Patient Support Controller Accessory Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In surgical and diagnostic procedures, person support apparatuses require proper setup to prevent harm to patients and equipment, with existing systems lacking effective mechanisms to ensure accessories are properly attached and functionalities are enabled or disabled based on the setup.
Innovation Solution
A system where a controller communicatively couples with removable components of the person support apparatus to determine their presence or absence, enabling or disabling movements and functionalities accordingly, ensuring safe and appropriate patient positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support apparatus is equipped with multiple accessories and functionalities for different surgical procedures, then the adaptability and versatility of the apparatus is improved, but the risk of harm to patients or equipment increases if the apparatus is not set up properly
Solution Approach 1:
The system performs preliminary verification by detecting the presence and proper attachment of accessories (such as restraints) before enabling the support apparatus to perform movements or procedures. The controller checks for accessory presence through communicative coupling and only allows operational functions after successful verification, ensuring proper setup before use.
2Productivity
If the support apparatus enables all movement and functional capabilities, then the productivity and operational flexibility is improved, but the safety and reliability decreases without proper setup verification
Solution Approach 1:
The controller continuously monitors the status of accessories through communicative coupling and provides feedback control. Based on the detected presence or absence of accessories, the controller dynamically enables or disables specific movements and functionalities, ensuring that the apparatus operates safely while maintaining maximum operational flexibility when properly configured.
3Reliability
If the apparatus includes comprehensive tracking and verification systems for accessories, then the reliability and safety is improved, but the device complexity increases
Solution Approach 1:
The accessories themselves perform self-identification and status reporting functions through their communicative coupling capabilities. Each accessory can independently communicate its presence, attachment status, and operational readiness to the controller, eliminating the need for complex external verification systems while maintaining high reliability.

AI summary
Systems and processes of controlling a function of a person support apparatus are provided. An example system includes a person support apparatus adapted to support a patient. The person support apparatus comprising a controller adapted to communicatively couple with at least one removable component of the person support apparatus. The controller is adapted to determine the absence or presence of the at least one removable component. In response to the determination, the controller is further adapted to disable at least one movement of the person support apparatus in response to a determination that the at least one removable component is not present or enable the at least one movement in response to a determination that the at least one removable component is present.
