Condom Catheter Suction Seal for Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condom catheters often leak or detach from the penis, failing to provide effective urinary diversion and leading to urinary tract infections and other complications.
Innovation Solution
A condom catheter design utilizing low-pressure suction to secure the device to the penis, creating a vacuum seal between the condom catheter and the penis shaft, with a side port for suction application to prevent leakage and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesives or elastic materials are used to secure the condom catheter to the penis, then the device can be attached to the penis, but the catheter still leaks or detaches and fails to provide reliable securing
Solution Approach 1:
The patent applies pneumatic principles by using negative pressure (suction) generated through the side wall port to create a vacuum seal between the condom catheter and the penis shaft. This pneumatic securing mechanism replaces traditional adhesive or elastic band methods, providing reliable attachment without the leakage and detachment problems associated with those conventional approaches.
2Reliability
If a vacuum seal is created using a vacuum system or syringe through the side port, then the condom catheter is firmly attached to the penis, but the device requires additional components and operational steps
Solution Approach 1:
The condom catheter design allows the patient or caregiver to create the vacuum seal themselves using simple manual methods. The side wall port enables direct connection to a syringe or vacuum source, allowing the user to generate and maintain the negative pressure needed for secure attachment without requiring complex automated systems or specialized equipment.
3Reliability
If the condom catheter design includes a side wall port for suction application, then the catheter can be securely attached, but the manufacturing process becomes more complex
Solution Approach 1:
The side wall port is designed as an integrated feature of the condom catheter structure, allowing the vacuum sealing function to be incorporated into the basic manufacturing process. The port can be formed as part of the extrusion or molding process, segmenting the vacuum function from the main tube structure while maintaining manufacturing efficiency through standardized production techniques.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The suction-based design effectively secures the condom catheter to the penis, reducing leakage and detachment, and allows for efficient urinary diversion through gravity or suction, improving patient comfort and reducing infection risks.
Implementation Method 1
A vacuum, or negative pressure suction, is applied between the inner surface of the condom catheter proximal part and the shaft of the penis allowing firm adhesion of the condom catheter to the penis's shaft
Implementation Method 2
the distal penile urethral opening of the condom catheter is allowed to drain freely into common urinary closed collection bag systems by gravity or suction
