Surgical wound drain device

摘要

This invention provides a surgical wound drain device which is adapted for postoperative multiphasic suction withdrawal of physiological fluids and coagulated solids and tissue debris from a wound cavity in a closed drainage system. The drain device consists of an inner catheter member, and an outer tubular member which has one or more thin pliable strips extending form the distal end periphery. The catheter withdraws accumulated body fluids in a postoperative first stage. The catheter is removed, and the remaining outer tubular member with its extended pliable strips is adapted to withdraw body fluids and coagulated solids and tissue debris in a second stage over an extended period.
