Membranes in medical process engineering . Synthetic membranes not only represent the essential components of an artificial kidney or an artificial lung but are also used as wound dressing and in systems for controlled release of drugs in certain long-term therapeutic measures or as part of an artificial pancreas. By far the greatest present economic significance of membranes is their use in the so-called artificial kidney. Considerable cost saving would result if patients could undertake ?home dialysis”?. This requires the development of new, simpler artificial kidneys and thus higher-performance membranes. The latest trend in ?artificial kidneys”?, the so-called method of ?hemodiafiltration”? warants special mention. The separation process is no longer effected only by diffusion but also by convection, i.e. the driving force is the pressure difference between the two sides of the membrane. This paper addresses problems encountered in the development and use of membranes in medicine, recent applications such as the controlled release of active components, or plasma separation, and demonstrates the potential of membranes in medicine. 相似文献

传统的金属材料和陶瓷材料由于刚性过强而缺乏适当的挠性和弹性,对于人体组织某些部位的代用和修补出现不同程度的副作用。鉴于此,兼具刚性与柔性、良好的生物相容性和血液适应性等特点的聚氨酯材料引起了众多研究者的关注。一系列医用聚氨酯材料被研发并广泛应用,在医药领域占据着重要地位。本文首先简要介绍了医用聚氨酯的发展背景,总结了其主要的组成结构和性能特点。主要综述了聚氨酯在人造心脏及辅器、人造血管及支架、人造皮肤、伤口敷料和记忆矫形等领域的研究进展。然后重点概述了目前医用可降解聚氨酯材料的研究现状,并对医用聚氨酯材料现存问题进行了探讨,指出聚氨酯在该领域进一步发展的关键技术是实现准确把控聚氨酯材料在生物体内的降解性。 相似文献
