BIBLOC: Bite Block Redesign

Approximately 14.5 million orally invasive imaging procedures such as endoscopy, echocardiography, and bronchoscopy are performed annually in the U.S. A bite block is a single-use medical device designed to keep the mouth open during such imaging procedures. Unfortunately, commercially available products suffer from structural and/or material challenges that tend to result in unwanted complications such as patient injury (i.e. the bite block is too stiff and injures patient’s teeth) and equipment damage (i.e. the bite block gets dislodged and the patient bites down on the imaging device). BIBLOC is a redesigned bite block that is the result of numerous design iterations each taking into account surveys from various stakeholders and material properties testing. BIBLOC is an easily securable bite block providing dual protection of both the patient and the imaging equipment.

Continuous Monitoring of Fetal Well-being

Resource-limited countries have a stillbirth rate that is approximately 10 times greater than that of developed countries. One in four of these stillbirths, along with newborn deaths in resource-limited countries, can be attributed to oxygen deprivation during labor and delivery. The continuous monitoring of fetal heart rate and maternal uterine contractions is essential for diagnosing such fetal distress early on. To satisfy the unique needs of hospitals in resource-limited settings, this low-cost, consumables-free solution of continuous monitoring of fetal well-being utilizes an electrocardiogram to detect fetal and maternal heart rates, as well as an electromyogram to measure the uterine muscle contractions.

FlushCut

Nearly 10,000 patients are diagnosed with T4 oral cancer of the lower jaw each year in the U.S. To treat this aggressive form of cancer, the fibula bone is removed from the patient’s leg and reconstructed to replace the affected mandible. The current technique used to reconstruct the mandible from the fibula utilizes tongue depressors to measure and notate where the fibula ought to be cut -- a tedious and time-consuming process for a procedure that can take up to 12 hours to complete and can cost upwards of $100,000. FlushCut is a tool that can be used to aid in the precise cutting of the fibula with three degrees of angular and linear freedom.

In-Home Biofeedback for Pediatric Urinary Incontinence

Pediatric urinary incontinence (UI), involuntary emptying of the bladder, affects more than 20-million people in the U.S., and 1 in 10 children will suffer from UI. In children with persistent UI that has not responded to conservative management and other directed therapies, an alternative form of treatment that has been shown to be very effective is biofeedback, or pelvic muscle floor training via the use of electrodes to measure muscle activity and provide feedback on the contraction and relaxation of the muscles. However, because these biofeedback devices are currently limited to clinical use, the outcome from biofeedback depends on the family's ability to travel to the hospital, pay for the therapy, and motivation of both the family and the child to participate in the unmonitored home-based training. This in-home biofeedback solution offers a creative in-home, mobile-based solution to clinical biofeedback with the use of electromyography with wireless transfer to a game-based biofeedback app specialized for children.

Load-a-Dose: An Automated Insulin Loading Device

The proper administration of insulin is imperative for the nearly 422 million adults worldwide that are affected by diabetes. Older populations of diabetes patients are twice as likely to suffer from vision impairment compared to younger patients, and are also more susceptible to dexterity challenges. To address the needs of diabetes patients with limited vision and/or dexterity, Load-a-Dose features an automated insulin loading mechanism, with audio and visual feedback.

Tele-Cystoscopy

Bladder cancer is the sixth most common and most expensive cancer to manage in the U.S. The primary method for bladder cancer diagnosis is via cystoscopy, the visual imaging of the bladder by insertion of a scope with a camera through the urethra by a trained urologist. With less than 12,000 urologists in the U.S., there is an immense lack of access for cystoscopy procedures in rural areas. The tele-cystoscopy solution aims to lower the operating skill threshold, decrease procedure costs, and increase accessibility of cystoscopies with semi-automated rotation and bending of the scope, as well as continuous video capture and stitching of images to provide urologists with a view of the entire bladder.

Automated Continuous Bladder Irrigation

Continuous bladder irrigation (CBI) is a process in which a nurse flushes saline through the bladder in order to wash out blood and prevent clotting after urologic surgeries. If a clot forms, it can make it impossible for the patient to urinate and lead to an extended hospital stay. CBI is performed on more than 150,000 patients per year in the U.S, but it is a manual process that requires a high level of monitoring from a nurse. This CBI device automates the process by detecting the level of blood in urine and managing saline inflow accordingly.

