EMS Cot Mechanical CPR Device for Prone Position Compressions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mechanical cardiopulmonary resuscitation (CPR) systems in emergency medical services (EMS) face challenges in providing timely chest compressions for patients in prone positions, as rotating them to a supine position for CPR can be time-consuming, potentially delaying necessary interventions during cardiac emergencies.
Innovation Solution
Integration of a built-in mechanical compression device into EMS cots and gurneys that can provide compressions in both supine and prone positions, featuring a reciprocating plunger or inflatable bladder mechanism, along with alignment and retention systems to ensure accurate and efficient chest compression delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a patient is positioned in prone position for breathing enhancement, then ventilation of dorsal lungs is improved, but chest compressions cannot be provided if cardiac arrest occurs
Solution Approach 1:
The mechanical compression device is designed to perform CPR functions in multiple patient positions (supine and prone), making the device universal across different clinical scenarios. The device can deliver chest compressions whether the patient is lying on their back or stomach, eliminating the need to reposition the patient for CPR intervention.
Solution Approach 2:
Instead of requiring the patient to be in the traditional supine position for chest compressions, the device enables compressions to be delivered effectively in the prone position as well. This inverts the conventional approach by making the prone position viable for CPR, allowing simultaneous ventilation benefit and cardiac compression capability.
2Reliability
If patient is rotated from prone to supine position for CPR, then chest compressions can be provided, but time is lost delaying critical intervention
Solution Approach 1:
The mechanical compression device is pre-positioned and ready to deliver compressions regardless of patient orientation. By having the capability built into the cot system in advance, no time is lost repositioning the patient or setting up equipment - CPR can begin immediately in the prone position if cardiac arrest occurs.
Solution Approach 2:
The device is designed to dynamically adapt to different patient positions (supine and prone) without requiring physical repositioning of the patient. The mechanical system can adjust its compression delivery mechanism to effectively compress the chest in either orientation, making the transition between positions instantaneous rather than requiring time-consuming manual rotation.
3Productivity
If mechanical compression device is integrated into EMS cot, then immediate CPR is possible in both positions, but device complexity increases
Solution Approach 1:
The mechanical compression device is integrated directly into the EMS cot structure, merging the CPR function with the existing patient support system. This combination eliminates the need for separate portable CPR devices and reduces overall system complexity by consolidating functions into a single integrated platform.
Solution Approach 2:
The integrated device serves multiple functions: it provides structural support as part of the cot system and delivers mechanical CPR compressions in both supine and prone positions. This multi-functionality justifies the added complexity by providing versatile capability that addresses multiple clinical needs with a single system.

AI summary
Examples of the disclosure are directed to a patient support apparatus including a frame having a deck structured to support a patient, a retention device structured to secure the patient on the deck, and a compression device attached to the frame at the deck, the compression device including a compression mechanism structured to extend toward the patient and retract at least partially below the deck. In some examples, the compression device includes an inflatable bladder or a rotating cam having a lobe to provide the compression.
