滚柱泵(ROLLER PUMP)由于性能优良,结构简单,制造容易,(泵管)消毒方便等优点,在体外循环中获得极广泛的应用。当前无论在人工心肺机或人工肾及各种灌注等的泵头中,几乎全部采用滚柱泵结构。本文从动力学和流体力学方面分析滚柱泵的受力状态,阐明血液在泵管中的流动情况,对合理设计泵头,减少血球破坏,增进体外循环手术效果,都将有较大的帮助。 Roller pump (ROLLER PUMP) due to excellent performance, simple structure, easy manufacture, (pump tube) to facilitate the disinfection, etc., in cardiopulmonary bypass obtained a very wide range of applications. At present, both in the heart-lung machine or artificial kidney and a variety of perfusion pump head, almost all use roller pump structure. This paper analyzes the stress state of the roller pump from the aspects of dynamics and fluid mechanics to clarify the flow of blood in the pump tube. It will be of great help in the rational design of the pump head, the reduction of the blood cell damage and the enhancement of the operation effect of the cardiopulmonary bypass .
