Future Robots to Take Blood Samples, Insert Catheters

A US research team has created a tabletop device that combines a robot, artificial intelligence and near-infrared and ultrasound imaging to draw blood or insert catheters to deliver fluids and drugs.

The findings of the research conducted by scientists at the Rutgers University, suggest that autonomous systems like the image-guided robotic device could outperform people on some complex medical tasks.

The study, which was published in the journal Nature Machine Intelligence, showed that medical robots could reduce injuries and improve the efficiency and outcomes of procedures, as well as carry out tasks with minimal supervision when human resources are limited, reported AFP.

"Using volunteers, models and animals, our team showed that the device can accurately pinpoint blood vessels, improving success rates and procedure times compared with expert health care professionals, especially with difficult to access blood vessels," said senior author Martin L. Yarmush, professor of Biomedical Engineering in the Rutgers University.

However, the study also found that failures occur in an estimated 20 percent of procedures, and difficulties increase in people with small, twisted, rolling or collapsed blood vessels, which are common in pediatric, elderly, chronically ill and trauma patients.

Next steps include more research on the device in a broader range of people, including those with normal and difficult blood vessels to access.

"Not only can the device be used for patients, but it can also be modified to draw blood in rodents, a procedure which is extremely important for drug testing in animals in the pharmaceutical and biotech industries," Yarmush said.

At Croatia’s Dugi Otok island in the Adriatic Sea, scientists, demanding action to protect environmentally important meadows of seagrass, have been on a diving mission to assess the damage inflicted by human activity.

Named after Poseidon, the ancient Greek god of the sea, Posidonia oceanica, commonly known as Mediterranean tapeweed, provides food and shelter for fish, protects coasts from erosion, purifies sea water and can play a vital role in helping to tackle global warming.

A meadow of Posidonia can annually soak up to 15 times more carbon dioxide than a similar sized piece of the Amazon rainforest, scientific research has found.

But the scientists say much more needs to be done to protect it from tourist anchoring and from trawlers dragging fishing nets in the waters of the Adriatic Sea off Dugi Otok and the surrounding Kornati archipelago national park.

They have urged tougher regulations and fines for anyone breaching them.

Dominik Mihaljevic, a biologist at the national park, said the park had begun to install anchorages that would not harm the seagrass.

"Our ultimate goal is to completely prohibit anchoring at the 19 anchorage locations that are currently in use," Reuters quoted him as saying.

Matea Spika, a senior associate at Croatia’s Sunce environmental protection association, told Reuters Mediterranean Posidonia, endemic to the Mediterranean Sea, had declined by 30% in the last 30-to-40 years.

Apart from the issue of anchors and fishing nets, she said chemicals, excess nutrients from farms and cities, warmer waters due to climate change, and invasive species had caused further damage.

New ports and artificial beaches have also blocked sunlight essential for Posidonia’s growth.
