The present work aims to characterize a problem encountered in a production line of linear peristaltic infusion pumps, with the use of a software capable of interpreting experimental data by means of  statistical analysis. The problem was verifying for the maximum pressure of equipment, which does not attempt the product specifications, which can cause a free flow and can lead to death of the patient that may eventually come to use the equipment. This characterization was performed through experiments where we evaluated the influence of each component in the maximum pressure in the system (reflux), which there is a specification of a minimum and maximum value for their compliance. Various settings for the equipment were assembled by varying a specific part and fixing the other, thus obtaining several reflux pressure responses. After all the data collection, analyzed by MINITAB statistical analysis software collected data, obtaining the most critical piece, where due to some variation of this would be a great influence in the variable pressure reflux. It was generated a regression line with all these components and their influences, and the maximum pressure in response inserted in the straight configuration. So, it was possible to experimentally validate this straight and analytically and reset the specifications of each component considering any variation in scope of delivery or type of piece, ensuring that equipment develop its function safely and appropriately.
