FDA approves robot that can find your vein, insert a needle, and draw blood without human help

TechSpot • August 20, 2026 • business

Key Points:

The FDA has approved Aletta, a robotic device capable of drawing blood from patients' arms without human assistance, aiming to address the shortage of trained phlebotomists in the US.
Aletta uses near-infrared light and Doppler ultrasound to locate veins, applies a tourniquet, inserts the needle, and completes the blood draw, while a trained supervisor oversees the process and verifies tube collection.
The device includes safety features such as automatic needle detachment if the patient moves excessively and sensors that pause the procedure and alert supervisors if unsafe conditions arise.
Clinical data indicate Aletta's blood draw success rates are comparable to or better than those of trained phlebotomists, potentially improving efficiency in medical settings.
Despite FDA approval, the rollout of Aletta in healthcare facilities may take time, and some patients may remain uncomfortable with a robot performing blood draws.
