Abstract

The invention provides a generating system capable of continuously outputting pulsating flow. The invention relates to the field of biomedical experiments and tests. The system hardware designed by the invention is mainly composed of a pump body and a valve body, a software control system mainly comprises a set of flow control method, and the pump body is mainly composed of a piston, a lead screwand a guide rod. The piston divides the pump body into a left part and a right part which are respectively provided with an upper water inlet and a lower water outlet. Meanwhile, the piston moves leftand right under the combined action of the lead screw and the guide rod; the output end of the system can continuously output different flow waveforms through the left-right movement of the piston incombination with an external electromagnetic valve, so that the requirements of related flow output, especially biological experiment output, are met. On one hand, different flow waveforms can be output, and the output requirements of different flow waveforms are met; and on the other hand, the specific flow waveform can be continuously output for a long time, and a choice is provided for testingthe requirements of long-time fluid.

Description

technical field [0001] The invention relates to the field of biomedical experiments and tests, in particular to a generating system for continuously outputting pulsating flow. Background technique [0002] Under the action of the heart, a large number of pulsating flows appear in the cardiovascular system, and the current diseases of the cardiovascular system are gradually becoming the main cause of premature morbidity and death among Chinese residents. The emergence of such diseases has greatly affected the economic development of the country Therefore, it is particularly important to study cardiovascular diseases and reduce the incidence of related diseases. [0003] As an important method of disease mechanism research, in vitro experiment is of great significance in clinical disease research and understanding. However, so far, there is no pulsating flow generation system that can satisfy the cycle test applied in the experimental field. Therefore, , a device capable of s...
