Description

Technical Field

[0001] This utility model relates to the field of medical assistive device technology, and in particular to an exercise device for preventing lower limb thrombosis. Background Technology

[0002] After surgery, some patients need to rest in bed for a period of time. However, prolonged lying down can reduce the number of muscle contractions in the lower limbs, resulting in slow deep venous return and making it easier for blood to accumulate and form thrombi. Once thrombi form, blood will accumulate at the blocked site, causing lower limb congestion and leading to edema and other adverse conditions. To avoid the formation of thrombi, patients are often given passive lower limb exercises, such as ankle pump exercises, quadriceps pump exercises, knee flexion and extension exercises in a supine position, and limb elevation.

[0003] However, in actual use, there are two common ways to elevate the lower limbs. One method is to add a thick pad to the lower leg, so that the ankle is in a higher position and the lower leg is in a lower position. This can effectively prevent blood blockage and accumulation. The thick pad is usually made of soft material, which can improve the patient's comfort when using it. However, after a period of use, the thick pad will become concave in the middle where it is compressed. And with continuous use, the concave area is difficult to return to its original shape. As a result, the elevation effect will be greatly reduced when using it again. In addition, the thick pad is relatively soft, and multiple pads stacked together can also make the force point unstable. This can easily cause the patient's lower leg to deviate after being raised or even fall directly onto the hospital bed, affecting the normal recovery of the patient's lower limbs.

[0004] Therefore, this application provides an exercise device for preventing lower extremity thrombosis to meet the needs. Utility Model Content

[0005] The technical problem this invention aims to solve is to provide an exercise device for preventing lower limb thrombosis. This addresses the issue that in existing lower limb elevation methods, after a period of use, the thick pad develops a depression in the middle due to compression, and this depression is difficult to restore to its original shape with continued use. Consequently, the elevation effect diminishes significantly with continued use. Furthermore, the thick pad is relatively soft, and stacking multiple pads together can cause instability in the pressure point, easily leading to displacement of the patient's lower leg after elevation or even the patient falling directly onto the bed, thus affecting the normal recovery of the patient's lower limb.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An exercise device for preventing lower limb thrombosis includes a leg-relaxing pad, a placement part fixedly connected to the middle of the leg-relaxing pad, an operating part fixedly connected to the inner cavity of the leg-relaxing pad, a traction rope installed in the middle of the operating part, and a handle buckle installed on the outer side wall of the leg-relaxing pad.

[0008] An auxiliary exercise component is provided to assist patients in exercising their calves. The auxiliary exercise component is connected to the leg-comforting mat and the working unit.

[0009] Optionally, the auxiliary exercise component includes a spring sheet fixedly connected to the inner wall of the working part, a first movable column is attached to the outer surface of the spring sheet, a second movable column is fixedly connected to the top of the first movable column, a first transition ring is sleeved at the middle position of the outer side of the second movable column, and a second transition ring is sleeved at the middle position of the outer side of the first movable column.

[0010] Optionally, a first support block and a second support block are symmetrically installed on the outer wall of the bottom of the first movable column, and a baffle plate is fixedly connected to the inner cavity of the working part.

[0011] Optionally, a main frame is installed at the connection between the placement part and the leg-comforting pad, a secondary frame is fixedly connected to one side of the main frame, and a force-bearing pad is fixedly connected to the outer surface of the main frame.

[0012] Optionally, a third transition ring is fitted on the outer surface of the traction rope near the working part, a limiting ring is fitted on the outer surface of the traction rope near the third transition ring, and a hand pull plate is fixedly connected to the end of the traction rope away from the working part.

[0013] Optionally, the spring is made of elastic material, and one end is fixedly connected to the side wall of the inner cavity of the working part, and the other end is fixedly connected to the outer surface of the second transition ring. The diameter of the first moving column is smaller than the diameter of the second moving column. A rotating column is provided at the bottom end of the first moving column. The rotating column is fixed to the side of the inner cavity of the leg-comforting pad. The inner circumference of the first transition ring is sleeved on the outer circumference surface of the second moving column. The outer circumference of the first transition ring is slidably connected to the bottom end of the force-bearing pad.

[0014] Optionally, the first support block and the second support block have the same size and structure, and are both fixedly connected to the bottom of the first moving column and located on both sides of the rotating column. The outer surface of the enclosure plate is fixedly connected to the inner cavity of the working part, and the size of the enclosure plate is adapted to the size of the inner cavity of the working part.

[0015] Optionally, both the main frame and the secondary frame are made of rigid material, and the force-bearing pad includes two parts, one part of flexible material and the other part of rigid material, with the flexible material force-bearing pad located below the rigid material force-bearing pad.

[0016] Optionally, the traction rope comprises two parts, wherein the diameter of the traction rope inside the placement part is larger than the diameter of the traction rope outside the placement part.

