Description

An adjustable inflatable lower limb cushion

Technical field:

The utility model relates to the technical field of medical aids, in particular to an adjustable inflatable lower limb cushion.

Background technique:

Clinically, in some patients with lower extremity trauma, after tibia and fibula fractures and foot trauma, the blood flow from the extremities to the heart is slow, resulting in obvious swelling of the lower extremities, and the swelling of the calf is prone to osteofascial compartment syndrome. At present, lower extremity pillows are often used to raise the lower extremities to reduce edema. Most of the existing lower extremity cushions are made of sponge material with a fixed shape, and there are some problems in practical application: 1. Different patients have different height requirements, and ordinary lower extremity pillows cannot adjust the height. When the height needs to be raised, it is necessary to It is more inconvenient to use other items to further raise the height; 2. Different patients have different leg sizes, and the front end of the common lower limb pillow has a fixed inclination angle. When the patient's thigh is thick, the knee of the leg will be too high due to the thigh support. However, it cannot fit with the lower limb pillow, and there is a gap, which causes the patient's legs to be too tired and affects the use effect. The patent application number CN201520654465.5 sets an inflatable cavity inside the pillow, and adjusts the angle and height of the support body by adjusting the amount of inflation in the inflatable cavity, but this inflation adjustment method requires the inflatable cavity to be made of elastic materials. After the lower limb is placed on the support body, the inflatable cavity will be compressed and deformed under the action of the gravity of the lower limb. When the inflatable cavity is inflated to adjust the angle and height, the shape of the inflatable cavity will change under the dual action of the air pressure and the gravity of the lower limb, sometimes Lateral expansion and deformation will occur instead of vertical expansion to push up the support body, which cannot achieve the effect of accurately adjusting the height and angle of the support body.
