Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a lower limb elevation pad. Background Technology

[0002] In the treatment and rehabilitation of patients with lower limb diseases, leg elevation pads are often used to elevate the lower limbs. These conditions include deep vein thrombosis, lymphatic drainage disorders, and fractures, as these are often accompanied by lower limb swelling. Leg elevation pads effectively raise the leg position, improve blood circulation in the lower limbs, and prevent varicose veins and edema. Varicose veins and edema are usually caused by prolonged standing or sitting, leading to obstructed blood return. Using an elevation pad can reduce pressure on the lower limb veins and promote blood return. Patients should place their legs on the elevation pad while lying down, for 30 minutes to 1 hour each time. Regular use can significantly improve leg blood circulation and reduce swelling and discomfort.

[0003] However, currently available foam elevating pads are too short. For patients who are short, the end of the elevating pad cannot reach the foot of the bed, resulting in a change in the position of the lower limbs on the pad. The elevating pad cannot play its proper role, and the patient's lower limb discomfort increases. Furthermore, the elevating pad does not have a full-length slope, and the slope cannot be adjusted, which is not conducive to reducing swelling. Utility Model Content

[0004] The existing lower limb elevation pads have technical problems: the tail end of the pad cannot be placed against the foot of the bed, which causes the lower limbs to change position on the pad and thus fails to play their proper role, increasing patient discomfort. In addition, the slope of the lower limb elevation pad cannot be adjusted, which is not conducive to reducing swelling.

[0005] The technical solution of this utility model is as follows: a lower limb elevation pad, including a base plate; characterized in that: it also includes a drive motor and a fixing component; a drive motor is provided on one side of the base plate, a threaded rod is provided at the output end of the drive motor, a support slider is threadedly connected to the threaded rod, one side of the support slider is hinged to one end of a support rod, a rotating plate is hinged to the base plate, the other end of the support rod is hinged to a fixing block, the fixing block is fixedly connected to the bottom of the rotating plate, a lower limb elevation pad body for elevating the lower limb is provided at the upper end of the rotating plate, a fixing component is provided on one side of the lower limb elevation pad body; guide blocks are provided on both sides of the base plate, a sliding abutment is slidably connected to the inner side of the guide block, a rotating rod is rotatably connected to one side of the sliding abutment, a movable block is provided on one side of the rotating rod, and a limit tooth is provided in the guide groove of the guide block.

[0006] Preferably, two sets of support rods are provided, and the two sets of support rods are symmetrically arranged on the outside of the support slider.

[0007] Preferably, the guide block, sliding abutment, rotating rod, movable block and limiting tooth are provided in two sets. The two sets of guide blocks, sliding abutment, rotating rod, movable block and limiting tooth are symmetrically arranged on both sides of the base plate.

[0008] Preferably, the rotating plate is connected to the connecting block on the surface of the base plate via a hinge structure.

[0009] Preferably, the fixing component includes a first Velcro strap, with the upper end of the rotating plate having the first Velcro strap, the lower end of the lower limb elevation pad having a second Velcro strap, a strap for fixing the lower limbs being provided on one side of the lower limb elevation pad, a male buckle being provided on one side of the strap, a fixing strap being provided on one side of the lower limb elevation pad, and a female buckle being provided on one side of the fixing strap.

[0012] Preferably, the strap is detachably connected to the lower limb elevation pad body.

[0013] The beneficial effects of this invention are as follows: Compared to traditional lower limb elevation pads, where the tail end cannot be pressed against the foot of the bed, resulting in a change in the position of the lower limbs on the pad and thus failing to provide the intended effect, increasing patient discomfort, and the inability to adjust the slope of the pad hindering swelling reduction, this device addresses this issue. By pulling a sliding abutment, the abutment slides inside a guide block, causing a rotating rod to move, which in turn moves a movable block. Limiting teeth ensure unidirectional movement of the sliding abutment, with one side of the abutment pressed against the bed to prevent the base plate from sliding backward. Activating the drive motor rotates a threaded rod, which in turn moves a support slider, which in turn moves a support rod. The support rod, through a fixed block, causes a rotating plate to rotate outside the connecting block, which in turn rotates the lower limb elevation pad itself, thus adjusting the support angle and improving its effectiveness.
