ABSTRACT:
A drainage tube has a main body portion in which the distal or bottom end has an arch-like cross-section such that the distal end provides a protective shield to prevent blockage of the fluid inlet opening at the proximal or front end of the main body portion. An elongated slot-like drainage channel extends through the main body portion from the fluid inlet to a discharge opening at the distal end and assumes the same general convex-arch-like configuration as the main body portion. A flexible flange extends radially outwardly from the fluid inlet and a hollow stem member extends from the discharge opening in the distal end and provides an extension of the drainage channel. The stem also prevents the drainage tube from falling through the access in the body wall into the body cavity while the flange prevents the tube from being accidentally pulled out of the body cavity. A cut-out portion on the side of the stem opposite the flange member can be provided to form an access and guide for a probe to be inserted into the body cavity through the drainage channel.
