Abstract

Embodiments relate to systems and methods for delivery of oxygen or other treatment gases to a patient without requiring physical contact or enclosure of the patient. Embodiments can include a delivery hood, sensing components, and a gas distribution system including one or more gas delivery ports. Gas delivery ports may be individually controlled based on input from the sensing components to alter the volume and orientation of treatment gas flow directed at a patient. Sensing components can include cameras or other sensors that detect the position of a patient'"'"'s head, and gas delivery ports may then be controlled to direct treatment gas flow in the direction of the patient'"'"'s head. Embodiments and methods described thereby allow for efficient oxygen or other gas delivery to a patient without requiring contact or enclosure of the patient.

Claims

1. A respiratory treatment system comprising:

a gas distribution system; and

at least one sensor, the at least one sensor capable of detecting at least the position of a patient'"'"'s head,

wherein said gas distribution system is controlled in part or in whole by direct or indirect response to input from said at least one sensor.

2. The respiratory treatment system of claim 1, wherein said at least one sensor comprises a camera.

3. The respiratory treatment system of claim 1, further comprising an oxygen sensor, wherein said gas distribution system is further controlled by said oxygen sensor.

4. The respiratory treatment system of claim 1, further comprising a blood oximeter, wherein said gas distribution system is further controlled by said blood oximeter.

5. The respiratory treatment system of claim 1, further comprising a hood capable of at least partially confining gases around said patient.

6. The respiratory treatment system of claim 5, wherein said gas distribution system comprises at least one gas delivery port, the at least one gas delivery port mounted to said hood.

8. The respiratory treatment system of claim 1, further comprising:

a mechanism for creating at least one stream of gas,

a mechanism for altering the direction of said at least one stream of gas,

wherein said at least one sensor detects at least the location of said patient'"'"'s head, and wherein the orientation of said gas flow contiguous to a patient is modified by altering the direction of the at least one stream of gas towards said patient'"'"'s head.

9. The respiratory treatment system of claim 1,

wherein said gas distribution system comprises at least two groups including a first and a second group of gas delivery ports with each group comprising at least one gas delivery port, wherein the orientation of said gas flow contiguous to the patient is modifiable by altering the volume of gas which flows through the first group of gas delivery ports relative to the volume of gas which flows though the second group of gas delivery ports.

25. The respiratory treatment system of claim 5, wherein at least one sensor is mounted to the hood.

26. The respiratory treatment system of claim 1, further comprising at least one carbon dioxide sensor, wherein the gas distribution system is further controlled by the at least one carbon dioxide sensor.

27. The respiratory treatment system of claim 1, wherein the gas distribution system comprises at least one gas delivery port, the at least one gas delivery port being moveable to point in multiple directions.

12. (canceled)

13. (canceled)

14. (canceled)

15. A respiratory treatment system comprising:

a gas distribution system; and

an extendable hood with at least one open plane which can be adjusted between a retracted and extended position, wherein said gas distribution system distributes gas into the at least partially enclosed space formed by said extendable hood.

16. The respiratory treatment system of claim 15, wherein said gas distribution system comprises at least one gas delivery port, wherein at least one gas delivery port is mounted on said extendable hood.

17. The respiratory treatment system of claim 15, wherein said extendable hood comprises:

a base member comprising a first end and a second end;

a top member comprising a first end and a second end wherein said first end of said top member is hingeably connected to said first end of said base member, and said second end of said top member is hingeably connected to said second end of said base member; and

a flexible covering member comprising a first edge and a second edge, wherein said first edge is operatively connected to said base member, said second edge is operatively connected to said top member, and a position of said base member relative to a position of said top member forms a partially enclosed space under the flexible covering wherein the position of said top member is altered by movement about the hingeable connections with said base member.

20. The respiratory treatment system of claim 17, further comprising a sensor capable of determining the position of the head of a patient, wherein said gas distribution system is controlled based on direct or indirect input from said sensor.

28. The respiratory treatment system of claim 15, further comprising at least one carbon dioxide sensor, wherein the gas distribution system is further controlled by the at least one carbon dioxide sensor.

18. (canceled)

19. (canceled)

21. A method of respiratory treatment comprising:

providing at least one sensor;

using the at least one sensor to determine the position of a patient'"'"'s head;

and providing a gas distribution system wherein a flow of oxygen or other treatment gas is directed in the direction of said patient'"'"'s head based, at least in part, on input from the at least one sensor.

22. The method of claim 21, wherein determining the position of the patient'"'"'s head comprises detecting the position of the patient'"'"'s face.

23. The method of claim 21, wherein determining the position of the patient'"'"'s head comprises detecting the position of the patient'"'"'s face using a camera.

24. The method of claim 21, wherein directing the flow of oxygen or other treatment gas towards a patient'"'"'s head comprises selectively altering the flow of gas in each of a plurality of gas distribution ports.
