Abstract

The invention relates to an experimental apparatus for testing shear stress of cell fluid, which relates to the technical field of experimental devices for testing the shear stress of the cell fluid, and particularly relates to the experimental apparatus for testing shear stress of the cell fluid. The experimental apparatus comprises a principal computer (1), a pump controller (2), a peristaltic pump (3), a liquid storage tank (4), a support (5), a water outlet pipe (6), a water return pipe (7) and a fluid chamber (8), and is characterized in that the pump controller (2) is connected with the principal computer (1) and the peristaltic pump (3), the liquid storage tank (4) is installed on the support in a matching manner, a water returning opening is formed in the upper portion of the liquid storage tank (4), a water outlet is formed in the lower portion of the liquid storage tank (4), an inlet is formed in one end of the fluid chamber (8), an outlet is formed in the other end of the fluid cell (8), one end of the water outlet pipe (6) is connected with the water outlet of the liquid storage tank (4), and the other end is connected with the inlet of the fluid cell (8) in the matching manner by virtue of a pump head of the peristaltic pump (3).

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...
