Insufflation Retention Device Balloon Seal for Body Aperture Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for introducing a probe into a body cavity for diagnostic or therapeutic interventions often fail to effectively retain insufflation material due to inadequate sealing at the body aperture, particularly in cases with congenital malformations or structural injuries, leading to leakage and reduced operational time and visibility for the operator.
Innovation Solution
An insufflation retention device (IRD) is designed to form effective seals between the body aperture and the probe, utilizing internal and external buttresses that expand with insufflation material to prevent leakage and ensure retention of insufflation material within the body cavity, thereby facilitating better access and visibility for interventions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a probe is introduced into a body cavity through a body aperture, then diagnostic or therapeutic interventions can be performed, but insufflation material leaks due to inadequate sealing at the body aperture
Solution Approach 1:
An insufflation retention device is introduced as an intermediary component between the body aperture and the probe. This device includes a retention portion that forms a seal with the body aperture and a passageway that accommodates the probe, thereby preventing insufflation material leakage while allowing probe insertion for interventions.
Solution Approach 2:
The insufflation retention device is divided into distinct functional segments: a retention portion for sealing with the body aperture, a passageway for probe insertion, and an insufflation material retention chamber. This segmentation allows each component to perform its specific function effectively.
2Reliability
If the body aperture forms a seal with the probe, then insufflation material can be retained, but the seal fails in cases with congenital malformations or structural injuries
Solution Approach 1:
The retention portion of the insufflation retention device is designed with specific local qualities to accommodate abnormal anatomy. It includes features such as a retention flange that can engage with varied tissue structures and a balloon portion that can be inflated to different volumes to achieve effective sealing despite congenital malformations or structural injuries.
3Productivity
If the body cavity is expanded for better visibility and access, then operational time is improved, but sealing requirements become more challenging
Solution Approach 1:
The balloon portion of the insufflation retention device can be inflated to different volumes to change its sealing parameters. This allows the device to adapt to varying cavity sizes and maintain effective sealing while accommodating expanded body cavity volume for improved operational time and visibility.

Function Achieved in This Case
The IRD effectively retains insufflation material, enhancing the operator's ability to perform interventions by maintaining a stable and expanded body cavity, even in cases with abnormal anatomical conditions, thereby improving operational time and visibility.

AI summary
A probe may be inserted into a body cavity to perform diagnostic intervention(s), therapeutic intervention(s), or both. The probe may be inserted through a body aperture that is naturally occurring or man-made, intentionally or by accident. The body aperture may form a seal encircling the probe so that insufflation retention material may be effectively retained in the body cavity so that an operator can perform the intervention(s). However, there may be leakage of the insufflation material. The insufflation retention device is configured to form an effective seal contactingly adjacent the body aperture and to provide a passageway for the introduction of the probe into the body cavity, such that a diagnostic intervention or therapeutic intervention or both may be performed.
