Abstract

The invention relates to an in-vitro hemodynamic characteristic test device. The in-vitro hemodynamic characteristic test device mainly comprises a constant-temperature control box, a peristaltic pump, a pressure sensor, a non-contact microscope velocity-measuring system and the like. The constant-temperature control box is connected through a pipeline and forms a closed circulation loop, simulation blood containing tracer particles is placed in the constant-temperature control box, and an outlet of the constant-temperature control box penetrates through the peristaltic pump through a silica gel hose and is connected with an inlet of the constant-temperature control box through a testing region transparent elastic hose; valves are installed at the connecting positions of the silica gel hose and the testing region transparent elastic hose respectively on the front and rear portion of a testing region, and the testing region transparent elastic hose is connected with the silica gel hose through silica gel connectors; the pressure sensor and the non-contact microscope velocity-measuring system are installed at the test section position of the testing region transparent elastic hose. The test device can provide continuous simulation pulsation blood flow, is provided with a hemodynamic characteristic parameter testing system and is capable of testing hemodynamic characteristic parameters such as blood flow velocity, wall pressure and wall shear stress in different vessels.

Description

Technical field [0001] The invention belongs to the technical field of biomedicine and measurement and control, and relates to an external hemodynamic characteristic testing device. Background technique [0002] The shape and diameter of blood vessels in various parts of the human body are not the same. The diameter of blood vessels may also change in the same individual at different ages. If vascular lesions such as cardiovascular disease, etc., may also lead to changes in blood vessels, the blood flow status of blood vessels will also vary. In the human vascular system, the main hemodynamic parameters are: blood flow velocity, wall shear force, wall pressure and so on. Among them, blood flow velocity, wall shear force and wall pressure respectively represent blood flow, blood flow resistance and blood pressure. [0003] It is difficult to test the vascular hemodynamic characteristic parameters directly in the human body, and the experimental environment and conditions are harsh....
