Diagnostic devices
-
Pharma giant Pfizer has shelled out nearly US$120 million to acquire a small Australian company claiming to have developed a smartphone app that can accurately diagnose COVID-19 by analyzing the sound of a cough.
-
New research points to an eye response to light as a potentially useful way of diagnosing autism in young children. Further testing is underway in a large cohort of children and a simple device to screen pupil responses has been developed.
-
Although there are now a number of skin-worn sensors which identify metabolites in sweat, the technology is limited in what it can detect, plus the sensors often aren't reusable. A new one, however, utilizes a "molecularly imprinted polymer" to be much more useful.
-
An innovative new rapid test promises to give people the ability to easily measure their COVID-19 immunity. The test tracks levels of neutralizing antibodies in a drop of blood, helping a person evaluate their susceptibility to SARS-CoV-2 infection.
-
While medical electrodes are vital to the monitoring of electrical activity in the body, they're rigid and costly, plus they don't stay on well if the wearer is moving. A new sugar-cube-derived electrode, however, addresses those shortcomings.
-
Ordinarily, the lung function of patients with respiratory problems is monitored via a stethoscope, during a visit to a clinic. An experimental new vest, however, can do the same job throughout the day, wherever its wearer goes.
-
Presently, in order to check if someone has chronic kidney disease, a urine sample has to be sent off to a well-equipped lab for testing. A new portable device, however, could allow such testing to be performed onsite in remote communities.
-
When rescuing avalanche victims or other people in cold, snowy outdoor conditions, it can be difficult to monitor their vital signs via traditional means. The MedSENS device was created with that fact in mind, as it simply goes in the ear and gets strapped to the head.
-
Presently, in order to check electrolyte levels in newborn babies, blood samples are drawn from the infants twice a day. Soon, however, a "smart" pacifier could be used to non-invasively collect that same data.
-
A new direct-to-consumer test designed to detect a number of different respiratory viruses including COVID-19 and influenza has been authorized by the FDA. The test is the first of its kind to be approved that doesn't need a prescription from a doctor.
-
When treating patients for certain conditions, it's important to monitor their blood oxygen levels. A new sub-dermal photosensitive sensor provides a new means of doing so, plus it could one day be used to measure other blood-borne substances.
-
The U.S. Food and Drug Administration has approved a new test for Alzheimer’s disease. The test is the first in vitro diagnostic tool for Alzheimer’s to be approved for use in the United States measuring amyloid protein levels in spinal fluid.
