Nanocellulose Based Foams For Low-Cost Disposable Medical Applications, Dominic Kugell Aug 2023

Nanocellulose Based Foams For Low-Cost Disposable Medical Applications, Dominic Kugell

Electronic Theses and Dissertations

Polyurethane foams have been a staple material for their use in medical positioners, such as post-surgery elevation pillows as well as specific tailored positioners for their use during surgery. Polyurethane foams are preferred because of their lower cost compared to other petroleum derived foams, their versatility, and suitable mechanical properties. However, the environmental impact, including both cost and perception, of these foams is immense. Therefore, alternatives are being explored with biopolymers emerging as a promising class of materials. Cellulose is one such polymer that has recently demonstrated desirable properties. In this study, cellulose nanofibrils (CNF), a household foaming agent, and …


Calibrated Tensioner For Total Knee Arthroplasty Gap Balancer, Lauren Henigman, Jaypreet Dhanota, Corey Catuara Jun 2021

Calibrated Tensioner For Total Knee Arthroplasty Gap Balancer, Lauren Henigman, Jaypreet Dhanota, Corey Catuara

Biomedical Engineering

The purpose of this project was to design a device that interfaces with the previously created gap balancer to simultaneously measure the gap between the femur and tibia and measure the tension in the ligaments of the knee. First, we met with Dr. Delagrammaticas to outline the key customer requirements: we wanted the device to be precise, sterilizable, reliable, and compatible with the gap balancer. Based on the customer requirements, we outlined the specifications that would drive our design and testing, which included precision, ease of use, size, and material properties. The design process began by using a morphology to …

Enhanced Blood Pressure Acquisition, Alison Targosky, Megan Laws, Alexandria Stephens, Jillian Savage Jan 2020

Enhanced Blood Pressure Acquisition, Alison Targosky, Megan Laws, Alexandria Stephens, Jillian Savage

Williams Honors College, Honors Research Projects

Blood pressure is considered a primary vital sign that is regularly monitored in a healthcare setting. Current blood pressure measurement equipment lacks reproducible measurements which leads to questionable accuracy. Therefore, there is a need for an accurate and reproducible blood pressure measurement device that can take remote measurements. This project will be designed in The University of Akron's biomedical engineering capstone course. The goal of this senior design project is to design and fabricate a blood pressure measuring device that meets the customer requirements and engineering requirements identified by the team.


Design And Development Of A Wireless Eeg System Integrated Into A Football Helmet, Akshay V. Dunakhe Mar 2019

Design And Development Of A Wireless Eeg System Integrated Into A Football Helmet, Akshay V. Dunakhe

USF Tampa Graduate Theses and Dissertations

In the United States, approximately 2.8 million Traumatic Brain Injuries (TBI) occur annually. Out of these 2.8 million occurrences, 280,000 injuries are caused by sports and recreational activities. The actual number can be significantly higher since mild TBI are often unrecorded. These injuries not only cause physical damage to players, but they are also one of the leading causes of a player’s retirement from a sports career. While working with TBIs, it is vital to detect the concussion at its first occurrence, termed as a “primary concussion.” If the primary concussion goes undetected, the player may continue to play the …


Prevention Of Access Recirculation During Hemodialysis Treatment, Brendan Laing, Emma Merlino, Charles Nelson Mar 2019

Prevention Of Access Recirculation During Hemodialysis Treatment, Brendan Laing, Emma Merlino, Charles Nelson

Honors Theses

Approximately 660,000 Americans are being treated for kidney failure or end stage renal disease annually. Access recirculation can happen to any patient, varying from treatment to treatment, as it is a problem with the current technology of two butterfly needles used during a dialysis procedure and not with the patient. Access Recirculation severely decreases the efficiency of dialysis while having the potential to lead to a variety of complications.There is a clear need for a device that can be implemented during hemodialysis treatments to reduce the percentage of recirculated blood, thusly reducing the occurrence of treatment for an individual and …


Design And Development Of A Multifunctional Surgical Device For Ground And Space-Based Surgical Applications., Brooke Elaine Barrow Apr 2018

Design And Development Of A Multifunctional Surgical Device For Ground And Space-Based Surgical Applications., Brooke Elaine Barrow

Electronic Theses and Dissertations

With the possibility of longer ventures into space, NASA will face many new medical challenges. The ability to surgically treat trauma and other disorders in reduced gravity requires reliable wound access, containment, and visualization. In collaboration with Carnegie Mellon University, the University of Louisville is currently developing the AISS (Aqueous Immersion Surgical System) to increase efficiency and control of the operative field in space-based surgeries. Reliable wound access and containment is achieved by placing a transparent wound-isolation dome securely over the wound-site and pressurizing it with a saline solution. Leak-free trocars provide access ports for various surgical instruments. This system …

A Magnetic Actuated Fully Insertable Robotic Camera System For Single Incision Laparoscopic Surgery, Xiaolong Liu Aug 2015

A Magnetic Actuated Fully Insertable Robotic Camera System For Single Incision Laparoscopic Surgery, Xiaolong Liu

Doctoral Dissertations

Minimally Invasive Surgery (MIS) is a common surgical procedure which makes tiny incisions in the patients anatomy, inserting surgical instruments and using laparoscopic cameras to guide the procedure. Compared with traditional open surgery, MIS allows surgeons to perform complex surgeries with reduced trauma to the muscles and soft tissues, less intraoperative hemorrhaging and postoperative pain, and faster recovery time. Surgeons rely heavily on laparoscopic cameras for hand-eye coordination and control during a procedure. However, the use of a standard laparoscopic camera, achieved by pushing long sticks into a dedicated small opening, involves multiple incisions for the surgical instruments. Recently, single …


An Assessment Of Novel Biodegradable Magnesium Alloys For Endovascular Biomaterial Applications, Dharam Persaud-Sharma Jun 2013

An Assessment Of Novel Biodegradable Magnesium Alloys For Endovascular Biomaterial Applications, Dharam Persaud-Sharma

FIU Electronic Theses and Dissertations

Magnesium alloys have been widely explored as potential biomaterials, but several limitations to using these materials have prevented their widespread use, such as uncontrollable degradation kinetics which alter their mechanical properties. In an attempt to further the applicability of magnesium and its alloys for biomedical purposes, two novel magnesium alloys Mg-Zn-Cu and Mg-Zn-Se were developed with the expectation of improving upon the unfavorable qualities shown by similar magnesium based materials that have previously been explored. The overall performance of these novel magnesium alloys has been assessesed in three distinct phases of research: 1) analysing the mechanical properties of the as-cast …

St. Jude Medical: An Object-Oriented Software Architecture For Embedded And Real-Time Medical Devices, Atila Amiri

Master's Theses

Medical devices used for surgical or therapeutic purposes require a high degree of safety and effectiveness. Software is critical component of many such medical devices. The software architecture of a system defines organizational structure and the runtime characteristic of the application used to control the operation of the system and provides a set of frameworks that are used to develop that. As such, the design of software architecture is a critical element in achieving the intended functionality, performance, and safety requirements of a medical device. This architecture uses object-oriented design techniques, which model the underlying system as a set of …
