Servo-hydraulic system for fatigue and durability testing of medical devices under low force-regime

伺服液压测试系统被要求在5- 15 KN的载荷范围内确定生物医学植入物的动态特性，特别是骨科结构、医疗器械和生物材料。该设备配备齐全，可进行精确和可重复的疲劳寿命研究，以及细胞样品和生物组织的拉伸，弯曲和压缩测试，以及测试生物医学组件（如膝关节，髋关节和脊柱植入物）的耐久性和磨损性能。该设备对三个研究项目至关重要，这些项目的重点是根据ASTM标准开发由晶格材料制成的专利生物医学设备。该设备将补充我们部门目前的试验机，令人惊讶的是，我们部门没有一台能够在低力状态下进行循环疲劳试验的机器。申请人在新成立的生物工程实验室的同事们也需要这种针对生物工程应用的设备。它的收购对于继续进一步开发专利设备以及HQP培训和完成与支持项目相关的研究生项目至关重要。

A servohydraulic test system is requested to determine the dynamic properties of biomedical implants, in particular orthopedic constructs, medical devices and biomaterials, in the load range 5-15KN. The apparatus is fully equipped to perform accurate and repeatable fatigue life studies, and tension, bending, and compression tests of cellular samples and biological tissues, as well to test the durability and wear properties of biomedical components such as knee, hip, and spine implants. The equipment is critical to three research programs pivoting on the development of patented biomedical devices made of lattice materials in accordance to ASTM standards. The apparatus will complement the current testing machines of our department which surprisingly does not own a machine capable of cyclic fatigue testing under low-force regime. The applicant's colleagues of the newly-created Bioengineering lab share the need for such equipment which targets bioengineering applications. Its acquisition is essential to continue the further development of the patented devices as well as for HQP training and completion of graduate student projects related to the supported projects.
