Embodiment

[0035] A method for quantifying mechanical pain testing such as figure 1 , including the following steps:

[0036] S1. Perform detection positioning, set the pain test device on the subject's test area, such as the skin or mucous membrane, and direct the detection port 5 of the test shell 1 towards the test area, and the test shell 1 does not touch the subject's test area. test area;

[0037] S2. Prepare m test cores 2 with sequentially increasing stimulus intensity, that is, test cores T1, T2, ..., T k-1 , T k , ..., Tj, ..., Tm, use the test core 2 with the smallest stimulus to test the subject; The smaller the intensity is; the stimulation intensity of the test core is positively correlated with the detection pressure and hardness value, and negatively correlated with the diameter of the detection end face.

[0038] S3. Within the set time, stimulate the test area of ​​the subject through the self-gravity of the test core 2, and select test cores with increasing stimula...

Abstract

The invention provides a quantitative mechanical pain testing method and device. The quantitative mechanical pain testing method comprises the following steps: through detection and positioning, preparing m test cores with sequentially increasing stimulation intensities, and stimulating a tested area of a subject through the self gravity of the test cores within a set period, namely alternating stimulation increase step by step and stimulation decrease step by step until the total number of recorded first pain values and second pain values reaches a set number. According to the quantitative mechanical pain testing method and device, the pain threshold value of the local area of the subject under external force pain stimulation can be visually quantified, the operation is easy, and the testing is convenient. Furthermore, the stimulation intensity can be changed by replacing different detection tips through the detachable detection tips.

Description

technical field [0001] The invention relates to a method and device for quantifying mechanical pain testing. Background technique [0002] Mechanical pain is the mechanical deformation of tissues under the action of external force. When the degree of deformation exceeds the threshold of mechanical nociceptors, the receptors are activated to produce mechanical pain. After the external force is removed, the tissue reshape and the pain disappears. Pain is a common clinically unpleasant sensory and emotional experience. In medicine, pain is a symbol of danger, and has been identified by the World Health Organization as the five vital signs alongside breathing, pulse, blood pressure and body temperature. [0003] Currently, pain levels are generally used to describe pain, for example, level 0 means no pain, level 1 means mild pain, and level 10 means severe pain. In clinical research, it is usually verbal questioning by medical staff to obtain the subject's subjective pain lev...
