The cold and hot plate pain measurement method is a commonly used method for pain screening and detection, as well as a method for determining and distinguishing the analgesic mechanisms of central and peripheral nerves. It has a wide range of applications. In the past, due to lax temperature control, inaccurate timing, and errors in personnel operation during use, the specificity of experimental results was often low. Based on the above problems, we have developed a rat and mouse cold and hot plate pain measurement instrument to solve the problems in the cold and hot plate method. It has received unanimous praise from experts and professors in trial and practical use.
The hot and cold plate pain meter for mice and rats is easy to use, with clear indicators, minimal tissue damage, and can be repeatedly used in animals. The pain response latency is long, making it easy to observe and measure small differences between them, compare the strength, speed, and duration of analgesic effects, and export detection data。
