23 Jul Piston pressure-regulating high-sensitivity small-tension film-shaped biomaterial mechanic detector
Abstract
The invention discloses a piston pressure-regulating high-sensitivity small-tension film-saped biomaterial mechanic detector which comprises a sample fixing ring (4), a sample loading platform (5), arack stand column (7), a top panel (7a), a bearing panel (7b), a movable clamping plate (8), a tensioning threaded rod (9), a dumbbell type screw nut (12), a stepper motor (19), a pressure sensor (1)and a microcomputer (22), and also comprises a locating rod (6), a transparent pressurizing loading box (3), a displacement sensor (13), a three-way valve (16), a piston pressure regulator (17) and aball screw (18). The detector has simple and reasonable structure, can accurately detect low-tension tissue engineering products such as skin, bones, veins, tendon, muscles and the like, and other soft tissue materials, is flexible and convenient in operation and control, can monitor the changing states visually when the sample is detected, can reflect the loading change flexibly and resist environmental interference, and guarantee the accuracy of detected data. The detector provides an ideal mechanic performance detecting tool for batch production and quality control of the tissue engineeringbiomaterials.
