Fecal Impaction Removal Device with Asymmetric Spoon Rim
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for removing fecal impaction, such as using tablespoons, pose a risk of injury to surrounding tissues and organs due to inadequate precision and stability, and are not effective in quickly and safely dislodging and removing impacted stool.
Innovation Solution
A fecal impaction removal device with a spoon-shaped design featuring a rounded or indented edge, a conical head with increased wall thickness, and a handle system that allows for controlled insertion and scraping, along with a flushing line and guide channel for observation and additional tool access, reduces tissue trauma and enhances removal efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional tablespoons are used to mechanically assist in breaking up impaction, then the removal of stool impaction can be achieved, but the risk of injury to tissue and organs increases
Solution Approach 1:
The spoon rim is designed with different edge surface shapes (upwardly rounded or downwardly indented) at different locations to provide locally optimized cutting actions. The upwardly rounded edge provides a gentle cutting action for softer stool, while the downwardly indented edge provides a sharper cutting action for harder stool, thereby reducing tissue injury risk while maintaining removal efficiency
Solution Approach 2:
The specially designed spoon rim with controlled edge surfaces acts as an intermediary between the mechanical force applied and the stool impaction. The rounded or indented edge surfaces intermediate the force application to reduce direct trauma to surrounding tissues while still effectively breaking up the impaction
2Object-affected harmful factors
If the spoon rim has a rounded upwards edge surface for gentle action, then tissue trauma is reduced, but the ability to cut extremely hardened feces is diminished
Solution Approach 1:
The spoon rim can be designed with asymmetric edge surfaces, where one side has an upwardly rounded edge for gentle action and the other side has a downwardly indented edge for sharp cutting. This asymmetry allows the single spoon to provide both gentle and sharp cutting actions depending on the orientation and type of stool impaction encountered
3Reliability
If the conical head region has increased wall thickness for mechanical stability, then insertion and scraping forces are better controlled, but the device complexity increases
Solution Approach 1:
The spoon section is designed with non-uniform wall thickness, where the conical head region has increased wall thickness (more than 50%, preferably more than 100% greater than the sidewall section) to provide mechanical stability during insertion and scraping, while other regions maintain thinner walls to reduce overall device complexity and material usage
