Abstract: A polymer hydrogel with a slow-release function, and a preparation method and use thereof are provided. The polymer hydrogel includes the following components in mass percentage contents: 0.01% to 15% of an active ingredient, 0.01% to 15% of an ion inhibitor, 0.01% to 1% of a crosslinking agent, 0.1% to 10% of a polymer resin, 10% to 35% of a solvent, 0.1% to 15% of a skin-touch regulator, 10% to 55% of deionized water, 0.1% to 3% of an appearance modifier, 0.01% to 1% of a crosslinking regulator, 0.01% to 1% of a preservative, and 0.01% to 5% of a transdermal absorption enhancer. The polymer hydrogel prepared by the present disclosure has excellent skin adaptability and skin permeability, long drug slow-release time, and excellent bioadhesion to the skin, and can be repeatedly peeled off without residue.

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.
