First Claim
Patent Images
1. A ventilation bypass system to assist exit of air from a lung of a subject through a wall of a chest of the subject wherein the ventilation bypass system comprises:
- a ventilation control device adapted to be located on the chest of the subject;
the ventilation control device having a generally-planar surface adapted to contact skin of a chest of a patient;
a conduit which protrudes from the generally-planar surface of the ventilation control device said conduit having a distal end adapted to be passed through the wall of the chest of the subject wherein the length of the conduit is such that when the generally-planar surface of the ventilation control device is in contact with the skin of the chest of the patient, the distal end of the conduit is positioned within the parenchymal tissue of the lung; and
a chest tube adapted to evacuate air from a pleural space around the lung wherein the chest tube is associated with the conduit and oriented so that when the distal end of the conduit is positioned within the parenchymal tissue of the lung an open end of the chest tube is positioned in the pleural space of the subject.

Abstract
A collateral ventilation bypass system with chest tube evacuation device may be utilized in combination to removed trapped air from the lungs. With the chest tube evacuation device, any air trapped in the pleural space may be evacuated through the bypass system to prevent a pneumothorax.

13. A ventilation bypass system comprising:
-
a ventilation control device having a one-way valve which allows gasses to exit a lung and prevents gasses from entering the lung via the one-way valve; a first conduit having a proximal end coupled to the ventilation control device, and a distal end adapted to be positioned through a chest wall of a patient into parenchymal tissue of a lung of the patient; whereby the first conduit enables gasses to exit the lung of the patient through the chest wall of the patient into the ventilation control device bypassing a trachea of the patient, but said first conduit is prevented, by the ventilation control device, from allowing gases to enter the lung of the patient through the chest wall; a second conduit associated with the first conduit so that the first conduit and second conduit are adapted to be passed through a single port in the chest wall of the patient; the second conduit having a distal end; wherein the distal end of the second conduit is oriented in a different direction than the distal end of the first conduit such that, with the distal end of the first conduit positioned through a chest wall of a patient into parenchymal tissue of a lung of the patient, the distal end of the second conduit is adapted to be positioned through the chest wall of the patient into a pleural space; and whereby the second conduit enables gasses to exit the pleural space of the patient through the chest wall of the patient. - View Dependent Claims (14, 15, 16, 17, 18)

19. A medical device for insertion in an opening in a chest wall of a patient wherein the opening passes through a chest wall, parietal membrane, pleural cavity and visceral membrane into parenchymal tissue of a lung of the patient and wherein the medical device comprises:
-
an external component, wherein the external component has a generally-planar surface adapted to contact skin of a chest of a patient; a conduit having a distal end which protrudes from the generally-planar surface of the external component and wherein the conduit has a length such that when the generally-planar surface of the external component is in contact with the skin of the chest of the patient, the distal end of the conduit is positioned within the parenchymal tissue of the lung and gases within the parenchymal tissue can exit the lung via the conduit; an evacuation device which protrudes from the conduit, in a different direction than the distal end of the conduit;
at a position spaced from the contact surface of the external component and spaced from the distal end of the conduit such that, when the distal end of the conduit is positioned within parenchymal tissue of the lung, the evacuation device is positioned in the pleural cavity between the visceral membrane and the parietal membrane whereby the evacuation device enables gasses to exit the pleural cavity of the patient through the opening in the chest wall of the patient. - View Dependent Claims (20, 21, 22, 23, 24)
