MEDICAL INJECTION DEVICE

摘要

A medical injection device (4) having switchable mechanical properties comprises a hollow tube section (40) having an inner bore (400), wherein the hollow tube section (40) at least partially is made of a material exhibiting switchable mechanical properties such that the material in a first switching state comprises a first stiffness characterized by a first tensile storage modulus (&Egr;'), in a second switching state comprises a second stiffness characterized by a second tensile storage modulus (&Egr;') smaller than the first tensile storage modulus and is switchable from the first switching state to the second switching state by exposing the material to a stimulus.
