Description

Technical Field

[0002] Raynaud's syndrome is caused by sudden spasm of the arterioles at the ends of the fingers (toes) due to stimulation such as cold or emotional tension, which leads to pale skin and cyanosis at the ends of the extremities. Raynaud's syndrome can be divided into primary and secondary. Workers engaged in vibrating machinery operations may also suffer from secondary Raynaud's syndrome.

[0003] Usually, when Raynaud's syndrome occurs, the patient's fingers turn from gray to pale, progressing from distal to proximal with clear boundaries, which can last for several minutes to ten minutes, and then gradually turn from pale to flushed, and finally return to normal color. White fingers are an important indicator for diagnosing Raynaud's syndrome, and they occur sporadically. Patients may not show symptoms of white fingers when they seek medical treatment, making it difficult for doctors to diagnose, evaluate and treat them.

[0004] At present, cold water rewarming equipment is used to produce cold water of different temperatures through the refrigeration system. The patient places both hands in the water tank, soaks for five to ten minutes, then takes them out. The temperature change of the finger skin before and after the cold test and its recovery are measured by a thermometer, and at the same time, it is observed whether white fingers are induced. However, the existing method only induces through cold water stimulation, the inducing conditions are single, the probability of white finger symptoms is low, and the induction of Raynaud's syndrome is difficult.
