Embodiment 1

[0023] Embodiment 1 A kind of special insole preparation suitable for diabetic patients

[0024] Prepare each experimental group and control group according to the composition of the special insole of table 1, prepare the special insole suitable for diabetic patients, each experimental group and control group are prepared by the following methods:

[0025] a. adding the active factor into the silk fibroin solution to form silk fibroin solution A containing the active factor;

[0026] b. Silver ions are added to chitosan or its derivatives to make solution B;

[0027] c. The solutions A and B are blended by a high-voltage electrostatic method to make a blended yarn, which is woven into a blended silk fabric C;

[0028] d. Dissolve water-soluble sugar compounds and water-soluble polymers in water, add organic acid or alkali, react at 200-300°C, add copper ion solution, and dehydrate to obtain carbon airgel D containing copper ions.

[0029] e. Composite the blended silk fabric...

Embodiment 2

[0034] Use effect and satisfaction evaluation of embodiment 2 special insoles

[0035] (1) Use effect evaluation

[0036] 60 diabetic patients were randomly divided into 12 groups, 5 in every group, the special insoles made by each experimental group and control group in the trial embodiment 1 on the right foot for 4 weeks, and the common insoles were applied on the left foot. Compare, observe the foot lesions, and give an evaluation of the use effect. The use effect score is divided into 10 grades from 1 to 10. The higher the value, the better the protective effect of the special insole on the diabetic foot.

[0037] (2) Satisfaction Evaluation

[0038] 60 diabetic patients were randomly divided into 12 subgroups, with 5 people in each group, and tried on the special insoles made by each experimental group and control group in Example 1 for 4 weeks. A comprehensive score is given for wear resistance, sweat absorption, heat retention, antibacterial and deodorizing capabilit...

Abstract

The invention provides a special foot pad suitable for a diabetic foot, and a preparation method thereof. The special foot pad is of a foot engineering structure, and is formed by an A layer and a B layer fitting tightly, wherein the A layer faces a shoe sole and is formed by carbon aerogel containing copper ions; the B layer faces a sole and is formed by a blending silk fabric formed by silk fibroin, chitosan, active factors and silver ions. The special foot pad suitable for the diabetic foot provided by the invention has high moisture absorption, wear resistance, corrosion resistance, heat preservation, moisture resistance, antibiosis, deodorization, and blood glucose reduction, and is beneficial to repair of the diabetic foot.

Description

technical field [0001] The invention relates to a special insole for medical care, in particular to a special insole for protecting the feet of diabetic patients. Background technique [0002] Diabetes is a disorder of hyperglycemia due to insufficient secretion of insulin. The patient's early symptoms are not obvious, followed by polydipsia, polyuria, hunger and hyperphagia, fatigue and weight loss, and itchy skin. Clinically, seven years after the onset of diabetes, the risk of "diabetic foot" will occur. [0003] Diabetic foot is divided into wet gangrene, dry gangrene and mixed gangrene. (1) Wet gangrene is a relatively common necrosis of the foot in diabetic foot disease. Due to the hardening of the blood vessels and the formation of plaques in diabetic patients, the branch nerves are damaged, the blood vessels are easily occluded, and the microcirculation is damaged, and the metabolites of necrotic tissue cannot be discharged. Swelling, and some feet develop a dark...
