A Single-Center, Randomized, Crossover, Prospective, Open-Label, Non-Inferiority Confirmatory Clinical Trial to Evaluate the Safety and Efficacy of an AI- and Ultrasound-Based Medical Device That Assists Venipuncture, Compared With Manual Venipuncture
Purpose : This study aims to confirm the safety and efficacy of AIIV L2, an artificial intelligence- and ultrasound-based medical device that assists venipuncture, by comparing venipuncture performed using AIIV L2 with manual venipuncture. Study Design : This is a single-center, randomized, crossover, prospective, open-label, non-inferiority confirmatory clinical trial. Methods : Each participant will undergo venipuncture on both arms: one arm using AIIV L2 and the other arm using manual venipuncture, according to randomized allocation. After venipuncture is performed on both arms, outcomes including venipuncture success rate, procedure time, pain, and hemolysis will be evaluated. All venipuncture procedures will be performed by the same operator. Vital signs and adverse events will be monitored before and after the procedure. \- Primary Efficacy Endpoint Venipuncture success rate: Comparison of the success rate of venipuncture on the first attempt between AI-assisted venipuncture and manual venipuncture. \- Secondary Efficacy Endpoints Procedure time: Time from needle insertion to completion of venipuncture. Hemolysis rate: Presence of hemolysis in collected samples, determined according to laboratory criteria. Pain score (NRS): Numeric Rating Scale (0-10) reported by participants after each venipuncture method. Within-subject pain comparison: Comparison of pain scores between AI-assisted and manual venipuncture within the same participant. Acceptability: Participant satisfaction and preference regarding AI-assisted venipuncture, assessed using a structured questionnaire.
• Male or female adults aged 19 years or older at the time of study enrollment.
• Subjects who are able to undergo venipuncture in the antecubital area of both arms, without restriction of elbow joint movement, and who can maintain the arm in a stable extended position during venipuncture.
• Subjects who have received a full explanation of the clinical trial, fully understand the contents, voluntarily decide to participate, and provide written informed consent prior to screening procedures.
