Description
技术领域
本发明涉及具有由硅橡胶形成的护套的医疗用线缆及其制造方法。
背景技术
以连接超声波诊断装置的主体和探头的探测线缆或在外科手术等中使用的内视镜线缆为代表的医疗用线缆中,采用由硅橡胶形成的护套。
由于硅橡胶是生物适合性(biocompatibility)的材料,所以通过采用由硅橡胶形成的护套,能够实现在外科用途或妇科用途等中也能够适当地使用的医疗用线缆。
另外,由于硅橡胶拨水拨油性和防污性高,所以通过采用由硅橡胶形成的护套,即使血液或者其他的污物附着于护套也能够容易擦拭除去。
另外,硅橡胶对于酒精或其它的消毒液的耐药性或者耐热性高,另外,即使实施等离子体杀菌或高压杀菌等的杀菌处理,也几乎不产生劣化,因此最适合于频繁地进行消毒或杀菌处理的医疗用途。
但是,硅橡胶整面地附着在表面,采用由硅橡胶形成的护套的医疗用线缆,在使用时或者收纳时的处理时,会较强地圈结而容易缠在一起,因此存在操作性和收纳性较差这样的课题。

用于解决问题的技术方案
本发明是为了达成上述目的而完成的,本发明的医用线缆包括:线缆芯线;在上述线缆芯线的周围形成的护套;和在上述护套的周围形成的保护膜,上述护套由硅橡胶形成,上述保护膜为将氟树脂和硅树脂混合而得到的树脂层。
优选上述保护膜的厚度为10μm以上50μm以下。
优选上述保护膜以比所述护套的额定温度低的温度烘烤形成。

发明效果
根据本发明,能够提供一种医疗用线缆及其制造方法,其能够减轻由硅橡胶构成的护套的圈结,提高操作性和收纳性。
附图说明
图1是表示本发明的医疗用线缆的截面示意图。
附图标记的说明
100医疗用线缆,101线缆芯线,102护套,103保护膜,104中间芯材,105线缆单元,106编织保护罩,107同轴线缆,108信号传输用单元,109绝缘线缆,110电源供给用单元,111固定带。
具体实施方式
以下参照附图依次说明本发明的优选的实施方式。
如图1所示,本发明的优选的实施方式的医疗用线缆100例如是连接超声波诊断装置的主体和探头的探测线缆,包括:线缆芯线101;在线缆芯线101的周围形成的护套102;和在护套102的周围形成的保护膜103。
线缆芯线101包括:中间芯材(tension member:承拉构件)104;以中间芯材104为中心而绞合的多个线缆单元105;和在多个线缆单元105的周围形成的编织保护罩106。
中间芯材104是用于,通过将多个线缆单元105以在线缆截面中排列成同心圆状的状态绞合,能够维持线缆芯线101的对称性而能够分散外力,从而提高线缆芯线101的耐折曲性、耐扭曲(缠绕)性和可弯曲性。
作为中间芯材104,为了提高相对于施加在线缆长度方向上的张力等的耐性,例如,能够举例芳族聚酰胺(aramid)等的聚酰胺类纤维、聚对苯二甲酸乙二醇酯等的聚酯类纤维形成的抗拉伸力纤维。
作为线缆单元105,能够举例集合多个同轴线缆107而形成的信号传输用单元108和集合多个绝缘线缆109而形成的电源供给用单元110。
在这些线缆单元105的周围一并卷绕有固定带(胶带)111,将多个线缆单元105维持成在线缆截面中排列成同心圆状的绞合形状。
护套102由硅橡胶形成,如上所述,兼具生物适合性(biocompatibility)、拨水拨油性、防污性和耐药性。
保护膜103为将氟树脂和硅树脂混合而得到的树脂层,其厚度尽可能在10μm以上50μm以下的程度。
