Inducing device for Raynaud syndrome

Abstract

The invention provides an inducing device for Raynaud syndrome, and relates to the field of inducing devices. The inducing device for the Raynaudsyndrome comprises a main machine shell, a vibration exciter system and a refrigerating system, wherein the vibration exciter system comprises a vibration excitation structure and a vibration rod, and the vibration excitation structure is in transmission connection with the vibration rod; and the refrigerating system comprises a refrigerating structure and an air supply structure, wherein the main machine shell is provided with cold air openings facing the vibration rod, a cold air channel is arranged between the refrigerating structure and the cold air openings, and the air supply structure is mounted in the cold air channel. The inducing device adopts combined design of the vibration exciter system and the refrigerating system, during testing, the hand of a patient holds the vibration rod, low-temperature airflow is blown out towards the hand of the patient through the cold air openings, the refrigerating system stimulates the hand of the patient through low temperature and cold air, and the vibration exciter system simulates the working scene of vibration mechanical operation. The vibration stimulation conditions are further increased, the white finger induction probability is improved under multiple stimulation conditions, and the induction success rate of the Raynaud syndrome is ensured.

Description

technical field [0001] The invention relates to the technical field of inducing devices, in particular to an inducing device for Raynaud's syndrome. Background technique [0002] Raynaud's syndrome is caused by stimuli such as cold or emotional stress, causing sudden spasm of arterioles at the end of the fingers (toes), and then pale skin and cyanosis of the extremities. Raynaud's syndrome can be divided into primary and secondary, and workers engaged in vibrating machinery may also cause secondary Raynaud's syndrome. [0003] Usually, when Raynaud's syndrome occurs, the patient's fingers change from gray to pale, and develop from distal to proximal with clear boundaries, which can last for several minutes to ten minutes, and then gradually change from pale to flushed, and finally return to normal color. As an important indicator for the diagnosis of Raynaud's syndrome, white fingers have the characteristics of occasional onset. Patients may not necessarily show white finge...
