Patient Support Deck Motion Unlocking for CPR Reconfiguration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing patient support apparatuses, such as hospital beds or stretchers, often have motion locks that prevent movement of the patient support deck during emergency situations like CPR, making it difficult to reconfigure the deck for optimal CPR performance.
Innovation Solution
A patient support apparatus with a support structure, actuators, and a controller that includes a motion lock module with configurable electronic locks, allowing automatic unlocking during emergency events to facilitate deck reconfiguration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motion locks are activated to prevent movement of the patient support deck, then safety and stability are improved, but ease of operation deteriorates when reconfiguration is needed
Solution Approach 1:
The system performs preliminary action by automatically unlocking motion locks when an emergency event is detected, preparing the patient support deck for rapid reconfiguration before the caregiver needs to act. This eliminates the need for manual lock disengagement during emergencies.
Solution Approach 2:
The system uses feedback from emergency detection (such as CPR detection sensors or manual emergency buttons) to automatically change the state of motion locks from locked to unlocked, enabling the deck to be reconfigured when needed while maintaining safety during normal operation.
2Stability of the object's composition
If motion locks are activated to prevent movement, then stability is improved, but productivity deteriorates during emergency reconfiguration
Solution Approach 1:
The system performs preliminary action by automatically unlocking motion locks when an emergency event is detected, preparing the patient support deck for rapid reconfiguration before the caregiver needs to act. This eliminates the need for manual lock disengagement during emergencies.
Solution Approach 2:
The system performs self-service by automatically detecting emergencies and unlocking motion locks without requiring manual intervention from the caregiver. This speeds up the reconfiguration process and improves productivity during critical moments.
3Adaptability or versatility
If electronic motion locks are made configurable with multiple states, then adaptability is improved, but device complexity increases
Solution Approach 1:
The motion lock system serves multiple functions: it can be locked during normal operation for safety, automatically unlocked during emergencies for rapid access, and configured in different states to accommodate various clinical scenarios. This multi-functionality provides adaptability without proportionally increasing complexity.
Solution Approach 2:
The system performs self-service by automatically detecting emergencies and unlocking motion locks without requiring manual intervention from the caregiver. This speeds up the reconfiguration process and improves productivity during critical moments.

AI summary
A patient support apparatus is provided for sensing and responding to an emergency event. The patient support apparatus includes a plurality of actuators to lift and lower a patient relative to a floor surface and to articulate one or more deck sections. An activator is coupled to the support structure to be actuated by a user to signal the emergency event. A plurality of electronic motion locks can be configured to a locked or unlocked state. In the locked state, a controller prevents operation of one or more of the actuators. The controller is configured to automatically reset the motion locks to their unlocked states in response to detecting the emergency event.
