Abscess Irrigation Nozzle With Segmented Outlet Ports
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current irrigation devices are ineffective for deep tissue wounds and abscesses, as they lack sufficient pressure and fluid dispersion to thoroughly cleanse and debride tissues, often leading to incomplete drainage and recurrence of infections.
Innovation Solution
A novel irrigation device with a slender, elongated nozzle and multiple outlet ports designed to maintain pressure and deliver a dispersed stream of irrigation solution, accompanied by a compressible reservoir housing for manual pressure application, allowing for effective penetration and cleansing of deep tissue wounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If standard irrigation devices are used on deep tissue wounds, then the wound can be accessed, but insufficient pressure and fluid dispersion prevent effective cleansing and debridement
Solution Approach 1:
The irrigation device divides the fluid delivery system into multiple outlet ports (at least two) arranged to provide both central and peripheral flow paths. This segmentation allows simultaneous delivery of irrigation fluid to different depths and zones of the wound, achieving effective debridement without requiring complex pressurization systems.
Solution Approach 2:
Different outlet ports are positioned at different locations and orientations to deliver irrigation fluid to specific zones of the wound. The central outlet provides deep penetration while peripheral outlets provide broader surface coverage, creating localized quality variations in fluid delivery that match the wound's anatomical needs.
2Reliability
If a single large outlet port is used, then simple device structure is maintained, but inadequate fluid dispersion prevents thorough cleansing of deep tissue
Solution Approach 1:
The single large outlet is divided into multiple smaller outlet ports (at least two) with different orientations. This segmentation provides superior fluid dispersion and coverage of deep tissue surfaces compared to a single large port, while maintaining relatively simple nozzle structure that can be manufactured as an integrated component.
Solution Approach 2:
The outlet ports are oriented in different directions (e.g., one port oriented longitudinally, another transversely) to deliver fluid along different spatial dimensions. This multi-dimensional fluid delivery approach achieves thorough dispersion throughout the three-dimensional wound cavity without requiring complex mechanical mechanisms.
3Reliability
If high pressure irrigation is applied, then contaminants are effectively removed, but risk of driving bacteria deeper into tissue increases
Solution Approach 1:
By dividing the irrigation flow into multiple outlet ports, the pressure is distributed across multiple streams rather than concentrated in a single high-pressure jet. This segmentation reduces the risk of driving bacteria deeper into tissue while maintaining effective contaminant removal through combined fluid action from multiple directions.
Solution Approach 2:
The device uses multiple outlet ports to deliver irrigation fluid in a dispersed manner, applying partial pressure through each port rather than excessive pressure through a single port. This approach achieves adequate contaminant removal while minimizing tissue damage risk.
4Reliability
If the incision is made as small as necessary to minimize scarring, then cosmetic outcome is improved, but drainage and irrigation effectiveness is reduced
Solution Approach 1:
The multi-outlet nozzle delivers irrigation fluid through multiple small openings that can access deep tissue through a small incision. The segmented fluid delivery compensates for the limited access provided by a small incision, maintaining effective drainage and irrigation while minimizing scarring.
Solution Approach 2:
The outlet ports are oriented in different directions to deliver fluid along multiple spatial paths through the small incision. This multi-dimensional approach allows effective irrigation of deep tissue cavities despite the limited size of the access opening.
