Noninvasive measurement of heartbeat, respiration, snoring and body movements of a subject in bed via a pneumatic method

K. Watanabe;T. Watanabe;H. Watanabe;H. Ando;T. Ishikawa;K. Kobayashi

IEEE Transactions on Biomedical Engineering

We have developed a noninvasive pneumatics-based system by which to measure heartbeat, respiration, snoring, and body movements of a subject in bed. A thin, air-sealed cushion is placed under the bed mattress of the subject and the small movements attributable to human automatic vital functions are measured as changes in pressure using a pressure sensor having an almost flat frequency response fro...Show More

A study on sleep stage estimation via non-invasive air mattress sensor

T. Ishikawa;H. Ando;K. Kobayashi;E. Nishida;K. Watanabe;T. Nakamura

SICE 2003 Annual Conference (IEEE Cat. No.03TH8734)

In this study, a new automatic sleep stage judgment system was proposed using a non-invasive type air mattress sensor enabling the detection of three useful bio-signals: heartbeat rate, respiratory rate and other body movement. We found that fairly good correlations exist between these signals and the sleep stage. Based on this knowledge, we developed a novel sleep estimation method free from any ...Show More

Wireless data transmission system by FM for health monitoring

K. Kobayashi;T. Ishikawa;K. Watanabe;H. Andou;T. Nakamura;Y. Fujii

SICE 2003 Annual Conference (IEEE Cat. No.03TH8734)

Year: 2003 | Conference Paper |

HTML

This paper describes a novel data transmission system for the air-cushion type biomedical measurement system. Conversational data transmission via coaxial cable sometimes intimidates the patients; the electric cable near the bed is not desirable for medical doctors and nurses, either. To solve this problem, we developed an FM transmission system that is battery driven and transmits signals from DC...Show More

This paper describes a development of health monitoring system that uses a non-invasive type microphone based pressure sensor. The system can estimate the sleep stages from the heartbeats and body motion measured by the sensor. The algorithm for sleep stages estimations as implemented to the single chip microcomputer. The validity of the proposed system is confirmed by comparing the conventional s...Show More
