User Centered Design

Ease of use is a critical aspect of medical device design. A device that can be operated intuitively is a safer device – chances of use error are significantly reduced. A device that is simple to operate reduces the cognitive load of the user, allowing them to concentrate on the task, not on the device. [...]

Design of Wearable Medical Devices

There has been some interesting news on the design of wearable medical devices recently. Rutgers University is developing a wristband that can access the blood stream and draw up samples via a micron-sized tube. Sensors on the band can count blood cells, bacteria, organic matter and particles in the air, providing the capability to monitor and [...]

Radar to Detect Blood Glucose Levels

Scientists at the University of Waterloo are working on a device that would use radar to determine blood glucose levels. By analyzing how the electromagnetic waves sent by a radar transmitter bounce off of a glucose solution, the scientists were able to detect minute changes in the properties of solutions with different levels of glucose. [...]

Where Medical Imaging is Headed

Most medical imaging technologies in widespread use today provide relatively low-resolution, black and white, 2-dimensional images that require significant training to interpret and understand. However, new technologies are being developed that are going to revolutionize medical imaging, allowing 3-dimensional, color images to be obtained. Some of those technologies can even yield video images in real [...]

Will Light be the Key to Curing Addiction?

Optogenetics is a tool that is being used extensively to learn how the brain works. In a study recently published in Nature, a research team was able to use optogenetic techniques to modify taste sensations in mice. By stimulating with light genetically altered areas of the brain, they were able to make the mice experience [...]

Poor Usability Leads to Device Recall

Poor usability in Draeger Medical’s JM-103 and JM-105 Jaundice meters has led the FDA to issue a Class 1 recall of the devices. A Class 1 recall is the most serious, and indicates that use of the device could cause serious injury or death. The Draeger meters measure yellowness of subcutaneous tissue in newborns. Measurements [...]