[0017] Optionally, the third transition ring is fixedly connected to the middle of the side wall of the working part, the limiting ring is fixedly connected to the middle of the outer wall of the placement part, and the side of the hand pull plate is fixedly connected to the end of the traction rope.

[0018] Compared with the prior art, this utility model has at least the following beneficial effects:

[0019] In the above-mentioned solution, the auxiliary exercise component allows the patient's lower leg to be effectively placed on it, and during movement and shaking, the lower leg will not fall off the leg support mat due to excessive amplitude. At the same time, after placing the lower leg on it, the patient can also perform small-range exercises on the lower leg using the strength of their hands. In this way, both the hands and legs can be exercised well, thereby improving the patient's leg exercise and recovery ability. This also demonstrates the effect of the auxiliary exercise component on the patient's leg recovery during exercise, ensuring the normal recovery of the lower limbs while the patient is lying in bed.

[0020] By setting up a first moving column, a second moving column, a first transition ring, and a hand-pulling plate, after the exercise, the second moving column and the first transition ring are on the left side, while the patient still holds the traction rope and continues to pull. Then, the patient slightly retracts their lower leg so that the calf does not touch the pressure pad, and gently releases the main power of the hand-pulling plate. The spring will rebound due to the lack of compression, thereby driving the first and second moving columns to return to their original positions. After repeating the above actions, the patient's lower leg can be continuously exercised. In addition, a first support block and a second support block are set up to ensure that the first moving column, the second moving column, and the first transition ring have a maximum turning angle when rotating to both sides, which increases the turning ability and improves the practicality of the device. It can also exercise the patient's upper limbs and arms while exercising the patient's legs, improving the patient's overall body coordination. Attached Figure Description

[0037] like Figure 1 and Figure 2As shown, an embodiment of this utility model provides an exercise device for preventing lower limb thrombosis, including a leg-comforting pad 1, a placement part 2 is provided between two opposing leg-comforting pads 1, that is, the placement part 2 is fixedly connected to the middle of the leg-comforting pad 1, and an operating part 3 is fixedly connected to the inner cavity of the leg-comforting pad 1. A traction rope 4 is installed in the middle of the operating part 3 and extends to the outside of the placement part 2. The leg-comforting pad 1 has a handle 5 installed on its outer wall; an auxiliary exercise component is used to assist the patient in exercising their lower legs. The auxiliary exercise component is connected to the leg-comforting pad 1 and the working part 3. The leg-comforting pad 1 is made of silicone, which provides overall stability and a comfortable feel. The leg-comforting pad 1 is divided into two parts. The placement part 2 is made of flexible material and has a certain pulling force. It is fixed in the middle of the leg-comforting pad 1, which serves to connect the two leg-comforting pads 1 and to place the patient's lower legs. The working part 3 is made of plastic and is fixed to the side of the inner cavity of the leg-comforting pad 1. One end of the traction rope 4 passes through the middle of the side of the working part 3. The handle 5 is located on the outer wall of the leg-comforting pad 1.

[0038] The auxiliary exercise component allows the patient's lower leg to be effectively placed on the placement part 2, and during movement and shaking, the lower leg will not fall off the leg-relaxing pad 1 due to excessive amplitude. After placing the lower leg on the pad, the patient can also perform small-range exercises using their hand strength. This allows both the hand and leg to receive good exercise, thereby improving the patient's leg exercise and recovery ability. It also demonstrates the effect of the auxiliary exercise component on the patient's leg recovery during exercise, ensuring the patient's normal recovery of the lower limbs while lying in bed.

[0039] like Figures 3 to 6 As shown, a main frame 201 is installed at the connection between the placement part 2 and the leg-comforting pad 1. A secondary frame 202 is fixedly connected to one side of the main frame 201. A force-bearing pad 203 is fixedly connected to the surface of the main frame 201. Both the main frame 201 and the secondary frame 202 are made of rigid material. The main frame 201 is fixed at the connection between the leg-comforting pad 1 and the placement part 2 and is symmetrically distributed on both sides of the placement part 2. Several secondary frames 202 are fixed on one side of the main frame 201 along the extension direction of the main frame 201. The spacing between the secondary frames 202 is not the same and has uncertain factors. The specific distribution depends on the actual force on the leg on the placement part 2. The force-bearing pad 203 is fixed at the bottom of the surface of the placement part 2, and there are two of them. One is fixed at the lower end of the outer surface of the main frame 201, and the other is fixed at the upper end of the outer surface of the main frame 201. The force-bearing pad 203 at the lower end is made of flexible material, and the force-bearing pad 203 at the upper end is made of rigid material.

