用于多腔导管的流体输入模块

Fluid input module for multi-lumen catheters
Abstract:
A cleaning catheter (200) includes fluid-delivery and suction lumens (520, 530). A flow regulator (700) defines suction and fluid ports (830, 827). A mechanical user control element (320) is configured to mechanically and non-electrically set activation states of the flow regulator (700), and transition between first and third configurations via a second configuration. When the control element (320) is in the first configuration, the flow regulator (700) blocks fluid communication (a) between the suction port (830) and the suction lumen (530) and (b) between the fluid port (827) and the fluid-delivery lumen (520). When the control element (320) is in the second configuration, the flow regulator effects fluid communication between the suction port (830) and the suction lumen (530), and blocks fluid communication between the fluid port (827) and the fluid-delivery lumen (520). When the control element (320) is in the third configuration, the flow regulator (700) effects fluid communication (a) between the suction port (830) and the suction lumen (530) and (b) between the fluid port (827) and the fluid-delivery lumen (520).
Abstract(Chinese):

清洁导管（200）包括流体输送和抽吸腔（520,530）。 流量调节器（700）限定抽吸和流体端口（830,827）。 机械用户控制元件（320）被配置为机械地和非电气地设置流量调节器（700）的启动状态，以及经由第二配置在第一和第三配置之间转换。 当控制元件（320）处于第一配置时，流量调节器（700）阻止吸入口（830）和吸入腔（530）之间的流体连通（a）和（b）流体端口（827） 和流体输送腔（520）。 当控制元件（320）处于第二配置时，流量调节器实现吸入口（830）和吸入腔（530）之间的流体连通，并阻止流体端口（827）和流体输送 内腔（520）。 当控制元件（320）处于第三构造时，流量调节器（700）在吸入口（830）和吸入腔（530）之间实现流体连通（a）和（b）在流体端口（827） 和流体输送腔（520）。
