The biomedical materials that have been used in the structure of heart pumps are classified as biocompatible, and these can be metals, polymers, ceramics, and composites. Their positions in the pump vary according to the part’s function. Whereas various materials have different properties, all biomaterials chosen for cardiovascular applications should have excellent blood biocompatibility to reduce the likelihood of hemolysis and thrombosis. There are two major categories of the heart pumps; pulsatile and rotary blood pumps (axial and centrifugal) and the features of some of these materials allow them to be used in both. Rotary and pulsatile blood pump devices have to be fabricated from materials that do not result in adverse biological responses. The purpose of this review is to study the available biocompatible materials for the pulsatile and rotary blood pumps as clinically-approved materials and prototype heart pump materials. The current state of bio-compatible materials of rotary and pulsatile blood pump construction is presented. Some recent applications of surface amendment technology on the materials for heart assist devices were also reviewed for better understanding. The limitations of heart assist devices, and the future direction of artificial heart elements have been considered. This review will be considered as a comprehensive reference to rapidly understanding the necessary research in the field of biocompatible materials of pulsatile and blood rotary pumps.

搏动式和旋转式血泵的生物相容性材料:简要回顾

已在心脏泵结构中使用的生物医学材料被归类为生物相容性材料,这些材料可以是金属,聚合物,陶瓷和复合材料。它们在泵中的位置根据零件的功能而变化。尽管各种材料具有不同的特性,但所有选择用于心血管的生物材料都应具有出色的血液生物相容性,以减少溶血和血栓形成的可能性。心脏泵主要分为两大类:搏动式和旋转式血泵(轴向和离心式)以及其中一些材料的特性使它们可以同时使用。旋转式和脉动式血泵装置必须由不会导致不良生物学反应的材料制成。这篇综述的目的是研究可用于脉动和旋转血泵的生物相容性材料,作为临床认可的材料和原型心脏泵材料。介绍了旋转和脉动血泵结构的生物相容性材料的现状。为了更好的理解,还对表面修饰技术在心脏辅助设备材料上的一些最新应用进行了综述。已经考虑了心脏辅助装置的局限性以及人造心脏元件的未来发展方向。这篇综述被认为是快速理解脉动和血液旋转泵生物相容性材料领域必要研究的全面参考。介绍了旋转和脉动血泵结构的生物相容性材料的现状。为了更好地理解,还对表面修饰技术在心脏辅助设备材料上的一些最新应用进行了综述。已经考虑了心脏辅助装置的局限性以及人造心脏元件的未来发展方向。这篇综述被认为是快速理解脉动和血液旋转泵生物相容性材料领域必要研究的全面参考。介绍了旋转和脉动血泵结构的生物相容性材料的现状。为了更好的理解,还对表面修饰技术在心脏辅助设备材料上的一些最新应用进行了综述。已经考虑了心脏辅助装置的局限性以及人造心脏元件的未来发展方向。这篇综述被认为是快速理解脉动和血液旋转泵生物相容性材料领域必要研究的全面参考。已经考虑了人造心脏元件的未来方向。这篇综述被认为是快速理解脉动和血液旋转泵生物相容性材料领域必要研究的全面参考。已经考虑了人造心脏元件的未来方向。这篇综述被认为是快速理解脉动和血液旋转泵生物相容性材料领域必要研究的全面参考。
