FDA Authorizes Aletta, a Robot That Draws Blood
The FDA has approved a robot called Aletta to help draw blood from adults.
It is meant to be used in outpatient medical settings.
A trained phlebotomist must start each session and watch for problems.
The robot helps the patient place their arm correctly.
It uses light and ultrasound to find a vein and avoid arteries.
If it cannot find a safe vein, it will not try to draw blood.
The robot can prepare the skin, insert and remove the needle, fill tubes, and apply a bandage.
It stops if the patient moves too much or its sensors detect danger.
Tests found that it worked about as well as, or better than, trained human phlebotomists.
The U.S. Food and Drug Administration authorized Aletta, the first standalone robotic device designed to draw blood without operator intervention.
Aletta is approved for adults in outpatient settings under the supervision of a trained phlebotomist.
One phlebotomist can oversee up to three Aletta devices, potentially helping address a shortage of trained blood-draw workers.
The device uses near-infrared light and Doppler ultrasound to identify suitable veins and automatically performs the blood draw.
Clinical data showed success rates comparable to or better than trained phlebotomists, with uncommon and mild device-related adverse events.
