Bioactive functional dressing for treating diabetic feet

Abstract

The invention discloses bioactive functional dressing for treating diabetic feet. The dressing comprises a bioactive functional layer, an antibacterial functional layer, a fluid absorption functional layer and a biotic pressure functional layer sequentially from the bottom up. The dressing is simple in structure and low in production expense, low in cost and convenient to operate at the same time, greatly facilitates treatment of diabetic foot wounds of a doctor and medical care personnel; an active ingredient of the bioactive functional layer has a slow release effect; the dress can effectively stimulate and promote cell activation and regeneration of the surfaces of the diabetic foot wounds and promotes capillary network and nerve repair of the surfaces of the wounds by the action of the biological active ingredient. The dressing has effects of repairing neural and vascular lesions, efficiently resisting infection, absorbing fluid and evacuating pus on the surfaces of the wounds, and a biomechanical effect on the wounds, is multifunctional and good in treatment effect and can be widely applied to clinical treatment and nursing of the diabetic feet.

Description

technical field [0001] The invention relates to a functional dressing in medical equipment, in particular to a bioactive functional dressing for treating diabetic foot. Background technique [0002] With the development of the economy, the change of people's lifestyle and the aging population, the number of diabetic patients (mainly type 2 diabetes) is increasing rapidly, presenting an epidemic trend. According to a report from the World Health Organization, in 2013, 382 million adults around the world suffered from diabetes. Diabetes has become a common and frequently-occurring disease in many countries around the world, and its mortality rate ranks third after cardiovascular diseases and tumors. [0003] Compared with developed countries, the prevalence of diabetes in my country is still relatively low, but the rate of increase in the prevalence of diabetes in my country is the fastest in the world. Coupled with our large population base, the number of people with diabetes...

AI Technical Summary

Problems solved by technology

[0018] (1) It is not considered comprehensively that diabetic foot is a complex result of vascular disease, neuropathy, impaired immune function and infection, and its complexity, while existing inventions or products only consider one or two functions, such as only Simply introduce growth factors, or add antibacterial, or add liquid absorption, etc., so the comprehensive effect is not good;

[0019] (2) All inventions do not take into account the condition of nerve damage, so the dressing does not take corresponding functions;

[0020] (3) Some dressings use chitosan as an antibacterial material. In fact, simple chitosan is effective against Gram-negative bacteria, Pseudomonas aeruginosa and drug-resistant Pseudomonas aeruginosa, Pseudomonas aeruginosa, and Candida albicans. , anthrax and other effects are not significant enough to really play an anti-infection role;

[0021] (4) There are very few domestically produced high-end functional dressings, which cannot meet the huge demand of the market;

[0022] (5) The prices of dressings used clinically by foreign companies in China are generally high
