Pressure control assembly for an air mattress
摘要:
An apparatus for controlling the pressure of fluid within a chamber upon which a person rests includes a manifold (40) having a wall defining an interior region (54) in fluid communication with a source of pressurized fluid (60) and an air sack (70) defining the chamber. The air sack (70) includes a wall defining an interior region (80, 82, 84, 86) of the air sack (70). The wall is formed to include an air loss opening (140) in fluid communication with the interior region (80, 82, 84, 86) of the air sack (70). The apparatus also includes a flow control assembly (88, 90, 92, 94) having a conduit (136) in fluid communication with the interior region (80, 82, 84, 86) of the air sack (70) and with the interior region (54) of the manifold (40). The flow control assembly (88, 90, 92, 94) also includes a check valve (130) mounted in the conduit (136) to prevent the flow of pressurized fluid through the conduit (136) from the interior region (80, 82, 84, 86) of the air sack (70) to the interior region (54) of the manifold (40).
