Designing a More Patient-Centric Battery Holder

October 17, 2012 4:23 pm | by Tom Blaha | Memory Protection Devices, Inc. | Comments

  Powering portable devices is a critical element in healthcare today as more and more medical technologies are used in the home or on the patient directly. As such, patients are responsible for the power supply (i.e., batteries) more often than a healthcare professional. As such, a new innovation in battery holder technology makes replacing them easier, which is most important for the very young and elderly.

October 11, 2012 5:01 pm | by Mike Gaul, Al Hoffmann, Ruben Macias Jr., Tim Nakari, Chris Paolo, and Mike Treadway | Sparton Medical , Interplex Industries, Inc., Ximedica, The Tech Group, Inc. | Comments

Representatives from contract manufacturing companies serving the medical device community respond to questions including, "What is your best recommendation to ensure clear communication between the CM and the OEM?" "How do you alleviate concerns of the potential for you to work with a customer’s competitor?" and "How do OEMs benefit from CMs who develop products for other industries outside of medical?"

The Next Direction for Surgical Robotics

September 20, 2012 3:28 pm | by Kasey Panetta | Cambridge Consultants Inc | Comments

The world of medical technology has always been a rapidly changing and evolving field. Solutions for long plaguing problems, like reducing human error by using more robotics, begat more problems like an increase in mechanical failure during procedures. Plus, throw in rapidly aging baby boomers, an increase in global population, and a surge in demand for specialized doctors and the problems grow exponentially.

Gearmotors: Achieving the Perfect Motor & Gearbox Match

July 24, 2012 2:59 pm | by Seth Hulst and Loren Kamstra | Groschopp, Inc. | Comments

For electrical and mechanical design engineers in the process of developing applications, choosing a gearmotor can be a tricky and arduous process. Can motors and gearboxes be purchased separately and then matched for an application? Is it better to specify a pre-engineered gearmotor? What are the differences? By following the two gearmotor selection methods readers will receive a checklist of considerations to determine which process would be the most helpful and steps to complete the gearmotor selection process. There are many factors to consider when choosing a gearmotor.

Designing a Wound Dressing to Manage Burns

July 18, 2012 1:51 pm | by Steve Bishop, Wayne Bonnefin, and Lucy Ballamy | Convatec | Comments

It is estimated that one million burn injuries occur annually in the United States, resulting in 45,000 hospitalizations. The hands are involved with a large number of burn injuries, and partial thickness burns (PTBs) are among the most frequently-occurring types. A PTB is marked by the destruction of the epidermal cell layers of the skin, extending into, but not through, the dermis.
