This invention proposes an intelligent labor management method and system that integrates LP (labor delivery) detection and multi-parameter monitoring. It belongs to the interdisciplinary fields of smart obstetrics, multimodal physiological monitoring, and human factors engineering. The method includes: dividing the labor process of primiparous women into multimodal monitoring areas, generating core obstetric parameter monitoring areas, and collecting psychological stress monitoring data via millimeter-wave radar and continuously monitoring the fetal biochemical environment via amniotic fluid biochemical probes; deploying the LP labor detection system, non-contact psychological sensors, and amniotic fluid biochemical probes based on these areas to construct an intelligent monitoring layout network; by integrating LP labor detection and multi-parameter monitoring, the overall efficiency of labor management is significantly improved: it achieves accurate monitoring of traditional parameters such as cervical dilation and fetal heart rate, and expands the holistic perception of key dimensions such as maternal psychological stress and amniotic fluid biochemical environment, greatly improving the completeness and real-time performance of labor monitoring.

A portable system for determining dilation of a cervical opening is disclosed. The system includes a probe portion configured for insertion into a vaginal canal, at least one illumination source configured to emit patterned light into a field of view, and an image sensor configured to capture image data including the patterned light as reflected from tissue within the vaginal canal. A processor receives the image data and analyzes spatial characteristics of the patterned light to determine information corresponding to dilation of the cervical opening. In certain embodiments, the processor determines depth information based on geometric relationships between the illumination source and the image sensor and calculates dilation based on the determined spatial information. The system may further include a display and / or a communication module for presenting the dilation measurement and a graphical representation to a user.

A portable system to be inserted within the birth canal for measuring dilation of a cervical region is disclosed. The system comprises a housing having a first portion sized to conform to a user's hand thereby defining a handle and a second portion sized to be inserted into the birth canal. The system includes two structured light sources configured to project a pattern onto the cervical region, a sensor, a trigger interface, a power source, and the processor configured for capturing image sensor data. The processor is configured for receiving image data from the sensor, processing the image sensor data, calculating a measurement of the dilation of the cervical region, and transmitting the data. The processor will transmit the data onto the display, presenting the measurement of dilation as well as a visual representation of the measurement.

This design is related to measuring dilation and effacement during labor and cervical stimulation. To assess the progress of labor, midwives and obstetricians measure the length and opening of the cervix using their two fingers (index and middle fingers), both experimentally and mentally. The goal of this design is to eliminate manual intervention and ensure accuracy and ease in measuring, opening, and massaging the cervix. This design is a graduated instrument with small balls with the ability to adjust the size through an air pump located in the head of the instrument that helps to open and massage the cervix. In this instrument, calculations can be easily done through trigonometric relationships. This device has the ability to store and send information.

This invention proposes a method and system for real-time monitoring and assessment of cervical dilation based on the LP labor monitoring system. It belongs to the interdisciplinary technical fields of intelligent obstetric monitoring, biomedical signal processing, and clinical decision support. The method includes: deploying an FBG-BIS flexible patch at the cervix of the parturient woman to directly collect cervical deformation micro-strain signals, generating raw cervical dilation data; simultaneously collecting uterine contraction pressure signals and fetal heart rate signals, generating raw uterine contraction data and raw fetal heart rate data; performing ternary time-series alignment processing on the raw cervical dilation data, raw uterine contraction data, and raw fetal heart rate data using a dynamic time warping algorithm, generating aligned cervical dilation data, uterine contraction data, and fetal heart rate data; and directly measuring cervical dilation using the FBG-BIS flexible patch, improving the accuracy and comprehensiveness of cervical dilation data acquisition and more realistically reflecting the labor process.

The invention relates to a cervical dilation device and method for the obstetrics and gynecology department. The cervical dilation device comprises a shell, a separation shell clamped to one side of the shell, an inner core arranged in the shell, a guide part arranged in the separation shell and an empty cylinder. The mounting bracket is detachably connected to the other side of the shell; the at least one group of clamping assemblies are arranged in the mounting bracket and are used for clamping and fixing the empty cylinder; the injection mechanism is connected in the mounting bracket in a sliding manner and is used for pushing liquid in the empty cylinder to be injected into the inner core or extracted from the inner core through the mounting bracket; by means of the innovative clutch type transmission design, when the device needs to be withdrawn, an operator only needs to directly, rapidly and axially pull the injection column, the piston can be driven to rapidly pump liquid in the inner core back to the empty cylinder, the inner core is rapidly shrunk, traditional slow reverse rotation operation is abandoned in the process, time consumed in the withdrawing stage is reduced to the minimum, and the device is convenient to use. Therefore, the whole operation time is effectively shortened, the turnover efficiency of an operating room is improved, and related risks possibly brought by instrument retention are reduced.

The present application belongs to the technical field of part of human body measurement, and particularly relates to a detector for measuring before delivery, which comprises a detection component and a measuring component detachably connected with the detection component, the detection component comprises a first detection piece and a second detection piece, the first detection piece comprises a first finger cuff and a catheter connected to a lower end of one side of the first finger cuff, and an upper end of the first finger cuff is provided with a wire hole communicated with the catheter, the detector is provided in a split mode, and a relatively accurate reading can be obtained on the measuring component through body measurement by the detection component, so that accurate measurement of cervical dilation helps doctors to accurately judge the delivery process, in addition, since only the detection component of the whole detector contacts the puerpera, the structure of the detection component is relatively simple, and the manufacturing cost is relatively low, therefore, the detection component can be used as a disposable product, so that the puerpera can be provided with a relatively safe detection service at a relatively low use cost.

This utility model relates to the field of medical device technology and discloses a cervical dilation balloon catheter, including a catheter body. An outer inflatable balloon is fixedly sleeved on the outer wall of the front end of the catheter body. A connecting tube is fixedly connected to the outer surface of the rear end of the catheter body. A first injection port, an inflation port, and a second injection port are fixedly connected to the outer surface of the rear end of the connecting tube.
