[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a rehabilitation exercise assistive device for preventing deep vein thrombosis in the lower extremities. Background Technology

[0002] There are two types of venous thrombosis: one is thrombophlebitis, which refers to inflammation as the initial symptom and thrombosis as a secondary process; the other is venous thrombosis, which refers to thrombosis as the initial symptom and inflammation of the vein wall as a secondary process, most commonly seen in the deep veins of the lower extremities. The elderly not only have a high incidence rate but are also prone to fatal pulmonary embolism, which deserves serious attention.

[0003] To prevent lower limb thrombosis in the elderly, preventive exercises can be performed in daily life, usually through massage. However, the elderly have difficulty bending over, and massaging the lower limbs can be very burdensome and carry certain risks. Therefore, we propose a rehabilitation exercise assistive device for preventing lower limb deep vein thrombosis. Utility Model Content

[0019] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0020] Example 1:

[0021] like Figures 1-3 As shown, a rehabilitation exercise aid for preventing deep vein thrombosis in the lower extremities includes a main body 1 and a massage mechanism. The massage mechanism includes an inner cavity 11, which is semi-open at the top of the main body 1. A foot pedal 2 is movably connected to the inner side of the inner cavity 11, and a spring assembly is provided between the foot pedal 2 and the bottom of the inner cavity 11. A movable groove 13 is provided inside the inner cavity 11. A first rack 22 is provided on the outer side of the foot pedal 2. One end of the first rack 22 is located inside the movable groove 13 and is meshed with a gear 23. A second rack 25 is meshed on the other side of the gear 23. A movable rod 26 is fixedly connected to the other side of the second rack 25. A receiving rod 27 is provided on the side of the movable rod 26 near the foot pedal 2. One end of the receiving rod 27 extends to the top of the foot pedal 2 and is movably connected to a massage stick 28. A connecting rotating rod 24 is provided inside the gear 23, and the connecting rotating rod 24 is connected to the movable groove 13 by a bearing.

[0022] There are two types of venous thrombosis: one is thrombophlebitis, which refers to inflammation as the initial symptom and thrombosis as a secondary process; the other is venous thrombosis, which refers to thrombosis as the initial symptom and inflammation of the vein wall as a secondary process, most commonly seen in the deep veins of the lower extremities. The elderly not only have a high incidence rate but are also prone to fatal pulmonary embolism, which deserves serious attention.

[0023] To prevent lower body thrombosis in the elderly, preventive measures can be taken in daily life, usually through massage. However, the elderly have difficulty bending over, and massaging the lower limbs can be very burdensome for them and also carries certain risks.

[0024] The elderly person sits down on a chair of suitable height, places their feet inside the inner groove 11, above the foot pedal 2, and then presses down on the foot pedal 2. The first rack 22 moves down with the foot pedal 2 and drives the gear 23 to rotate. When the gear 23 rotates, it drives the second rack 25 on the other side to rise. The movable rod 26 and the receiving rod 27 also rise. The massage stick 28 contacts the elderly person's lower limbs and moves with the movement of the receiving rod 27, thus completing the massage of the lower limbs. When the foot pedal 2 is pressed down, the spring assembly in the inner groove 11 is also compressed until the elderly person releases their force. The spring extends and drives the foot pedal 2 to rise again. The second rack 25 also moves in the opposite direction with the movable rod 26 and the receiving rod 27, thus massaging the lower limbs back and forth.

[0025] The massage stick 28 allows the elderly to control its height by stepping on it, thus enabling them to massage their lower limbs without bending over. This allows them to independently complete daily rehabilitation training related to thrombosis prevention. The device has a simple structure, is easy to operate, and is easy to use.

[0026] In other embodiments, this embodiment discloses, please refer to Figure 1 , Figure 2 As shown, the first rack 22 is mirror-shaped with the center point of the surface on one side of the foot pedal 2 as the axis. The number of gears 23, the second rack 25, the receiving rod 27, and the massage stick 28 are the same as the number of the first rack 22. Through this design, massage components can be added to improve the efficiency and intensity of massage.

[0027] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, a positioning groove 12 is provided on the inner side of the inner cavity groove 11, and a connecting slider 21 is provided on the outer side of the pedal 2. The connecting slider 21 is slidably connected to the inner side of the positioning groove 12. Through this design, when the pedal 2 is raised or lowered, the pedal 2 and the inner cavity groove 11 can maintain a certain tightness of connection, thereby improving the stability of raising and lowering.

[0028] In other embodiments, this embodiment discloses, please refer to Figure 1 As shown, a groove is provided on the top end face of the foot pedal 2, and an anti-slip pad is attached to the inside of the groove; this design makes it easier for the elderly to apply force when stepping on the foot pedal 2, and prevents slipping.

[0029] Example 2:

[0030] In other embodiments, this embodiment discloses, please refer to Figure 1 , Figure 4As shown, it also includes a connection mechanism, which includes a connection slot 14. The connection slot 14 is located on the outside of the device body 1. A first magnetic sheet 15 is provided on the inside of the connection slot 14. A connection rod 3 is movably inserted into the inside of the connection slot 14. A second magnetic sheet 31 is provided on one end face of the connection rod 3. The second magnetic sheet 31 and the first magnetic sheet 15 are magnetically connected. An auxiliary pull plate 32 is provided on one end of the connection rod 3 located on the outside of the device body 1. Anti-slip texture is provided on the outside of the auxiliary pull plate 32.

[0031] After aligning the connecting rod 3 with the connecting slot 14, push it in. The connecting rod 3 enters the bottom of the inner side of the connecting slot 14 and the second magnetic piece 31 and the first magnetic piece 15 are connected. This ensures that multiple device bodies 1 are joined together. At the same time, the connecting rod 3 can be operated by using the auxiliary pull plate 32. When multiple device bodies 1 are placed, they can be easily connected, thereby avoiding displacement during use and causing burden to the user, and improving the safety of use.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
