Solution Overview
Problem
Current ostomy bag systems face challenges in effectively managing wound sites, including infection, pain, and complications, while also struggling to enhance coupling of medical devices to patients and facilitate healing.
Innovation Solution
A medical device system comprising a bag, a pad, and tubes configured to provide negative pressure therapy, which includes a pump assembly to apply negative pressure, a filter assembly to manage material from the wound site, and a pad with a central lumen and adhesive for secure coupling to the patient.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a traditional ostomy bag system is used to collect visceral contents, then the bag can effectively collect and store intestinal discharge, but the wound site becomes susceptible to infection, skin irritation, and other complications
Solution Approach 1:
The system divides the collection device into separate functional components: a pad with adhesive for secure coupling to the skin, a bag for collecting visceral contents, and a tube for negative pressure therapy. This segmentation allows the pad to protect the wound site while the bag collects discharge, resolving the contradiction between effective collection and wound protection
Solution Approach 2:
The tube acts as an intermediary component that delivers negative pressure therapy to the wound site through the pad. This intermediary mechanism actively protects the wound site from infection and irritation while the bag continues to collect visceral contents, thus resolving the harmful effects without compromising collection effectiveness
2Reliability
If negative pressure therapy is applied to the wound site, then wound healing is enhanced and infection risk is reduced, but the device complexity increases with additional components like pump assembly and filter assembly
Solution Approach 1:
The system merges multiple functions into an integrated device: the pad combines adhesive coupling with negative pressure delivery, the tube provides both fluid pathway and therapy delivery, and the bag serves as both collection container and structural support. This merging reduces device complexity while maintaining wound healing benefits
Solution Approach 2:
The pad serves multiple functions simultaneously: it adheres to the skin for secure coupling, delivers negative pressure therapy to the wound site, and collects fluid discharge. The tube also serves dual purposes as both a structural support and a therapy delivery mechanism. This multi-functionality reduces the need for separate components, thereby reducing device complexity while maintaining therapeutic effectiveness
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

Implementation Method 1
the pump assembly may apply negative pressure to the tube
Implementation Method 2
a filter assembly may be coupled to the tube and configured to filter material received from the wound site
Implementation Method 3
The pad may include an adhesive on a first side of the pad

AI summary
According to one aspect, a medical device system may comprise a bag including a first opening; a pad coupled to the bag proximate to the first opening; and a tube including a distal portion. The distal portion may be coupled to the pad and includes at least one opening; and the tube may be configured to provide negative pressure therapy to a wound site.
