DESIGN OF A WEARABLE DEVICE FOR MEASURING UTERINE FUNDAL HEIGHT IN PREGNANT WOMEN

Abstract

Background: Accurate measurement of uterine fundal height (FU) is crucial for monitoring fetal development and identifying potential pregnancy complications. Traditional methods for measuring FU can be inconvenient and less precise with variations in provider competencies, which complicates effective antenatal care.

Objectives: This study presents the design of an innovative wearable device intended to facilitate midwives in measuring FU more easily and accurately. The device integrates the TF Mini S LiDAR sensor, inertial measurement units (IMU), and pressure sensors to offer continuous, real-time measurements of uterine fundal height.

Method: A mixed methods approach is utilized, combining quantitative and qualitative analyses. Quantitatively, the device’s measurements are calibrated and validated against standard FU measurement techniques, achieving accuracies of X%, Y%, and Z% for the TF Mini S LiDAR sensor, IMU, and pressure sensors, respectively. Qualitatively, feedback from midwives through surveys and interviews assesses the device’s usability and clinical effectiveness.

Results: The wearable device demonstrates high accuracy in measuring FU, with results closely matching those of traditional methods, achieving a correlation coefficient of R. Feedback from midwives highlights that the device simplifies the measurement process and enhances accuracy, proving to be a valuable tool for antenatal care.

Conclusion: The wearable device designed for measuring FU provides midwives with a practical and precise tool for continuous monitoring. By integrating advanced sensors, the device improves both the accuracy and ease of FU measurement, potentially advancing antenatal care and enhancing patient outcomes. Future research will focus on further refining the technology and exploring its broader applications in clinical settings.
