玉研仪器 甩尾仪

热甩尾仪根据D"amour/Smith原理和方法，测量大鼠、小鼠尾巴部受红外热刺激时的痛觉阈值。

实验步骤及方法：

· 该仪器使用可调强度的红外光源，红外光通过一抛物镜面反射聚焦在实验动物的尾巴上；

· 操作人员将实验动物置于仪器上，把动物的尾巴放在红外光源处，接受热辐射刺激；

· 当动物感觉到疼痛时，尾巴会左右甩动或者轻敲台面，内置传感器会立刻检测到尾巴的活动，停止计时和关闭光源；

· 仪器自动记录反应时间和光源强；

· 数据可通过U盘或USB数据线导出到电脑；

· 该型号的设备在世界上使用和验证超过3000次，积累了数十年的经验；

型号：37560

主要特点：

· 尾部轻拍可自动记录或手动评分；
· 自动化程度高，避免人为因素引起的误差；
· 触摸屏控制，操控方便，显示直观；
· 可独立工作，也可连接电脑使用；
· 测试平台平整，表面无突出和遮挡部件；
· 可选配红外热辐射校准仪用于校准红外光源；
· 多种单位可转换；

· 该仪器适合大鼠和小鼠的测试；

· 有大鼠、小鼠两种不同的固定器可供选择；

仪器的操作
· 主机内包括红外光源、传感器、微控制器；
· 自动检测尾巴的活动情况，自动计时，延迟时间会被自动记录；
· 可选配倾斜的老鼠固定器，将老鼠尾巴保持在 45 度向上的位置。

可选配的小鼠固定器

控制面板

· 数据格式通用化，可使用其他软件进行统计；
· 带储存功能，用于实验数据的保存；

· 可联网，通过远程网络对实验方案进行编辑；

校准辐射计
· 用来对辐射强度进行校准；校准辐射计货号我37300；
·确保两个或多个装置提供完全相同强度的热伤害性刺激（辐射单位：mW/cm2）
· 测量红外光的能量的绝对值（1s持续时间内的1mW对应1mJ）
