod 576 fixed at one end on the T-shaped plate 572, and a second electric telescopic rod 577 fixed at the other end of the spring telescopic rod 576 and the rotating plate 3 respectively. The patient's foot is bound by strap 543 and its attached Velcro straps, fixing the foot to the sixth slider 541. The heel is placed on the rotating plate 3. The sixth slider 541 is slidably mounted on the frame 53, allowing its position to be adjusted according to the length of the patient's foot. The sixth spring 542 self-adaptively extends and retracts. Then, the second electric telescopic rod 577 on the power assembly 57 is activated, pushing the spring telescopic rod 576 and the T-shaped plate 572 to reciprocate, causing the U-shaped plate 573 to reciprocate as well. The U-shaped plate 573 pushes the frame 53 to reciprocate. Through the arrangement of the rotating rod 52 and the frame 53, the rotating rod 52 rotates, and the frame 53 rotates as well, thereby causing the patient's ankle joint to perform flexion and extension movements. The fifth slider 51 is slidably mounted on the rotating plate 3, and the fourth spring 55 is also used to... The fifth slider 51 adapts to move on the rotating plate 3, the fourth spring 55 adapts to extend and retract, the frame 53 and the rotating plate 3 adapt to move, and the fifth spring 56 adapts to extend and retract, thus better adapting to the patient's ankle joint movement trajectory and making the patient's ankle joint flexion and extension movements smoother. At the same time, the sixth slider 541 adapts to move on the frame 53, and the sixth spring 542 adapts to extend and retract, further improving the smoothness of the patient's ankle joint movement. The U-shaped plate 573 and the T-shaped plate 572 adapt to move, the seventh spring 574 adapts to extend and retract, and the two driven wheels 575 move on the two fifth slide grooves 571. Thus, when the U-shaped plate 573 moves, the frame 53 and the rotating rod 52 rotate, which can also play a good role in saving effort. Through the setting of the spring extension rod 576, it adapts to the patient's ankle joint flexion and extension angle.
