At the BioCAS 2015 conference in Atlanta, USA, scientists at the EPFL in Lausanne, Switzerland, demonstrated a unique 3D printed medical device that monitors the level of key blood indicators in real time. This is a miniaturized microfluidic device that uses a range of biosensors that may not have a large package of gums, but allows medical professionals to view the patient's blood sugar, lactic acid and other blood levels.
Despite its small size and common appearance, this 3D printing device combines a variety of basic medical techniques for patient data collection and transmission. “We have embedded biosensors in it to measure many different substances in blood or serum, and to transfer data to the tablet in real time via electronic systems via Bluetooth,†explains Sandro Carrara, a scientist at the EPFL Integrated Systems Laboratory.
It is understood that this 3D printed device can monitor the levels of metabolites (blood sugar, lactic acid and bilirubin) and ions (calcium, potassium) in the blood, which are reflected in the condition of patients undergoing intensive care. Key indicators. Because blood levels can be monitored through the facts of the tool, doctors can act quickly when these blood indicators have just shown to be potentially dangerous. “Before this, several indicators in the middle were measured regularly,†Dr. Carrara explained. “But in some cases, any change in some indicators requires an immediate response, which is not possible with existing systems.â€
EPFL scientists say the device has several advantages over other similar devices. For example, its small size can reduce the patient's sense of uneasiness and make it more comfortable. In addition, it can detect a wide range of substances. It can monitor up to 40 molecules at the same time, enough for medical staff to lose those kinds. A machine that monitors a molecule. This will bring several benefits to the hospital: first, it can be the hospital's savings in purchasing more equipment; it also frees up valuable space; in addition, because there is not a lot of oppressive equipment in front of it. It also helps to calm nervous patients and their families.
The prototype of this 3D printed device has been tested on rodents, and the University of Lausanne (CHUV) has developed an interim plan to test the device on humans. Due to its broad prospects, many manufacturers and investors have expressed interest in it. Dr. Carrara said: "We can put it on the market within two to three years."
The university's research was supported by the Swiss government-funded Nano-Tera program.
