Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If medical personnel manually evaluate airway status through multiple operations (intubation, cuff operation, ventilator setting), then the evaluation can be performed, but the evaluation accuracy decreases due to operational complexity
Solution Approach 1:
The patent combines multiple separate operations (intubation, cuff inflation/deflation, ventilator setting, and airway status evaluation) into a single integrated automated system. The evaluation apparatus automatically performs all these functions through coordinated control of the ventilator, cuff inflation/deflation device, and monitoring systems, eliminating the need for multiple manual operations by medical personnel and thereby improving evaluation accuracy.
Solution Approach 2:
The system enables self-service evaluation by automatically monitoring respiratory parameters, controlling cuff pressure, and assessing airway status without requiring continuous manual intervention. The automated apparatus performs the evaluation independently, reducing human error and operational complexity while maintaining high measurement precision.
2Reliability
If cuff pressure is excessively high to ensure airway sealing, then the airway patency is maintained, but airway damage occurs due to insufficient blood supply to tracheal mucosa
Solution Approach 1:
The patent implements a feedback control system that continuously monitors cuff pressure and respiratory parameters. The system automatically adjusts cuff pressure to maintain optimal sealing while preventing excessive pressure that could cause airway damage. The feedback mechanism ensures the cuff pressure remains within a safe range by comparing real-time measurements with predetermined thresholds and making automatic adjustments.
Solution Approach 2:
The system dynamically changes cuff pressure parameters based on real-time airway status monitoring. By automatically adjusting the pressure level according to measured respiratory parameters and airway patency, the system maintains reliable sealing while avoiding the harmful effects of excessively high pressure on tracheal mucosa blood supply.
3Measurement precision
If automated evaluation apparatus is used to monitor respiration parameters and control cuff inflation/deflation, then evaluation accuracy is improved, but device complexity increases
Solution Approach 1:
The evaluation apparatus is designed as a multi-functional integrated system that combines respiratory monitoring, cuff inflation/deflation control, and airway status evaluation into a single universal device. This universal apparatus can perform multiple functions simultaneously, improving evaluation accuracy while minimizing the need for separate devices and reducing overall system complexity.

AI summary
An airway status evaluation apparatus includes a respiration monitoring unit, a data processing unit, an inflation/deflation unit, and an inflation/deflation control unit. The data processing unit is electrically connected to the respiration monitoring unit, collects a respiration parameter of a patient from the respiration monitoring unit when a cuff meets an evaluation state, and evaluates an airway status of the patient according to the respiration parameter. The inflation/deflation control unit is connected to the inflation/deflation unit and controls the inflation/deflation unit to inflate and deflate the cuff so as to enable the cuff to meet an evaluation state. In the present disclosure, inflation and deflation of the cuff are implemented in a full-automatic or semi-automatic control manner, the respiration parameter can be automatically monitored, and the evaluation result is automatically calculated, thereby achieving the automatic evaluation for the airway status of a patient.
