Abstract
Objective: to study the physical and mechanical properties of two-component spongy hemostatic implants. Materials and methods. Experimental group of two-component sample №1 based on Na-CMC was compared with samples: №3 Surgicel, №2 Tachocomb. To determine the residual strain, the specimens were compressed followed by fixation of the thickness recovery. To determine sorption capacity, the sample was weighed, placed in distilled water, transferred to a prepared test tube, centrifuged, and the sponge mass was measured. Porosity was determined in the same sequence, but the implants were immersed in orthoxylene. To determine adhesion, specimens were placed between two plates and the force of separation of the implant from the surface of the plate was recorded. Results. The porosity coefficient of specimen №1 was greater than №2 and №3 by 0.61 and 0.87. Adhesive properties of sample №1 are 0.28 greater than №2 and 0.45 greater than №3. The sorption capacity per unit mass of sample №1 is 2.5 times greater than №2 and 2.47 times greater than №3. The residual strain values of sample №1 and №2 were 1.18 and 2.87 less than №3. The values of sample №1 were higher than №2 by 1.69.
