Abstract

A connector including a flange integrally joining input and output conduits together, with the flange including a slot of litmus paper filler of a characteristic to change color when detecting the presence of carbon dioxide deflected into the slot in capturing airflow through the input and output conduits.

Claims

1. An endotracheal tube safety device connector comprising:

a substantially cylindrical input conduit for coupling with a source of oxygen to be provided to a person in need thereof;

a substantially cylindrical output conduit for coupling with an endotracheal tube to intubate such person;

a flange circumscribing said input and output conduits in joining said conduits together;

an opening internal of said flange in communication with airflow through said conduits when joined together;

first means within said opening of a characteristic to provide a visual change therein in response to the presence of carbon dioxide within said conduits;

and second means extending inwardly into said airflow from an input conduit side of said flange for deflecting carbon dioxide expired from such person into said output conduit towards said first means.

2. The safety device connector of claim 1 wherein said first means is of a litmus paper composition.

3. The safety device connector of claim 2 wherein said litmus paper composition exhibits a change in color upon detection of carbon dioxide.

4. The safety device connector of claim 2 wherein said litmus paper composition fits within a slot in said opening.

5. The safety device connector claim 1 wherein said input conduit is of a diameter greater than the diameter of said output conduit.

6. The safety device connector of claim 1 wherein said second means extends perpendicularly to a longitudinal axis of said input conduit.

7. The safety device connector of claim 1 wherein said second means extends at an angle with respect to said flange rearwardly toward said output conduit.

8. The safety device connector of claim 7 wherein said second means extends rearwardly at an angle of 20 with respect to said flange.

9. The safety device connector of claim 6 wherein said longitudinal axis of said input conduit is co-linear with a longitudinal axis of said output conduit.

11. The safety device connector of claim 9 wherein said second means extends perpendicularly to a longitudinal axis of said input conduit.

12. The safety device connector of claim 9 wherein said second means extends at an angle with respect to said flange rearwardly toward said output conduit.

13. The safety device connector of claim 9, in combination with a first tube coupled to said input conduit, and a second tube coupled to said output conduit.

10. A safety device connector comprising:

a substantially cylindrical input conduit;

a substantially cylindrical output conduit;

a flange circumscribing said input and output conduits in joining said conduits together;

a slot internal of said flange in communication with airflow through said conduits when joined together;

first means within said slot of a characteristic to provide a visual change therein in response to a predetermined presence of component particles within said conduits; and

second means extending inwardly from an input conduit side of said flange for deflecting said component particles toward said first means.
