Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a training exercise device for preventing lower limb venous thrombosis. Background Art

[0002] Leg vein thrombosis is a common vascular disease that involves abnormal clotting of blood in the deep veins of the body, especially in the leg veins. People who sit or lie in bed for long periods of time, those after surgery, cancer patients, long-distance travelers, and those with certain genetic predispositions are at high risk of leg vein thrombosis. Leg vein thrombosis may not only cause local symptoms such as leg pain and swelling, but may also cause serious complications such as pulmonary embolism, a potentially fatal condition.

[0003] Lower limb venous thrombosis can cause blood to accumulate in the lower limb veins, causing swelling and pain in the legs. This pain and swelling will gradually increase as the condition worsens, seriously affecting the patient's daily life and work. Secondly, due to the formation of venous thrombosis, blood does not flow smoothly in the lower limb veins, which may cause local skin temperature to rise. This phenomenon of increased skin temperature is usually an obvious sign of venous thrombosis and requires timely medical treatment. It can also cause blood reflux to be blocked. Venous thrombosis will hinder the normal return of blood and cause blood to accumulate in the lower limb veins. This will not only aggravate swelling and pain, but may also lead to consequences such as varicose veins in the lower limbs. Based on the above problems, this application document proposes a training exercise device for preventing lower limb venous thrombosis. Utility Model Content

[0025] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0026] like Figures 1 to 4As shown, a training exercise instrument for preventing lower limb venous thrombosis includes a base plate 10, a motor 11 is fixed at one end of the base plate 10, a driving gear 12 is fixed at the output end of the motor 11, a support plate 14 is fixed at the upper end of the base plate 10 and at one end of the driving gear 12, a driven gear 13 is rotatably connected to the upper end of the support plate 14, and the driving gear 12 is meshed with the driven gear 13, first connecting rods 15 are fixedly connected to both sides of the driven gear 13, a second connecting rod 16 is rotatably connected to the top of the first connecting rod 15, a third connecting rod 17 is rotatably connected to the top of the second connecting rod 16, and the positions of the second connecting rods 16 on both sides being rotatably connected to the third connecting rod 17 are different, an end of the third connecting rod 17 away from the second connecting rod 16 is rotatably connected to a slider 18, a plurality of support rods 19 are fixed to the end of the base plate 10 away from the driving gear 12, wherein one support rod 19 is slidably connected to the slider 18, and a pedal 20 is fixed to the upper end of the third connecting rod 17.

[0027] Furthermore, the cross-sectional shape of the third connecting rod 17 is T-shaped, the cross-sectional shape of the slider 18 is I-shaped, and the slider 18 is adapted to the strut 19. The adaptation of the slider 18 and the strut 19 can increase the stability of the structure, especially when bearing loads, and can better disperse the pressure, reduce deformation and wear. At the same time, the slider 18 can reduce friction and wear, which helps to extend the service life of the lower limb venous thrombosis training exercise device and reduce maintenance costs.

[0028] Furthermore, a retaining ring 21 is rotatably connected to the upper end of the foot pedal 20. The retaining ring 21 serves as a stopper for the foot pedal 20, which helps to maintain the stability of the foot on the foot pedal 20 and improve safety.

[0029] Furthermore, the material of the retaining ring 21 is a flexible material, and the outer side of the retaining ring 21 is provided with anti-slip grooves. The flexible material can withstand a certain degree of deformation without breaking due to its bendable, foldable and stretchable properties. At the same time, the use of flexible materials can provide a better experience because they can fit the curve of the human body and reduce discomfort.

[0030] like Figures 4 to 6 As shown, a fixing rod 25 is fixed to the upper ends of two adjacent support rods 19 , and a telescopic rod 26 is slidably connected to the fixing rod 25 . A footrest 30 is fixed to the upper end of the telescopic rod 26 , and a rotating ring 27 is threadedly connected to one end of the fixing rod 25 .

[0031] Furthermore, a through hole is provided at the bottom of the footrest 30, and evenly distributed cross bars 31 are fixed on both sides of the through hole. Balls 32 are rotatably connected to the outer sides of the cross bars 31. The balls 32 can effectively stimulate the muscles and help relieve muscle tension and fatigue. At the same time, it can increase blood circulation in the calves, help to remove waste and metabolic products, and provide more oxygen and nutrients to the muscles.

[0032] Furthermore, an anti-skid rubber sleeve is sleeved on the outer side of the rotating ring 27, and a plurality of anti-skid grooves are evenly arranged on the outer side of the anti-skid rubber sleeve. The design of the anti-skid grooves increases the friction between the hand and the surface of the hand, thereby providing a better anti-skid effect.

[0033] The working principle of the utility model is:

[0034] When the motor 11 fixed at one end of the base plate 10 starts to rotate, the motor 11 drives the driving gear 12 to start rotating. Because the driving gear 12 is meshed and connected with the driven gear 13, and the driven gear 13 is rotatably connected to the support plate 14, the driven gear 13 starts to rotate. Because the first connecting rod 15 is fixedly connected to both sides of the driven gear 13, the first connecting rod 15 starts to rotate, and the top end of the first connecting rod 15 is rotatably connected to the second connecting rod 16. When the first connecting rod 15 starts to rotate, the second connecting rod 16 also starts to rotate. Because the top end of the second connecting rod 16 is rotatably connected to the third connecting rod 17, and the positions of the second connecting rods 16 on both sides are different, when the second connecting rod 16 rotates, the third connecting rod 17 starts to rotate. The bottom end of the third connecting rod 17 is rotatably connected to the slider 18, and the slider 18 is slidably connected in a support rod 19. When the third connecting rod 17 rotates, the slider 18 is pulled to make a linear sliding motion in the support rod 19. A footrest 20 is fixed to the support rod 19, and a retaining ring 21 is fixed to the upper end of the footrest 20. When the third connecting rod 17 rotates, the footrest 20 also rotates. When the foot is placed on the footrest 20 and fixed by the retaining ring 21, the foot starts to move the ankle joint under the rotation of the third connecting rod 17. At the same time, a fixing rod 25 is fixed to the upper end of the support rod 19, and the fixing rod 25 is slidably connected to the telescopic rod 26. A footrest 30 is fixed to the upper end of the telescopic rod 26. One end of the fixing rod 25 is threadedly connected to a rotating circular rod. Ring 27, when the height of the footrest 30 needs to be adjusted, the ring 27 can be rotated to adjust the height of the footrest 30, which can adapt to different people. At the same time, a through hole is opened at the bottom of the footrest 30, and evenly distributed cross bars 31 are fixed on both sides of the through hole. The outer side of the cross bar 31 is rotatably connected with a ball 32. When the foot moves the ankle joint, the ball 32 on the footrest 30 can press the outer side of the calf, thereby activating the leg muscles, improving the blood circulation of the lower limbs, and preventing the formation of venous thrombosis in the lower limbs.

[0035] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
