Ugo Basile 甩尾測(cè)痛儀旨在準(zhǔn)確測(cè)量大鼠或小鼠尾部紅外熱刺激的傷害感受閾值。
新:明亮的觸摸屏增強(qiáng)了可用性和直觀的菜單
新:腳踏板驅(qū)動(dòng)的自動(dòng)甩尾檢測(cè)以實(shí)現(xiàn)重復(fù)性和人體靈敏度
Ugo Basile甩尾測(cè)痛儀是全球常用和有效的:超過 3,000 次引用和數(shù)十年的經(jīng)驗(yàn)!
工作原理:
操作員開始刺激:當(dāng)動(dòng)物感到疼痛并甩動(dòng)尾巴時(shí),傳感器會(huì)檢測(cè)到它,停止計(jì)時(shí)器并關(guān)閉燈泡。因此確定并自動(dòng)記錄動(dòng)物的反應(yīng)時(shí)間。
使用方法:
- 甩尾測(cè)痛儀Tail Flick 基本上由一個(gè) IR 源組成,其強(qiáng)度可調(diào)的輻射能量通過實(shí)體拋物面鏡聚焦在動(dòng)物尾巴上。
- 操作員將動(dòng)物放在儀器上,不受阻礙的上面板,其尾巴放置在齊平安裝的窗戶上,接收紅外能量。該儀器可方便地用于刺激鼠尾;需要時(shí),鼠標(biāo)支架可作為可選件提供。
- 操作員通過踏板開關(guān)或觸摸屏啟動(dòng)圖標(biāo)啟動(dòng)刺激和相關(guān)反應(yīng)時(shí)間計(jì)數(shù)器。
- 當(dāng)動(dòng)物感到疼痛并甩動(dòng)尾巴時(shí),傳感器會(huì)檢測(cè)到它,停止反應(yīng)時(shí)間計(jì)數(shù)器并關(guān)閉燈泡。動(dòng)物的反應(yīng)時(shí)間因此自動(dòng)確定為接近的 0.1 秒(除非手動(dòng)評(píng)分選項(xiàng)被激活,在這種情況下,科學(xué)家通過按下腳踏開關(guān)停止計(jì)數(shù)器)。
- 延遲時(shí)間和強(qiáng)度會(huì)自動(dòng)導(dǎo)出到記憶棒。包括 U 盤和軟件!
