Phantom models for childbirth simulation have become essential tools in the education of healthcare professionals, allowing for safe practice without risks to patients. This article presents the design of a monitoring and control system for the simulation of obstetric maneuvers, with a focus on Leopold maneuvers. The enhancement of the Noelle phantom includes the use of electronic and mechanical components for fetal movement, a graphical interface for monitoring heart rate, blood pressure, oxygen saturation levels, and for controlling the movements of motors that position the fetus in the birth canal, as well as a realistic artificial arm made from synthetic materials. The results indicate that heart rate measurements have an average error of ±0.475 BPM with an accuracy of 0.517 BPM. For blood pressure, there are minimal errors of 0.805 mmHg and values of 0.365 mmHg for systolic and diastolic blood pressure, respectively. Regarding oxygen saturation levels, there is an average error of 0.375%, and a descent rate error of 0.195 cm/h for fetal descent velocity. Additionally, the user interface was evaluated by professionals in the field, demonstrating the system’s effectiveness, fidelity, and reliability, representing a significant advancement in medical training.

摘要

Phantom models for childbirth simulation have become essential tools in the education of healthcare professionals, allowing for safe practice without risks to patients. This article presents the design of a monitoring and control system for the simulation of obstetric maneuvers, with a focus on Leopold maneuvers. The enhancement of the Noelle phantom includes the use of electronic and mechanical components for fetal movement, a graphical interface for monitoring heart rate, blood pressure, oxygen saturation levels, and for controlling the movements of motors that position the fetus in the birth canal, as well as a realistic artificial arm made from synthetic materials. The results indicate that heart rate measurements have an average error of ±0.475 BPM with an accuracy of 0.517 BPM. For blood pressure, there are minimal errors of 0.805 mmHg and values of 0.365 mmHg for systolic and diastolic blood pressure, respectively. Regarding oxygen saturation levels, there is an average error of 0.375%, and a descent rate error of 0.195 cm/h for fetal descent velocity. Additionally, the user interface was evaluated by professionals in the field, demonstrating the system’s effectiveness, fidelity, and reliability, representing a significant advancement in medical training.