[0040] Through the above structure, the main frame 201 and the support pad 203 can be used to plasticize and fix the placement part 2 as a whole, so that when the patient's lower leg is placed on the surface of the placement part 2, it can have a good support position. In conjunction with the use of the leg-relaxing pad 1, when the patient places his lower leg on the surface of the placement part 2, the lower leg will not fall off the leg-relaxing pad 1 and the placement part 2 due to the swaying or displacement of the patient's lower leg. At the same time, the support pad 203 at the lower end is located at the calf of the patient's lower leg and can support the calf, while the support pad 203 at the upper end can support the patient's heel. In this state, the patient's lower leg can be well supported, reducing the overall support force on the leg and improving comfort. Furthermore, the patient's swaying or displacement will not cause the lower leg to fall off. The material of the placement part 2 is flexible, which can also support the lower leg well, thereby effectively ensuring the exercise and stability of the patient's lower leg position.

[0041] like Figures 4 to 7As shown, the auxiliary exercise component includes a spring piece 301 fixedly connected to the side of the inner cavity of the working part 3. A first moving column 302 is attached to the outer surface of the spring piece 301. A second moving column 303 is fixedly connected to the top of the first moving column 302. A first transition ring 304 is fixedly connected to the middle position of the outer side of the second moving column 303. A second transition ring 305 is sleeved at the middle position of the outer side of the first moving column 302. A first support block 306 and a second support block 307 are symmetrically installed on the outer wall of the bottom of the first moving column 302. A baffle plate 308 is fixedly connected to the inner cavity of the working part 3. A third transition ring 401 is fixedly connected to the traction rope 4 near the outer surface of the working part 3. A limit ring 402 is fixedly connected to the outer surface of the traction rope 4 near the third transition ring 401. A hand pull plate 403 is fixedly connected to the end of the traction rope 4 away from the working part 3. The spring 301 is made of elastic material, with one end fixed to the inner wall of the working part 3. The diameter of the first moving column 302 is smaller than the diameter of the second moving column 303. A rotating column is provided at the bottom end of the first moving column 302. The rotating column is close to the side of the inner cavity of the leg-comforting pad 1 and fixed inside the leg-comforting pad 1. The outer surface of the middle part of the first moving column 302 is fixed to the end of the traction rope 4. The first transition ring 304 is fixed to the middle part of the outer surface of the second moving column 303, and its structure is similar to that of an existing bearing. Its inner circumference is fixed to the middle part of the outer surface of the second moving column 303, and its outer circumference is slidably connected to the bottom end of the force-bearing pad 203. The second transition ring 305 is fixed on the first moving column 302 and above the rotating column, and the outer surface of the second transition ring 305 is fixed to the other end of the spring 301. The first support block 306 and the second support block 307 are made of the same material and have the same size, and are hollowed out in the middle. They are fixed to the bottom of the first moving column 302 on both sides of the rotating column. The baffle plate 308 is fixed in the inner cavity of the working part 3, and the size of the baffle plate 308 is the same as the size of the inner cavity of the working part 3. The inner cavity of the third transition ring 401 is sleeved on the traction rope 4 near one end of the first moving column 302, and the outer surface of the third transition ring 401 is fixed on the side wall of the working part 3. The inner cavity of the limiting ring 402 is sleeved on the outer surface of the traction rope 4, and the outer surface of the limiting ring 402 is fixed in the outer wall of the placement part 2. The side of the pull plate 403 is fixedly connected to the end of the traction rope 4 away from the first moving column 302. Several lightweight grooves are opened on the pull plate 403.

[0042] With the above structure, in the initial state, the first moving post 302 and the second moving post 303 are positioned on one side as shown. Figure 4As shown, at this time, the first transition ring 304 will not contact the bottom end of the pressure pad 203. When the patient's lower leg is placed on the surface of the pressure pad 203, the pressure pad 203 will move downward due to the weight of the lower leg. During the movement, the bottom end of the pressure pad 203 will abut against the surface of the first transition ring 304. At this time, after the patient places their lower leg on the placement part 2, they should maintain a corresponding supine or semi-supine position, hold the left and right hand pull plates 403 respectively, and start pulling outward. When pulling the hand pull plates 403, it will drive the movement of the traction rope 4. The traction rope 4 is fixed to the outer surface of the first moving column 302, so at this time the first moving column 302 will turn from one side to the other side, as shown. Figure 4 It can be seen that the movement trajectory is a rotation from right to left. During the rotation, the first transition ring 304 will have a maximum arc range of motion, which is the maximum diameter distance that the first transition ring 304 can form. At this time, the first transition ring 304, fixed to the outer surface of the middle part of the second moving column 303, will contact the bottom end of the pressure pad 203. With the patient's lower leg pressing down on the pressure pad 203, the first transition ring 304 can more easily contact the bottom end of the pressure pad 203, thus forming an interaction. Under the patient's continuous pulling action, the first transition ring 304 will turn from one side to the other side. This state will cause the pressure pad 203 to be squeezed by the first transition ring 304 and rise upward. The lifting will cause the patient's lower leg to rise simultaneously, completing one exercise. After the exercise, the second moving column 303 and the first transition ring 304 are in the same initial state on the other side. Figure 4 As shown, the patient continues to pull on the traction rope 4 while holding it. Then, the patient slightly retracts their lower leg so that the calf does not touch the pressure pad 203. The patient then gently releases the hand-pulling plate 403. The spring 301 will rebound due to the absence of pressure, thereby causing the first moving column 302 and the second moving column 303 to return to their original positions. The above actions are repeated to continuously exercise the patient's lower leg. To prevent the patient's hands from moving inconsistently when pulling the hand-pulling plate 403, a first support block 306 and a second support block 307 are also provided. This ensures that the first moving column 302, the second moving column 303, and the first transition ring 304 have a maximum turning angle when rotating to both sides, increasing the turning ability and improving the practicality of the device. It can also exercise the patient's upper limbs and arms while exercising the patient's legs, improving the patient's overall body coordination.

