Patents by Inventor Fumiko Saitou

Fumiko Saitou has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Autonomic nervous activity monitor, blood processing apparatus, blood collecting apparatus and autonomic nervous activity monitoring method
    Publication number: 20080281247
    Abstract: An autonomic nervous activity monitor capable of predicting occurrence of abnormal reaction depending on autonomic nervous activity and used for medical practice and the like is provided. A blood component collecting apparatus 100 carries out frequency analysis to a pattern of heartbeat which is acquired by an ECG 300 from a donor, and calculates a high frequency component value [msec2] defined as an indicator for parasympathetic activity and a ratio value of a low frequency component to the high frequency component defined as an indicator for sympathetic activity to detect a change in these values on a time-series base. When a judgment circuit 204 predicts that abnormal reaction may occur to a donor after blood collection operation is started, a controller 200 controls a pump 9 to decrease a blood drawing or blood returning speed, or, to stop blood drawing or blood returning operation.
