VACUUM AND POSITIVE PRESSURE VENTILATION SYSTEMS AND METHODS FOR INTRATHORACIC PRESSURE REGULATION
First Claim
Patent Images
1. An intrathoracic pressure regulator system for use in treating a patient, the system comprising:
- a patient port that fluidly communicates with the patient;
a ventilator port that fluidly communicates with a ventilator mechanism for facilitating a positive pressure ventilation procedure administered to the patient via the patient port;
a vacuum port that fluidly communicates with a vacuum mechanism for facilitating a vacuum procedure administered to the patient via the patient port; and
a valve for controlling fluid flow, wherein during administration of the positive pressure ventilation procedure the valve allows fluid flow between the ventilator port and the patient port and inhibits fluid flow between the vacuum port and the patient port, and during administration of the vacuum procedure the valve inhibits fluid flow between the ventilator port and the patient port and allows fluid flow between the vacuum port and the patient port.

Abstract
Medical techniques include systems and methods for administering a positive pressure ventilation, a positive end expiratory pressure, and a vacuum to a person. Approaches also include treating a person with an intrathoracic pressure regulator so as to modulate or upregulate the autonomic system of the person, and treating a person with a combination of an intrathoracic pressure regulation treatment and an intra-aortic balloon pump treatment.

6. An intrathoracic pressure regulator system for use in treating a patient, the system comprising:
-
a processor that accepts an operator selection input that designates a member selected from the group consisting of a circulatory assist mode, a ventilation mode, and a continuous positive airway pressure mode; and a manifold assembly in operative association with the processor, the manifold assembly comprising; an oxygen inlet port in fluid communication with an inspiratory plane, wherein the oxygen inlet port receives oxygen from an oxygen source; an air inlet port in fluid communication with the inspiratory plane, wherein the air inlet port receives air from an air source; an expiratory gas outlet port in fluid communication with an expiratory plane, wherein the expiratory gas outlet port allows expired gas to pass therethrough toward a negative pressure mechanism; a patient circuit interface having an inspiratory lumen that transmits air and oxygen toward the patient and an expiratory lumen that transmits expired gas away from the patient; an inspiratory control valve assembly that controls fluid flow between the inspiratory plane and the inspiratory lumen; and an expiratory control valve assembly that controls fluid flow between the expiratory plane and the expiratory gas outlet port; a fixed or adjustable negative pressure mechanism that delivers a negative pressure treatment to the patient via the expiratory lumen when the system is in a circulatory assist mode; and a member selected from the group consisting of a positive pressure ventilation mechanism that delivers a positive pressure ventilation treatment to the patient via the inspiratory lumen when the system is in a ventilation mode, and an adjustable continuous positive airway pressure mechanism that delivers an adjustable continuous positive airway pressure treatment to the patient via the expiratory lumen when the system is in a continuous positive airway pressure mode. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method of providing an intrathoracic pressure regulation treatment to a patient that is suffering from or at risk of developing sepsis, shock, heart failure, cardiac arrest, acute respiratory distress syndrome, polytrauma, head disease, elevated hepatic or portal vein pressures, bleeding during abdominal, head and neck surgery, or insufficient circulation during open heart surgery, the method comprising:
-
administering a positive pressure ventilation generated by a ventilator mechanism to the person'"'"'s airway via a patient port of an intrathoracic pressure regulator system; and administering a vacuum generated by a vacuum mechanism to the person'"'"'s airway via the patient port of the intrathoracic pressure regulator system; wherein during administration of the positive pressure ventilation a fluid control valve of the intrathoracic pressure regulator system allows fluid flow between the ventilator mechanism and the patient port and inhibits fluid flow between the vacuum mechanism and the patient port, and during administration of the vacuum the fluid control valve of the intrathoracic pressure regulator system inhibits fluid flow between the ventilator mechanism and the patient port and allows fluid flow between the vacuum mechanism and the patient port. - View Dependent Claims (14, 15, 16)

-
administering a fixed or adjustable negative pressure treatment to the patient via an expiratory lumen of an intrathoracic pressure regulator system when the system is in a circulatory assist mode; and administering a positive pressure ventilation treatment to the patient via an inspiratory lumen of the intrathoracic pressure regulator system when the system is in a ventilation mode, or administering an adjustable continuous positive airway pressure treatment to the patient via the expiratory lumen of the intrathoracic pressure regulator system when the system is in a continuous positive airway pressure mode. - View Dependent Claims (18, 19, 20, 21, 22)
