Catheter drainage of the wound; the process for draining fluid from a wound in a patient or deep closed to apply drugs the same; and a process for removing the catheter from the wound.
Catheter drainage of the wound; the process for draining fluid from a wound in a patient or deep closed to apply drugs the same; and a process for removing the catheter from the wound.
The wound drain catheter of the present invention is comprised of a drain portion connected to an outflow tube portion. The drain portion comprises a central core with plural T-shaped members projecting therefrom to form plural lumens having respective longitudinal grooves for fluid communication with the wound. This drain has a uniform cross-sectional area and is preferably made from a silicone elastomer having a durometer shore between 40 and 70 shore A. Such uniform cross-sectional area provides added strength to prevent the drain from breaking during its removal from the patient's body, and the silicone elastomer provides sufficient elasticity to permit the cross-sectional area of the drain to decrease by at least 30 percent when a pulling force is applied thereto, thereby reducing the gripping force of tissue surrounding the wound.
