Description
技术领域
本发明涉及一种电气技术，尤其是一种防静电技术，具体地说是一种降低OCT设备整机接地电阻的连接件。
背景技术
目前，血管内断层成像系统配合成像导管设计用于对直径＞1.5mm的血管的成像，实现对管腔直径、面积的精确测量，对血管壁及血管内植入物结构的成像，进而辨别斑块性质和用于血管内植入物（支架、滤器、弹簧圈等）的评价。
血管内断层成像系统是基于血管内光学相干断层成像（Optical CoherenceTomography，OCT）技术结合成像导管的系统，OCT技术作为继血管内超声（IntravascularUltrasound，IVUS）后出现的一种新的冠状动脉内成像技术，与IVUS相比，OCT极高的分辨率使其在评价易损斑块、指导支架植入，尤其是在急性冠脉综合征（Acute CoronarySyndrome，ACS）诊疗中的应用日益受到关注。
2011年，美国心脏病学会/美国心脏协会（ACCF/AHA）冠状动脉介入指南中对IVUS在经皮冠状动脉介入治疗（Percutaneous Coronary Intervention，PCI）中应用的推荐等级为IIa，而对OCT的推荐等级因循证医学证据不足尚未确立。2012年，CLI-OPCI研究表明，与单纯造影指导的PCI治疗相比，OCT指导下的PCI治疗可显著改善患者预后。随后，在2013年欧洲心脏病学会关于稳定型冠心病管理指南中，OCT对于评估病变特征及优化支架植入过程均列为IIb级推荐（证据水平为B级），总体证据水平等同于IVUS。2014年，欧洲心脏病学会/欧洲心胸外科协会（ESC/EACTS）心肌再血管化指南中，将OCT对优化PCI的推荐等级提升到与IVUS等同的IIa级推荐。2015年发表的ILUMIEN I研究表明PCI术前和/或术后行OCT检查可影响术者的介入治疗策略。ILUMIEN II研究结果表明OCT 在指导支架膨胀方面不劣于IVUS。随着 OCT 技术的不断更新和更多前瞻性研究数据的公布，OCT在冠心病介入诊疗领域中的地位必将进一步提升。
OCT设备是一种精密仪器，根据医疗器械的相关规定，设备在出厂前必须进行静电试验，一方面要防止外界静电对内部设备的干扰破坏，防止影响设备的运行精度，另一方面还要防止设备使用过程中产生的静电对医疗环境的影响，防止其对其它精密设备的干扰和破坏。而据申请人所知，目前的OCT设备在设计阶段均未充分考虑到静电影响，也没有较好的方法来解决静电电荷的积聚问题，经常导致静电检测不合格，为此，申请人设计一种通过铜皮连接的技术方案，较好地解决了这一问题，但由于铜皮是通过导电胶与金属组件相连的，导电胶的连接和导电性能受温度影响较大，会影响整机的接地电阻，必须加以改进。
发明内容
本发明的目的是针对现有的OCT设备解决静电电荷积聚用的导电胶存在受环境温度影响较大，可靠性差的问题，发明一种降低OCT设备整机接地电阻的连接件。
本发明的技术方案是：
一种降低OCT设备整机接地电阻的连接件，其特征是它主要由金属连接块1和金属导电编织带2组成，所述的金属导电编织带2的两端分别与对应的金属连接块1相连，在金属连接块1上设有穿装紧固件的光孔或螺孔3。
所述的金属导电编织带2的两端压装或焊接在金属连接块1的卡槽中。
在金属连接块1与被连接组件之间加装有弹性垫片4。
所述的弹性垫片4由海棉和包裹在海棉表面的导电金属丝网组成，在与所述光孔或螺孔3位置相对处加工有相匹配的通孔。
本发明的有益效果：
本发明结构简单，连接可靠，不受环境因素影响，尤其是采用导电泡棉作为垫片解决了金属连接块与组件金属面板之间的连接电阻，实现了可靠连接，使接地电阻接近0，导通性好。
附图说明
图1是本发明的结构示意图。
图2是本发明的泡棉的结构示意图。
具体实施方式
下面结合实施例对本发明作进一步的说明。
如图1-2所示。
一种降低OCT设备整机接地电阻的连接件，其特征是它主要由金属连接块1和金属导电编织带2组成，所述的金属导电编织带2的两端分别与对应的金属连接块1相连，在金属连接块1上设有穿装紧固件的光孔或螺孔3。所述的金属导电编织带2（可采用铜丝编织，也可用铜丝束来代替）的两端最好是通过压装或焊接在金属连接块1的卡槽中，如图1所示，具体实施时，为了提高金属连接块1与金属组件之间的连接电阻，可在金属连接块1与被连接组件之间加装有弹性垫片4。所述的弹性垫片4最好采用由海棉6和包裹在海棉表面的导电金属丝网5的泡棉结构，为了使用方便，在与所述光孔或螺孔3位置相对处加工有相匹配的通孔。
使用时，用螺钉将金属连接块及泡棉固定在被连接面上即可。
本发明未涉及部分均与现有技术相同或可采用现有技术加以实现。
