DEVICES AND METHODS FOR DELIVERY OF A THERAPEUTIC AGENT THROUGH A PNEUMOSTOMA

摘要

A pneumostoma management system includes a pneumostoma management device for maintaining the patency of a pneumostoma and a drug delivery device for pneumostoma care. The drug delivery device includes a therapeutic agent dispenser for supplying a therapeutic agent and a propellant at positive pressure, a tube for entering the pneumostoma and a limiting device for limiting the depth of insertion of the tube into a pneumostoma. The drug delivery device may be used to introduce therapeutic agents into the pneumostoma for direct treatment of the pneumostoma, treatment of the lung by way of collateral ventilation, and/or treatment of non-lung tissues by diffusion into the bloodstream.
