甩尾測(cè)痛儀儀器簡(jiǎn)介:
甩尾測(cè)痛儀測(cè)量大鼠對(duì)輻射能反應(yīng)時(shí)間,輻射來(lái)自150瓦光源。甩尾測(cè)痛儀使用一臺(tái)拋物面反射器將射線集中于大鼠尾。光源的能量可以調(diào)節(jié)并能夠顯示能源利用的百分率。為鎮(zhèn)痛藥物療效迅速出現(xiàn)多使用大鼠.
甩尾測(cè)痛儀 的詳細(xì)介紹
甩尾測(cè)痛儀測(cè)量大鼠對(duì)輻射能反應(yīng)時(shí)間,輻射來(lái)自150瓦光源。使用一臺(tái)拋物面反射器將射線集中于大鼠的尾巴。光源的能量可以調(diào)節(jié)并能夠顯示能源利用的百分率。為鎮(zhèn)痛藥物療效迅速出現(xiàn)多使用大鼠.
光學(xué)傳感器置于聚焦的光源之下。鼠應(yīng)該放置在合適的位置上,使它的尾巴遮暗從傳感器聚焦的光源。當(dāng)系統(tǒng)開(kāi)始時(shí),使用提供的腳踏開(kāi)關(guān)或面板上的啟動(dòng)鍵,光源照亮和計(jì)時(shí)器以十分之一的秒速度計(jì)數(shù)。當(dāng)大鼠的尾開(kāi)始甩動(dòng)時(shí),表明它的痛苦開(kāi)始,漏出傳感器。甩尾運(yùn)動(dòng)關(guān)閉了計(jì)時(shí)器和光源。反應(yīng)時(shí)間可直接地從顯示器上讀取,精確到秒或十分之一秒。一個(gè)標(biāo)準(zhǔn)并行端口允許與打印機(jī)的連接記錄試驗(yàn)數(shù)據(jù)、能級(jí)和反應(yīng)時(shí)間。定標(biāo)設(shè)施允許在開(kāi)始實(shí)驗(yàn)之前將光源設(shè)置到期望水平。
This meter measures a rat’s reaction time to radiant energy,from a 150 watt light source. The beam is focused on its tail usinga parabolic reflector. The energy of the light source can beadjusted and the display indicates, as a percentage, how muchenergy is being utilized
An opticalsensor is located underneath the focused light source. The ratshould be positioned such that its tail obscures the focused lightsource from the sensor. When the system is started, either usingthe supplied footswitch or front panel mounted start key the lightsource illuminates and a timer starts counting in tenths of asecond. When the rat’s tail flicks, indicating its pain threshold,it uncovers the sensor. This tail movement turns off the timer andlight source. Reaction time can be read directly from the displayin seconds and tenths of a second.
A standard parallel port permits connection to a printer to recordthe trial number, energy level and reaction time. A calibrationfacility allows the light source to be set to the desired levelbefore commencing with the experiment.
