Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge lies in locating wireless fetal monitoring probes in a set area, as they are difficult to find and there is a high risk of data loss due to their wireless nature, making it hard for healthcare professionals to track patients' positions and receive timely monitoring data, especially when patients move outside the hospital's obstetrics and gynecology department.
Innovation Solution
A method and device that utilize wireless base stations to send instructions to probes to detect signal intensities, create signal intensity data tables, and calculate distances to reference points, allowing for the accurate location of probes within a set area, with features like data saving and probe identification to prevent data loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If wireless fetal monitoring probes are used to allow pregnant women to move freely, then patient mobility and comfort are improved, but the probes become difficult to locate and data loss risk increases
Solution Approach 1:
The system continuously receives signal intensity data from probes and provides real-time feedback about probe locations and data transmission status. The data management center monitors signal intensities from multiple base stations and automatically tracks probe positions, ensuring continuous feedback on probe status and enabling immediate detection of data loss risks
Solution Approach 2:
Wireless base stations serve as intermediaries between probes and the data management center. The base stations relay signal intensity data and monitoring information, enabling indirect tracking of probe locations and ensuring continuous data transmission even when probes move freely throughout the hospital
2Area of stationary object
If wireless fetal monitoring probes are used instead of wired probes, then cable management and occupied area are improved, but probe location tracking becomes difficult
Solution Approach 1:
The patent replaces mechanical cable-based positioning with wireless signal-based positioning. Instead of using physical cables to track probe locations, the system uses wireless signal intensity measurements from multiple base stations to calculate probe positions, eliminating the need for cumbersome cables while enabling automated location tracking
Solution Approach 2:
The system adds a spatial dimension to probe tracking by using signal intensity variations across multiple base stations. By measuring signal strengths from different spatial locations (multiple base stations), the system can triangulate probe positions in two-dimensional space, transforming the tracking problem from invisible wireless signals to measurable spatial data
3Reliability
If multiple fetal monitors are arranged in one ward for one-to-one monitoring, then monitoring quality is improved, but device quantity, occupied area and electricity consumption increase
Solution Approach 1:
The data management center serves as a universal platform that can manage multiple probes and base stations simultaneously. Instead of requiring separate dedicated monitors for each patient, the centralized system provides multi-functional capabilities to handle monitoring data from multiple sources, reducing the total number of devices needed in the ward
Solution Approach 2:
The patent merges multiple monitoring functions into a single centralized data management center. By combining data collection, processing, and management capabilities into one unified system, the patent reduces the number of separate monitors needed, thereby decreasing occupied space and electricity consumption while maintaining comprehensive monitoring coverage

AI summary
The invention relates to a method for locating wireless fetal monitoring probes in a set area. The method comprises the following steps: instructions are sent via a plurality of wireless base stations to instruct the wireless probes in the action scopes of the wireless base stations to send base station signal intensity data tables; the wireless probes search all receivable base station signals, establish the base station signal intensity data tables in which signal intensities of the base stations are arranged according to the serial numbers of the base stations, and send the base station signal intensity data tables to a data management center; operations are carried out based on the received current base station signal intensity data tables and base station signal intensity data tables of reference points to obtain a distance reference table; the position of one with the smallest distance value is selected to be regarded as the current position of the corresponding probe. The invention further relates to a device for implementing the method. The method and the device for locating the wireless fetal monitoring probes in the set area have the benefits of quickly locating each wireless probe and avoiding loss of monitoring data.
