<p>An aspirating device includes a flexible catheter having a proximal portion including a proximal end, a distal portion including a distal end and a passageway therethrough. The catheter is adapted for insertion into the trachea of a patient and includes at least one aperture in its distal portion for allowing fluid communication between the exterior of the catheter and the passageway. A patient housing includes a proximal first end having a first opening, a distal second end having a second opening and a side wall therebetween defining a cavity in the patient housing. The catheter is positioned in the first opening and capable of passing through the second opening. A flexible sleeve surrounds a portion of the catheter having a far end connected at the distal portion of the catheter and a near end connected to the housing so that as the catheter moves distally through the second opening the sleeve covers that portion of the catheter extending outwardly from the second opening between the second opening and the far end of the sleeve. The sleeve is positioned so that when the catheter is moved proximally with respect to the housing the catheter moves through the first opening while leaving the sleeve within the housing.</p> |
