First Claim
Patent Images
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.

Abstract
Provided is a curvature-adjustable endotracheal tube. The curvature-adjustable endotracheal tube includes: a hollow cylindrical tube body configured to maintain a patient'"'"'s airway; and a curvature-adjusting wire configured to allow an operator to freely adjust the curvature of the tube body to correspond to the curvature of the patient'"'"'s airway into which the tube body is inserted. Both ends of the curvature-adjusting wire are respectively fixed to a distal portion and a proximal portion of the tube body such that the distal portion is pulled and bent when the proximal portion is bent by the operator.
