Published 2019-04-02 by SAE International in United States
Crash safety researchers have an increased concern regarding the decreased thoracic deflection and the contributing injury causation factors among the elderly population. Sternum fractures are categorized as moderate severity injuries, but can have long term effects depending on the fragility and frailty of the occupant. Current research has provided detail on rib morphology, but very little information on sternum morphology, sternum fracture locations, and mechanisms of injury. The objective of this study is two-fold (1) quantify sternum morphology and (2) document sternum fracture locations using computed tomography (CT) scans and crash data. Thoracic CT scans from the University of Michigan Hospital database were used to measure thoracic depth, manubriosternal joint, sternum thickness and bone density. The sternum fracture locations and descriptions were extracted from 63 International Center for Automotive Medicine (ICAM) crash cases, of which 22 cases had corresponding CT scans. The University of Michigan Internal Review Board (HUM00043599 and HUM00041441) approved the use of crash cases and CT scan data.The sternum morphomics data showed the thoracic depth increased, except for the 60-74-year-old age group.…

Published 2019-04-01 by Tech Briefs Media Group in United States

A transparent test patch, printed with harmless molecules, signals food contamination as it happens. The patch can be incorporated directly into food packaging, where it can monitor the contents for harmful pathogens such as E. coli and Salmonella. The new technology has the potential to replace the traditional “best before” or expiration date on food and drinks.

 

Chip Measures Quantities with Quantum Precision

Many devices use light to probe the quantum states of atoms in a vapor confined in a small cell. Atoms can be highly sensitive to external conditions, and therefore make superb detectors. Devices based on light interactions with atomic vapors can measure quantities such as time, length, and magnetic fields, and have applications in navigation, communications, medicine, and other fields. Such devices generally must be assembled by hand.

 

Fast, Flexible Ionic Transistors for Bioelectronic Devices

Published 2019-04-01 by Tech Briefs Media Group in United States

Many major advances in medicine, especially in neurology, have been sparked by recent advances in electronic systems that can acquire, process, and interact with biological substrates. These bioelectronic systems, which are increasingly used to understand dynamic living organisms and to treat human disease, require devices that can record body signals, process them, detect patterns, and deliver electrical or chemical stimulation to address problems.

 

Digital Manufacturing Helps Medtech Firm's Goal to Improve Patient Outcomes

  • Magazine Article
  • TBMG-34261
Published 2019-04-01 by Tech Briefs Media Group in United States

As often happens in the medical industry, innovative ideas hatched in university research settings spawn innovative companies, which create innovative products. A case in point: HemoSonics. The Charlottesville, VA-based medical device company was started in 2005 by two professors and a post-doctoral research student at the University of Virginia School of Medicine's Bio-Medical Engineering program — Bill Walker, Mike Lawrence, and Francesco Viola, respectively. The trio identified a method for measuring the stiffness of blood clots by using ultrasound imaging technology and created a system built around that technology aimed to improve patient outcomes and reduce costs.

While a wide variety of computer-controlled exercise machines for training and rehabilitation exist — some of which can be automatically adjusted to vary resistance or incline — such systems provide for preprogrammed changes in load or resistance. What is needed is a system that overcomes the limitations of the existing robotic rehabilitation systems by providing a training and/or rehabilitation system that adapts a resistance or force applied to a user-interactive element in response to the user's interaction.

 

3D Printed Implant Promotes Nerve Cell Growth to Treat Spinal Cord Injury

Engineers at the University of Maryland (UMD) have created the first 3D printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction — a critical feature for products like implantable devices that release therapies directly into the body.

Over the past few years, healthcare organizations have increasingly become one of the leading targets for cyber criminals with data breaches exposing personal patient data, medical records, and financial information, resulting in millions of dollars of added cost to these institutions. As the healthcare organizations become savvier with their cybersecurity, the criminals just get more creative.
