Clever new tool for getting the right jab

University of Southern Queensland student creates model for injection know-how

Do you know your intramuscular jabs from subcutaneous stabs? How to correctly give an injection is an absolute must-have skill for health professionals. 

This important staple of medical education has received its own booster of innovation with the creation of a new learning tool by University of Southern Queensland student Krystal Henry. 

The final-year biomedical science student translated textbook diagrams into a 3D model that outlined the ‘what lies beneath’ anatomy of an injection site alongside the various needle angles that different treatments require. 

The result is a visual learning aid that will soon find its way into the University’s nursing and health sciences laboratories. 

Senior Lecturer (Nursing) Dr Lisa Beccaria said her team took matters into their own hands to improve existing, standard models that were limited in what they provided.

“We searched online for alternative models but there really wasn't any out there that could help the students to see the underlying structures of the skin, or to show the needle angle to get to those underlying structures,” Dr Beccaria said.

“So that's when we made the decision to create something ourselves.” 

Dr Beccaria, working with Associate Professor (Biomedical Science) Kate Kauter, tasked Ms Henry with developing a model with University’s 3D printing expert Stephanie Piper (USQ Makerspace).

“Based on the brief and the possibilities with the modelling technology, I spent a lot of time poring over my medical textbooks and learning 3D printing software,” Ms Henry said.

“There were many factors to consider, such as building depth and dimension into 2D designs, while conveying relevant education information within the constraints of technology was the primary focus.

“It’s great that this will be useful to future students and I expect them to improve on this model (maybe even create a version that will allow fluids to be injected). This type of collaboration and use of technology can really benefit health education.”

The project was funded through the University of Southern Queensland Technology Demonstrators project.
