Biomedical Engineering Design II

Atlus, An Alternative Approach to Charcot Foot Limb Salvage | Limb salvage surgery is the first-in-line treatment to restore function to a
traumatized limb with extreme bony defects. Tibiotalocalcaneal (TTC)
Arthrodesis is a limb salvage procedure performed on patients with
Charcot Arthroneuropathy or Charcot foot, a chronic complication of Type
II Diabetes. Eventually, severe bony defects form around the ankle and
may require surgery to remove portions of diseased bone. To fill the bony
void, current technologies involve the use of femoral head allografts and
patient- specific implants. However, these methods are costly, lack
reproducibility, and are difficult to design. The Atlus allows for
osseointegration and ease of implantation. With the novel device,
surgeons may leverage an off-the-shelf product to reduce the reliance on
expensive custom implants.

Ultrasonic Ozone Sterilization Unit (UO3SU) | As of 2016, 20-30% of US medical practices reuse at least 1 type of single-use device, for hospitals it may be B.P. Handle and for dentistries it may be a dental mirror or an explorer, but of these devices/tools that get reused, only 2-3% of them are safely re-sterilized properly for reuse. With some of these single-use items, because the time and effort needed to clean these devices outweigh the benefit of using them again, most hospitals turn to disposing the medical tools. Therefore, there is a need for a sterilization unit that can effectively clean medical equipment with speed and efficiency. The device our team has created to assist in increasing the percentage of reusable single-use items in the dental field is known as the Ultrasonic Ozone Sterilization Unit or UO3SU. The UO3SU device is configured with aqueous ozone (O3), formed via electrolysis, in combination with ultrasonic vibrations to rid dental instrument surfaces of any contaminants (living and non-living) that may reside on the surface. Using these two very effective methods, our device is expected to be able to fully sterilize any instrument with a higher success rate and a faster turnaround time than our top competitor, the Autoclave. With the Ultrasonic Ozone Sterilization Unit, hospitals and clinics could save billions of dollars in the medical equipment market, which is currently worth approximately 488.98 billion USD.

Fluid Recirculation System for Intravascular Lithotripsy Recirculation | Calcium Buildup deposits in heart arteries occur in over 90% of men and 67% of women older than 70 years. It is most alternately characterized in people with higher body mass index, abnormal glucose or lipid level, and kidney disease. To combat coronary calcification, intravascular lithotripsy catheterization devices are a new technology which enables physicians to break up calcium deposits in arteries using sonic pressure waves however these current devices use manual fluid insertion for the catheter. The focus of this project is to implement a fluid recirculation system into existing catheterization devices specifically to remove bubbles from the fluid.

Prothrombin Time Sensor | There is a need for a at home prothrombin time detector to provide quick and accurate results at the comfort of the patient's home. Only a few coagulometers are currently available on the market, which forces patients to travel frequently and at great expense to the hospital in order to get crucial diagnostic information. Due to the limited number of at home coagulometers’ and inadequate marketing, many patients are unaware of their options. Instead of lasers, most coagulometers use reagents, which have a higher device failure rate. The market for anticoagulation devices is growing; it was predicted that the value of coagulation devices would be 27 billion in 2017 and increase to 43 billion by 2025. Many patients would benefit from at home testing, highlighting the need for a device that can test for blood clotting time, providing patients with critical diagnostic information that will allow them to make informed decisions about their treatment plans with their primary healthcare provider. As a result, we have developed the at home prothrombin time detector using a laser that patients can carry and use where ever they may please.

Laser Intravascular Lithotripsy (IVL) Balloon Catheter | Coronary artery disease (CAD) is the one of the leading causes of death in the world, affecting 3 million people in the US and 20.1 million people globally. CAD is characterized as the accumulation of plaque composed of lipids and calcium that penetrate the endothelial layer of cells lining the underside of blood vessels and arteries. The accumulation of plaque restricts blood flow by narrowing and decreasing the compliance of blood vessels. In chronic cases, heart attacks and even death can occur.
Balloon angioplasty has traditionally been used in treatment of arterial calcification. While it has been effective in some cases, many shortcomings remain. Today there remain no balloon catheters which can address coronary artery calcification in the smallest coronary arteries, which can be as small as 1.0 mm in diameter. As it stands, standard balloon angioplasty is also unable to successfully break down calcification in chronic cases.
This has led to angioplasty modifications in larger arteries (e.g. peripheral) which now predominantly utilize intravascular lithotripsy to more effectively break down calcification and create better vessel compliance. Intravascular lithotripsy uses a standard balloon catheter to generate and propagate shockwaves which break down and fracture the plaque. Peripheral artery approaches consist of electrode-based lithotripsy as seen in the main competitor Shockwave IVL. While this technology is effective, it is unable to be scaled down to the size of the coronary arteries given its use of electrode-based technology.
Referring back to traditional laser lithotripsy approaches in the kidneys, this design intends to adapt lithotripsy techniques through the use of optical laser fibers. Such a technique allows for the construction of a laser lithotripsy balloon catheter which has the ability to treat coronary artery calcification in the smallest arteries.

