RESPeRATE aims to let users breathe their way to lower blood pressure

People suffering from hypertension (also known as high blood pressure) are typically advised to switch to a healthier diet, get more exercise and lose weight, plus they are often put on a combination of several medications. As of today, UK residents are now also able to get a prescription for what is definitely a different type of treatment – a system known as RESPeRATE. It monitors the patient’s breathing and uses sound to guide them into taking longer, slower breaths, thus relaxing their bodies. According to its makers, multiple clinical trials have shown that it causes significant, lasting reductions in blood pressure.Read More

Scanadu developing a real-life medical tricorder

The future technology depicted in the various Star Trek TV series and films certainly holds a lot of appeal for many of us – who wouldn’t want to teleport to Hawaii, live out their fantasies on a holodeck, or enjoy some instant gourmet chow straight out of a replicator? It looks like the Star Trek item that we’re the closest to seeing become a reality, however, is the medical tricorder. This May, the X-PRIZE Foundation proposed a US$10 million Tricorder X-PRIZE, with the intention of encouraging the production of consumer devices that can assess a person’s state of health. The first potential contestant, which already has a tricorder in the works, is a tech start-up by the name of Scanadu.Read More

iHealth helps manage your blood pressure and weight on your iPhone

For many people, a key part of their personal health management routine involves monitoring their blood pressure and weight. Frequently going to get one’s blood pressure measured at a pharmacy or clinic, however, can be a hassle. Well, to paraphrase an advertising slogan, “there’s an app for that” – along with a device. The iHealth Blood Pressure Monitoring System for iPhone, iPod touch and iPad consists of a blood pressure arm cuff wired to a portable dock, along with the free iHealth app, which users run on their chosen iDevice to keep track of their systolic and diastolic blood pressure and heart rate. They will also soon be able to throw their weight data into the mix, with the iHealth Scale.Read More

Ultrasound said to offer better technique for measuring blood pressure

Not only is the old inflatable-cuff-around-the-arm an uncomfortable way of having one's blood pressure measured, but it turns out that it doesn't always provide enough information, either. If a physician wishes to check for vascular diseases such as atherosclerosis, thrombosis or aneurysms, for instance, they're going to want to know how the blood is flowing in areas besides the patient's arm. Because the cuff works by temporarily stopping the blood flow, however, it's not going to work too well on a patient's neck or torso. Fortunately, scientists from The Netherlands' Eindhoven University of Technology (TU/e) have discovered that ultrasound can be used instead, and that it provides more details. Read More

New system offers more accurate blood pressure measurements

Traditionally, blood pressure is measured using the familiar inflatable cuff and stethoscope on the upper arm. While this method has sufficed for over a century, some people maintain that it is inaccurate – blood pressure in the arm is reportedly higher than at the heart, and not by a consistent, easily compensated-for amount. Because high blood pressure can cause the most damage at the heart and in the nearby brain, it would make sense to monitor it at the heart, too. That's just what a new device designed at the University of Leicester does ... in a roundabout way.Read More

Monitor blood pressure while scrolling and clicking with the MDMouse

Monitoring blood pressure at home is recommended by the American Heart Association for the estimated 74.5 million American adults suffering from hypertension. CalHealth has created a blood pressure monitor that's housed in a computer mouse. After a user pushes a finger into the cuff monitor, the device sends readings to software on a PC for analysis, or to send on to doctors via email.Read More

MIT developing webcam-based health monitoring mirror

Sitting in front of your computer could soon be the fastest way to receive a medical check up, replacing visits to the local doctor. Massachusetts Institute of Technology student Ming-Zher Poh has created a pulse-monitoring system that works on a low-cost, low-resolution webcam. A version of the system built into a mirror has been developed which displays pulse rate at the bottom in real-time, and work is underway to add respiration and blood-oxygen level monitoring using the same technique.Read More

Blue Watchdog turns your mobile phone into an all-purpose anti-theft device

One of the greatest threats to our personal welfare in the digital age is the theft of our key life-enhancing devices – while a stolen bag, camera, or wallet can be replaced at significant heartache and expense, a laptop might contain the keys to your banks accounts, employer's intranet, or your identity. Now there’s an ingenious anti-theft device which sets a user-defined protection radius of between one and 30 meters around the mobile phone in your pocket using Bluetooth functionality. The credit-card-sized, EUR60 Secu4 Blue Watchdog is so useful it just might generate killer app adoption levels for protecting your valuables, luggage, and perhaps even your children when you’re on the go. Check out our video of the new product.Read More

Researchers unveil prototype implantable artificial kidney to replace dialysis

End-stage renal disease, or chronic kidney failure, affects more than 500,000 people per year in the U.S. alone, and currently is only fully treated with a kidney transplant. That number has been rising between five to seven percent per year and with just 17,000 donated kidneys available for transplant last year the waiting list currently exceeds 85,000, according to the Organ Procurement and Transplant Network. Those who can’t secure a kidney for transplant are left reliant on kidney dialysis. An expensive and time consuming process that typically requires three sessions per week, for three to five hours per session, in which blood is pumped through an external circuit for filtration. In a development that could one day eliminate the need for dialysis, researchers have unveiled a prototype model of the first implantable artificial kidney.Read More

Sugar-powered biofuel cell to power artificial organs and medical implants

The miniaturization of electrical sensors coupled with the development of flexible silicon technology paves the way for a wide variety of medical sensors that can be implanted into the human body. One of the major obstacles facing the development of such devices, not to mention artificial organs, is how they are powered. Currently devices need to be constantly recharged via an external power source or, as is the case with battery-powered pacemakers, replaced altogether. Now a team of French researchers has implanted a new type of biofuel cell into rats that overcomes these problems by generating electricity from a potentially limitless source - sugar in the rat’s bodies.Read More
