    • The instant invention pertains to a method and a fluid composition for producing contact lenses with improved lens quality and with increased product yield. The method of the invention involves adding a non-crosslinkable hydrophilic polymer into a fluid composition including a lens-forming material in an amount sufficient to reduce an averaged mold separation force by at least about 40% in comparison with that without the non-crosslinkable hydrophilic polymer and to provide a disparity of about 10 N or less in mold separation force. The non-crosslinkable hydrophilic polymer has a limited miscibility with the lens-forming material low enough to successfully and timely form an intact interfacial film with a sufficient thickness at an interface between the mold and the fluid composition therein, and has a structure that minimizes entanglement of the non-crosslinkable hydrophilic polymer in the interfacial film with the polymer matrix of the formed lens.
    • 本发明涉及一种用于制造具有改善的镜片质量和增加的产品产量的隐形眼镜的方法和流体组合物。 本发明的方法包括将不可交联的亲水性聚合物添加到包含透镜形成材料的流体组合物中,该透镜形成材料的量足以将平均的模具分离力减小至少约40%,与没有不可交联的亲水性 并且在模具分离力中提供约10N或更小的差异。 不可交联的亲水性聚合物与透镜形成材料的混溶性有限,足够低以在模具和其中的流体组合物之间的界面处成功地及时地形成具有足够厚度的完整界面膜,并且具有最小化缠结的结构 的界面膜中的不可交联的亲水聚合物与形成的透镜的聚合物基体。

    • The invention concerns a device (1) for wetting a medical equipment component (20) with a liquid medium (M), having a dispenser (10) for applying the liquid medium (M) to a section (200) of the component (20) that is to be wetted. A device of this type is characterized by a suction device (12) for drawing off at least a portion of the liquid medium (M) from the section (200) of the component (20) that is to be wetted. The invention furthermore concerns a method for wetting a component. In this manner, a device and a method for wetting a component with a liquid medium is created, with which a wetting procedure can be executed in an at least partially automated manner, at least partially reducing the risk thereby of blockage at the opening of the component as a result of too much liquid being applied.
    • 本发明涉及一种用于用液体介质(M)润湿医疗设备部件(20)的装置(1),其具有用于将液体介质(M)施加到部件(20)的部分(200)的分配器(10) )要润湿。 这种装置的特征在于用于从待润湿的部件(20)的部分(200)抽出至少一部分液体介质(M)的抽吸装置(12)。 本发明还涉及润湿组分的方法。 以这种方式,产生了用液体介质润湿组分的装置和方法,利用该装置和方法可以以至少部分自动化的方式执行润湿程序,至少部分地降低了在开口处的堵塞的风险 作为施加过多液体的结果的组分。
