Pneumostoma management system with secretion management features for treatment of chronic obstructive pulmonary disease
First Claim
1. A pneumostoma management device adapted to allow gases to exit a lung through a pneumostoma in a chest of a patient, wherein the pneumostoma management device comprises;
- a tube adapted to be inserted into the chest through the pneumostoma, the tube having a lumen, a proximal end and a distal end, the distal end of the tube having at least one opening adapted to admit gases from the lung;
a flange connected to the proximal end of the tube such that an opening in the flange connects to the lumen of the tube, the flange projecting a sufficient distance from the tube to preclude passage of flange into the pneumostoma;
a filter disposed over the opening in the flange and secured to one of the flange and tube such that gases passing into and out of the lumen of the tube pass through the filter; and
one or more secretion management features adapted to trap non-gaseous discharge within the pneumostoma management device.

Abstract
A flexible pneumostoma management device maintains the patency of a pneumostoma while controlling the flow of material through the pneumostoma. The pneumostoma management device includes a pneumostoma vent having a tube which enters the pneumostoma to allow gases to escape the lung, a flange and a filter/valve to control flow of materials through the tube. The flange is a thin flexible patch which conforms and attaches to the chest of the patient. The flange secures the tube in position in the pneumostoma. The device has features to control secretions from the pneumostoma. The secretion management features include, ridges, pores, absorbent materials, and combinations thereof.

8. A medical device adapted to allow gases to exit a lung through a pneumostoma in a chest of a patient, wherein the medical device comprises;
-
a substantially planar flange having a contact surface adapted to contact the chest of the patient and an outer surface, the flange having a substantially central opening; a tube projecting substantially perpendicular to the flange, the tube adapted for insertion into the chest through the pneumostoma, the tube having a lumen, a proximal end and a distal end, the distal end of the tube having an atraumatic tip, the distal end of the tube having at least one opening adapted to admit gases from the lung, the proximal end of the tube being connected to the flange such that the opening in the flange communicates with the lumen of the tube; a filter disposed over the opening in the flange and secured to one of the flange and tube such that gases passing into and out of the lung pass through the filter; and one or more secretion management features adapted to trap non-gaseous discharge within the pneumostoma management device. - View Dependent Claims (9, 10, 11, 12, 13, 14)
