Description
发明背景
本发明涉及抗微生物组合物和在各种医疗应用中使用这些组合物的方法。现代医学治疗的一个主要挑战是控制感染和微生物有机体的传播。
始终存在这种挑战的一个领域是各种类型的输液治疗。输液治疗是一种最普通的健康护理程序。就医、家庭护理和其他患者通过插入血管系统中的血管接入器械来接收流体、医药品和血液产品。可使用输液治疗来治疗感染、提供麻醉或使得痛觉缺失、提供营养支持、治疗肿瘤的生长、保持血压和心律、或用于许多其他临床上重要的用途。
通过血管接入器械可有助于输液治疗。所述血管接入器械可接入患者的外周或中心血管系统。所述血管接入器械可短期(数天)、中期(数周)或长期(数月到数年)留置。可将所述血管接入器械用于连续输液治疗或间歇治疗。
普通的血管接入器械是一种置入患者静脉内的塑料导管。所述导管的长度可从用于外周接入的几个厘米到用于中心接入的数厘米且可包括诸如经外周中心静脉置管(PICC)的器械。所述导管可经皮植入或通过外科手术植入患者皮肤之下。所述导管或连接到所述导管的任意一种其他血管接入器械可具有单一内腔或多个内腔以用于同时输入多种流体。
血管接入器械通常包括可连接到其他医疗器械的Luer适配器。例如,可将给药设备可一端连接到血管接入器械,而另一端连接脉注射物(IV)袋。所述给药设备是用于连续灌输流体和医药品的流体导管。通常,IV接入器械是可连接到另一个血管接入器械的血管接入器械,其可关闭所述血管接入器械并使得可间歇灌输或注射流体和医药品。IV辅助器械可包括外壳和用于关闭所述系统的隔片。所述隔片可用医疗装置的钝套管或阳式Luer打开。
当血管接入器械的隔片不能正常打开或设计特征具有缺陷时,可造成特定的并发症。与输液治疗相关的并发症可造成明显的病态,甚至死亡。一种显著的并发症是导管相关性血流感染(CRBSI)。在美国的医院中每年发生大约250000~400000个与BSI相关的中心静脉导管(CVC)病例。每次感染将死亡率提高约12%~25%且每个病例的健康护理系统的成本为25000~56000美金。
血管接入器械可充当感染的滋生地,导致散布BSI(血流感染)。因难以有规律地对所述器械进行冲洗、未消毒的置入技术、或因通过所述通道的任一端进入流体流动通道并随后进入导管置入物中的病原体可造成这种情况。当血管接入器械发生污染时,病原体粘附到所述血管接入器械,发生繁殖并形成生物膜。所述生物膜可抵抗大部分生物杀灭剂并为病原体提供了补充来源而进入到患者血流中,造成BSI。由此,需要具有抗微生物性能的器械。
阻止生物膜的形成和患者感染的一种方法是在医疗器械和元件上提供抗微生物涂层。许多医疗器械是由金属材料或聚合物材料制成的。这些材料通常具有高的摩擦系数。通常将具有低摩擦系数的低分子量材料混入材料主体或涂覆在基底表面上以有助于器械的功能性。
在过去35年间,通常实践的是将热塑性聚氨酯溶液用作抗微生物涂料的载体。溶剂通常为四氢呋喃(THF)、二甲基甲酰胺(DMF)或所述两者的共混物。因为THF能够非常快速被氧化且非常易于爆炸,所以需要昂贵的防爆涂覆设施。这些苛刻的溶剂也会攻击通常使用的许多聚合物材料,所述聚合物材料包括聚氨酯、有机硅、聚异戊二烯、丁基橡胶、聚碳酸酯、硬质聚氨酯、硬质聚氯乙烯、丙烯酸系材料和丁苯橡胶(SBR)。因此,由这些材料制成的医疗器械能够随时间而变形和/或在其表面上形成微裂缝。这种涂料的另一个问题是将溶剂完全热蒸发掉需要花费几乎24小时。因此,常规技术永远存在加工、性能和成本的问题。
另一个限制是合适的抗微生物试剂在这种涂料中的可用性。在涂覆医疗器械中所使用的最常用的抗微生物试剂是银。银盐和银元素在医疗外科行业和普通行业两者中都是熟知的抗微生物试剂。通常将其并入聚合物本体材料中或通过等离子体、热蒸发、电镀、或通过常规的溶剂涂覆技术将其涂覆在医疗器械表面上。这些技术冗长、昂贵且环境不友好。
另外,银涂覆的医疗器械的性能至多算作中等。例如,在由银盐或银元素的离子化而得到的银离子实现作为抗微生物试剂的功效之前,需花费高达八(8)小时。因此,在银涂层恰好发挥功效之前,大量的微生物活性也已发生。此外,银化合物或银元素具有从暗琥珀色到黑色的令人不悦的颜色。
因此,本领域中需要改进的组合物以为各种医疗器械、尤其是关于输液治疗的器械提供抗微生物能力。具体地,需要一种能够容易地施涂到由聚合物材料和金属构造的医疗器械上的有效的抗微生物涂料。还需要一种改良方法,以将这种抗微生物涂料涂覆到医疗器械上。
发明概述
针对本领域中通过目前可获得的抗微生物组合物和方法尚未完全解决的问题和需要,完成了本发明。因此,通过提供与医疗器械一起使用的抗微生物组合物和方法,开发了这些组合物和方法以减少诸如CRBSI的并发症的危险和几率。