The ACBI team won the JARL award in 2017 and the Fenwick & West third place prize in 2018 at the Hollomon Health Innovation Challenge.

Cardiac Arrest Monitor

Cardiac arrest is the leading cause of death among people over 40. The treatment for cardiac arrest is CPR or defibrillation. The trick is to catch cardiac arrest quickly in order to treat the patient immediately, because the mortality rate for cardiac arrest victims increases by 10% for every minute that action is not taken. To monitor for cardiac arrest, EKG machines or SPO2 monitors are used, but these devices exhibit inaccuracies. This new cardiac arrest monitoring device uses ultrasound Doppler technology to monitor the carotid artery, which allows for quick and accurate recognition of cardiac arrest.

Enteroatmospheric Fistula Isolation

An enteroatmospheric fistula (EAF) is a hole between the gastrointestinal tract and an unhealed wound, and thus the open air. Between 1,000 and 4,000 cases occur annually in the United States, with a mortality rate of over 40%. EAF leak interstitial fluid into the wound, which hampers the healing process. Current methods to heal the abdominal wounds surrounding EAF are time consuming to install and don’t last long. This fistula isolation device is easy to install, stays in place once installed thanks to the silicone microbeads that fill it, and allows fluid to flow out of the body without irritating the wound bed.

Intravenous Arm Trainer

Over 200,000 IV catheters are placed daily in the United States; however, there is a 50% fail rate for correctly placing the catheter on the first needlestick. Healthcare students need to be able to train to place IVs, but existing arm trainers lack anatomical and physiological accuracy. As a consequence, students resort to practicing on other students or on patients, which poses an infection risk. This new arm trainer has a unique four-layer tissue and rolling vein behavior that provide the most realistic training experience possible for students.

Mouthshield

Traumatic dental injuries are costly and have life-long consequences, but they can be prevented by wearing a mouthguard. Existing mouthguard solutions that can be worn by people with braces are bulky and uncomfortable, and they can make breathing and speaking difficult. This discomfort leads athletes to avoid the use of mouthguards, which makes them susceptible to injury. The Mouthshield is an adaptive braces mouthguard that is low profile and comfortable to wear, while still protecting the wearer from dental injuries.

Venous Ulcer Compression

Venous ulcers, which affect 1% of the adult population, are painful open sores that occur when veins are unable to correctly pump blood out of the leg and fluid pools. Compression is the most common form of treatment, but compression bandages are applied by clinicians to ensure proper fit, are not reusable, and must be replaced weekly. Some current compression devices don’t require a clinician to apply, but they are not usable by low strength or limited mobility patients. This new compression device is easily applied and adjusted, using a Boa Technology knob and wire system, and includes an active pressure feedback system to optimize healing.

Improved Percutaneous Gastrostomy Tube

Gastrostomy tubes (g-tubes) enable patients to receive adequate nutrition who otherwise could not. G-tubes that are placed through the skin percutaneously have a tendency to dislodge, necessitating an unanticipated and expensive clinical procedure. This new g-tube design can be placed percutaneously and has improved retention. The resulting g-tube design features a bell that crushes for easy insertion and then inverts to provide superior retention.

Parastomal Hernia Support Harness

Patients who have undergone gastrointestinal stoma formation surgery are at high risk for parastomal hernias. Specially designed support belts help prevent patients from forming hernias, but existing belts are ineffective, uncomfortable, and difficult to don. This improved hernia support harness is easy to use and stays in place when the wearer moves. A foam disk on the inside of the belt distributes the force on the abdomen, and the wearer can adjust the force applied to hernia-risk regions with the simple turn of a dial. The prototype development of this project continues and human subject studies are soon underway.

PlayGait

Children with gait disorders tend to spend limited time walking outside of physical therapy, which can slow their rehabilitation rate. PlayGait is a pediatric exoskeleton that helps children with gait disorders walk more, so they can establish efficient gait patterns and reduce their rehabilitation time.

Since completing EIH, the PlayGait team has received grant funding for further research and development and has filed for a patent through UW CoMotion. PlayGait won third place at the 2017 Hollomon Health Innovation Challenge and is a semifinalist in the 2017 Business Plan Competition. The PlayGait team is currently preparing to test with patients and is planning for a controlled initial product release in 2018.

