Solid medical ultrasonic coupling paster and preparation method thereof

The invention relates to a solid medical ultrasonic coupling paster and a preparation method thereof. The solid medical ultrasonic coupling paster is prepared from, by weight, 20-40% of water-based polymer gel, 2-6% of alginic acid trimethylene glycol ester, 2-8% of fatty acid trihydric alcohol monoester, 6-12% of humectant, 0.01-0.05% of corrosion remover and the balance deionized water, wherein the water-based polymer gel is composed of water-based acrylic copolymer and modified sesbania gum with the weight ratio being (0.5-1):(2-4). The solid medical ultrasonic coupling paster is stable to light and heat, has the acoustic performance closest to human soft tissue, high in ultrasonic diagnosis accuracy, has the good biocompatibility, and is free of toxin to skin cells, free of sensitization and stimulation and high in safety. 本发明涉及种固态医用超声耦合贴片及其制备方法。所述的固态医用超声耦合贴片由以下重量百分比计的组分组成：水性聚合物凝胶20～40％、海藻酸丙二醇酯2～6％、脂肪酸三元醇单酯2～8％、保湿剂6～12％、防腐剂0.01～0.05％、余量为去离子水，其中，水性聚合物凝胶由水溶性丙烯酸共聚物和改性田箐胶以(0.5～1):(2～4)的重量比组成。本发明提供的固态医用超声耦合贴片对
