Embodiment 1

[0036] a pain tester such as figure 1 As shown, it includes a metal stimulation head 1, a handle 2, a temperature display device 3, a constant temperature liquid circulation pump 4, and a constant temperature liquid tank 5. The metal stimulating head is made of copper spherical surface, and the inside is a hollow constant temperature liquid cavity. The metal stimulation head is connected to the constant temperature liquid cavity, the other end of the constant temperature liquid input tube is connected to the output port of the constant temperature liquid tank through the constant temperature liquid circulation pump, and the other end of the constant temperature liquid output tube is connected to the input port of the constant temperature liquid tank, and the constant temperature liquid fills the entire tube There is a temperature setting device and a heating wire in the constant temperature liquid tank. This tester performs a high temperature pain test.

Embodiment 2

[0038] In this embodiment, on the basis of Embodiment 1, the heating wire in the constant temperature liquid tank is changed to a semiconductor refrigeration chip (TEC2-19006 double-layer semiconductor refrigeration chip, Shenzhen Yileng Technology Co., Ltd.), such as Figure 4 As shown, it includes a metal stimulation head 1, a handle 2, a temperature display device 3, a constant temperature liquid circulation pump 4, a constant temperature liquid tank 5, a semiconductor cooling chip 6, an aluminum heat sink 7 at the hot end of the semiconductor cooling chip, and a heat dissipation device at the hot end of the semiconductor cooling chip device 8. This tester can perform low temperature pain stimulation test.

Embodiment 3

[0040] This embodiment is a combination of Embodiment 1 and Embodiment 2. The temperature setting device described in Embodiment 2 and the semiconductor refrigeration chip (TEC2-19006 double-layer semiconductor refrigeration chip, Shenzhen Yileng Technology Co., Ltd). The tester can switch between high temperature and low temperature pain stimuli.

Abstract

The invention provides a pain test instrument, which comprises a metal stimulating head, a handle, a constant-temperature liquid circulation pump and a constant temperature liquid box, wherein the constant temperature of the temperature probe is ensured through circulated constant temperature liquid, and the test stability and the test accuracy are improved. The paint test instrument has the advantage that a temperature sensing controller can be further additionally arranged, and the circulation flow speed of the constant temperature liquid is controlled according to the temperature difference value between the actual temperature of the stimulating head contacted with skin and the temperature of the constant temperature liquid, so the temperature regulation is faster and more intelligent.

Description

technical field [0001] The invention belongs to the field of medical devices, and in particular relates to a tester for accurately measuring temperature pain, especially cold pain. Background technique [0002] Pain is a major problem that seriously affects people's health. In the process of pain perception and conduction to the cerebral cortex, different damaged parts will produce different types of pain. Based on this, the theory of sensory nerve peripheral sensitization and central sensitization has been developed, and pain hypersensitivity and pain hypersensitivity are related to it. Corresponding with characteristic clinical signs. [0003] At present, domestic clinical practice mainly adopts medical history collection relying on the patient's self-description for such patients, and more nervous system examinations use palpation, pins and cotton wool (or feathers) to check the painful area to determine whether the pain is hyperalgesia Or hyperalgesia, determine the lo...
