title: Experimental study of the hydrodynamic effects of irrigation suction drainage.
abstract: The function of irrigation suction drainage, as an additional method in the treatment of bone infection, is associated with hydrodynamic problems that can only be experimentally examined. The visualization of liquid movement in the experimental model was realized by adding a colored ink to the input drain of the drainage system. When only 2000 ml of liquid was used daily (80 drops/min), the ink penetrated the experimental cavity only through the most proximal holes in the input drain. It spread slowly and irregularly through the liquid in the experimental bottle, forming pocket deposits and leaving sediment. When 6000 ml of liquid was applied daily (240 drops/min), ink quickly penetrated the cavity through all holes in the drain, leading to turbulence and dispersing equally in the bottle. Decoloration of the model bottle was faster because the output drainage was more efficient. With an increased flow, i.e., with more liquid used in the drainage, a better result was achieved. This was manifested in a swift decoloration and rinsing of the cavity.
