ABSTRACT:
A method and apparatus for conveying fluids includes tubing and a tube clearing sleeve surrounding the tubing. The sleeve has a slick inner surface with a coefficient of friction less than that of the outer surface of the tubing. The sleeve is compressed between the fingers to compress the tubing and the compressed sleeve is advanced along the tubing to displace contents in the tubing.
