Ostomy Accessory With Wireless Closure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ostomy pouching systems cause discomfort to patients post-surgery, as they require external attachment and may not be suitable for novel ostomy procedures that involve internal reservoirs and constriction devices for managing intestinal stomas.
Innovation Solution
An ostomy accessory with a tube-like insertion portion and a collapsible or pump-based evacuation portion that allows for the evacuation of faecal matter from an internal reservoir, either surgically created or artificial, using a constriction device that can be controlled remotely to open and close access between the intestine and stoma.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pouching systems are used to collect and contain ostomy output, then the stoma is effectively covered and contained, but the patient experiences discomfort and limited ability to resume normal activities
Solution Approach 1:
The invention extracts the collection function from the traditional external pouch and relocates it to an internal reservoir formed by the intestine itself through surgical closure. The accessory device inserts through the stoma to access and evacuate this internal reservoir, separating the containment function (performed by the closed intestine) from the evacuation function (performed by the accessory device), thereby eliminating the need for uncomfortable external pouches while maintaining effective stoma management
Solution Approach 2:
The accessory device acts as an intermediary between the internal ostomy reservoir and the external environment. It provides a controlled interface for evacuating contents from the internal reservoir through the stoma without requiring external pouches, thereby mediating between the need for internal containment and external disposal while improving patient comfort and mobility
2Quantity of substance
If a removable pouching system is attached to the stoma, then the stoma output is collected and contained, but the patient suffers from the burden of external pouches
Solution Approach 1:
The invention implements a nested structure where the evacuation accessory is inserted through the stoma and accesses the internal reservoir that is nested within the patient's abdomen. The collapsible collection element within the accessory can expand to contain output and then collapse for evacuation, creating a nested arrangement of containment structures that eliminates external pouches while maintaining collection functionality
Solution Approach 2:
The invention employs dynamic, collapsible collection elements within the accessory device that can expand to contain output and collapse for evacuation. This dynamic behavior allows the same structure to serve multiple functions (collection and evacuation) without requiring permanent external pouches, reducing device complexity and patient burden while maintaining effective output management
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 accessory reduces discomfort by enabling the evacuation of faecal matter without the need for external pouches, allowing patients to manage their intestinal output more comfortably and conveniently, particularly suitable for both traditional and novel ostomy procedures.
Implementation Method 1
the evacuation portion comprises a substantially collapsible expandable reservoir, such as an expandable bag or a pouch, which in one embodiment is self expandable

AI summary
An ostomy accessory for an intestinal stoma of a mammal patient. The accessory comprises an insertion portion adapted to be inserted into an natural intestinal stoma of an ostomy and an evacuation portion adapted to evacuate fecal matter from said insertion portion and from an intestine connected to the intestinal stoma of the patient. The intestine is formed to an ostomy reservoir, and the insertion portion is adapted to be inserted into the ostomy reservoir created by the intestine. The insertion portion is further adapted to cause the intestine to open for flow of the fecal matter out of the intestinal stoma when the insertion portion is positioned into the stoma. The accessory further comprises a wireless transmitter adapted to communicate with a wireless receiver. The wireless transmitter is adapted to co-operate with and open an artificial closure acting on the outside of the intestine, when the insertion portion is positioned adjacent to or in indirect contact therewith, to allow the fecal matter to be evacuated through the intestine and stoma using the ostomy accessory, upon a wireless signal sent from the wireless transmitter.
