    • Hydrolytically degradable polymers in the form of biodegradable disposable medical devices for use in medicine and laboratories such as syringes, test tubes, catheters, tubing, trays, medical fabrics, and gloves are described. The devices are formed in whole or in part of a hydrolytically degradable polymer. In the preferred embodiment, the devices or structural components thereof degrade in a period of weeks to months, preferably within a year and more preferably within six months of exposure to aqueous solutions. Conventional hydrolytically degradable polymers may be utilized or these may be modified to increase mechanical or processing characteristics, for example, using a polyfunctional branching agent and/or a chain extending agent. In one embodiment, the hydrolytically degradable polymer is a member of a class of polyesters comprising an aliphatic dicarboxylic acid, an aliphatic diol and optionally, one or more bifunctional fatty acids, such as ricinoleic acid and/or castor oil. The devices are prepared using standard techniques, such as by injection molding, extrusion or melt spinning. The devices can be formed entirely of the degradable polymer, or they can be coated with a polymer coating, optionally formed of a non-biodegradable polymer, in order to increase the compatibility of and reduce the possibility for interaction between the surface of the device and liquids that may come in contact with the device, or they may include core or other internal structural member formed of either the biodegradable or non-biodegradable material and a coating of either a biodegradable or non-biodegradable material.
    • 描述了用于医学和实验室的生物可降解一次性医疗装置形式的水解可降解聚合物,例如注射器,试管,导管,管道,托盘,医用织物和手套。 该装置全部或部分由可水解降解的聚合物形成。 在优选实施方案中,所述装置或其结构组分在暴露于水溶液的数周至数月内,优选在一年内,更优选在六个月内降解。 可以使用常规的可水解降解的聚合物,或者可以对这些聚合物进行改性以增加机械或加工特性,例如使用多官能支化剂和/或扩链剂。 在一个实施方案中,可水解降解的聚合物是包含脂族二羧酸,脂族二醇和任选地一种或多种双官能脂肪酸如蓖麻油酸和/或蓖麻油的一类聚酯的成员。 这些装置使用标准技术制备,例如通过注塑,挤出或熔融纺丝。 这些装置可以完全由可降解聚合物形成,或者它们可以涂覆有聚合物涂层,任选地由不可生物降解的聚合物形成,以便提高装置表面的相容性并降低装置表面与 可能与设备接触的液体,或者它们可以包括由生物可降解或不可生物降解材料和可生物降解或不可生物降解材料的涂层形成的芯或其他内部结构构件。
