Abstract

A respiratory gas measurement system is described. In one embodiment, the respiratory gas measurement system includes a chamber and an adhesive pad. The chamber is configured to collect a respiratory gas. The adhesive pad includes a substrate. At least a portion of a first surface of the substrate is covered with adhesive. The adhesive on the first surface of the substrate attaches the adhesive pad to a first surface of the chamber. The adhesive pad enables the chamber to attach to a surface of another nasal cannula.

Claims

1. A respiratory gas measurement system, the respiratory gas measurement system comprising:

a chamber configured to collect a respiratory gas;

an adhesive pad, the adhesive pad comprising a substrate, wherein at least a portion of a first surface of the substrate is covered with adhesive; and

wherein the adhesive on the first surface of the substrate attaches the adhesive pad to a first surface of the chamber.

2. The respiratory gas measurement system of claim 1, wherein at least a portion of a second surface of the substrate is covered with adhesive.

3. The respiratory gas measurement system of claim 2, further comprising:

a nasal cannula, wherein the adhesive on the second surface of the substrate attaches the adhesive pad to a surface of the nasal cannula.

4. The respiratory gas measurement system of claim 1, wherein the adhesive pad comprises a flexible adhesive strip, the flexible adhesive strip including a substrate strip, the substrate strip being an extension of the substrate of the adhesive pad, wherein at least a portion of the substrate strip is covered with adhesive.

5. The respiratory gas measurement system of claim 1, further comprising:

at least one opening on a second surface of the chamber, the opening being configured as an inlet for the respiratory gas.

6. The respiratory gas measurement system of claim 1, further comprising:

a tubular stem extending from a third surface of the chamber, the tubular stem configured as an outlet for the respiratory gas.

7. The respiratory gas measurement system of claim 6, wherein the tubular stem comprises a flexible adhesive stem strip, the flexible adhesive stem strip being configured to adhesively join the tubular stem to a tube of a nasal cannula.

8. The respiratory gas measurement system of claim 6, wherein the tubular stem comprises a connector, the connector being configured to enable measurement of the respiratory gas.

9. The respiratory gas measurement system of claim 6, wherein the tubular stem comprises a semi-circular clip, the semi-circular clip being configured to mechanically join the tubular stem to a tube of a nasal cannula.

10. An attachable nasal cannula, the attachable nasal cannula comprising:

a chamber configured to collect a respiratory gas;

a flexible adhesive strip attached to the chamber, the flexible adhesive strip comprising a substrate strip, wherein at least a portion of the substrate strip is covered with adhesive.

11. The attachable nasal cannula of claim 10, further comprising:

an adhesive pad, the adhesive pad comprising a substrate pad, the substrate pad being an extension of the substrate strip of the flexible adhesive strip, wherein at least a portion of a first surface of the substrate pad is covered with adhesive, and wherein the adhesive on the first surface of the substrate pad attaches the adhesive pad to a first surface of the chamber.

12. The attachable nasal cannula of claim 10, further comprising:

at least one opening on a second surface of the chamber, the opening being configured as an inlet for the respiratory gas.

13. The attachable nasal cannula of claim 10, further comprising:

a tubular stem extending from a third surface of the chamber, the tubular stem configured as an outlet for the respiratory gas.

14. The attachable nasal cannula of claim 13, further comprising:

a flexible adhesive stem strip attached to the tubular stem, the flexible adhesive stem strip being configured to adhesively join the tubular stem to a tube of a second nasal cannula.

15. The attachable nasal cannula of claim 13, further comprising:

a semi-circular clip attached to the tubular stem, the semi-circular clip being configured to mechanically join the tubular stem to a tube of a second nasal cannula.

16. A method for measuring respiratory gas, comprising:

attaching a flexible adhesive strip to a chamber configured to collect a respiratory gas, the flexible adhesive strip comprising a substrate, wherein at least a portion of the substrate is covered with adhesive;

attaching, via the flexible adhesive strip, the chamber to a nasal cannula.

17. The method of claim 16, further comprising:

looping the flexible adhesive strip around the chamber and the nasal cannula to attach the chamber to the nasal cannula.

18. The method of claim 16, wherein the chamber comprises a tubular stem extending from a surface of the chamber, the tubular stem configured as an outlet for the respiratory gas collected in the chamber.

19. The method of claim 18, wherein the tubular stem comprises a flexible adhesive stem strip, the flexible adhesive stem strip comprising a second substrate, wherein at least a portion of the second substrate is covered with adhesive.

20. The method of claim 18, further comprising:

attaching the tubular stem to a tube of the nasal cannula by looping the flexible adhesive stem strip around the tubular stem and the tube of the nasal cannula.
