The prototype of the miniature vibrating flow pump (VFP) is developed for the external shunt catheter. The cross-slider mechanism is applied to vibrate the tube, which causes the pumping effect. This mechanism results in successful development of the miniature and lightweight VFP. By the use of the prototype VFP, the experiment of the basic pump performance is made in detail based on the authorized procedure in the research field of fluids engineering. The typical H-Q curve of VFP, which is the relationship between the pump head and the flow rate, can be obtained. This result suggests that the miniature VFP developed here can be expected to be used as the booster pump for the external shunt catheter in clinical applications.
微型振动流泵（VFP）的原型是为外置分流导管开发的。采用十字滑块机构使导管振动，从而产生泵送效果。该机构成功研制出了微型轻量化的VFP。利用VFP原型，依据流体工程研究领域的权威程序详细开展了基本泵性能实验。可得到VFP典型的H-Q曲线，即泵压头与流量之间的关系。这一结果表明，此处研制的微型VFP有望在临床应用中用作外置分流导管的增压泵。
