Deep Wound Sealant

MEMBERS: Molly Carlson; Rebecca Haverkamp; Sydney Maben; Megan Taflinger

ADVISOR: Dr. Kim Cluff

TABLE: 306

This is a medical device that will be inserted into deep wounds and will prevent death from hemorrhaging. The device has two parts: the applicator and the sealant. The applicator is made from sterilized plastic and resembles a tampon applicator. The sealant is comprised of a cotton wad inside the applicator. The cotton is coated with a zeolite compound that aids in blood clot formation. The zeolite compound is hypoallergenic, does not cause skin irritation, and does not pull out blood clots upon removal. The sealant will remain in the wound until removed by medical professionals and will leave no residue.

Adjustable Cranial Bands

TABLE: 304

Cranial bands are used to correct cranial deformities in infants. The most common cranial deformities are plagiocephaly and brachycephaly. The typical treatment time of cranial bands are between 6 and 12 months, if the treatment starts earlier, it will be a shorter treatment time. During this time the patient grows and needs a new helmet after about 6 months, however only the first band is covered by insurance. The solution to this problem is to create an adjustable cranial band mechanism that can be used to modify a custom helmet. The design that is proposed is one that consists of four quadrants threaded together using a BOA tm system. The helmet will be formed by an orthotist, cut into 4 quadrants, and then threaded together. This allows the cranial to be the exact shape needed to correct the cranial deformity and only expands and contracts circumferentially. This allows the caregiver to place and remove the helmet using the ratcheting system. A prototype was made and shows the overall functionality of the design, made at Hanger Prosthetics and Orthotics under the supervision of an Orthotist/Prosthetist (O/P). The prototype underwent testing to see the integrity and feasibility of the design.

Automatic Compression and Ventilation CPR Device

TABLE: 307

Over 350,000 out-of-hospital cardiac arrests (OHCA) occur annually in the United States. Immediate treatment, in the form of CardioPulmonary Resuscitation (CPR), is imperative to increase chances of survival. This consists of two stages: compression and ventilation. Manual CPR requires multiple persons to be available and can be difficult to perform during patient transfer. Automated CPR (aCPR) can provide reliable, safe treatment if the option is available. Current market aCPR machines are very expensive, and while they do provide automated compressions, they do not include automated ventilation, requiring unnecessary human intervention in this life-saving process. The goal of this project is to develop an aCPR machine that is more affordable, easy to use, and fully automated with ventilation so that more people who suffer an OHCA can receive life-saving treatment. The current work of Safe Hands Innovation is directed at finalizing a working prototype as well as developing experimental setups to test the functionality of the device.

Cooling System for Prosthetic Socket with Active Volume Compensation

TABLE: 308

An ideal prosthetic socket should be perceived as a part of the natural limb and should diminish further risk of injury. The primary focus of recent developments in prosthetics has been to improve daily-life activities. However, heat accumulation and perspiration inside the prosthetic socket have not been addressed commercially. In addition, methods for compensating the volume loss that occurs within residual limbs throughout the day have not been improved. The current method requires removing the socket completely to add or remove socks. Our project concentrates on the development of a system to increase prosthetic socket usability by reducing heat buildup, minimizing skin damage, and accommodating for volume fluctuation in the residual limb for prosthetic customers. A removable cooling system with active volume compensation requiring a one-time modification to the individual’s socket has been designed. This project provides innovation within the prosthetics field by introducing a novel prosthetic system capable of increasing comfort and safety with minimal modifications.

3D Printed Casts with Healing Technology

TABLE: 309

Roughly, 178 million people in the world and 6 million people in the United States sustain new bone fractures every year. These fractures result in nonunion, neurovascular injuries, and infections if left untreated. The current noninvasive solutions for fracture healing include fiberglass, plaster, and 3D printed casts. Fiberglass and plaster casts are inconvenient, uncomfortable, and not breathable. These casts are also not adjustable or removable to accommodate swelling and radiographic imaging during consultations. The current available 3D printed casts are better with their lightweight and breathable makes but they do not have advancements towards bone healing. Low intensity pulsed ultrasound was worked on as a healing mechanism previously; however, it did not pass the prototyping stage. Our cast provides a healing technology incorporated to it via iontophoresis. Iontophoresis is a way to deliver ions and proteins transdermally using electric current. The electric current has a dual action as electrical stimulation is also used in orthopedics to speed up bone healing time by 50-60%. Some of the proposed drugs for iontophoretic drug delivery are Teriparatide, calcium, and vitamin D. Along with electrical stimulation, healing time would be reduced by more than half the period it would take with the other solutions.

Walker Design for Fall-Prevention in Alzheimer's Disease

MEMBERS: Laik Bradley; Madison Carlgren; Marlene Kouakam; Jennifer Ramos-Melendez; Adonay Tedla

ADVISOR: Dr. Kim Cluff

TABLE: 305

Alzheimer’s disease (AD) is a neurological disorder that affects an individual’s cognitive and physical abilities, making falls extremely common. Older adults with Alzheimer’s disease have a 60 to 80 percent chance of falling each year. Present-day solutions for fall prevention rely on the usage of mobility aids, such as canes and walkers. The market for rollator walkers was valued at 72 million in 2021 and is projected to reach 139.5 million by 2026, with a compound annual growth rate of 5.8 percent. However, if an individual with Alzheimer’s disease were to use one of these devices, their likelihood of falling increases by three-fold. As mobility aids make falls more prevalent in those with Alzheimer's disease, the only devices utilized are specialty lifts to help caregivers move the person after they fall. Our goal is to move the solution for falls from being reactive to being proactive. We have designed a rollator that focuses on providing natural movement for the user in addition to an automatic braking mechanism. The three-wheeled structure, front Omni-wheel, and high handlebars allow the walker to move smoothly with the user. Safety is ensured by incorporating a mechanical pressure sensor that will automatically stop the walker if the individual loses balance. Unlike our competitors' designs, we have taken careful consideration of the impact Alzheimer's disease has on the ability to walk. Therefore, our mobility aid should reduce falls and fall-related injuries unlike other alternatives on the market.

TABLE: 143 (Lobby)

EMS providers have a highly demanding yet critical job which often puts them in dangerous situations and may leave them injured or unable to perform to their potential. Their workspace, the back of an ambulance, offers no stable surfaces which they can rely on to maintain balance while still being able to fully attend to the patient and reach all the necessary equipment to do so. Most type I and type III ambulances, which are most common in the United States, are also heavy enough that they are legally classified in the same class of vehicle as small buses, where passengers are not required to wear seatbelts. Because of this, and the restraints seatbelts impose on an EMS provider at work, EMS providers are almost always unrestrained in the back of an ambulance, and in many cases, the patient is improperly restrained and at a higher risk of further injury. A solution that offers EMS providers greater stability while performing their duties in a moving ambulance, as well as greater safety when the ambulance undergoes high acceleration is critical if this problem is to be solved so EMS safety and performance can be improved.
