Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training equipment, in particular to a bed-based rehabilitation foot pedal rehabilitation device. Background Art

[0002] Patients who are bedridden for extended periods are prone to complications such as muscle atrophy and venous thrombosis. To prevent these complications, bed-based rehabilitation therapy is required. This typically involves encouraging patients to exercise in bed and using rehabilitation equipment to prevent muscle atrophy and joint stiffness. Elderly patients, particularly those with deteriorating blood flow, are more susceptible to these problems. Therefore, appropriate limb muscle exercises are essential for bedridden elderly patients, and pedal rehabilitation devices are often used to assist with these rehabilitation training.

[0003] The currently used bed-based rehabilitation foot pedal rehabilitation devices are mostly installed at the end of the bed, but except for the folding part, the rest of the structure is relatively fixed. There is no way to make corresponding adjustments according to the patient's height and body shape. It is difficult to achieve the best treatment effect of the device when used on patients with unsuitable height and body shape. For this reason, a bed-based rehabilitation foot pedal rehabilitation device is provided. Utility Model Content

[0023] like Figure 1-6As shown, a bed rehabilitation foot pedal rehabilitation device includes a bed frame 1, which is characterized in that baffles 2 are fixedly connected to the front and rear sides of the bed frame 1, a fixing component 3 is installed on the surface of the rear baffle 2, and a connecting plate 4 is connected to the fixing component 3 close to the side of the bed frame 1, and an extension column 5 is fixedly connected at the center of the outer surface of the connecting plate 4, and the extended end of the extension column 5 is fixedly connected to the connecting frame 6, and an adjustment component 7 is passed through and rotatably connected to the interior of the connecting frame 6, and a pedal 9 is fixedly connected to the end of the adjustment component 7. The device is installed on the baffle 2 by adjusting the threaded rod 305 inside the fixing component 3, and then the length of the sliding rod 1 702 and the sliding rod 2 705 is extended and retracted according to the patient's body shape to make the device more fit the natural leg spacing and leg length of the patient. After adjusting to the appropriate position, the screw and nut 707 are passed through and tightened to fix the state of the device, and then the patient can step on the pedal 9 for rehabilitation training.

[0024] like Figure 2 、 3 As shown, in some embodiments, the adjustment component 7 includes a rotating rod 701, the interior of the connecting frame 6 passes through and is rotatably connected to the rotating rod 701, the outer surface of the rotating rod 701 is fixedly connected to the roller 8, the interior of both ends of the rotating rod 701 is slidably connected to a sliding rod 1 702, the interior of the sliding rod 1 702 is arrayed and penetrated by a number of through holes 1 703, the interior of the rotating rod 701 passes through a through hole 1 703, a through hole 1 703 in the sliding rod 1 702 coincides with the through hole 1 703 in the rotating rod 701 and is fixedly connected through a screw and a nut 707, the end extending from the sliding rod 1 702 is fixedly connected to the connecting rod 704, the interior of the connecting rod 704 is slidably connected to the sliding rod 2 705, the interior of the sliding rod 2 705 is arrayed and penetrated by Several through holes 706 are provided. A through hole 706 is provided inside the connecting rod 704. A through hole 706 inside the second sliding rod 705 overlaps with a through hole 706 inside the baffle 2 and is fixedly connected thereto with a screw and nut 707. An extension rod 708 is fixedly connected to the side of the end extending from the second sliding rod 705. An outer rod 709 is sleeved on the outer surface of the extension rod 708 and is rotatably connected thereto. A point on the outer surface of the outer rod 709 is fixedly connected to the pedal 9. By telescoping the first sliding rod 702 and the second sliding rod 705, the different through holes 703 and 706 are made to overlap with the through holes 1 703 and 706 on the surfaces of the rotating rod 701 and the connecting rod 704. The screw and nut 707 are then passed through and installed to adjust the device. In actual use, the screw and nut 707 can be hand-tightened, making adjustment more convenient for medical staff.

[0025] like Figure 4As shown, in some embodiments, a threaded hole 11 is provided on the side wall of the connecting frame 6. A screw 10 is threadedly connected to the inner thread of the threaded hole 11. The end of the screw 10 extending into the interior of the connecting frame 6 is fixedly connected to a pad 12. Specifically, by rotating the screw 10, the pad 12 is pushed inward. When the pad 12 contacts the surface of the roller 8, it increases the friction to be offset by the rotation of the roller 8 and the rotating rod 701, thereby increasing the resistance during patient training and facilitating appropriate adjustments for patients at different recovery stages. In actual use, it can be replaced with a rotary damper or magnetic damper at an additional cost to increase the resistance.

[0026] like Figure 3 As shown, in some embodiments, a stopper 13 is fixedly connected to the surface of the pedal 9 near the bottom edge, and the middle part of the pedal 9 is fixedly connected to the two ends of the strap 14. Specifically, the patient's foot can be fixed by padding the heel of the patient with the stopper 13 and wrapping the strap 14 around the instep of the patient, thereby avoiding the loose connection between the foot and the pedal 9 during retraining and affecting the use.

[0027] like Figure 5 As shown, in some embodiments, the fixing assembly 3 includes a splint 1 301 and a splint 2 303, and the splint 1 301 and the splint 2 303 are located on both side surfaces of the baffle 2, and the top of the splint 1 301 is fixedly connected to the connecting block 1 302, and the top of the splint 2 303 is fixedly connected to the connecting block 2 304, and the internal rotation of the connecting block 1 302 is connected to the end of the threaded rod 305, and the threaded rod 305 passes through the interior of the connecting block 2 304 and is threadedly connected to the connecting block 2 304. Specifically, the threaded rod 305 is rotated to push the connecting block 2 304 and the splint 2 303 forward, so that the splint 1 301 and the splint 2 303 are clamped and fixed on the baffle 2, thereby achieving the fixation of the device, and compared with placing it on the bed, there is no need to lift the mattress and then install it, so it has better stability, and it does not affect the placement of the legs and feet when it is not stored normally.

[0028] like Figure 5 As shown, in some embodiments, the outer surface of the connecting block 2 304 is fixedly connected to the extension tube 15, the threaded rod 305 passes through and is threadedly connected to the inside of the extension tube 15, and a reinforcing rib 16 is fixedly connected between the surface of the extension tube 15 and the surface of the clamp 2 303. Specifically, by installing the reinforcing rib 16, the pressure when the threaded rod 305 is tightened can be more evenly distributed to the lower area of ​​the clamp 2 303, making the clamping more stable.

[0029] like Figure 6As shown, in some embodiments, a slot 17 is provided on the inner side of the connecting plate 4 through the bottom, and an inserting plate 18 is symmetrically arranged and fixedly connected to the side surface of the splint 301, and the slot 17 vertically slides to connect the inserting plate 18.
