Claim Text:
1. A curvature-adjustable endotracheal tube comprising: a hollow cylindrical tube body configured to be inserted into a patient's airway, wherein the tube body comprises: a proximal portion at one end thereof; and a distal portion at the other end thereof; a first corrugated tube disposed on an outer surface of the distal portion so as to allow the distal portion to be bent by bending of the first corrugated tube; a second corrugated tube disposed on an outer surface of the proximal portion so as to allow the proximal portion to be bent by bending of the second corrugated tube; and a curvature-adjusting wire configured to allow an operator to freely adjust a curvature of the tube body to correspond to a curvature of the patient's airway into which the tube body is inserted, wherein the curvature adjusting wire comprises: a first joint fixed to a first side of an inner circumferential surface of the distal portion; a second joint fixed to a second side of an inner circumferential surface of the proximal end; and a connecting portion between the first joint and the second joint, the second side being diametrically opposite to the first side so that the connection portion is disposed slantly within a hollow portion of the tube body, wherein, when the proximal portion is bent by the operator, the distal portion is pulled and bent.
