Description

一种放射治疗用组织补偿胶及其制备方法
技术领域
本发明属于医疗器械领域,涉及一种放射治疗用组织补偿胶及其制备方法。
背景技术
放射治疗有着疗效显著、副作用低等优势,已经成为癌症治疗的重要手段。然而由于放疗射线“建成区效应”的存在,当对浅表肿瘤进行放射治疗时,往往难以保证病灶区域射线剂量的最大化,对此临床上常采用组织补偿胶来增加皮肤表面的建成深度从而提高目标区域的剂量。目前常用作组织补偿胶的材料有薄膜塑料水袋、石蜡、低密度聚乙烯、凡士林、特殊硅胶等。然而这些材料多存在服帖性较差,与体表轮廓往往存在空气间隙,导致二次“建成效应”,加重皮肤损伤的问题;且这些材料表面较光滑,难以固定于人体表面,容易滑动甚至脱落,导致放疗效果不理想;另外,像石蜡、凡士林等材质还存在密度较低,与人体组织剂量学参数相差较远,组织补偿效果较差等问题。
发明内容
为克服现有技术的上述缺点,本发明提供一种放射治疗用组织补偿胶及其制备方法,所述组织补偿胶含水率为48%-56%,剂量学参数与人体软组织十分接近,且该补偿胶硬度低,粘性好,改善了传统组织补偿胶与皮肤贴合以及固定的问题,能有效提高浅表肿瘤的放射治疗效率。
为实现上述目的,本发明采取的技术方案为:
一种放射治疗用组织补偿胶,所述组织补偿胶包括以下重量份原料:
30~50份含硅单体、45~65份亲水单体、2~3份交联剂、2~3份增粘剂、0.1~0.3份引发剂、0.1~0.3份促进剂。
所述原料配方制备的组织补偿胶硅水凝胶体系含水率为48%-56%,与人体组织的相似性和相容性较好,剂量学参数更接近于人体组织的参数,而且引进增粘剂对所述组织补偿胶粘附力有明显改善,用于放射治疗时能够很好的保证与皮肤间的密着性,能够更好的保证浅表肿瘤的放射治疗效果。
作为本发明所述放射治疗用组织补偿胶的优选实施方式,所述含硅单体为甲基-二(三甲基硅氧烷基)-甲烷基丙基甲基丙烯酸甘油酯,或者甲基-二(三甲基硅氧烷基)-甲烷基丙基甲基丙烯酸甘油酯和甲基丙烯酰氧丙基三(三甲基硅氧基)硅烷组成的混合物。
更优选地,所述甲基-二(三甲基硅氧烷基)-甲烷基丙基甲基丙烯酸甘油酯和甲基丙烯酰氧丙基三(三甲基硅氧基)硅烷组成的混合物中甲基-二(三甲基硅氧烷基)-甲烷基丙基甲基丙烯酸甘油酯与甲基丙烯酰氧丙基三(三甲基硅氧基)硅烷质量比为1:0.5~1。
作为本发明所述放射治疗用组织补偿胶的优选实施方式,所述亲水性单体为N-乙烯基吡咯烷酮与甲基丙烯酸β-羟乙酯的混合物。
更优选地,所述N-乙烯基吡咯烷酮与甲基丙烯酸β-羟乙酯质量比为1:1~3:1。
作为本发明所述放射治疗用组织补偿胶的优选实施方式,所述交联剂为数均分子量800~1000的聚乙二醇二丙烯酸酯。
作为本发明所述放射治疗用组织补偿胶的优选实施方式,所述增粘剂为数均分子量2800-3500,M/Q为0.7~0.8,乙烯基含量为1.2%的MQ硅树脂。
MQ硅树脂是由含有四官能度硅氧烷链节(SiO4/2,Q)的有机硅化合物与含有单官能度硅氧烷链节(R3SiO1/2,M)的有机硅化合物进行共水解-缩聚反应生成的三维球型结构的硅酮脂,MQ硅树脂中的有机部分能提高其与所述补偿胶的相容性,起增粘作用;硅氧链节或乙烯基能提高所述补偿胶的力学强度、内聚强度及剥离强度,起补强作用。所述MQ硅树脂的分子量、M值、乙烯基含量等参数会影响树脂与配方体系的相容性,体系交联强度、含水率及粘性等性能参数,数均分子量2800-3500,M/Q为0.7~0.8,乙烯基含量为1.2%的MQ硅树脂可以使上述性能达到最佳状态。
作为本发明所述放射治疗用组织补偿胶的优选实施方式,所述引发剂为体积分数为10%的过硫酸铵水溶液。
作为本发明所述放射治疗用组织补偿胶的优选实施方式,所述促进剂为四甲基乙二胺。
另外,本发明提供了所述放射治疗用组织补偿胶的制备方法,包括如下步骤:
将含硅单体、亲水单体、交联剂、增粘剂、引发剂及促进剂混合均匀后,导入模具中,常温下反应5-6h,然后加热至50-80℃反应4-8h,脱模,置于去离子水中浸泡18-24h,并隔2-6小时换一次水,得到所述组织补偿胶。
所述放射治疗用组织补偿胶的制备方法中,将原料在常温下反应一定时间是为了使配方体系进行初步的聚合及交联固化,而过早的加热反应会使聚合反应速度加快出现“爆聚”而影响最终产品性能。
与现有技术相比,本发明的有益效果为:构建的硅水凝胶体系含水率为48%-56%,与人体组织的相似性和相容性较传统的组织补偿胶材料更好,剂量学参数更接近于人体组织的参数,且通过向该补偿胶中引入增粘剂,使其与人体皮肤有着良好的粘附性,用于放射治疗时能够很好的保证与皮肤间的密着性,不会出现空腔以及移位、脱落等问题,能够更好的保证浅表肿瘤的放射治疗效果。
