Latest Patents

One of Sakai's latest patents is a liquid supply method and apparatus. This innovative method allows for the accurate determination of the amount of supply solution when preparing a solution for washing water and similar applications. The method involves supplying a minute amount of chemicals to ultrapure water through a primary fluid circulation tube. The apparatus includes a supply section that delivers the supply liquid and a circulation tube with an internal diameter ranging from 0.01 to 1 mm. The pressures in the supply section and the primary fluid circulation tube must satisfy a specific formula for optimal performance.

Another notable patent is the membrane artificial lung, which performs gas exchange between blood and gas via a membrane. This device flows blood on one side of the membrane while oxygen or an oxygen-containing gas flows on the other side. The membrane is made of a hollow fiber material and features a surface with an ionic complex derived from quaternary aliphatic alkylammonium salts and heparin or its derivatives. This innovative design enhances the efficiency of gas exchange in medical applications.
