In general, patients who are forced to live in a state of lying (laying) due to central nervous system abnormalities or other lesions are not allowed to change their position within a certain period of time to prevent pressure sores. This is a recommendation of the U.S. Sores Advisory Committee (NPUAP), which is to maintain a 30 ° side position where contact pressure and shear forces are minimized (The 30 Degree Rule: JoAnn Maklebust, Mary). Sieggreen, 'Pressure Ulcers Guidelines for Prevention and Nursing', 1991) In general, two or more caregivers use a device such as a pillow or sponge after lifting a patient to change their position.

Conventional methods of preventing bedsores include the Nutritional and skin care assessment, but it is controversial (Lange, Bates-Jensen, 2003). Regarding pressure, which is the most important cause of pressure sores, reduce the contact pressure (body pressure) on the body skin below the minimum pressure at which the blood circulation of capillaries occurs, or change the posture to move the area where the pressure is concentrated Etc. are widely used (Kosiak, 1959). Pressure-reducing devices (static or dynamic) are used to apply this method (Thomas, 2006), but there are controversies about their useful effects (Reddy, 2006).

Some of the levitation air mattresses do not have the effect of dispersing body pressure, but rather concentrate the body pressure, causing moisture caused by the mattress material, causing pressure sores, and insufficient effects even when the tilting function is applied. Appearing.

In addition, there is a high possibility of avoiding position changes due to cumulative fatigue of the caregiver, it is difficult to confirm the change time when one caregiver is responsible for a large number of patients, and there is a high possibility of causing caregiver's musculoskeletal disorders due to periodic position changes. In addition, the development of pressure sores increases the likelihood of medical disputes with medical staff.

Twenty percent of the 3 percent incidence of medical malpractice in the U.S. was found to be dead, with the largest number of medical malpractice being 45,305,305, accounting for 40.53 percent of the total.

Therefore, it is necessary to develop an automatic posture converting mattress technology that periodically converts the patient's position sufficiently, minimizes compressive and tensile stresses and shear forces from the skin, and distributes contact pressure due to weight.
