[0001] The utility model belongs to the medical auxiliary device technical field, concretely is a kind of adjustable gear's restless leg syndrome patient sickbed exercise bicycle. BACKGROUND

[0002] Restless leg syndrome in uremia, called in clinic as restless leg syndrome, is a common complication of uremia, and due to the almost lost function of kidney in discharging toxins and water, toxins and water gather in the body, erode nerves and muscles, cause nerve and muscle dysfunction, and further trigger restless leg syndrome.In addition, uremia often causes elevated parathyroid hormone levels, and deposition erodes nerve endings in the limbs, which is an important factor causing restless leg syndrome.The symptoms of restless leg syndrome mainly occur in both lower limbs, but can also involve the thighs and feet, with various painful sensations such as deep leg acid, numbness, pain, burning, crawling and itching.

[0003] In order to alleviate the pain of patients' legs caused by restless leg syndrome, a small pedal bicycle is currently placed on the sickbed to facilitate the patient to exercise the legs.The small pedal bicycle currently used is directly placed on the sickbed without limiting the position, resulting in poor stability of the pedal bicycle during use, and cannot provide a safe and stable exercise environment for the patient.In addition, the height of the small pedal bicycle is fixed and cannot be adjusted according to the patient's condition and height, reducing the applicability of the device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that the drawings are schematic and not illustrated to scale. For clarity and convenience, the relative sizes and proportions of the parts shown in the drawings have been exaggerated or reduced in size. Any size is only illustrative and not limiting.

[0026] As attached Figure 1 To be continued Figure 5 As shown:

[0027] Example 1: This utility model provides an adjustable-gear exercise bike for patients with restless legs syndrome, comprising:

[0028] The housing 1 has a rotating wheel 2 rotatably mounted inside the housing 1, and rotating pedals 3 rotatably mounted on both sides of the housing 1. One end of each rotating pedal 3 passes through the housing 1 and is fixedly connected to both ends of the rotating wheel 2.

[0029] The resistance adjustment mechanism 5 is installed inside the housing 1 to adjust the resistance of the rotating wheel 2;

[0030] The lifting mechanism 6 is installed at the rear end of the housing 1. The lifting mechanism 6 includes a lifting plate 61 fixedly installed at the rear end of the housing 1. A guide groove 62 is slidably connected to the outside of the lifting plate 61. A lead screw 63 is rotatably installed inside the guide groove 62. A threaded ring 64 is fixedly inserted inside the lifting plate 61. The threaded ring 64 is threadedly connected to the lead screw 63.

[0031] The fixing mechanism 7 is installed at the lower end of the guide groove 62. The fixing mechanism 7 includes a connecting rod 71 fixedly installed at the lower end of the guide groove 62, and both ends of the connecting rod 71 are provided with slots 72.

[0032] The fixing mechanism 7 also includes a screw 73 threadedly connected inside the slot 72, and a pressure ring 74 is fixedly installed at the front end of the screw 73.

[0033] The lifting mechanism 6 also includes a booster ring 65, and the upper end of the lead screw 63 extends through the guide groove 62, with the upper end of the guide groove 62 fixedly connected to the booster ring 65.

[0034] Both rotating pedals 3 have locking components 4 fixedly installed at the upper front part.

[0035] As can be seen from the above, during use, by placing the exercise bicycle on the hospital bed, the slots 72 at both ends of the connecting rod 71 engage with the bed rails, and rotating the screw 73 causes it to press against one side of the bed rails, thereby causing the pressing ring 74 to abut against one side of the bed rails, further securing the bicycle to the hospital bed. This avoids the problem of poor stability of the exercise bicycle when the patient is using it. Depending on the patient's condition and height, medical staff can rotate the assist ring 65 to drive the lead screw 63 to rotate, thereby causing the threaded ring 64 to mesh with the lead screw 63, further driving the lifting plate 61 to slide inside the guide groove 62, thus adjusting the height of the exercise bicycle. By engaging the slots 72 at both ends of the connecting rod 71 of the exercise bicycle with the bed rails, and further securing it with screws 73 and pressure rings 74, the stability of the exercise bicycle during use is ensured. This design avoids potential accidents caused by the bicycle wobbling or shifting during exercise, providing patients with a safe and stable exercise environment. Secondly, the height of the exercise bicycle can be adjusted through the lifting mechanism 6, allowing for personalized adjustments according to the needs of different patients. This ensures that each patient can exercise at the most suitable height, improving the comfort and effectiveness of the exercise and enhancing the adaptability of the device.

[0036] The patient places both feet on the rotating pedal 3, and the locking device 4 fixes the patient's feet to improve the stability of the patient's feet. By stepping on the rotating pedal 3, the patient can exercise their legs, reduce the pain level when restless legs syndrome occurs during treatment, and improve the patient's comfort.

[0037] Example 2: This is the second embodiment of the present invention, including:

[0038] The housing 1 has a rotating wheel 2 rotatably mounted inside the housing 1, and rotating pedals 3 rotatably mounted on both sides of the housing 1. One end of each rotating pedal 3 passes through the housing 1 and is fixedly connected to both ends of the rotating wheel 2.

[0039] The resistance adjustment mechanism 5 is installed inside the housing 1 to adjust the resistance of the rotating wheel 2.

[0040] The resistance adjustment mechanism 5 includes a fixed frame 51 fixedly installed inside the lower end of the housing 1, a rotating shaft 52 rotatably installed inside the fixed frame 51, and a friction pad 53 fixedly installed on the outer surface of the rotating shaft 52.

[0041] A connecting plate 54 is fixedly installed on the upper end of the friction pad 53, and a support frame 55 is fixedly installed on the lower end of the housing 1. An electric push rod 56 and a guide rod 57 are fixedly installed on the upper end of the support frame 55. The output end of the electric push rod 56 is fixedly connected to the lower end of the connecting plate 54, and the connecting plate 54 is slidably connected to the guide rod 57.

[0042] As can be seen from the above, during use, the PLC controller controls the extent of the electric push rod 56 to push the connecting plate 54 up or down, which in turn drives the friction pad 53 to rotate within the fixed frame 51 under the action of the rotating shaft 52. This adjusts the degree of pressure between the friction pad 53 and the rotating wheel 2, further adjusting the resistance of the rotating wheel 2, and subsequently adjusting the resistance of the exercise bicycle, thereby achieving different levels of exercise for both legs. The PLC controller can adjust the extent of the electric push rod 56 as needed without manual intervention, improving the automation level of the equipment. By adjusting the different resistances of the rotating wheel 2, it can adapt to different patients, thereby reducing the pain level of patients experiencing restless legs syndrome during treatment and improving patient comfort.
