Title: Hajime Kurosawa: Innovator in Respiratory Technology

Introduction

Hajime Kurosawa is a notable inventor based in Sendai, Japan. He has made significant contributions to the field of respiratory technology, holding 2 patents that focus on advanced methods for measuring and assisting respiration. His innovative approaches aim to enhance the precision and effectiveness of respiratory care.

Latest Patents

Kurosawa's latest patents include a respiration impedance measuring device and a respiration impedance display method. These inventions enable continuous measurement of breathing impedance with extremely high precision by executing noise elimination. A loudspeaker applies air vibration pressure through an oscillation wave to the oral cavity, which is generated by a pulse signal that corresponds to the timing of exhalation and inhalation. The pressure inside the oral cavity is detected, and the resulting signal is Fourier-transformed to obtain a spectrum, allowing for the analysis of breathing impedance.

Another significant invention is a system for assisting respiration. This system features a flat, belt-shaped tube made of rubber, equipped with a valve for air introduction. The design includes layers of rubber with varying elasticity, allowing it to intermittently press against the patient's lower breast and upper abdomen. The system incorporates a flow sensor to detect inspiration and expiration, a compressor to supply compressed air, and various valves to regulate pressure during the respiratory cycle.
