压痛仪根据Randall-Selitto理论设计,是进行压爪实验的经典仪器。实验时,将啮齿类动物的爪置于圆柱形底座,操作员踩压脚踏板,其上方的圆锥形推进器往爪上施力。当受试动物开始挣扎时,操作员松开脚踏板板,读取刻度值,其表示受试动物的疼痛值。压痛仪的显著特征是配备了一个低电压同步电动机。
现在也有可用于小鼠的版本37216,压力值降低50%,另新增一个推杆。

The Basile Analgesy-Meter has been designed to perform rapid precise screening of an-algesic drugs on the normal and inflamed rat paw, according to the Randall-Selitto test.
The instrument is basically a device which exerts a force increasing at a constant rate (a certain number of grams per second). This force is continuously monitored by a pointer moving along a linear scale.
The force is applied to the animal’s paw, which is placed on a small plinth under a cone-shaped pusher with a rounded tip. The plinth is made of TEFLON, which is biologically inert and has a very low friction coefficient. Thus, if the animal suddenly withdraws its paw, it slips out easily without being injured.
The operator depresses a pedal-switch to start the mechanism which exerts the force.
When the rat struggles, the operator releases the pedal and reads off the scale the force at which the animal felt pain.
