【技术实现步骤摘要】
易剥离医用留置针贴
本技术涉及一种医用留置针贴,特别是公开一种易剥离医用留置针贴,应用于医疗卫生领域。
技术介绍
医用留置针贴多用于在输液时固定留置针用或是固定其他输液用针头和导管用,其基材是0.025mm厚的聚氨酯薄膜,聚氨酯薄膜对皮肤的顺应性好,黏贴舒适,但由于聚氨酯薄膜很薄,所以在生产时会加一层背衬(PET或纸)以方便使用,背衬在聚氨酯薄膜贴好后要撕掉。现有的医用留置针贴是在背衬上复合聚丙烯剥离条,然后再模切成型,但由于需要先对剥离条进行涂胶,再将剥离条与背衬复合,使得生产工序较为繁复,成本较高。
技术实现思路
本技术的目的在于解决现有技术的缺陷,提供一种生产工序简便、降低生产成本的医用留置针贴,公开一种易剥离医用留置针贴。本技术是这样实现的:一种易剥离医用留置针贴,包括聚氨酯薄膜、背衬层、医用压敏胶层、吸水垫、防粘层,其特征在于:所述聚氨酯薄膜的背面设有所述背衬层,所述背衬层中间设有S形易剥离开口,所述聚氨酯薄膜的正面涂布有所述医用压敏胶层,所述医用压敏胶层上设有所述吸水垫,所述吸水垫设置在所述医用留置针贴中心位置处,所述吸水垫上设有所述防粘层;所述医用留置针贴的底部中间位置处设有开口向下的U形槽,所述吸水垫设置在所述U形槽上方。所述防粘层由两片离型纸组成,两片离型纸的一侧在所述吸水垫上方交接并重叠,两片离型纸的另一侧分别与所述医用压敏胶层相贴合。所述背衬层为PET层或纸。所述聚氨酯薄膜的厚度为0.020mm~0.025mm。本技术的有益效果是:本技术的结构简单、生产工序简便,降低了生产成本,提高了生产效率;本技术对皮肤的顺应性好、黏贴舒适;本技术在背 ...
