Solution Overview
Problem
Current patient monitoring systems face challenges in efficiently managing cables, leading to discomfort, interference with patient movement, and increased complexity in data transmission between sensors and monitoring devices.
Innovation Solution
The system incorporates a design where sensors like ECG devices and blood pressure monitors connect indirectly to the patient monitor, reducing cable length and improving cable management through bypass functionality and modular components, allowing for flexible and efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors are connected directly to the patient monitor using cables, then data transmission is established, but cable management becomes complex and patient comfort is reduced
Solution Approach 1:
The patent introduces a wireless communication module as an intermediary between the sensor and the patient monitor. The sensor transmits data wirelessly to the monitor, eliminating the need for physical cable connections while maintaining reliable data transmission. This resolves the contradiction by providing an alternative communication path that avoids cable management issues.
2Reliability
If cables are used to connect sensors to the patient monitor, then data transmission is enabled, but patient movement is interfered with and comfort is reduced
Solution Approach 1:
The patent replaces the mechanical cable connection system with a wireless communication system. The sensor and patient monitor communicate through wireless signals (such as radio frequency), eliminating the physical constraint of cables. This allows patients to move freely without cable interference while maintaining reliable data transmission.
3Adaptability or versatility
If multiple cables are used for different sensors, then comprehensive monitoring is achieved, but cable complexity and interference increase
Solution Approach 1:
The patent implements a universal wireless communication protocol that can handle multiple types of sensor data (ECG, blood pressure, temperature, etc.) through a single communication channel. The patient monitor is designed to receive and process various physiological parameters wirelessly, eliminating the need for separate cables for each sensor type. This reduces cable complexity while maintaining comprehensive monitoring capability.
