Embodiment 1

[0051] like figure 1 As shown, the present embodiment discloses a test system for animal electrical stimulation pain assessment, including a test cabinet 1 and a camera 2; wherein the camera 2 is used to obtain video information of animals moving in the test cabinet 2; specifically, the test cabinet 1 The top of the test cabinet is open so that operators can put animals, such as mice, into the test cabinet 1; specifically, the outer shell of the test cabinet 1 is transparent and made of plexiglass or polymer material.

[0052] Specifically, the internal space of test cabinet 1 is divided into active area 11, and the bright area 12 and dark area 13 that are arranged on both sides of active area, wherein between bright area 12 and active area 11, and dark area 13 and active area 11 are separated by movable partitions 10. The movable partitions 10 are made of plexiglass or polymer material and can move up and down along the inner wall of the test cabinet 1 to limit the activity a...

Embodiment 2

[0079] like Figure 4 As shown, this embodiment discloses an animal electrical stimulation pain assessment test method using the animal electrical stimulation pain assessment test system disclosed in Example 1, which includes the following steps;

[0080] S1. Place the subject animal in the activity area of ​​the test cabinet for activities, and control the conductive coating to generate current.

[0081] Specifically, the structure of the test cabinet is the same as that of the test cabinet in Embodiment 1, and will not be repeated here.

[0082] S2. Using a camera to obtain video information of the animal when it is in motion.

[0083] Specifically, the structure and function of the camera are the same as those of the camera in Embodiment 1, and will not be repeated here.

[0084] S3. Process the video information through the data processing device, analyze and obtain the activity track information of the animal, and analyze the activity track information according to the ...

Abstract

The invention discloses an animal electrical stimulation pain evaluation test system, which comprises an animal movement device comprising a limited area for animal movement, wherein the limited areais provided with a conductive coating layer capable of generating current; a video acquisition device used for acquiring video information when the animal passes through the limited area; and a data processing device used for processing the video information, analyzing the video information to obtain movement track information of the animal, and analyzing the movement track information according to a preset analysis rule to obtain the pain level of the animal at the specific position of the limited area. The invention also correspondingly discloses an animal electrical stimulation pain evaluation test method. According to the technical scheme, the pain sense of the animal stimulated by the current of the conductive coating layer can be effectively tested and quantified, rich research information is provided for animal pain research, the accuracy and sensitivity of an experiment are improved, experiment errors are reduced, and the objectivity of a pain test result is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of pain research, and mainly relates to an animal electrical stimulation pain evaluation test system and an evaluation test method. Background technique [0002] Pain is a common clinical symptom. Pain brings a lot of inconvenience and negative psychological impact to people's life. At present, clinical pain diagnosis methods are mainly based on the patient's subjective description of pain. There is no scientific evaluation method that can accurately quantify the pain value, and there are great differences in the accuracy of pain evaluation. [0003] Effective assessment and correct recognition are prerequisites for scientific assessment of pain. First, it is necessary to establish standards for pain perception threshold and the weakest pain intensity, so that each subject can independently respond to pain and complete a reliable and accurate subjective pain assessment scale. However, the subjective scale o...
