Title: Innovations of Cheng-tai Xie in Medical Technology
Introduction
Cheng-tai Xie is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of medical technology, particularly in the development of devices that analyze light-absorbing materials in living tissues. With a total of 3 patents to his name, his work has the potential to enhance diagnostic capabilities in healthcare.
Latest Patents
One of Cheng-tai Xie's latest patents is a "Probe and apparatus for determining concentration of light-absorbing materials in living tissue." This innovative probe includes a light irradiating device and a light receiving device, which are positioned to sandwich living tissue. The light irradiating device features a light source and a scattering plate, while the light receiving device consists of a photo diode and a light scattering portion. This arrangement allows for accurate measurement of the attenuation of living tissue, ensuring that non-absorbing attenuation remains independent of wavelength. Furthermore, the absorbing attenuation is unaffected by the thickness of the living tissue or the depth of the blood layer.
Another notable patent is the "Apparatus for determining the concentration of light-absorbing materials." In this invention, light beams of various wavelengths are emitted from a light generating device and transmitted through living tissue. The transmitted light is converted into electrical signals by a photoelectric transducing device. A pulsation calculating device then analyzes the absorbance pulsation of the tissue for each wavelength, leading to the calculation of the concentration of light-absorbing materials in blood.
