Most modern blood pressure cuffs use the oscillometric technique, in which the cuff measures one value (mean arterial pressure) and an algorithm calculates systolic and diastolic blood pressure readings. However, this indirect method can produce inaccuracies, and single-point measurements lead to an inaccurate hypertension diagnosis in 30% of patients. While intraarterial lines can be used for direct and continuous blood pressure readings, they are highly invasive and reserved for inpatient use. ViTrack is different: it is a direct, continuous, yet non-invasive way of measuring systolic and diastolic blood pressures. “We...

One big reason there's a shortage of face masks that can block the spread of the COVID-19 virus is that they're single-use devices. The exterior may be contaminated and there's a good chance that keeping the mask and using it again could transmit the infection, particularly when masks are used around known COVID-19 patients. Because the filters inside N95 masks, that are now being widely used by medical professionals, utilize electrostatic activity to trap particles, washing these devices destroys their filtration capabilities. Engineers at KAIST, one of South Korea's finest...Read More

While face masks that block particles from coming into the lungs via the nose and mouth are important to prevent the spread of COVID-19, the eyes and the rest of the face can also be a pathway for the disease to find its way into the body. There are now a number of projects around the world, big and small, manufacturing breathing masks as fast as they can. A group of designers and engineers in New York City with access to a machine shop has designed a face shield that...Read More

Researchers at the University of Massachusetts Amherst have developed a portable AI device that can listen for coughs and sneezes and count the number of people present in public places to make predictions about levels of flu-like illnesses. The system, called “FluSense,” could be useful in the current COVID-19 pandemic in helping researchers to monitor the situation and determine where and when intervention is needed most. Successfully addressing the COVID-19 pandemic and future events of similar magnitude may require new surveillance technologies to monitor the spread viruses. In many countries...Read More

EchoNous announced that it has received the Eurepean CE Mark of approval for its Kosmos platform, an ultrasound and AI-based software system that helps physicians obtain diagnostic imaging and make clinical decisions at the bedside. The Kosmos platform consists of an eight-ounce ultrasound device, the Kosmos Torso, which also has ECG and digital auscultation functions. It is connected to the Kosmos Bridge tablet, which runs AI-based software that analyzes the ultrasound images to assess heart and lung function more quickly and accurately. Currently, the company is focused on using the...Read More

Carpal tunnel syndrome is a fairly common diagnosis in the United States, affecting approximately three to six percent of adults. Symptoms include pain, numbness, and tingling along the thumb, index, and middle fingers. For severe or refractory cases, the best treatment is surgery. However, because open surgery requires anesthesia and many weeks of downtime, most of the patients who are recommended for surgery do not receive it. That’s where Sonex Health comes in. The company’s SX-One MicroKnife and ultrasound-guidance are used to perform the carpal tunnel release. Using this minimally-invasive...Read More

Living cells inside our bodies are normally surrounded by an extracellular matrix, a supporting structure, that contains substances such as collagen and enzymes that help cells to function properly. When disease, particularly cancer, is present, the extracellular matrix tends to stiffen. This stiffening can be an indicator of disease arrival and its progression, but performing a stiffness test at very small scales without injury to the cells and their extracellular matrices has proven difficult. Now, researchers from Purdue University are reporting in journal Lab on a Chip on a new...Read More

Because of the COVID 19 situation, clinical facilities are currently faced with the issue of trying to keep interactions between potential patients and staff at a minimum. Face masks and other precautions help, but modern technology is allowing some tasks to be completely performed without human staff. Wegree, a company based in Poland, makes humanoid robots that are typically designed to greet people at stores, malls, and other consumer-facing businesses, and to answer their questions. Now, Wegree has adapted its robots to serve as check-in staff for hospitals and clinics,...Read More

As hospitals around the world are getting swamped with patients due to the COVID-19 outbreak, there are issues with having clinical facilities becoming easy havens for the disease to spread. Something that technicians with access to 3D printers can now quickly do is turn standard door handles into the kind that can be opened with one's arm rather than the hand. Materialise, a company that normally offers advanced 3D printing services for medicine and other fields, has just released a 3D printing file to create plastic attachments for common kinds...Read More

Researchers at Intel Labs and Cornell University have utilized an unusual "neuromorphic chip" to quickly learn the signature smell of ten different hazardous chemicals and spot their presence quicker than ever before. The Loihi chip, as it is called, mimics how our brains classify and identify unique smells that our noses detect, retaining a memory of a particular chemical after only a single exposure to its smell. Existing technologies that perform similar feats require hundreds or thousands of exposures to a chemical before finally learning to identify it consistently. “We...Read More

One of the biggest hurdles for America in its fight against the growing COVID-19 pandemic is a massive shortage of tests to diagnose for the virus. To help in the battle, one of the nation's leading at-home lab testing companies, Everlywell, has developed an in-home test for COVID-19 that also utilizes telehealth consultations with board-certified physicians. According to Everlywell, the tests will cost $135, with the company receiving no profit from sales. Consumers simply collect a sample in the comfort of their homes, preventing potential exposure to themselves and the...Read More

Ethos Medical, a startup founded by Georgia Tech alumni, has developed the Iris needle guidance system to assist clinicians in successfully performing lumbar punctures. The system allows a clinician to visualize the needle traveling through tissue in real time. Tracking the needle path in this way is intended to improve the success rate and reduce the chance of complications in such procedures. Lumbar punctures are used to diagnose several diseases, including multiple sclerosis and meningitis. However, they aren’t always straight-forward, with certain patients posing a unique challenge to clinicians because...Read More
