Title: Satoshi Egawa: Innovator in Electronic Blood Pressure Measurement

Introduction

Satoshi Egawa is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of medical technology, particularly in the development of electronic blood pressure measuring devices. With a total of 3 patents to his name, Egawa's work has advanced the accuracy and efficiency of blood pressure monitoring.

Latest Patents

One of Egawa's latest patents is an electronic blood pressure measuring device that includes a cuff, a system for pressurizing the cuff, and pressure and pulse wave sensors integrated within the cuff. This innovative monitor extracts the maximum amplitude of the pulse wave and computes the area between the envelope lines of specific data. Maximum area values are calculated on both the higher and lower sides of the cuff pressure, corresponding to the maximum pulse wave amplitude. From these area values, maximum and minimum blood pressure values are derived. Additionally, the device separates the pulse wave signal into components greater and less than a reference value, smoothing and combining these components to determine blood pressure values based on the cuff pressure readings.

Another patent by Egawa describes an electronic blood pressure meter that features a cuff, a pressure system for pressurizing and evacuating the cuff, and a pressure sensor for detecting the cuff's internal pressure. This meter includes a pulse wave parameter extraction circuit that identifies the maximum level difference in the pulse wave component over specific time intervals. It also provides maximum and minimum pulse wave values corresponding to the pulse wave components during these intervals. The device can derive blood pressure readings from maximum and minimum values on both sides of the cuff pressure.
