    • This invention relates generally to a method for fluid transfer and a micro peristaltic pump based upon the method. The micro peristaltic pump, which comprises: a) an actuating part compring a motor and a first force effector driven by the motor; b) a cartridge part comprising an elastic membrane attached to a cartridge body, wherein said elastic membrane attached to said cartridge body forms an enclosed space within the cartridge body comprising at least three chambers, and the cartridge also comprising a second force effector which interacts with the first force effector; c) at least three said chambers have inlets and outlets, which are sealingly connected in tandem. Compared with prior art in the micro pump field, the micro peristaltic pump in this invention can generate much greater actuating forces with equivalent overall size. In addition, since the micro peristaltic pump is composed by two separate parts, with one entirely close and disposable and the other reusable, the performance of this micro pump is very high with low cost for production.
    • 本发明一般涉及一种基于该方法的流体转移方法和微型蠕动泵。 微型蠕动泵,包括:a)一个驱动部件,包括一个马达和一个由马达驱动的第一个力效应器; b)包括附接到盒体的弹性膜的盒部件,其中附接到所述盒体的所述弹性膜在所述盒体内形成包括至少三个室的封闭空间,并且所述盒还包括与第二力效应器相互作用的第二力效应器 第一个力效应器; c)至少三个所述腔室具有串联密封连接的入口和出口。 与微泵领域的现有技术相比,本发明的微蠕动泵可以产生相当大的致动力。 另外,由于微型蠕动泵由两个独立的部件组成,其中一个完全紧密且一次性可重复使用,另一个可重复使用,该微型泵的性能非常高,生产成本低。
