Technical Field
[0001] The present invention relates to the technical field of medical devices, and more particularly to a lower limb deep vein thrombosis prevention and treatment training device. Background Art
[0002] After deep vein thrombosis (DVT) forms in the lower extremities, the venous lumen is primarily obstructed by thrombus masses. Therefore, clinical care requires the prevention of thrombus dislodgement. This is because in the early stages of thrombosis, the thrombus is relatively loose. If a thrombus dislodges under stimulation and flows along the entire deep venous circulatory system toward the proximal vena cava, atrium, or lungs, it can lead to pulmonary embolism in severe cases, causing the patient to suddenly lose their breath, resulting in respiratory arrest and even life-threatening consequences. In clinical care, the prevention of thrombus dislodgement often involves a combination of medication and rehabilitation exercises. The best form of rehabilitation exercise is foot pump exercises, which involve continuous ankle movement to promote blood flow restoration and improve blood return to the lower extremities. Rehabilitation for DVT in the lower extremities is often supplemented with medical machine-assisted training.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0030] See also Figures 1-9The present invention provides a lower limb deep vein thrombosis prevention and treatment trainer, comprising a support plate 1 and a pair of brackets 2 fixedly connected to the support plate 1, the brackets 2 are provided with mounting holes and gaskets, the mounting holes can be matched with fixings to be connected to a hospital bed, the gaskets can enable the brackets 2 to be located on the ground for use, a hollow rod 3 is fixedly connected to the support plate 1, a fixing plate 4 is fixedly connected to the outer surface of the hollow rod 3, a front end surface of the fixing plate 4 is fixedly connected to a plurality of springs 5, a training plate 6 is fixedly connected to the plurality of springs 5, the springs 5 serve as elastic connecting parts between the training plate 6 and the fixing plate 4, and under the action of external force on the training plate 6, the training plate 6 can perform all-round tilting movement.
[0031] In this embodiment, a pair of support plates 1 and brackets 2 can form an I-shaped structure, which can be used horizontally or vertically, that is, on a hospital bed or on the ground.
[0032] A heel seat 7 for supporting the heel is fixedly connected to the training board 6, and a fixing part 1 for fixing the foot is provided on the heel seat 7. A massage board 8 is movably connected to the training board 6, and a fixing part 2 for fixing the foot is provided on the massage board 8.
[0033] The fixing part 1 includes a pair of binding belts 71, and the pair of binding belts 71 are provided with Velcro 1 that are bonded together. The fixing part 2 includes two pairs of binding belts 81, and each pair of binding belts 81 is provided with Velcro 2 that are bonded together.
[0034] In this embodiment, the user can fit the feet on the training board 6, with the heel seat 7 providing support for the heels, and provide the strap 1 71 and the strap 2 82 to fix the feet on the training board 6. The abdominal strap 1 71 can be wrapped around the ankles, and the abdominal strap 2 82 can be tied to the instep, and fixed with Velcro. In this way, the movement of the training board 6 can drive the feet to perform stable training movements.
[0035] Both sides of the massage board 8 are fixedly connected with insertion strips 16, and the massage board 8 is movably plugged into the training board 6 through the insertion strips 16. A massage protrusion 17 is provided on one side of the massage board 8. The training board 6 in this application is provided with a slot that is compatible with the massage board 8 and the insertion strips 16. This can meet the needs of flexible disassembly and assembly of the massage board 8, so as to facilitate the use of the massage protrusion 17 on the massage board 8 for corresponding massage on the soles of the feet.
[0036] A rotation drive unit 9 is provided on the bracket 1 and the hollow rod 3 , a rotating frame 10 is provided on the rotation drive unit 9 , a distance adjustment structure 11 is provided on the rotating frame 10 , and a magnetic drive module is provided on the distance adjustment structure 11 and the training board 6 .
[0037] The rotation drive unit 9 includes a motor 91 fixedly connected to the support plate 2, a gear 92 fixedly connected to the output end of the motor 91 and a tooth plate 93 meshingly connected to the gear 92. The tooth plate 93 is a circular structure. The tooth plate 93 is fixedly connected to the outer surface of the hollow rod 3. The rotating frame 10 is set on the tooth plate 93. In this application, the rotating frame 10 can be set on the tooth plate 93 by bolts, which can meet the convenience of disassembly of the rotating frame 10. The motor 91 drives the gear 92 to rotate, and the tooth plate 93 can rotate on the hollow rod 3, so that the distance adjustment structure 11 on the tooth plate 93 can rotate around the hollow rod 3.
[0038] The rotating frame 10 is arranged in an L-shaped structure, and the distance adjustment structure 11 includes a slide 111 slidably connected to the transverse section of the rotating frame 10, a fixed block 112 fixedly connected to the slide 111 and a butterfly bolt 113 threaded through the fixed block 112. One end of the butterfly bolt 113 arranged on the fixed block 112 is threadedly connected to the transverse section of the rotating frame 10. A plurality of fixing grooves for threaded connection of the butterfly bolt 113 are provided on the transverse section of the rotating frame 10. The slide 111 slides on the rotating frame 10 and is threadedly connected to one of the fixing grooves through the butterfly bolt 113. This makes it easy to adjust and lock the slide 111 at any position on the rotating frame 10 to meet the adjustability of the magnetic field position of the magnetic drive module.
