Breathing-Gas Delivery And Sharing System And Method
First Claim
1. A patient respiration isolation device, comprising:
- a movable partition having an actuating side on a first side of the movable partition, and a patient side on a second side of the movable partition;
a housing disposed about the movable partition, the housing having an ventilator orifice adaptable to be in pneumatic communication with a ventilator;
an inlet pressure regulator in fluid communication with the actuating side of the movable partition; and
an exhaust pressure regulator capable of controlling a positive-end-of-expiration pressure (“
PEEP”
) in fluid communication with the patient side of the movable partition.

Abstract
A device, system, and method for isolating a ventilator from one or more patients in which the delivery conditions of gas delivered to an isolation device from a ventilator may drive the delivery of breathing-gas delivered to one or more patients, the breathing-gas having the same or different delivery conditions. In one embodiment, an isolation device may have a housing and a movable partition. The movable partition may be joined to the housing, The movable partition may have a patient side on a first side of the partition and an actuating side on a second side of the partition. The isolation device may include an inlet pressure regulator on the actuating side and/or an exhaust pressure regulator on the patient side. These regulators may alter the delivery conditions (including, but not limited to, pressure and volume) of breathing-gas delivered to a patient.

36. A method for sharing a single ventilator between at least two patients comprising the steps of:
-
providing a ventilator; providing a first isolation device having an inlet connected to the ventilator; providing a second isolation device having an inlet connected to the ventilator; utilizing the ventilator to drive a respiratory cycle in each of the first and second isolation devices; and utilizing the first isolation device to provide mechanical ventilation of the lungs of a first patient and the second isolation device to provide mechanical ventilation of the lungs of a second patient. - View Dependent Claims (37, 38, 39)

40. A method for enhancing the performance of a ventilator comprising the steps of:
-
providing a ventilator; providing an isolation device having a movable partition for separating gas in an actuating side of the isolation device, from gas in a patient side of the isolation device, wherein the isolation device has an inlet on the actuating side connected to the ventilator, wherein the isolation device has an inlet pressure regulator on the actuating side, and wherein the isolation device has an exhaust pressure regulator on the patient side; utilizing the ventilator to drive a respiratory cycle in the isolation device; and utilizing the isolation device to provide mechanical ventilation of the lungs of a patient.
