Thermal Imaging Helps To Study Non-Contact Electromagnetic Induction Heating For Eradicating Bacteria And Yeasts From Metal Implants
Thermal Imaging Helps To Study Non-Contact Electromagnetic Induction Heating For Eradicating Bacteria And Yeasts From Metal Implants Infections in joint replacement surgery are a major factor in the failure of the used metal implants, especially when more strains of bacteria become resistant to antibiotics. Heating up the joints would eliminate bacteria and yeast, but the concern is whether or not this can be done in a non-invasive fashion.  Continue Reading...
LIST Researchers Use FLIR Cameras To Study The Electrocaloric Effect
LIST Researchers Use FLIR Cameras To Study The Electrocaloric Effect Refrigerant devices typically use fluid coolants turned into gases to cool things down. These gases, however, may become harmful to the environment, so research is being done on the use of solid materials as a substitute to cool down food, beverages, medicine, and even electronic devices. Researchers at the Luxembourg Institute of Science and Technology (LIST) are making use of FLIR’s thermal imaging cameras to study the subject.  Continue Reading...
Toxicological Risk Assessment Of Medical Devices: An Overview The FDA requires toxicological risk assessments performed for most medical device submissions founded on the notion that if all of the constituents of a medical device are known, then the safety of the device can be assessed based on the toxicology of those constituents.  Continue Reading...
FLIR Thermal Cameras Help To Reduce The Invasiveness Of Cochlear Implant Surgery
FLIR Thermal Cameras Help To Reduce The Invasiveness Of Cochlear Implant Surgery The surgical placement of Cochlear hearing implants behind the human ear requires a highly trained surgeon, and can result in facial nerve damage, meningitis, tinnitus, infections, cerebrospinal fluid leakage, and potentially more.  Continue Reading...
From “Guess” To “Best”: How Infrared Cameras  Are Increasing Accuracy And Insight In Product Testing
From “Guess” To “Best”: How Infrared Cameras Are Increasing Accuracy And Insight In Product Testing This article explores how infrared (IR) cameras deliver a major data-gathering advantage over legacy approaches to temperature measurement, an advantage that can prevent costly product failures and safety hazards, providing an immediate and ongoing return on investment.  Continue Reading...
Thermal Imaging Cameras Allow Machines To Read Human Emotions
Thermal Imaging Cameras Allow Machines To Read Human Emotions Scientists are researching how machines can understand human emotions through thermal imaging. In order for Artificial Agents (AAs) to set up contingent emotional and psychophysiological interaction with humans, the automatic nervous system (ANS) must be monitored and translated efficiently.   Continue Reading...
Documentation In Device Studies – Proving Patient Protection I can still recall the voice of my thesis advisor in graduate school saying in regards to our laboratory research, “If it’s not documented, it’s not done!”. Since those grad school days, I’ve had a love-hate relationship with documentation. By Brandy Chittester, IMARC Research, Inc.   Continue Reading...
Tribology And Testing Of Orthopedic Implants The orthopedic implant industry is in a continual state of development, witnessing an explosion of novel materials, designs, and applications. This process is, however, often laced with challenges and articulating joints can present the greatest number of these. By Aia Malik, Lucideon, and Chris Pickles, Ph.D.  Continue Reading...

    Medical Device Design & Manufacturing Challenges: 2017 And Beyond

    Medical device manufacturers and designers must overcome various challenges to succeed in an expanding global marketplace, challenged along the way by aspects of design, research, validation, and bringing their devices to a competitive market in a cost-effective manner.

  • Incorporating Stress Into User Testing
    Incorporating Stress Into User Testing

    How do you design a usability test that mimics the panicked, stressful situation that a user may be in when he or she is using your medical device in the real world?

  • The Case For Formative Human Factors Testing
    The Case For Formative Human Factors Testing

    Because the validation test is required human factors testing, it can be tempting to skip over preliminary human factors activities during the development process. However, this approach is problematic from both a device usability and a safety standpoint.

  • How To Use Reliability-Based Life Testing Sampling For Process Validation
    How To Use Reliability-Based Life Testing Sampling For Process Validation

    The first article in this series, Risk-Based Approaches To Establishing Sample Sizes For Process Validation (June 2016) provided and established the relationship between risk and sample size. This article will demonstrate the use of reliability-based life testing for process validation.

  • Evaluating The Increase And Distribution Of Temperature During Dental Drilling Using A Thermal Imaging Camera
    Evaluating The Increase And Distribution Of Temperature During Dental Drilling Using A Thermal Imaging Camera

    In some cases, the rotary speeds from dental drills can cause dangerously high temperatures, which can permanently damage bone tissue as they increase the denaturation of hard tissue proteins. This article discusses research on drilling techniques in a lab setting. 

  • How To Know You’ve Passed Validation Testing (And What To Do If You Haven’t)
    How To Know You’ve Passed Validation Testing (And What To Do If You Haven’t)

    When studies are successful, human factors (HF) validation can be as straightforward as checking off the boxes on a study protocol. If all the pieces of testing don’t come together as planned, however, HF validation can be a complicated endeavor. At the recent HFES Symposium on Human Factors and Ergonomics in Health Care, we shared our thoughts on how to know whether or not you’ve cleared that last hurdle.

  • Reduce Risk With Exploratory Medical Device Software Testing
    Reduce Risk With Exploratory Medical Device Software Testing

    More and more medical devices have some sort of software component to them. The teams responsible for testing this software often rely on scripted testing, both manual and automated, to decrease the risk of defects in a product under development. The problem with this approach is that scripted testing is not meant to identify error conditions in scenarios that significantly deviate from the design or requirements, even if a comprehensive risk management plan is followed. To find these hidden or divergent risks, you need to go off script, and that’s where adding exploratory testing can help.
