Surgical Drain Anchoring Pad with Adhesive Recess and Ridge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Surgical drains often lead to issues such as kinking, incorrect positioning, or dislodging, which can increase the risk of infection and hinder the healing process by preventing proper fluid drainage from body cavities.
Innovation Solution
A surgical drain anchoring device with a resilient, flexible pad, a central aperture, and a slit that secures the drain with a neck member and tie, along with an outer ridge for attaching a drainage bag, ensuring stable attachment to the skin using adhesive or sutures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a surgical drain is used to drain fluid from body cavities, then fluid drainage function is improved, but the risk of kinking, dislodging, or incorrect positioning increases
Solution Approach 1:
The patent introduces a pad as an intermediary component between the surgical drain and the patient's body. The pad includes a recess that receives the surgical drain, positioning it in a fixed orientation, and an adhesive layer that secures the entire assembly to the patient's body. This intermediary structure prevents kinking, dislodging, and incorrect positioning while maintaining the drainage function.
2Reliability
If the surgical drain is secured firmly to prevent dislodging, then positioning stability is improved, but the complexity of the device increases
Solution Approach 1:
The patent combines multiple functions into a single integrated pad structure. The pad integrates the positioning recess, the adhesive layer for securing to the body, and the protective cover elements into one component. This merging approach provides stable drain positioning without requiring multiple separate devices or complex assembly procedures.
3Reliability
If a protective cover is added to prevent kinking, then the reliability of drainage is improved, but the ease of operation decreases
Solution Approach 1:
The patent employs a dynamic cover system that can be opened and closed. The cover includes a flap or removable portion that allows access to the surgical drain when needed for manipulation or inspection, while automatically or manually closing to protect against kinking and contamination when not in use. This dynamic design maintains drainage reliability while preserving ease of operation.
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 securely anchors the surgical drain, reducing the risk of infection and fluid accumulation by maintaining proper drainage, facilitating the healing process and preventing organ impairment.
Implementation Method 1
The lower surface of the pad is configured for attaching onto the skin of the patient using an adhesive layer

AI summary
The surgical drain anchoring device includes a resilient, flexible pad having an upper surface, an opposing lower surface, a centrally positioned aperture, and a slit extending radially outward from the aperture to the perimeter of the device. A neck member positioned on the upper surface defines a central channel aligned with the aperture, and a tapered member aligned with the aperture extends from the lower surface so that a surgical drain can pass through the neck, the aperture, and the tapered member. An outer ridge member adapted for attachment of an external drainage bag thereto also extends from the upper surface. The external drainage bag includes a primary opening configured to attach onto the outer ridge member and a secondary opening configured to drain fluid from the drainage bag. The device can also include a strap, tie, or clip configured for securing the neck around the surgical drain.
