贴膏治疗仪外壳的注塑模具设计 摘要 LED紫外线贴膏治疗仪为一种治疗仪器，专门配合药物来治疗皮肤癌症，是一种新型的医疗器械。本设计主要对治疗仪的造型进行设计，充分考虑其功能性，提高使用舒适度和便携度，并选择支撑架即中间层进行模具设计。 设计中，参考现有市面造型，对外形及内部结构进行重新设计，并使用solidworks对零件进行建模，并进行应力分析和掉落测试。模具设计中模架选择中小型标准模架，其余零件按照标准选择标准零件。 贴膏治疗仪做到了近距离治疗，高效率治疗，低成本治疗，高安全性的治疗。对于治疗皮肤癌来说，低成本和高度的安全性是其未来的发展趋势。而LED紫外线贴好治疗仪将会成为带动此趋势的新一代不可缺少的产品。 贴膏治疗仪能够使患者在家使用，大量减少患者的治疗时间，节省患者的精力，节约患者的金钱。同时，治疗仪配合相应的药物，也可为患者减少手术化疗等方法的时间，使患者的痛苦大大降低。 关键词：治疗仪；模具；注塑；分析 ABSTRACT LED ultraviolet plaster therapy i
