Overview

Harvard Instruments' pain gauges are divided into plantar pain gauges and tail flick pain gauges, and the China Technical Service Center provides professional and high-quality pre-sales and after-sales services Pain measuring instruments use different stimulation or measurement methods to evaluate the efficacy of analgesia, anesthesia, or swelling reduction. The Plantar Test is used to measure the response of rodents to infrared thermal stimuli. Focus the infrared light source on the bottom of the animal's foot, press the switch, wait for the animal to retract the test claw, and the instrument will automatically record the intensity and duration of the infrared light. Natural Gene Technology has professional technicians trained by manufacturers to provide you with professional and thoughtful technical services

Details introduction:

Hargreaves Test

The plantar pain meter is used to measure the response of rodents to infrared thermal stimulation. Focus the infrared light source on the bottom of the animal's foot, press the switch, wait for the animal to retract the test claw, and the instrument will automatically record the intensity and duration of the infrared light. The experimental data will be displayed on the LCD screen, and can also be imported into a USB drive or into a computer via a USB cable.

Although the pain tail flick and hot cold plate experiments are classic measurement methods for acute pain heat threshold, and these two experiments are still used in pharmacological research, they have some limitations. Both methods have not been applied in the study of behavioral responses to hyperalgesia.

Foot pain testing represents an experimental method that combines the advantages of all pain allergy tests. During the experiment, the test animals will not be restrained. Additionally, the recording of experimental data is automatically sensed by the instrument and its accuracy will not be affected by personnel factors.

We also have a Dynamic Plantar Anesthesiometer for measuring plantar pain

Divided into foot sole pain tester and tail flick pain tester

• For measurement of hyperalgesia to thermastimulation
in unrestrained animals
• Automatic detection of the behavioraend point
• Validity unaffected by repeated testing
• Greater bioassay sensitivity than other thermaor
mechanicatests
• Each animacan serve as its own control

The plantar pain meter (Hargreaves method) enables researchers to identify the response of unconstrained rats to external thermal stimuli under * * action. This system includes:

• Mobile infrared light source
A glass panel with a fixed enclosure for mice placed on it
• Controller

　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　
The plantar pain tester places the mouse in one compartment of a three compartment enclosure. After adapting to the environment, the infrared light source is placed under a glass plate, and the operator directly places it under the mouse's hind paw Adjust the buttons on the infrared generator to start the experiment and start the digital solid-state timer When mice feel pain, they will retract their paws Retracting the claws will cause a sudden decrease in the heat reflex, while cutting off the infrared light source and stopping the reaction timer The withdrawal reaction time can be calculated to almost 0.1 seconds When conducting experiments on multiple mice, conducting experiments in three chambers simultaneously can improve efficiency Every mouse in the cabinet is unrestrained Calibration can be performed by selecting the Heat Flux infrared radiometer 37300
