血管闭合器简介

Brief introduction of vascular closure device

血管闭合器是经皮血管穿刺后用于穿刺点止血的医疗器械,根据其原理大致可分为主动血管闭合器、压迫辅助闭合器及表面止血贴。它们可缩短介入治疗术后止血时间、制动时间及住院时间,减少患者创伤,提高患者舒适度,同时亦减轻医护人员工作负担。但每款闭合器均有其适用范围及学习曲线等,应用不当可能导致严重并发症,因此介入医师在采用闭合器前应熟知其特点并掌握常见并发症处理。本文综合闭合器厂家资料及近年相关研究文献,就数款常见血管闭合器原理、特点、适用范围及使用技巧等作一简单介绍。

A vascular closure device（VCD） is a medical apparatus which is used for stopping bleeding at the puncture point after percutaneous vascular puncturing management. According to its principles, these devices can be categorized into active closure device, compression-assisted device and local hemostatic plaster. The use of these devices can shorten the time of hemostasis, the time of limb immobilization, and the time of hospitalization; it can also reduce the damage to the patient, improve patient＇s comfort, and reduce the work load of the medical staff as well. But each VCD has its own applicable scope and learning curve,thus it might cause serious complications when it is improperly used. Therefore, in using VCD the interventional physicians should be familiar with the characteristics of each special VCD and have enough knowledge concerning the treatment of the common complications. This paper aims to make a comprehensive review of the closure device manufacturer data and the relevant literatures recently published so as to make a brief introduction of the principle, characteristics, scope of application and practical tips of several common vascular closure devices.