本发明涉及具有抗微生物性能的紫外线(UV)(大约200nm~600nm的波长)可固化涂料。通过在上述范围内即约200nm~约600nm的光可将所述涂料固化。在某些实施方案中,优选利用约300nm~约450nm范围内的光将所述组合物固化。这些涂料特别适合用在医疗器械上,特别是像无针阀的血管内接入装置。如上所述,所述医疗器械通常有聚合物基材、尤其是聚碳酸酯(PC)、聚氨酯(PU)、聚氯乙烯(PVC)、丁苯橡胶(SBR)和丙烯酸系材料构成。
在本发明的一个方面中,利用UV可固化涂料(下文中有时称作“UV”涂料)对这种器械的表面进行涂覆,所述UV可固化涂料包含UV可固化的组合物和并入其中的其他成分例如均匀分布在其整个基体中的抗微生物试剂。所述抗微生物试剂能够扩散通过所述基体并杀死与所述涂层料表面接触的微观有机体。当通过IV流体将基体软化时,均匀分布在UV涂料基体中的抗微生物试剂逐渐从所述基体中扩散出去。然后,可利用抗微生物试剂将与涂料表面接触的微生物杀死。
本发明的制剂通常由聚氨酯或聚酯型低聚物与丙烯酸酯型官能团、丙烯酸酯型单体、光引发剂、流变改性剂和抗微生物试剂的组合构成。纳米级或微米级的抗微生物试剂颗粒均匀并永久地分布在整个涂料基体中。
所述涂料是无溶剂的且通过使用其他常规涂覆方法能够将其喷施、擦拭、浸渍或分布以涂覆到基底表面上。然后,利用紫外光将其快速固化。可在数秒或数分钟内使其完成固化,这取决于制剂和固化条件。本发明的涂料通常在数分钟内产生效用,而不像常规涂料在数小时后产生效用。所述涂料通常还具有令人舒适的浅颜色或者甚至是透明色。
在本发明的范围内,能够使用多种低聚物。仅需要所述低聚物能够进行UV固化且能够携带本文中所述类型的抗微生物试剂。例如,所述低聚物能够为丙烯酸改性的脂族聚氨酯、丙烯酸改性的芳族聚氨酯、丙烯酸改性的聚酯、不饱和聚酯、丙烯酸改性的聚醚、丙烯酸改性的丙烯酸系材料等、或上述物质的组合。所述丙烯酸改性的官能团能够为单官能、二官能、三官能、四官能、五官能或六官能的。
如同所述低聚物一样,在本组合物中能够使用多种单体。再次,仅需要总体组合物是UV可固化的且所述组合物能够携带抗微生物试剂。例如,所述单体能够为丙烯酸2-乙基己基酯、丙烯酸异辛酯、丙烯酸异冰片酯、1,6-己二醇二丙烯酸酯、二甘醇二丙烯酸酯、三甘醇二丙烯酸酯、季戊四醇四丙烯酸酯、季戊四醇三丙烯酸酯、二甲氧基苯基苯乙酮己基甲基丙烯酸酯、1,6-己二醇甲基丙烯酸酯等、或这些化合物的组合。
为了允许进行UV固化,所述组合物应具有足够的且相容的光引发剂。在本发明的特定实施方案中,所述光引发剂能够为:1)单分子分裂型,例如苯偶姻醚、苯乙酮、苯甲酰基肟和酰基氧化膦;和2)氢夺取型,诸如米蚩酮、噻吨酮、蒽醌(anthroguionone)、二苯甲酮、甲基二乙醇胺和2-N-丁氧基乙基-4-(二甲氨基)苯甲酸盐等、或这些物质的组合。
在特定实施方案中,优选向所述组合物中添加流变改性剂。所述流变改性剂使得可根据需要对所述组合物的流动特性进行控制和改进。所述流变改性剂还有助于抗微生物试剂和其他材料在所述组合物内的均匀分布。合适的流变改性剂可包括有机粘土、蓖麻蜡、聚酰胺蜡、聚氨酯和热解二氧化硅或这些物质的组合。
可将多种抗微生物试剂用于本发明的组合物中。仅需要所述抗微生物试剂与所述组合物的其他成分相容且其可有效地控制微生物试剂。具体地,优选的是,所述抗微生物试剂不会与组合物的其他成分发生化学反应。如上所述,在特定实施方案中,优选的是,所述抗微生物试剂能够在组合物的基体内发生移动,从而能够将其传送到微生物试剂的位置处。在本发明范围内的合适的抗微生物试剂的实例包括醛、N-酰苯胺、双胍、银元素或其化合物、双酚、和季铵化合物等、或上述物质的组合。
在另一个方面中,本发明可以是无溶剂的。如上所述,许多常规涂料使用苛刻的溶剂例如THF和DMF。可在不使用溶剂的条件下运行本发明,因此,本发明避免了因使用常规溶剂而带来的困难。
所述制剂对许多塑料表面(例如PC、PU、PVC、丙烯酸系材料和SBR)还显示了良好的粘附力。所述制剂能够被足够的紫外光(波长为大约200nm~600nm,且在特定实施方案中为约300nm~约450nm)所固化。
因此,本发明提供抗微生物涂料组合物,其克服了现有技术的许多限制。本发明使用被医疗用途所接受的已知成分。将这些成分合并并容易且高效地进行使用。如上所述,本发明的组合物通常包括低聚物、单体、光引发剂、流变改性剂和合适的抗微生物试剂。制得的组合物易于施涂到医疗器械的表面上并通过UV光快速固化。
