甩尾測痛儀儀器簡介：
甩尾測痛儀測量大鼠對輻射能反應時間，輻射來自150瓦光源。甩尾測痛儀使用一臺拋物面反射器將射線集中于大鼠尾。光源的能量可以調節并能夠顯示能源利用的百分率。為鎮痛藥物療效迅速出現多使用大鼠.
甩尾測痛儀 的詳細介紹
甩尾測痛儀測量大鼠對輻射能反應時間，輻射來自150瓦光源。使用一臺拋物面反射器將射線集中于大鼠的尾巴。光源的能量可以調節并能夠顯示能源利用的百分率。為鎮痛藥物療效迅速出現多使用大鼠.
光學傳感器置于聚焦的光源之下。鼠應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。當系統開始時，使用提供的腳踏開關或面板上的啟動鍵，光源照亮和計時器以十分之一的秒速度計數。當大鼠的尾開始甩動時，表明它的痛苦開始，漏出傳感器。甩尾運動關閉了計時器和光源。反應時間可直接地從顯示器上讀取，精確到秒或十分之一秒。一個標準并行端口允許與打印機的連接記錄試驗數據、能級和反應時間。定標設施允許在開始實驗之前將光源設置到期望水平。
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.
