Autism occurs in infancy. Its clinical symptoms are mainly social disorder, communication disorder, interest limitation, etc., and are accompanied by different degrees of intellectual development disorders. Cao’s kite was carved by descendants of the Kong Xiangze family according to the kite binding method recorded in Cao Xueqin’s works. The kite contains the pursuit and yearning for a better life inside, and its external patterns and composition features are quite attractive. Therefore, the research applies the souvenir design of Cao’s kite visual elements to the treatment of autistic children for clinical auxiliary diagnosis and treatment.

The more obvious externalization of autistic children is their picky eating behavior. Therefore, 30 autistic children were taken as the research object, of which 18 children were still treated in the traditional way as the control group, and the other 12 children were treated as the experimental group using the souvenir design of Cao’s kite visual elements as an auxiliary way of diagnosis and treatment. The mental health status was analyzed by observing the behavioral changes in their diet. A total of three experimental interventions were carried out to calculate the average number of nausea and retching during the three intervention periods, and SPSS20.0 statistical software was used to conduct statistics and analysis of relevant data. The results are shown in Table 1.Table 1.

The number of retching after intervention in two groups of autistic children

The picky eating behavior of autistic children is manifested by their tolerance to food, which will lead to the physiological manifestations of nausea and retching. In the experimental results, the number of times of retching of children in the experimental group decreased except the number of eggs, among which the number of leeks, melons, dried beans, soybean milk and steamed bread decreased to zero; The control group showed an upward trend. The results show that the assistant diagnosis and treatment method designed by the souvenir of Cao’s kite visual elements is effective in treating children with autism.

In addition to the problems of autistic temperament, the diet and health of autistic children are also the focus of clinical attention. The effect of traditional diagnosis and treatment is limited, and the effect is not obvious. The souvenir design of Cao’s kite visual elements, as an auxiliary diagnosis and treatment method with visual impact, has strong appeal among children’s patients, and can effectively alleviate the symptoms of children’s autism.
