The World Health Organization estimates that over 30 million people require some sort of prosthetic technology. However, traditional prosthetic fitting practices take a lot of time and cost a lot of money, making them inaccessible to millions of people around the world. StandUP Worldwide is an interdisciplinary project team devoted to creating low-cost prosthetic technologies for use around the world, especially in resource poor areas. They are currently developing a low cost, below-the-knee prosthetic kit that can be easily deployed in a resource-poor area. The following presents their solution for a below-the-knee prosthetic socket, foot, and leg.

Ultra-High Field Strength Mr Image-Guided Robotic Needle Delivery Device For In-Bore Small Animal Interventions, Matthew J. Gravett

Electronic Thesis and Dissertation Repository

Current methods of accurate soft tissue injections in small animals are prone to many sources of error. Although efforts have been made to improve the accuracy of needle deliveries, none of the efforts have provided accurate soft tissue references. An MR image-guided robot was designed to function inside the bore of a 9.4T MR scanner to accurately deliver needles to locations within the mouse brain. The robot was designed to have no noticeable negative effects on the image quality and was localized in the MR images through the use of an MR image visible fiducial. The robot was mechanically ...


Diffusion Modeling And Device Development For Peritoneal Membrane Oxygenation, Liana Hatoum 2016 University of Nebraska - Lincoln

Diffusion Modeling And Device Development For Peritoneal Membrane Oxygenation, Liana Hatoum

Mechanical (and Materials) Engineering -- Dissertations, Theses, and Student Research

Acute respiratory distress syndrome (ARDS) is a pulmonary disease that causes hypoxemia and respiratory failure. The mortality rate for ARDS ranges between 27% and 45%. Current treatments including mechanical ventilation and extracorporeal membrane oxygenation (ECMO) are often associated with high risk complications including barotrauma, infection, thrombosis, and hemorrhage. Alternative pulmonary support techniques are needed to improve the survival rate of patients suffering from ARDS. Previous studies introducing pure O2 gas, perfluorocarbons and red blood cells into the intraperitoneal (IP) cavity have reported no effect or only a mild increase in oxygenation. Here we report peritoneal membrane oxygenation (PMO) using ...


Intravital Microscopy Of Tumor Oxygenation And Glycolytic Demand, Jesse D. Ivers 2016 University of Arkansas, Fayetteville

Intravital Microscopy Of Tumor Oxygenation And Glycolytic Demand, Jesse D. Ivers

Biomedical Engineering Undergraduate Honors Theses

There is growing concern about the over treatment of cancer because treatments are based primarily on tumor anatomy. In this study, we aim to begin the process of addressing that issue by developing an intravital technique for optically analyzing tumor biology. Two traits were identified as having significant importance in the aggression of a tumor, vascular oxygenation (SO2) and glycolytic demand. Dorsal skin flap window chambers were implanted and 4T1 and 67NR cancer cells were injected to provide a tumor model for the development of this intravital quantification technique. This study provides a detailed protocol from instrumentation setup to surgical ...


Design Of A 3d-Printed Device For Diffuse Reflectance Spectroscopy Calibration As A Step Towards Clinical Translation, Nontapoth Vongkittiargorn 2016 University of Arkansas, Fayetteville

Design Of A 3d-Printed Device For Diffuse Reflectance Spectroscopy Calibration As A Step Towards Clinical Translation, Nontapoth Vongkittiargorn

Biomedical Engineering Undergraduate Honors Theses

The diffusive reflectance and spectroscopic microendoscopy (DRSME) is a multimodal imaging system that harnesses its usefulness from different light sources. One of the modalities, diffuse reflectance spectroscopy (DRS), has been used in our lab to investigate optical properties of epithelial tissues using a broadband white light as the main source. Calibration of DRS is required as it can obtain the maximum intensity and convert it to absolute reflectance. Current manual-adjusted calibration can be lengthy and often lead to inconsistent results. Therefore, a new method of calibration is introduced where additive manufacturing (or 3D printing) technology is fully utilized.

The instrumentation ...


Design Of Exercise Equipment For Wheelchair Users: A Case Study In Accessibility Standards, Kate Craddock Rescsanszky 2016 University of Connecticut

Design Of Exercise Equipment For Wheelchair Users: A Case Study In Accessibility Standards, Kate Craddock Rescsanszky

Honors Scholar Theses

Engineers must consider a number of aspects of every project they work on. Accessibility is one aspect that presents a unique challenge. Rather than being based on absolute material parameters, accessibility is based on how people interact with technology and their built environment. Since 1990, the Americans with Disabilities Act has been the predominant standard in accessibility because of its wide reach and legal mandate. In addition to the ADA, the ASTM and the Institute for Universal Design offer helpful guidelines for designing for accessibility. However, in addition to standards, guidelines, and recommendations, it is important to consult the intended ...

This allows a person to easily monitor their insulin levels without manually inputting glucose levels into the application. The glucose meter used was a ForaCare Test N’ Go system. To aid in the Bluetooth process, we were granted open access to the glucose meter from Fora Care. The process involved using the programming language of Java in the Android software ...


