  • Device and method for measuring the parameters of fluid flow
    Patent number: 10215601
    Abstract: Sensor device and method for determining the parameters of fluid flow with a sensor, including an oblong element, extending into fluid flow, fixed mechanically to the body of the sensor device with a flexible link in one end, and a mechanically connected vibration sensor and a data acquisition module connected electrically to the vibration sensor and positioned in the body, which is set to determine the frequency response curve of oscillation caused by liquid flow in the cylindrical element, and to derive the speed and type of fluid flow from the measured frequency response curve.
    Type: Grant
    Filed: July 12, 2017
    Date of Patent: February 26, 2019
    Assignee: Tallinn University of Technology
    Inventors: Maarja Kruusmaa, Asko Ristolainen, Alar Kuusik, Jeffrey Andrew Tuhtan
  • Patient specific anatomic kidney phatnom
    Patent number: 10083632
    Abstract: The invention relates to an anatonnical kidney phantom with calyces for drainage training in interventional radiology. The anatonnical kidney phantom simulator comprises a housing filled with the surrounding material and an anatomical kidney phantom placed into surrounding material. The kidney phantom has a number of cavities simulating parts of the kidney for drainage training in interventional radiology for example the cavities are simulating kidney calyces. The cavities are connected by channels and connecting pipe with outer reservoirs filled with the different colors or the x-ray opaque contrast liquids.
