Title: Shigekazu Sekii: Innovator in Flow-Velocity Sensors and Catheter Technology

Introduction

Shigekazu Sekii is a notable inventor based in Fuji, Japan. He holds a total of 9 patents that showcase his contributions to the fields of fluid measurement and medical technology. His innovative designs have significantly advanced the capabilities of flow-velocity sensors and multi-luminal catheters.

Latest Patents

One of his latest inventions is a flow-velocity sensor probe. This device includes a thermistor that generates heat when placed in a fluid. The design incorporates a waterproof resin and a metal piece that efficiently radiates the heat generated by the thermistor. The flow velocity of the fluid is measured continuously by monitoring the temperature changes in the thermistor, which is strategically positioned near the metal piece to facilitate heat transfer to the fluid.

Another significant patent is for a method of manufacturing a multi-luminal catheter. This catheter is characterized by the cross-sectional shape of each lumen at the connection point for an extension tube, which is molded to match the outer shape of the extension tube. This innovation allows for a smooth and hermetic connection between the catheter body and the extension tube, overcoming challenges faced in previous designs. The manufacturing process involves pressing a core metal into each lumen of the catheter body and heating it while inserting the connection portion into a molding die. This method enhances airtightness and connection strength by integrating the extension tube with the catheter.
