Appl. No.:

8/653938

Inventors:

Assignee:

Ballard Medical Products - Draper UT

International Classification:

A62B 902, A62B 906, A61M 1600

US Classification:

12820716

Abstract:

Apparatus and methods are disclosed by which a closed ventilating system accommodates multiple access to the respiratory system of an intubated medical patient. Access to the respiratory system is accomplished via one or more access ports through an attached accessory device in order to ventilate the lungs of the patent with gas or gasses, aspirate secretions from the lungs, oxygenate the lungs, visually inspect selected parts of the respiratory system, sample sputum and gasses, sense parameters such as flow rates, pressure, and temperature, flush the respiratory tract with washing solution, and/or administer medication, gasses, and/or lavage. The embodiments of the present invention may have such accessory devices permanently fixed to the adaptor or may be removable and replaceable. Access control means may be provided whereby one or more access ports are selectively aligned with the adaptor in order to allow passage of an attached accessory device therethrough.