[0039] The magnetic drive module includes a plurality of magnet blocks 13 fixedly embedded in the rear end surface of the training board 6 and an electromagnet 12 fixedly connected to the slide 111. The plurality of magnet blocks 13 are distributed in a ring at the rear end surface of the training board 6. When the electromagnet 12 is energized to generate magnetic force, the electromagnet 12 and the magnet block 13 magnetically repel each other. Since the slide 111 can be adjusted in position on the rotating frame 10, the distance between the electromagnet 12 and the magnet block 13 can be adjusted.
[0040] In this embodiment, when the gear plate 93 drives the rotating frame 10 to rotate, the energized electromagnet 12 can generate a repulsive force on the magnet block 13, and because the electromagnet 12 can move on a path surrounded by several magnet blocks 13, the electromagnet 12 sequentially interacts with the magnet blocks 13 through magnetic effects, so that the magnet block 13 can push the training board 6 in the area to move, and cooperate with the spring 5 that provides an elastic connection for the training board 6. In this way, the training board 6 can perform all-round floating and tilting in an orderly manner, so that the feet restrained on the training board 6 can perform multi-position foot pumping exercises, thereby promoting blood recovery and achieving the effect of semi-automatic exercise training, so that the feet can be trained to prevent and treat deep vein thrombosis of the lower limbs without the user applying force.
[0041] In addition, since the position of the electromagnet 12 can be adjusted through the distance adjustment structure 11, the magnetic field position of the electromagnet 12 and the magnet block 13 can be adjusted. For the purpose of adjusting the size of the magnetic field, the effect of the magnet block 13 on the training plate 6 can be changed, that is, the floating inclination rate of the training plate 6 can be changed, thereby meeting the adjustability of the posture training angle for lower limb deep vein thrombosis prevention and treatment training.
[0042] It is worth noting that, since the rotating frame 10 can be set on the tooth plate 93 by bolts, the electromagnet 12 can be removed by disassembling the rotating frame 10 on one side of the training board 6. In this way, the spring 5 is used alone to provide elastic support for the training board 6, and the training board 6 can also be used for foot training with manual intervention, that is, by applying force on the training board 6 by the foot to tilt and press it.
[0043] Example 2 The difference between this embodiment and embodiment 1 is that a cam 14 is rotatably connected to the inner side of one end of the hollow rod 3, the cam 14 is movably connected to the rear end surface of the training board 6, and a vibration driving structure 15 for driving the cam 14 to rotate is provided on the hollow rod 3.
[0044] The vibration drive structure 15 includes a motor 2 151 fixedly connected to the inside of the hollow rod 3 and a belt transmission mechanism 152 arranged on the motor 2 151. The motor 2 151 is connected to the cam 14 through the belt transmission mechanism 152. The belt transmission mechanism 152 is composed of a belt and a pulley.
[0045] In this embodiment, the cam 14 is driven to rotate by the motor 2 151 through the belt transmission mechanism 152, and the high-frequency contact between the protruding portion of the cam 14 and the training plate 6 is utilized, and the elastic connection provided by the spring 5 for the training plate 6 is achieved, so that the training plate 6 can achieve a vibration effect. At this time, the massage plate 8 can change the insertion direction so that the side with the massage protrusion 17 corresponds to the sole of the foot, and the foot is fixed by the strap 1 71 and the strap 2 81, so that the foot can be vibrated and massaged, thereby improving the training functionality and being more practical.
[0046] The bracket 2 is fixedly connected to an assembly seat 18, and a conductive slip ring 19 is fixedly passed through the assembly seat 18. The conductive slip ring 19 is located on the outside of the hollow rod 3. The conductive slip ring 19 is movably sleeved on the hollow rod 3. The position setting of the conductive slip ring 19 can provide a rotating power supply effect for the rotating electromagnet 12, thereby facilitating the control of the switch of the electromagnetic power supply of the electromagnet 12. The conductive slip ring 19 is an electrical accessory in the prior art, so it will not be further described here.
[0047] A telescopic rubber sleeve 20 is fixedly connected to the bracket 2, and one end of the telescopic rubber sleeve 20 is fixedly connected to a fixed plate 1 21, and a fixed plate 2 22 is fixedly connected to the peripheral side of the training board 6. The fixed plate 1 21 and the fixed plate 2 22 are connected by fasteners. The telescopic rubber sleeve 20 can be telescopically folded when it floats with the training board 6 so as to surround and protect the area between the training board 6 and the bracket 2. By surrounding the action structure area of the lower limb deep vein thrombosis prevention and treatment trainer of the present application, the safety of use can be improved. The fasteners on the fixed plate 1 21 and the fixed plate 2 22 can be bolts or other detachable structural parts. By giving the telescopic rubber sleeve 20 the ability to be detachable, so as to expose the working area between the training board 6 and the bracket 2, it is convenient to adjust the use position of the electromagnet 12 and the use position of the rotating frame 10.
