Suction-Based Medical Dressing for Dermal Irrigation Fluid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During dermal medical irrigations, controlling fluid overflow and focusing on the surgical procedure while ensuring fresh fluid delivery is challenging due to manual pressure application and the need to hold absorbent pads away from the target area.
Innovation Solution
A suction-based medical dressing with a vacuum-inducing source and absorbent gauze-covered bifurcated tubes, surrounded by an occlusive sheet with an adhesive strip, which creates negative pressure to draw and contain ambient fluid for efficient removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pressure application is used for dermal irrigation, then the surgical procedure can be performed, but fluid overflow and spillage occur
Solution Approach 1:
The patent introduces an intermediary suction system with a tube and vacuum source that acts as a mediator between the irrigation fluid and the patient. This intermediary system actively manages fluid removal, preventing overflow and spillage while allowing the surgical procedure to proceed uninterrupted.
Solution Approach 2:
The patent replaces the manual mechanical pressure application system with an automated suction-based system. The vacuum source automatically controls fluid removal, eliminating the need for manual pressure control and absorbent pad management, thereby preventing fluid spillage.
2Productivity
If absorbent pads are held away from the target area, then fresh fluid delivery is maintained, but fluid overflow cannot be controlled
Solution Approach 1:
The suction tube acts as an intermediary device that simultaneously enables fresh fluid delivery and controls overflow. By positioning the tube at the target area, it allows continuous irrigation while actively removing excess fluid, eliminating the need to hold pads away from the surgical site.
Solution Approach 2:
The patent implements continuous useful action by maintaining constant suction throughout the irrigation process. This continuous fluid removal ensures that fresh fluid can be delivered without interruption while overflow is continuously controlled, improving productivity without compromising safety.
3Adaptability or versatility
If different volumes and pressures of fluid are delivered, then irrigation effectiveness is improved, but controlling fluid overflow becomes more difficult
Solution Approach 1:
The suction system provides continuous feedback on fluid accumulation at the surgical site. By monitoring the suction flow and adjusting vacuum pressure accordingly, the system adapts to different irrigation requirements while automatically controlling overflow, reducing the complexity of manual fluid management.
Solution Approach 2:
The patent utilizes parameter changes by adjusting vacuum pressure levels to match different irrigation requirements. The suction system can operate at varying pressure levels to handle different fluid volumes and viscosities, maintaining irrigation effectiveness while simplifying overflow control through automated parameter adjustment.
4Reliability
If medical professionals focus on the surgical procedure, then surgical quality is maintained, but fluid management becomes problematic
Solution Approach 1:
The suction system performs self-service by automatically managing fluid removal without requiring constant medical professional intervention. The system autonomously controls fluid overflow while maintaining appropriate suction levels, allowing surgeons to focus on the procedure while fluid management handles itself.
Solution Approach 2:
The suction tube serves as an intermediary that separates surgical tasks from fluid management tasks. This intermediary device handles the complex fluid management functions automatically, enabling medical professionals to maintain surgical quality without being burdened by fluid control difficulties.
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 solution effectively minimizes fluid spillage and overflow, maintaining a controlled environment for dermal irrigation by actively drawing and containing the fluid, reducing the burden on medical professionals and preventing bio-hazardous fluid from spilling onto patients or the floor.
Implementation Method 1
The vacuum assembly is operably configured to induce negative pressure within the tube channel and the bifurcated tube channel. The negative pressure in the tube channel causes ambient fluid absorption through a plurality of apertures that form in the tube.
Implementation Method 2
The absorbent gauze material covers a sufficient area of the bifurcated tube portions, so as to draw the ambient fluid from the patient's skin towards the apertures in the bifurcated tube portions.
Data Source
AI summary
A suction-based medical dressing assembly and method of dermal irrigation provides a flexible tube that is fluidly coupled to at least two bifurcated tube portions defined by a plurality of apertures. The tube has a proximal end opening for discharging ambient fluid. The length of the bifurcated tube portions is surrounded by an absorbent gauze material covered substantially with an occlusive sheet material, and having an adhesive strip thereon. A vacuum assembly creates a negative pressure in the tubes. The ambient fluid is absorbed by the absorbent material, and the negative pressure sucks the fluid through the apertures in the bifurcated tube portions for discharge through the opening in the tube. In operation, a patient applies the adhesive side of the occlusive device to the skin where liquid removal is desired and activates the vacuum-inducing source, thereby causing fluid runoff from the patient to be effectively removed for disposal.
