Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a lower limb lifting and lowering device. Background Art

[0002] Lower limb lifting devices are usually used in medical, rehabilitation and home care situations to assist people with limited mobility, postoperative patients or people who have been bedridden for a long time to adjust the position of their lower limbs to promote blood circulation, reduce swelling, prevent complications such as deep vein thrombosis, or to relieve lower limb fatigue caused by standing or sitting for a long time.

[0003] In clinical practice, pillows and cushions are often used to elevate the lower limbs, but these methods have many shortcomings. The support of pillows and cushions is often not stable enough to ensure that the raised lower limbs remain in an ideal posture after a long time, and their height and angle adjustment are not precise enough.

[0004] After searching, the Chinese utility model patent with the authorization announcement number CN219963296U proposes a patient lower limb lifting pad, which relates to the field of medical device technology, including a load-bearing plate and a support plate, the outer wall of the load-bearing plate is symmetrically fixed with connecting plates on both sides, the bottom surface of the connecting plate is symmetrically fixed with rollers on both sides, the top surface of the load-bearing plate is fixed with a fixed plate, and the end of the fixed plate away from the load-bearing plate is configured with a placement groove and the inner wall of the placement groove is slidably connected with a movable plate. The utility model, through the arrangement of the load-bearing plate, the connecting plate, the support plate, the roller, the soft bag and the movable plate, can facilitate the staff to push the device to the patient's bedside, so that the load-bearing plate and the connecting plate are located at the bottom of the bed, and the soft bag is located above the bed board, so that the patient can pad the ankle on the soft bag, thereby reducing the occurrence of common clinical complications such as blood circulation disorders, lower limb edema, and lower limb deep vein thrombosis. In addition, the arrangement of the fixing mechanism and the movable plate can also adjust the height of the soft bag, so that the device is suitable for different situations.

[0005] However, this patent has the following shortcomings. First, this patent can only adjust the height of the soft bag, but cannot adjust the angle of the soft bag, which results in poor fit between the soft bag and the patient's leg, or causes the patient's calf and thigh to be not in a straight line, which is not conducive to blood return. Secondly, this patent uses a pin to adjust the height, which cannot be adjusted linearly and the operation of adjusting the height is cumbersome and time-consuming.

[0006] Based on this, the utility model provides a lower limb raising and lifting device. Utility Model Content

Specifically, the angle is controlled by rotating the screw rod to pull the pull rod around the second rotating rod, thereby driving the support block to rotate, and then adjusting the angle of the bearing part. The use of a screw rod for driving can make the angle adjustment highly optional, and the screw rod itself has a self-locking function, which can well maintain the angle of the bearing part; a scissor-type lifting device driven by a screw rod is used, and the right end of the lifting control screw rod is upward by arranging the connecting rod group, so as to facilitate the rotation of the lifting control screw rod when performing lifting adjustment; the bearing groove, baffle plate, and supporting foot are arranged on the bearing part to better fit the patient's legs to provide better comfort.
