Development of a Low-Cost Insulin Infusion Pump Simulator:A Case Study with a Brazilian Company

Abstract

Purpose The purpose of this paper is to present and illustrate the development of a low-cost insulin infusion pump simulator. Methods: The simulation was written entirely using Java programming language, reproducing the appearance and functions of a low-cost insulin infusion pump. Later, the participants were invited to participate in a remote session and based on the results of a standard usability scale (SUS), it was possible to draw the assessment and check the system’s readiness. Results: By means of a sample size of 34 participants with different levels of knowledge on diabetes and infusion pumps, we found an average SUS score of 67.43, which is not directly linked to previous knowledge of the users. Conclusion: Although the insulin infusion pump is a complex and highly dedicated equipment, and its system may seem unfamiliar at first, the usability score found is satisfactory and with proper training and clinical support it may be improved, enabling the equipment to fulfill its purpose efficiently. Significance: The use of a simulation model during the development of an insulin infusion pump prototype may bring some benefits, paving the way for a well-defined, robust and safe system, improving the delivery of health care technologies and increasing patient safety.