S.I.Jig | The Sacroiliac joint is an immobile joint connecting the spine to the pelvis. When this joint moves too much, it causes severe pain. One treatment is posterior SIJ fusion, which involves surgically embedding an implant into the joint through the back of the patient and fussing the bones. This method is minimally invasive but less effective due to the joint’s narrow-angle of entry and the ineffectiveness of current implants. The SI-Jig incorporates a surgical guide to aid surgeons in entering the joint and a cannulated implant designed to immobilize the joint and promote bone fusion

Aqueous ozone acute wound care device | Acute wounds account for approximately 50 million hospital visits and ambulatory services every year. Current debridement options during emergency situations include irrigation of 2 L of saline or water, however, they do not kill bacteria or viruses. The patients risk developing an infection which can lead to higher expenses. Using antimicrobials and antiseptics can cause adverse reactions to the skin and healthy cells. There is a need to develop a device to decrease infection rates by creating an oxygen-rich environment to increase healing for acute wounds during emergency situations. Previous research demonstrates aqueous ozone is an antibacterial, anti-inflammatory, and vasoconstricting agent. We propose to create a quick and effective debridement device using aqueous ozone by electrolytic conversion.

Portable Oral Water Flosser | Oral sanitization before surgery reduces the possibility of open wound and bacterial infections. There is currently no chemical mouthwash commercially available that is safe and natural enough for patient-use as they can cause further problems including dehydration and gum inflammation. Prior to performing dental work, ozone water can be used as a pre-rinse to clean the surgical area without harsh chemicals. Aqueous ozone is a natural, practical and affordable treatment that can promote wound healing and guard against oral disease. Presented in this project is a design that incorporates aqueous ozone into dental appliances.

Fluidic Mixing Bioprinting System & Incubation Enclosure | Over 160,000 skin grafts are performed in U.S. hospitals annually, with 1 in 3 burn hospitalizations requiring a skin graft. Current skin graft methods involve using skin from a donor site on the patient, skin from another person/animal, or a synthetic substitute. Recent advances in bioprinting have shown a promising future where bioprinters can be used to create patient-specific skin grafts, other tissues, and even artificial organs. However, current bioprinters are incapable of printing high-quality viable tissue samples due to improper cell distribution and a lack of an enclosure system to protect the cells during printing. Our proposed bioprinting system will include a novel mixing system to improve cell uniformity and will be housed in an enclosure capable of maintaining the optimal conditions for the printed cells.

Quantifying the selective advantage of colorectal cancer driver genes in a whole-genome sequencing cohort of 1015 patients| Colorectal cancer (CRC) is a leading cause of death in the US, with 52,000 deaths in 2022. In a study by Zhao et al., 46 CRC-associated genes were identified in a cohort of 1015 patients using whole exome sequencing. However, their method based on gene mutation frequency alone does not determine its contribution to cancer. To address this, we used computational and evolutionary techniques to calculate effect size and quantify the significance of the identified genes. This allowed us to prioritize high-effect genes and variants for drug design, demonstrating the practical utility of quantifying selection intensities in cancer research.

Robotic Probe Holder for Ultrasound Imaging | Ultrasound imaging is currently used in combat casualty care to triage a patient’s injuries and prioritize evacuations. Personnel are oftentimes inexperienced with this technique, which is why it is necessary to simplify ultrasound imaging acquisition.
This proposed project is the development of a robotic probe holder for use as an attachment to a robotic arm system to perform automatic ultrasound imaging. The main focus of this device is to adjust to multiple probe sizes and shapes, to deliver gel to the tissue surface at each point of the exam, and to ensure adequate force is being applied to the patient.

Adhesive Securement Device for a Crichothyrotomy | A cricothyrotomy is an emergency procedure that delivers oxygen to a patient's blocked airway. This is done by inserting a tube down the cricothyroid membrane. Currently, in order to secure the tube, methods of suturing, trach ties, or velcro straps are used so no internal bleeding happens. The shortcomings of these methods are that not all paramedics can suture, and trach ties and velcro straps can be complex during an emergency with blood and hair involved. Our goal is to improve upon these devices by using a skin adhesive. Our design must stay secured to the patient, and have quick and easy application.

