Objasnění destrukčního vlivu gravitačního setu v infuzní pumpě

Abstract

Intravenous therapy is currently one of the most common operations performed in health care facilities, finding its use in a wide range of cases. The particular process of treatment can be implemented in two ways - using gravity-fed infusion and by use of volumetric infusion pump. The principle of infusion controlled by a volumetric pump lays specific demands on the quality of the infusion sets in use. When warranting the flow rate accuracy it is necessary to ensure suitability of the set for use with the pressure method. However, there are a number of risk factors in common medical situations, whose influence may lead to violating the terms of compatibility and the subsequent use of a volumetric pump with an improper administrative set made only for gravity-fed infusion. The aim of the first part of this work is the theoretical determination of the possible destructive effects of the infusion pump to the material of a gravity-fed administration set based on the evidence about the negative impacts of the pump on the flow rate accuracy and mechanical characteristics of the infusion sets. The goal of the second part is an effort to proof the negative impact of the mechanical stress of a gravity set in an infusion pump to dosage accuracy and the material properties of the used set through experimental data.
