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 And Strain In The Subchondral Trabeculae Of Osteoarthritic Humeral Heads, Anna Yang

This project compares the strains and morphological parameters of subchondral bone in osteoarthritic and non-pathogenic cadaveric humeral heads.

Normative Joint Angles And Compensation During Fit-Hansa Test, Jennifer J. Villeneuve

Undergraduate Student Research Internships Conference

Imagine a world where no injuries occurred, muscular compensation was able to be detected early on and imbalances resolved before any risks appear. Muscular compensation can cause injuries, especially with repetitive motion or through activities of daily living. The study I conducted focuses on the compensation methods of shoulder abduction and trunk lean during the FIT-HaNSA series. Determining the normative ranges of motion can increase early detection of fatigue for all individuals. This can help make repetitive jobs such as working in a factory much safer for all employees, as they can switch tasks as soon as fatigue is identified. …

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 …

Tca Fabrication Devices, Brendan R. Difabio

Undergraduate Student Research Internships Conference

Twisted coil actuators are a recent technology that has different properties from popular actuators used today. Being so new, there is still much to learn about these actuators. This project aims to create devices that can be used to make the fabrication process simple and repeatable.

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 …

Development Of A Low-Cost Algometer, Thomas D. Naish, Ana Luisa Trejos, Dave M. Walton

Undergraduate Student Research Internships Conference

Many people suffer from chronic pain, the reasons for which are not always well understood. Algometers are instruments that can help clinicians understand the nature of pain by determining the force at which pain becomes noticeable or unbearable. Algometers can also be used to determine the effects that external influences can have on pain tolerance in healthy people.

The goal of this project was to develop an algometer that can measure the normal range of pain thresholds and tolerances of most patients, which ranges up to 35 lbs. Also, the result needed to be accurate to about 1% and made …