Stabilizing Procidentia | 11-20% of women will undergo a uterine prolapse repair procedure in their lifetime. Current devices such as mesh implants have been recalled from the market and invasive procedures such as hysterectomies may lead to further complications, suggesting that there is a need for a medical device to better repair uterine prolapse in patients. Our mission as a team is to contribute to the well-being of women through innovative medical devices and shine a light on areas of women’s health that are neglected. Through the use of a uterine pessary ring, our device aims to provide a non-surgical remedy to all stages of uterine prolapse. By combining a drainage mesh with suction cube supports, our ring is capable of being used for multiple weeks without removal and supporting the entire weight of the uterus. To ensure the safety and compatibility of our device, we have established and completed numerous tests including biocompatibility, pH degradation, cytotoxicity, and sterilization ability.

Aqueous Ozone Chronic Wound Therapy Device | Chronic wound care is a complex process greatly affected by accompanying diseases which compromise the wound healing process. Current wound care treatments employ the use of antibiotics, which over time have become less efficient, and medical device technologies often require the patient’s presence in a hospital or wound care clinic as their large sizes only allow for use in a clinical setting. To address this, our team has designed a portable, wearable device for post-op or at-home wound care treatment incorporating aqueous ozone, a highly reactive oxidant that directly attacks the surface layer of microorganisms and destroys their cell walls.

Tripolar Left Ventricular Assist Device for Volumetric Measurements | The use of percutaneous left ventricular assist devices (pLVADs) is increasing in the management of heart failure or cardiogenic shock patients. However, ongoing research is being conducted to determine the optimal utilization and device-related outcomes. This project aims to develop a safe and biocompatible implantable device that utilizes three electrodes to measure cardiac output (CO) readings in the heart, assessing left ventricular (LV) recovery. The device will be capable of multiple deployments and measurements for up to one year, providing an upgrade to the current catheter-based pLVAD design.

The purpose of this project is to design a safe and biocompatible device that is an improvement of the current commercially available catheter-based miniaturized ventricular assist device that pumps blood from the left ventricle (LV) into the ascending aorta and would be responsible for systemic circulation. 

The goal is to implement three electrodes into a commercially available pLVAD with the intention of measuring the volume in cardiac output (CO) to obtain accurate measurements and perform calculations in real-time for automated pump weaning.

Scoli-Dynamic Brace | In the U.S, more than 600,000 adolescents with scoliosis go to private doctors each year. Current treatment options for scoliosis include continuous observation by a physician, bracing for teens and children, and surgery for extreme cases. According to estimates, about 30,000 children are given braces to treat their scoliosis each year, which in most cases, is only given to a patient that has a Cobb angle of 25-45 degrees. Current brace technology is static, rigid, and non-breathable which causes the patient to be non-compliant with the physician’s instructions on the amount of time the brace needs to be worn. Our mission is to bring to life a scoliosis brace that will tackle these design flaws and make a brace that is lightweight, increases the patient’s range of motion, and is made of materials that are breathable to tackle patient compliance issues.

Chemical Engineering Design II

Production of Biodiesel Through Transesterification of Waste Vegetable Oil Feedstock | This proposal is introducing a new biodiesel plant located in Houston, Texas. Biodiesel production will be done through a transesterification process. The process will start with waste vegetable oil, sodium hydroxide as the catalyst, and methanol. Once the transesterification of the mixed reactants is completed, it will result in glycerol and biodiesel as byproducts. A detailed simulation was run where stream tables and plant economics were obtained. The conceptual designs of specific equipment sections and a process flow diagram are mentioned in detail for the process. The utilities, safety measures, and the economic analysis for the whole plant are included.

Biodiesel Production via Transesterification | Biodiesel is an alternative renewable fuel, derived from vegetable oil or animal fat. This sustainable product is seeing a rise in production and consumption, causing it to be the subject of more and more research. Our team of student chemical engineers were able to develop and optimize a process for producing 10M ton/gal of biodiesel in an economically and environmentally conscious manner. For this project, canola oil feedstock was utilized with methanol at a 1:6 molar ratio with the addition of a heterogeneous catalyst, calcium oxide (CaO), to produce fatty acid methyl esters (FAME) via transesterification.

Biodiesel Production and Separation Via L-L Extraction | The project developed simulates the process of creating M-Oleate (Biodiesel) from recycled soybean vegetable oil, methanol, and NaOH. Through this design a developed process simulation was created with 93.27% conversion of soybean to biodiesel. Furthermore, the design covers an economic and safety analysis to determine whether the developed design is feasible for production. 

Production of Dimethyl Ether Utilizing Carbon Dioxide from Natural Gas | As CO2 emissions are expected to increase significantly over the following years, carbon capture and utilization is becoming an increasingly more important issue. This project establishes a process to convert CO2 from a commercially nonviable natural gas well in New Zealand to DME, a profitable chemical product, while taking into consideration health, safety, and environmental factors. In accordance with these goals, the CO2 is converted to DME by direct synthesis. The process is modeled in Aspen HYSYS and results in DME product purity of more than 99%. The associated economic analysis indicates the process to be profitable.

