Enhancement Of The Syncardia Total Artificial Heart For Pediatric Use, Margaret Clark, Madison Marks Jan 2020

Enhancement Of The Syncardia Total Artificial Heart For Pediatric Use, Margaret Clark, Madison Marks

Williams Honors College, Honors Research Projects

Pediatric patients with disorders and diseases of the heart have limited options with regards to implantable devices. Many of these implants are ventricular assist devices, which is not always suitable for a patient. Total artificial hearts (TAHs) have supported many adult patients until transplantation, and we believe that they could do the same for pediatric patients. SynCardia has the only Food and Drug Administration (FDA) approved TAH devices. Since SynCardia is the only company with FDA approved TAHs, we decided to modify the design of the SynCardia TAH for use in pediatric patients without compromising the function of the current …

Integrated Dentistry Face Shield, Noah Glass

Williams Honors College, Honors Research Projects

Currently, the United States and the entire world is experiencing a global pandemic that has drastically changed the way we go about our everyday lives. Dr. Pavlik, a local dentist is one such person who has had to alter his normal dentistry routine to one of extreme caution while working on patients. His day to day job puts him at a high risk of being exposed to Covid-19 by actively working in patients’ mouths at proximity. Dr. Pavlik’s current dentistry equipment is lackluster in its compatibility with his safety equipment. To help minimize exposure to Covid-19 for Dr. Pavlik and …


Pediatric Blood Calculator, Richard Desatnik Jan 2020

Pediatric Blood Calculator, Richard Desatnik

Williams Honors College, Honors Research Projects

This paper outlines an expert system based solution for calculating the optimal amount of blood draw from infants to carry out critical tests requested by the attending clinicians. The solution is a hand-held device with a user-friendly interface that allows a meaningful two-way conversation between the clinician and the pathology office. Based on the tests being requested, the calculator determines the minimum amount of blood required in the different vials based on a smart expert system. This removes the uncertainty that is prevalent today in the amount of blood required to do all the tests, since in some cases there …


Medical Device For Loading Of Knee At Differing Angles, Alex Dragota Jan 2020

Medical Device For Loading Of Knee At Differing Angles, Alex Dragota

Williams Honors College, Honors Research Projects

Abstract

This was a design report for a device that would be used in patellar instability research. The device would be used inside an MRI machine and allow the patient to adjust the angle of their knee to the desired position.

Methods: Solidworks was used in the design process to model and to simulate the strength of the components used. The Solidworks simulation software allowed for a better understanding of the strength of individual components and the strength of the full device. Complexity of operating the device while inside an MRI machine were taken into account by using animations of …


The Tera Multi Terrain Mobility Aid Chassis, Colton Kemp, Daniel Nicoll, Ibrahim Suleiman, Mohammad Alyami Jan 2020

The Tera Multi Terrain Mobility Aid Chassis, Colton Kemp, Daniel Nicoll, Ibrahim Suleiman, Mohammad Alyami

Williams Honors College, Honors Research Projects

The natural environment poses a significant number of obstacles and dynamic settings that makes mobility difficult for those with physical and mobility impairments. To approach this problem, a suspension was designed using inspiration from the early Mars rovers developed by NASA for traversing the varied Martian landscape. The course of the project followed the direction of a start-up through problem identification, early design generation and review, and final design production. The project outcome, through client request and proven market research, aimed to produce a multi-terrain wheelchair. The final product is a kinematic body with mobile front “legs” and a rotational …


Exoskeleton Leg Brace, Aaron Indermuhle, Magomed Kasumov, Cevat Bagcioglu, Lucas Battaglia Jan 2019

Exoskeleton Leg Brace, Aaron Indermuhle, Magomed Kasumov, Cevat Bagcioglu, Lucas Battaglia

Williams Honors College, Honors Research Projects

This report details the design process of a lower limb exoskeleton leg brace for elderly people with walking disabilities or others with disabilities that limit mobility. While there are other similar products on the market, the general design can be improved and these improvements have been implemented into the design presented within. Among these improvements are progress in efficiency, weight, user comfort, and cost. The results of the study are the design of a novel leg brace that improves on existing designs in each of these areas.

Our design solution incorporates the use of a single leg brace with no …


Design And Mechanical Characterization Of 3d Printed Gradient Porosity Poly(Propylene Fumarate) Scaffolds, Andrea Felicelli Jan 2019

Design And Mechanical Characterization Of 3d Printed Gradient Porosity Poly(Propylene Fumarate) Scaffolds, Andrea Felicelli

Worldwide incidence of bone disorders and conditions, an already prevalent problem, is expected to double by 2020 from the rate in 2013 due to factors such as higher life expectancies and lower levels of physical activity. Every year in the United States, over half a million patients receive bone defect repairs, with costs greater than $2.5 billion. Current repairs are typically done with bone grafts, which are often costly and can result in added complications in the donor surgical site. Tissue engineering, a growing field that seeks to assist and enhance tissue defect repairs through the use of synthetic materials, …


Lighted Ear Curette, Kaitlin Klotzle, Kelsey Ashmore, Crysta Yamamoto, Katrina Elfrink, Cynthia Stoller Jan 2017

Lighted Ear Curette, Kaitlin Klotzle, Kelsey Ashmore, 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 …

The University of Akron’s Air Force Research Laboratory’s Design Challenge Team has engineered a Heat Stress Prevention Kit that includes a facial mask in which the soldier will cool down from the inside out by breathing in the cool air circulating throughout the mask. This cool air is produced from a thermoelectric chip, which has a specific temperature difference on either side, one hot and one cold. Each of the sides is isolated from one another and with the combination of heat sinks, fans, and the simple process of breathing, a system is created by inhaling cool air. The entire …


Prosthetic Thermal Management Device, Garrett Dowd Jan 2015

Prosthetic Thermal Management Device, Garrett Dowd

Williams Honors College, Honors Research Projects

High temperatures in lower-limb prosthetics can lead to poor user skin conditions and mechanical slippage between the user’s limb and the prosthetic. This report presents an air-cooling device for a lower-limb prosthesis. This device’s purpose is to maintain a constant skin-prosthesis interface temperature. A compact heat sink and small fan were used to transfer the bio-heat to the ambient surroundings. By changing the power of the fan, the thermal resistance of the whole system can be adjusted to match various thermal loads and environmental temperatures. Heat pads were used to mimic the heat generation of a residual limb, and cooling …
