Abstract

An apparatus, method and system for non-invasive breathing assistance to a patient. The apparatus comprises a hose or other gas conduit with a valve. Proximity of the patient to a sensor causes the valve to open, directing a pressurized stream of air or other gas at the patient'"'"'s mouth, assisting the patient in breathing.

Claims

1. A device for directing a pressurized stream of gas from a gas source toward a patient having a mouth, the device comprising:

a. an inlet to receive gas from the source;

b. an outlet for directing the stream toward a vicinity of the patient'"'"'s mouth;

c. a conduit for delivering the stream from the inlet to the outlet;

d. a sensor for detecting a respiratory need of the patient, the sensor generating a signal based on the respiratory need;

e. a valve inserted in the conduit for controlling the stream; and

f. a controller for controlling the valve, the controller connected to the sensor, the controller actuated based on the signal,

wherein the device is capable of operation with the device not contacting the patient.

2. A device according to claim 1, wherein the sensor detects the respiratory need through proximity of the patient to the sensor.

3. A device according to claim 1, wherein the sensor is a switch.

4. A device for directing a pressurized stream of gas from a gas source toward a patient having a mouth, the device comprising:

a. an inlet to receive gas from the source;

b. an outlet for directing the stream toward a vicinity of the patient'"'"'s mouth;

c. a conduit for delivering the stream from the inlet to the outlet;

d. a by-pass vent inserted in the conduit;

e. a sensor for detecting a respiratory need of the patient, the sensor generating a signal based on the respiratory need;

f. a valve inserted in the conduit for dividing the stream between the outlet and the vent; and

g. a controller for controlling the valve, the controller connected to the sensor, the controller actuated based on the signal,

wherein the device is capable of operation with the device not contacting the patient.

5. A device according to claim 4, wherein the sensor detects the respiratory need through proximity of the patient to the sensor.

6. A device according to claim 4, wherein the sensor is a switch.

7. A system for directing a pressurized stream of a gas toward a patient having a mouth to assist in breathing, the system comprising:

a. a source of the stream;

b. an inlet to receive the gas from the source;

c. an outlet for directing the stream toward a vicinity of the patient'"'"'s mouth;

d. a conduit for conveying the stream from the inlet to the outlet;

e. a sensor for detecting a respiratory need of the patient, the sensor generating a signal based on the respiratory need;

f. a valve inserted in the conduit for controlling the stream; and

g. a controller for controlling the valve, the controller connected to the sensor, the controller actuated based on the signal,

wherein the device is capable of operation with the device not contacting the patient.
