Analysis of the characteristics of new composite fixing splint for medical purpose

Objective: to conduct a comparative analysis of the new functional composite material for medical purposes [RF Patent № 182764 IPC B32B 15/01 C22F 1/00] and the existing polymer immobilization dressings. Material and methods: polylactide used as a frame for manufacturing composite fixing splints for medical purposes was chosen as the object of study. Phase and physical transitions of the polylactide under study were recorded on a differential scanning calorimeter DSC 204 F1 Phoenix (Netzsch, Germany). The study of the thermophysical characteristics of the samples was carried out on the dynamic mechanical analyzer DMA Q800 (TA Instruments, USA). Results: the study of the elastic-deformation characteristics of the composite fixing splint showed that the product can be prepared and applied to the patient at small, easily achievable temperatures, and its high stiffness under normal conditions gives it a stable competitive advantage over existing analogues. Conclusions: the authors have shown the possible relevance of a composite locking splint in immobilization for mass application.
