Resumo
Estudos recentes da IDF (International Diabete Federation) mostram que 9,3% da população mundial sofre com diabetes, que é caracterizada pela falta de insulina ou a inabilidade das células a reagir com a insulina. Atualmente, as bombas de infusão de insulina presentes no mercado são equipamentos importados com custos de aquisição em torno de US$4,500.00 e altos custos de manutenção. Buscou-se desenvolver um simulador de uma bomba de infusão de insulina de baixo custo que seja capaz de representar todas as operações e funções de um equipamento real com alta confiabilidade e fidelidade, com o objetivo de auxiliar a elicitar os requisitos funcionais e refinar a arquitetura para um protótipo. Esse sistema foi inteiramente construído via software, por meio da linguagem de programação Java. Por se tratar de um dispositivo médico, a operação de controle deve ser robusta o suficiente para garantir as dosagens corretas do medicamento sem falhas. O simulador desenvolvido passou por testes de usabilidade com uma amostra de 34 usuários participantes. Utilizando o formulário padrão SUS (System Usability Scale), encontrou-se uma pontuação de usabilidade média de 67,43. O resultado encontrado é satisfatório considerando a natureza do sistema desenvolvido, e pode ser melhorado com treinamento adequado dos usuários e acompanhamento clínico, o que se espera na utilização de um equipamento real. O uso de um simulador durante o desenvolvimento de um protótipo de uma bomba de infusão de insulina traz diversos benefícios, contribuindo para um sistema mais robusto e bem estabelecido. Espera-se, para trabalhos futuros, que esse modelo de software possa ser capaz de ser transferido para o hardware de uma bomba de infusão de insulina, visando, dessa forma, o tratamento e melhoria da qualidade de vida de uma grande parcela da população que sofre com a doença.
Recent studies from International Diabetes Federation (IDF) show that 9.3% of the entire world population is affected by diabetes, which is characterized by a lack of insulin or the inability of cells to react to insulin. Currently, insulin infusion pumps available on the market are imported equipment, with purchase costs around US$4,500.00 and high maintenance costs. We aim to develop a low-cost insulin infusion pump simulator capable of representing all of the operations and functions that would be found in a real equipment with high reliability and fidelity, in order to help elicit the functional requirements and refine the architecture for a prototype. The system was built entirely via software, using Java programming language. As a medical equipment, the control operation must be stable to ensure the correct dosage of the drug without fail. The developed simulator underwent usability tests with a sample of 34 participating users. Employing the standard questionnaire System Usability Scale (SUS), we found an average usability score of 67.43. The result found is satisfactory considering the nature of the system developed, and this can be improved with proper training of users and clinical follow-up, which would be expected when using the real equipment. The use of a simulator during the development of a prototype of an insulin infusion pump brings several benefits, contributing to a more robust and well-defined system. We expect for future projects, to implement the simulation model developed in the insulin infusion pump prototype afterwards, thus we aim to progress towards the improvement of the life quality and treatment of a large portion of the population suffering with the disease.
