This application relates to the field of
medical care and discloses an intelligent pneumatic positioning care
system. This
system enables elderly individuals to safely transition from a
lying to a sitting position without changing their existing
bed, providing ample lateral support throughout the process to prevent
rollover or falls. The
system includes: a wedge-shaped main
air cushion, used to elevate the upper body from a
lying to a sitting position after inflation; two side air cushions, respectively located on both sides of the main
air cushion's upper surface, used to provide lateral support after inflation; and a one-way valve with an opening pressure, located between the side air cushions and the main
air cushion. When the
pressure difference between the side air cushions and the main air
cushion is greater than the opening pressure, the one-way valve opens, allowing gas from the side air cushions to enter the main air
cushion; when the
pressure difference is less than the opening pressure, the one-way valve closes,
cutting off the gas connection between the side air cushions and the main air
cushion.
