Abstract
本发明公开了使有机硅水凝胶透镜制剂脱气的方法。
Description
本发明涉及眼科透镜的制备,特别是由有机硅水凝胶制剂制成的透镜。
相关专利申请
本专利申请为提交于2007年4月6日的美国专利申请No.60/910,473的非临时性申请。
背景技术
眼科透镜(特别是软性隐形眼镜)是由单体的混合物制成,这些单体可以聚合成能够用水溶胀的硬性物质。最初,眼科透镜由不包含有机硅的水凝胶制剂制成。最新的发展已经得到了包含有机硅单体和大分子单体的水凝胶。由于其氧气渗透性好以及其他因素,因此通过这些材料制成的眼科透镜非常受欢迎。然而,这些材料的制备与不含有机硅的水凝胶的制备不同。
通过聚合来形成有机硅水凝胶的这些制剂在进行聚合之前必须使其脱气。如果未将这些材料脱气,则制成的透镜会含有许多碎屑、孔、气泡和泪状物。为避免此问题,通常使用多种未合并到生产线中的技术(旋转蒸发器、氮气吹扫等等)来使有机硅水凝胶制剂脱气。如果使有机硅水凝胶制剂脱气的方法能并入生产线中,那将会非常有利。有机硅水凝胶与不含有机硅的水凝胶都存在相同的问题。美国专利No.5,435,943解决了不含有机硅的水凝胶的这个问题,该专利据此全文以引用方式并入。将该脱气器并入生产线中,并充分减少了不含有机硅的水凝胶中溶解的气体。然而,该专利的脱气器对有机硅水凝胶并不奏效。因此,找到一种可以并入生产线并且使有机硅水凝胶脱气的脱气器将非常有用。以下发明解决了这个需要。
具体实施方式
本发明包括使液态单体制剂脱气的方法,该方法包括用径向液体流动通道脱气器来处理所述制剂。
如本文所用,“液态单体制剂”是指用于形成眼科透镜(例如软性隐形眼镜、人工晶状体、覆盖透镜、眼用膜剂、泪小管塞、以及光学植入物)的组分的混合物。本发明的优选液态单体制剂为用于制备软性隐形眼镜的有机硅弹性体、水凝胶、有机硅水凝胶、以及氟代水凝胶。软性隐形眼镜制剂在美国专利No.5,710,302、WO 9421698、EP 406161、JP2000016905、美国专利No.5,998,498、美国专利No.6,087,415、美国专利No.5,760,100、美国专利No.5,776,999、美国专利No.5,789,461、美国专利No.5,849,811、以及美国专利No.5,965,631中有所描述。上述参考文献据此全文以引用方式并入。特别优选的液态单体制剂是用于制备下列美国通用名称的软性隐形眼镜的那些制剂:acofilconA、alofilcon A、alphafilcon A、amifilcon A、astifilcon A、atalafilcon A、balafilcon A、bisfilcon A、bufilcon A、comfilcon、crofilcon A、cyclofilcon A、darfilcon A、deltafilconA、deltafilcon B、dimefilcon A、drooxifilcon A、epsifilcon A、esterifilcon A、etafilcon A、focofilcon A、galyfilcon A、genfilcon A、govafilcon A、hefilcon A、hefilcon B、hefilcon D、hilafilcon A、hilafilcon B、hioxifilcon B、hioxifilcon C、hixoifilcon A、hydrofilcon A、lenefilcon A、licryfilcon A、licryfilcon B、lidofilcon A、lidofilcon B、lotrafilcon A、lotrafilcon B、mafilcon A、mesifilcon A、methafilcon B、mipafilcon A、nelfilcon A、netrafilcon A、ocufilcon A、ocufilconB、ocufilcon C、ocufilcon D、ocufilcon E、ofilcon A、omafilconA、oxyfilcon A、pentafilcon A、perfilcon A、pevafilcon A、phemfilcon A、polymacon、senofilcon A、silafilcon A、siloxyfilcon A、tefilcon A、tetrafilcon A、trifilcon A、vasurfilcon、vifilcon、以及xylofilcon A。本发明更加特别优选的眼科装置为galyfilcon A、senofilcon A、genfilcon A、leNefilcon A、comfilcon、lotrafilcon A、lotrafilcon B、以及balafilcon A。更优选的透镜包括comfilcon、galyfilcon A、以及senofilcon A。最优选的透镜包括galyfilcon A和senofilcon A。
术语“径向液体流动通道脱气器”是指允许含气体的液体流经中空膜的装置。所述中空膜将溶解的气体从液体中除去。优选的径向液体流动通道脱气器为2×6径流SuperPhobic(2X6 Radial Flow SuperPhobic)(参见http://www.liqui-cel.com/uploads/documents/D82_Rev9_8-07_2x6%20SP%20Radial%20Flow3.pdf)和Liqui-Cel 6×28NBTM(由Liqui-制造),特别优选的径向脱气器为2×6径流SuperPhobic。
如本文所用,“处理”是指使液态单体混合物与径向液体流动通道脱气器接触的物理方法。所述眼科装置可以在聚合之后随时用抗过敏剂来处理。制备隐形眼镜的自动化工序包括以下步骤:使液态单体制剂聚合以形成盘,使用两个半模来旋转成型、或静态成型和聚合。参见美国专利No.4,495,313、4,680,336、4,889,664、3,408.429、3,660,545、4,113,224、以及4,197,266,所有这些专利全文均以引用方式并入。在任何这些步骤之后通常为从成型表面上移除、水合作用、检测、以及包装。本发明的方法特别有效,因为可以将其直接并入生产线中,从而节省时间和减少浪费的单体材料。
本发明的上述方法旨在解释本发明,并且提出体现本发明的方法和装置。熟知软性隐形眼镜生产和其他专业的人员可以找到实施本发明的其他方法。但是,应将这些方法视作本发明范围内的方法。
