Aspirator for pneumostoma management
First Claim
1. A device for treating a pneumostoma which comprises a surgically-created aperture which passes through a chest wall of a patient and into a lung of a patient without communicating with a pleural cavity of the patient and which enables gases to exit the lung through the chest wall of the patient, the device comprising:
- a tube shaped for insertion into the pneumostoma, the tube having sufficient length that upon insertion into the pneumostoma, a proximal end of the tube is positioned exterior to a patient and a distal end of the tube is positioned within the lung of the patient;
an aperture adjacent the distal end of the tube, the aperture sized and positioned to allow ingress of liquid and solid discharge from a lung;
a lumen passing from the aperture to the proximal end of the tube;
a flange projecting from the proximal end of the tube, the flange sized to prevent passage of the flange into the pneumostoma and thereby limit insertion of the tube into the lung; and
a suction device connected to the proximal end of the tube such that, with the tube positioned in a pneumostoma and the flange positioned against the chest wall of the patient, actuation of the suction device applies negative pressure to the lumen at the proximal end of the tube and draws liquid and solid discharge from the lung into the lumen through the aperture adjacent the distal end of the tube.

Abstract
A pneumostoma management system includes a pneumostoma management device for maintaining the patency of a pneumostoma while controlling the flow of material through the pneumostoma and a pneumostoma aspirator for pneumostoma care. The pneumostoma aspirator includes a bulb or syringe for applying positive or negative pressure, a tube for entering the pneumostoma and a limiting device for limiting the depth of insertion of the tube into a pneumostoma. The pneumostoma aspirator may also be used to introduce irrigation fluid into the pneumostoma and/or remove irrigation fluid and discharge from the pneumostoma.

12. A medical device for treating a pneumostoma which comprises a surgically-created aperture which passes through a chest wall of a chest of a patient and into a lung of a patient without communicating with a pleural cavity of the patient and which enables gases to exit the lung through the chest wall of the patient, the medical device comprising:
-
a flange sized and configured such that the flange cannot be inserted into the pneumostoma, the flange positioned to engage the chest of the patient; a tube projecting from the flange, the tube configured such that, with the flange engaging the chest of the patient, the tube is positioned in the pneumostoma such that a proximal end of the tube is external to the patient and a distal end of the tube is positioned within the lung of the patient; a lumen extending along the tube from the proximal end of the tube; at least one aperture communicating with the lumen, the at least one aperture positioned such that, with the flange engaging the chest of the patient, the at least one aperture is positioned within the lung of the patient; and a suction device connected to the proximal end of the tube such that, with the at least one aperture positioned within the lung of the patient, actuation of the suction device applies negative pressure to the lumen at the proximal end of the tube and draws liquid and solid discharge from the lung into the lumen through the at least one aperture. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)

21. A system for treating a pneumostoma which comprises a surgically-created aperture which passes through a chest wall of a chest of a patient and into a lung of a patient without communicating with a pleural cavity of the patient and which enables gases to exit the lung through the chest wall of the patient, the system comprising:
-
a pneumostoma management device which includes, a flange sized and configured such that the flange cannot be inserted in the pneumostoma, the flange positioned to engage the chest of the patient, a tube projecting from the flange, the tube configured such that, with the flange engaging the chest of the patient, the tube is positioned in the pneumostoma such that a proximal end of the tube is external to the patient and a distal end of the tube is positioned within the lung of the patient, a lumen extending along the tube from the proximal end of the tube, and an aperture communicating with the lumen, the aperture positioned such that, with the flange engaging the chest of the patient, the aperture is positioned within the lung of the patient; and a pneumostoma aspirator which includes, a coupling configured to releasably secure the pneumostoma aspirator to the pneumostoma management device; and a suction device connected to coupling such that, with the aperture positioned within the lung of the patient and the coupling releasably secured to the pneumostoma management device, actuation of the suction device applies negative pressure to the lumen at the proximal end of the tube and draws liquid and solid discharge from the lung into the lumen through the aperture. - View Dependent Claims (22, 23, 24, 25)
