El uso de dispositivos medicos en el hogar, originalmente disenados para uso hospitalario, ha aumentado. Su uso es complejo e inseguro debido a la inexperiencia del usuario y el entorno no controlado. El objetivo de este estudio es evaluar la seguridad en el uso de este tipo de dispositivos a traves de la creacion de un modelo conceptual que identifica los riesgos que podrian surgir para un grupo de usuarios inexpertos que los operan. A traves de unestudio de usabilidad y siguiendo la metodologia Grounded Theory se identificaron problemas y errores que emergen a traves del uso en el hogar de dos dispositivos medicos distintos con la finalidad de crear un modelo conceptual. El modelo conceptual obtenido es representado en una herramienta de evaluacion, que permite a los interesados identificar el dispositivo medico mas apropiado para un usuario especifico, detectando las debilidades que pueden llevar a un uso inseguro. La herramienta creada efectivamente permite detectar las caracteristicas de riesgo, considerando cada situacion particular de uso. Abstract: The use of medical devices in the home environment, originally designed for hospital use has increased. Its use is complex and uncertain because of the inexperience of the lay user and the uncontrolled environment. The objective of this study is to evaluate the safety in the use of these devices through the creation of a conceptual model that identifies the risks that could arise for a group of lay users who operate them. Through a usability study and following the Grounded Theory methodology problems and errors were identified emerging through the home use of two different medical devices in order to create a conceptual model. The conceptual model obtained is reified as an evaluation tool that allows stakeholders to identify the most suitable medical device for a specific user, detecting the weaknesses that may lead to an unsafe use. The evaluation tool created effectively allows detecting risky characteristics, considering the particular situation of use.
