Title: Katumi Tominaga: Innovator in Liquid Infusion Technology

Introduction

Katumi Tominaga is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of liquid infusion technology, holding a total of 3 patents. His work focuses on improving the efficiency and accuracy of liquid infusion systems.

Latest Patents

Tominaga's latest patents include a liquid infusion apparatus that features a first sensor designed to recognize the mounting position of the sensor as a counting number of instruction pulses to a pulse motor. This sensor is strategically arranged along a plate with slits of an encoder, positioned between the connection point of a pushing holder to a plunger and the start position where the holder separates from the plunger. The apparatus also includes a counting means that resets when the first sensor is detected by a position detecting device, which moves with the pushing holder. This innovation calculates the time required to complete the liquid infusion based on the distance between the plunger connection and the finish position, along with a predetermined infusion speed.

Another patent by Tominaga describes a liquid infusion apparatus that secures the outer cylinder of a syringe and includes a driver for pushing the plunger in a specific direction to expel liquid. This design incorporates an incremental linear encoder along the feeding axis of the driver, with a detector mounted on the slider portion to generate signals indicating the plunger's movement. Additionally, a sensor near the liquid exhaust port generates signals about the plunger's position when a small section of remaining liquid is detected.

Career Highlights

Throughout his career, Tominaga has focused on developing innovative solutions that enhance the functionality of medical devices. His patents reflect a commitment to improving patient care through advanced technology.
