Abstract

A closed automated suction device (CASD) is described. The device is designed to overcome the need for manual suction and to facilitate strict asepsis in patients who are endotracheally intubated or tracheostomied. The device includes an outer tube with an inner tube concentrically nested within to define a cavity therebetween. The inner tube comprises a passage extended therethrough for providing ventilation, and the cavity between the inner and outer tubes is configured for communication with a vacuum source to provide aspiration.

Claims

1. An endotracheal device, comprising:

an outer tube and an inner tube, the inner tube concentrically nested within the outer tube to define a cavity therebetween, the outer and inner tubes collectively having corresponding first and second ends, the inner tube having a passage extended therethrough, and the outer tube configured for communication with a vacuum source, whereby suction is generated within the cavity.

2. The endotracheal device of claim 1, wherein the inner tube is configured to engage a ventilator at the first end for supplying air.

3. The endotracheal device of claim 1, wherein the second end is configured for intubation.

4. The endotracheal device of claim 1, wherein the cavity between the inner and outer tubes is closed proximate the first end.

5. The endotracheal device of claim 4, further comprising a side tube projecting from the outer tube proximal to the first end, the side tube comprising an inner cavity therein continuous with the cavity between the inner and outer tubes.

6. The endotracheal device of claim 5, wherein the outer tube is configured for communication with the vacuum source via the side tube.

7. The endotracheal device of claim 6, further comprising a collector configured inline with the side tube and the vacuum source for trapping respiratory secretions.

8. The endotracheal device of claim 1, further comprising an inflatable cuff surrounding the outer tube for providing a seal between the device and the tracheobronchial tree.

9. An endotracheal device for providing controlled ventilation and aspiration, comprising:

an outer tube and an inner tube, the inner tube concentrically nested within the outer tube to define a cavity therebetween, the outer and inner tubes collectively having corresponding first and second ends, wherein the cavity between the inner and outer tubes is closed proximate the first end, the inner tube having a passage extended therethrough, and

the outer tube configured for communication with a vacuum source via a side tube projecting from the outer tube proximal to the first end, the side tube comprising an inner cavity therein continuous with the cavity between the inner and outer tubes, whereby suction is generated within the cavity.

10. The endotracheal device of claim 9, wherein the inner tube is configured to engage a ventilator at the first end for supplying air.

11. The endotracheal device of claim 9, wherein the second end is configured for intubation.

12. The endotracheal device of claim 9, further comprising a collector configured inline with the side tube and the vacuum source for trapping respiratory secretions.

13. The endotracheal device of claim 9, further comprising an inflatable cuff surrounding the outer tube for providing a seal between the device and the tracheobronchial tree.

14. A method for endotracheal intubation and aspiration in a patient, comprising:

inserting an endotracheal device into the trachea such that an inner tube of the device is concentrically nested within an outer tube of the device to provide a cavity therebetween;

ventilating the patient by allowing air into a passage extending through the inner tube;

aspirating secretions from the trachea by applying vacuum to the cavity between the outer and inner tubes of the device.

15. The method of claim 14, wherein the inserting step is accomplished by nasotracheal insertion.

16. The method of claim 14, wherein the inserting step is accomplished by orotracheal insertion.

17. The method of claim 14, wherein the inserting step is accomplished by tracheostomal insertion.

18. The method of claim 14, wherein vacuum to the cavity is applied via a side tube projecting from the outer tube.
