Anemia is properly diagnosed using a blood test that measures hemoglobin, but simply looking behind a patient's eyelid can be a pretty good alternative if you know how red the tissue is supposed to be. Now, a team at Purdue University has developed a technology that lets a clinician use smartphone pictures of the inner eyelid to automatically obtain surprisingly accurate results of blood hemoglobin levels. This capability is expected to soon be fully integrated into an app that will perform the necessary image analysis. Unlike blood tests, smartphone apps...Read More
Researchers at Hokkaido University in Japan have developed a paper-based point-of-care device which can measure lithium levels in a drop of blood. The device could help patients with bipolar disorder to keep track of their blood lithium levels. Lithium carbonate is used to treat bipolar disorder, but must be administered carefully as the concentration range in which the drug is therapeutically active is close to its toxic range. This means that patients require regular blood tests to make sure that they are not receiving too high a dose of the...Read More
Nines, a teleradiology company based in Palo Alto, CA, recently received FDA clearance for their NinesAI medical device, which supports the automated radiological review of CT Head images for the possible presence of two time-critical, life-threatening indications: intracranial hemorrhage and mass effect. The technology can help radiologists in triaging cases. Nines is the first company to receive FDA clearance for AI technology that triages mass effect conditions. Teleradiology is an increasingly vital service for healthcare providers, whereby radiological images are sent to a radiologist in a remote location for analysis....Read More

As people are starting to return to work, school, and a more normal way of life during the ongoing COVID-19 pandemic, distancing will remain important for the foreseeable future. Companies, governments, and all kinds of organizations are developing, or already implementing, policies and procedures to help prevent new outbreaks of the disease. Lopos, a startup with origins at imec and Ghent University in Belgium, is releasing a wearable device that helps to implement social distancing protocols. The Lopos SafeDistance is a wearable that can accurately measure how far away it...Read More
Researchers at the University of California San Diego have developed flexible sensors that can be worn on the skin to sensitively track vitamin C levels in sweat. The devices could be useful in helping wearers to maintain optimal levels of the vitamin, which is important for a healthy immune system, and could be particularly useful for patients who are dealing with or recovering from an infection. Previous studies suggest that vitamin C may help to support recovery from certain aspects of COVID-19, and if the vitamin is shown to be...Read More
Falls have serious consequences for seniors, especially those who live alone. Medical alert devices can notify emergency services, but they are not always worn. In addition, they do not address fall prevention by encouraging active lifestyles and physical strengthening. WalkWise hopes to fill these gaps. The Fargo, ND-based company offers a smart device that can be attached to the wheels of most walkers. The device can alert family members to falls and it collects walker activity data. These insights could help families address inactivity and physical deconditioning proactively. We asked...Read More
Researchers at the University of California San Diego have developed a magnetic tracking system for surgical robots to operate with dexterity within the body. The technology does not require patient or clinician exposure to radiation, and is much less expensive that pre-existing monitoring techniques. A magnet is embedded in the tip of the robot and a series of sensors can track its location, while a neural network improves the accuracy of the tracking system. “Continuum medical robots work really well in highly constrained environments inside the body,” said Tania Morimoto,...Read More
The FDA has granted Philips 510(k) clearance for its ultrasound systems to be used to address lung and cardiac complications that arise in COVID-19 patients. The clearance encompasses the firm's EPIQ series, Affiniti series, Lumify, CX50 and Sparq diagnostic ultrasounds, and for offerings such as the QLAB Advanced Quantification Software. Ultrasounds can help to diagnose patients with signs of respiratory distress and portable ultrasounds, such as the Philips Lumify, can do so at the point of care. Not having to move patients around the hospital reduces the potential for disease...Read More
Telemedicine has been around for over a decade in various forms, but the COVID-19 epidemic has turned a convenience into a necessity. Clinical practices that never seriously considered using telemedicine are now performing virtual house calls with their patients. However, although it's possible to do a lot through a video call, many procedures such as ultrasound exams require a trained professional to perform them. Or so we thought... Butterfly Network, a maker of portable ultrasound wands that can turn a smartphone into a complete ultrasound system, has unveiled its Butterfly...Read More
Nevro, a Silicon Valley-based company, announced that it has received CE mark approval for its Senza Omnia Spinal Cord Stimulation (SCS) system for management of chronic pain. The device was FDA approved for chronic pain in November 2019. Nevro touts its device as the first and only that is designed to deliver all frequencies from 2 to 10,000 Hz, compared to the 1-1,200 Hz range provided by traditional SCS. The Senza Omnia can also simultaneously deliver both low and high frequencies to different parts of the spinal cord. The system consists...Read More
Researchers at Duke University have developed a fluid dynamics simulator that can model blood flow within the body, including the motion of individual blood cells. The researchers hope that the system could eventually be used by clinicians to model blood flow for individual patients and help with treatment decisions, such as stent placement. By testing various graphical user interfaces for the system, the research team learned that both a virtual reality system and a traditional computer were easily used by participants, but most preferred the VR interface, suggesting that it...Read More
