[0001] 本发明涉及医疗器械技术领域，公开了一种脓胸伴瘘引流装置，包括导管组件，包括导管远端和导管本体，导管远端置入脓腔内，导管远端的外壁上依次开设有排液孔及排气孔。本发明通过将排液孔设于腔底区域、排气孔设于瘘口区域，并在两者之间设置可充气膨胀的隔离气囊，在脓液积聚区与瘘口气体区之间形成物理隔离屏障，阻断气流对排液区的干扰，解决气液混流导致的引流不畅问题，导管本体内设相互独立的排脓腔、排气腔、换药腔及气囊隔离腔，实现气液分流独立引流，避免气体占据引流通道影响脓液排出，换药腔连接的冲洗喷口可在不拆卸主引流通路的情况下向脓腔注入药液，完成清洁给药，降低污染风险，从而能够满足脓胸伴瘘患者的长期引流管理需求。
