ABSTRACT:
The present invention discloses an improved fenestrated tracheostomy tube which includes a tubular outer cannula which has a distal end for insertion within the trachea and a proximal end which remains outside of the patient. The outer cannula has a generally circular longitudinal radius of curvature and has an upper wall portion with a longitudinal center along its uppermost surface. The tube includes a disposable inner cannula having a distal end and a proximal end which is adapted to fit closely within and to be removably inserted into the outer cannula. The outer cannula has a plurality of slotted fenestrations through the upper wall portion arranged so that each fenestration is slightly spaced from the longitudinal center and forms an acute angle away from the longitudinal center in the direction of the distal end of the outer cannula. With the foregoing fenestration arrangement, the inner cannula is readily inserted into the outer cannula free from interference with the fenestrations.
