ABSTRACT:
A drainage tubing for wounds, or body cavities, is described. The tubing is placed and retained in the wound site in an improved manner by means of an inflatable balloon positioned in the intact, healthy tissue adjacent the patient's skin, or in the body cavity adjacent a wall thereof. The drainage tubing may also have a second, collapsible bulb portion for aseptic back-flushing of the placement site while the tubing lumen is sealed from the exterior. The specific construction enables a technician to insert the tubing when used in a wound site either from within or without the placement site using an awl to penetrate the exterior tissue adjacent the site.
