Cold/hot pain stimulation system

Abstract

The invention discloses a cold / hot pain stimulation system, which mainly solves the problem that the laser stimulation equipment in the prior art cannot refrigerate and is complex in operation and high in cost in a nuclear magnetic environment. The cold / hot pain stimulation system comprises a cold / hot stimulation head (1), a protective net (2), a heat radiation water tank (3), a water pump (4), a water storage tank (5), an embedded type control module (6) and an upper computer, wherein the cold / hot stimulation head (1), the heat radiation water tank (3), the water pump (4) and the water storage tank (5) are connected with each other in sequence to form a water circulation system through water pipes; the cold / hot stimulation head (1) is connected with the upper computer (7) through the embedded type control module (6); the embedded type control module (6) controls the cold / hot stimulation head (1) to stimulate human skin according to the stimulation temperature set by the upper computer; and the actual stimulation temperature and pain sensation scores are transmitted to the upper computer (7) for storage and display through the embedded type control module (6). The cold / hot pain stimulation system disclosed by the invention is easy in operation and safe in use, and can be used for studying the pain sensation and evaluating pain relieving effect in a nuclear magnetic environment.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an instrument for studying human pain threshold and pain tolerance threshold. It can be used for research on pain sensation in normal and strong magnetic field environments, evaluation of analgesic effect, and auxiliary diagnosis and treatment of pain patients by medical staff. Background technique [0002] At present, about 5.5 million people in the world suffer from cancer pain every day, and there are at least 100 million pain patients in my country. Pain, the most primitive suffering of human beings, has become a common concern of the global pharmaceutical industry. There are also more and more studies on the evaluation of pain perception research and analgesic effect in scientific research institutions. [0003] Pain research is a hot and difficult issue in the field of neuroscience. With the advancement of imaging technology, pain research has ushered in unprecede...
