Solution Overview
Problem
Current medical emergency equipment is limited in duration and cannot sustain a patient's life beyond immediate cardiac arrest, requiring urgent hospital transport for further interventions.
Innovation Solution
A portable medical emergency equipment with a load-bearing frame, integrated defibrillator, cardiac massage means, and extracorporeal blood circulation circuit, controlled by an electronic unit to synchronize and modulate treatment based on patient vital signs, allowing prolonged therapeutic support during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If mechanical means for cardiac massage are applied on a load-bearing frame, then cardiac compression can be performed, but the equipment cannot sustain patient life beyond immediate cardiac arrest
Solution Approach 1:
The patent combines multiple life-sustaining functions (cardiac massage, defibrillation, and extracorporeal blood circulation) into a single integrated portable device. The blood circulation circuit is merged with the cardiac massage mechanism, allowing both functions to operate synergistically during transport, thereby extending therapeutic support duration without proportionally increasing device complexity
Solution Approach 2:
The load-bearing frame is designed as a multi-functional platform that simultaneously supports cardiac massage application, houses blood circulation components, accommodates defibrillator, and provides patient transport capability. This universal design allows one device to perform multiple critical functions that would otherwise require separate equipment
2Ease of operation
If equipment is made portable for transport, then patient can be transported to hospital, but therapeutic support duration is limited
Solution Approach 1:
The equipment establishes extracorporeal blood circulation before hospital arrival, preliminarily sustaining patient life during transport. The portable device performs life-sustaining functions in advance during the critical transport period, allowing medical staff to continue interventions upon arrival without interruption
Solution Approach 2:
The device transitions from a static load-bearing frame to a dynamic life-sustaining system during transport. The blood circulation circuit and cardiac massage mechanisms are activated dynamically during movement, adapting therapeutic support to patient needs throughout the transport journey rather than being limited to fixed locations
3Reliability
If blood circulation circuit is integrated with cardiac massage means, then patient can be kept alive during transport, but device complexity increases
Solution Approach 1:
The blood circulation components are nested within the load-bearing frame structure, with tubing and pumps integrated into the existing framework. The defibrillator and cardiac massage mechanisms are similarly nested, creating a compact hierarchical arrangement that reduces overall system complexity compared to separate equipment
