Abstract

A three-in-one instillation aspiration device configured for (i) instillation of a sampling fluid from a sealed body, (ii) aspiration of the sampling fluid from a target site with collected material into the sealed body, and (iii) transport, without external exposure, of the collected sample to a diagnostic site.

Claims

1. A needleless bronchoalveolar lavage instillation/aspiration device comprising:

a generally cylindrical barrel member and including a lumen;

a distal portion of the barrel member comprising an aperture and a self-sealing member configured for maintaining a fluid-disruptable, resealable barrier to the aperture;

a plunger member disposed slidably in the lumen and providing a generally proximal seal for the lumen; and

a handle member attached to, and configured to axially actuate, the plunger member, where the handle member is removable from the plunger member.

2. The device of claim 1, where the distal portion of the barrel member comprising a self-sealing aperture comprises a removable cap member.

3. The device of claim 2, where the removable cap member is threadedly, sealingly attached to a more proximal portion of the barrel.

4. The device of claim 1, where the distal portion of the barrel member comprising a self-sealing aperture comprises a threaded means for attachment to a catheter.

5. The device of claim 1, where the barrel member further comprises at least one of a clear or translucent portion configured to allow visualization of contents of the barrel.

6. The device of claim 1, where the barrel member further comprises volumetric graduation markings indicating at least a minimum predetermined volume.

7. The device of claim 1, where a proximal end of the self-sealing member is in a position selected from one of flush disposed with and recessed relative to a distal internal surface of the barrel member.

8. The device of claim 1, where a proximal end of the self-sealing member is disposed along a central longitudinal axis of the barrel member.

9. The device of claim 1, where a distal internal surface of the barrel member is generally configured in shape as a truncated cone.

10. The device of claim 9, where a smaller end of the generally truncated-conical distal internal surface is distal relative to a larger end of the generally truncated-conical distal internal surface.

11. The device of claim 9, where a proximal end of the self-sealing member is disposed flush with a smaller end of the generally truncated-conical distal internal surface.

12. The device of claim 1, where the self-sealing member comprises a separate member that is removable from the barrel member.

13. The device of claim 12, further comprising a generally cylindrical wall portion of the barrel member that extends distally beyond the distal portion of the barrel member comprising the aperture and the self-sealing member.

14. The device of claim 13, where the generally cylindrical wall portion comprises a cut-out portion configured to provide tactile access to the self-sealing member.

15. The device of claim 13, where the generally cylindrical wall portion is removable from a more proximal portion of the barrel member.

16. The device of claim 1, where the distal portion of the barrel member comprising the aperture and self-sealing member is removable from a proximal portion of the barrel member.

17. The device of claim 1, where a proximal end portion of the barrel member comprises means for attaching a cap member upon removal of the handle member.

18. A needleless bronchoalveolar lavage instillation/aspiration device comprising:

a generally cylindrical barrel member and including a lumen;

a distal portion of the barrel member comprising a first aperture and a first self-sealing member configured for maintaining a fluid-disruptable, resealable barrier to the aperture;

a proximal portion of the barrel member comprising a second aperture and a second self-sealing member configured for maintaining a fluid-disruptable, resealable barrier to the second aperture; and

a syringe member removably attached to the second self-sealing member.

19. The device of claim 18, where at least one of the distal portion of the barrel member and the proximal portion of the barrel member is removable.

20. The device of claim 18, where a proximal end of the first self-sealing member is flush disposed with a distal internal surface of the barrel member.

21. The device of claim 18, where a proximal end of the first self-sealing member is disposed along a central longitudinal axis of the barrel member.

22. The device of claim 18, where a distal internal surface of the barrel member is generally configured in shape as a truncated cone.

23. The device of claim 22, where a smaller end of the generally truncated-conical distal internal surface is distal relative to a larger end of the generally truncated-conical distal internal surface.

24. The device of claim 22, where a proximal end of the first self-sealing member is disposed flush with a smaller end of the generally truncated-conical distal internal surface.

25. The device of claim 18, where the self-sealing member comprises a separate member that is removable from the barrel member.

26. The device of claim 25, further comprising a generally cylindrical wall portion of the barrel member that extends distally beyond the distal portion of the barrel member comprising the first aperture and the first self-sealing member.

27. The device of claim 26, where the generally cylindrical wall portion comprises a cut-out portion configured to provide tactile access to the first self-sealing member.

28. A needleless bronchoalveolar lavage instillation/aspiration device comprising:

a generally cylindrical barrel member and including a lumen and a proximal plunger-retention structure;

a distal portion of the barrel member comprising an aperture and a self-sealing member configured for maintaining a fluid-disruptable, resealable barrier to the aperture;

the distal portion of the barrel member further comprising a catheter-connection structure, where a connection is thereby provided for a path of fluid communication between the barrel member lumen, the self-sealing member, and a region distal of the self-sealing member;

a plunger member disposed slidably in the lumen and providing a generally proximal seal for the lumen; and

a handle member removably attached to a proximal side of, and configured to axially actuate, the plunger member, where the handle member is removable from the plunger member.

29. A method of performing a lavage procedure comprising the steps of:

providing the device of claim 28 and a catheter having a catheter lumen disposed through its length, where a distal end portion of the catheter is adjacent a site to be subjected to lavage;

providing a volume of an aqueous solution in the barrel lumen between the plunger member and the self-sealing member;

connecting the catheter-connection structure to a catheter in a manner providing a patent path of fluid communication from the barrel lumen through the self-sealing member into the catheter lumen;

directing the handle and plunger distally to instill at least a predetermined portion of the aqueous solution to the site; and

directing the handle and plunger proximally to create a partial vacuum in the barrel lumen and thereby aspirate at least a fraction of the predetermined portion of aqueous solution back into the barrel lumen.

30. The method of claim 29, further comprising a step of removing the handle member.

31. A three-in-one instillation aspiration device configured for (i) instillation of a sampling fluid from a sealed body, (ii) aspiration of the sampling fluid from a target site with collected material into the sealed body, and (iii) transport, without external exposure, of the collected sample to a diagnostic site.
