Background

The dermatosis is related to skin diseases, is one of common diseases and frequently encountered diseases which seriously affect the health of people, and has the characteristics of high morbidity, high disability rate, strong infectivity, long treatment time and the like. With the increasing environmental pollution, the incidence of skin diseases is increasing. It is reported that the skin disease is a disease with the highest incidence, the highest disability rate and the strongest infectivity in human in the 21 st century historically. The data shows that the national dermatological drug market scale in 2018 reaches 167.31 billion yuan, which is a 4.3% increase on a par with the same. According to the research report on Chinese market assessment of skin disease drugs and investment direction (2018), it is shown that about 4.2 hundred million people suffer from skin diseases worldwide, wherein about 1.5 million patients exist in China.

More and more people suffering from skin diseases are concerned about symptomatic treatment. For example, cutaneous warts are a common cutaneous Human Papilloma Virus (HPV) infection, with an average prevalence of 3-13% in the population, and higher in children. Daily activities and quality of life can be significantly affected by local discomfort, restricted movement, etc. The common clinical treatment methods include freezing, electrocautery, laser surgery, external salicylic acid and the like, but the effect and the side effect are different. Generally, the cure rate is not more than 50%.

Comparative example:

the comparative example uses a metal wire electrothermal film as a heating chip to carry out a contrast experiment. Total 20 cases, 5 cases with abscission, and 15 final cases were analyzed. The number of the male patients is 11, and the number of the female patients is 4. The age is 20-30 years. The treatment was carried out at 42 ℃ for 40 minutes per day. The results showed that the overall remission rate was only 46.7% with 95% CI ranging from 21.3 to 73.5. During the treatment, 6 people feedback slight burning feeling, and no other side effect is observed. In contrast, the overall therapeutic effect of the far infrared device prepared by the method is obviously superior to that of a metal wire electrothermal film device.
