Introduction
More and more people, especially elderly, have complex medication disciplines, with a whole range of different medicines. It is important to take the right medicines, in the right dose, at the right time. Missing a dose or taking more medicines than necessary could lead to dangerous situations, but also taking medicines that don’t go together at the same time, may have negative consequences. In 2013 almost 49,000 people older than 65 were admitted to the hospital because of wrong medication use, of which 48% could have been prevented (‘Vervolgonderzoek Medicatieveiligheid’). A system that would remind the user to take his medicines and dispenses the right medicines at the moment they have to be taken, would prevent a big part of these situations. The electronic devices and internet connection in your house provides extra possibilities for such a system. Therefore we want to design a smart system that dispenses medicines. This system will have the basic function of a medicine dispenser: dispense the right medicines and notify the user if he/she has to take his medicines by an alarm. However, because it will be connected to the internet, there are extra possibilities for notifications on smartphone and an automatic update of the medication discipline if the doctor’s prescription changes. This wiki page will describe our project, including state-of-the-art, literature research, and the design process.
- Goals
- Design a simple and safe medicine dispenser
- Easy to use, especially for elderly and disabled
- Smart; uses internet of things
- Secure
- Easy to refill
- Challenges
- What are critical parts of the system?
- What functions should the design include?
- What will the interface look like?
- Who is responsible if something goes wrong?
- How to design a dispenser that doesn't jam?
- How will the device function without an internet connection?
- How is it refilled?
- Will this increase the workload of doctors?
- Approach
- Conduct a literary study of existing technology to achieve our goals and solve our challenges
- Design the prototype
- Build the prototype
- Program the prototype
USE Aspects
We've regocnized these USE groups relevant to our design:
User: Doctors, Pharmacists, Patients
Society: Elderly, Disabled people, Elderly care workers, Medical Institutions, Family of users
Enterprise: Pharmaceuticals
State of The Art
Planning
This part describes a general planning of our project, including important milestones.
Week 2
- Literature study (state-of-the-art)
- Define objectives + deliverables
Week 3 + Carnaval holiday
- Determination of all functions of the robot (pill dispenser)
- Designing the pill dispenser paper so we know what to order
- Determine what functions the prototype will have and how we will build it (materials, electronics, etc.)
- Literature study (continued)
- Start on software design
Week 4
- CAD sketch (based on sketch on paper)
- Gathering + ordering parts needed for the dispenser prototype
Week 5
- Finish software, build prototype
Week 6
- Finish prototype
Week 7
- Test prototype
Week 8
- Final presentation
- Finish wiki
Every week
- Update wiki with project and design progress, including description of the state-of-the-art and USE aspects.
