Work-related musculoskeletal disorders are generated, preceded, or aggravated by repeated or continuous use of certain parts of the body. Orthoses have been developed to help people prevent or treat these kinds of disorders. In this paper, we developed a novel flexible orthosis based on bend sensors to count the times of the repetitive movements and remind the worker to take adequate rest after a period of repetitive movements, thus, to reduce the possibility of developing musculoskeletal disorders. A novel movement detection method is developed to count the times of the repeating movement by using the trends/slopes of the rotation angles. Experiments have been conducted to evaluate the accuracy of the novel movement detection method. The results demonstrate that the movement detection method can accurately count the times of the wrist movement with varying rotation angles and speed and issue reminders for rest.

Optical coherence tomography (OCT) is an advanced imaging modality to detect Barrett’s esophagus (BE) dysplasia, providing widefield, cross-sectional imaging and microscopic resolution. BE dysplasia is characterized under OCT by the presence and number of glandular structures with atypical morphology. Accurate detection and interpretation of BE glands under OCT is essential to detect dysplastic lesions. Object Detection using deep learning has the potential to identify glands from OCT images. We developed a YOLO model to identify the presence of glands in BE tissue. The YOLOv4 object detector was trained on a custom BE dataset of 30 patients with confirmed BE who underwent OCT imaging, of which 222 OCT images included at least one gland. Our model identified glands with a high average precision of 88.79% on the test dataset. We showed that the developed model is robust to rotation, brightness, and blur in images. We have implemented an object detection model to identify glands from OCT images with promising results accurately. This model has the potential to improve the diagnosis and surveillance of BE by eliminating human error and missed dysplastic lesions adaptable for capsule endoscopy applications.

Capillary refill time is the time it takes for blanched skin tissue under pressure to return to its normal state when that pressure is released. The test is commonly performed on the fingertip by clinicians to assess for signs of septic, traumatic, or hypovolemic shock. Current methods of capillary refill time measurement are typically subjective, coarse-grained, and clinician dependent. A more standardized and objective measurement of capillary refill time has been shown to improve the diagnosis of pediatric dehydration but has typically required specialized equipment. We have developed a digital version of the capillary refill test utilizing only a smartphone to increase access to capillary refill assessment. Our aim is to determine the accuracy and precision of this smartphone-based measure in a population of healthy pediatric subjects.

Compression devices are widely used in fields such as astronautics, cosmetics, and medical therapy for treatment of various diseases such as Postural orthostatic tachycardia syndrome (POTS) and Orthostatic Hypotension (OH). Unlike traditional compression devices that apply static pressure on the body, there have been some efforts to integrate smart materials such as shape memory alloys (SMAs) to make compression garments active and controllable. SMA-based compression systems can be made in tourniquet (band) and knit (larger area) forms. SMA Knits are typically activated through direct heating approaches that may not be accessible in real-life applications. Unlike other forms of SMA actuators, due to the complexity of SMA wire interconnections in the knit, Joule heating has not been investigated yet. Hence, this paper presents an experimental protocol to electrically activate the SMA-knits through Joule heating. The designed protocol, include measurement of generated force, electrical properties, and temperature in a displacement control condition. The results of this study indicate that connecting the power leads to the middle of a knitted SMA sample along the course direction, can contribute to a better wide-reaching electrical pathway, and subsequently achieves better force generation through Joule heating.

Acute Respiratory Distress Syndrome (ARDS) is an acute inflammatory condition that causes impaired oxygenation and is almost always treated with mechanical ventilation. Positive End-Expiratory Pressure (PEEP) is an extrinsic pressure applied in ventilation to maintain alveolar opening. Esophageal manometry is a useful tool in titrating PEEP to ensure adequate ventilation is being provided in cases of increased chest wall pressure. However, few pulmonologists or critical care specialists utilize esophageal manometry routinely because of the required additional procedure, sparse training opportunities, and esoteric calculations required to perform the procedure and evaluate the results. We have designed, prototyped, and tested a device to simplify and reduce the time necessary to perform esophageal balloon catheterization. This device contains a balloon sleeve to be placed over a standard nasogastric tube which is capable of measuring the esophageal pressure while ventilation is being provided. Based on the esophageal pressures, a web based app created in tandem with the device calculates the desired PEEP for the ventilator settings to ensure adequate oxygenation of the patient. Statistical analysis demonstrated adequate similarities in trends compared to existing devices along with significance in pressure variability.

