离体动物心脏灌流技术广泛应用于医学科研的生理、生化、病理、药理等各学科中。分为非作功和作功模型。其中非作功模型简便易行,应用较为广泛。但这一模型是由主动脉逆行灌流心脏,心室不作外功,与生理状态偏离菠大,所能观察的生理指标也较少,不 Isolated animal heart perfusion technology is widely used in medical research in physiology, biochemistry, pathology, pharmacology and other disciplines. Divided into non-work and work model. Among them, non-work model is simple and easy to use and has a wide range of applications. However, this model is a retrograde perfusion of the heart by the aorta, the ventricle is not for external work, and physiological state deviated from spinach, physiological indicators can be observed less, not
