Abstract
An airbag cushion assembly includes an airbag cushion and an inflation-deflation apparatus that communicates with the airbag cushion. The airbag cushion includes a plurality of sub-airbags, and an airbag gap is formed between adjacent sub-airbags. The inflation-deflation apparatus is provided with an exhaust port, the exhaust port is provided in the airbag gap, and the inflation-deflation apparatus is configured to inflate and deflate the airbag cushion. For the airbag cushion assembly, the exhaust port is provided in the airbag gap, air exhausted by the airbag cushion takes away damp air accumulated between a patient and the airbag cushion, to reduce humidity of the contact area between the patient and the airbag cushion, thereby achieving a pressure sore prevention effect.
