Rod Bend Approximator For Minimally Invasive Spinal Surgery, Amanda Hansell, Anise Ghandchi, Shervin Moghimi

Biomedical Engineering

This Final Report will go over the project deliverables and future steps in the making of a rod bending approximator tool by the Cal Poly Senior Design team for the client SeaSpine. The latest designs and research done regarding minimally invasive surgery (MIS) is covered including the impediments with the current methods. SeaSpine presented the need to our team for an approximating tool within the MIS procedure. Our team began project planning through task generation and schedule development. Once the product definition was fully understood, competition was evaluated and engineering specifications were created for the project. A conceptual design was …

3-In-1 Medical Lancet, Jonathan J. Panella, Gage Vogtlin, Marissa Koski, Benjamin Neyland

Mechanical Engineering

First responders need a quick, sterile, and convenient way to sample blood for glucose testing because glucose levels are a vital metric in assessing time-critical emergency situations. The blood sampling process consists of pre-sterilizing the sample site on the skin with an alcohol pad, pricking the skin with a lancet, and lastly, after sampling, putting a bandage over the prick site. The scope of this project is to design a device which integrates and streamlines the use of the three sub-processes (sterilization, lancing, and bandaging) while upholding the necessary requirements of a single-use medical device and considering other factors which …

Laser Micropatterning Effects On Corrosion Resistance Of Pure Magnesium Surfaces, Yahya Efe Yayoglu

USF Tampa Graduate Theses and Dissertations

Magnesium and its alloys are good candidates to manufacture medical implants. They have excellent biocompatibility and because they biodegrade secondary surgical operation to remove the implant could be eliminated. However, in aqueous environments, magnesium alloys rapidly corrode, resulting in premature degradation of the implant along with biologically intolerable hydrogen gas generation. In literature, there are multiple studies focused on creating water repelling hydrophobic magnesium surfaces in order to decrease corrosion rates. Hydrophobic properties can be achieved by creation of a roughness profile on an initially smooth surface combined with a treatment that reduces the free surface energy. In theory, hydrophobic …

Urinalysis Screening For Rural Communities, Dana Bren-Cardali, Lilian Dao, Jeffrey Destruel, Ryan Fernandez

Interdisciplinary Design Senior Theses

Access to medical care and health screenings is a necessity for patients around the globe, but it can be difficult to provide this without screenings becoming costly or convoluted. In rural and underdeveloped areas, patients are often disadvantaged when it comes to finding reliable and affordable healthcare. The isolation provided by their location and the rising costs of physicians makes it impossible for most impoverished communities to attain personalized care. Because of this, treatable diseases often go unaddressed, allowing diseases to progress to a critical condition. Mortality rates have shown to be higher in communities located in rural areas and …

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 …

Corrosion Characteristics Of Magnesium Under Varying Surface Roughness Conditions, Yahya Efe Yayoglu

USF Tampa Graduate Theses and Dissertations

The biggest challenge with magnesium alloy biodegradable implants is the rapid corrosion at the earlier stages of the healing process after implantation. In this research, the impact of surface roughness generated by different means on the corrosion rate of AZ31 magnesium alloy in a simulated biologic environment is investigated. In order to perform accurate experimentation, an in vitro setup is assembled that simulates the human body environment accurately has been prepared using Schinhammer’s in vitro immersion testing setup and Kokubo’s Simulated Body Fluid (SBF). For the immersion test of Mg in SBF, several surface texture groups of Mg have been …

Mums: Mobile Urinalysis For Maternal Screening, Blair Koeneman, Amy Miller, Joe Neumeyer, Jake Prince

Interdisciplinary Design Senior Theses

Pregnant women in low-income communities often lack access to the necessary healthcare for successful births. This is frequently due to the high costs of medical care, the remote location of patients, and the infrequency of primary care medical visits. To address this inequity, we have created a mobile application and imaging unit that allows for the low-cost implementation of urinalysis testing, which will aid in the detection of warning signs for prenatal health risks. From a single photo taken with a tablet camera, our application digitizes the results of a standard urinalysis test strip, displays the test results, and tracks …

Improving Pediatric Cardiology Consultation Methods By Introducing Digital Interactive 3-D Heart Models: A Proof Of Concept Study, Adam Verigan

USF Tampa Graduate Theses and Dissertations

The purpose of a pediatric cardiology consultation is to inform, or educate, the patient and family of all aspects surrounding a certain congenital heart defect. Consultation education methods and materials may include verbal descriptions, two-dimensional (2-D) heart diagrams, and take-home pamphlets. Because the human heart is a complex three-dimensional (3-D) object, the problem lies within the clarity to which these methods are performed by the doctors and understood by the patients and families. Therefore, during a consultation the cardiologist must a) possess the ability to describe a defect visually as well as verbally and b) ensure that the patient and …
