Description

Technical Field

[0001] The invention relates to an adjustable protective shoe suitable for patients with metatarsophalangeal joint deformity, belonging to the technical field of nursing appliances. Background Art

[0002] Primary gout is a group of heterogeneous diseases caused by long-term purine metabolism disorder, which leads to increased blood uric acid and tissue damage. It can manifest as clinical features such as acute and chronic arthritis, joint deformity and tophi. Its attacks often invade a single joint, and some of them occur in the first metatarsophalangeal joint, causing joint deformity.

[0003] Gout epidemiological survey data show that the prevalence of gout has been increasing year by year in recent years. The 2017 China Gout Status Report White Paper pointed out that the number of patients with hyperuricemia in my country has reached 170 million, of which more than 80 million are gout patients, and the number is increasing rapidly at an annual growth rate of 9.7%. It is estimated that by 2020, the number of gout patients will reach 100 million. Today, gout has become the second largest metabolic disease in my country after diabetes.

[0004] The top ten provinces with the highest number of gout patients are: Guangdong, Shandong, Hebei, Liaoning, Beijing, Jiangsu, Sichuan, Henan, Zhejiang and Hubei. Coastal areas and economically developed areas are high-incidence areas for gout. Based on the regional distribution, we can see that economically developed areas such as the Pearl River Delta, Bohai Rim, and the Yangtze River Delta are high-incidence areas for gout.

[0005] Gout "prefers" the first metatarsophalangeal joint. Pain in the first metatarsophalangeal joint is a typical manifestation of acute gout, and more than 90% of gout patients will suffer from repeated involvement of this part. In addition, this joint is a small joint in the body, and is frequently involved in daily activities such as walking and exercising. It is subject to the greatest force per unit area and is most susceptible to injury.

[0006] There is no shoe on the market that is suitable for "first metatarsophalangeal joint deformity". The deformity of the first metatarsophalangeal joint is not completely the same according to the size of the "tophus" in the joint cavity, and there are differences in their size and growth direction.

[0007] In the prior art, shoes are all customized or handmade, but the shoes on the market cannot adapt to patients with "first metatarsophalangeal joint deformity", and the uppers cannot be adjusted according to the different degrees of deformity of the "first metatarsophalangeal joint"; people who wear inappropriate shoes for a long time will have abnormal pressure on the big toe, thereby affecting the patient's daily work.

[0008] Therefore, it is necessary to design an adjustable protective shoe suitable for patients with metatarsophalangeal joint deformity to overcome the above-mentioned defects. Summary of the invention

[0009] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an adjustable protective shoe suitable for patients with metatarsophalangeal joint deformity.
