Description

Foot decompression pad

Technical Field

The invention relates to the technical field of diabetic foot nursing, in particular to a foot pressure reduction pad.

Background

Diabetic foot is one of the serious complications of diabetes, often leading to non-traumatic amputation and even death. The latest edition of Chinese guidelines for the prevention and treatment of diabetic foot indicates that up to 8.1% of diabetic patients over 50 years old in China have diabetic foot, which means that the number of diabetic foot patients is large. Diabetic foot not only can cause devastating attacks on patients and families, but also can bring huge burden to society and national health care systems. Both domestic and foreign researches show that the treatment cost of the diabetic foot is high and accounts for about 1/3 of the total medical cost of the diabetes. Although significant progress has been made in recent years with respect to the pathogenesis and treatment of diabetic feet, the overall infection rate, amputation rate, and mortality rate of diabetic feet remain high. Meanwhile, the recurrence rate of ulcer of diabetic foot ulcer patients within 1 year after wound healing reaches 40%, and the recurrence rate within 3 years reaches 60%. For diabetic foot patients, early discovery, early prevention, early treatment and timely referral are particularly important.

Currently, reduced pressure treatment of diabetic feet is an important component of care and one of the basic treatment management strategies. The vast majority of plantar ulcers result from increased plantar pressure. Therefore, reduced pressure treatment is of paramount importance. Even after diabetic foot ulcers heal, care should be taken to enhance foot care in high-risk foot patients in order to prevent recurrence and new eruptions of the ulcers. The guidelines recommend wearing reduced pressure shoes as a primary prevention strategy. Through sole pressure analysis of diabetic foot patients, the parts with higher pressure can be identified, and insoles and treatment shoes can be further customized. Some prospective studies have shown that patients wearing reduced pressure treatment shoes can effectively prevent recurrence of ulcers. However, there is a gap between guideline recommendations and clinical practice, and custom insoles and therapeutic shoes are expensive, long in design cycle, low in patient acceptance, and poor in compliance.

Diabetic foot ulcers have a wide variety of pressure reduction modalities, such as total contact plaster braces (TCCs), braces, removable (RCWs) or non-removable walking braces (iTCCs), half-boots, modified surgical shoes, foot plasters, and various felt or foam dressings. The pressure reducing felt is one of the pressure reducing modes, and has the advantages of low cost, individualized pressure reduction according to the change of the pressure of the soles and high acceptance of patients. However, the existing pressure reducing felt on the market only exists as a pressure reducing mode, and changes of foot skin of a diabetic foot patient are ignored. The discomfort such as dry skin and poor elasticity easily appear on the soles of diabetic foot patients, and the dry skin easily causes new wounds when the pressure reducing felt is used, which is one of the main reasons for the limitation of clinical use.
