Abstract

A catheter mount is configured to be attached to a respiratory apparatus. The catheter mount includes a plurality of ports in fluid communication with each other. The plurality of ports include an interface port configured to connect to an interface tube, a conduit port configured to connect to a conduit tube, and at least one suction port configured to allow insertion of a suction catheter. The at least one suction port can be positioned to allow the suction catheter, when inserted, access to both the interface port and conduit port.

First claim

What is claimed is:

1. A system comprising a catheter mount configured to be attached to a respiratory apparatus, the catheter mount comprising:
a plurality of ports in fluid communication with each other, wherein the plurality of ports comprise:
an interface port configured to connect to an interface tube;
a conduit port configured to connect to a conduit tube; and
a suction port configured to allow insertion of a suction catheter; and

a valve configured to allow direct access to both the conduit tube and interface tube through the suction port.

2. The system of claim 1 , wherein the valve comprises a flat chamfered surface surrounding an access slit formed in the valve.

3. The system of claim 1 , wherein the valve comprises a flat top surface and/or a flat trailing surface.

4. The system of claim 1 , wherein the valve comprises at least one of a rectangular flat chamfered surface, a substantially semi-circular flat top surface, and a substantially semi-circular flat trailing surface.

5. The system of claim 1 , wherein the valve is deformable.

6. The system of claim 1 , further comprising a breathing circuit comprising an inspiratory tube and an expiratory tube.

7. A system comprising a catheter mount configured to be attached to a respiratory apparatus, the catheter mount comprising:
a plurality of ports in fluid communication with each other, wherein the plurality of ports comprise:
an interface port configured to connect to an interface tube;
a conduit port configured to connect to a conduit tube; and
a suction port configured to allow insertion of a suction catheter; and

a valve associated with the suction port, wherein the interface port comprises an interface axis and the conduit port comprises a conduit axis, wherein the interface axis and the conduit axis intersect the valve.

8. The system of claim 7 , wherein an intersection angle is defined between the conduit axis and interface axis, wherein the intersection angle is between about 60 degrees and about 120 degrees.

9. The system of claim 8 , wherein the intersection angle is about 90 degrees.

10. The system of claim 7 , wherein a first intermediate angle defined as the angle of intersection between the conduit axis and a line perpendicular to a chamfered surface of the valve is approximately equal to 45 degrees.

11. The system of claim 10 , wherein a second intermediate angle defined as the angle of intersection between the interface axis and a line perpendicular to a chamfered surface of the valve is approximately equal to 45 degrees.

12. The system of claim 7 , wherein the suction port comprises a suction port opening, wherein the valve comprises a slit, wherein the opening of the suction port and/or the slit of the valve overlaps with the interface axis and the conduit axis.

13. The system of claim 7 , further comprising a breathing circuit comprising an inspiratory tube and an expiratory tube.

14. A system comprising a catheter mount configured to be attached to a respiratory apparatus, the catheter mount comprising:
a plurality of ports in fluid communication with each other, wherein the plurality of ports comprise:
an interface port configured to connect to an interface tube;
a conduit port configured to connect to a conduit tube; and
a suction port configured to allow insertion of a suction catheter; and

a valve, wherein the interface port comprises an interface axis and the conduit port comprises a conduit axis, wherein the valve is associated with the suction port and is configured to allow the suction catheter to be inserted through the valve and selectively extend along the interface axis or the conduit axis.

15. The system of claim 14 , wherein the valve comprises at least one slit.

16. The system of claim 14 , wherein the valve comprises a slit, the slit being configured to enable the suction catheter to be inserted through the slit to access the interface port and the conduit port, the slit being configured to return to an original shape when the suction catheter is removed from the slit.

17. The system of claim 14 , wherein the valve comprises an annular locking slot, wherein the suction port comprises an engagement lip configured to be received within the annular locking slot of the valve.

18. The system of claim 17 , wherein the suction port comprises an opening, the annular locking slot being sized and shaped slightly larger than the opening.

19. The system of claim 14 , wherein the valve is configured to provide a substantially hermetic seal.

20. The system of claim 14 , further comprising a breathing circuit comprising an inspiratory tube and an expiratory tube.
