Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] see figure 1 , the present invention includes the upper and lower liquid storage tanks 1, 9 connected by pipelines and forming a closed circulation loop. The tanks 1 and 9 are provided with a fluid working medium 2, and the outlet of the upper liquid storage tank 1 communicates with the laminar flow generator 6 through a silicone hose 4 with a valve 3, and the silicone hose 4 passes through a peristaltic pump 5, The laminar flow generator 6 is connected to the entrance of the experimental section 7, the flowmeter 8 and the lower liquid storage tank 9 through the rubber tube 10. Since the experimental model is a glass curved surface, in order to avoid the scattering effect of the laser on the curved surface during the measurement process, the experimental section 7 is fixed in the plexiglass cavity, which is filled with fluid working medium, the outlet...

Abstract

The invention discloses an in vitro bionic cycle test system for simulating flowing of blood in arterial aneurysm of a human body under different heartbeat frequencies, relating to the field of biomedicine research on arterial aneurysm and being suitable for carrying out cycle simulating testing on the flowing condition of the blood in the arterial aneurysm of the human body under different heartbeat frequencies. The in vitro bionic cycle test system comprises an upper liquid storage box, a peristaltic pump, a laminar flow generator, an experimental section model, a flow meter, a lower liquid storage box, a cycle pump and a valve. The whole in vitro bionic cycle test system is communicated by a silicon rubber hose and a common rubber hose, fluid is controlled by the valve to flow or stop flowing; the silicon rubber hose is connected to the upper liquid storage box and is downwards connected with the laminar flow generator through the peristaltic pump, a pump head of the peristaltic pump is used for carrying out peristaltic extrusion on the silicon rubber hose; and the laminar flow generator is formed by banding a thin tube embedded in the common rubber hose. Fluid flows out of the laminar flow generator, enters the experimental section model through the common rubber hose, flows into the lower liquid storage box through the flow meter, and returns to the upper liquid storage box through the cycle pump, so that the whole cycle flowing process is completed.

Description

technical field [0001] The invention relates to the field of biomedical research, in particular to an in vitro bionic circulatory experiment system suitable for circulatory simulation of blood flow in human aneurysms under different heartbeat frequencies. Background technique [0002] The human blood flow in vitro bionic circulation experiment system uses the principle of flow similarity to simulate the real blood flow, so as to obtain information similar to the real blood flow. The in vitro bionic experimental system is low in cost, strong in operability, and the experimental conclusion is close to the real situation, so it is widely used in the field of modern biomedical research. [0003] At present, there are many in vitro bionic experimental circulatory systems at home and abroad that simulate blood flow in the human body at a given heart rate, and typical studies such as literature [1] Zhang X, Yao Z, Zhang Y, et al.Experimental and computational studies on the flow f...
