Air bed device

The present invention relates to an inflatable cushion carrying a patient's body, and more particularly to an inflatable bed device for installing an inflation blower inside a bed.

When the human body is unable to move freely or move away from the bed for a reason, it often causes poor blood circulation due to prolonged compression, and hemorrhoids occur due to tissue necrosis. Therefore, in order to avoid acne caused by inconvenient movement, an exchange inflatable air bed is derived. come out.

The conventional exchange air bed has a plurality of air bags that can be inflated and exhausted, and the air bubbles are alternately inflated and exhausted by a blower, so that the body of the inconvenient person can be decompressed and effectively reduce the occurrence of hemorrhoids. Probability.