Infants spend most of the day sleeping anywhere. In the past, most parents put their infants to sleep in the prone position, but recently they put their infants to sleep in the prone position because of an issue of sudden infant death syndrome. When infants sleep in a supine position for a long time, occipital bone deformation is occurred because of pressure at the occipital region. To prevent minimize the pressure on the infant’s head and body, through the finite element simulation using the infant model, a baby cushion for the stroller was designed using the central composite design (CCD) method. The maximum contact pressure between the designed cushion and the infant model was 22.8 mmHg and this value is about 50 % lower than the pressure that occurred between the infant model and the general cushion. It can be helpful to reduce the possibility of a baby’s head deformation and other body disorders.

Coronary artery disease can be caused by partial or total occlusions of the coronaries, leading to cardiac ischemia. Today, the percutaneous implantation of stents is the most common treatment to open such blockages and thus restore oxygen delivery to the myocardium. Subsequent stent calcification or restenosis may hinder the effectiveness of these stents over time. The Visible Heart® Laboratories have a collection of 30 perfusion-fixed human hearts that had a total of 35 such intervention prior to organ donation. Micro computed tomography (micro CT) can be used to study the device-tissue interfaces of stents implanted up to decades prior to recovery. These procedures were scanned with approximately 40-micron resolution. Computational models were generated such that calcification and restenosis could be visualized and quantified. Within this unique data-set, there was a wide variety of stent length, location, and volume of calcification present. Although 90% of the cases had varying degree of calcification present outside the stent only 11% showed any degree of restenosis. This is a unique research opportunity to micro CT scan 35 cases of therapeutically implanted stents in perfusion-fixed specimens. Extensive visualizations and analyses can be performed on generated computational 3D models, so to provide for better understanding of the variations within the device-tissue interfaces of therapeutically implanted stents.

When patients experience heart failure, medical devices can support lost cardiac function. However, compliance mismatch between biological tissues and devices present challenges for long term integration. For example, silicone, a common polymer used in soft robotic medical devices, has negative side effects when implanted in vivo. This paper explores biomimetic properties of alternative materials by testing mechanical properties of polyurethane composites. Testing reveals similarities between our composites and native tissues in the heart and aorta. When built into fabric reinforced elastomeric enclosures (fabREEs), our composite actuators behave similar to native aortic tissue. By analyzing hoop and longitudinal stresses in actuators, we present candidate materials for building aortic models for use in transplantations or benchtop testing. We show that these materials can serve to mimic a range of cardiac tissues and that future of medical device design will benefit from considering these soft material composites in new devices.

Systematic 12-core prostate biopsy has been an established practice for prostate cancer diagnosis. The procedure involves extraction of a tissue sample from 12 zones of the prostate gland for pathologic analyses using at least 12 needle insertions. The procedure is usually performed using straight needles and under ultrasound imaging. We have previously developed an active tendon-driven biopsy needle that can bend inside tissue with teleoperative or robotic control. This work presents our active biopsy needle’s capability to reach 12 marked zones in a patient-specific prostate model, avoiding the urethra, with only two insertions in a transperineal prostate biopsy.

Chronic cough is not only one of the leading causes of seeking healthcare all over the world but also a huge emotional drain on the affected patient population. In this study, we used 24-hour cough recordings to analyze the intervening conversations for sentiment analyses to better diagnose, guide, and manage treatment in such patients. We surveyed a cough clinic and selected four subjects with active cough complaints using relevant ICD-10 codes. Subjects were given and instructed to wear a device to record cough for 24 hours and the recordings were collected at weeks 0, 4, 8, and 12 of the treatment. The collected data was preprocessed to eliminate sections with no data (sleep, silence) and the number of coughs was counted. Google search API calls were used to transcribe the audio files and NLTK’s VADER analyzer was used to classify sentiments on a scale of 0 to 1. Finally, average scores were calculated and plotted over a graph to interpret any trends. 12 weeks of cough treatment had varied results on the four subjects. We categorized the exhibited sentiments into negative, neutral, positive, and compound and noted that they also showed no general trends. Among these, the compound sentiment displayed the most erratic patterns, and the obtained results could not generate a steady trend. Further studies are required with a large cohort to collect data over a longer duration to accurately analyze the sentiments associated with chronic cough.
