Description

Medical Adjustable Seat

technical field

The utility model relates to a seat, in particular to a medical adjustable seat.

Background technique

The human hip joint is a spherical joint consisting of a spherical femoral head and a bowl-shaped acetabulum. It is the joint formed by the femur (femur) and the pelvis. Both the spherical surface and the inner surface of the bowl are covered with smooth cartilage, and the synovial membrane secretes mucus to minimize friction. When the hip joint becomes diseased, the cartilage is no longer smooth, the synovial bursa becomes inflamed and shrinks, and the joint can no longer function as well as it normally does. When the hip joint is painful, stiff or deformed due to degeneration, disease or trauma, or even has limited mobility, and the symptoms cannot be relieved by drugs or other treatments, the patient is usually replaced with an artificial hip joint by surgery to allow the patient to resume daily activities Ability, if a hip fracture occurs, depending on the extent of the injury, surgery may sometimes be used.

Patients who stay in bed for a long time after hip fracture surgery are prone to complications such as pressure sores, lung infections, and urinary tract infections. Long-term bed rest lacks stress to promote bone healing, and is prone to osteoporosis, which affects bone healing. At present, after hip fracture surgery, patients are required to strengthen functional exercises and sit up as early as possible, which can effectively reduce various postoperative complications, improve patients' daily activities of life, and promote early recovery.
