Biomechanics – Experimental Determination of Critical Force Needed for Cannula to be Torn out

Abstract

The aim of this paper is to determinate critical (tearing) force. This force is needed to be caused, for cannula and its securing fixation (in this case by tapes), to be torn out from patient’s body, (i.e. applications in medico-chirurgical branches). To determine this quantity, experimental approach was used, in which for more realistic approach real human cutis (skin) was used. Data acquired from this experiment may be later used in designing of a device for automatic winding of infusion tubes etc. Measurements were performed on porcine and human skin.
