果蝇作为经济实用的模式动物，可用于中枢神经系统紊乱、炎症性病变、心血管疾病、癌症以及糖尿病等治疗研究，而这些疾病的发生从生理上来说都与生物个体*的代谢功能异常密切相关。

MAVEn™高通量16通道果蝇代谢监测系统是的美国Sable Systems International动物代谢测量公司生产的一款16通道、高分辨率及自动化的果蝇代谢监测仪器，可广泛用于代谢紊乱造成的各种流行疾病治疗的机理研究。

MAVEn™果蝇代谢系统作为果蝇代谢分型监测方面的产品，主要具备以下特点：

1. 改变了传统的单只果蝇的封闭或半封闭式测量模式，实现每个测量室都有实时气流通过的*开放式测量，避免了测量时内出现缺氧（hypoxia）或高碳酸血症（hypercapnia），可一次测量多达16只个体。

2. 15秒就可以完成一只果蝇的代谢监测，这代表了目前技术的水平。

3. 数据可以通过SD卡把带时间标签的CSV格式直接导出到电脑。

4. 可选配FLIC果蝇觅食、AD-2果蝇活动、气体（氧气、二氧化碳、水汽以及其它可检测气体）等监测单元。

5. 参考文献*多，高达4万多篇，属于前沿科技。
