心脏电生理导管系统-尊龙凯时网娱乐官网

传统动物心电图测量分析采用体表无创方式，虽操作简单，但是存在测量位置影响大、测量精度不高等局限性，而心外膜表面电极测量心电图操作极为复杂且创伤性大，实验中较少采用。为解决这一难题，scisence 提供微创的多电极电生理导管，独特设计使研究者能够对生物电在整个心脏的扩散过程进行更为深入的测量和分析。

电生理导管系统由八电极电生理导管、电极分配盒及第三方生物电放大器及刺激器组成。

工作原理：八电极电生理导管上的每对电极均受控于电极分配盒，电极分配盒通过 2mm 针式连接线与第三方生物电放大器或刺激器相连，通过生理记录仪采集对应的电极对引导的电信号数据。八电极电生理导管可用于心脏起搏，电信号记录，进而用于心脏电生理的各方面研究。

电生理导管系统特点

1. 微创八电极电生理导管，可监测心内各个部位的心电信号

2. 可同时引导心内 4 个不同部位的心电信号，可观察心电信号的扩散过程

3. 同一根导管可同时用于采集信号和给予刺激

4. 小鼠 1.1f，电极间距 0.5mm；大鼠 1.9f，电极间距 1.0mm；导管电极间距可定制

5. 聚酰胺材料制作，生物相容性好，兼顾灵活性和刚性，光滑而便于插入

6. 电极分配盒控制每对电极，电极之间互不影响

7. 兼容多种第三方生物电放大器、刺激器、数据采集器，如美国 iworx 的 iwire-biox、ix-ra-834 等

8. 动物实验用，不能用于人体