[0043] The workflow of the technical solution provided by this utility model is as follows:

[0044] When in use, the entire device is made of lightweight material, so it is easy to move. The leg cushion 1 can be moved as a whole by holding it by the handle 5.

[0045] The main frame 201 and the support pad 203 can be used to shape and fix the placement part 2 as a whole, so that when the patient's lower leg is placed on the surface of the placement part 2, it can have a good support position. When used with the leg-comforting pad 1, when the patient places his lower leg on the surface of the placement part 2, the lower leg will not fall off the leg-comforting pad 1 and the placement part 2 due to the swaying or displacement of the patient's lower leg. At the same time, the support pad 203, which is located at the lower end, is positioned at the calf of the patient's lower leg and can support it, while the support pad 203, which is located at the upper end, can support the patient's heel. In this state, the patient's lower leg can be well supported, reducing the overall support force on the leg and improving comfort. The patient's swaying or displacement will not cause the lower leg to fall off. The placement part 2 is made of flexible material, which can also support the lower leg well, thereby effectively ensuring the exercise and stability of the patient's lower leg position.

[0046] Initially, the first moving column 302 and the second moving column 303 are on one side; in this design, they are on the right side. Figure 4 As shown, at this time, the first transition ring 304 will not contact the bottom end of the pressure pad 203. When the patient's lower leg is placed on the surface of the pressure pad 203, the pressure pad 203 will move downward due to the weight of the lower leg. During the movement, the bottom end of the pressure pad 203 will abut against the surface of the first transition ring 304. At this time, after the patient places their lower leg on the placement part 2, they should maintain a corresponding supine or semi-supine position, hold the left and right hand pull plates 403 respectively, and start pulling outward. When pulling the hand pull plates 403, it will drive the movement of the traction rope 4. The traction rope 4 is fixed to the outer surface of the first moving column 302, so at this time the first moving column 302 will turn from one side to the other side, as shown. Figure 4 It can be seen that the movement trajectory is a rotation from right to left. During the rotation, the first transition ring 304 will have a maximum arc range of motion, which is the maximum diameter distance that the first transition ring 304 can form. At this time, the first transition ring 304, fixed on the outer surface of the middle part of the second moving column 303, will contact the bottom end of the pressure pad 203. With the patient's lower leg pressing down on the pressure pad 203, the first transition ring 304 can more easily contact the bottom end of the pressure pad 203, thus forming an interaction. Under the patient's continuous pulling action, the first transition ring 304 will turn from one side to the other side. This state will cause the pressure pad 203 to be squeezed by the first transition ring 304 and rise upward. The rising will cause the patient's lower leg to rise simultaneously, completing one exercise. After the exercise, the second moving column 303 and the first transition ring 304 are on the other side of the initial state. In this scheme, the left side is as follows. Figure 4As shown, the patient continues to pull on the traction rope 4 while holding it. Then, the patient slightly retracts their lower leg so that the calf does not touch the pressure pad 203. The main power of the pull plate 403 is released, and the spring 301 will rebound due to the absence of pressure, thereby causing the first moving column 302 and the second moving column 303 to return to their original positions. The above actions are repeated to continuously exercise the patient's lower leg. To prevent the patient's hands from moving inconsistently when pulling the pull plate 403, the first support block 306 and the second support block 307 are set to ensure that the first moving column 302, the second moving column 303 and the first transition ring 304 have a maximum turning angle when rotating to both sides, improving the practicality of the device. It can also exercise the patient's upper limbs and arms while exercising the patient's legs, improving the patient's overall body coordination.
