傳統(tǒng)動物心電圖測量分析采用體表方式雖操作簡單但是存在測量位置影響大、測量精度不高等局限性而心外膜表面電極測量心電圖操作極為復(fù)雜且創(chuàng)傷性大實驗中較少采用。為解決這一難題Scisence 提供微創(chuàng)的多電極電生理導(dǎo)管設(shè)計使研究者能夠?qū)ι镫娫谡麄€心臟的擴(kuò)散過程進(jìn)行更為深入的測量和分析。

電生理導(dǎo)管系統(tǒng)由八電極電生理導(dǎo)管、電極分配盒及第三方生物電放大器及刺激器組成。

工作原理八電極電生理導(dǎo)管上的每對電極均獨立受控于電極分配盒電極分配盒通過 2mm 針式連接線與第三方生物電放大器或刺激器相連通過采集對應(yīng)的電極對引導(dǎo)的電信號數(shù)據(jù)。八電極電生理導(dǎo)管可用于心臟起搏電信號記錄進(jìn)而用于心臟電生理的各方面研究。
