“The U.S. Food and Drug Administration today authorized the Aletta, the first standalone robotic device that can draw blood from a patient’s arm without hands-on operator intervention. The device is authorized for use in adults in outpatient settings and must be operated under the oversight of a supervisor trained in phlebotomy. One phlebotomist can oversee up to three Aletta devices at the same time, which may help address the current phlebotomist shortage in the U.S…
The Aletta autonomously handles each step of the blood draw, while a trained phlebotomist initiates each session and remains available to respond to any issues throughout. The device guides the patient to position their arm, after which the patient or supervisor presses a button to start the blood draw. The Aletta then uses near-infrared light and Doppler ultrasound to locate a suitable vein and tell it apart from arteries. If no appropriate vein is found, the device will not attempt the procedure.
Once a vein is identified, the Aletta proceeds through the remaining steps on its own: applying a tourniquet, preparing the skin, inserting and disposing of the needle, changing collection tubes and placing a bandage.”
