Abstract

A tube for insertion into a trachea having a germicidal light source that is positioned above a cuff that holds the tube in place in the trachea. Activation of the germicidal light source causes an radiation emission that kills undesired bacteria that is fostered by the tube and the cuff, reducing the patient'"'"'s risk of associated disease, and reducing the need for antibiotics.

Claims

1. A tube for insertion into a trachea, said tube comprising

an elongated tube;

an expandable cuff located on a section of said elongated tube that is expanded to hold said tube within a trachea of a user; and

a germicidal light source positioned on said elongated tube and above said expandable cuff, wherein said germicidal light source transmits germicidal light toward said expandable cuff, and

wherein said elongated tube has a conduit formed therein through which an electrical current is passed to said germicidal light source.

2. A tube for insertion into a trachea as described in claim 1, wherein said germicidal light source is a plurality of light emitting diodes.

3. A tube for insertion into a trachea as described in claim 2, wherein said light emitting diodes form an annular ring around said elongated tube.

4. A tube for insertion into a trachea as described in claim 2, wherein said light emitting diodes are secured to said elongated tube by a substantially transparent material.

5. A tube for insertion into a trachea as described in claim 2, wherein said light emitting diodes transmit ultraviolet radiation to an exterior surface of said expandable cuff that is outside of said elongated tube.

6. A tube for insertion into a trachea as described in claim 1, further comprising

a chamber located on said elongated tube and above said expandable cuff, and surrounding at least a portion of said elongated tube, and

wherein a surface of said chamber that is on an exterior portion of said elongated tube is substantially transparent to said germicidal light;

and

wherein said germicidal light source is present within said chamber, and said germicidal light source transmits germicidal light through said surface of said chamber that is substantially transparent to said germicidal light, and toward said expandable cuff.

7. A tube for insertion into a trachea as described in claim 6, wherein said chamber is an annular chamber, and all exterior surfaces of said annular chamber are smooth.

8. A tube for insertion into a trachea as described in claim 1, wherein said germicidal light source transmits ultraviolet radiation.

9. A tube for insertion into a trachea as described in claim 1, wherein said germicidal light source is mounted to said elongated tube.

10. A tube for insertion into a trachea as described in claim 1, further comprising

a chamber that is located on said elongated tube and above said expandable cuff, and wherein a surface of said chamber that is on an exterior portion of said elongated tube is substantially transparent to said germicidal light;

and

wherein said light source is an ultraviolet light source that is present within said chamber, and said light source transmits germicidal light through said surface of said chamber that is substantially transparent to said germicidal light, and toward said expandable cuff.

11. A tube for insertion into a trachea as described in claim 1, wherein said germicidal light source transmits germicidal light to a trachea of a user.

12. A tube for insertion into a trachea as described in claim 1, wherein said germicidal light source transmits germicidal light to a portion of said expandable cuff that is outside of said elongated tube.

13. A tube for insertion into a trachea as described in claim 1, the tube for insertion into the trachea further comprising a timing circuit, wherein when the tube for insertion into the trachea is positioned in the trachea, said germicidal light source intermittently transmits germicidal light.

14. A tube for insertion into a trachea, said tube comprising:

an elongated tube;

an expandable cuff located on a section of said elongated tube that is expanded to hold said tube within a trachea of a user;

a germicidal light source that transmits germicidal light to a trachea of a user;

a chamber that is located on said elongated tube and above said expandable cuff,

wherein a surface of said chamber that is on an exterior portion of said elongated tube is substantially transparent to said germicidal light, and

wherein said germicidal light source is present within said chamber, and said germicidal light source transmits said germicidal light through said surface of said chamber that is substantially transparent to said germicidal light and to an exterior of said chamber.

15. A tube for insertion into a trachea as described in claim 14, wherein said germicidal light source transmits germicidal light to a portion of said expandable cuff that is outside of said elongated tube.
