Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sputum-suction devices require operators to manually monitor blood oxygen levels and switch between oxygen supply and suction functions, making the process inconvenient and operator-dependent.
Innovation Solution
An intelligent exhaled sputum-suction and inhaled oxygen-supply device with a sputum-suction and oxygen-supply tube unit, a gas-regulating unit, and a control unit that uses a respiration sensor to automatically adjust oxygen supply and sputum suction based on the patient's breathing state, integrating a major oxygen-supply tube, a major sputum-suction tube, an oxygen-supply module, a sputum-suction module, and a respiration sensor to synchronize oxygen inhalation with sputum exhalation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual monitoring and switching between oxygen supply and suction functions is used, then the operator can control the device, but the operating process becomes inconvenient and requires experienced operators
Solution Approach 1:
The device automatically detects patient breathing state through the respiration sensor and autonomously switches between oxygen supply and sputum suction modes without requiring manual intervention. The control unit processes sensor signals and activates appropriate modules, enabling the system to serve itself and eliminate the need for experienced operators to manually monitor and switch functions.
Solution Approach 2:
The respiration sensor continuously monitors the patient's breathing state and provides feedback signals to the control unit. Based on this real-time feedback, the control unit automatically adjusts the device function - activating the oxygen-supply module during inhalation and the sputum-suction module during exhalation, creating a closed-loop control system that simplifies operation.
2Reliability
If the suction tube is removed immediately when blood oxygen concentration decreases, then oxygen supply can be restored, but the operator must cautiously observe and move the tube simultaneously which is inconvenient
Solution Approach 1:
The device autonomously monitors breathing state through the respiration sensor and automatically switches between suction and oxygen supply modes. When the patient is in inhalation state, the system automatically activates oxygen supply and deactivates suction, eliminating the need for operators to manually remove tubes based on oxygen concentration observations.
Solution Approach 2:
The manual mechanical action of removing the suction tube is replaced by an automated electronic control system. The control unit electronically switches between modules based on sensor input, replacing the need for manual tube manipulation and simultaneous observation of oxygen concentration.
3Productivity
If automatic breathing state detection is implemented, then oxygen supply and sputum suction can be synchronized with breathing cycles, but additional sensors and control systems are required
Solution Approach 1:
The respiration sensor provides continuous feedback on patient breathing state (inhalation or exhalation phase) to the control unit. This feedback mechanism enables automatic synchronization of oxygen supply and sputum suction with the patient's natural breathing cycles, improving procedural efficiency through real-time adaptive control.
Solution Approach 2:
The device uses the respiration sensor to autonomously determine when to activate oxygen supply versus sputum suction functions. The control unit processes sensor data and automatically manages module activation, enabling the system to self-regulate based on patient needs without requiring additional manual monitoring equipment or complex external control systems.
