Monitoring critical blood levels in real time in the ICU

23.10.2015

EPFL has developed a miniaturized microfluidic device that will allow medical staff to monitor in real time levels of glucose, lactate a.s.o. and react more quickly

No larger than a pack of chewing gum, the prototype developed by EPFL's Integrated Systems Laboratory (LSI) is deceptively simple in appearance. But this little black case with two thin tubes sticking out contains some real miniaturized high-tech wonders.

"We embedded biosensors in it to measure several different substances in the blood or blood serum along with an array of electronics to transmit the results in real time to a tablet via Bluetooth," said Sandro Carrara, an LSI scientist.

Capable of being connected to a drainage tube that's already in place, the new system is much less invasive than the many monitoring devices that it's designed to replace.

It keeps constant tabs on the blood levels of five substances: metabolites (glucose, lactate and bilirubin) and ions (calcium and potassium), all of which indicate changes in the condition of intensive-care patients.

"Nowadays, several of these levels are measured periodically. But in some cases, any change in level calls for an immediate response, something that is not possible with the existing systems," said Dr. Carrara.

Building on this principle, up to 40 molecules could be monitored in real time. This advance will drastically reduce the number of machines cluttered around patients - an obvious practical advantage for the medical staff, not to mention the psychological boon for loved ones.

The prototype, which was made with a 3D printer, has been successfully tested on rodents. Discussions are now under way for tests to be carried out at the University Hospital of Lausanne (CHUV). And a number of manufacturers have already expressed serious interest in developing this device. "We could hit the market in two to three years," said Dr. Carrara.

This progress towards more precise and effective medicine was achieved under the Nano-Tera initiative, which is financed by the Swiss government. The device was unveiled on October 22nd in Atlanta at the 2015 BioCAS Conference.

Im Focus: BAM@Hannover Messe: innovative 3D printing method for space flight

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.

Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...

Im Focus: Molecules Brilliantly Illuminated

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.

Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
