Description

Technical Field

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

[0002] After a fracture, whether the patient is fixed with plaster or internally fixed with surgery, the surgical site will be congested and swollen. In addition to conventional drug treatment, raising the affected limb can reduce the swelling and increase the blood flow back to the heart, which can further shorten the fracture healing time. Especially for patients with lower limb fractures, since they need to be immobilized after the fracture, raising the limb can speed up the circulation and prevent the formation of lower limb venous thrombosis.

[0003] Most hospitals routinely use straps to lift the patient's legs. However, this method makes the patient's legs always hang, which is less comfortable and prone to shaking, making the stability of the restraint less stable. Some hospitals also use multiple pillows to place under the affected limb and use the height of the stacked pillows to lift the affected limb. This method requires the use of multiple pillows, which is easy to cause waste. It is also inconvenient to adjust the lifting angle when using pillows to raise the limb, which is troublesome to use. In addition, the pillows are unstable when stacked, and the affected limb is easy to fall, causing secondary injuries to the patient.

[0004] The Chinese utility model patent with application number CN202121259689.1 discloses a lower limb lifting pad, including a base plate, a first mounting plate fixedly installed in the middle of the upper part of the base plate, a second mounting plate fixedly installed on one side of the base plate, a first slide rail and a second slide rail fixedly installed between the first mounting plate and the second mounting plate, a first slider sleeved on the first slide rail, a first connecting plate fixedly installed on the other side of the base plate, the first connecting plate is hinged to a first support plate through a first rotating shaft, the first support plate is hinged to a first support frame through a third rotating shaft, a first sleeve is fixedly installed on the upper side edge of the first slider, and the bottom end of the first support frame is inserted into the first sleeve. However, although the utility model does not require a pillow to raise the pad or to lift it up, the height of the lower limb lifting pad can be adjusted according to the needs of the patient and the patient's comfort is enhanced. However, the lower limb lifting pad requires manual fixation of the second support frame, and the fixing device needs to be operated during the fixing process of the second support frame. There are many fixing steps and it cannot be fixed quickly. In addition, when using the lower limb lifting pad, the thigh will appear to be suspended in the air, making the patient feel uncomfortable. Utility Model Content
