Abstract

A ventilation system and method with a ventilating tube, a stylet removably disposed within the ventilating tube, and a proximal housing. A proximal housing includes a proximal end that connects to the ventilating tube, a distal end that connects to a ventilating machine, a lumen between the proximal end and distal end, an external wall between the proximal end and distal end, a filter contained within the external wall, surrounding the lumen, and connecting the proximal end and distal end, and a cavity between the filter and the external wall. A proximal housing contains at least one detection element and can be sensitive to carbon dioxide. The same proximal housing contains at least one treatment element to heat, cool, humidify, dehumidify, or provide medication to the lumen of the proximal housing.

Claims

1. A ventilation system comprising:

a ventilating tube;

a stylet removably disposed within the ventilating tube; and

a proximal housing including;

a proximal end that connects to the ventilating tube;

a distal end that connects to a ventilating machine;

a lumen between the proximal end and distal end;

an external wall between the proximal end and distal end;

a filter contained within the external wall, surrounding the lumen, and connecting the proximal end and distal end; and

a cavity between the filter and the external wall;

said cavity containing at least one detection element or treatment element.

2. The system of claim 1 where the proximal housing is translucent to provide visualization to the cavity.

3. The system of claim 1 where the proximal housing has viewing ports to provide visualization to the cavity.

4. The proximal housing of claim 1 further comprising said at least one detection element positioned within the cavity.

5. The system of claim 4 where the detection element is sensitive to carbon dioxide.

6. The proximal housing of claim 1 further comprising said at least one treatment element positioned within the cavity.

7. The system of claim 6 where the treatment element raises the temperature of the lumen of the proximal housing.

8. The system of claim 6 where the treatment element lowers the temperature of the lumen of the proximal housing.

9. The system of claim 5 where the treatment element humidifies the lumen of the proximal housing.

10. The system of claim 1 where the treatment element dehumidifies the lumen of the proximal housing.

11. The system of claim 1 where the said at least one treatment element delivers a medication to the lumen of the proximal housing.

12. A ventilation method comprising:

providing a ventilating tube;

providing a stylet removably disposed within the ventilating tube; and

providing a proximal housing, wherein providing the proximal housing comprises;

connecting a proximal end to the ventilating tube;

connecting a distal end to a ventilating machine;

providing a lumen between the proximal end and distal end;

providing an external wall between the proximal end and distal end;

providing a filter within the external wall, surrounding the lumen, and connecting the proximal end and distal end; and

providing a cavity between the filter and the external wall;

said cavity containing at least one detection element or treatment element.

13. The method of claim 12 where the proximal housing is translucent to provide visualization to the cavity.

14. The method of claim 12 where the proximal housing has viewing ports to provide visualization to the cavity.

15. The method of claim 12 where the proximal housing further comprises said at least one detection element positioned within the cavity.

16. The method of claim 15 where the detection element is sensitive to carbon dioxide.

17. The method of claim 15 further comprising said at least one treatment element positioned within the cavity.

18. The method of claim 17 where the treatment element raises the temperature of the lumen of the proximal housing.

19. The method of claim 17 where the treatment element lowers the temperature of the lumen of the proximal housing.

20. The method of claim 17 where the treatment element humidifies the lumen of the proximal housing.

21. The method of claim 17 where the treatment element dehumidifies the lumen of the proximal housing.

22. The method of claim 17 where the treatment element delivers a medication to the lumen of the proximal housing.
