Solution Overview
Problem
Current labor detection methods are inadequate for accurately identifying the onset of labor, particularly in cases of false labor, silent labor, and amniotic fluid leakage, leading to potential complications and increased risk of maternal and fetal deaths due to delayed medical intervention.
Innovation Solution
A remote microelectromechanical labor detection system using MEMS devices implanted on the cervix to monitor cervical dilation and pH status, transmitting data wirelessly to a network monitor for real-time remote monitoring, enabling continuous and rapid measurement of cervical changes during pregnancy and labor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If standard cervical measurement procedures are used during labor, then medical personnel can monitor cervical dilation status, but it requires frequent manual insertion of fingers or instruments into the vagina which causes patient discomfort and taxes limited medical personnel resources
Solution Approach 1:
The patent replaces manual mechanical cervical measurement (finger insertion) with an automated MEMS sensor system that uses electrical or optical fields to measure cervical dilation distance, eliminating the need for repeated physical examinations and reducing patient discomfort while maintaining measurement precision
Solution Approach 2:
The MEMS sensor system performs self-measurement of cervical dilation continuously without requiring external medical personnel intervention, automatically tracking the distance between cervical landmarks and transmitting data wirelessly, thereby freeing medical personnel from routine monitoring tasks
2Reliability
If patients travel to the hospital for labor detection, then actual labor can be confirmed, but it increases the risk of maternal and fetal deaths due to delayed medical intervention in cases of silent labor or amniotic fluid leakage
Solution Approach 1:
The system performs preliminary continuous monitoring of cervical dilation and pH status before actual labor symptoms manifest, detecting silent labor and membrane rupture early, allowing medical intervention to be prepared in advance rather than waiting for symptoms to develop
Solution Approach 2:
The system provides continuous real-time feedback on cervical dilation progress and pH changes, enabling dynamic monitoring that immediately alerts medical personnel when labor begins or complications occur, eliminating the delay associated with periodic hospital visits
3Productivity
If continuous cervical monitoring is performed using manual methods, then labor progression can be tracked, but it requires constant medical personnel presence which is not feasible with limited resources
Solution Approach 1:
The patent replaces manual mechanical monitoring with an automated electronic MEMS sensor system that continuously measures cervical dilation and transmits data wirelessly, enabling high-frequency monitoring without requiring constant medical personnel presence and reducing overall resource requirements
