Adhesive Skin Prep Exposing Pore Bacteria for Antibacterial Penetration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for preparing skin before surgery do not effectively penetrate the dermal layer to reduce Cutibacterium acnes bacteria, leading to potential infections during shoulder arthroplasty procedures, as they fail to fully expose bacteria in skin pores, limiting the effectiveness of antibacterial agents.
Innovation Solution
A method involving the application and removal of a first adhesive member to expose bacteria in skin pores, followed by the application of an antibacterial agent, utilizing a roller with a cylindrical adhesive member and an absorbent material to ensure the agent reaches and kills bacteria within the pores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an antibacterial agent is applied directly to the skin surface, then the application process is simple, but the agent cannot effectively reach bacteria deep in skin pores due to blocking material
Solution Approach 1:
The patent applies preliminary action by first removing surface material (sebum, dead skin cells) before applying the antibacterial agent. This preparatory step exposes the bacteria in the pores, allowing the subsequent antibacterial application to be effective. The two-step process (material removal then agent application) ensures the antibacterial agent can reach its target without being blocked by surface debris.
Solution Approach 2:
The patent uses an intermediary substance or mechanism to facilitate the delivery of the antibacterial agent. The removal of surface material acts as an intermediary step that creates a pathway for the agent to reach deep into the pores. This intermediary action bridges the gap between the surface application and the deep pore target, solving the penetration problem.
2Reliability
If skin preparation focuses only on surface cleaning, then the process is quick and simple, but bacteria in the dermal layer remain untreated
Solution Approach 1:
The patent performs preliminary removal of surface material (sebum, dead skin cells) to expose the underlying bacteria in the pores. This preparatory action enables subsequent antibacterial treatment to penetrate effectively to the dermal layer where C. acnes bacteria reside, ensuring thorough disinfection without requiring excessive time.
Solution Approach 2:
The patent changes the physical or chemical parameters of the skin surface by removing the blocking material layer. This parameter change (removal of surface debris) transforms the skin surface from a blocked state to an exposed state, allowing antibacterial agents to penetrate to the required depth efficiently, thus achieving deep cleaning without proportionally increasing time.
3Reliability
If deep penetration of antibacterial agents is achieved through extended contact time, then bacteria in pores are effectively killed, but the surgical procedure is delayed
Solution Approach 1:
The patent performs the material removal step beforehand, which exposes the pores and enables rapid penetration of the antibacterial agent. This preliminary exposure action eliminates the need for extended contact time, allowing the surgical procedure to proceed efficiently without sacrificing bacterial elimination effectiveness.
Solution Approach 2:
The patent changes the surface condition parameter by removing blocking material, which dramatically improves the penetration rate of the antibacterial agent. This parameter change allows the agent to reach deep pore bacteria quickly, maintaining high elimination effectiveness while minimizing the time required, thus preserving surgical productivity.
