Patient-specific medical compression stockings (MCSs) development based on mathematic model and non-contact 3D body scanning.

Medical compression stockings failed or didn't reach expected positive functions in practical uses, one of the reasons is related to the inaccurate or inappropriate of pressure distributions. Three-dimensional (3D) scanning and analysis were carried out to extract human anthropometric data. Knitting parameters were engineering designed and theoretical pressure profiles were predicted by mathematical models, according to integrative considerations of Standard, leg morphology and machine parameter setting. The predicted pressure distributions for Class I, II & III MCSs generally in predefined ranges. The actual measured pressure values were greater than predicted at all tested regions for Series 1 of MCSs. The MCSs combined structure A and B at calf region make the effect of homogenizing pressure around calf cross-section. It's feasible and valuable to develop MCSs based on knitting parameters, 3D body scanning individually and pre-defined pressure distribution ergonomically to match directly patient-specific medical requirements and healthcare.
