  1. 16. Development of patient-specific fetal head phantom for experimental evaluation of vacuum assisted delivery

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Maria Pop; [2021]
    Keywords : Vacuum assisted delivery; Vacuum extractor device; Traction force; Vacuum pressure; Fetal head phantom; Ultrasound imaging; Sonomicrometry;

    Abstract : Vacuum assisted delivery (VAD) is a common procedure used in the final stage of labor in the situation of a difficult natural delivery. Since the only biomechanical studies concerning the clinical safe traction force were conducted during 70s using simplified models to mimic the fetal head, concerns remain regarding the side effects of this medical intervention when applying high levels of traction forces.
