Abstract

A dual area pressure pulmonary modulator apparatus which provides constant flow, pressure cycled ventilatory support to patients that is additionally equipped with fluid conduits in the valve mechanism and body that allow the clinician or user to manually actuate inhalation by occluding a fluid path emanating from the modulator. Such feature is useful for when the device stops cycling due to physiological changes of the patient, for determining if the patient is cycling the device or if the device is automatically cycling by nature of its setting, coordinating medical procedures with the breathing of the patient, increasing the PEEP beyond the intrinsic design PEEP of the device for a given PIP setting, increasing inspiratory hold time, and providing an easy to use alternative mode of operation for users with less sophistication.

Claims

1. A device for providing ventilatory support of a patient, comprising:

a. A inlet chamber having an interior end and an exterior end;

b. A valve, said valve including a first actuation area in flow communication with said inlet chamber when said interior end is closed by said valve, said valve including a second actuation area in flow communication with said inlet chamber when said interior end is open, said first actuation area being less than said second actuation area, wherein said valve is configured to open and close by changes in flow pressure applied to said inlet chamber, and wherein the pressure required to open said valve is greater than the pressure required to hold said valve open;

c. A biasing member that provides a restorative biasing force on said valve, wherein said valve is normally biased in a position wherein said inlet chamber is closed, and wherein said pressure applied to said inlet chamber opposes said restorative biasing force;

d. A primary chamber, said primary chamber in flow communication with said inlet chamber when said interior end is open, and wherein said primary chamber is not in flow communication with said inlet chamber when said interior end is closed, and wherein said primary chamber having internal pressure which opposes said restorative biasing force;

e. A secondary chamber, said secondary chamber having an internal pressure which exerts a force on said valve that is in substantially the same direction as said restorative biasing force;

f. A equalization conduit, said equalization conduit providing fluid communication between said primary chamber and said secondary chamber; and

g. An ambient actuation conduit, said ambient actuation conduit providing fluid communication between said secondary chamber and the ambient environment.

2. A device for providing ventilatory support as in claim 1, wherein said biasing member comprises a spring.

3. A device for providing ventilatory support as in claim 1, wherein said valve comprises a piston.

4. A device for providing ventilatory support as in claim 1, wherein said valve comprises a diaphragm.

5. A device for providing ventilatory support as in claim 1, wherein said inlet chamber is in fluid communication with a source of compressed gas.

6. A device for providing ventilatory support as in claim 1, wherein said inlet chamber is in fluid communication with a patient connection port.

7. A device for providing ventilatory support of a patient, comprising:

a. A patient connection port;

b. A source of gas;

c. A valve, said valve opening and closing as a result of pressure at said patient connection port, said valve opening at a pressure greater than pressure required for said valve to close;

d. Said source of gas providing flow to said patient connection port when said valve is closed;

e. A primary chamber, said primary chamber receiving flow from said gas source when said valve is open, resulting force of internal pressure of said primary chamber directed onto said valve in the open direction;

f. A secondary chamber, said secondary chamber having an internal pressure which exerts a force on said valve that is in opposition of internal force of said primary chamber;

g. A equalization conduit, said equalization conduit providing fluid communication between said primary chamber and said secondary chamber; and

h. An ambient actuation conduit, said ambient actuation conduit providing fluid communication between said secondary chamber and the ambient environment.

8. A device for providing ventilatory support as in claim 7, wherein said valve comprises a piston.

9. A device for providing ventilatory support as in claim 7, wherein said valve comprises a diaphragm.

10. A device for providing ventilatory support as in claim 7, wherein said valve is acted upon by a biasing member providing a restorative force.

11. A device for providing ventilatory support of a patient, comprising:

a. A inlet chamber in fluid communication with a patient port and a source of gas;

b. A housing, said housing containing a valve;

c. A primary chamber, said primary chamber contained in said housing and having a greater internal pressure when said valve is open than when said valve is closed;

d. A secondary chamber, said secondary chamber contained in said housing;

e. A ambient actuation conduit, said ambient actuation conduit providing fluid communication between said secondary chamber and the fluid space outside said housing;

f. An exhalation port;

said exhalation port providing fluid communication between said primary chamber and the fluid space outside said housing.

g. Wherein the internal pressure of said secondary chamber is less than the internal pressure of said primary chamber whenever said ambient actuation conduit is un-occluded.

12. A device for providing ventilatory support as in claim 11, wherein said valve comprises a piston.

13. A device for providing ventilatory support as in claim 11, wherein said valve comprises a diaphragm.
