Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional ventilators are used without CO2 compensation functionality, then the device structure remains simple, but the patient suffers from respiratory alkalosis or acidosis due to imprecise control of end-tidal carbon dioxide levels
Solution Approach 1:
The patent extracts the CO2 compensation functionality as a separate modular device that can be connected to universal ventilators. This allows the ventilator structure to remain relatively simple while adding the necessary CO2 control capabilities through an external compensator that interfaces with the existing ventilator system.
Solution Approach 2:
The CO2 compensator is designed to be universally compatible with different ventilator models through standardized connections. This multi-functionality approach allows a single compensator device to work with various ventilators, reducing overall system complexity while improving CO2 control reliability across different platforms.
2Reliability
If bag or collection device is used to cover patient's mouth and nose for re-inhaling exhaled carbon dioxide, then the structure is simple, but the amount of carbon dioxide cannot be precisely controlled or monitored
Solution Approach 1:
The patent incorporates sensors that continuously monitor end-tidal CO2 levels and provide feedback to the control system. This feedback mechanism enables precise control of CO2 delivery by adjusting the compensation based on real-time measurements, ensuring reliable CO2 level management while maintaining reasonable device complexity through automated control.
Solution Approach 2:
The patent replaces the purely mechanical bag-based CO2 recycling system with an electronically controlled gas delivery system. This substitution introduces precise control capabilities through electronic regulation of gas flow and composition, while the modular design keeps the overall device complexity manageable.
3Reliability
If oxygen mask with gas storage device is used to allow re-inhaling of exhaled carbon dioxide, then the patient comfort improves, but the device cannot precisely monitor and adjust incoming carbon dioxide to reflect patient's end-tidal carbon dioxide situation
Solution Approach 1:
The patent integrates end-tidal CO2 sensors that continuously monitor the patient's respiratory gases and provide real-time feedback to the control system. This enables accurate monitoring of end-tidal CO2 levels and automatic adjustment of the CO2 compensation, ensuring reliability while managing device complexity through intelligent control algorithms.
Solution Approach 2:
The system is designed to automatically adjust CO2 delivery based on sensor feedback without requiring manual intervention. The compensator self-regulates the gas mixture and flow rates to maintain target end-tidal CO2 levels, improving monitoring accuracy while keeping the device structure manageable through automated self-adjustment capabilities.

AI summary
A This invention provides a CO2 and other gas compensation device and system connected to a universal ventilator, related to the medical technology field. It includes the device body, which contains a respiratory gas CO2 compensation device. Inside the respiratory gas CO2 compensation device, an airway is set up. The output end of the airway is connected to a respiratory parameter detection module, which is connected to the respiratory terminal. Inside the respiratory terminal, a proximal pressure sensor and an end-tidal carbon dioxide sensor are installed. The proximal pressure sensor and the end-tidal carbon dioxide sensor are electrically connected to the respiratory gas CO2 compensation device, respectively. In this invention, carbon dioxide is compensated into the respiratory terminal through the respiratory gas CO2 compensation device. The respiratory parameter detection module can monitor the parameters of the incoming carbon dioxide. The respiratory gas CO2 compensation device, in coordination with the respiratory parameter detection module, achieves precise monitoring and adjustment of the incoming carbon dioxide, thereby accurately controlling the amount of carbon dioxide compensation required by the patient and improving the treatment effect.
