Document Type and Number:

WIPO Patent Application WO/2014/163110

Kind Code:

A2

Abstract:

The objective of the present invention is to provide a nasal intubation tube that reduces, in comparison with conventional nasal intubation tubes, the sense of discomfort when inserting the same into the nasal cavity. Provided is a nasal intubation tube for insertion into the nasal cavity. The 100% tensile stress of the nasal intubation tube is in the range of 0.10-0.70 MPa. The internal diameter of the nasal intubation tube is in the range of 3.0-9.2 mm. The nasal intubation tube preferably satisfies the following formula: 0.030 ≤ 100% tensile stress (MPa) × thickness (mm) ÷ internal diameter (mm) ≤ 0.067 At least a part of the nasal intubation tube is preferably curved. The radius of curvature of the curved part is in the range of 120-160 mm.
