Towards a Framework for Investigating and Characterizing Syringe Injection Performance in Human Factors Studies
SessionPoster Session 2
DescriptionWith the prevalence of self-administered injections in the home environment increasing, the description and assessment of such injections becomes more pressing. Our work provides an approach to measure and characterize user performance during syringe injections with a focus on reusable syringes. The performance measurement platform is designed to quickly modify medication or syringe properties under evaluation for maximum assessment flexibility.
An effective injection force profile can be considered to be an approximate square wave. To characterize such profiles, we propose use of time and frequency domain approaches: Time domain assessments include average force, injection duration, rate of force changes, and the number of local maxima and minima. Frequency domain assessment describes the contribution of the various frequencies with an ideal square wave representing an infinite series of lines at the odd harmonics of the fundamental frequency and the amplitude at each harmonic declining with increasing frequency.
This work provides a novel methodological framework to analyze and characterize user performance during syringe injections, utilizing time domain and frequency domain analyses of force profiles. In combination with the newly developed measurement platform, it is possible to objectively assess performance and to facilitate decision-making in the development of user-friendly medical devices.