更具体而言,例如,使用在比护套102的额定温度低的温度下挥发的挥发性有机溶剂,将在该挥发性有机溶剂中溶解氟树脂而得到的氟油和在该挥发性有机溶剂中溶解硅树脂而得到的硅油混合,制成混合液,将其涂敷在护套102的周围之后,以比护套102的额定温度低的温度(例如40℃以上80℃以下)进行烘烤,使混合液中含有的挥发性有机溶剂挥发,由此,在护套102的表面不可避免地存在的细微粗糙面上固定了氟树脂和硅树脂混合而成的氟硅覆膜,形成非常薄的保护膜103,从而制造医疗用线缆100。
此外,作为挥发性有机溶剂,在使用了在常温下挥发的常温挥发性有机溶剂的情况下,在将混合液涂敷在护套102的周围之后,使其自然干燥而将混合液中所含的挥发性有机溶剂挥发,由此在护套102的周围形成保护膜103。
但是,在医疗用途中,由于要除去医疗用线缆100的表面所附着的血液或其他的污物,需要频繁地擦拭医疗用线缆100的表面,因此,与其它的用途相比较,保护膜103容易剥离。
对于这一点,在医疗用线缆100中,由于以比护套102的额定温度低的温度进行烘烤而形成保护膜103,因此,与只通过自然干燥形成保护膜103的情况相比,能够使氟硅覆膜更加牢固地附着在护套102的表面,所以能够得到不易发生剥离的、能够充分耐受频繁的擦拭的保护膜103。
由于氟成分有助于赋予滑性和耐磨耗性,所以通过采用含氟成分的保护膜103,对医疗用线缆100赋予滑性和耐磨耗性,能够减轻硅橡胶形成的护套102的圈结,能够提高医疗用线缆100的操作性和收纳性。
此外,从对医疗用线缆100赋予滑行和耐磨耗性的观点而言,考虑对护套102的周围挤出氟树脂而包覆护套102来形成保护层,但是氟树脂硬度高,另外,通过挤出包覆来形成保护层比较困难,所以当通过挤出包覆来形成保护层时,医疗用线缆100的柔软性和可弯曲性降低。
另外,由于氟树脂密接性低,即使通过挤出包覆形成保护层,也不能使保护层与护套102密接,在护套102与保护层的界面产生间隙,并且有可能产生成为对保护层造成皲裂等的损伤的原因的外表鼓起等。
相对于此,在医疗用线缆100中,如上所述,在护套102的表面不可避免地存在的细微的粗糙面上固定有氟硅覆膜,形成了非常薄的保护膜103,因此不仅能够使医疗用线缆100的柔软性和可弯曲性不降低,还能够对医疗用线缆100赋予滑性和耐磨耗性。
并且,由于能够使保护膜103密接于护套102,因此即使频繁地擦拭除去在医疗用线缆100的表面附着的血液和其他的污物,保护膜103也难以从护套102剥离,能够抑制在护套102与保护膜103的界面产生间隙,抑制产生成为对保护层103造成皲裂等的损伤的原因的外表鼓起等。
另外,由于氟树脂的熔点高,当通过挤出包覆形成保护层时,护套102暴露在250℃以上的高温中而发生热劣化,有可能产生由护套102所起到的医疗用线缆100的各种特性的降低。
相对于此,在医疗用线缆100中,如上所述,在将混合液涂覆在护套102的周围之后,以比护套102的额定温度低的温度进行烘烤来使包含在混合液中的溶剂挥发,由此在护套102的表面形成保护膜103,因此护套102不需要暴露在250℃以上的高温中而发生热劣化,能够防止医疗用线缆100的各种特性降低。
另外,保护膜103厚度为10μm以上50μm以下,更优选为30μm以上40μm以下,因此不需要使医疗用线缆100的外径大幅增加,能够对医疗用线缆100赋予滑性和耐磨耗性。另外,保护膜103的氟树脂与硅树脂的混合比率优选在8∶2至5∶5的范围中,更优选为7∶3。为了得到该混合比率,通过调整溶解有氟树脂的氟油与溶解有硅树脂的硅油的混合比例即可。
如上所述,根据本发明,提供一种医疗用线缆及其制造方法,能够减轻硅橡胶形成的护套的圈结,提高操作性和收纳性。
