Universal thermo-sensitivity stimulation instrument

Abstract

The invention discloses a universal thermo-sensitivity stimulation instrument which comprises a base and a universal support. The universal support is mounted on the base and comprises a first upright column and a second upright column, sleeves are arranged on the first upright column and the second upright column, positioning bolts are mounted on the sleeves, and the sleeves are provided with hoops via fixing supports; the sleeves include a first sleeve and a second sleeve, the first sleeve sleeves the first upright column, the second sleeve sleeves the second upright column, the second upright column is mounted in the hoop on the first sleeves, a light source system is mounted in the hoop of the second sleeve, the second upright column and the light source system are mounted in the corresponding hoop, and the second upright column can slide along the axial direction of the first upright column and can rotate at optional angles in a plane where the second upright column is located; the light source system can slide along the axial direction of the second upright column and can rotate at optional angles in the direction perpendicular to the plane of the second upright column. The universal thermo-sensitivity stimulation instrument has the advantages that movement and rotation of the first upright column are combined with each other, accordingly, light sources can be adjusted at optional angles, the height can be adjusted, the thermo-sensitivity of optional regions of experimental animals can be measured, and the field of research on the thermo-sensitivity can be broadened.

Description

technical field [0001] The invention belongs to the field of medical experimental instruments, in particular to a universal heat-sensitive stimulator. Background technique [0002] Currently, bolometers are commonly used to measure thermal hyperalgesia in experimental animals. Many laboratories use the equipment of IITC Company of the United States to measure the thermal allodynia of experimental animals. IITC’s equipment mainly controls the final output radiant heat intensity through the light source controller, and manually moves the focal point of the light source under the glass plate to the receptive field (plantar center) of the tested animal. However, the main technical defects of this type of equipment are as follows: [0003] 1. The animals need to be placed on a glass plate, and only the soles of the experimental animals can be measured, but not the receptive field area except the soles of the feet; [0004] 2. The light source of the original device can only mo...

AI Technical Summary

Problems solved by technology

[0003] 1. The animals need to be placed on a glass plate, and only the soles of the experimental animals can be measured, but not the receptive field area except the soles of the feet;

[0004] 2. The light source of the original device can only move horizontally under the glass plate, and the position cannot be adjusted arbitrarily, which limits the measurement of thermal sensitivity of the area of ​​interest outside the sole of the foot by researchers
