Integrating Electrical Systems into 3D Mechanical Models

Real-time integration of 2D schematics and 3D models allows mechanical and electrical teams to better collaborate and deliver more accurate designs. Product development teams are under increasing pressure to engineer more complex products that combine numerous electrical systems within a single design, including visual interfaces, power systems, logic controllers, complex wiring and harnesses. Simplifying the design of these electro-mechanical systems using intelligent design tools, and a shared, comprehensive parts database, medical device designers are able to achieve significant cost savings. These savings are multiplied when this electrical design work is done in perfect synchronization with the mechanical and industrial design teams using a shared data model.

Defibrillator Setting Change Leads to Health Gains

Survival climbs, risk of unnecessary shocks plummets A new study at the University of Rochester Medical Center Rochester, NY, shows that defibrillators, which are designed to detect and correct dangerous heart rhythms, can be programmed to help users live longer, better lives, than they currently do.

Paralympian ‘Catapults’ to a Silver Medal

A new type of carbon fiber running foot helped propel an American sprinter to a medal at the London Paralympic Games. At London’s Paralympic Games in September, USA track and field star Richard Browne took the silver medal in the highly anticipated 100-meter race for below-the-knee amputees. The 21-year-old was the first athlete to train with and compete with the Catapult® Running Foot from his sponsor Freedom Innovations, LLC, Irvine, CA, at a Paralympic Games.

Wideband Single-Crystal Transducer for Bone Characterization

These transducers have uses in medical ultrasound imaging and room-temperature ultrasonic flow meters. The microgravity conditions of space travel result in unique physiological demands on the human body. In particular, the absence of the continual mechanical stresses on the skeletal system that are present on Earth cause the bones to decalcify. Trabecular structure decreases in thickness and increases in spacing, resulting in decreased bone strength and increased risk of injury. Thus, monitoring bone health is a high priority for long-term space travel. A single probe covering all frequency bands of interest would be ideal for such measurements, and this would also minimize storage space and eliminate the complexity of integrating multiple probes.

3D Scanning for Post-Mastectomy Custom Breast Prosthesis

Creating a custom breast prosthesis that feels and looks more natural can be accomplished. Breast cancer is a terrible affliction that affects approximately one in eight women in the US. In 2012, nearly a quarter- million cases of invasive breast cancer will be diagnosed among women. Due to the progress of medicine and associated treatment, the death rate associated with breast cancer has been declining since the 1990s to approximately 1 in 36 cases. At this time, there are more than 2.6 million breast cancer survivors in the United States alone. Different procedures can be attempted in order to treat and cure a cancer but the more advanced cases will sometimes need to undergo a complete mastectomy (a procedure in which a breast is removed entirely). A mastectomy is a rather radical procedure and some women may experience a post-surgical trauma due to the lifestyle disruption following the surgery.

Developing Physiologic Models for Emergency Medical Procedures Under Microgravity

Several technological enhancements have been made to METI’s commercial Emergency Care Simulator (ECS) with regard to how microgravity affects human physiology. The ECS uses both a softwareonly lung simulation, and an integrated mannequin lung that uses a physical lung bag for creating chest excursions, and a digital simulation of lung mechanics and gas exchange. METI’s patient simulators incorporate models of human physiology that simulate lung and chest wall mechanics, as well as pulmonary gas exchange.

Lithium Batteries for Medical Applications

Recent advances in lithium technology have increased the variety of commercially available batteries. The element lithium possesses fundamental properties that make it ideal for use as the anode in both primary and rechargeable batteries. Vendors have paired the popular lithium anode with a variety of cathode and electrolyte materials, resulting in the wide choice of different chemistries available today. This article discusses the types of primary lithium batteries commonly used for medical applications and introduces a new type based on recent innovations in materials and manufacturing processes. Information about the basic properties, advantages, and disadvantages are provided for each battery type.
