HOW NEGATIVE IS THE PRESSURE USED IN THE SURGICAL WOUND TREATMENT WITH NEGATIVE PRESSURE THERAPY ?
The study aims to assess the significance of negative pressure therapy in the treatment of surgical wounds and using the ANSYS simulation software for fluid dynamics calculation will give us the possibility to determine the fluid flow dynamics inside the vacuum kit during its use. Material and methods: To predict the speed, pressure and temperature of the fluid inside a vacuum kit, we used numerical modeling, using the finite element method, of the gas fluid flow phenomenon. Results: The pressure of the liquid fluid is higher in the area of contact with the wound, compared to the pressure of the liquid fluid in the outlet area of the capillary tube, accentuating with increasing pressure applied to the end of the tube. 32% of the fluid pressure at the interface between the sponge and the wound. Conclusions: The rate of pressure transmission inside the sponge is variable favoring the appearance of ischemia areas on contact with the wound.
