Solution Overview
Problem
Current patient support apparatuses lack effective monitoring systems for radiation doses received by patients during medical procedures, which can lead to inadequate exposure control and potential health risks.
Innovation Solution
A radiation monitoring system integrated with a patient support apparatus, featuring a radiation sensor assembly that translates between ends of the support member, coupled with a first controller to sense and communicate radiation data to a management system for storage in a patient profile database, ensuring accurate and real-time monitoring of radiation doses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a radiation sensor assembly is integrated with the patient support apparatus, then radiation dose monitoring capability is improved, but device complexity increases
Solution Approach 1:
The radiation sensor assembly is integrated with the patient support apparatus by coupling the sensor assembly to the support member. The support member itself serves as part of the mounting structure, merging the monitoring function with the existing support structure rather than adding a completely separate system.
Solution Approach 2:
The support member is designed to serve multiple functions: it provides patient support and simultaneously serves as a mounting structure for the radiation sensor assembly. This multi-functionality reduces the need for additional dedicated components solely for sensor mounting.
2Adaptability or versatility
If the radiation sensor assembly translates between ends of the support member, then measurement coverage is improved, but device complexity increases
Solution Approach 1:
The radiation sensor assembly is configured to be movable along the support member between its first and second ends. This dynamic positioning capability allows the sensor to be relocated to different positions to monitor radiation doses at various areas, improving measurement coverage without requiring multiple fixed sensor assemblies.
Solution Approach 2:
The monitoring function is segmented into a movable sensor assembly that can be positioned at different locations along the support member. This allows a single sensor to cover multiple measurement zones sequentially, replacing what would otherwise require multiple fixed sensors simultaneously.
3Loss of information
If radiation data is automatically communicated and stored in a management system, then information accuracy is improved, but device complexity increases
Solution Approach 1:
The first controller automatically communicates radiation data to a second controller in a management system, creating a feedback loop that ensures accurate recording and tracking of radiation doses. This automated feedback mechanism eliminates manual data transfer errors and maintains information accuracy.
Solution Approach 2:
The system performs self-service by automatically communicating and storing radiation data without requiring manual intervention. The first controller autonomously transfers data to the management system, and the second controller automatically stores it in the patient profile database, reducing the need for manual data entry and minimizing human error.
