The Second Wind, Jacob Heiss, Logan Neidert

Williams Honors College, Honors Research Projects

The Second Wind device is a set of sensors and a data processing unit capable of recording data necessary to conduct a simplified version of a complex cardiopulmonary stress test (CPET). This data includes VO2, VCO2, ventilation, and pulse oximetry data. VO2 and VCO2 are the percent, by volume, of oxygen and carbon dioxide in the patient's breath, spirometry is the measure of air flow, and the pulse oximetry data includes heart rate (HR) and percent oxygen in the blood (SpO2). In addition, the device was designed to be portable, so this test could be run from patients’ homes or …

Quickcough: An Instrumentational Proximal Airway Clearance Technique (Act) For Select Patients With Neuromuscular Disease (Nmd), Sean X. Sullivan, Russell K. Catania, Madison K. Plaster, Sydney E. Kandray, Mariah Costa

Williams Honors College, Honors Research Projects

Patients with neuromuscular disease (NMD) requiring tracheostomy and mechanical ventilation secondary to respiratory failure encounter increased difficulty in removing pulmonary secretions from the airways. To combat issues associated with current treatment modalities for insufficient cough efficacy (cost, poor mobility, discomfort, lack of evidence), we have developed an instrumentational proximal airway clearance technique (ACT) which augments a manual proximal ACT developed by a client with NMD. QuickCough is a 3D-printed PLA attachment to the tracheostomy apparatus which has demonstrated its ability to facilitate pressure changes necessary to increase patient’s peak cough flow (PCF) by providing a stronger exsufflation for the patient. …

Easy Adjustable Protective Helmet, Ryan Balash

Williams Honors College, Honors Research Projects

Akron Children’s Hospital and The University of Akron’s Biomedical Engineering Design Team Engineering Forward have paired together to improve medical adapted helmets for post-operative and disabled patients. An issue is the helmets are only produced in a couple of sizes. Also, it is a tedious process to constantly adjust the pressure on the patient’s cranium within a trial-and-error process. Engineering Forward plans to improve the effectiveness of this helmet by creating an adjustable helmet that can read the pressure on a patient’s head. The caregiver can then make the necessary adjustments to the helmet to accommodate the patient. Documents of …

Williams Honors College, Honors Research Projects

We set out in August 2017 to develop an active noise suppressing device that would be usable both in military and civilian activities. Due to constraints in knowledge and time, we decided our best course of action was to divide the project into two equal projects with the hope to be able to combine them into a single project at the end of the allotted time. This consisted of an active noise suppression device and a passive noise suppression device. The passive device would have no electronic components and the active device would be pure circuitry with no housing. This …

Lighted Ear Curette, Kelsey Ashmore, Kaitlin Klotzle, Crysta Yamamoto, Katrina Elfrink, Cynthia Stoller

Williams Honors College, Honors Research Projects

The ear canal is a sensitive and small part of the human body that is prone to accumulate cerumen or lodge foreign bodies. In order to clean the ear canal or remove foreign bodies, three hands are required: one to brace the patient's head, one to maneuver the curette that is used to clean the ear, and one to hold a light source in order to make the small, dark area visible. Therefore, a design is needed that can allow a doctor to safely clean an ear with an instrument that only requires two hands. Furthermore, the design must have …

Characterization Of Polyurethane For Use As Substrate In Nanofiber Sensor For Biomedical Applications, Megan Theaker

Williams Honors College, Honors Research Projects

The purpose of this project is to begin to determine properties of polymer nanocomposites that make a suitable substrate for nanofiber sensors. In this work, sensitivity of a sodium ion selective sensor constructed with polyurethane was used as a benchmark for comparison with sensors constructed with nylon-6. The sensors were characterized using contact angle and chronoamperometry. Using an ANOVA analysis, the results showed that the multi-walled carbon nanotube type was a significant factor on sensor response both with and without additional functionalization of the polymer by calixarene. The weight percentage of polyurethane in the electrospinning solution was also statistically significant …

A Software Application For Cardiac-Gated Computerized Tomography Scanning, Stephen Caldwell, Trevor Engelsman

Williams Honors College, Honors Research Projects

Computerized tomography (CT) scans are a common clinical imaging procedure used worldwide. Operating in the X-Ray spectrum, these machines rotate scanners around a stationary body in order to compile two-dimensional images into a unified three-dimensional image. With adjustment to scan frequency and intensity, internal features such as muscles, organs, and tendons can easily be viewed. However, the heart has long evaded CT use due to its near-constant motion. Recently, cardiac-gated scans have entered the market as a technique to image the heart at a specific moment in time when it is nearly still - the quiescent period. Occurring during rapid …

Fretting corrosion due to micromotion between the femoral head and neck of hip implants is a growing concern of surgeons and patients. Debris from corrosion can lead to severe adverse effects for patients of total hip arthroplasty and reduce the lifespan of the product. Previous studies conducted by Zimmer Biomet show a connection between higher impaction force and reduced fretting corrosion and debris. This design project explored this issue and developed a training device using a current technology, a dynamic force sensor, and data analysis software for surgeons to obtain muscle memory of a 4kN strike on the head impactor, …

Pediatric Electrical Stimulation For Limb Lengthening: A Non-Invasive Approach, Corey J. Schurko, Sofia Chinchilla, Amanda E. Pinheiro, Jacob A. Brock

Williams Honors College, Honors Research Projects

Leg Length Discrepancy (LLD) is a problematic ailment for children as the differences in limb lengths can lead to scoliosis, hip, knee, and ankle problems, and back pain. If LLD is untreated, the symptoms will worsen as the child matures. Today LLD is corrected by using the Ilizarov Method, which uses pins that are externally attached to the broken bone for extension over time using a fixator or by using internal plates that do not require externalization. In our project we aim to use external electrical stimulation to correct the limb discrepancies. Several companies, such as Zimmer Biomet, have created …
