VENTILATORY SUPPORT AND RESUSCITATION DEVICE AND ASSOCIATED METHOD
First Claim
1. An apparatus for providing ventilatory support and resuscitation for a patient, the apparatus comprising:
- a chamber;
at least one port in flow communication with the chamber; and
a flexible diaphragm member positioned within the chamber and configured to seal the port from flow communication with the chamber while seated adjacent to the port and to flex in response to pressure applied thereto so as to allow flow communication between the port and the chamber while the diaphragm is flexing.

Abstract
A ventilatory support and resuscitation device for providing short-term ventilatory support, as well as constant flow, pressure cycled ventilatory support for breathing and non-breathing patients is disclosed. The device includes a chamber and at least one port in flow communication with the chamber. The apparatus also includes a flexible diaphragm member positioned within the chamber and configured to seal the port from flow communication with the chamber while seated adjacent to the port, and to flex in response to pressure applied thereto so as to allow flow communication between the port and the chamber while the diaphragm is flexing. A flow restrictor in flow communication with the chamber may also be included. The device may be coupled to a patient adapter, whereby a manometer, entrainment unit, and safety pop-off and entrainment valve may be coupled thereto.

23. A method for providing ventilatory support and resuscitation for a patient, the method comprising:
-
providing an apparatus comprising; a chamber; at least one port in flow communication with the chamber; and a flexible diaphragm member positioned within the chamber and configured to seal the port from flow communication with the chamber while seated adjacent to the port; and coupling the apparatus to a patient such that the patient and apparatus are in flow communication with one another and such that the diaphragm is configured to flex in response to pressure applied thereto resulting from exhalation by the patient so as to allow flow communication between the port and the chamber while the diaphragm is flexing. - View Dependent Claims (24, 25, 26)

27. A patient adapter configured to be coupled with an apparatus for providing ventilatory support and resuscitation for a patient, the patient adapter comprising:
-
an inlet port configured to couple with a tubing supplying a gas; a patient connection port configured to deliver gas to the patient; and at least one entrainment valve configured to allow additional gas flow to the patient in response to inhalation by the patient but occlude gas from escaping to the environment in response to exhalation by the patient, wherein the at least one entrainment valve comprises a safety pop-off valve configured to open in response to a predetermined pressure and allow gas to escape to the environment. - View Dependent Claims (28, 29)
