摘要：
A continuous flushing catheter includes a valve comprising a relatively rigid central portion (24) and a flexible outer portion (19) surrounding said central portion (24). The valve has a sealing surface (26) which engages the central portion (24) around its whole circumference in liquid sealing relationship. A pair of integral lever arms transmit a shape-deforming force to the flexible outer portion (19) to lift a portion of the sealing surface (26) out of contact with the rigid cylinder (24), to permit passage of liquid through said valve.
