ABSTRACT:
An aspirating device includes a flexible catheter having a proximal first end, a distal second portion including a second end and a passageway therethrough. The catheter is adapted for insertion into the trachea of a patient and includes at least one aperture in the second portion for allowing fluid communication between the exterior of the catheter and the passageway. A housing includes a proximal end having a proximal opening, a distal end having a distal opening and a side wall therebetween defining a conduit in the housing. The catheter is positioned in the proximal opening and capable of passing through the distal opening. A catheter connector fitting on the housing is provided for connecting the first end of the catheter to the housing. A vacuum connector fitting is provided for facilitating fluid communication between the catheter connector and the source of vacuum so that when vacuum forces are applied through the vacuum connector fitting the vacuum forces are communicated to the passageway of the catheter. A flexible envelope is connected to the housing so that substantially all portions of the catheter between the catheter connector fitting and the proximal opening are within the envelope. The envelope is flexible enough to allow manual movement of the catheter through the distal opening by grasping the envelope adjacent to a portion of the catheter and manually moving the catheter.
