摘要目的探讨一种简单易行的持续恒压快速皮肤扩张技术。方法采用普通输液瓶，一次性输液器，普通弹簧式血压表，医用三通管，血库专用塑料空袋等，装配成一种交互反馈式全封闭型持续恒压皮肤扩张灌注器。扩张过程由患者自行操作，形成交互反馈扩张模式。已用于本科门诊及住院整形美容者14例，共17只扩张器。结果均经1～2次储水囊充液即完成扩张，扩张器容量50～300 ml，扩张时间7～14 d，无1例发生并发症。疗效非常满意。结论交互反馈式全封闭型持续恒压皮肤扩张灌注器是一种新型实用、简单廉价的新皮肤扩张器，本设计基本实现了人们所期望的简单、安全、高效、快捷、舒适的总体目标，值得推广。

abstractsObjective　To search for a simple and rapid skin expansion. Methods　 CCPSEPA-A kind of mutual feedback type continuous normal saline perfusion system was assembled with the use of conventional transfusi on apparatus, sphygmomanometer, three-way stopcocks, plasma bag etc.14 cases ( 17 expanders) were carried out with such a device, controlled by patients themselves. Results 　The volume of expanders was 50～300 ml and the duration of expansion was 7～14 days. All the cases proved a wonderful effect that the expansion was finished by only one or two times of water filling of storage water bag, and without any complications.Conclusion　CCPSEPA is a new skin expansion apparatus of new type and practical ,simple and low price .The general goal of safe,simple, rapid and useful was realized basically by the device,and worth popularizing.
