Environmental Awareness Leads to PVC-Free Assemblies

Totally PVC-free products provide an environmentally safer alternative. Over the last several years, the medical industry has become more aware of the toxic side effects of polyvinyl chloride (PVC). The American Public Health Association passed a resolution in November 2011 urging hospitals, schools, and nursing homes to reduce the amount of PVC they use.

Prosthetic Foot Uses Unique Aerospace Material

A new space-age material creates a prosthetic foot that’s built to last. Formerly used only in the aerospace arena, Flexeon is a radical departure from the rigid carbon fiber materials found in most prosthetic feet. It’s a specially- formulated reinforced fiberglass material that is nearly indestructible, extremely flexible, and available exclusively on Ability Dynamic prosthetic devices, such as the RUSH™ foot. Flexeon underwent thorough and extensive testing for flexibility, material strength, and durability in prosthetic labs, as well as on patients aged 21 to 69 in clinical trials. The results of these tests and trials revealed that this high-tech material is three times more flexible than carbon and much more durable than current standard carbon fiber products.

Instantly Capture, Edit, and Store Medical Images via Online Applications

Online tool allows user to conveniently capture and manage images from medical devices. A new image capture software development kit (SDK), called the Dynamic Web TWAIN, allows the simplified creation of an online tool to manage images of patient records. It enables image application providers to deliver a method to capture images from medical devices, such as intraoral cameras and digital x-ray equipment, and then send the medical images to a central web server. Such medical image captures can be sent alongside a patient’s identification, results data, applied treatments, next visit schedules, and more. An SDK allows implementation within popular Internet browsers, including Internet Explorer, Chrome, Firefox, Safari, or Opera. (See Figure 1)

New Blood Pressure Connectors Prevent Misconnects

Fittings make quick connections easier and safer, even in low-light situations. Healthcare professionals use medical devices in a variety of settings and situations from urgent to routine. In an emergency, any sort of confusion, hindrance, or hesitation concerning the most minor detail or part of a device can mean a matter of life or death. As a result, there is a constant battle among medical device manufacturers to develop products with superior ergonomics, risk-free designs, and the ability to meet extensive technical requirements—all while maintaining a reasonable profit margin. In response to these concerns, Value Plastics has developed a new line of quick connect fittings. Their BPL Series of tubing connectors incorporates a number of features that are not only aimed at meeting engineers’ needs but also designed to ease users’ stress and frustration that can arise from use in critical situations.

Transferrable Sensor Tattoo Measures Metabolic Stress

Smiley sensor works like a temporary tattoo to detect disease. A medical sensor, that adheres to the skin like a temporary tattoo could make it easier for doctors to detect metabolic problems in patients as well as help coaches to fine-tune athletes’ training routines, say researchers at the Department of Physical & Environ mental Sciences at the University of Toronto, Scarborough, Canada (UTSC). The entire sensor was designed as a thin, flexible package shaped like a smiley face.

Extreme Ionizing-Radiation-Resistant Bacterium

Deinococcus phoenicis sp. nov. can be used as an indicator for sterilization processes in food, aerospace, medical, and pharmaceutical applications. There is a growing concern that desiccation and extreme radiation-resistant, non-spore-forming microorganisms associated with spacecraft surfaces can withstand space environmental conditions and subsequent proliferation on another solar body. Such forward contamination would jeopardize future life detection or sample return technologies. The prime focus of NASA’s planetary protection efforts is the development of strategies for inactivating resistance-bearing microorganisms. Eradi cation techniques can be designed to target resistance-conferring microbial populations by first identifying and understanding their physiologic and biochemical capabilities that confers its elevated tolerance (as is being studied in Deinococcus phoenicis, as a result of this description). Furthermore, hospitals, food, and government agencies frequently use biological indicators to ensure the efficacy of a wide range of radiation-based sterilization processes. Due to their resistance to a variety of perturbations, the non-spore forming D. phoenicis may be a more appropriate biological indicator than those currently in use.

Porcupine Quills Aid Device Design

Understanding the mechanisms behind quill penetration and extraction could help engineers design better medical devices. Once a porcupine’s quill penetrates your skin, it’s very difficult to remove. That’s the inspiration behind research at Massachusetts Institute of Technology and Brigham and Women’s Hospital, Boston, to develop new types of adhesives, needles, and other medical devices.
