甩尾測(cè)痛儀主要是用于測(cè)量大、小鼠尾巴部受紅外熱刺激的痛覺閾值。實(shí)驗(yàn)時(shí)，當(dāng)動(dòng)物感覺疼痛，尾巴會(huì)輕敲臺(tái)面，內(nèi)置傳感器會(huì)立刻檢測(cè)到，停止計(jì)時(shí)和關(guān)閉光源，即儀器自動(dòng)記錄反應(yīng)時(shí)間和光源強(qiáng)度。數(shù)據(jù)可通過U盤、USB數(shù)據(jù)線等導(dǎo)出。

甩尾測(cè)痛儀中有一可調(diào)強(qiáng)度的紅外光源，其紅外光主要是通過一拋物面反射鏡聚焦在實(shí)驗(yàn)動(dòng)物的尾巴上。實(shí)驗(yàn)時(shí)，操作人員將實(shí)驗(yàn)動(dòng)物置于儀器上，把動(dòng)物的尾巴放在紅外光源處，接受刺激。

特征

• 儀器自動(dòng)記錄實(shí)驗(yàn)數(shù)據(jù)

• 精度高，避免人為因素引起的誤差

• 包含U盤和軟件
