Abstract

The present invention relates to a sputum trap for an aspiration and respiratory support system which includes a manifold attachable to a specimen collection vial that is interposed between, and attached to, a suction control device and suction catheter device. The sputum trap allows for the collection of sputum directly from a patient through a suction catheter without causing a loss of Positive End Expiratory Pressure (PEEP) in the respiratory support system. The manifold includes a manifold body that has a first connector and a second connector for attachment to the suction control device and suction catheter, respectively, and an open port for secure attachment to the specimen collection vial. The manifold body further includes tethered first and second caps adapted for sealing the first and second connectors respectively from fluid flow communication once sufficient sputum has been collected in the specimen collection vial. A nest is formed on the top portion of the manifold body for conveniently storing the first and second caps during the collection of sputum without interfering with the operation of device.

Claims

1. A manifold for attachment to a collection vial comprising:

a manifold body, said manifold body forming a first connector for attachment to a suction catheter, a second connector for attachment to a suction control device and an outlet for attachment to the collection vial, said manifold body including a first cap and a second cap, each of which include open end portions, for sealing said first and second connectors respectively, said manifold body further including a nest defining a cavity configured for receiving at least a portion of said first and second caps to facilitate storing said first and second caps in an open end relationship, wherein said open end of one of said first and second caps is configured for engagement with said open end of the other of said first and second caps for preventing contamination of said first and second end caps.

2. The manifold according to claim 1, wherein said first cap includes a top portion and a bottom portion, said bottom portion being adapted for storage inside said cavity of said nest.

3. The manifold according to claim 2, wherein said second cap includes an interior space, said interior space adapted for receiving said top portion of said first cap.

4. The manifold according to claim 1, wherein said first and second caps are tethered to said manifold body.

5. The manifold according to claim 1, wherein the nest includes at least one guide member having at least a portion thereof disposed within the cavity.

6. The manifold according to claim 1, wherein the nest includes a plurality of guide members being formed along an inner wall of the nest.

7. A manifold for attachment to a collection vial comprising:

a manifold body, said manifold body forming a first connector for attachment to a suction catheter, a second connector for attachment to a suction control device and an outlet for attachment to the collection vial, said manifold body including a first cap and a second cap, each of which include open end portions, for sealing said first and second connectors respectively, said manifold body further including a nest for storing said first and second caps in an open end relationship, wherein said open end of one of said first and second caps is coupled to said open end of the other of said first and second caps for preventing contamination of said first and second end caps, said cavity adapted for storing said first cap, wherein said nest further includes opposed slots.

8. The manifold according to claim 7 wherein said first cap includes opposed securing members, said securing members being adapted for engagement with said opposed slots.

9. A manifold for attachment to a collection vial comprising:

a manifold body, said manifold body forming a first connector for attachment to a suction catheter and a second connector for attachment to a suction control device, said manifold body including a first cap and a second cap for sealing said first and second connectors respectively, said manifold body further including a nest defining a cavity configured for receiving at least a portion of said first and second caps to facilitate storing said first and second caps, wherein said first and second caps are stacked one on top of another in an open end relationship, wherein an open end of one of said first and second caps is configured for engagement with and stacked on top of an open end of the other of said first and second caps for preventing contamination of said first and second end caps.

10. The manifold according to claim 9, wherein said first cap includes a top portion and a bottom portion, said bottom portion being adapted for storage inside said cavity of said nest.

11. The manifold according to claim 10, wherein said second cap includes an interior space, said interior space adapted for receiving said top portion of said first cap.

12. The manifold according to claim 9, wherein said first and second caps are tethered to said manifold body.

13. The manifold according to claim 9, wherein the nest includes at least one guide member having at least a portion thereof disposed within the cavity.

14. The manifold according to claim 9, wherein the nest includes a plurality of guide members being formed along an inner wall of the nest.

15. A manifold for attachment to a collection vial comprising:
