Title: Innovations by Yoshihisa Urushida

Introduction

Yoshihisa Urushida is a notable inventor based in Tokorozawa, Japan. He has made significant contributions to the field of medical technology, particularly in anesthesia apparatuses. With a total of 4 patents, his work reflects a commitment to enhancing safety and efficiency in medical devices.

Latest Patents

One of Urushida's latest patents is a gas flow control system for an anesthesia apparatus. This innovative system includes an oxygen gas pressure reducing valve that reduces the primary pressure of oxygen gas to a secondary pressure. Additionally, it features an anesthetic gas pressure reducing valve that performs a similar function for anesthetic gas. A pressure control valve is connected to the secondary side of the anesthetic gas pressure reducing valve and is responsive to the secondary pressure of the oxygen gas. This design ensures that when the secondary pressure of the oxygen gas is zero, the pressure control valve closes, effectively cutting off the supply of anesthetic gas. Another significant patent is an improvement in a flow restrictor for use in a flowmeter. This device measures flow rate based on the pressure drop caused by laminar flow, utilizing the principle that the pressure drop is proportional to the flow rate. The flow restrictor consists of a cylindrical member housed within a fluid inlet and outlet, featuring grooves or spiral grooves that facilitate fluid passage.
