  • Artificial and portable Kidneys

    Kidneys perform an essential function in the body of removing the waste – salts, many metabolites and also many other waste substances. However, in many patients this kidney is damaged and there are only two possibilities for these patients: 1.Kidney transplantation – very difficult to do, very expensive and very difficult to find a donor…

  • Personal monitoring – Basis watch or band

    There are many fitness monitors out there from Nike’s fuel band to Fit Bit. They all promise monitoring of activity in some form or another but none are very comprehensive.One company, promises better watches and sensors – Basis. Their sensors are equipped with not just accelerometer sensors but they also capture skin sweat secretion, heart…

  • Virtual Reality and Schizophrenia

    It is often difficult for caregivers of Schizophrenia patients to understand and fully appreciate the experience of schizophrenia patients. If you have never experienced the symptoms, then it is difficult to feel what the patient is feeling. I was sent a link to the website that has been doing just that… Dr James Cook at…

  • Saving lives with mats that absorb liquid – cool medical device!

    Innovations that save lives sometimes take a $1 Billion or more and many researchers while some are simple and effective. The innovation that has already saved many lives is a birth mat. Birthing process is dangerous and is a risky, messy and tedious affair to say the least. Many lives are lost in developing countries…

  • Brain computer interface

    Nicolelis’s lab has been working on the brain machine interface. The interface will obviously help many paraplegics but could be a boost for many neurological disorders. The lab has produced monkeys that can control objects using just their brains without any motor function. Recently, they created a mouse that though could not see infrared light…

  • Scattering of Light and Diagnostic testing

    Development of any one field requires corresponding development in other fields. Sometimes the fields are so unrelated that it seems amazing that one field would have influenced the other. But consider the link between diagnostic tests and the observation that the sky is blue. This is not about “blue sky thinking” but rather a direct…

  • Diagnostic tests – the gold standard

    The gold standard for almost all the paper based diagnostic tests is the home pregnancy test called Clear Blue. What is forgotten is that this test was created in 1985 by a company called Unipath and this went on to become the most often used test that became a standard by which most diagnostic tests…

  • Medical software development – Finite state machines

    Food and Drug Administration (FDA) regulates significant portion of medically relevant devices and drugs but it is probably not as well known that they also regulate the software that is used to power many of the studies. There are significant guidelines from FDA that are used for manufacturers of software that regulate medical devices. The…

  • Medical Devices industry standard – Global Location numbers (GLN)

    Medical Devices industry standard – Global Location numbers (GLN)

    Computers are good with numbers and can form precise calculations. They remember perfectly and can manage big lists of numbers. What they are not good at is averaging and understanding meaning. So for example, “St Peters Hospital” will be different from “St Peter’s Hospital” if it appears in medical records. And, nowadays since most of…

  • Measuring heartbeat from 3 feet away – Electric potential sensors

    Measuring heartbeat from 3 feet away – Electric potential sensors

    Robert Prance’s team at University of Sussex in UK have discovered and created a unique electric potential sensor that is a perfect voltmeter and can measure a heart beat from nearly 3 feet away. It measures the spatial electrical potential or field. This has been difficult since the electrometers that measure voltage, electric charge or…
