Abstract

Bronchoscope adapters and methods of using the same are provided. Aspects of the adaptors include a body having a passageway, a mechanical ventilator access port, a bronchoscope access port configured to receive a bronchoscope into the passageway, and an exit port. The bronchoscope access port comprises a reversibly adjustable inner diameter component that provides locking of the bronchoscope at desired position. The adaptors find use in a variety of different applications.

Claims

1. A bronchoscopy/mechanical ventilation adaptor, the adaptor consisting of:

a body ranging in length from 40 to 50 mm and having;

a first end;

a second end;

a passageway extending from the first end to the second end and having a longitudinal axis;

a mechanical ventilator access port positioned between the first end and the second end of the body configured to operatively couple a mechanical ventilator to the passageway;

a one way snap on swivel for the mechanical ventilator access port;

a bronchoscope access port positioned at the first end of the body and comprising an inner surface thread, wherein the bronchoscope access port is configured to receive a bronchoscope into the passageway; and

an exit port positioned at the second end and configured to operatively connect the passageway to an endo tracheal tube;

a reversibly adjustable inner diameter component having an adjustable inner diameter that ranges from 3.5 to 7 mm and that is configured to provide a magnitude of inner diameter change ranging from 1 to 3.5 mm, wherein the reversibly adjustable inner diameter component comprises a compressible tube aligned with the longitudinal axis;

a rotatable cap member consisting of a body having a proximal and distal end, a through channel extending from the proximal end to the distal end and aligned with the longitudinal axis and an outer surface thread at the distal end, wherein the rotatable cap member is engaged with the inner surface thread of the bronchoscope access port and rotates about the longitudinal axis so as to reversibly adjust the inner diameter of the reversibly adjustable inner diameter component; and

an attached removable plug configured to seal the through channel of the rotatable cap member when a bronchoscope is not present in the bronchoscope access port; and

an inner swivel snap on piece coupled to the exit port;

wherein the bronchoscope access port, compressible tube, rotatable cap member through channel and exit port are coaxial with the longitudinal axis of the passageway and the adaptor provides an unobstructed path for the bronchoscope that is coaxial with the longitudinal axis of the passageway.

2. The adaptor according to claim 1, wherein the reversibly adjustable inner diameter component comprises a compressible polymeric material.

3. The adaptor according to claim 2, wherein the polymeric material comprises a silicone or thermoplastic elastomer (TPE).

4. The adaptor according to claim 1, wherein the adaptor is configured to be operatively employed with a mammal.

5. The adaptor according to claim 4, wherein the mammal is a human.

6. The adaptor according to claim 1, wherein the passageway ranges in length from 40 to 50 mm.

7. The adaptor according to claim 1, wherein the mechanical ventilator port has a longitudinal axis that is orthogonal to the longitudinal axis of the passageway.

8. The adaptor according to claim 1, wherein the compressible tube has a height when in an uncompressed state ranging from 5 to 10 mm.

9. The adaptor according to claim 1, wherein a bronchoscope is present in the passageway.

10. A bronchoscopy method, the method comprising:

providing a patient intubated with a tracheal tube operatively coupled to the exit port of an adaptor according to claim 1; and

introducing a bronchoscope into the access port of the adaptor.

11. The method according to claim 10, wherein the method further comprises adjusting the inner diameter of the reversibly adjustable inner diameter component.

12. The method according to claim 10, wherein the method further comprises imaging pulmonary tissue of the patient with the bronchoscope.

13. The method according to claim 10, wherein the method further comprises removing pulmonary tissue from the patient via a working channel of the bronchoscope.

14. The method according to claim 10, wherein the patient is a human.

15. A bronchoscopy/mechanical ventilation adaptor, the adaptor consisting of:

a body ranging in length from 40 to 50 mm and having;

a first end;

a second end;

a passageway extending from the first end to the second end and having a longitudinal axis;

a mechanical ventilator access port positioned between the first end and the second end of the body configured to operatively couple a mechanical ventilator to the passageway;

a one way snap on swivel for the mechanical ventilator access port;

a bronchoscope access port positioned at the first end of the body and comprising a thread, wherein the bronchoscope access port is configured to receive a bronchoscope into the passageway; and

an exit port positioned at the second end and configured to operatively connect the passageway to an endo tracheal tube;

a reversibly adjustable inner diameter component having an adjustable inner diameter that ranges from 3.5 to 7 mm and that is configured to provide a magnitude of inner diameter change ranging from 1 to 3.5 mm, wherein the reversibly adjustable inner diameter component comprises a compressible tube aligned with the longitudinal axis;

a rotatable cap member comprising a through channel aligned with the longitudinal axis and engaged with the thread of the bronchoscope access port,

wherein the rotatable cap member rotates about the longitudinal axis so as to reversibly adjust the inner diameter of the reversibly adjustable inner diameter component; and

an attached removable plug configured to seal the through channel of the rotatable cap member when a bronchoscope is not present in the bronchoscope access port; and

an inner swivel snap on piece coupled to the exit port;

wherein the bronchoscope access port, compressible tube, rotatable cap member through channel and exit port are coaxial with the longitudinal axis of the passageway and further wherein the bronchoscope is present in the passageway and the adaptor provides an unobstructed path for a bronchoscope that is coaxial with the longitudinal axis of the passageway.

16. The adaptor according to claim 15, wherein the reversibly adjustable inner diameter component comprises a compressible polymeric material.

17. The adaptor according to claim 16, wherein the polymeric material comprises a silicone or thermoplastic elastomer (TPE).

18. The adaptor according to claim 15, wherein the passageway ranges in length from 40 to 50 mm.

19. The adaptor according to claim 15, wherein the mechanical ventilator port has a longitudinal axis that is orthogonal to the longitudinal axis of the passageway.
