Abstract
A reliable, contamination-resistant, single-use, disposable, medical, non-ventilating, aspirating device and method. The device releasibly connects to and aligns with an indwelling endotracheal tube to accommodate advancing of an aspirating catheter tube of the device by manual manipulation through a sterile, flexible envelope and selective evacuation of lung secretions through a closed and sterile two-position, normally-closed, manually-operable valve at the proximal end of the device, while simultaneously accommodating voluntarily respiration by the patient.
