Open-Source And 3-D Printed Autoinjector, Anjutha Selvaraj

Undergraduate Student Research Internships Conference

Autoinjectors have become popular modern injectable medical devices used as drug delivery systems. Due to its ease, capability and reliability compared to other conventional injectable medical devices, the market and manufacturing demand for autoinjector devices are increasing at a staggering rate. Although autoinjectors can offset healthcare treatment costs through self-administered medication, they are expensive for consumers. This paper describes the design and manufacture of a spring-driven and 3-D printed autoinjector using open-source hardware. By making it an open-source resource for everyone, the barrier of advanced research in design and production can be lifted, thus making it easily manufacturable and cost-effective. …

Morphology Of The Acromion And Scapular Spine With Special Interest In The Strength & Failure Prediction After Reverse Total Shoulder Replacement, Andrei M. Matusa, Cole Fleet, George S. Athwal, James A. Johnson

Undergraduate Student Research Internships Conference

Scapular spine fractures following a reverse arthroplasty are a significant clinical concern. This ongoing study looks at the morphology of the acromion and scapular spine with an interest in the strength and failure prediction of the bone. Digital 3D models of the scapular spine were created from cadaver CTs, then bone density and distribution data was obtained. It was found that the cortical bone was most dense just medial of the lateral angle. The cross-sectional area here was also the largest and decreased medially. This has important implications for implant fixation hardware as cortical bone --compared to cancellous bone-- is …

Producing And Measuring Oscillatory Shear In A Novel Microfluidic Chip, Sanaz Lordfard, Daniel Lorusso, Tamie L. Poepping, Hristo N Nikolov, Kayla Soon, Stephen Sims, Jeffrey Dixon, David Holdsworth

Undergraduate Student Research Internships Conference

Purpose: To demonstrate the effectiveness of a novel microfluidic device mimicking oscillatory blood flow, allowing cell biologists to examine how endothelial cells respond to a range of oscillatory shear stress levels.

Methods: The microfluidic chip consists of a circular-shaped reservoir, leading to a rectangular channel that is examined under a microscope. The plunger is connected to a speaker system and oscilloscope, allowing the plunger to apply a range of frequencies (5-60Hz) and voltages (5-10 V, leading to a variety in oscillation amplitudes) to the reservoir region. 1.1 um fluorescent particles diluted in distilled water were used for tracking. Processing was …