Sole Train

People with limited mobility due to neurological disorders are commonly prescribed rocker sole orthoses to improve walking ability and encourage a natural walking motion. The current process for making rocker soles is costly and time-consuming due to the iterative nature of determining the optimal rocker shape. Sole Train is a rocker sole that features a PVC cushion that can be easily adjusted before the air is evacuated from the cushion, leaving a rigid sole that can withstand the forces of walking.

Walk ‘n’ Roll

Falling is the sixth leading cause of death for individuals over 65. Four-wheeled walkers help reduce falls if they are used properly; however, accidents are frequent when individuals move down hill or transition from sitting to using the walker. Many individuals who have been prescribed walkers abandon them because their walker is not meeting their needs. Walk 'n' Roll is an improved walker solution that addresses the ergonomic and safety concerns that contribute to walker disuse and frequent accidents. Walk 'n' Roll promotes proper posture, decreases wrist pain, and features speed control and advanced stability control.

Clot Failure Diagnostic

During emergency situations, it is important to measure blood clot strength in patients with trauma-induced coagulopathy (TIC), a condition where the blood’s ability to stop bleeding by forming clots is impaired. Healthcare providers need to be able to determine the ideal applied blood pressure to mitigate the effects of TIC. This point-of-care diagnostic device can measure clot failure pressure on-the-go in emergency situations. This project continued as a research project in the lab of Dr. Nathan White.

Lung Biopsy Needle

Lung biopsies are performed to diagnose lung cancer; however, biopsy needles can cause pneumothorax (collapsed lungs) due to positive pressure in the space between the lung and the chest wall. This needle includes a vacuum port to suck out the air leaked into this space and prevent pneumothorax. The vacuum remains in place after the biopsy to ensure the lung stays expanded during healing.

Neonatal Intubating Laryngeal Mask Airway

Thousands of infants require oxygen after birth each year. The most common and secure way to provide assistance is intubation, where a tube is passed through the vocal cords into the trachea to provide a secure airway to deliver oxygen using a mechanical ventilator. It is difficult to intubate neonates because of the size and position of their vocal cords. Laryngeal mask airways (LMA) are more easily placed than intubation tubes; however, they are not considered a secure airway that can be used for extended periods. The Neonatal Intubating Laryngeal Mask Airway device can be quickly placed to provide life-saving oxygen to a newborn and then can be simply transformed to a secure intubation tube with no interruption in oxygen flow.

Septic Shock Diagnostic

Septic shock is a significant cause of mortality in low and middle income countries. Capillary refill time (CRT) is the time required for natural color to return to the skin after pressure is applied to induce blanching (whitening). CRT measures perfusion, the body's ability to supply blood to vital organs. CRT has been shown to correlate well with early indicators of septic shock. This device uses the camera and processing power of a mobile phone to easily and accurately measure CRT.

Advanced prosthesis socket

The prosthesis socket used by trans-tibial amputees compresses the residual limb. When the prosthesis wearer walks, the same force that keeps the prosthetic socket in place squeezes the limb, causing the residual limb to shrink in volume. This decrease in volume results in an uncomfortable, ill-fitting socket. This advanced prosthetic socket has a clamshell design that allows wearers to remove the back-half of the prosthetic, without removing the entire prosthetic, which encourages residual limb volume recovery.

Flexible Biopsy Needle

Lung biopsies are necessary to diagnose lung cancer, but biopsy methods vary in their invasiveness. To access tumor biopsy samples in peripheral regions of the lungs, healthcare professionals must insert a needle through the chest wall instead of using a less-invasive transbronchial method. This flexible biopsy needle allows healthcare professionals to access hard-to-reach tumors via a less invasive bronchoscope.

Heart Anchors

Patients with heart disease who are unable to undergo open-heart surgery can instead be treated with a minimally invasive, catheter-based surgery. In this surgery, a clip device is maneuvered via a catheter into the compromised heart valve, but it is difficult to maneuver the clip within the dynamic environment of the heart. Heart Anchors are an inflatable balloon stability system that guides clip equipment and makes it easier to place the clip within the valve.
