Scientists from Rutgers University in the United States conducted the first clinical testing of a robot that took blood from a vein. He showed efficacy at 87% (31 participants), and in patients with easily accessible veins – at 97% (25 participants).
Ordinary nurses, according to statistics, experience difficulty in taking blood in 27% of patients whose veins are poorly visible. In addition, difficulties arise in 40% of cases with blood sampling in patients with weak palpation of veins and in 60% of cases with malnourished patients.
At the same time, the reintroduction of needles threatens with vein injuries, thrombosis and phlebitis, not to mention an increase in the time for receiving the patient. The total losses from this in the United States alone are estimated at $ 4 billion per year. The procedure is considered the most common in the country – annually blood from a vein is taken from 1.4 billion people.
The robot also works with ultrasound control. It has a built-in centrifuge analyzer module for sample processing. His next version, as the researchers promise, will be able to perform intravenous catheterization, dialysis and other procedures.
The robot can be used in emergency rooms, in the ambulance and in doctors’ offices.
Previously, scientists from the University of Vermont created xenobots – living robots that can move and self-repair. Material was taken from the African clawed frog Xenopus laevis. The project was developed using the Deep Green supercomputer. The supercomputer, taking into account the peculiarities of cells and programmed requirements for robots, for example, the ability to move, has created many options for the forms of future organisms.
