Description

technical field

[0001] The invention relates to the technical field of experimental equipment for testing cell fluid shear stress, in particular to an experimental device for testing cell fluid shear stress. Background technique

[0002] Fluid shear stress is a kind of shear stress generated on the surface of organs, tissues or cells due to the flow of body fluid in the human body. It exists widely in the human body, especially in the skeletal system, cardiovascular system, urinary system, nervous system, etc. Various tissues in the human body play an important role in their normal function. In order to study the physiological function of fluid shear stress in vitro, it is necessary to invent a more complete device that can imitate the fluid shear stress applied to cells.

[0003] Frangos et al. proposed a parallel plate fluid chamber model that applies shear stress to cells, which is gradually recognized by everyone, but the loading device is relatively simple, unable to i...
