ABSTRACT:
A drainage device used in the body cavity comprising a flexible metallic guide wire capable of being inserted into a puncture needle, a tube-like dilator made of slightly hard synthetic resin and covering the outer periphery of the guide wire, a drainage tube made of synthetic resin in which a wire is embedded and covering the outer periphery of the guide wire, a sheath made of synthetic resin having a total length shorter than that of the dilator and having at a proximal portion of the sheath a fastening plug to be liquidtightly connected to a fastening jack of the dilator, and a universal fastening jack to be detachably attached to an end of the drainage tube and to be liquidtightly connected to the fastening plug.
The draingage device can simplify the insertion of the drainage tube and shorten the time required for manual drainage operation.
