支气管肺泡灌洗及肺脓腔灌洗注药用球囊导管
:本技术属于医疗辅助器械
,具体涉及一种支气管镜介入诊疗时行支气管肺泡灌洗及对肺脓腔的灌洗注药用的球囊导管。
技术介绍
:支气管肺泡灌洗术是通过支气管镜对支气管以下肺段或亚肺段水平,注入无菌生理盐水、并随即抽吸,收集肺泡表面衬液,检查其细胞成分和可溶性物质的一种方法。支气管肺泡灌洗能直接获取肺内炎症免疫效应细胞,是探讨肺局部免疫病理过程的一种比较安全和有用的检查方法,主要用于有关疾病的临床诊断领域。肺脓肿是临床上常见的由多种病原菌引起肺组织坏死性液化,继而形成脓肿、脓腔的肺部疾病,支气管镜可在直视下对支气管所属的肺脓腔区进行局部灌洗和注入药液,并引流脓液,提高治愈率,缩短患者治疗时间,故支气管镜可应用于肺脓肿等肺脓腔病的治疗领域。目前,支气管肺泡灌洗术及对肺脓肿等肺脓腔疾病的支气管镜介入治疗术两者操作中的关键均在于将支气管镜顶端紧密楔入段或亚段支气管开口处,两者均是经支气管镜工作孔通过硅胶管快速注入适量37℃灭菌生理盐水,随后两者均是退出硅胶管后立即负压吸引回收灌洗液。然而,在长期的临床实际操作中发现,两者在操作过程 ...
