Solution Overview
Problem
Current solutions for female stress urinary incontinence, fecal incontinence, menstrual blood collection, and laparoscopic surgeries face issues such as device slippage, inconsistent results, and gas leakage, with existing devices like vaginal cones, weights, and menstrual cups being inefficient and inconvenient.
Innovation Solution
A Multipurpose Vaginal Occlusion and Distension Device with a cylindrical construction and Distension Control and Release Mechanism, featuring inflatable tubular ribs, annular spaces, and a detachable gas inflow inlet, providing secure fit, controlled pressure, and adjustable fitment for various applications, including urinary incontinence, menstrual blood collection, and laparoscopic surgeries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vaginal cones or weights are used for stress urinary incontinence, then the device provides occlusion and resistance training, but the device slips off from the vaginal cavity and causes inconsistent results
Solution Approach 1:
The device employs an inflatable structure that can dynamically adjust its volume and shape. The cylindrical body includes inflatable tubular ribs and annular spaces that can be filled with fluid or gas to adapt to the patient's anatomy, providing customized retention force without excessive pressure, thereby preventing slippage while maintaining comfort.
Solution Approach 2:
The device allows adjustment of physical parameters such as volume, pressure, and shape through inflation/deflation mechanisms. The inflatable tubular ribs and annular spaces can be adjusted to change the device's firmness and contour, enabling it to maintain optimal retention while adapting to patient comfort requirements.
2Reliability
If manual pressure is applied using cotton gauze or plastic vaginal tubes during surgeries, then gas leakage is prevented, but the procedure becomes complex and requires additional manual intervention
Solution Approach 1:
The device provides self-retaining occlusion through its inflatable structure that automatically maintains pressure and seal against the vaginal walls once positioned. The distension control mechanism allows the device to self-adjust and maintain gas tight seal without requiring continuous manual pressure application, reducing procedural complexity.
Solution Approach 2:
The device uses pneumatic or hydraulic inflation of its cylindrical body, tubular ribs, and annular spaces to create and maintain the occlusion seal. This eliminates the need for manual pressure application and provides consistent, reliable gas sealing throughout the surgical procedure.
3Manufacturing precision
If the device is made inflatable with distension control mechanism, then uniform distension and adjustable fitment are achieved, but the device structure becomes more complex
Solution Approach 1:
The device is segmented into multiple inflatable components including the cylindrical body, tubular ribs, and annular spaces. Each segment can be independently inflated or deflated through separate channels, allowing precise control over the distribution and uniformity of distension forces applied to the vaginal walls.
Solution Approach 2:
The device utilizes flexible polymeric membranes and inflatable chambers that naturally distribute pressure uniformly when inflated. The flexible nature of these components allows them to conform to the vaginal anatomy while maintaining consistent distension, achieving manufacturing precision through material properties rather than complex mechanical mechanisms.
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 device effectively controls urinary incontinence, securely collects menstrual blood, and prevents gas leakage during surgeries by providing a snug, adjustable fit and controlled distension, enhancing user comfort and surgical outcomes without manual pressure.
Implementation Method 1
The device comprising of a squeezable and inflatable cylindrical body made of single or two layered flexible polymeric membrane
Implementation Method 2
The posterior end is provided with a tubular opening having gas flow pipe which is connected to the distension control and release mechanism

AI summary
The invention relates to a Multipurpose Vaginal Occlusion and Distension Device with Distension Controller, which helps patients with Female Stress Urinary Incontinence and for Fecal Incontinence. It comprises of double layered cylindrical body (101) making inflatable annular space and with closed anterior (103) and posterior (104) wall provided with inflatable tubular silicon ribs (103a, 104a), but the posterior end is provided with gas flow tube (106) connectable to the “Distension control and release mechanism” by which the cylindrical cavity (107), annular space, tubular ribs at both the end can be inflated. But the same device can be used, if the anterior end (301) is opened for collecting menstrual blood during Menstrual Cycle as an alternative to menstrual cups and pads. The same can be used preferably with partly opened mouth (403) by Doctors during Laparoscopic Surgeries as a pneumoseal and as a vaginal blocker to prevent the gas leakage through the vaginal canal while performing the colpotomy and thereafter during vaginal vault suturing.
