  • Publication number: 20040267305
    Abstract: Flexible tube contents removers that are particular suitable for a variety of medical procedures include spaced arms supporting a pair of parallel spaced tapered rollers having spacing that is adjustable through finger pressure. One embodiment has the flexible tube extending through a hole in one support arm that directs the tube between the rollers. Another embodiment includes the rollers at an angle to a line normal to the longitudinal axis of the support arm so the tube extends along one side of the support arms and between the rollers. Stop surfaces restrict movement of the arms beyond a selected acute inside angle. A cam surface and resilient cut-out section on the arms serves as a bias to return the arms to a position of maximum spacing for the rollers when the finger pressure is removed.
