ABSTRACT:
A connector that permits safe and convenient attachment of a wound drainage tube to a fluid reservoir includes a hollow penetrator whose one end is attachable to the drainage tube and whose other end is sharpened to permit it to pierce a penetrable plug that initially seals an inlet tube of the reservoir. The penetrator is covered with a stocking that initially prevents fluid from flowing out of the sharpened end. A protective skirt has one end attached to the penetrator. Its other end is open and permits the skirt to surround the inlet tube as the penetrator is moved toward the plug and then pierces the stocking and plug to permit fluid to flow from the drainage tube to the reservoir.