Design Of Medical Devices For Diagnostics In The Gastrointestinal System, Charles R. Welch 2016 University of Nebraska-Lincoln

Design Of Medical Devices For Diagnostics In The Gastrointestinal System, Charles R. Welch

Mechanical (and Materials) Engineering -- Dissertations, Theses, and Student Research

This thesis presents the design, controls, and testing of two systems: a novel colonoscope locomotion design for diagnostics, and a biosensor capsule that implants a sensor in the small intestine. Each system requires special design considerations for use in the gastrointestinal system.

Colonoscopy procedures are recommended as a screening for colon cancer and related conditions after the age of 50. The need for an improved colonoscope that reduces the colonoscopy time and patient discomfort is apparent. The semi-autonomous device presented here could likely reduce the colonoscopy procedure time by allowing the physician to focus more on the diagnosis and less ...


A Novel Minimally Invasive Tumour Localization Device, Doran Avivi 2016 The University of Western Ontario

A Novel Minimally Invasive Tumour Localization Device, Doran Avivi

Electronic Thesis and Dissertation Repository

Lung cancer is one of the leading causes of death, by cancer. The usual treatment is surgical resection of tumours. However, patients who are weak or have poor pulmonary function are deemed unfit for surgery. For these patients, a minimally-invasive approach is desired. A major problem associated with minimally-invasive approaches is tumour localization in real time and accurate measurement of tool--tissue forces.

This thesis describes the design, analysis, manufacturing and validation of a minimally-invasive instrument for tumour localization, named Palpatron. The instrument has an end effector that is able to support two previously designed jaws, one containing an ultrasound sensor ...


Under The Needle: Ergonomic Issues With Lethal Injection Protocols, Gabriella Hancock 2016 University of Central Florida

Under The Needle: Ergonomic Issues With Lethal Injection Protocols, Gabriella Hancock

Human Factors and Applied Psychology Student Conference

The institution of capital punishment represents one of the most contentious issues affecting societies today; and while the practice is only implemented in 58 countries, the controversy affects the world at large as over 60% of the human population lives in nations that condone the death penalty (Hali, 2015). In the United States, people who support capital punishment believe the practice to be an effective crime deterrent for potential criminals and therefore a prospective protective measure for law abiding citizens. Moreover, advocates defend their position by forwarding the argument that executions are ‘humane’; that use of lethal injection ensures that ...

Circle Of Willis Model For Transcranial Doppler Ultrasound Training, Conner J. Beyersdorf, Ben Hage, Greg Bashford

UCARE Research Products

Transcranial Doppler (TCD) ultrasound is a technique involving the use of high frequency transmitters to measure intracranial blood flow. The brain is supplied by blood in an arterial anastomosis called the Circle of Willis. Using TCD ultrasound on the circle is difficult and requires practice and teaching. A functional model of the Circle of Willis could prove to be a valuable teaching tool. Through the use of AutoCAD and 3D printing software, an anatomically accurate model was created and set in gelatin phantom inside of a plastic skull. Milk was pumped through the model with a peristaltic pump to simulate ...

Detecting Heart Failure Decompensation By Measuring Transthoracic Bioimpedance In The Outpatient Setting: Rationale And Design Of The Sentinel-Hf Study, Silviu Dovancescu, Jane Saczynski, Chad Darling, Jarno Riistema, Fatima Kuniyoshi, Theo Meyer, Robert Goldberg, David Mcmanus

David D. McManus

BACKGROUND: Recurrent hospital admissions are common among patients admitted for acute decompensated heart failure (ADHF), but identification of patients at risk for rehospitalization remains challenging. Contemporary heart failure (HF) management programs have shown modest ability to reduce readmissions, partly because they monitor signs or symptoms of HF worsening that appear late during decompensation. Detecting early stages of HF decompensation might allow for immediate application of effective HF therapies, thereby potentially reducing HF readmissions. One of the earliest indicators of HF decompensation is intrathoracic fluid accumulation, which can be assessed using transthoracic bioimpedance.

OBJECTIVE: The SENTINEL-HF study is a prospective observational ...


Design And Validation Of A Fall Detection Application For Ios, Connor Lewis Mosley 2016 California Polytechnic State University - San Luis Obispo

Design And Validation Of A Fall Detection Application For Ios, Connor Lewis Mosley

Master's Theses and Project Reports

Despite significant preventative efforts, falls continue to be a major source of morbidity and mortality among the elderly. Additionally, the fear of falling can be a major obstacle to independent living for otherwise self-sufficient individuals. This fear is significantly heightened in individuals who have sustained a fall and often results in self-imposed restrictions on mobility and exercise, causing weakening in these individuals and further exacerbating the danger. Much time has been spent developing alert systems in an attempt to mitigate these problems. Unfortunately these systems typically involve dedicated monitoring centers and therefore often come with substantial upfront and recurring costs ...
