Problem Statement

We began our research by examining, testing and experiencing these existing devices used for dispensing liquid medicine for children.
Overall, these existing products have little to no affordances for children; it’s mainly about the perceived efficiency in operation by parents. Through tests and various interviews, we found areas for improvement concerning issues in usability, dosing accuracy, and patient comfort.


We worked with both new and experienced parents, practicing pediatric professionals,
and some toddlers to test our various stages of ideas and physical prototypes.


Prototyping + Model Process

We decided that primarily plastics silicons were what we needed: 
by experimenting with different types of the material and forms, we were able to utilise the flexible material
for and easy squeeze mechanism for a more child-friendly delivery system.


Final Prototype


Why Two Chambers?

We found that parents and professional nurses often already accompany their children's medicine delivery routines with a flavoured juice or flavoured liquid to mitigate the bitter flavour of medicines. This duo chamber delivery system emphasizes placing the child's medicine experience first.

Younger children below the age of 4 also taste flavours much more intensely than adults around this period of growing up. Therefore, bitter flavours are perceived much more bitter than later in life.


Why Self-Administration?


Parent Assisted




In our testing phase, we found that having another person feed a patient induces more negative experience; something about
not being able to control the situation made even delivering a tasty concoction frightening.  Our design allows the child to more easily self-administer to allow the child to have a greater sense of control in their medicine intake routine.

Ideally, the child self-administers. However if this is not possible, a parent or guardian can also administer for the child.


Measurement Graphics

Final Presentation (13).jpg

One side of the device has graphical elements for easy use for the parent; it shows both ml and tsp so no conversions are necessary.

As for the other side is a less informational graphic. We wanted to have it be more of a fun distraction for the child; this design allows the child to follow the flow of the liquid diagonally from side to side.
