A few years ago, we heard that a research team was developing a robot dedicated to blood sampling. Although the machine was tested on an artificial arm at the time, we had high hopes for the future of the technology. The good news is that Rutgers University has just announced that its blood-picking robot has successfully completed testing in real people. Of the 31 volunteers, 97% of the intravenous blood samples were successfully taken and the overall success rate was 87%.

The new prototype, built by an engineering team at Rutgers University in New Jersey, can be placed on a patient’s arm and used ultrasound imaging technology to locate a good vein.
The machine then needles the needle into the vein, takes a blood sample, and transfers it to a centrifuge-enabled blood analyzer.
In fact, the team tested the latter as early as 2018 in the artificial arm trial. In a recent experiment, however, the team invited 31 volunteers.
Of these, 25 participants had a 97% success rate in intravenous blood collection and an overall success rate of 87%. Rutgers university points out that these figures meet or exceed clinical standards.
According to previous studies, clinicians had a venous needle success rate of only 27% in a group of patients with difficulty developing venous development.
In the hard-to-reach patient population, the figure is 40%. There is also a 60% success rate in the patient group who are thin.
As the technology matures, blood-picking robots can also be used for intravenous catheterization, dialysis and arterial line placement.
In addition, robots can effectively avoid complications that can result from repeated attempts to make them, such as venous inflammation, blood clots, and infections.
“These machines help clinicians quickly, safely and reliably obtain blood samples, preventing unnecessary complications and pain from multiple needles,” said Study Co., D.C. Lead Dr. Josh Leipheimer.
Details of the study have been published this week in the journal Technology. Originally published as:
