Method and system for fabricating personalized decompression insole aiming at foot shape of diabetic

Abstract

The invention discloses a method and system for fabricating a personalized decompression insole aiming at a foot shape of a diabetic. The fabrication method comprises the steps that firstly, a three-dimensional model of a foot part of the diabetic formed when the patient stays still is acquired, a foot shape outline is extracted in the three-dimensional model and thus an insole outline plane graph can be determined; secondly, sole pressure data formed during the patient's motion is collected, and pressure intensity peak positions and high-pressure areas in the insole outline plane graph are determined according to the sole pressure data; and thirdly, pressure reduction processing is carried out to the high-pressure areas. The method for fabricating the personalized decompression insole aiming at the foot shape of the diabetic is characterized in that firstly, the three-dimensional model of the foot part formed when the patient stands still is acquired, so that the outline plane graph of the insole can be determined; secondly, the sole pressure data formed during the patient's motion is collected, and the pressure intensity peak positions and the high-pressure areas in the insole outline plane graph are determined; and finally, the pressure reduction processing is carried out to the high-pressure areas. Through static and dynamic processing, the insole aiming at the patient's foot shape can be obtained, and thus pressure reduction effects can be enhanced.

Description

technical field [0001] The invention relates to the technical field of making insoles, in particular to a method and system for making personalized decompression insoles for diabetic foot shapes. Background technique [0002] Plantar high pressure and long-term stress will cause foot muscle pain, and if you stay in this state for a long time, such as wearing high heels for a long time, the bones and muscles of the foot will be deformed, resulting in foot deformities. For healthy people, high pressure or long-term compression of the feet can lead to calluses; however, this state is more dangerous for diabetic patients. The main danger comes from peripheral neuropathy and peripheral vascular disease in the feet of diabetic patients. Peripheral neuropathy makes it difficult for patients to feel high pressure, so they cannot actively adjust the way of stress, which will cause serious pressure injuries and lead to ulcers. Peripheral vascular lesions lead to reduced blood flow in...

Problems solved by technology

[0004] However, the current insoles are only uniformly designed for the general foot shape, and cannot vary from person to person. However, the foot shape of diabetic patients changes, and the use of existing insoles cannot effectively achieve the effect of decompression.