Production of Methanol from Natural Gas | R & A Engineering has been awarded to explore the natural gas field located in Conroe, Texas to develop the methanol production plant using the catalytic process with natural gas and steam as feedstock that is compliant with environmental health and safety guidelines. Production capacity was estimated to be 3000 MMSCF/day, the gas composition had 46.6% methane (CH4), 24.95 % CO2, and hydrogen sulfide (H2S) the remaining composition consisted of a mixture of hydrocarbon species. The process scheme to produce methanol is presented and accessed via Aspen HYSYS simulation where the natural gas was converted to a syngas mixture that was circulated under pressure and temperature and in return was converted to crude methanol that has been distilled to yield the commercial methanol. Market demand and supply analysis that included the feedstock, products, process routes, and market cost was conducted thus satisfying the requirements established by the Department of Energy while minimizing the cost and ensuring process safety in every step of production.

Natural Gas to Dimethyl Ether Product Synthesis | Carbon dioxide (CO2) is nonflammable and therefore large quantities are undesirable in a fuel. Additionally, both hydrogen sulfide (H2S) and CO2 form a weak, corrosive acid in water. Although many natural gas sources are free of nominal amounts of H2S and CO2, an increase in discovery of natural gas wells with significantly high levels of CO2 have created a growing interest in upgrading CO2 to viable specialty market products. In this work, initial market research was conducted, and a refining process for a final product of dimethyl ether (DME) was designed and simulated. A natural gas stream with a concentration higher than 20 mol% of CO2 was used as feed. Amine sweetening was optimized with a 30 wt.% concentration of diethanolamine (DEA). Sweetened natural gas was converted to syngas and fed with the purified CO2 to produce methanol (MeOH) via a non-catalyzed pathway, achieving a 99.99% purity, to dehydrate and react to the final product of DME. Initial findings suggest that previously designated “sub-quality” natural gas sources can become commercially viable as a diesel fuel alternative and feedstock for other specialty chemicals.

Production of Biodiesel from Waste Cooking Oil via Alkali Catalyzed Transesterification | Second Life Biofuels seeks to advance biodiesel production from used waste cooking oil (WCO). The process begins at a pre-treatment phase where oil is filtered and undergoes an acid esterification reaction to reduce free fatty acid content (FFA). This allows for high-quality feed and increases biodiesel yield later in the process. At this point, refined WCO is directed to the main reactor where it experiences base catalyzed esterification, yielding among other things biodiesel and glycerol. In the final stage of the process, a series of separators serves to refine the desired biodiesel product from unwanted side-products.

Carbon Dioxide to Methanol | Significantly high concentrations of carbon dioxide (CO2) in a gas stream is deemed “commercially nonviable”. This plant design has taken an interest in developing the natural gas and utilizing the available CO2. The well production capacity was estimated to be 3000 MSCF/day and the gas composition is composed of 46.6% methane (CH4), 24.95% CO2, 1.5% hydrogen sulfide (H2S) and the remaining composition consists of a mixture of hydrocarbon species. After analyzing the gas composition, available technology, safety, global market analysis, and a simulation optimization on Aspen HYSYS, methanol is a product that is favorable to manufacture.

Biodiesel Production by Transesterification of Vegetable Oil | There are many advantages when it comes to considering biodiesel over petroleum diesel, to name a few: less environmental damage, less flammable, and safer production process as well as use. Design and future implementation and construction of the production plant for biodiesel fuel through a transesterification process, using the Aspen Plus program. Initial components were Methanol, Water, Sodium Hydroxide, Glycerol, Triolein, M-Oleate, Sodium Methoxide, Diolein, and Glyceryl Monooleate. After the process simulation is carried out, the resulting product is biodiesel, with glycerol as the byproduct.

Currently, cleaning beer lines is done on average every two weeks and with this set in-place system, it saves the user time and money by reducing risk of having a bad beer and eliminates the use of harmful chemical sanitization techniques.

Game Board | Cornhole has been an incredibly popular game that has gathered more views for it’s professional league than Major League Baseball and the WNBA. Despite its popularity, we believe cornhole still has room for improvement. Score keeping is a very common problem, particularly in unofficial settings, such as parks and bars, and the board often proves unwieldy and hard to transport. Cornhole also lacks the common features of modern games which we wish to include to create a new game with more engagement and longevity.

Drone Conversion Appliances | The Drone Conversion Appliances team (DCA) has created a proof-of-concept novel drone design for the Unmanned Systems Laboratory that allows a user to easily switch between the traditional Quadcopter flight mode and the Fixed-Wing VTOL flight mode.
