Insufflation Device Gas Sensor for Explosive Mixture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During endoscopic procedures, there is a risk of explosive gas mixtures forming in the abdominal cavity due to insufflation gases like nitrous oxide and methane, which can lead to serious complications or death if not detected promptly, and existing methods for gas analysis are impractical for real-time monitoring during surgeries.
Innovation Solution
An insufflation device with a built-in withdrawal line and a gas sensor for continuous monitoring of the gas mixture, allowing for early detection of explosive gases and intestinal damage, with optional modules for specific gas detection and alarm systems to alert the physician.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gas analysis is performed using a catheter and gastight syringe as described in prior art, then gas composition can be measured, but the method is too complicated and time-consuming for real-time monitoring during endoscopic procedures
Solution Approach 1:
The patent extracts the gas sampling function from the complex catheter-syringe procedure and integrates it directly into the insufflation device. A gas sampling port is built into the insufflation device, allowing direct connection of the gas sensor to the insufflation gas flow, thereby eliminating the need for separate catheter insertion and syringe-based sampling procedures.
Solution Approach 2:
The patent merges the gas analysis function with the insufflation device by integrating a gas sensor directly into the insufflation system. This combination allows continuous real-time monitoring of gas composition during the procedure, rather than requiring separate, discrete sampling operations.
2Reliability
If continuous real-time gas monitoring is implemented during endoscopic procedures, then early detection of explosive gas mixtures and intestinal damage is enabled, but device complexity and cost increase
Solution Approach 1:
The insufflation device monitors its own output gas composition in real-time through an integrated gas sensor. The system automatically detects changes in gas composition, such as the presence of explosive gases or indicators of intestinal perforation, and can trigger alarms or adjust insufflation parameters without requiring separate monitoring equipment or manual intervention.
Solution Approach 2:
The gas sensor provides continuous feedback on the composition of gas in the abdominal cavity. This feedback loop allows the system to detect hazardous conditions early and alert the surgeon, enabling immediate corrective action. The monitoring data can also be used to adjust insufflation rates dynamically to maintain safe gas composition levels.
3Reliability
If higher concentrations of nitrous oxide are used for anaesthesia, then anaesthetic effectiveness is improved, but the risk of explosive gas mixtures in the abdominal cavity increases
Solution Approach 1:
The gas sensor continuously monitors nitrous oxide concentration in the abdominal cavity, providing real-time feedback to the surgical team. When nitrous oxide levels approach dangerous thresholds, the system can alert the surgeon to reduce anaesthetic concentration or increase carbon dioxide insufflation to dilute the mixture, thereby maintaining both effective anaesthesia and safety.
Solution Approach 2:
The system dynamically adjusts gas composition parameters to maintain safe operating conditions. By monitoring the composition of gases in the abdominal cavity, the system can recommend or automatically adjust the ratio of nitrous oxide to carbon dioxide, ensuring that the anaesthetic remains effective while the explosive risk is kept below dangerous levels.
4Productivity
If electrosurgical instruments are used during insufflation, then surgical precision and efficiency are improved, but the risk of gas explosions and intestinal damage detection becomes more critical
Solution Approach 1:
The gas sensor provides continuous monitoring of gas composition during electrosurgical procedures, detecting the presence of explosive gases or indicators of intestinal perforation in real-time. This feedback allows the surgical team to take immediate corrective action, such as stopping electrosurgery or adjusting gas insufflation, thereby maintaining surgical efficiency while preventing catastrophic complications.
