Abstract

The invention discloses a device of extracorporally imitating blood pressure fluctuation rising and an application method and an application, and relates to the field of medical research tools. An imitation blood pressure pump and an imitation blood pressure fluctuation pump are respectively arranged, so that imitation blood pressure and blood pressure fluctuation change are suffered from the adjustment of different regulating units. Separating adjusting effects of the imitation blood pressure and blood pressure fluctuation change are achieved. The device of extracorporally imitating blood pressure fluctuation rising solves the problem that no proper extracorporal model for studying the blood pressure fluctuation rising exists.

Description

Technical field [0001] The invention relates to the field of medical research appliances, in particular to a device for simulating the increase of blood pressure fluctuation in vitro, and its use method and application. Background technique [0002] In vivo experimental studies have shown that increased blood pressure volatility is an independent risk factor for target organ damage in hypertension. Studying the mechanism of target organ damage caused by increased blood pressure volatility and finding corresponding intervention methods is one of the important topics in hypertension research. [0003] The mechanism by which increased blood pressure volatility causes organ damage is still unclear. Scholars speculate that abnormal hemodynamics caused by increased blood pressure volatility will directly lead to changes in blood composition and function, which may cause damage to various organ functions. One of the reasons. However, due to the following limitations, this assumption has...
