甩尾測痛儀主要是用于測量大、小鼠尾巴部受紅外熱刺激的痛覺閾值。實(shí)驗時，當(dāng)動物感覺疼痛，尾巴會輕敲臺面，內(nèi)置傳感器會立刻檢測到，停止計時和關(guān)閉光源，即儀器自動記錄反應(yīng)時間和光源強(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)驗動物的尾巴上。實(shí)驗時，操作人員將實(shí)驗動物置于儀器上，把動物的尾巴放在紅外光源處，接受刺激。

特征

• 儀器自動記錄實(shí)驗數(shù)據(jù)

• 精度高，避免人為因素引起的誤差

• 包含U盤和軟件
