Title:
DEVICE FOR MEASURING MECHANICAL PROPERTIES OF ELASTIC MATERIAL AND METHOD THEREOF
Document Type and Number:
Japanese Patent JPH05269086
Kind Code:
A
Abstract:
PURPOSE: To measure mechanical properties of fragile wound such as a relatively new wound, fetus wound and the like with an excellent accuracy and repeatability. CONSTITUTION: A subject 14 with a mark on a tissue part having a wound is positioned on a scale 12 and a ring 30 is fixed on the tissue part of a subject 14. Negative pressure gradually increasing with time is applied to the tissue part by a vacuum chamber 16. The pressure of the vacuum chamber 16 is controlled by a vacuum controller 18 and the variation of pressure with time is stored in an processing system 26. Images of the tissue part with time are taken by a video camera 22 and each of the images is digitized by an image digitizer 24. The processing system 26 calculates the mechanical properties by pressure data as a time function from the vacuum controller 18 and aberration data of the wound position obtained from images by digital processing.
