Reinforced Therapeutic Tube.

摘要

Reinforced therapeutic tubes are disclosed. At least one of the tips of the spiral shape reinforcing material (6) is bent back inward of the tube (4) to a length such that it is engaged onto at least a neighboring spiral turn, and moreover, at least the tip (9) of the reinforcing material (6) bent is buried into the tube wall; for this reason, there is no fear of the tip of the reinforcing material (6) breaking through the tube wall, and even if external force is imposed onto the tube (4), the tube (4) will not be kinked, and thus, its roundness will be maintained at all times.
