Abstract
A nasal respiration measurement device includes a base member in which a measurement flow path that is in fluid communication with a nostril of a user is formed to pass through the base member, and a pressure resistance portion that protrudes from an inner wall surface of the measurement flow path.
Claims23
A nasal respiration measurement device, comprising:
- a base member in which a measurement flow path that is in fluid communication with a nostril of a user is formed to pass through the base member;
- and
- a pressure resistance portion that protrudes from an inner wall surface of the measurement flow path.

A nasal respiration measurement device, comprising:
- a base member in which a measurement flow path that is in fluid communication with a nostril of a user is formed to pass through the base member;
- and
- a pressure resistance portion that protrudes from an inner wall surface of the measurement flow path,
- wherein a communication port communicating with a space in which a pressure sensor is disposed is formed in the inner wall surface of the measurement flow path, and
- the pressure resistance portion has an asymmetric shape between an upstream side and a downstream side thereof.
