Title: **Innovations of Toshio Ohtani: A Pioneer in Blood Pressure Measurement**

Introduction

Toshio Ohtani, an accomplished inventor based in Kyoto, Japan, has made significant contributions to the field of medical technology, specifically in blood pressure measurement devices. With three patents to his name, Ohtani's work emphasizes precision and user-friendliness in the measurement of blood pressure.

Latest Patents

Ohtani's latest inventions include a groundbreaking blood pressure meter cuff and a wrist type blood pressure meter cuff. The blood pressure meter cuff is designed to reduce the influence of edge effects by pressurizing only a targeted portion of a blood vessel, allowing for more accurate readings. It features a fluid bag that can be fixed to a limb, and its width is optimized to selectively pressurize a specific section of the radial artery near the body surface. This innovation has been precisely calibrated to ensure the width of the fluid bag is between 15 mm and 25 mm for optimal performance.

Additionally, Ohtani developed a wrist type blood pressure meter cuff aimed at preventing interference from non-selected arteries during measurement. This cuff inflates to apply pressure solely to either the radial or ulnar artery while forming a gap to alleviate pressure on the non-selected artery. This design minimizes the mixing of pulse waves, allowing for a more accurate assessment of blood pressure.
