Description

Technical Field

[0001] The utility model relates to the technical field of lower limb exercise devices, and more specifically to a portable exercise device for preventing lower limb thrombosis. Background Art

[0002] Lower limb thrombosis is a very dangerous symptom. There are many reasons for lower limb thrombosis. Long-term immobility and slow blood flow are one of the causes of thrombosis. Proper exercise can prevent lower limb thrombosis. The prevention of lower limb thrombosis mainly includes limb activity exercises, promoting blood circulation, preventing blood stasis, and drug prevention. Currently commonly used drugs include oral drugs, intravenous or intramuscular drugs, such as low molecular weight heparin.

[0003] Chinese Patent Authorization Announcement No.: CN215962032U provides an exercise device for preventing lower limb thrombosis. The solution provides a seat cushion support for the user by setting a support base, and setting a telescopic rod and a seat on the upper side of the support base. The telescopic rod and the slide rail mechanism can be adjusted in direction, and the whole has a flexible adjustment effect. By setting two foot pedals, and setting a linkage mechanism and a power mechanism matching the two foot pedals, the effect of actively controlling the two foot pedals to make circular motion is achieved, which can provide the user with foot exercise and promote blood circulation in the lower limbs. By setting a rotating plate on the foot pedal and setting an adjusting bolt of the adjustable rotating plate, the effect of bending and stretching the sole of the user's foot can be achieved, and the effect of foot massage can be achieved in combination with the effect of the foot pedal rotation.

[0004] However, in this solution, the patient must move to the cushion before exercising. For some patients with mobility impairments or those who are older, moving to the cushion is troublesome and there is a risk of falling when getting on and off the cushion. Therefore, a portable exercise device for preventing lower limb thrombosis is proposed to address the above problem. Utility Model Content

[0031] Lower limb thrombosis is a very dangerous symptom. There are many reasons for lower limb thrombosis. Long-term immobility and slow blood flow are one of the causes of thrombosis. Proper exercise can prevent lower limb thrombosis. The prevention of lower limb thrombosis mainly includes limb activity exercises to promote blood circulation and prevent blood stasis. Considering that some patients have inconvenient legs and feet or are older, it is inconvenient for them to move to exercise equipment. Therefore, in this solution, the device is small as a whole, and the user can place the device as a whole in front of the sofa or wheelchair where the patient is, so that the patient can use the device for exercise without moving. The patient can place both feet on a pair of foot pedals 403, and then step down on one of the foot pedals 403. The foot pedal 403 moves in the movable hole and drives the limit block 402 on the mounting bracket 401. When the limit block 402 moves, it will squeeze the spring 404 and receive the reaction force of the spring 404, thereby providing a certain resistance for the patient's leg movement and improving the exercise effect. When the limit block 402 moves, it drives the rack 405 to move, and the rack 405 drives the gear 406 to rotate, thereby driving another rack 405, the limit block 402 and the foot pedal 403 to move in opposite directions. As a result, the patient's feet can move up and down respectively, and the exercise process can be carried out smoothly. At the same time, the inner cavity of the shell 1 is equipped with a sensor, which can detect the movement trajectory of a pair of limit blocks 402, and upload the number of movements to the counter 2 for display, so that the patient can intuitively grasp the degree of exercise. The above-mentioned monitoring principle of the sensor is the existing technology and will not be elaborated here.

[0032] See also Figure 2The top of the base 301 is fixedly connected to a limiting tube 302, the inner wall of the limiting tube 302 is slidably connected to an extension rod 303, the top of the extension rod 303 is rotatably connected to a movable block 305, the movable block 305 is slidably connected to the bottom end of the shell 1, and the limiting tube 302 is threadedly connected to a screw 304, which extends to the inner cavity of the limiting tube 302 and abuts against the extension rod 303.

[0033] In this solution, the user can rotate the screw rod 304 to make the screw rod 304 move outward on the limiting tube 302, so that the screw rod 304 is separated from the extension rod 303. Then the user can pull the extension rod 303 upward or downward. During the movement, the extension rod 303 drives the movable block 305 to rotate, and makes the movable block 305 slide at the bottom end of the shell 1, and at the same time drives the shell 1 to rotate on the base 301, so as to adjust the inclination angle of the shell 1, so that the angle of the device can be adjusted according to the patient's needs, effectively improving the patient's usage experience.

[0034] Working principle:

[0035] When in use, the user places the entire device in front of the sofa or wheelchair where the patient is located, and the patient places both feet on a pair of foot pedals 403, and then steps down on one of the foot pedals 403, the foot pedal 403 moves in the movable hole and drives the limit block 402 to slide on the mounting bracket 401, and the limit block 402 squeezes the spring 404 while moving and is subjected to the reaction force of the spring 404, thereby providing a certain resistance for the patient's leg movement, and the limit block 402 drives the rack 405 to move when it moves, and the rack 405 drives the gear 406 to rotate, thereby driving the other rack 405, the limit block 402 and the foot pedal 403 to move in opposite directions, so that the patient's feet can move back and forth up and down respectively, and the exercise process can be carried out smoothly, and the sensor installed in the inner cavity of the shell 1 can detect The movement trajectory of a pair of limit blocks 402 is measured, and the number of movements is uploaded to the counter 2 for display, so that the patient can intuitively grasp the degree of exercise. The user can rotate the screw rod 304 to make the screw rod 304 move outward on the limit tube 302, so that the screw rod 304 is separated from the extension rod 303, and then the user can pull the extension rod 303 upward or downward. The extension rod 303 drives the movable block 305 to rotate during the movement, and makes the movable block 305 slide at the bottom end of the shell 1, and at the same time drives the shell 1 to rotate on the base 301, so as to adjust the inclination angle of the shell 1. After adjusting to the appropriate angle, the screw rod 304 is rotated in the opposite direction to make the screw rod 304 abut against the extension rod 303 again, so as to fix the extension rod 303, so that the angle of the device can be adjusted according to the patient's needs.

[0036] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
