A Smart Insulin Pen
Diabetes Mellitus is a chronic disease that is increasingly prevalent in our society reaching both sexes and all ages. It is a disease characterized by increased levels of sugar (glucose) in the blood, hyperglycemia. Globally, in 2015, the estimated prevalence of diabetes was 415 million people with the disease estimated to reach 642 million by 2040. In 2015 the estimated prevalence of Diabetes in the Portuguese population aged 20-79 (7.7 million individuals) was 13.3%, that is, more than 1 million Portuguese in this age group have Diabetes. More than a quarter of people between the ages of 60-79 have Diabetes. The persistence of a high level of blood glucose, which is a characteristic of Diabetes, even when no Diabetes symptoms are present to alert the individual to it or to their decompensation, results in tissue damage. In virtually all developed countries, diabetes is the leading cause of blindness, kidney failure, and lower limb amputation. (Source: Diabetes factos e números 2016) This project is focused on the development of proposals to help people that need to administer themselves Insulin to use the right doses. As loosing vision capabilities one of the consequences of the disease, people may tend to reach blindness levels such that they cannot see the selected number of doses in insulin pens. The same is true for totally blind people. Although the patients may count the number of clicks, this may not be easy when the required doses are high so is the number of clicks to count. The work to develop consists in the study of possible solutions for augmenting the security of self-administration of insulin by modifying the insulin pens or create devices that will be used in conjunction with them. These devices must be Internet connectable to enable the administration history log to be consulted by doctors or caregivers. And, should have voice feedback to help the users to know what dose is selected prior to the administration.
- Study on the potential users of the technology to be developed: age, sex, handicap levels, needs, technological openness and literacy.
- Initial requirements analysis and definition
- Create 3-4 initial propositions for different devices or modifications to the current pens.
- Evaluate each of the proposed solutions in terms of usability and requirements observation.
- Chose one or two solutions to be evaluated by users using functional prototypes
- Implement the prototypes
- Perform complete evaluation with analysis and synthesis of the results.
