Vital Sign Telemeter with Integrated Cuff and Wireless Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vital sign telemeters are cumbersome and restrict patient mobility due to their large configuration and complex sensor wiring, making it difficult to monitor multiple vital signs simultaneously, especially in emergency situations.
Innovation Solution
A compact, lightweight vital sign telemeter that integrates a blood pressure cuff, detectors for electrocardiogram, respiration, oxygen saturation, and carbon dioxide concentration into a single unit on the patient's upper arm, with a detachable main body and wireless data transmission for remote monitoring, ensuring easy handling and reduced patient burden.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a vital sign telemeter integrates multiple detectors and processing functions into a single unit for compactness, then device complexity and wiring are reduced, but measurement precision and reliability may be compromised
Solution Approach 1:
The vital sign telemeter is segmented into separate functional modules: a blood pressure measurement module with cuff, an ECG module with electrodes, a respiration module with impedance sensors, and an SpO2 module with optical sensors. Each module independently measures its specific vital sign parameter, then all modules connect to a central processing unit. This segmentation allows each detector to be optimized for its specific measurement function while the overall system remains integrated and compact, resolving the contradiction between device complexity and measurement precision.
2Adaptability or versatility
If a vital sign telemeter uses multiple sensors and processing components for comprehensive monitoring, then measurement capability is improved, but the device becomes large and restricts patient mobility
Solution Approach 1:
The telemeter employs a nested structure where the main processing unit is housed within the blood pressure cuff, and other sensor modules (ECG electrodes, SpO2 sensor, respiration sensors) are attached to or integrated with the cuff structure. This nesting allows multiple measurement functions to be combined in a compact form factor that can be worn on the patient's arm without excessive bulk, resolving the contradiction between comprehensive monitoring capability and device size.
3Ease of operation
If a vital sign telemeter integrates all detectors and processors into one unit, then ease of operation is improved, but safety may be compromised when single fault conditions occur
Solution Approach 1:
The telemeter incorporates preliminary safety actions through redundant measurement pathways and pre-programmed fault detection algorithms. The system continuously monitors for single fault conditions (such as sensor failures, wiring issues, or processing errors) and automatically switches to alternative measurement methods or alerts the user before measurement accuracy deteriorates. This preliminary fault management allows the integrated design to maintain both ease of operation and reliability under fault conditions.
