Degassed Drink Solution for Stomach Endoscopy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas bubble formation in the stomach during endoscopic procedures, particularly in capsule endoscopy, leads to measurement errors due to reactions between the expansion liquid and gastric juices, causing optical distortions and navigability issues with magnetically guided capsules.
Innovation Solution
A degassed aqueous drink solution is used, which is freed of dissolved gases like CO2, N2, and O2, and may include additives such as silicone oil for defoaming and a pH buffer to maintain stable conditions, reducing bubble formation and improving navigability and measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If an aqueous drink solution is used to expand the stomach during endoscopy, then the stomach can be adequately expanded for examination, but gas bubble formation occurs due to reactions with gastric juices causing measurement errors
Solution Approach 1:
The drink solution is pre-treated by degassing to remove dissolved gases before administration to the patient. This preliminary action prevents gas bubble formation during the endoscopic examination, eliminating optical distortions and measurement errors while maintaining stomach expansion capability
Solution Approach 2:
The patent changes the physical-chemical parameters of the drink solution by adjusting pH and adding defoaming agents. These parameter modifications prevent gas bubble formation and stabilize the solution's interaction with gastric juices, thereby improving measurement precision while maintaining adequate stomach expansion
2Measurement precision
If a degassed drink solution is used to prevent gas bubble formation, then measurement precision is improved, but the solution requires additional processing steps
Solution Approach 1:
The drink solution is pre-degassed and pre-adjusted in pH before patient administration. This preliminary preparation eliminates the need for complex real-time adjustments during the procedure, improving measurement precision while the processing is completed in advance
Solution Approach 2:
Defoaming agents are added as intermediary substances to the drink solution. These agents mediate between the solution and gastric juices, preventing gas bubble formation through chemical action and simplifying the overall system by eliminating the need for complex mechanical or procedural interventions
3Ease of operation
If regular drink solution is administered to expand the stomach, then the procedure is simple to implement, but gas bubbles adhere to capsule surfaces reducing navigability
Solution Approach 1:
The drink solution is pre-degassed and defoamed before administration to maintain capsule navigability during magnetically guided capsule endoscopy, while still providing adequate stomach expansion
Solution Approach 2:
The pH of the drink solution is adjusted and defoaming agents are added to change its physical-chemical properties. These changes prevent gas bubble formation on capsule surfaces, maintaining navigability while preserving the simplicity of oral administration
